The contours of the collective action necessary to limit climate change remain difficult to discern. In this context, societal corporatist political processes, fueled by crisis narratives, have shown some promise as political devices for mobilizing people. Corporatist processes have, historically, brought political competitors like employers and labor unions together to negotiate compacts that have advanced collective goods during times of crisis. In response to the climate crisis in the Global South, affluent donor groups, state officials, some farmers, and indigenous peoples have begun to assemble corporatist-like coalitions to pursue climate stabilization. A comparative case study of efforts to promote sustainable cattle ranching through the spread of silvopastoral landscapes in Colombia and Ecuador illustrates this political dynamic, its shortcomings, and its accomplishments.

An estimated 7.7 million Venezuelans have fled a severe humanitarian crisis in their country, most (70%) to other middle-income host countries in the same Andean region. Migration-related exposures during periconception and other critical gestational periods can adversely impact maternal-perinatal outcomes. Emerging evidence suggests that Venezuelan refugee and migrant women (VRMW) who migrate to Andean host countries are at-risk for delivering preterm and low birthweight infants and for Cesarean-sections. However, relatively few studies have examined obstetrical complications that could contribute to these or other short- and longer-term health outcomes of VRMW and/or their offspring. Our exploratory study analyzed four recent years of national hospital discharge data (2018–2021) from Ecuador to compare the primary discharge diagnoses of VRMW (n = 29,005) and Ecuadorian nationals (n = 1,136,796) for ICD-10 O code obstetrical complications related to or aggravated by pregnancy, childbirth, or the puerperium. Our findings indicated that VRMW were hospitalized for 0.5 days longer than Ecuadorian reference group women and they had higher adjusted odds (aOR) for a primary discharge diagnosis for obstetrical complications including preeclampsia (aOR:1.62, 95% CI:1.55,1.69), preterm labor (aOR:1.20, 95% CI:1.11,1.31), premature rupture of membranes (aOR: 1.72, 95% CI:1.63,1.83), oligohydraminos (aOR:1.24, 95% CI:1.12,1.36), obstructed labor (aOR: 1.39, 95% CI:1.31,1.47), perineal lacerations/other obstetric trauma (aOR:1.76, 95% CI:1.63, 1.91), STIs (aOR:2.59, 95% CI:1.29,2.92), anemia (aOR:1.33, 95% CI:1.24,1.42), and ectopic pregnancy (aOR:1.16 95% CI:1.04,1.28). They had similar aOR for diagnosed gestational diabetes and spontaneous abortion (SAB) compared to the reference group but a reduced aOR for genitourinary infections (aOR:0.79, 95% CI:0.74,0.84) and early pregnancy hemorrhage not ending in SAB (aOR:0.43, 95% CI:0.36,0.51). Our findings underscore the vulnerability of VRMW for a number of potentially serious obstetrical complications with the potential to adversely impact the short- and longer-term health of mothers and their offspring. Future studies should collect more detailed information on the migration status, experiences, and exposures of MRMW that influence their risk for obstetrical complications. These are needed to expand our findings to better understand why they have excess risk for these and to inform social and public health policies, programs and targeted interventions aimed at reducing the risk of this vulnerable refugee and migrant group.

Recent field expeditions to the Andes and herbarium research resulted in the discovery of a new species of Drymonia (Gesneriaceae). Drymonia tomentosa J.L.Clark & Clavijo is described from the western Andean slopes of northern Ecuador and southern Colombia. The new species is differentiated from other congeners by the presence of a tomentose indumentum on the stems, stout shoots, broadly oblong leaves, and calyx lobes with broadly rounded apices. Based on IUCN guidelines, a preliminary conservation status is assigned as Least Concern (LC). [ABSTRACT FROM AUTHOR]

The Ecuadorian arc is composed of an unusually high number of volcanoes, organized as along-arc alignments and across-arc clusters, in a relatively small area. Although several geochronological studies have been carried out in the last three decades, the eruptive history of the central zone of the arc remains poorly documented, preventing analysis of the initiation of volcanism of the whole arc. In this study, we present new K–Ar ages obtained from this central area, referred to as the Quito segment. These results were then incorporated into an updated comprehensive geochronological database of about 250 ages, allowing us to describe, at the arc scale, the spatial and temporal evolution of Quaternary volcanism in Ecuador. About eighty Quaternary volcanoes have been identified in the Ecuadorian Andes, 45 of which have been radioisotopically dated and/or identified as active or potentially active. The volcanic arc developed in three stages, characterized by an increase in the total number of active volcanoes. During the oldest Plio-Early Pleistocene stage, documented volcanic activity was mostly concentrated in the Eastern Cordillera of the Quito segment, with minor effusive eruptions in the southern Back-Arc. Since ~ 1.4 Ma, activity has spread to the surroundings of the Quito segment, and new edifices also appeared in the Western Cordillera and the Inter-Andean Valley. Towards the end of this intermediate stage (i.e., ~ 800 ka), volcanism occurred in isolated areas north and south of the Inter-Andean Valley. Finally, the late and current has been characterized by a remarkable increase in volcanic activity since ~ 600 ka. About 50 volcanoes were active during this stage. The spatial distribution of the Ecuadorian arc volcanism seems to be guided by deep mechanisms (i.e., slab geometry and age, amount and composition (fluids and melts) of slab input, mantle heterogeneities) and old crustal tectonic structures of the Western Cordillera, while neotectonics seems to influence the development of stratovolcanoes. In addition, we note that the spatial and temporal evolution of volcanism highlights the influence of the Carnegie Ridge and the young Nazca crust on the thermal regime of the subduction system, which in turn increases of volcanic activity in Ecuador.

Invalid votes are pervasive in many democracies and can threaten the legitimacy of elections. While often associated with factors such as choice complexity and disengagement, especially under compulsory voting rules, intentional ballot spoiling can also signal a political protest. We examine the argument that spoiling ballots as protest should occur under compulsory voting where voters perceive limited legitimacy to the electoral process and a lack of viable options. Using municipal elections in Ecuador, a context featuring both compulsory voting and a period of democratic erosion, we examine subnational variation in both spoiled and blank ballots. While factors related to sophistication and choice complexity explain variation in both forms of invalid voting, our results also reveal patterns consistent with the expectation that spoiled ballots reflect a protest of a lack of competition in the political system. Specifically, we find that areas opposed to Rafael Correa's dominant party had a higher rate of spoiled ballots in the 2014 mayoral elections, a period when party dominance was consolidated and competition weak. This pattern declined in 2019 when the system's competitiveness increased. A separate analysis of the 2019 elections for the Correa-era participatory governance body suggests continued use of spoiled ballots as protest by opposition voters, but primarily in higher connectivity areas where the online coordination on use of this tactic may have had greater influence. Overall, our study sheds light on factors shaping invalid vote patterns in compulsory systems and highlights spoiled ballots' potential as a means to signal protest under conditions where some voters would perceive a decline in the legitimacy of democratic institutions.

Purpose of Review: Highly pathogenic avian flu viruses (HPAIVs) are considered one of the main candidates for the next pandemic due to its current trend to improve infectivity towards mammal species. The ongoing influenza A H5N1 clade 2.3.4.4b outbreak affecting the Americas has spread from North America to South America since 2022 and have recently reached Antarctica. Besides an unprecedented impact in poultry industry, it has also spread through migratory bird to aquatic mammals causing massive death events in South America rising concern about a potential mammal-to-mammal transmission. Moreover, H5N1 human cases in Ecuador and Chile, and outbreaks in dairy cattle in the USA with cattle-to-human transmission cases made the Pan America Health Organization to declare an epidemiological alert for H5N1 in the Americas in June 2024. Recent Findings: We reviewed the current situation of H5N1 epidemic in Ecuador where farm and backyard poultry outbreaks, a human case and several events of infection in wild bird species have been notified to the World Health Organization and the World Organization for Animal Health from 2022 to 2024. A detailed description of the H5N1 epidemiological scenario is provided and a phylogenetic analysis for the eight H5N1 sequences available for Ecuador is done where multiple entries of H5N1 strains are described. Summary: HPAIVs sentinel surveillance assisted by genome surveillance is fundamental for a successful avian flu control and prevention program. We found some potential gaps in H5N1 surveillance in Ecuador considering that poultry outbreaks are geographically segregated from wild bird outbreaks; this fact points out the need of a more intense sentinel surveillance including poultry, wildlife and humans under a One Health approach. Moreover, H5N1 genomic surveillance must be improved as only 8 genome sequences have been uploaded to public repositories in almost two years of avian flu epidemic. HPAIVs genomic surveillance is crucial to follow up the dynamics and evolution of those viruses to assist an effective avian flu control and prevention program in Ecuador. [ABSTRACT FROM AUTHOR]

Purpose: Accurate height and weight measurement can be challenging in older adults and complicates nutritional status assessment. Other parameters like the neutrophil-to-lymphocyte ratio (NLR) and the lymphocyte count (LC) could be an option to these measurements. We aimed to test these variables as subrogates of body mass index (BMI) or calf-circumference (CC) for malnutrition screening in community-dwelling older adults. Methods: This is a secondary analysis from the Salud, Bienestar y Envejecimiento (SABE) survey from Ecuador (2009). Includes data on demographics, health-related factors, physical assessments, and complete blood count, allowing to calculate NLR and LC to be used as part of the Mini Nutritional Assessment (MNA), instead of the BMI. Consequently, 4 models were included: standard MNA, MNA-CC, MNA-NLR and MNA-LC. Finally, age, sex, and comorbidities were considered as confounding variables. Results: In our analysis of 1,663 subjects, 50.81% were women. Positive correlations with standard MNA were found for MNA-NLR (Estimate = 0.654, p < 0.001) MNA-CC (Estimate = 0.875, p value < 0.001) and MNA-LC (Estimate = 0.679, p < 0.001). Bland-Altman plots showed the smallest bias in MNA-CC. Linear association models revealed varying associations between MNA variants and different parameters, being MNA-NLR strongly associated with all of them (e.g. Estimate = 0.014, p = 0.001 for albumin), except BMI. Conclusion: The newly proposed model classified a greater number of subjects at risk of malnutrition and fewer with normal nutrition compared to the standard MNA. Additionally, it demonstrated a strong correlation and concordance with the standard MNA. This suggests that hematological parameters may offer an accurate alternative and important insights into malnutrition. [ABSTRACT FROM AUTHOR]

Areas identified as escape zones for Pseudocercospora ulei, the causal agent of South American Leaf Blight (SALB), are being sought for the development of profitable rubber growing, as high-yielding Asian clones can be grown there without suffering repeated defoliation caused by epidemics of the disease. A performance trial with 10 clones was set up in 2006 in such an escape zone in Ecuador with non-American clones whose high production potential is acknowledged elsewhere in the world, some of which are recommended on a commercial scale. Production results over seven years, between 2013 and 2019, indicated a very high potential for this material in this new region, reaching average yields of 2.5 t/ha/year for clones PB 280, PB 312 and PB 314, and 1.85 t/ha/year for the control clone RRIM 600, despite a very pronounced 5-month dry season. However, the risks of wind damage and tapping panel dryness were found to be very high for PB 312 and PB 314. Clone PB 280 proved to perform best overall, with 93% of trees in production and one of the lowest Tapping Panel Dryness (TPD) rates. This clone, distinguished by its medium high latex metabolism and a high sucrose reserve, presents a highly promising alternative for the cultivation of rubber trees in escape zones. This is particularly relevant in situations where the phytosanitary risk associated with P. ulei is constrained. [ABSTRACT FROM AUTHOR]

The mortiño (Vaccinium floribundum Kunth), belonging to the Ericaceae family, is a native species of the Ecuadorian paramos. It has a shrub-like habit and produces edible fruits. In the Neotropics, it is primarily found in the Andes of Colombia and Ecuador, thriving in humid environments up to an elevation of 3700 m above sea level. In this review, a selection of studies was carried out that evaluated the taxonomy, reproduction biology, and nutraceutical, environmental properties, and industrial use of the mortiño (V. floribundum). The data gathered from various bioassays were essential in determining the appropriate techniques for tissue differentiation and assessing the quality of resulting plants. This work aims to generate a deep knowledge of the cultivation of mortiño, as well as the properties of its fruits and the benefits they provide for health. These are rich in compounds with antioxidant activity, so the consumption of V. floribundum fruits is related to health benefits. Besides, the environmental role of V. floribundum and its applications in various industries, especially in the development of nanoparticles contributes to the valorization of this plant. Overall, this research contributes to establishing sustainable methods for the propagation of Vaccinium floribundum, ensuring its successful cultivation and utilization for both commercial purposes and ecological preservation.

The essential oil obtained from the dry leaves of Gynoxys szyszylowiczii Hieron. was described in this study for the first time. The chemical analysis, conducted on two stationary phases of different polarity, permitted to identify sixty-four compounds, that were quantified with at least one column. The main components, on a non-polar and polar stationary phase respectively, were germacrene D (21.6–19.2%), α-pinene (4.4–4.9%), n-tricosane (4.3% on both columns), (E)-β-caryophyllene (3.3–4.3%), 1-docosene (3.2–2.8%), α-cadinol (2.8–3.1%), and cis-β-guaiene (2.6–3.0%). This investigation was complemented by the enantioselective analysis of some major chiral compounds, carried out on two chiral selectors based on β-cyclodextrines. As a result, (S)-(+)-α-phellandrene, (S)-(+)-β-phellandrene, and (1S,2R,6R,7R,8R)-(+)-α-copaene appeared enantiomerically pure, whereas α-pinene, β-pinene, terpinen-4-ol, and germacrene D were detected as scalemic mixtures. Finally, linalool was practically racemic. The distillation yield, analytically calculated by weight of dry plant material, was 0.03%. [ABSTRACT FROM AUTHOR]

We present a flora and fauna dataset for the Mira-Mataje binational basins. This is an area shared between southwestern Colombia and northwestern Ecuador, where both the Chocó and Tropical Andes biodiversity hotspots converge. We systematized data from 120 sources in the Darwin Core Archive (DwC-A) standard and geospatial vector data format for geographic information systems (GIS) (shapefiles). Sources included natural history museums, published literature, and citizen science repositories across 13 countries. The resulting database has 33,460 records from 6,821 species, of which 540 have been recorded as endemic, and 612 as threatened. The diversity represented in the dataset is equivalent to 10% of the total plant species and 26% of the total terrestrial vertebrate species in both hotspots. The dataset can be used to estimate and compare biodiversity patterns with environmental parameters and provide value to ecosystems, ecoregions, and protected areas. The dataset is a baseline for future assessments of biodiversity in the face of environmental degradation, climate change, and accelerated extinction processes. [ABSTRACT FROM AUTHOR]

In the traditional fishing sector of Ecuador, integrating a gender perspective enhances sustainability and addresses climate change by recognizing the vital roles and knowledge of women in fisheries management. The objective of this study was to validate the content, comprehension, and construction of the designed questionnaire. Additionally, it is intended to identify perceptions of sustainability and climate change amongst women and men in fisheries, and compare their views on the dimensions of sustainability and climate change. The research implemented a questionnaire with a metrically satisfactory scale, providing information on how men and women perceive sustainability and climate change in the artisanal fishing sector. The data were collected by designing an ad hoc questionnaire denominated "Gender perception as regards sustainability and climate change" following a process in which the validity of the content (experts > 0.5823; Content Validity Ratio (CVR) > 6.1; Content Validity Index (CVI) > 0.852), decompression (pilot study, N = 30) and construct (KMO = 0.71) were analyzed. The results of the internal consistency reliability analysis indicated that the Likert scale had a high index of reliability, as evidenced by Cronbach's Alpha coefficient of 0.70. This analysis provided evidence of the structure and validity of the scale, resulting in a reliable, integral, and short tool with which to measure perceptions of sustainability and climate change. The questionnaire was administered to 1464 people employed in the traditional fishing industry (17.14% women) in 40 fishing community ports near the coastal profile of Ecuador (Esmeraldas and Manabí). Most of those surveyed stated that the current traditional fishing quotas are not very sustainable in the long term (47.10%, n = 690) and that climate change may significantly negatively impact catch rates (50.30%, n = 736). Finally, the Wilcoxon test of tests confirmed that women had significantly more positive attitudes than men towards sustainability (3.03 ± 0.69) and climate change (3.35 ± 0.64).

Coastal El Niño events—marine heatwaves instances in the far eastern Tropical Pacific during otherwise basin-scale neutral or cold conditions—can have severe societal impacts for countries along the west coast of South America, as exemplified by the 2017 and 2023 Peru-Ecuador floods. Due to the brevity of the observational record, it is not well understood whether these events are driven by local or large-scale processes. Here, to overcome this limitation we use a data-driven modeling approach to address their return period and forcing mechanisms. It is shown that extreme coastal El Niño events are a local manifestation in the eastern tropical Pacific of the constructive interactions of the Pacific Meridional Modes (PMM). Specifically, the North PMM yields a dipole-like anomaly SST pattern along the equator that favors its development, while the positive phase of the South PMM reinforces it. A smaller group of more moderate coastal events are remotely driven by zonal wind anomalies in the western tropical Pacific without the PMMs' influence. The role of PMMs in the development of extreme coastal El Niño suggests that they may be more predictable than previously thought. [ABSTRACT FROM AUTHOR]

This study examines the complex relationships between Psychological Capital, family business, ownership, gender, and firm performance during the COVID-19 pandemic. The study examines the effects of these variables on firm performance and explores the empirical interaction effects. The findings reveal that Psychological Capital positively influences firm performance, supporting the hypothesis that owners with higher Psychological Capital contribute to better business outcomes. Additionally, family business and ownership significantly impact firm performance, indicating that family involvement and concentrated ownership drive organizational success. Surprisingly, the results indicate a negative impact of gender on firm performance, suggesting that firms managed by women are perceived as less successful. The study also explores the interaction effects and finds that the positive relationship between Psychological Capital and firm performance is amplified in family businesses. However, gender does not moderate this relationship, indicating that women Owners face challenges in translating their Psychological Capital into firm performance in the emerging economy of Ecuador. The results provide insights into the complex dynamics within family businesses and underline the need to address gender disparities and promote inclusive Ownership practices. Implications are discussed. [ABSTRACT FROM AUTHOR]

Inequality is a problem that remains latent throughout generations, despite the growth of countries and the mechanisms that were implemented to mitigate it. Understanding the structure of spillovers from a spatial point of view would allow for the management of current resources, with the aim of improving the distribution among individuals at the cantonal level for Ecuador. In this context, this study aims to estimate the effect of the determinants of income inequality at the cantonal level, through the use of spatial models during the period 2010–2019, for 213 cantons in Ecuador. The Kuznets inverted-U theory is applied, which allows us to understand the changes that economic growth produces on income inequality levels. The approach indicates that the current average rate of growth of production per capita has made inequality levels decrease. In addition, human capital has the opposite effect to that expected, increasing inequality levels as a result of a concentration of this resource in certain cantons. On the other hand, the entrepreneurial structure of micro and small enterprises allows to mitigate the inequality levels between cantons. In this sense, among the policy objectives is to prioritize a more homogeneous growth of the cantons of Ecuador, likewise, generate policies that allow reducing the concentration of human capital in certain regions, as well as financial development. On the other hand, it is important to strengthen the prevalence of Micro, small and medium-sized enterprises in the long term, with the aim of improving family income levels and reducing inequality.

Ensuring the integrity of the world’s forests is indispensable for mitigating climate change, combatting biodiversity loss, and protecting the livelihoods of rural communities. While many strategies have been developed to address deforestation across different geographic scales, measuring their impact against a fluctuating background of market-driven forest loss is notoriously challenging. In this article, we (1) asses deforestation in Ecuador using a dynamic, counterfactual baseline that excludes non-market factors, (2) identify periods of reduced and excess deforestation, and (3) assess the economic consequences of associated CO2 emissions using the social cost of carbon metric. We construct a counterfactual market-forces-only reference scenario by simulating heterogeneous profit-seeking agents making satisficing land-use allocation decisions under uncertainty. The model simulates a reference scenario for 2001–2022, a period encompassing dollarization, the beginning of a constitution granting inalienable rights to nature, and the launch of the largest payments for ecosystem services program in Ecuador’s history. On this period, total deforestation was approximately 20% lower than expected in a market-forces-only scenario (9540 vs.12,000 km2). The largest deviation occurred in 2001–2009, when observed deforestation was 43.6% lower than expected (3720 vs 6590 km2). From 2010 onwards, deforestation appears to be market-driven. We assess the economic value of avoided CO2 emissions at US $5.7 billion if the reduction is permanent, or US $3.1 billion considering a 1% risk of loss from 2022 onwards. We discuss contributing factors that likely shaped periods of reduced and excess deforestation and stress the need to use realistic baselines. [ABSTRACT FROM AUTHOR]

Internationalisation is a way for companies' growth and economic development in transition economies with the potential to contribute to a more sustainable world. Social and solidarity economy cooperatives (SSECs) have a lower internationalisation trend than developed economy companies due to their aversion to possible economic losses and lack of knowledge of the global market. This study aims to propose an internationalisation model for non-financial SSECs through factor analysis and evolutionary genetic computing to improve structural competitiveness within the framework of sustainable development in an emerging country. The study methodology includes: (1) information analysis related to internationalisation indicators; (2) statistical analysis of variables from the national survey of popular and solidarity economy organisations; (3) internationalisation model through a genetic algorithm; and (4) strategies related to sustainability. The results show internationalisation models with significant indicators such as number of partners, social capital, social benefit, access to international markets and employment. These models have goodness of fit with a high degree of precision (> 80%) and are a novel proposal to estimate the internationalisation of social capital cooperatives. [ABSTRACT FROM AUTHOR]

In this paper, we introduce a notion of mergeable weighted majority games with the aim of providing the first characterization of the Colomer–Martínez power index (Colomer and Martínez in J Theor Polit 7(1):41–63, 1995). Furthermore, we define and characterize a new power index for the family of weighted majority games that combines ideas of the Public Good (Holler in Polit Stud 30(2):262–271, 1982) and Colomer–Martínez power indices. Finally, we analyze the National Assembly of Ecuador using these and some other well-known power indices. [ABSTRACT FROM AUTHOR]

This paper describes and analyzes phonological processes pertinent to the glottal stop in A'ingae (or Cofán, iso 639-3: con). The operations which the glottal stops undergo and trigger reveal an interaction of two morphophonological parameters: stratum and stress dominance. First, verbal suffixes are organized in two morphophonological domains, or strata. Within the inner domain, glottal stops affect stress placement, which I analyze as an interaction with foot structure. In the outer domain, glottal stops do not have any effects on stress. Second, some verbal suffixes delete stress (i. e. they are dominant). Dominance is unpredictable and independent of the suffix's morphophonological domain, but dominance and the phonological domain interact in a non-trivial way: only inner dominant suffixes delete glottalization. To account for the A'ingae data, I adopt Cophonologies by Phase (Sande et al. 2020), which (i) models phonological stratification while (ii) allowing for morpheme-specific phonological idiosyncrasies, which (iii) interact with the phonological grammar of their stratum. Stress deletion triggered by the dominant suffixes is modeled with AntiFaithfulness (Alderete 1999, 2001). Antifaithfulness to a metrical foot entails antifaithfulness to its features (glottalization). This captures the fact that only the inner dominant suffixes delete glottal stops.

The present study examined how conspiracy beliefs about COVID-19 vaccines specifically relate to symptoms of fear of COVID-19 in a sample of four South American countries. A total of 1785 people from Bolivia, Colombia, Ecuador, and Peru participated, responding to a sociodemographic survey, the Fear of COVID-19 scale (FCV-19 S) and the Vaccine Conspiracy Beliefs Scale-COVID-19 (VCBS-COVID-19). Network analysis identified the most important symptoms of fear and conspiracy beliefs about COVID-19 vaccines (nodes) and the associations between them (edges). In addition, the robustness of the network of these indicators of centrality and the possible differences in the structure and connectivity of the networks between the four countries were evaluated. The results suggest that the nodes with the highest centrality were items 2 and 5 of the FCV-19 S and item 2 of the VCBS-COVID-19. Likewise, item 6 is the belief that most predicts conspiracy beliefs about vaccines against COVID-19; while item 6 was the symptom that most predicts fear of COVID-19. The findings strongly support cross-cultural similarities in the networks across the four countries rather than differences. Although it was expected that a higher presence of symptoms of fear of COVID-19 may lead people to compensate for their fear by believing in conspiratorial ideas about vaccines and, consequently, rejecting the COVID-19 vaccine, the results do not clearly show this relationship. This could lead other researchers to generate evidence to explain the differences between Latin American countries and countries in other contexts in terms of vaccination rates. This evidence could be useful to develop policies favoring vaccination against COVID-19 that are more contextualized to the Latin American region, characterized by social instability and economic recession during the pandemic.

We report, in 15 Ecuadorian mountainous lakes, dissolved concentrations of CO2, CH4, and N2O and a suite of ancillary biogeochemical variables (dissolved inorganic nutrients, oxygen, major cations, dissolved and particulate organic carbon, and the stable isotope composition of dissolved inorganic carbon and water). The sampled lakes were located in the páramos of Salve Facha and Antisana y Mojanda (northern region of Ecuadorian Andes), along an elevational gradient from 2213 to 4361 m above sea level, as well as a gradient of lake surface area (0.003–6.1 km2) and depth (1–74 m). Most lakes were characterized by lower values of the partial pressure of CO2 (pCO2) (644–2152 ppm) than usually attributed to tropical lakes (~ 1900 ppm). Three lakes influenced by volcanic inputs were characterized by the highest pCO2 values (3269–10,069 ppm), while two lakes bordered by large cities were characterized by the lowest pCO2 values (208–254 ppm). Dissolved CH4 concentrations ranged between 170 and 24,908 nmol/L and were negatively correlated to lake area and depth. N2O saturation levels ranged between 64% and 101%. The surface waters were undersaturated in N2O with respect to atmospheric equilibrium, probably due to inputs of soil–water with low N2O levels owing to denitrification in soils. The data obtained in the sampled highland lakes was combined with published data from lowland lakes (elevation < 500 m, n = 17 for CO2 and n = 16 for CH4) to derive relations between CO2 and CH4 and lake surface area, allowing to compute CO2 and CH4 lacustrine emissions at the scale of the Amazon basin using the HydroLAKES spatial data set. The CO2 and CH4 emissions from highland lakes (elevation > 500 m) only represented 0.4% and 2% of the total lacustrine emissions at the scale of the Amazon basin, respectively. Total CO2 and CH4 emissions from lakes represented a small fraction (8.6%) of total lentic and lotic CO2 and CH4 emissions at the scale of the Amazon basin. The lake and river emissions of CH4 represented ~ 3% of total CH4 emissions from all compartments of the Amazon basin, mainly attributable to wetlands. [ABSTRACT FROM AUTHOR]

Sustainable development goals (SDGs) include ensuring the availability and sustainable management of water and sanitation. Although countries have made significant progress in achieving this goal, many nations in the world still lack access to safe drinking water. For example, in Latin America and the Caribbean, 161 million people (one in four) do not have adequate access to safe drinking water (ECLAC 2022). Despite these figures, no studies in the region have analyzed the factors that explain the probability that families have access to safe drinking water. It is crucial for governments to implement comprehensive public policies to address this multidimensional problem. Therefore, this study aimed to provide evidence of the most important factors that explain the probability of families in a developing country (Ecuador) to have access to safe water. Family income, education of the household head, type of housing tenure, type of water supply and source, area of residence (urban or rural), and the natural region where the family is located are significant variables that condition access to safe water. At the end of the document, we discuss the policy actions at length. [ABSTRACT FROM AUTHOR]

In Ecuador, the main tick species affecting cattle are Rhipicephalus microplus and Amblyomma cajennense sensu lato. Understanding their spatial distribution is crucial. To assess their distribution, data from 2895 farms visited between 2012 and 2017 were utilized. Ticks were collected during animal inspections, with each farm's location georeferenced. Bioclimatic variables and vapor pressure deficit data were obtained from Climatologies at High resolution for the Earth´s Land Surface Areas (CHELSA) dataset. They were overlaid to develop predictive maps for each species using Random Forest (RF) models. The cross-validation results for RF prediction models showed high accuracy for both R. microplus and A. cajennense s.l. presence with values of accuracy = 0.97 and 0.98, sensitivity = 0.96 and 0.99, and specificity = 0.96 and 0.93, respectively. A carefully selected subset of bioclimatic variables was used to describe the presence of each tick species. Higher levels of precipitation had positive effect on the presence of R. microplus but a negative effect on A. cajennense s.l. In contrast, isothermality (BIO3) was more important for the presence of A. cajennense s.l. compared to R. microplus. As a result, R. microplus had a broader distribution across the country, while A. cajennense s.l. was mainly found in coastal areas with evident seasonality. The coexistence of both species in some regions could be attributed to transitional zones, whereas high altitudes limited tick presence. This information can aid in developing appropriate tick management plans, particularly considering A. cajennense s.l.'s broad host range species and R. microplus's specificity for cattle. Moreover, the predictive models can identify areas at risk of associated challenging hemoparasite, requiring special attention and mitigation measures. [ABSTRACT FROM AUTHOR]

By means of probabilistic graphical models, in this paper, we present a new framework for exploring relationships among indicators commonly included in the Multidimensional Poverty Index (MPI). In particular, we propose an Ising model with covariates for modeling the MPI as an undirected graph. First, we prove why Ising models are consistent with the theoretical distribution of MPI indicators. Then, a comparison between our estimates and the association measures typically used in the literature is provided. Finally, we show how undirected graphs can complement the MPI policy-relevant properties, apart from discovering further insightful patterns that can be useful for policy purposes. This novel approach is illustrated with an empirical application for the global MPI indicators of Guinea and Ecuador, taking living areas and monetary poverty as covariates, respectively.

Although several brands of tuberculin purified protein derivatives (PPDs) are available for diagnosing bovine tuberculosis (bTB), comparative studies to determine their diagnostic accuracy are infrequent. In Ecuador we compared two different PPD brands for bTB diagnosis using skin testing and measuring skin thickness increase. Additionally, we evaluated four PPD brands, including those used for skin testing, in the Bovine Tuberculosis Interferon Gamma Test (IFN-γ test) measuring IFN-γ induction in whole blood. The study included 17 naturally tuberculosis-infected PPD and IFN-γ test positive bovines. Both the field and laboratory results showed significant differences in classifying the 17 bovines as bTB positive or negative. We hypothesize that several factors, such as the genetic background of the cows, sensitization to environmental mycobacteria, M. bovis strains involved in the bTB infection, and the manufacturing procedures of the PPDs, could have influenced the immune reaction toward the different tuberculin PPD brands. Our study emphasizes the necessity for comparative studies aimed at determining the diagnostic accuracy of PPD brands for bTB diagnosis as well as the development of standardized methods for PPD production and potency determination.

How, if at all, does self-interest bear on individuals' economic policy preferences? Though conventional theories of preference formation usually assume a role for self-interest, the informational demands associated with understanding economic policies can prevent individuals from forming attitudes on an egocentric basis. Building on work showing that policy-specific information facilitates egocentrism, we argue that personal experience with alternative policy options is necessary for self-interested preferences to materialize. To test this argument, we leverage Ecuador's adoption of the U.S. dollar (i.e., dollarization) and examine whether material-based preferences toward exchange rate policy are conditional on individuals experiencing the transition from the Ecuadorian sucre to the dollar. We find that lived experience with dollarization causes policy preferences to align more closely with citizens' self-interest, as proxied by measures of capital ownership and skill level. In addition, personal experience with dollarization drives attitudes against a dollarized economy, but primarily among poor and low-skill workers—precisely the groups that benefit less from this policy shift. Rather than entirely discredit the role of economic self-interest, these findings suggest that scholars devote greater attention to how contextual factors can strengthen egocentric policy attitudes.

The province of Chimborazo located in the northern Andes of Ecuador presents many intrinsic factors, which contribute to the occurrence of mass movements, leaving in many of the cases registered damages of materials and loss of life. The recent landslide of March 26, 2023, in the Alausí canton is an event of great interest due to the magnitude of the occurred destruction and the corresponding fatalities. Therefore, there are two predominant objectives of the current study, of which the first has been to determine the most relevant characteristics of this mass movement by identifying and analyzing the geomorphology of the recorded slope movement and the lithological units involved, by field work and through geophysical surveys. Secondly, we performed a preliminary study of the possible triggers of the movement by means of the historical analysis of the precipitations during the months of January to March of the last decade and the study of the recent seismic series. However, through the obtained analysis, it is determined that the study site is composed of three distinctive lithological units. The observed mass movement is of the rotational type, as result of the intense rainfall that occurred during the first quarter of 2023, being hereby the most probable triggering factor. This corresponds to a 600% increase in the average monthly rainfall compared to the period from 2010 to 2022. [ABSTRACT FROM AUTHOR]

The CONIAE (Confederation of Indigenous Nationalities of Ecuador) continuously critiques the global capitalist neoliberal structure. Similarly, this Indigenous critique is embodied in the projects studying the past in the Ecuadorian territory, particularly in the research of the gendered/sexual relations of the Enchaquirados during the pre-Hispanic period. This article builds upon this ethnohistorical research to show how these noncapitalist forms of economic, political, and gendered/sexual relationships continued to develop and evolve alternative forms of agency, livelihood and resistance. In Engabao (one of Ecuador's many rural coastal communities), like in the CONAIE'S discourse, these cultural alternatives to the capitalist system tie this historical past to an agent-filled resistant Indigenous political present.

Energy consumption is a crucial driver for economic development, improving the quality of life of the population of a country. This study attempts to contribute to the discussion by employing a systemic approach and methodology to examine the relationship between energy consumption (EC), gross domestic product (GDP) and carbon dioxide emissions (CO2) in Ecuador using time series from 1990 to 2018 with a mixed methodology (quantitative and qualitative). The energy balance and the enlarged Kaya identity are utilised to quantify the environmental impact of human activities. Furthermore, correlational cointegration and Granger causality tests are used to analyse the long-term and short-term relationships between variables in different sectors. The results reveal that there is no Granger causality between the variables in the agriculture and transport sectors, but there are unidirectional causality relationships in the industry and services sectors. In the industry sector, the study finds that EC Granger causes GDP (Wald test p value = 0.0038) and CO2 Granger causes GDP (Wald test p value = 0.0433). In the services sector, GDP Granger causes CO2 (Wald test p value = 0.0075), and EC Granger causes CO2 (Wald test p value = 0.0122), reinforcing the loop between GDP and CO2 in both the sectors. The analysed relationships help to inform policymakers about the likely impact of interventions. In addition, the study shows that Ecuador is in the initial phase of the Environmental Kuznets Curve, and provides strategies to manage sectoral energy consumption and valuable insights for other developing countries in Latin America seeking to pursue sustainable development.

In the light (or in the darkness) of the current climate and energy crises, a future in which the extraction of carbon-based fuels is phased down sounds less utopian, though still an upward struggle in an international context shaped by mainstream technoeconomic narratives. Concepts like "unburnable carbon," or the idea that fossil fuel reserves would need to remain under the ground in order to comply with the Paris Agreement, become prominent, and research on supply-side climate policy aimed at limiting further expansion of fossil fuel extraction gains momentum. Yet, there has been scarce attention so far to the role of supply-side approaches in building an equitable and just energy transition. With a view to filling this gap, in this contribution I build on the insights of Ecuador, a quintessential example of a natural resource-dependent country in the Global South and revisit the widely discussed Yasuní initiative, a pioneering international cooperation scheme to leave oil reserves in the ground, which is again topical due to the referendum of 2023. On the one hand, I argue that the energy transition underway imposes additional challenges when thinking about decarbonizing the energy sector and the national economy in a country, which traditionally followed a natural resource-driven development path. On the other hand, I discuss the social and political arrangements that surround the results of the referendum on stopping oil extraction in the Yasuní national park in the Ecuadorian Amazon region. With the insights of Ecuador, I finally intend to shed light on social, political, and international conditions needed for innovative supply-side projects to succeed in natural resource-rich countries in the Global South.

The present study identifies the most influential industries in Ecuador according to the Input–Output Table for 2019. For this purpose, four weighted centrality indices are used from Social Network Analysis: Degree Centrality, Closeness Centrality, Betweenness Centrality, and Alpha Centrality. The results suggest that wholesale and retail trade, transportation, and professional activities are the most influential in the Ecuadorian economy due to their high centrality in commercial relationships. According to Chenery and Watanabe's methodology, all are base sectors, that is, they mainly are supply-driven. So, these centrality measures highlight the relevance of sectors based on their forward linkages. This result is not surprising. The theory of shock diffusion suggests that productive shocks on high centrality sectors can spread cascading effects downstream and generate aggregate fluctuations. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic generated diverse impacts and responses in agricultural value chains worldwide. Cocoa is a key crop for Ecuadorian exports, and the analysis of effects the pandemic had on value chain actors contributes to the understanding of their individual capacities to coping with a major shock. The purpose of this study was to assess the number and severity of impacts and responses implemented by two links in the cocoa value chain to the pandemic, based on a survey of 158 cocoa farmers and 52 cocoa intermediaries from the main cocoa-producing provinces of the northern coast of Ecuador in 2021. Surveyed farmers and part of the intermediaries form part of the sustainability program of a large Swiss chocolate manufacturer. The impacts and responses reported were grouped into seven resources according to the Activity System Approach. Then, a comparison between groups was applied using the Wilcoxon rank sum test for nonparametric data, determining the most severe impacts and effective resilience responses among the actors. The results reveal that farmers and intermediaries were similarly affected by the pandemic, reporting 21 and 16 negative impacts, respectively. Farmers experienced a higher number and severity of impacts on financial and social resources, while intermediaries on human and material resources. The strongest impact was the loss of sales, reported by 65% of farmers and 58% of intermediaries. Farmers implemented more social responses that they judged highly effective, while intermediaries implemented more human responses that they judged highly effective. Public policy should enhance the social resources of farmers by strengthening their associativity and the capacities of their members, as mechanisms to mitigate their vulnerability to future health and climate crises. The financial resources of both actors should be protected through public credit and agricultural insurance. [ABSTRACT FROM AUTHOR]

Wildlife conservation in Andean countries is a global priority because of the high levels of biodiversity and endemism. Historically, these countries have had limited resources to monitor wildlife (e.g., through genetic tools) and establish conservation programs. Focusing on the study and emblematic use of a few charismatic species has been a strategic approach to direct efforts for conservation and development planning. Consequently, the Andean bear is a flagship and umbrella species for highly biodiverse Andean countries like Ecuador. The few studies exploring the population genetics of this species have concluded that it has low genetic diversity and few units for conservation as populations appear to be well connected. However, these results might be attributed to ascertainment bias as studies have been performed with heterologous molecular markers. Here, using both mtDNA sequences and species-specific microsatellite markers, we show that Andean bears in Ecuador have population structure. Additionally, we found through the study of three Ecuadorian populations that the species might have a higher genetic diversity than we previously thought. These results could support the revision of research priorities, conservation, and planning strategies to improve connectivity for this species which occurs in crucial biodiversity hotspots.

The impacts on food prices of temperature, the oil price, the exchange rate and wages in the agricultural industry were examined via a structural vector autoregression model and panel Granger causality test, using monthly data between January 2003 and December 2020 for Latin American countries. The paper concerns how much the determinants affect food prices. Empirical findings show that the oil price and temperature can be significant factors for reducing food inflation. According to the result of variance decomposition, in general, a considerable part of food inflation was explained by the exchange rate, but its effect did not show any significant change in the long term. The impacts of the oil price and temperature were limited in the early months, but they created larger changes over time. Impulse response function and the Granger causality test also indicated that exchange rate was a crucial dynamic in explaining food inflation in all countries except Ecuador. This country successfully mitigated the negative effect of the exchange rate, but the oil price and temperature had an impact on food inflation. All results indicate that both monetary and fiscal policies are essential to control food prices. These countries can accomplish this by conventional policies or by radical institutional changes. Nevertheless, the oil price and temperature are external dynamics, and crucial in creating alternative policies to control food inflation. [ABSTRACT FROM AUTHOR]

We use information from the electronic billing system to estimate the underreporting of income of private sector employees. We follow an expenditure-based methodology using the consumption of public and private sector employees for similar levels of reported income. We find that private sector employees underreport between 7 and 9% of their income in Ecuador. The size of the underreporting gap is negatively correlated with the number of employees at the firm, consistent with different risks and administrative costs of 'envelope wages' in small versus large firms.

Chronic hydrocarbon spills are a threat to coastal ecosystems, and their impact on the water quality along watercourses should be characterised to medium long term in order to assess the risk and define cost-effective and sustainable remediation strategies. For this purpose, a methodology for the measurement of total petroleum hydrocarbons (TPH) on a spatio-temporal scale was designed, implemented and validated in the Punta Carnero estuary, in the Santa Elena province, western Ecuador, which is affected by hydrocarbon pollution. The selection of monitoring stations was made according to the different inflows along the water system corresponding to the different anthropogenic activities in the area, in order to assess whether the effluents involve critical levels of pollution. Measurements of hydrodynamic, environmental and vegetation cover parameters were also carried out to assess their possible variations as a consequence of the impact of the spatio-temporal TPH concentrations. An increase in hydrocarbon concentrations was observed from 2013 to 2021. Mean annual TPH levels were above the maximum allowable limit for the protection of aquatic and other wildlife in estuarine waters according to the Ecuadorian regulation for environmental quality. An increase in mangrove tree cover could contribute to an exponential decrease in contamination levels. The methodology used in this study may support the quantifying of TPH content in future applications, which is a priority task for the restoration of degraded ecosystems. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic's early stages severely impacted global fisheries, particularly areas heavily reliant on imported food and tourism like the Galapagos Islands, Ecuador. To contain the spread of the virus, a full lockdown was implemented. However, the collapse of the tourism industry precipitated the worst economic crisis in the history of this multiple-use marine protected area. This paper examines the impact of the pandemic's early stages on consumption patterns and seafood security in the Galapagos from consumers' perspective, drawing on online surveys conducted during the lockdown. Our findings revealed pre-existing seafood insecurity across the archipelago, further exacerbated by the pandemic on the least-populated island. Nevertheless, the seafood system displayed moderated resilience to the pandemic's socioeconomic disruptions. A variety of adaptive responses were adopted by Galapagos residents to cope with the lockdown. Consumers modified their seafood consumption habits, while fishers adapted their harvesting and marketing strategies. Such adaptive responses were shaped by the unique socioeconomic characteristics of each inhabited island and the ability of seafood suppliers to shift from a tourism- and export-oriented to a resident- and domestic-oriented market. This transition has created novel opportunities to foster a systemic transformation of the Galapagos seafood system to enhance its resilience against future crises caused by new pandemics, climate change, or other natural and anthropogenic drivers of change.

In recent years, several studies have shown that the incidence of buying-shopping disorder (BSD) is increasing. Impulsivity is one of the factors involved in its aetiology and is related to emotional dependence. In addition, early affective deprivation may trigger emotional dependence. The aims of the present study weresal: to compare the types of attachment, levels of emotional dependence, impulsivity and BSD according to sex; to determine whether the proposed relational model is fulfilled; and analyse possible differences in this model in terms of the sample's sex. The sample consisted of 1498 adolescents (53.8% men and 46.2% women) from Ecuador whose age ranged from 14 to 18 years (M = 15.77, SD = 1.21). The results showed that a preoccupied attachment style is indirectly related to a higher risk of BSD due to emotional dependence when impulsivity levels are medium or high because emotional dependence is moderated by impulsivity. The study variables are related in the same way in men and women but boys show higher levels of preoccupied attachment, impulsivity, emotional dependence and BSD. This study gives us a clearer picture of how these variables are related and provides information that could be of great use in assisting people with BSD. This knowledge could be applied to improve both the treatment and prevention of this problem. [ABSTRACT FROM AUTHOR]

Here, we present BASD-CMIP6-PE, a high-resolution (1d, 10 km) climate dataset for Peru and Ecuador based on the bias-adjusted and statistically downscaled CMIP6 climate projections of 10 GCMs. This dataset includes both historical simulations (1850–2014) and future projections (2015–2100) for precipitation and minimum, mean, and maximum temperature under three Shared Socioeconomic Pathways (SSP1-2.6, SSP3-7.0, and SSP5-8.5). The BASD-CMIP6-PE climate data were generated using the trend-preserving Bias Adjustment and Statistical Downscaling (BASD) method. The BASD performance was evaluated using observational data and through hydrological modeling across Peruvian and Ecuadorian river basins in the historical period. Results demonstrated that BASD significantly reduced biases between CMIP6-GCM simulations and observational data, enhancing long-term statistical representations, including mean and extreme values, and seasonal patterns. Furthermore, the hydrological evaluation highlighted the appropriateness of adjusted GCM simulations for simulating streamflow, including mean, low, and high flows. These findings underscore the reliability of BASD-CMIP6-PE in assessing regional climate change impacts on agriculture, water resources, and hydrological extremes. [ABSTRACT FROM AUTHOR]

The Instituto Geofísico (IG-EPN) was created in 1983 by faculty of the Escuela Politécnica Nacional, a public university in Quito, Ecuador, with the objective of assessing volcanic hazard in the country. Since then, the IG-EPN has established and developed an instrumental monitoring network and from 1999 has faced the eruption of five continental-arc volcanoes (Guagua Pichincha, Tungurahua, Reventador, Cotopaxi, and Sangay) which displayed varied hazards, eruptive dynamics, eruption durations, and socio-economic contexts. At the same time, mainly effusive eruptions took place in Galápagos archipelago, which has undergone an increase in local population over the last two decades and hence in the risk posed by volcanic eruptions. The outstanding handling of these volcanic crises was the reason why IG-EPN was granted with the 2020 Volcanic Surveillance and Crisis Management IAVCEI Award. Now, the IG-EPN manages a country-wide network of about 500 instruments to monitor both volcanic and tectonic activity with a highly qualified staff of 80 people. This manuscript describes the history of IG-EPN, the main volcanic hazard studies and resulting hazard maps; the instrumental networks; and the volcanic crises that the IG-EPN faced during the last forty years.

Positive parenting and appropriate interaction with children are globally recognized as pivotal in enhancing children's quality of life. Evaluating family intervention programs is therefore vital, particularly in regions that lack reliable tools for assessment. This manuscript details a study conducted in Ecuador, a country noted for its scarcity of validated instruments to assess the impact of such interventions, especially for vulnerable preschool children. We focused on the application of the North Carolina Family Assessment Scale (NCFAS), a well-established measure to evaluate family functioning internationally, to Ecuadorian families with preschool children who are deemed vulnerable. The Spanish translation of the original scale was administered by trained evaluators to 470 preschool children in Machala, Ecuador. Our examination of the psychometric properties of the NCFAS in this context demonstrated high internal consistency. Additionally, factor analysis corroborated the reliability and validity of this adapted version of the NCFAS, albeit with a reduced item count. This research supports the effectiveness of the NCFAS in the Ecuadorian setting and underscores its potential utility in further studies involving varied demographic groups within the country. The results of this study have substantial implications for the enhancement of children's quality of life in Ecuador through family intervention programs. Highlights: The Ecuadorian study used the NCFAS to assess 470 vulnerable preschoolers' environments. High internal consistency and reliability were confirmed in this context. The adapted version with fewer items was validated through factor analysis. The results are pivotal for designing interventions in areas lacking reliable tools. [ABSTRACT FROM AUTHOR]

The length and steepness of the slope (LS-Factor) describe the role that topography plays in the hazard of soil erosion and constitutes one of the five factors that allow the determination of soil loss using the Revised Universal Soil Loss Equation (RUSLE) mathematical model. This factor is calculated using Digital Elevation Models (DEM); however, its spatial scale may affect the quality of its estimation. The objective of the present investigation was to analyze the sensitivity of the DEM spatial resolution in the calculation of RUSLE LS-Factor and to determine its implications in the estimation of soil erosion rates in Ecuadorian basins. The methodology considered the delimitation of the hydrographic basins and the evaluation of data from SRTM, HydroSHEDS and ALOS PALSAR as providers of DEMs databases through the implementation of two statistical methods. The delimitation of the basins was obtained from the regional literature and the DEMs databases from web servers. Comparisons of the results at the national scale and at the basin scale were established using the original spatial scales and a common scaling of 1 and 4 km. The results will make it possible to determine the most appropriate spatial scale of DEM database to determine soil erosion rates considering the particular conditions of the study area, applying the RUSLE model.

Shrimp production is an important industry for many countries and shrimp consumption is increasing worldwide. Shrimps are a highly nutritional food, but can pose a risk for human health if subject to high levels of environmental contaminants. This work studies the presence of As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn in shrimps from Ecuador and compares them to such contents noted in other shrimp-production areas in the world to evaluate the possible risks associated with these elements for consumer health, and to relate them to potentially toxic element (PTE) contents in water, sediments and diets, and also to animal biometric parameters. The PTE levels (mg kg−1 DM) obtained are as follows: in the head—As (3.52–6.11), Cd (0.02–0.10), Co (0.14–0.49) Cr (0.23–4.89), Cu (99.9––233.0), Ni (0.52–1.86), Pb (0.24–1.09), Zn (51.8–100.5) and Hg (μg kg−1 DM) (10.00–66.81); in the tail—(0.91–3.21), Cd (0.01–0.02), Co (0.01–0.43) Cr (0.01–6.52), Cu (20.0–72.44), Ni (0.15–2.03), Pb (0.01–0.69), Zn (31.2–66.1) and Hg (μg kg−1 DM) (10.00–67.18). The concentration of all the PTEs is generally lower than the limits set for seafood by European regulations, except for As in the cephalothorax (4.63 mg kg−1). Different behaviours for PTE accumulation in shrimps were found, which preferentially tend to accumulate in the cephalothorax, except for Hg (40.13 μg kg−1 DM), which accumulates in muscle (body) and is associated with contents of proteins, lipids and total shrimp weight. Nonetheless, the target hazard quotient (THQ) values for PTEs indicate that the consumption of shrimp muscles from Ecuador does not pose a human health risk because the values of these indices are below 1 in all cases.

When men migrate from Venezuela for survival, they bring with them a forming political self related to local daily encounters with threatening political practices in their country of origin and through transit countries. The political self is formed in interpersonal interactions in the pursuit to sustain life even as trust has been eroded. Increased attention to lived experience within survival migration brings together migration studies, political science, and psychodynamic theories related to violence and trust. Drawing from pastoral care encounters in Ecuador, the article provides a nascent construct on the political self that influences men in terms of their own sense of care, responsibility, and personhood.

A new species of Aiouea (Lauraceae) from the Colombian Andes is described and illustrated. Aiouea chicaque is distinguished by the following combination of characters: elliptic leaves with cuneate to attenuate bases, pinnate venation, glabrous, without domatia, externally glabrous flowers with stamens of whorls I and II with four locules, whorl III with two locules, and fruits with persistent tepals in the cupule. According to IUCN criteria, the new species is given a preliminary threat assessment as Vulnerable (VU) based on its reduced area of occupancy and the small number of localities where it is found. Additionally, two species of Ocotea and one of Andea, previously known from the Andes of Ecuador, are here recorded for the first time for the flora of Colombia: O. fistulosa, O. pautensis and A. homeieri.

The idea that not all types of consumption benefit well-being is not new. However, its recent formalization within the framework of the behavioral and social sciences has led to a rapid expansion of knowledge about the goods that are most effective in increasing happiness. Most evidence has been obtained from the developed world and with a focus on broad categories that ignore meaningful heterogeneities. This paper contributes to this domain by conducting a detailed analysis of the relationship that happiness has with a variety of market goods and with aggregate measures of purchasing power. We do this using the data of Ecuador, a country characterized by a relational-oriented culture, high collectivist values, structural inequalities, and weak political institutions. Throughout the paper, we tested various hypotheses related to this particular context. The results show that consumption is superior to income as a predictor of happiness. Higher levels of happiness can also be seen among people who spend more on relational and time-saving goods; less on health and alcohol; and own a good quality of dwelling. As for basic goods, some seem beneficial in the whole sample analysis, but they exhibit a stronger relationship with happiness among the poor. Additionally, we find that, in most cases, public goods as well as paying taxes correlate negatively with happiness. Moreover, we identify some heterogeneities that shed light on the behavior of the poor and that reflect unequal distribution of household tasks. [ABSTRACT FROM AUTHOR]

Vereda is a wetland ecosystem typical of the Cerrado biome characterized by diverse vegetation with dynamic and transitional areas of riparian forests, gallery forests, flooded forests, and humid grassland. In general, they are associated with controlling the flow of the water table, carbon storage, and high biodiversity and are essential to the maintenance of most rivers in the Cerrado biome. Besides that, Vereda is poorly studied, especially zooplanktonic groups. To lessen this knowledge gap, we evaluated the effects of seasonality and environmental predictors on the zooplanktonic community of Vereda. For that, we sampled zooplanktonic assemblages in the Veredas in the dry and wet seasons. We found environmental influence but not for the zooplankton community. The characteristic low conductivity seems to be an important environmental filter for zooplankton species occurrence in these systems, since the Veredas that registered major levels of richness and density were those with high electrical conductivity. Highlighting that some zooplankton species with a more restricted distribution were detected in this study: Acroperus tupinamba, which occurs in Brazil and Ecuador; Monospilus sp., for which only two species of this genus were registered in Brazil, both with restricted distribution, found thus far in only two protected areas of the Cerrado biome.

Marine sediments are a useful environmental assessment matrix as they naturally trap toxic substances of anthropogenic origin and thus have higher concentrations of these than the surrounding water. Therefore, developing methods for the sensitive, accurate, and inexpensive quantification of these substances is important, as the traditional techniques have various disadvantages. The current study evaluated the effectiveness of an in situ bismuth-modified carbon-fiber microelectrode (voltamperometric sensor) to simultaneously detect Pb, Cd, and Zn in marine sediments from Puerto Jeli in El Oro Province, Ecuador. This site is representative of the contamination levels present along the coast in this province. Differential pulse anodic stripping voltammetry was applied, and the resulting linear regression for the metal quantification ranged from 12 to 50 μg mL−1, with quantification limits for Pb(II), Cd(II), and Zn(II) of 18.69, 12.55, and 19.29 μg mL−1, respectively. Thus, the quantification with the sensor was successful. According to the preliminary results, Cd and Pb values exceeded the permissible limits established by Ecuador (Texto Unificado de la Legislación Secundaria del Ministerio del Ambiente) and the US Environmental Protection Agency, respectively.

Tropical forest recovery is fundamental to addressing the intertwined climate and biodiversity loss crises. While regenerating trees sequester carbon relatively quickly, the pace of biodiversity recovery remains contentious. Here, we use bioacoustics and metabarcoding to measure forest recovery post-agriculture in a global biodiversity hotspot in Ecuador. We show that the community composition, and not species richness, of vocalizing vertebrates identified by experts reflects the restoration gradient. Two automated measures – an acoustic index model and a bird community composition derived from an independently developed Convolutional Neural Network - correlated well with restoration (adj-R² = 0.62 and 0.69, respectively). Importantly, both measures reflected composition of non-vocalizing nocturnal insects identified via metabarcoding. We show that such automated monitoring tools, based on new technologies, can effectively monitor the success of forest recovery, using robust and reproducible data. Cost-effective biodiversity monitoring through time is important for evidence-based conservation. Here, the authors show that automated bioacoustics monitoring can be used to track tropical forest recovery from agricultural abandonment, suggesting its use to assess restoration outcomes.
