Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

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)

Animal 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 ...

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

Journal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.

Heparin-binding proteins of seminal plasma in Nellore bulls Proteínas ligadoras à heparina do plasma seminal em touros Nelore

Ciência Rural, 2009
The aim of this study was to identify heparin-binding proteins (HBPs) in seminal plasma of Nellore (Bos taurus indicus) bulls. Bulls (n=4), 30-36 months old, 500-550kg with satisfactory seminal quality were selected.

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.

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

Ciencia 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.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
