Models Incorporating Non‐Stationarity Improve Detection of Climate‐Driven Range Shifts in Odontocetes

Diversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Climate change is causing distributional shifts in many species globally. identifying and anticipating these shifts is critical to understanding ecosystem impacts and implementing successful management strategies. species distribution models (SDMs) are useful tools often employed to describe current and changing habitat use, particularly ...

Comparative Analysis of the Whistles of Three Oceanic Dolphins in the Comoros

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Shisiwani National Park (Anjouan, Comoros) is a cetacean biodiversity hotspot. However, the vocal behavior of marine mammals inhabiting the area has never been studied. In 2023, we conducted a 400‐nautical‐mile survey from a 5‐m motorboat to determine their presence.

Close encounters of the friendly kind: pacific between‐group interactions in primates

Biological Reviews, Volume 100, Issue 6, Page 2257-2284, December 2025.
ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.
