Drought effects in Mediterranean forests are not alleviated by diversity‐driven water source partitioning

Journal of Ecology, Volume 112, Issue 9, Page 2107-2122, September 2024.
Tree species diversity promotes below‐ground water source partitioning in mixed oak and pine stands, potentially reducing competition for water in more diverse ecosystems. Yet, these results show that it is insufficient to buffer the adverse impacts of severe droughts on above‐ground tree carbon and water use, leading to higher water stress, especially

Descrição e fatores modeladores da dieta e ecologia da alimentação de girinos neotropicais: Um estudo de caso e uma revisão abrangente

Austral Ecology, Volume 49, Issue 1, January 2024.
Resumo Os girinos são componentes importantes de muitas teias alimentares aquáticas, pois influenciam as populações em outros níveis tróficos e, consequentemente, a transferência de energia entre os ecossistemas aquáticos e terrestres. O que os girinos consomem é um fator chave para suas funções ecológicas. As assembleias de anuros neotropicais incluem
