Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic
Ecological Research, Volume 41, Issue 5, September 2026.This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Austral Entomology, Volume 65, Issue 3, August 2026.ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from ...
