The Brazilian Amazon faces three dominant governance challenges that have become increasingly interconnected over time and now affect each other: managing agricultural expansion, reducing deforestation, and mitigating urban floods. This region exemplifies that the governance of one social-ecological system (SES) in the Anthropocene can no longer be thought of in isolation of others because, together, they form a complex network of flows and spillovers to manage. Studying the interconnection of different decision-making areas, however, calls for an intertemporal examination of governance that integrates different methodological approaches. We use the Network of Adjacent Action Situations (NAS), Combined IAD-SES (CIS) framework, and the telecoupling framework to study these three interrelated processes in the Amazon. Employing mixed-methods research, including fieldwork covering each of these processes, we demonstrate how the governance of multiple SESs represents an intertemporal governance challenge. Our paper contributes to the SES governance and NAS literature by linking governance issues generally looked at separately and offering an understanding of the governance connections between telecoupled processes. Beyond its contribution to Brazilian Amazon governance, this paper offers an integrated framework that may be useful to study the interconnection of governance of NAS in other places.

Forests serve a crucial role in our fight against climate change. Secondary forests provide important potential for conservation of biodiversity and climate change mitigation. In this paper, we explore whether collective property rights in the form of indigenous territories (ITs) lead to higher rates of secondary forest growth in previously deforested areas. We exploit the timing of granting of property rights, the geographic boundaries of ITs and two different methods, regression discontinuity design and differencein-difference, to recover causal estimates. We find strong evidence that indigenous territories with secure tenure not only reduce deforestation inside their lands but also lead to higher secondary forest growth on previously deforested areas. After receiving full property rights, land inside ITs displayed higher secondary forest growth than land outside ITs, with an estimated effect of 5% using our main RDD specification, and 2.21% using our difference-in-difference research design. Furthermore, we estimate that the average age of secondary forests was 2.2 y older inside ITs with secure tenure using our main RDD specification, and 2.8 y older when using our difference-indifference research design. Together, these findings provide evidence for the role that collective property rights can play in the push to restore forest ecosystems. [ABSTRACT FROM AUTHOR]

A regional approach to the study of Brazil's beef industry is increasingly relevant as deforestation takes centre stage in policy debates worldwide. To what extent has beef production expanded toward regions hosting sensitive ecosystems such as the Amazon? Important data limitations remain to answer this question, especially regarding slaughterhouses, fundamental to the beef supply chain. This paper addresses the data gap on slaughterhouse location and history and provides novel regional analysis. We map the beef industry's evolution into Brazil's interior over the last six decades and quantify changes in market concentration between 2006 and 2016. To accomplish this, we triangulated across fiscal and animal sanitation data sources to produce the first longitudinal dataset with information on the opening and closing dates, locations, and production volumes of 2602 slaughterhouses. We show the linear movement of slaughterhouses and cattle herds to the Amazon by tracking their geographical centres of gravity. We also show the clustering pattern of slaughterhouses. Until the 1960s, all the geographical clusters were located south of the capital, Brasília. By the early 2000s, clusters north of Brasília were almost as extensive. Finally, we assessed the degree of market power that the largest beefprocessing companies possess. The results indicate that market concentration increased in regions of more recent settlement further away from the coast, and that it remained relatively stable in states near the coast (Minas Gerais, São Paulo). The results shed light on the relationship between displacement toward the Amazon and Cerrado regions and economic concentration. [ABSTRACT FROM AUTHOR]

The question of how to generate development while preserving the environment is central to the history of the Brazilian Amazon. Many decades of top-down state interventions conceived and executed under a developmentalist framework have resulted in a socioenvironmental crisis. In response, the Sustainable Oil Palm Production Program (SPOPP) was launched in 2010. It promised to break with developmentalist visions and articulate environmental and sustainability concerns. This paper uses assemblage thinking to examine how these contrasting, often impossible-to-balance, views manifest within SPOPP implementation. We describe how non-human actors (trees, diseases, previous policies and agroecological zoning technologies) interact with human actors. However, powerful actors, in the state and beyond, continue to garner support for their developmentalist interests and thwart or depoliticize environmental and social concerns, thus limiting change.

In this paper, we draw on common-pool resource theory to argue that indigenous territories, when granted full property rights, will be effective at curbing deforestation. Using satellite data, we test the effect of property rights on deforestation between 1982 and 2016. In order to identify causal effects, we combine a regression discontinuity design with the orthogonal timing of homologation. We find that observations inside territories with full property rights show a significant decrease in deforestation, while the effect does not exist in territories without full property rights. While these are local average treatment effects, our results suggest that not only do indigenous territories serve a human-rights role, but they are a cost-effective way for governments to preserve their forested areas. First, obtaining full property rights is crucial to recognize indigenous peoples’ original right to land and protect their territories from illegal deforestation. Second, when implemented, indigenous property rights reduce deforestation inside indigenous territories in the Amazon rain-forest, and could provide an important positive externality for Brazil and the rest of the world in terms of climate change mitigation.

Purpose: The purpose of this paper is to examine the factors that influence the facilities management (FM) in construction sites in the Brazilian Amazon. Design/methodology/approach: The study used structured questionnaires, with the participation of 136 facilities professionals in construction sites in the Brazilian Amazon. These sites were selected with help of 17 facilities managers. The survey achieved a total response rate of 76.5 per cent. The factorial analysis was performed after checking the adequacy of the sample to the technique. The results allowed the continuation of data processing and the use of exploratory factorial analysis to summarize the variables and identify the influencing factors. Findings: The results indicated five factors that influence the FM on construction sites in the Brazilian Amazon, namely: negotiation with local entities; weather; local suppliers; manpower; and logistical infrastructure. With the proper understanding of these factors, facilities professionals could plan actions to minimize negative impacts over the FM on construction sites. Research limitations/implications: The influence of factors on FM was studied from the professionals' viewpoint. It is possible that there are other perspectives or other influencing factors. However, this work is limited to the analysis of the variables that make up the five dimensions presented. Practical implications: Organizations and FM professionals might be interested in the results of this research to enhance the FM performance on the construction sites existed and to plan the implementation of the FM on upcoming construction sites. Originality/value: This paper is the first large research about FM in construction sites conducted in the Brazilian Amazon and serve as a basis to other research works that promote the development of FM in Brazil.

The order Odonata (Insecta) is composed of aquatic insects popularly known as dragonflies and damselflies. Members of this order are closely linked to the conservation status of their habitats; however, the Wallacean shortfall in some regions still remains high. The Volta Grande do Xingu region is known to have high endemism of some groups, such as Actinopterygii (fish), which can be applied to other groups that do not yet have their fauna known at the site, such as the order Odonata. The Wallacean shortfall and constant anthropic changes (for example, the construction of the Belo Monte Hydroelectric) have been obstacles in the preservation of these and other groups. In that regard, the main aim of this paper is to provide a checklist of Odonata (Insecta) adult species from the streams of Volta Grande do Xingu, Pará, Brazil. The collections were carried out in 19 streams in the Volta Grande do Xingu region in September 2019, corresponding to the drought period. A total of 526 specimens were collected, where two suborders, six families, 26 genera and 43 species were identified. Three species of Odonata were registered for the first time in the state of Pará: Erythrodiplax famula (Erichson in Schomburgk, 1848); Acanthagrion chacoense Calvert, 1909 and Epipleoneura lamina Williamson, 1915. These data allow us to help increase the knowledge of Odonata fauna in the streams of Volta Grande do Xingu, a region that is under intense anthropic pressure. This helps to reduce the Wallacean shortfall, with another area sampled for the state of Pará. [ABSTRACT FROM AUTHOR]

Reconciling conservation with rural development often constitutes a socio-environmental dilemma, in which ecotourism plays the part of either the panacea or the ‘poverty trap’ for local populations. Features of the local context, such as social heterogeneity, opportunities for education and jobs, and images of rural and urban life, provide a more nuanced understanding of this polarised debate. In this analysis of a youth ecotourism project, we consider that youth face distinct daily struggles and have aspirations in life that differ from those of the older generation. Therefore, the opportunities/constraints in and around protected areas influence and affect them in particular ways. In this paper, we address the gap in the literature on the position of young people living in peri-urban areas nearby conservation units, as we believe that these factors may shed some lights on the importance of intangible outcomes of sustainable development/conservation projects. Based on data from the peri-urban ‘forest town’ Curuçá on the Amazonian Atlantic coast of Brazil, we discuss how young people, involved in an ecotourism project in the Marine Extractive Reserve Mãe Grande de Curuçá, perceive their roles when it comes to conservation and development, education, jobs and their aspirations for the future.

The definition of priority areas for conservation and integrated management actions are essential for the effective maintenance and recovery of natural populations, especially for species overexploited by humans. Amazonian chelonians are a food resource historically used by people, resulting in the decline of species populations and worsening the risk of local extinctions. In this paper, we establish priority areas and define integrated conservation actions for populations of three Amazonian chelonians most threatened by human consumption in Brazil (Podocnemis expansa, P. unifilis and P. sextuberculata). To do so, we used 15 prioritization criteria (ecological, logistical and socioeconomic) estimated with 30 years monitoring data in 15 areas by the Amazon Chelonian Program (in portugues Projeto Quelonios da Amazonia, PQA). Each criterion presented four levels of priority with scores increasing according to the relevance for conservation of chelonian populations. The sum of the scores obtained in each area of the PQA allowed a ranking and four categories of importance for conservation to be defined. We also analyzed the similarity of scores among areas of the PQA and among the prioritization criteria to evaluate the application of integrated conservation action strategies. The areas of PQA were classified as Extremely Important for Conservation (Rebio Trombetas River, Middle Xingu River, Middle Araguaia River, Upper Guaporé River), Very Highly Important for Conservation (Middle Purus River, Middle Juruá River, Crixás-Açu River Mouth, Sub-middle Tapajós River); Highly Important for Conservation (Sub-Middle Araguaia River, Amazonas River Mouth, Middle Mortes River); and Important for Conservation (Middle Guaporé River, Lower Branco River, Flechal River, Afuá River). The prioritization and similarity analyses can support the development of a national integrated plan of conservation actions to reduce the overexploitation of Amazon chelonian populations, according to the ecological, logistical and socioeconomic needs of each PQA area.

The Brazilian Amazon is marked by attempts at infrastructure-driven development. The construction of the Belo Monte dam, the third-largest in the world, brought chaotical and rapid urbanization to surrounding cities. This paper answered whether the Belo Monte dam impacted the level of violent crime in the region after Altamira was ranked as the most violent city in Brazil in 2015. Following a difference-in-difference approach, I explore the timing of the Belo Monte dam construction and the distance from the construction site to identify the causal effect of unplanned urbanization on homicide rate. In two exogenous shocks, the beginning (2011) and the end of the construction (2015), I estimated a significant rise in the homicide rate in closer cities. The results are driven by criminal activity, with drug trafficking being one of the channels behind the rising homicide rate during construction. The homicide victims are mainly the young male population causing a significant loss of human capital. The increasing homicide rate after the end of the construction indicates that the Belo Monte dam may have a long-term effect on the violence level in the region. Violence imposes high social costs and may jeopardize future growth in the Amazon. [ABSTRACT FROM AUTHOR]

Background: This paper explores patterns of women's medicinal plant knowledge and use in an urban area of the Brazilian Amazon. Specifically, this paper examines the relationship between a woman's age and her use and knowledge of medicinal plants. It also examines whether length of residence in three different areas of the Amazon is correlated with a woman's use and knowledge of medicinal plants. Two of the areas where respondents may have resided, the jungle/seringal and farms/colonias, are classified as rural. The third area (which all of the respondents resided in) was urban. Methods: This paper utilizes survey data collected in Rio Branco, Brazil. Researchers administered the survey to 153 households in the community of Bairro da Luz (a pseudonym). The survey collected data on phytotherapeutic knowledge, general phytotherapeutic practice, recent phytotherapeutic practice and demographic information on age and length of residence in the seringal, on a colonia, and in a city. Bivariate correlation coefficients were calculated to assess the inter-relationships among the key variables. Three dependent variables, two measuring general phytotherapeutic practice and one measuring phytotherapeutic knowledge were regressed on the demographic factors. Results: The results demonstrate a relationship between a woman's age and medicinal plant use, but not between age and plant knowledge. Additionally, length of residence in an urban area and on a colonia/farm are not related to medicinal plant knowledge or use. However, length of residence in the seringal/jungle is positively correlated with both medicinal plant knowledge and use. Conclusions: The results reveal a vibrant tradition of medicinal plant use in Bairro da Luz. They also indicate that when it comes to place of residence and phytotherapy the meaningful distinction is not rural versus urban, it is seringal versus other locations. Finally, the results suggest that phytotherapeutic knowledge and use should be measured separately since one may not be an accurate proxy for the other. [ABSTRACT FROM AUTHOR]

Population growth and rising incomes have led to increasing global demand for meat products. Meeting this demand without converting remaining natural ecosystems or further degrading ecosystems is one of the largest global sustainability challenges. A critical step to overcoming this challenge is to increase the productivity of livestock grazing systems, which occupy the largest land area of any type of agriculture globally. Integrated crop−livestock systems (iCL), which re-couple crop and livestock production at the farm scale, have been considered a promising strategy to tackle this challenge by restoring degraded pasturelands and providing supplemental nutrition to livestock. However, few studies have analyzed the economic viability of such systems, especially in Brazil, an important player in global food systems. This paper presents an economic analysis of iCL in Mato Grosso, Brazil, the largest grain and beef producer in the country, which spans the ecologically diverse Amazon, Cerrado and Pantanal biomes. We compare the economic performance of an integrated soybean/corn and beef cattle system to a continuous crop (soybean/corn) system and a continuous livestock (beef cattle) production system from 2005 to 2012. We use empirical case study data to characterize a 'typical' farm for each production system within the study region. We find that the integrated crop−livestock system has a higher annual net present value (NPV) per hectare (ha) than continuous cropping or livestock under a range of discount rates. However, under a scenario of substantially higher crop prices, the continuous cropping outperforms iCL. While iCL is not feasible in all regions of the Amazon and Cerrado, our results indicate that in places where the biophysical and market conditions are suitable for production, it could be a highly profitable way to intensify cattle production and potentially spare land for other uses, including conservation. Nevertheless, additional credit and technical support may be needed to overcome high upfront costs and informational barriers to increase iCL areas as a sustainable development strategy for agriculture in the Amazon and Cerrado regions.

Developing institutional arrangements for supporting sustainable fisheries has been a critical challenge for the governance of common-pool resources, especially in transboundary regions. In this paper, we analyze the impact of governance arrangements on a small-scale fishery system on the Brazil-Bolivia border in the Amazon region. Data collection involved documental analysis, literature review and conduction of semi-structured interviews with fishers and environmental protection/regulatory agencies' staff. We present an exploratory qualitative analysis of the interactions between the fishery system's attributes (biological, environmental, technical and governance), examining institutional arrangements among diverse stakeholders. Results reveal that the small-scale fishery characteristics and the relationships between resources and stakeholders has contributed to stock maintenance and overall sustainability of the fishery system. Nevertheless, we also found that the governance structure is fragile due to weak institutional arrangements within and between countries, resulting in increased vulnerability of the fishery system to imminent threats.

Aerosols and primary biological aerosol particles (PBAPs) play an important role in regulating the global climate, but information summarizing the available knowledge is limited. Here, we present a systematic review of in situ studies performed in the last 35 years on aerosols–PBAPs in Brazil, with 212 studies encompassing 474 cases. The Amazon rainforest was the most studied biome, represented by 72% of cases, followed by the Atlantic Forest with 18%. Studies focusing the Amazon mostly investigated climate-related issues and aerosol physics, with less than 5% examining the biological identity of aerosols, whereas outside the Amazon, this number reached 16%. Whilst more than half of the cases within Amazon (55%) were held at seven sampling sites only, conclusions were mainly extrapolated to the entire biome. Contrarily, research beyond the Amazon has mostly addressed the temporal and biological characterisation of PBAPs, and not only is it scattered, but also scarce. Regarding sampling efforts, most cases (72%) had fewer than 100 days of sampling, and 60% of them spanned less than half a year of study. We argue that scientists should produce more detailed/complete assessments of aerosols–PBAPs in Brazil as a whole, particularly considering their biological identity, given their importance to global climate regulation.

This article reviews the main themes-we are here; this is who we are; insurgent citizenship; Amazon Nation-elaborated in this collection of papers on new Amazonian geographies, and extends their implications to ideas about governmentality and regional identity. The article contextualizes the papers in this issue through understanding Amazonia's role in the structuring of the contemporary Brazilian state through resistance to conventional modernist authoritarian development planning, and the creation of current places and politics through the assertion of new forms of citizenship, identity, governance and the rise of socio-environmentalisms as part of a new 'statecraft' from below. Modern Amazonia has reasserted itself by developing a set of alternative epistemes and practices which can be seen, in their language and ideologies, to invoke the idea of the 'Amazon nation.' This article emphasizes the cultural underpinnings of these processes in a contested Amazon that is now a major supplier of global agricultural commodities in its deforested landscapes, and pivotal for local livelihoods and planetary environmental services in its forested ones.

Societal Impact Statement: Society is increasingly concerned over the environmental impact of diets. Much of this concern is over the environmentally destructive nature of meat production, especially beef and especially in the Amazon. This article aims to understand the production of beef in Brazil through the understudied perspective of forage grasses. In doing so, the article traces who was involved in the importation and improvement of forage grasses in Brazil, why they were involved, and what the consequences of their actions were. By centering forage grasses, we can better understand the potential consequences of seemingly unimportant plant breeding efforts. Summary: Beef is viewed by many as one of the more environmentally destructive foods today. Whether it is deforestation in the Amazon or concentrated feedlots, the rancher and the cow have come to epitomize the dangers of a global industrial food system. This article looks at the industrialization of beef cattle from another angle, a bit closer to the ground. It looks at the role and circulation of plants and plant breeders in the expansion of beef cattle in the Brazilian tropics.The article draws on documents collected from the institutional archives of the Brazilian Agricultural Research Corporation, known by its Portuguese acronym Embrapa and the Rockefeller Archive Center. Additional archival documents were acquired by a personal contact. Embrapa was established in 1973, but its archives contain documents from Brazilian agricultural research agencies from as far back as 1952. Documents from the Rockefeller Archive Center include research bulletins and reports from Nelson Rockefeller's IBEC Research Institute (IRI), which conducted research on forage grasses from the 1950s until the 1970s.The article puts forth the argument that imported and improved forage grasses made large‐scale cattle ranching environmentally viable and economically profitable in Brazil. One type of grass in particular, Brachiaria, was central in propelling Brazil as the world's largest producer of beef and underpinning perhaps the most environmentally and socially destructive cattle ranching system in the world. Brachiaria was a key biological and technological input to further entrench longstanding structural inequalities of land ownership.One of the key conclusions of this article is that perspectives from the margins can be illustrative of how seemingly unimportant research (forage grass breeding) can have massive consequences as part of a broader socio‐environmental system.

There is a 50% possibility that global temperatures will have risen by more than 5 °C by the year 2100. As demands on Earth's systems grow more unsustainable, human security is clearly at stake. This narrative review provides an overview and synthesis of findings in relation to climate change, air pollution, and human health within the Global South context, focusing on case study geographic locations in South Africa and Brazil. Two case study regions—the Kruger to Canyons Biosphere region of South Africa and the Amazon region of Brazil—were the subjects of PubMed literature searches. Technical reports, policy briefs, and grey literature were also narratively synthesized. The burning of wood for fuel, as witnessed in Agincourt, and forest fires, such as those seen in the Amazon rainforest, release air pollutants such as methane and black carbon, which are strong short-lived climate pollutants (SLCPs) which fuel climate change and adversely affect human health. SLCPs have a brief lifetime in the atmosphere, but they frequently have a far larger potential for global warming than carbon dioxide (CO2). Most air pollution in geographic case study areas, that are home to human settlements, is due to the burning of wood and other biomasses that are pollutants. These areas are seen to be important for climate and health responses, and if constructive action is taken to switch to other modes of electricity generation (such as solar power) and the prevention of deforestation, the worst of the impacts may still be mitigated in these regions. Authorities should also establish a monitoring strategy for air quality, as well as enforce air quality regulations that safeguard public health. [ABSTRACT FROM AUTHOR]

Peropteryx pallidoptera is the newest described species of Peropteryx, know from only few localities in Ecuador, Peru, Brazil, Colombia, and Bolivia. Herein, we report new records of this species, and we show that P. pallidoptera has a wider distribution than known across the Amazon. Our records are based on field sampling and, mostly, on museum vouchers, which reinforces the importance of biological collections and the need to continually review deposited specimens.

This paper discusses how to make multidisciplinary research more effective at influencing policies related to deforestation. It reviews previous experiences with multidisciplinary farming systems research and the difficulties bringing together researchers from different disciplines. Leadership, value added, timeliness, targeted communications, and work at multiple scales are identified as important characteristics of policy-effective research. Three examples of effective multidisciplinary research are presented: IPAM's research on deforestation for soybeans and beef in the Brazilian Amazon, CIFOR's research on pulp and paper in Indonesia, and IPAM's research on logging concessions in Brazil.

This paper considers the size of a farmer’s property as a key variable influencing land cover and land cover change in rural areas of developing countries. Data from 126 rural familial properties in the region around the city of Santarém, Pará, in the Brazilian Amazon, indicate that property size is important for understanding the trajectories of land cover change. Past research has focused on the distinction between small family farms and large capitalized farms, arguing that family farmers have a higher deforestation intensity, or on estimating the strength of the effect of property size relative to economic or demographic factors. This paper shows that larger familial properties are able both to retain a larger area in forest and to have long enough cycles of use and fallow to allow previously used land to become forested again. Based on these analyses and discussion, we argue that land use and land cover research must consider property size as an organizing principle in order to better comprehend the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon and other rural landscapes.

This paper argues against what we call 'the local trap', in which development researchers and practitioners falsely assume that localized decision-making is inherently more socially just or ecologically sustainable. The local trap constrains research on a range of topics in development research, including productive conservation networks, agro-forestry, community-based natural resource management, common property regimes and community-based collaboration. We use recent research on scale in political and economic geography to argue that scales and scalar arrangements are socially constructed through political struggle; they are never ontologically given. In other words, there is nothing inherent about any scale or scalar arrangement. Therefore, an arrangement in which resources or decisions are controlled locally is no more likely to lead to ecologically sustainable or socially just outcomes than an arrangement in which the regional, national or global scale predominates. Because scales are produced through socio-political struggle, the outcomes of a given scalar arrangement are dependent on the political agenda(s) of those empowered by the arrangement. When we start from the assumption that there is nothing inherent about scale, we cannot assume the political and ecological dynamics of a particular scalar configuration. We must instead make those dynamics the object of critical inquiry. The paper uses a case study of beekeeping in the Brazilian Amazon to illustrate the range of both positive and negative outcomes that can result when decision-making is localized.

The Brazilian Amazon forest and cerrado savanna encompasses a region of enormous ecological, climatic, and land-use variation. Satellite remote sensing is the only tractable means to measure the biophysical attributes of vegetation throughout this region, but coarse-resolution sensors cannot resolve the details of forest structure and land-cover change deemed critical to many land-use, ecological, and conservation-oriented studies. The Carnegie Landsat Analysis System (CLAS) was developed for studies of forest and savanna structural attributes using widely available Landsat Enhanced Thematic Mapper Plus (ETM+) satellite data and advanced methods in automated spectral mixture analysis. The methodology of the CLAS approach is presented along with a study of its sensitivity to atmospheric correction errors. CLAS is then applied to a mosaic of Landsat images spanning the years 1999–2001 as a proof of concept and capability for large-scale, very high resolution mapping of the Amazon and bordering cerrado savanna. A total of 197 images were analyzed for fractional photosynthetic vegetation (PV), nonphotosynthetic vegetation (NPV), and bare substrate covers using a probabilistic spectral mixture model. Results from areas without significant land use, clouds, cloud shadows, and water bodies were compiled by the Brazilian state and vegetation class to understand the baseline structural typology of forests and savannas using this new system. Conversion of the satellite-derived PV data to woody canopy gap fraction was made to highlight major differences by vegetation and ecosystem classes. The results indicate important differences in fractional photosynthetic cover and canopy gap fraction that can now be accounted for in future studies of land-cover change, ecological variability, and biogeochemical processes across the Amazon and bordering cerrado regions of Brazil.

Habitat fragmentation remains a major focus of research by ecologists decades after being put forward as a threat to the integrity of ecosystems. While studies have documented myriad biotic changes in fragmented landscapes, including the local extinction of species from fragments, the demographic mechanisms underlying these extinctions are rarely known. However, many of them—especially in lowland tropical forests—are thought to be driven by one of two mechanisms: (1) reduced recruitment in fragments resulting from changes in the diversity or abundance of pollinators and seed dispersers or (2) increased rates of individual mortality in fragments due to dramatically altered abiotic conditions, especially near fragment edges. Unfortunately, there have been few tests of these potential mechanisms due to the paucity of long‐term and comprehensive demographic data collected in both forest fragments and continuous forest sites. Here we report 11 years (1998–2009) of demographic data from populations of the Amazonian understory herb Heliconia acuminata (LC Rich.) found at Brazil's Biological Dynamics of Forest Fragments Project (BDFFP). The data set comprises >66,000 plant × year records of 8586 plants, including 3464 seedlings established after the first census. Seven populations were in experimentally isolated fragments (one in each of four 1‐ha fragments and one in each of three 10‐ha fragments), with the remaining six populations in continuous forest. Each population was in a 50 × 100 m permanent plot, with the distance between plots ranging from 500 m to 60 km. The plants in each plot were censused annually, at which time we recorded, identified, marked, and measured new seedlings, identified any previously marked plants that died, and recorded the size of surviving individuals. Each plot was also surveyed four to five times during the flowering season to identify reproductive plants and record the number of inflorescences each produced. These data have been used to investigate topics ranging from the way fragmentation‐related reductions in germination influence population dynamics to statistical methods for analyzing reproductive rates. This breadth of prior use reflects the value of these data to future researchers. In addition to analyses of plant responses to habitat fragmentation, these data can be used to address fundamental questions in plant demography and the evolutionary ecology of tropical plants and to develop and test demographic models and tools. Though we welcome opportunities to collaborate with interested users, there are no restrictions on the use of this data set. However, we do request that those using the data for teaching or research purposes inform us of how they are doing so and cite this paper and the data archive when appropriate. Any publication using the data must also include a BDFFP Technical Series Number in the Acknowledgments. Authors can request this series number upon the acceptance of their article by contacting the BDFFP's Scientific Coordinator or E. M. Bruna. [ABSTRACT FROM AUTHOR]

Belo Monte is one of the most divisive dams in Brazilian history, becoming entangled in a thirty-year struggle between pro- and anti-dam interests over the role of the facility within a complex web of Brazilian development and the future of the Brazilian Amazon. This research explores how the proponents of Belo Monte have adopted a number of policy frames as a means of deflection, to divide the opposition and legitimize the project. It investigates this claim by analyzing speeches given within the Brazilian Câmara dos Deputados and the public speeches of high-level politicians. These sources, organized around a framework previously identified by Ahlers et al. (), show that the government and individual politicians have used a variety of framing devices to legitimize the hydroelectric facility. Principal methods of framing used also demonstrate how contemporary narratives (e.g. sustainability) have been employed to deflect opposition criticism and widen the scheme's perceived beneficiaries. In doing so, this paper demonstrates how the transformation represented by Belo Monte encompassed not only a process of engineering but also a re-articulation of the complex and its role in modern Brazil.

Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from large baleen whales to sperm and beaked whales, as well as pelagic dolphins. This paper describes new cetacean records from north and north-eastern Brazil, which are both the least surveyed areas regarding aquatic mammals. Regular beach surveys were conducted to recover cetacean carcasses along the coast of Pará beginning November 2005. At the coasts of the Maranhão and Piauí states, the surveys were conducted between 2003 and 2013. From 2003 to 2014, 34 strandings of cetaceans were registered. The study provides four additional species records' in the area based on strandings (Balaenoptera borealis, Balaenoptera physalus, Peponocephala electra, and Pseudorca crassidens). A mass stranding of Guiana dolphins (Sotalia guianensis, N = 12), the most common species for the region, was reported for the first time. The records presented herein are of special concern, since they expand the knowledge on cetaceans from the Brazilian coast. In addition, this study conducted an analysis to verify the similarity between cetacean compositions described for north and north-eastern Brazil and the southern Caribbean region. The results showed a high similarity between these regions, proving the connection with the Caribbean cetacean fauna. [ABSTRACT FROM AUTHOR]

This paper examines how scientists deal with tensions emerging from their role as providers of objective knowledge and as citizens concerned with how their research influences policy and politics in Brazil. This is accomplished through an ethnographic account of scientists using remote sensing technology, of their knowledge-making activities and of the broader socio-political controversies that permeate the detection of deforestation in the Amazon rainforest. Strategies for mitigating uncertainty are central aspects of the knowledge practices analyzed, bringing controversies ‘external’ to the laboratory ‘into’ the lab, making these boundaries conceptually problematic. In particular, the anticipation of alternative interpretations of rainforest cover is a crucial way that scientists bring the world into the lab, helping to shed light on how scientists, usually seen and analyzed as isolated, are in fact often in constant dialogue with the broader political controversies related to their work. These insights help question the idea that the monitoring of deforestation through remote sensing is a form of secluded research, drawing a more complex picture of the dual role of scientists as knowledge producers and concerned citizens.

Background: Rhipicephalus (Boophilus) microplus is the most important tick species affecting cattle in the world. Under field conditions, the non-parasitic phase of R. (B.) microplus is unknown in the Amazon biome, including Brazil. The present study aimed to evaluate the non-parasitic phase of R. (B.) microplus in field (grass plots) and laboratory conditions. Methods: The study was conducted from September 2020 to April 2022 in an Amazonian region (Maranhão State, Brazil). We evaluated the biological parameters of R. (B.) microplus under laboratory and field conditions. Engorged females were exposed to experimental conditions every 14 days, totaling 20 months of study. The following biological parameters were observed: pre-oviposition period, egg mass incubation period, and maximum larval survival period. Results: Abiotic data (e.g., temperature and humidity) varied little throughout the year. Precipitation was the factor that varied the most throughout the year (dry ~ 30 mm3 and rain 400 mm3), and the parameters of pre-oviposition and pre-hatching are longer during the rainy season. A possible negative effect of the dry season on the percentage of hatched eggs was observed. Larval longevity in the plots of both control and free females was short (mean ~ 50–60 days), below that recorded for larvae under controlled conditions (mean ~ 95 days). Conclusions: Rhipicephalus (Boophilus) microplus was able to complete its non-parasitic phase by producing host-seeking larvae in the pasture during all months of the study. The results indicate that R. (B.) microplus can complete up to six generations per year in biome Amazon. To our knowledge, this is the highest number of annual generations for R. (B.) microplus in Latin America. [ABSTRACT FROM AUTHOR]

Neurocysticercosis, a parasitic infection of the central nervous system (CNS), is a significant public health issue globally, including in Brazil. This article presents a case report of a 44-year-old male patient residing in the rural area of Roraima, the northernmost region of Brazil within the Amazon Forest. The patient, with chronic HIV infection, acquired the Taenia solium helminth, resulting in neurocysticercosis development. Remarkably, the diagnosis of neurocysticercosis was not initially apparent but emerged through meticulous analysis following a motorcycle accident. The absence of seizures, a common clinical manifestation, complicated the diagnostic process, making it an uncommon case of NCC, which may be related to co-infection. As the patient's condition progressed, multiple complications arose, requiring additional medical attention and interventions. This case underscores the immense challenges faced by healthcare teams in managing neurocysticercosis effectively. It emphasizes the critical need for a comprehensive, multidisciplinary approach to provide optimal care for such complex cases. The study's findings underscore the importance of raising awareness and implementing improved strategies for tackling neurocysticercosis, particularly in regions where it remains a prevalent concern.

Bats are widely distributed in Brazil, including the Amazon region, and their association with viral pathogens is well-known. This work aimed to evaluate the metavirome in samples of Molossus sp. bats captured in the Brazilian Amazon from 2019 to 2021. Lung samples from 58 bats were divided into 13 pools for RNA isolation and sequencing followed by bioinformatic analysis. The Retroviridae family showed the highest abundance of viral reads. Although no complete genome could be recovered, the Paramyxoviridae and Dicistroviridae families showed the formation of contigs with satisfactory identity and size characteristics for further analysis. One contig of the Paramyxoviridae family was characterized as belonging to the genus Morbillivirus, being grouped most closely phylogenetically to Porcine morbillivirus. The contig related to the Dicistroviridae family was identified within the Cripavirus genus, with 94%, 91%, and 42% amino acid identity with Culex dicistrovirus 2, Rhopalosiphum padi, and Aphid lethal paralysis, respectively. The presence of viruses in bats needs constant updating since the study was able to identify viral sequences related to families or genera still poorly described in the literature in association with bats.

The Amazon Basin occupies a vast portion of northern South America and contains some of the highest species richness in the world. The northern Brazilian state of Amapá is delimited by the Amazonas River to the south, the Oyapock River to the northern boundary with French Guyana, and the Atlantic northeastern coast to Amazon estuary. Despite several expeditions to the Amazon in recent decades, little is known about the freshwater ichthyofauna from Amapá, with records limited to local inventories and species descriptions. This paper presents a compilation of the freshwater fish diversity sampled in fifteen sites covering two major Amapá ecoregions during the dry season of 2015. 120 species representing eight orders and 40 families are reported upon in this work. Eight species appear for the first time in the Brazilian territory providing new information for future conservation status evaluations. [ABSTRACT FROM AUTHOR]

Introduction Breastfeeding is an important determinant of child survival and normal growth and development, but breastfeeding prevalence is generally low in Brazil. Factors associated with infant feeding practices there are not well understood. This paper examines factors associated with breastfeeding cessation in a township in the western Brazilian Amazon. Methods A cross-sectional, population-based study was conducted among children younger than 25 months and collected information on maternal and child characteristics. Survival analysis based on a proximal-distal framework examined the association between breastfeeding duration and socioeconomic and maternal/child biological factors. Results The median breastfeeding duration among 101 children who were no longer breastfeeding was 120 days. Almost two-thirds (63 %) of these children stopped breastfeeding before 6 months of age. In the larger sample of 209 children, 74.6 % had previously been bottle-fed. Considering the full proximal-distal model, a child who had ever been bottle-fed was expected to cease breastfeeding about 88 % sooner than one who was never bottle-fed ( p < 0.001). Children in the second-poorest wealth quartile stopped breastfeeding sooner than children in the poorest quartile ( p < 0.05). Discussion Breastfeeding cessation in the study area occurred much earlier than the recommended 2 years of age. Factors associated with ending breastfeeding early included ever-use of a bottle, having a single mother, and belonging to the second-poorest wealth quartile. Further research is needed to better understand these factors and other barriers women face to continuing breastfeeding. [ABSTRACT FROM AUTHOR]

Given the importance of land for indigenous peoples, rural out-migration is usually associated with a disruption of indigenous culture. This paper suggests that instead of being a disruptive process, migration can serve as the means for a ‘scale shift’ that transports mobilization capacity from one location to another. This contribution presents the case of Barcelos, in the Brazilian Amazon, where an indigenous movement first arose in an urban area, due to the migration of indigenous activists from other locations, and later spread to rural communities as a result of local migratory circulation. Through alliances with the regional indigenous movement, these rural communities became part of a broader mobilization network that supported the indigenous resurgence in Barcelos.

is a haematophagous mite of veterinary and public health concern. The association between O. bursa and humans in Brazil has been known for several decades, but most of the information is limited and confusing. Herein, we present an overview of the cases of gamasoidosis in Brazil based on published and new records. Wild birds are common sources for human infestation, especially omnivorous and insectivorous birds that live in urban and rural environments. Species of the Columbidae are the most common birds associated with O. bursa in Brazil. [ABSTRACT FROM AUTHOR]

This paper discusses how changing urban-rural relationships pose new opportunities and challenges for resource management in the municipality of Barcelos, Middle Rio Negro, Brazilian Amazon. The conflicts arising from poor delimitation of the rights of different resource users, as well as increasing rural-urban connections, have mobilised indigenous peoples to seek to protect traditional fishing territories. However, people's mobility challenges resource management models that are based on permanent residence. This complexity underscores the urgent need for new ecological and political management models to deal with the flux of both people and natural resources, without excluding minority groups.

In the Brazilian social context, characterized by the enormous ethnic-racial, cultural, religious, and identity diversity, where occurs certain invisibility of the Jews in the national culture and especially in the Amazonian society, it is relevant to research the presence of Jews in Brazil. As in other parts of the country, Amazon was also marked by the arrival of this ethnic-religious community. To understand their historical trajectory, identity, symbolic representations, religious traditions, and practices requires a multidisciplinary approach involving the history, sociology, anthropology, theology, and religious studies. From a literature review, the objective of this paper is to understand the coexistence, the articulation with the local religiosity, and the strengthening of the cultural elements that permeate the Jewish identity and the meaning that the Amazonian populations attribute to the culture, symbols and religious rites of the Yehudei Amazonya.

Summary: Gazetting and maintaining protected areas (PAs) are political processes and, as such, depend on wider society's support in order to achieve their aims. In this paper, we evaluated the influence of gender, education, age, income, place of origin and place of residence on public support for PAs in the Brazilian state of Amapá, a new tropical forest frontier. We gathered 615 complete interviews with adults living in both rural and urban settings. We found that most (90.5%) of the participants support PAs and that this attitude is more likely to exist among urban than rural participants. We found that gender, education, age, income and place of origin did not influence support for PAs. Biodiversity conservation is the most common reason why PAs receive public support. In contrast, participants who do not favour PAs see them as providing no benefit to people. We suggest that support by local political leaders from dominant and rival political parties for conservation helps to promote acceptance of PAs by stakeholders. However, relatively low support for PAs among rural participants could indicate that the expectations of these populations regarding the social benefits associated with this conservation policy have yet to be fulfilled.

Human intoxication to mercury is a worldwide health problem. In addition to the type and length of exposure, the genetic background plays an important role in mercury poisoning. However, reviews on the genetic influence in mercury toxicity are scarce and not systematic. Therefore, this review aimed to systematically overview the most recent evidence on the genetic influence (using single nucleotide polymorphisms, SNPs) on human mercury poisoning. Three different databases (PubMed/Medline, Web of Science and Scopus) were searched, and 380 studies were found that were published from 2015 to 2022. After applying inclusion/exclusion criteria, 29 studies were selected and data on characteristics (year, country, profile of participants) and results (mercury biomarkers and quantitation, SNPs, main findings) were extracted and analyzed. The largest number of studies was performed in Brazil, mainly involving traditional populations of the Tapajós River basin. Most studies evaluated the influence of the SNPs related to genes of the glutathione system (GST, GPx, etc.), the ATP-binding cassette transporters and the metallothionein proteins. The recent findings regarding other SNPs, such as those of apolipoprotein E and brain-derived neurotrophic factor genes, are also highlighted. The importance of the exposure level is discussed considering the possible biphasic behavior of the genetic modulation phenomena that could explain some SNP associations. Overall, recommendations are provided for future studies based on the analysis obtained in this scoping review. [ABSTRACT FROM AUTHOR]

Simple Summary: A new genus of hilarine dance fly, i.e., Tropicohilara, is described with six new included species. The new genus is recorded from the Amazon and Atlantic Forest biomes. The morphology and distribution of the genus are discussed. The genus Tropicohilara gen. nov. (Diptera: Empididae: Empidinae: Hilarini) is described and includes the following six new species from Brazil: Tropicohilara amazonensis sp. nov. (type species, Brazil: Amazonas, Manaus); T. bahiensis sp. nov. (Brazil: Bahia, Camacan); T. bella sp. nov. (Brazil: Pernambuco, Jaqueira); T. mineira sp. nov. (Brazil: Minas Gerais, Itamonte); T. paranaensis sp. nov. (Brazil: Paraná, Piraquara); and T. sinclairi sp. nov. (Brazil: Paraná, Morretes). The genus is presently recorded from the Amazonian and Atlantic Forest biomes. It differs from other hilarine genera by the following combination of characteristics: predominantly yellowish specimens; occiput somewhat conical in dorsal view; postpedicel elongate, male first fore tarsomere unmodified; hind tibia slightly shorter than hind femur; wing vein R2+3 with setae on ventral surface; male tergite 7 with a sclerotized band at posterior margin, tergite 8 reduced and upwardly directed so that terminalia can be flexed forward. A key to the species is provided. [ABSTRACT FROM AUTHOR]

In Brazil, three out four bat species from the genus Nyctinomops are known. Most of occurrences of these species are based on captures with mist-nets. In this study, we extend the distribution of Nyctinomops aurispinosus in Brazil, providing new records for the Brazilian states of Mato Grosso (1), Roraima (1), Pará (2) and Pernambuco (1). We also confirm the use of new types of shelter by N. aurispinosus, such as rock crevices in dryland environments and river boulders. We provide new fundamental information about the biology, behavioural and ecological patterns of this species. [ABSTRACT FROM AUTHOR]

Biomass burning (BB) emissions negatively impact the biosphere and human lives. Orbital remote sensing and modelling are used to estimate BB emissions on regional to global scales, but these estimates are subject to errors related to the parameters, data, and methods available. For example, emission factors (mass emitted by species during BB per mass of dry matter burned) are based on land use and land cover (LULC) classifications that vary considerably across products. In this work, we evaluate how BB emissions vary in the PREP-CHEM-SRC emission estimator tool (version 1.8.3) when it is run with original LULC data from MDC12Q1 (collection 5.1) and newer LULC data from MapBiomas (collection 6.0). We compare the results using both datasets in the Brazilian Amazon and Cerrado biomes during the 2002–2020 time series. A major reallocation of emissions occurs within Brazil when using the MapBiomas product, with emissions decreasing by 788 Gg (−1.91% year−1) in the Amazon and emissions increasing by 371 Gg (2.44% year−1) in the Cerrado. The differences identified are mostly associated with the better capture of the deforestation process in the Amazon and forest formations in Northern Cerrado with the MapBiomas product, as emissions in forest-related LULCs decreased by 5260 Gg in the Amazon biome and increased by 1676 Gg in the Cerrado biome. This is an important improvement to PREP-CHEM-SRC, which could be considered the tool to build South America's official BB emission inventory and to provide a basis for setting emission reduction targets and assessing the effectiveness of mitigation strategies.
