Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Otophysan fishes represent 70% of living freshwater fishes with 12,000 species. Relationships among their four orders were explored through a dense taxonomic sampling including 529 complete mitochondrial genomes and 4 nuclear genes for 324 species.

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling
