Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

Functional Morphology of the Scaphoid in Extant African Apes, Humans and Fossil Hominins

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives The morphology of the hominoid scaphoid has played a key role in functional and evolutionary hypotheses related to the emergence of hominin bipedalism and tool use. However, the scaphoid's complex morphology is challenging to comparatively analyze via traditional 2D linear measurements.

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

People and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

Predictions of southern migration timing in coastal sharks under future ocean warming

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...
