Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Tracing Human Diversity in South America's Southern Cone: Linguistic, Morphometric, and Genetic Perspectives Explorando la Diversidad Humana en el Cono Sur de América del Sur: Perspectivas Lingüísticas, Morfométricas y Genéticas

American Journal of Biological Anthropology, Volume 187, Issue 3, July 2025.
ABSTRACT Objectives Studying the relationship between biological and cultural diversity can lead to rich insights into human history. South America has been relatively neglected in this kind of work, even though it intriguingly exhibits unexpectedly high biological and cultural diversity.

Direct and indirect effects of roads on activity patterns of the largest South American artiodactyl (Lama guanicoe) in a hyper-arid landscape

Mammalian Biology, 2020
The effects of roads on natural environments have been studied in many places around the world. The presence of roads can be considered for native animals as a disturbance stimulus.

Different factors that modify anti-predator behaviour in guanacos (Lama guanicoe)

Acta Theriologica, 2014
Animals optimize the trade-off between the cost of not fleeing and the benefits of staying because the factors that influence flight decisions and the disturbance level of a particular stimulus can vary both spatially and temporally. Different factors (human impact and habitat characteristics) likely to modify anti-predator behaviour in different types

Gloger's Rule or Historical Conjecture? Tests in Mammals

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Ecogeographical rules for animal coloration include Gloger's rule, which states that homeotherms are darker at lower latitudes; however, 19th‐century naturalists observed that animals are more colourful in the tropics. We investigated these ideas across the head, torso, legs and tail regions of 2726 species of terrestrial mammals using phylogenetic ...
