Long‐Term Changes in Planktonic Ciliate Beta Diversity Under Contrasting Hydrological Regulation in A River–Floodplain System

open access: yesEnvironmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrological regulation by dams reshaped ciliate biodiversity over 14 years, increasing temporal compositional change and ecological uniqueness while accelerating declines in richness and density. These results highlight flood‐pulse dynamics as a fundamental mechanism sustaining biodiversity and ecological integrity in river‐floodplain ecosystems ...

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1771-1785, September 2026.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 551-559, September 2026.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...
