Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

Functional Ecology, EarlyView.
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 ...

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

As variações na comunidade de Odonata (Insecta) em córregos podem ser explicadas pelo Paradoxo do Plâncton? Explicando a riqueza de espécies pela variabilidade ambiental

, 2013
A teoria do Paradoxo do Plâncton postula que ambientes que apresentam flutuacoes temporais periodicas apresentariam alta diversidade de especie, uma vez que essas flutuacoes impediriam a ocorrencia da exclusao competitiva.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
