Keystone communities can rescue aquatic metacommunities influenced by pesticide contamination. [PDF]

Ecol Appl
Abstract Pesticide contamination in freshwater habitats is a major global issue, affecting water quality, biodiversity, and ecosystem services. Uncontaminated habitats embedded in agricultural landscapes might act as keystone communities, with the ability to restore diversity and ecological processes in contaminated sites through dispersal.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Amid the fallen leaves: Intense collecting in the Northern Atlantic Forest reveals new minute harvestmen species (Opiliones: Stygnidae) within the Area of Endemism of Pernambuco

Austral Entomology, Volume 64, Issue 4, November 2025.
Abstract Stygnids represent one of the most diverse harvestman families, with many endemic species in the Area of Endemism of Pernambuco, a pattern increasingly evident by intensified sampling in the region over the years. The area is also recognised for hosting a group of understudied minute leaf‐litter dwellers stygnids, represented by the following ...

Mapping Resilient Landscapes to Climate Change in a Megadiverse Country

Global Change Biology, Volume 31, Issue 10, October 2025.
Our mapping of terrestrial climate‐resilient sites for biodiversity across Brazil identifies sites with greater chances of providing suitable conditions for species to persist under regional climate change. Landscape resilience information has the potential to be used to effectively guide decision‐making and public policy on strategies for conservation,
