Frecuencias alélicas para variantes SNP en el gen Nramp1 en bovinos infectados con Brucella abortus o clasificados por resistencia al patógeno

open access: yesCiencia y Tecnología Agropecuaria, 2009
La resistencia natural a la brucelosis en bovinos ha sido asociada a factores genéticos, principalmente a algunos polimorfismos de nucleótido simple ubicados dentro del gen Nramp1.

Lures do not increase box‐trapping success of an endangered felid in South Texas

open access: yesWildlife Society Bulletin, EarlyView.
We used a randomized design and linear regression to assess whether visual (compact disc [CD] and ribbon), and olfactory (musk and ocelot urine) lures would increase capture success of three mesocarnivores (ocelots [Leopardus pardalis], bobcats [Lynx rufus], and coyotes [Canis latrans]) with box traps baited with a live bird from December 2023 to April

Seed dormancy explains plant response to mass mortality events

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mass mortality events (MMEs) are large‐scale, rapid die‐offs resulting in extreme inputs of carrion biomass. Recent work demonstrates the effects of increasing carrion biomass on plant communities modulated by vertebrate scavengers and herbivores.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal 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.

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

open access: yesInsect 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.

Candidate SNP of CACNA2D1 Gene Associated with Clinical Mastitis and Production Traits in Sahiwal (Bos taurus indicus) and Karan Fries (Bos taurus taurus × Bos taurus indicus)

open access: yesAnimal Biotechnology, 2018
The present study was conducted to identify polymorphisms in CACNA2D1 gene and their association with clinical mastitis and production traits. Exon 18 and its flanking regions were screened for the presence of SNPs. Statistical analysis was performed to identify association of period of birth, breed, and genotype with mastitis incidence on randomly ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations

open access: yesGenetics and Molecular Biology, 2005
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in ...
