Antarctic Toothfish in the South Orkney Islands: Using Otolith Chemistry to Test Current Hypotheses About Nursery Areas and Demographic Units.

We used otolith chemistry to test and complement current hypotheses regarding habitat use and connectivity between sub-populations in Area 48 of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Sagittal otoliths from 45 fish sampled near the South Orkney Islands were analysed. Their elemental (Li, Na, Mg, Cr, Mn, Sr, Sn, and Ba relative to Ca) and isotopic (δO and δC) signatures were examined in both the nuclear and marginal regions, representing juvenile and adult stages.

The Chilean COVID-19 Genomics Network Biorepository: A Resource for Multi-Omics Studies of COVID-19 and Long COVID in a Latin American Population.

Although a lack of diversity in genetic studies is an acknowledged obstacle for personalized medicine and precision public health, Latin American populations remain particularly understudied despite their heterogeneity and mixed ancestry. This gap extends to COVID-19 despite its variability in susceptibility and clinical course, where ethnic background appears to influence disease severity, with non-Europeans facing higher hospitalization rates. In addition, access to high-quality samples and data is a critical issue for personalized and precision medicine, and it has become clear that the solution lies in biobanks.

Social-ecological resilience: Knowledge of agrobiodiversity by campesinos and migrants in the face of global changes.

There is concern that agrobiodiversity is being irreversibly eroded in the face of agricultural industrialization. While academic and policy debates stress loss of landraces, little attention has been paid to evaluating how agricultural knowledge systems endure in response to broader social-ecological changes (i.e.

Seasonal Hair Glucocorticoid Fluctuations in Wild Mice () within a Semi-Arid Landscape in North-Central Chile.

Mammals in drylands face environmental challenges exacerbated by climate change. Currently, human activity significantly impacts these environments, and its effects on the energy demands experienced by individuals have not yet been determined. Energy demand in organisms is managed through elevations in glucocorticoid levels, which also vary with developmental and health states.

Mountain social-ecological resilience requires transdisciplinarity with Indigenous and local worldviews.

Addressing the shocks of global crises requires that scientists, policymakers, and Indigenous Peoples and Local Communities work together to enable communities to withstand and adapt to disturbances. On the basis of our experiences in the Andes, we propose the '10-step cycle of transdisciplinarity' for designing projects to build social-ecological resilience in mountains.

"The climate itself must have hidden some medicines": traditional veterinary medicine of indigenous and non-indigenous campesinos of the southern Andes.

Background: Traditional veterinary medicine (TVM) or ethnoveterinary medicine comprises knowledge, practices, and beliefs about farm animals. Its study serves to offer ecologically and culturally appropriate strategies for the management of animals and their health in a context marked by the increased use of synthetic pharmaceuticals, social-environmental degradation, pollution, and climate change. In this study, we examine the TVM that Mapuche and non-Mapuche campesinos in the southern Andes have about the management of animals and their health.
