The Influence of Dominant Habitats on Termite Species Diversity and Community Structure in the Brazilian Savanna

open access: yesAustral Ecology, Volume 50, Issue 12, December 2025.
We investigated the diversity and composition of termites across various habitats in the Brazilian Savanna. Studies like the one presented here enhance our understanding of the relationships and dynamics between termites and their environments. We found that termite communities were quite distinct, emphasising the importance of considering open ...

Unveiling Wasps as Potential Pollinators: Floral Traits and Wasp Sociality Intensify Network Centrality in a Highly Diverse Tropical Ecosystem

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1520-1531, December 2025.
ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...

Historical Fragmentation in Atlantic Forest Explains the Diversification of a Clade of Mountaintop Bromeligenous Frogs (Leptodactylidae: Crossodactylodes)

open access: yesZoologica Scripta, Volume 54, Issue 6, Page 823-839, November 2025.
ABSTRACT The Atlantic Forest domain is a biodiversity hotspot with remarkable amphibian diversity, including over 700 species, 70% of which are endemic. Most of these endemic species have restricted geographic ranges, often confined to mountainous areas, as exemplified by the leptodactylid genus Crossodactylodes.
