Global Change Biology, Volume 32, Issue 1, January 2026.(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Ecology of Freshwater Fish, Volume 34, Issue 4, October 2025.ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and

Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT Stream ecosystem functioning and community structure are influenced by local and catchment land use. In mosaic landscapes, agricultural activities can also affect leaf breakdown and detritivore assemblages in downstream forest reaches. We evaluated the combined effects of upstream deforestation and the input of a nonnative crop species on leaf

Ecological Entomology, Volume 50, Issue 4, Page 595-608, August 2025.The two most diverse beetle families, Staphylinidae and Curculionidae (black arrows), have fewer studies of diversity and elevation than expected, while the Carabidae and Scarabaeidae (brown arrows) are overstudied. Dung beetle (Scarabaeidae) phylogenetic and taxonomic diversity decreases with elevation along tropical and temperate elevational ...
