Ecological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.

Vertebrate diversity and biomass along a recovery gradient in a lowland tropical forest
Biotropica, Volume 57, Issue 1, January 2025.Deforestation of tropical forests has resulted in large areas of secondary forests with the potential for biodiversity to re‐establish to levels usually found in old‐growth forests. This study shows that diversity and biomass of mammals and birds in regenerating forests can recover to old‐growth levels within a relatively short time.

Journal of Applied Ecology, Volume 61, Issue 10, Page 2497-2509, October 2024.To minimise the loss of avian phylogenetic diversity and functional traits from farming in the Amazon, it is imperative to protect large blocks of undisturbed and regenerating forests. The intensification required within existing farmlands to make space for spared lands while meeting agricultural demand needs to be sustainable, avoiding long‐term ...

Animal Conservation, Volume 27, Issue 4, Page 507-521, August 2024.We evaluated the viability of a newly founded population of the endangered Gran Canaria blue chaffinch (Fringilla polatzeki). We performed a multiple trait assessment of genetic, body condition and breeding success data. Our findings suggest that the translocation program has been successful and provide insights on the effectiveness of the actions ...

Functional Ecology, Volume 38, Issue 6, Page 1407-1419, June 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Current global change scenarios demand knowledge on how anthropogenic impacts affect ecosystem functioning through changes in food web structure. Frugivorous mesocarnivores are a key link in trophic cascades because, while their abundance and behaviour are usually ...
