Community‐level effects of Müllerian mimicry on pollinator diversity and functioning
Functional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Journal of Animal Ecology, Volume 95, Issue 3, Page 553-569, March 2026.This original research piece demonstrates, through empirical and theoretical modelling approaches, that the epibionts of striped dolphins indicate dolphin abundance shifts caused by epidemics of dolphin morbillivirus (DMV). In addition, we provide the first SIR model to investigate the epidemiology of DMV in western Mediterranean striped dolphins ...
