Respiratory Complex I in Bos taurus and Paracoccus denitrificans Pumps Four Protons across the Membrane for Every NADH Oxidized*

Journal of Biological Chemistry, 2017
Respiratory complex I couples electron transfer between NADH and ubiquinone to proton translocation across an energy-transducing membrane to support the proton-motive force that drives ATP synthesis.

Are human‐altered landscapes reshaping carnivore niche spaces in the Trans‐Himalaya?

Wildlife Biology, EarlyView.
Understanding carnivore interactions under growing human pressures is crucial for conservation. We examined spatial and temporal niche structuring among snow leopards Panthera uncia, Himalayan wolves Canis lupus chanco, and red foxes Vulpes vulpes; while also incorporating free‐ranging dogs Canis lupus familiaris as a human‐subsidized mesopredator ...

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains

Wildlife Biology, EarlyView.
Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population

Genetics and Molecular Biology, 2005
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2

Genome-wide association studies for tick resistance in Bos taurus × Bos indicus crossbred cattle: A deeper look into this intricate mechanism.

Journal of Dairy Science, 2018
Rhipicephalus (Boophilus) microplus is the main cattle ectoparasite in tropical areas. Gir × Holstein crossbred cows are well adapted to different production systems in Brazil.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Genetic group and heterosis on morphometric measurements during the growth of male beef cattle

Semina: Ciências Agrárias, 2016
In the present study, the effects of genetic group and heterosis on body measurements of purebreds (Charolais - C and Nellore - N), first-generation crossbreds (G1) (1/2C1/2N and 1/2N1/2C), and second-generation crossbreds (G2) (3/4C1/4N and 3/4N1/4C ...
