Can a Top Predator Persist After One of the World's Largest Mining Dam Failures? Occupancy Dynamics of the Neotropical Otter in Brazil's Paraopeba River. [PDF]

Ecol Evol
We evaluated the effects of the 2019 Brumadinho tailings‐dam collapse on neotropical otters (Lontra longicaudis) in Brazil's Paraopeba river using multi‐season occupancy models. Six years post‐collapse, otters showed high occupancy across impacted reaches.

Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions. [PDF]

J Anim Breed Genet
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Soil Microbiome of Tropical Seasonal and Permanent Small Wetlands. [PDF]

Environ Microbiol Rep
Distinct hydrological regimes shape microbial communities and metabolic pathways in tropical wetlands. Redox‐driven shifts highlight enhanced methanogenesis under anoxia, and dominant archaeal and bacterial groups reflect specific redox conditions and adaptations, with important implications for biogeochemical cycling and climate‐relevant processes ...

First Assembly of a Draft Genome of the Critically Endangered Northern Muriqui (<i>Brachyteles hypoxanthus</i>, Primates, Atelidae) Including Non-Invasive Genotyping Strategies for the Species. [PDF]

Ecol Evol
First draft genome assembly of the critically endangered primate northern muriqui (Brachyteles hypoxanthus) and complete mitochondrial genome assembly. Set of microsatellite markers developed for the species for genotyping‐by‐sequencing using high‐throughput sequencing technology and aiming to amplify non‐invasive sampling for population genetics ...

A Hanks-type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation. [PDF]

FEBS J
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Genetic structuring and fixed polymorphisms in the gene period among natural populations of Lutzomyia longipalpis in Brazil

Parasites & Vectors, 2015
Background Even one hundred years after being originally identified, aspects of the taxonomy of the sand fly Lutzomyia longipalpis, the principal vector of Leishmania infantum in the Americas, remain unresolved for Brazilian populations of this vector ...
