Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

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

Medical and Veterinary Entomology, EarlyView.
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 ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, EarlyView.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.
