Same‐sex partnerships in birds: a review of the current literature and a call for more data

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
Same‐sex sexual behaviour (SSB), encompassing actions such as courtship, pair bonding, and parenting between individuals of the same sex, has been observed across numerous taxa, including birds. Yet despite its widespread occurrence, SSB remains poorly understood, often dismissed as maladaptive or the result of errors in sex discrimination.

Anthropogenic disturbances alter the trophic niche structure and ecological relationships of understory bat communities in the Ecuadorian Andean Chocó

Wildlife Biology, Volume 2025, Issue 3, May 2025.
Human disturbances have reduced the three basic niche dimensions for the survival of some mammalian species (space, time, and resources). Anthropic activities cause the extinction of ecological functionalities faster than species extinctions. In this study, we identified four types of habitats in the Ecuadorian Andean Chocó: primary forest (PF ...

A Dryopithecine Talus From Abocador de Can Mata (Vallès‐Penedès Basin, NE Iberian Peninsula): Morphometric Affinities and Evolutionary Implications for Hominoid Locomotion

American Journal of Biological Anthropology, Volume 186, Issue 4, April 2025.
ABSTRACT Objectives The functional interpretation of postcranial remains of Middle Miocene great apes from Europe (dryopithecines) suggests a combination of quadrupedalism and orthograde behaviors without modern analogs. We provide further insights based on an isolated dryopithecine talus (IPS85037) from the Middle Miocene (11.7 Ma) Abocador de Can ...

Long‐term interventions by conservation and development projects support successful recovery of tropical peatlands in Amazonia

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.
