Widespread Detection of Amphibian Pathogens in Frog‐Biting Midges (Corethrellidae): Implications for Xenosurveillance

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Amphibian populations worldwide face threats from emerging infectious diseases. We screened frog‐biting midges (Corethrella spp.) from Central and South America for Batrachochytrium dendrobatidis, Ranaviruses, and Trypanosoma spp. using qPCR. All three pathogens were detected, indicating that Corethrella may act as vectors and represent promising tools

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 220-231, March 2026.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...
