The distribution and concentration of iron in seawater and plankton were studied under different ammonium concentrations along a 22 day mesocosm experiment in order to assess possible effects of aquaculture over the phytoplankton and the biogeochemistry in fjords of Chile. Brackish and marine water were used in two different setups, each one with 1 control and 4 different NH
4 + concentrations. Total Chelex labile (TFeCh ), dissolved Chelex labile (DFeCh ) and DGT labile (FeDGT ) iron measurements were performed in seawater, wheile the particulate iron content was determined as total (PFe) and fractionated (PFeSF ) for the plankton community. Average concentration per treatment showed higher concentrations for both TFeCh and DFeCh in the marine system compared to the brackish. TFeCh showed general increasing trend in time and with increasing ammonium concentration, exhibiting positive correlation to the chlorophyll and particulate organic carbon content, whereas DFeCh presented an inverse pattern as expected. FeDGT showed an average lower concentration compare to DFeCh with final concentrations significantly lower in treatments with artificial ammonium addition. PFe showed an increasing trend in time and with increasing ammonium in both systems. Yet, when normalized to Chlorophyll a or particulate organic carbon the trend inverted, showing that at higher ammonium loading the iron per Chlorophyll a or particulate organic carbon decreases. PFeSF major changes occurred in the marine system in the ratio between the 20-140 μm and the 2-20 μm fractions, suggesting possible community structure shift. Overall, ammonium input indicated an effect over iron in the seawater and the particulate matter, depending on the iron form and the microbial assemblage. The further changes over the microbial composition due to ammonium addition may affect the cycling of iron, having possible negative or positive feedbacks over major biogeochemical cycles.

This paper explores the relationships between humans and more-than-humans through the analysis of the rhythmic elements of the contemporary art installation Ajuar para un conquistador. An interdisciplinary approach bridges Art Studies and More-Than-Human Geographies to examine Ajuar and its environmental concerns, including the relationships between human and non-human worlds. Through 'rhuthmanalysis' – a new concept and word developed in the paper – textual and image analysis, and conversations with the artist, this study examines the social, cultural, and ecological meshwork of rhythms articulated within and by the art installation. 'Rhuthmanalysis' expands upon Henri Lefebvre and Catherine Régulier's rhythmanalytic project by incorporating Indigenous knowledge and an ecocritical standpoint while redefining the understanding of rhythm. The analysis explores how Ajuar, concerned with the endangerment of Patagonian birds, promotes a performative understanding of the artwork's capacities in the context of the interplay between the affective dimensions and politics of the creation of the Argentine nation-state. The paper argues that Ajuar participates in the social and political production of space and place, opening new forms of being together and challenging colonial narratives through a rhythmic lens. Moreover, this study seeks to offer a singular perspective on how approaching art as a rhythmic configuration of an intricate choreography of coexistence can provide unique insights into space and the environment. The paper concludes that 'rhuthmanalysis' is a privileged tool to address the need for a transdisciplinary methodology capable of giving account of the mutual unfolding of human and non-human existences and decolonising posthumanist geographies and rhythm studies.

This paper deploys an anthropological concept of "theopolitics" to reflect on the political work done and undone by the action of grace during a dam conflict in the Aysén region of Chilean Patagonia. Exploring procedural affinities between the state's instruments for regulating environmental conflict and theories of assemblage that trace relations to overcome Western ontologies, I suggest that their convergent demand for relations to be rendered visible as the condition of environmental justice violated the ethic of gratuity through which Ayseninos participate in collective life on the Patagonian frontier. Instead of arguing for a better capture of grace within accounts of sociality, I suggest that researchers accompanying anti-extractive struggles should attend to how untraceable but nonetheless highly effective forces like grace convene coalitions for environmental justice and thus to the theopolitical conditions of staging challenges to the state and capital in Latin America. Resumen: Este trabajo antropológico conceptualiza la "teopolítica" para investigar la acción de la gracia en un conflicto de represas en la región patagónica de Aysén, Chile. Yuxtaposicionando los procedimientos del estado chileno para regular los conflictos ambientales con teorías de ensamblaje que rastrean relaciones para representar ontologías alternativas a la occidental, sugiero que su convergencia en condicionar la justicia ambiental en la visibilización de las relaciones viola la ética de gratuidad con la cual participan los ayseninos en la vida colectiva de la frontera patagónica. En lugar de abogar por una mejor captura de la gracia, propongo que los investigadores que acompañan las luchas antiextractivas latinoamericanas presten más atención la participación de fuerzas no rastreables pero no obstante muy eficaces, como la gracia, en convocar movimientos para la justicia ambiental y, así mismo, a las condiciones teopolíticas de los desafíos al estado y al capital en Latinoamerica.

We assessed temporal variability in phytoplankton biomass, Chlorophyll a, nutrient availability, Gross Primary Production (GPP), community respiration (CR), and bacterial secondary production (BSP) over a year of monthly observations (October 2007 to October 2008) at a fixed station in the Puyuhuapi fjord, Chilean Patagonia (44°S, 73°W). A set of in situ observations gathered over two consecutive spring-summer seasons, and one autumn-winter season in the middle, has made it possible to connect the two-phase (i.e. productive season/non-productive season) pattern of Chlorophyll a (Chl a) variability shown by satellite data with a two-phase cycle in GPP, CR, and the composition of phytoplankton assemblages. Estimates of annual GPP and CR, integrated over the top 20 meters of the water column, were 533 and 537 g C m
-2 yr-1 , respectively. Low values of pCO2 were measured in mixed layer autotrophic waters (GPP/CR>1) while high pCO2 levels were measured in mixed layer heterotrophic waters (GPP/CR<1). Bacterial Secondary Production (BSP) was significantly and positively correlated with GPP (r = 0.6, p < 0.05, n = 24) and Chl a (r = 0.4, p < 0.05, n = 24) on an annual cycle basis. The winter drop in bacterioplankton (both bacteria and archea) activity (from 0.9±0.6 g C m-2 d-1 to 0.6±0.3 g C m-2 d-1 ) was not as pronounced as the winter drop in phytoplankton activity (from 1.1±1.12 g C m-2 d-1 to 0.1±0.09 g C m-2 d-1 ). It is hypothesized that dissolved organic matter (DOM) of terrestrial origin plays an important role (especially in winter) supporting bacterial activity in the Puyuhuapi fjord.

ELECTRONIC publications - Abstract
This paper is part of the research project "Anglophony in the Río de la Plata: intercultural spaces and expressions within the society". It works with the concepts of intercultural philosophy, cultural configuration and considers the role of Anglophony and translation in the context of the province of Buenos Aires. Among the texts in its corpus are Cunninghame Graham's: "La pulpería" (1900) and Hudson's Idle Days in Patagonia (1893). These texts according to Graham-Yooll in The Forgotten Colony (1999), are the first manifestations of Anglo-Argentine or "Southamericana" literature (1999:205). They will be studied together with more recent expressions: the electronic publications, namely, Buenos Aires Review and Tenso Diagonal. We aim at comparing and contrasting the above-mentioned intercultural manifestations, analysing how they show anglophony, what role the translation process plays, and based on such analysis, defining the intercultural configuration wherein said manifestations originate.

In this paper, we argue for the inclusion of archaeology in discussions about how humans have contributed to and dealt with climate change, especially in the long term. We suggest Niche Construction Theory as a suitable framework to that end. In order to take into account both human and environmental variability, we also advocate for a situated perspective that includes the Global South as a source of knowledge production, and the Neotropics as a relevant case study to consider. To illustrate this, we review the mid-Holocene Hypsithermal period in the southern Puna and continental Patagonia, both in southern South America, by assessing the challenges posed by this climate period and the archaeological signatures of the time from a Niche Construction Theory perspective. Finally, we emphasize the importance of these considerations for policymaking. This article is part of the theme issue 'Climate change adaptation needs a science of culture'. [ABSTRACT FROM AUTHOR]

ECOTOURISM ,ENVIRONMENTAL management ,NATURE conservation ,PROTECTED areas ,PRIVATE sector - Abstract
In this paper, we mobilise a multiple environmentalities framework that captures overlapping rationalities of governing nature to engage and identify the role of maps and mapping practices in Patagonia-Aysén, Chile, a peripheral region where government and institutional actors have embraced (eco)tourism as a conservation strategy in protected areas. Through interviews with key stakeholders situated in conservation and tourism institutions in both the public and private sector, we identify two dominant environmentalities at play in the relationship between protected area management and tourism development in Patagonia-Aysén: a neoliberal environmentality, which seeks to promote conservation through the commodification of nature as a tourism product, and an environmentality of truth predicated on a singular, pristine and beautiful nature as an object of conservation and advantage for tourism. Through an analysis of conservation maps and mapping rationalities specific to the Cerro Castillo protected area in Patagonia-Aysén, we trace how these multiple environmentalities are consolidated, rendered real and actionable through geovisualisations and cartographic practices. We argue that conservation maps and mapping emerge as an 'encounter point' wherein multiple environmentality strategies and rationalities converge, producing a form of governing the spaces of conservation – what we term a spatial environmentality – rooted in neoliberal and aesthetic logics. Spatial environmentality, we contend, constitutes a form of governing conservation spaces by inscribing and assigning (in)appropiate uses to nature that operationalises institutional interests in conditioning the active engagement of 'environment subjects' to control, administer, and take care of the spaces of conservation while in turn making environmental stewardship profitable.

This paper presents the results of a study on the isotopic ecology of guanacos in central western Argentina. We examine the historical population ecology of guanacos using stable isotope analysis of bone collagen from pre-Hispanic and modern guanaco populations (n = 129), considering variability in two ecoregions: the Monte hot desert and the Andean-Patagonian cold desert. Our study addresses the consistency of guanaco diets over time, evaluating palaeoecology to provide information for conservation of this taxon. We found significant differences in isotopic niche size between modern and archaeological guanacos. When analyzed by ecoregion, there were significant differences in niche size through time, indicating that guanacos had distinctive dietary habits and occupied different ecological niches across the ecoregions. Comparing Standard Ellipse Areas (SEA) through time and across space, we observed that the archaeological SEA for guanacos is smaller than its modern counterpart in the Andean-Patagonia ecoregion. Conversely, in Monte, the archaeological SEA is larger than the one established for modern samples. The contrast between pre-Hispanic and modern populations highlight the impact of human activity and conservation efforts on the distribution and ecology of guanacos. These findings have important implications for understanding guanaco ecology with consequences for conservation policies. [ABSTRACT FROM AUTHOR]

Bunicontro, M.P. and Marcomini, S.C., 2021. Geomorphological evolution of the Patagonian coast surrounding the Golfo Nuevo (Chubut, Argentina) during Late Quaternary: Overview and new proposal. Journal of Coastal Research, 37(3), 528–543. Coconut Creek (Florida), ISSN 0749-0208. The main contribution of this paper is a new interpretation of the geomorphological evolution of the North Patagonian coast surrounding the Golfo Nuevo from Mid-to-Late Pleistocene until present. The proposed model shows how continental and marine landforms evolved during the Late Quaternary. According to this, the Golfo Nuevo depression formed during the Middle Pleistocene (>130 ka) above previous fluvial terraces, which are attributed to different stages of the Chubut river. Several pediment types and levels were also identified: (1) flanking pediment (level 1) associated with an ancient fluvial valley; (2) convergent pediment related to a previous depression of Golfo Nuevo (level 2), both assigned to Middle Pleistocene; and (3) a littoral pediment (level 3) linked to a Holocene highstand level. The height and position of accretion marine terraces are discussed, in addition to their previous dating. It can be assumed that Golfo San Matías was flooded twice as a consequence of marine transgressions (marine isotopic stage [MIS] 5 and MIS 1). Likewise, Golfo Nuevo and Golfo San José were affected only once, during the maximum Holocene transgression (MIS 1). This paper highlights the importance of reconstructing the geomorphological evolution of a coastal area of the Patagonia as a result of a combination of changes linked to sea-level variations (mainly associated with glacio-eustasy) and climate, paleo-shorelines records, and continental landforms through Late Quaternary. The proposed geomorphological model can be considered a novelty because of the complex integration of continental and marine landforms and the study of their relative relation. [ABSTRACT FROM AUTHOR]

Background: By using a historical approach we attempt to answer the question of whether the "dogs" of Fuegian and Patagonian peoples are a domesticated dog (Canis lupus familiaris) or a tamed or domesticated Culpeo "fox" (Lycalopex culpaeus), or a cross breed. Methods and results: We reviewed historical chronicles and current scientific papers, and clarified several rather confusing concepts, providing disambiguation for terms such as Magellanic region, Patagonia, and Tierra del Fuego; Fuegian and Patagonian peoples; and Fuegian and Patagonian dogs. We conclude that these dogs belong to two different canid varieties: The smaller domestic dog typical of the "canoe-indians" (Chonos, Kawesqar, and Yahgan peoples) and the larger tamed or domesticated Culpeo "fox" typical of the "foot indians" (Aonikenk, Manek'enk, and Selk'nam peoples, thus proposing the use of Fuegian and Patagonian dog, respectively. Discussion: We think that the original Fuegian dog was indeed a Canis lupus familiaris brought along by the natives after the Bering's crossing and that the Patagonian dog was a tame Culpeo fox Lycalopex culpaeus, which was progressively replaced by the more gregarious, human friendly, and colorful domestic dogs brought by European explorers, adventurers, colonizers, and settlers of Patagonia and Tierra del Fuego during the mid to late 1800s. The possibility that the Patagonian dog was a cross between domestic dog and Culpeo "fox" cannot be ruled out, but the only specimen genetically analyzed was closest to being the latter and not a hybrid.

In this paper, we study natural hazards and their potential impacts on productive activities in the Comau Fjord in Chilean Northern Patagonia. We carried out hazard mapping to identify areas with evidence of geomorphological activity on slopes in terms of landslides, river/tsunami flooding, and glacial retreat. The assessment of different geomorphic processes was carried out by both detailed fieldwork and analysis of satellite remote sensing and aerial photography information. We identified terrain units that are subject to multi-hazards overlapping different spatially distributed hazard maps. This information was overlaid with spatial data of economic activities in the area in order to establish the impacts of the natural hazards on the local salmon and mussel farming infrastructure (risk). The results suggest significant exposure levels for these productive activities and potential damage due to the occurrence of natural hazards. The extension of a major highway (CH-7 Austral Highway) on the east coast of the Comau Fjord will be a new incentive for economic development in the area. However, the highway construction sites show a high level of exposure to natural hazards, especially floodings and landslides. Our study highlights that the geohazard potential might have a high negative impact on future productive activity in the fjord as well as on the new highway infrastructure. [ABSTRACT FROM AUTHOR]

The Salado and Verde streams constitute the two main seasonally available freshwater courses that flow into the Atlantic coast of the Río Negro province (continental Patagonia, Argentina, 42° South). This would have favored their use in the past as corridors for human circulation between the coast and the interior. This paper presents the results of the technomorphological and geochemical analyses of the obsidian artifacts recovered in the area to constrain mobility. The results allow us to propose the existence of toolkit reconditioning or replacement activities, and the identification of different sources of provenance of the obsidians (Sacanana, Telsen, and Portada Covunco, distant up to 800 km from the study area), reinforcing the hypothesis of a coast–inland circulation, with the possible existence of circuits of exchange of this raw material.

Many of the species used in family farming systems (FFS) in Patagonia belong to the group known as neglected and underutilized species (NUS), which promote biocultural diversity and contribute to food sovereignty. Due to the scarce attention paid to NUS by agronomic sciences, little is known about their biotic pollination, although it is a well-studied aspect for commercially important plants. We evaluate the contribution of animal pollination to NUS managed by Patagonian FFS. We present a literature review of the NUS used and aspects related to their pollination and floral visitors, for which 725 papers were reviewed. FFS use 426 NUS (414 angiosperms, 10 gymnosperms and 2 ferns). Most NUS (86.7%) depend to some extent on animal pollination, either for the production of fruits or seeds that are harvested for consumption (direct dependence, 35%) or for obtaining seeds (indirect dependence, 65%), which in many cases are necessary for reseeding. Gathering and cultivation are the most common management practices for these species. Hymenoptera and Diptera are the animals that contribute most to NUS biotic pollination. Our results show that animal pollination is a key contribution of nature to sustain cultural aspects and food sovereignty of FFS in Patagonia. [ABSTRACT FROM AUTHOR]

Safety and environmental aspects are crucial beyond production goals in the hydropower industry. By monitoring landslides associated with the construction of a hydropower dam in the Santa Cruz River in Argentine Patagonia, this paper contributes to the assessment of the project structural integrity of the construction and safety risks. Ground deformation is monitored using synthetic aperture radar (SAR) satellite data and the persistent scatterer interferometry technique, and it is contrasted with optical imagery, geological and technical reports, and fieldwork. The results include maps of accumulated deformation and deformation time series for the locations of the anchorages of the dam, providing a new and independent dataset to assess the integrity of the construction.

Bioarchaeological research of bone growth patterns provides information on the health status and disease of past populations. Recent studies have pointed out the potential of metric analysis of nonadult vertebrae as indicators of stress during different stages of ontogeny, highlighting that most vertebral measurements present low sexual dimorphism, a stable and known pattern of growth and give useful information even in incomplete spines. The aims of this paper are first, to construct a vertebral growth profile for nonadults of a skeletal series of Patagonian Late Holocene hunter‐gatherers from Salitroso Lake (SAC); second, to compare it to the ones obtained in other archaeological and modern populations with different stress experiences; and third, building on this, to assess whether individuals with evidence of stress experienced in early development demonstrate different patterns in vertebral growth than those without. Two spinal dimensions are used: vertebral body height (VBH) and transverse diameter of the neural canal (TDNC) in a sample of 23 nonadult skeletons with ages previously estimated from dental and bone indicators. The vertebral dimensions of 20 adults between 18 and 35 years of age were also measured as reference information. Results show that the growth of the VBH is steady over the years and reaches adulthood size by approximately 16 years of age whereas TDNC dimensions do not experience marked fluctuations in size throughout life and adult dimensions are reached at approximately 4 years of age as expected. The vertebral growth pattern observed in SAC is similar to that obtained in other archaeological samples from very different settings but experiencing relatively high nutritional or pathological stress in early stages of life. However, it is markedly different, and systematically smaller, to the 20th century sample pattern, probably responding to a secular trend in the modern population with a more stable access to resources and medical treatment. Finally, SAC individuals with systemic stress markers do not tend to exhibit smaller vertebral dimensions than those without them. [ABSTRACT FROM AUTHOR]

Ombrotrophic bogs in southern Patagonia have been examined with regard to paleoclimatic and geochemical research questions but knowledge about organic matter decomposition in these bogs is limited. Therefore, we examined peat humification with depth by Fourier Transformed Infrared (FTIR) measurements of solid peat, C/N ratio, and δ
13 C and δ15 N isotope measurements in three bog sites. Peat decomposition generally increased with depth but distinct small scale variation probably caused by environmental changes occurred. C/N ratios varied mostly between 40 and 120 and were significantly correlated (R² > 0.55, p < 0.01) with FTIR-derived humification indices. The degree of decomposition was lowest at the site with the least sea spray input, while the peat was most decomposed at the driest site with highest sea spray deposition. Decomposition of peat was also advanced near ash layers. Values of δ13 C were 26.5 ± 2‰ in the peat and partly related to decomposition indices, while δ15 N in the peat varied around zero and did not consistently relate to any decomposition index. Concentrations of DOM partly related to C/N ratios, partly to FTIR derived indices. DOM was enriched in13 C and in15 N relative to the solid phase probably due to multiple microbial modifications and recycling of N in these N-poor environments. In summary, paleoclimatic signals may have influenced decomposition according to depth profiles of C/N ratios, δ13 C values, and FTIR spectra, but the study also suggests that decomposition was also influenced by ash layers, sea spray input and other site specific factors.

Livestock grazing modifies and even degrades arid ecosystems, which threatens the sustainability of livestock farming itself. It is essential to learn more about the effects of grazing on vegetation and soil to design strategies to avoid desertification, perhaps the most serious problem faced by drylands. In this paper, we evaluate the changes in the functional traits of the plant community and the biological soil crust induced by the intensification of grazing in Patagonian ecosystems. This description, together with changes in diversity, plant composition, and ecosystem functioning, can help us to understand the mechanisms by which the intensification of sheep grazing could degrade arid ecosystems.

SONGS ,LANGUAGE ability ,EMIGRATION & immigration - Abstract
Over the centuries there have been a number of attempts, for economic, political and religious reasons, to create Welsh settlements overseas. The most successful of these, in terms of longevity at least, and perhaps the best known of all Welsh emigration ventures, was the establishment in 1865 of a Welsh Settlement in Patagonia, in what is now the Province of Chubut in Argentina, where perhaps as many as 5,000 of the inhabitants still speak Welsh fluently or have some ability with the language. The preservation of Welsh identity was central to the Patagonian project, which aimed to create a new Welsh-speaking, self-governing Wales overseas, founded on Christian and democratic principles. From the outset, songs played an important role in fostering the ideals that inspired the founders of the Settlement, ideals that would come progressively under threat as the Argentine government increasingly asserted its authority over the Settlement, promoting Argentinian identity and replacing Welsh with Spanish as the medium of education. This paper gives an overview of the development of the Welsh Settlement in Chubut down to the present day, focussing especially on the role of song in nurturing the dream of the Settlement's founders.

Patagonian shrub and ecotonal communities were sensitive to past environmental changes and thus may also be affected by future ones. Therefore, their paleoecological study constitutes a valuable tool to understand the way in which these plant communities respond to the forcings responsible for environmental variability. The aim of this paper is to reconstruct the vegetation dynamics of the Pueyrredón Lake area (47°25′55′′ S; 72°0.7′7′′ W) for the last 3000 cal yr BP and to contextualize these changes in a regional paleoclimatic framework. The results indicate that at the beginning of the 2900 cal yr BP, the vegetation in the northwest of Santa Cruz, Argentinian Patagonia, was represented by a grass-shrub steppe associated with forest–shrub steppe ecotonal elements. This information correlates with the larger-scale environmental inferences described for the period, which indicate an increase in moisture availability due to the weakening of the westerly winds. A marked change to arid conditions is indicated in the last 1050 cal yr BP, with the establishment and development of different shrub steppe communities and the lack of ecotonal elements. Although vegetation was sensitive to changes in moisture conditions related to the variability of the westerly winds, there is evidence of differences in the composition of shrub vegetation regarding the sequences analyzed. Variations in pollen proportions of the shrub steppes in the Pueyrredón Lake area suggest that changes in vegetation are not only due to climate variability but also local factors in the areas where shrub communities grow. The integration of the information with other Patagonian sequences allowed to frame these changes in a regional context. The results obtained provide useful information to understand the way vegetation changed in the past and the manner in which it may respond to future changes. [ABSTRACT FROM AUTHOR]

Skorpiovenator bustingorryi is a derived abelisaurid theropod represented by a fairly complete skeleton from the Late Cretaceous sedimentary beds of north-western Patagonia. Although some features were described in the original paper, mainly related to the skull, the appendicular anatomy remains undescribed. The aim of the present contribution is to provide a detailed description and analysis of the available appendicular bones, including comparisons with other ceratosaurian theropods close to Skorpiovenator. In this way, new autapomorphies emerged to further distinguish Skorpiovenator from its relatives. Furthermore, a comprehensive phylogenetic analysis was performed and several characteristics of the hind limb, in particular some of the autopodium, resulted in the identification of new apomorphic traits for Ceratosauria and Abelisauridae. These features might prove to be useful for future phylogenetic analyses and may help to resolve the still confusing and debated internal relationships of abelisaurid theropods.

The classic approach to research on toponymy is limited to a linguistic focus. This reductionism has had a negative impact on the study of the toponymy of intercultural and indigenous territories, as in the case of the northern Patagonia. Based on a two-year ethnographic study in northern Patagonia, this article analyzes the socio-spatial dimension of Mapuche toponymy, through a mixed methodology involving both data collection and analysis, and an ethnographic approach. The article analyzes how these toponyms emerge from a variety of socio-spatial practices and meanings that are not only intertwined, but also involve several social, environmental, and political dimensions. We argue that the study of indigenous toponymy as a space-time compression entails an ontological opening of toponymy based on the process of inhabiting place. In this regard, the paper discusses the importance of understanding indigenous toponymy as a historically situated process. [ABSTRACT FROM AUTHOR]

This paper presents for the first time results on winds, tides, gradients of horizontal winds, and momentum fluxes at mesosphere and lower thermosphere altitudes over southern Patagonia, one of the most dynamically active regions in the world. For this purpose, measurements provided by SIMONe Argentina are investigated. SIMONe Argentina is a novel multistatic specular meteor radar system that implements a Spread‐spectrum Interferometric Multistatic meteor radar Observing Network (SIMONe) approach, and that has been operating since the end of September 2019. Average counts of more than 30,000 meteor detections per day result in tidal estimates with statistical uncertainties of less than 1 m/s. Thanks to the multistatic configuration, horizontal and vertical gradients of the horizontal winds are obtained, as well as vertical winds free from horizontal divergence contamination. The vertical gradients of both zonal and meridional winds exhibit strong tidal signatures. Mean momentum fluxes are estimated after removing the effects of mean winds using a 4‐h, 8‐km window in time and altitude, respectively. Reasonable statistical uncertainties of the momentum fluxes are obtained after applying a 28‐day averaging. Therefore, the momentum flux estimates presented in this paper represent monthly mean values of waves with periods of 4 h or less, vertical wavelengths shorter than 8 km, and horizontal scales less than 400 km. Key Points: First observations of mesosphere and lower thermosphere dynamics over one of the most dynamically active regions in the worldEstimates of mean horizontal winds and their gradients are possible, thanks to the multistatic configurationMean momentum fluxes are estimated with vertical velocity estimates free of horizontal divergence contamination [ABSTRACT FROM AUTHOR]

Understanding the use of natural corridors is critical for characterizing the past use of marginally occupied landscapes at the Andean fringes of western Patagonia by the hunter-gatherer groups who inhabited this region. In this paper, we combine least-cost path models and archaeological surveys and excavations to determine the possible movements along the southern margin of General Carrera Lake. The methodology includes defining uncertainties that allow for modeling a set of equiprobable routes, thereby avoiding problems with errors and biases from predictors, such as slope, land-use cover, and seasonality. The results identify mobility corridor bottlenecks, i.e., geographical areas with a high probability of travel routes with equiprobable routes that converge. In addition, we identify areas where travel routes are likely to diverge into multiple semi-parallel routes. The study of archaeological sites provides stratigraphic data to control for the chronology and characteristics of mobility along this transect. The correlation between archaeological sites and paths, specifically for the control and winter scenarios, shows the quality of these route predictions. These results indicate the repeated use of internodal spaces that were effectively incorporated into mobility during the last three millennia. [ABSTRACT FROM AUTHOR]

The distribution of vos 'you' and uno 'one' in generic messages is studied in a corpus of female speakers of Spanish (Argentina).The question was how it is possible that the form vos , so clearly defined as the pronoun to refer to the interlocutor, could have an impersonal reading, alongside the indefinite pronoun uno , which seems much more fit to do the job. The alternation between the generic use of the forms vos and uno cannot be, in our view, the result of chance nor a merely stylistic tool, but corresponds to the communicative strategies that speakers utilize in each and every context. This paper studies the different factors that play a role in the selection of each of the pronouns. • Vos 'you' and uno 'one', used in generic messages, have different meanings, resulting in different interpretations. • Linguistic forms have single meanings, but may have different interpretations in different contexts. • The single meaning is a clue for a given interpretation. • Generic vos 'you' refers to the hearer: 'you in my place'. •Generic uno 'one' refers to the speaker: '(some)one like me'.

Nowadays, wildlife is one of the most important sources of zoonoses, and it is a major concern for public health. Nevertheless, little is known about the role of wildlife as a reservoir and source of infectious diseases in the past. South America presents a wide diversity of wildlife. In the south of the continent, Argentina shelters a large diversity of neotropical carnivores. Although the paleoparasitological studies on carnivores have been increasing in southern Argentina, most of the efforts have been focused in a handful of sites located in western Patagonia. In this paper, two coprolites of felid found in Cueva Galpón, an initial late Holocene mortuary site from northeast Patagonia (Argentina), were studied for paleoparasitological purposes. Samples were processed by rehydration and homogenization, filtered and processed by spontaneous sedimentation. The samples were assigned to Puma concolor (puma) or Panthera onca (jaguar). Microscopic observations revealed that both coprolites were positive for parasite remains. High parasite richness was observed. Six nematodes, one cestode, and one coccidian morphotypes were reported. This is the first time that Gnathostoma sp. and Spirocerca sp. were recovered from holocenic times from Patagonia. This finding implies that some diseases such as taeniasis, spirocercosis, gnathostomosis, ascariasis, and coccidiosis could be present in holocenic wildlife from Patagonia prior to the Spanish colonization and domestic animal introduction. The overall results suggest that felids could have played a role as reservoirs and source of some parasitic species, some of which are zoonotic. Therefore, this animal could have entailed a risk agent for human health in the site. [ABSTRACT FROM AUTHOR]

This paper presents the first petrographic study of pottery made by hunter–gatherer societies that inhabited the eastern Pampa–Patagonia transition regions (Buenos Aires province, Argentina), between c.1900 and 400 radiocarbon‐years bp. The data show that the potters maintained technical choices during this period as part of a technological tradition. With this common knowledge, local fabric recipes coexisted linked to the regularity of the use of raw materials in accordance with the geology of the research area. Furthermore, the finding of archaeological clay doughs would indicate the in situ production of vessels in the residential contexts of these pre‐Hispanic populations. [ABSTRACT FROM AUTHOR]

Adult late-LL learners are the main source of participants for research on utterance fluency. Although there are ample opportunities to study these learners, bilinguals who come from a more diverse background are under-researched. This paper investigates the effects of long-term bilingualism on the second-language fluency patterns of a community of LL-Afrikaans/LL-Spanish bilinguals residing in Patagonia, Argentina. These third-generation bilinguals are dominant in their LL and are undergoing LL attrition. The acoustic analysis draws from a corpus of Spanish sociolinguistic interviews obtained from the bilinguals, who were compared to Spanish monolinguals on speed, breakdown, and repair fluency. For some measures (mean-syllable duration and phonation-time ratio), the bilinguals performed similarly to the Spanish monolinguals, whereas for other measures the results were mixed: the bilinguals produced less filled pauses, but used longer silent pauses and more reformulations, than the monolinguals. These outcomes are theorized within current models of LL-speech production. [ABSTRACT FROM AUTHOR]

Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative paths toward sustainability in agricultural production. Argentina is ranked second in the world in terms of land under organic certification. Extensive sheep production in Patagonia natural grasslands accounts for most of this area and harvested organic area remains a very small fraction of total harvested land (0.6%). This paper aims to contribute to the discussion of opportunities and limitations in organic farming as an ecological intensification alternative for Argentina's Pampas. A case study was conducted on Pampa Orgánica Norte. This is a group of nine organic farmers that manages field crops and livestock-certified organic production. Farmers interviewed in this study considered different criteria including economic and environmental attributes when choosing to produce organically. However, the main drivers for conversion to organic production are related to environmental factors, in particular ecosystem protection. The main limitations in organic production are related to crop management practices, primarily weed control. To achieve the goal of increasing organic production a more active role of the public sector in technology generation and transfer was demanded by farmers. [ABSTRACT FROM AUTHOR]
