Climatic and Hydrological Changes Drive Contemporary Fire Regime Transitions in the World's Largest Wetland

Global Change Biology, Volume 32, Issue 9, September 2026.
Long‐term fire data (1985–2024) and integrated modeling reveal a climate and hydrology‐driven transition toward larger fires, increased burned area, and a longer fire season, indicating the emergence of a new fire regime in the Pantanal. ABSTRACT Tropical wetlands have historically been resilient to fire, but ongoing climate and hydrological changes ...

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, Volume 109, Issue 3, Page 1856-1865, September 2026.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be
