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

open access: yesJournal 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).

Plastid genome structure and phylogenomics of the freshwater red algal order Batrachospermales (Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract For the freshwater red algal order Batrachospermales, the number of plastid genomes available is relatively small compared to the number of genera. Fully assembled plastid genomes can provide insights into plastid evolution and crucial data for phylogenetic reconstruction.

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, 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 ...

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, EarlyView.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Coronavirus Detection in Bats Captured on the Deforestation Arc of Mato Grosso, Brazil

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Coronaviruses (CoV) are RNA viruses associated with enteric and respiratory diseases and known for their emergence potential in humans and other mammals. CoVs originate from zoonotic transmission, in which bats are natural reservoirs. Previous studies suggest that CoV diversity is positively correlated with bat diversity, whereas anthropogenic
