Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Prevalence of traded bird species in key biodiversity areas

Conservation Biology, EarlyView.
Abstract The use and trade of biodiversity involve tens of thousands of species that are exploited at a range of scales, intensities, and degrees of sustainability. As a result, some are highly threatened. Key biodiversity areas (KBAs) are sites of significance for the persistence of biodiversity identified nationally based on standardized criteria ...

Patterns of frequency and abundance of plant dispersal systems in Colombian forests and its relationship with the geographical regions of the country

Colombia Forestal, 2013
The study of plant dispersal systems allows to go in depth in aspects that define the regeneration of forests, being essential to understand not only the population dynamics of plants but also the ecological relationships that emerge within ecosystems ...

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Beyond the Kidney and Lung: Cutaneous and Mucosal Clues to Human Hantavirus Disease

International Journal of Dermatology, EarlyView.
Rodent exposure and aerosolized excreta can lead to hantavirus infection with systemic endothelial injury and capillary leak, resulting in thrombocytopenia and syndromes such as HPS/HCPS and HFRS/NE. Early dermatologic and mucosal findings, including flushing, conjunctival injection, petechiae/purpura, and mucosal bleeding, may provide important clues ...

El Pastaza y el Upano, dos ríos tropicales que conectan los Andes a la Amazonía

Revista del Museo de La Plata, 2019
El Amazonas, llamado Marañón aguas arriba, nace en los Andes y se alimenta de los manantiales de la cordillera y los sedimentos arrancados a las laderas de la montaña. Los valles del Pastaza y del Upano son cabeceras de ríos que alimentan al Marañón.
