Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Pangenomic and biochemical analyses of Helcococcus ovis reveal widespread tetracycline resistance and a novel bacterial species, Helcococcus bovis

open access: yesFrontiers in Microbiology
Helcococcus ovis (H. ovis) is an opportunistic bacterial pathogen of a wide range of animal hosts including domestic ruminants, swine, avians, and humans. In this study, we sequenced the genomes of 35 Helcococcus sp.

Chronology and Demography: How Many People Lived in a Mega-Site? [PDF]

open access: yes, 2016
Since the discovery of the huge dimensions of Trypillia BIVCI mega-sites, estimations about their population size have mainly resulted magnitudes which are as extraordinary for European prehistory as the dimensions of the sites themselves.

The Ovine Brain as a Model for Human Neurodevelopment: Immunohistochemical Profiling of Brain Maturation Markers in Preterm Lambs

open access: yesJournal of Comparative Neurology, Volume 534, Issue 3, March 2026.
Prematurity negatively impacts brain development, especially at early stage of gestation. We provide a characterization and comparisons of the neurodevelopment of extreme and late preterm lamb through immunohistochemistry of targets known to be impacted by prematurity. Our results found similarity between human and lamb brain development in the context

Geometric Morphometrics of Astragalus and Shape Variation Analysis in Capra, Ovis, and Bovidae

open access: yesVeterinary Medicine and Science
In the study, it was investigated whether taxonomic differences have an effect on shape using bovine, ovis, and capra astragalus. A total of 142 samples, 32 bovine (Holstein), 71 ovis (Merino ovis), and 39 capra (Hair goat) astragalus, were used as ...

Comparison of lipopolysaccharide and outer membrane protein-lipopolysaccharide extracts in an enzyme-linked immunosorbent assay for the diagnosis of Brucella ovis infection [PDF]

open access: yes, 1986
Brucella ovis hot saline extracts and petroleum ether-chloroform-phenol lipopolysaccharide were compared in an enzyme-linked immunosorbent assay for the diagnosis of B. ovis ram epididymitis. Hot saline extracts detected greater numbers of infected rams.

Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem

open access: yesEcological Applications, Volume 36, Issue 2, March 2026.
Abstract Intensifying land use is a global threat to biodiversity, and livestock grazing—occupying 26% of terrestrial land—is one of such threats. Designated protected areas are one of the key conservation strategies to halt biodiversity loss, but their effectiveness is debated, in part because of data shortage at relevant spatial scales (>1 ha).

Variations in Seed and Fruit Traits of the Rare and Endangered Chinese Plant Lilium tsingtauense Along Environmental Gradients

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study is the first study on the response of seed traits to environmental changes in different habitats of L. tsingtauense. Different from previous studies focusing on individual growth and biomass accumulation, this study emphasizes the limiting effect of external environmental conditions, namely different geographical factors and soil environment,
