Key drivers of at‐vessel mortality in demersal sharks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone
Ecology and Evolution, Volume 15, Issue 9, September 2025.We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Urban developmental environments alter tadpole phenotypes depending on origin
Journal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Escribir en comunidad: Construcción de relaciones y responsabilidad en la producción de conocimiento
American Anthropologist, Volume 127, Issue 3, Page 447-465, September 2025.ABSTRACT As anthropology reckons with its past, present, and future, anthropologists increasingly seek to challenge inequities within the discipline and academia more broadly. Anthropology, regardless of subdiscipline, is a social endeavor. Yet research often remains an isolating (though not necessarily solitary) process, even within research teams and

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes
Ecology and Evolution, Volume 15, Issue 8, August 2025.Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...
