An Adaptive Threshold in Mammalian Neocortical Evolution
, 2013 Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Lack of capture‐induced mortality of neonates associated with variation in handling protocols
Wildlife Society Bulletin, EarlyView.We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...

Gene Expression Profiling of Corpus luteum Reveals Important Insights about Early Pregnancy in Domestic Sheep [PDF]
, 2020 The majority of pregnancy loss in ruminants occurs during the preimplantation stage, which is thus the most critical period determining reproductive success. Here, we performed a comparative transcriptome study by sequencing total mRNA from corpus luteum

Intracranial squamous cell carcinoma in an Ovis aries.
Veterinaria italiana, 2020 Squamous cell carcinoma (SCC) is a malignant mucoepithelial tumor that affects pets and farm animals. Common sites are dorsal areas and/or areas of poor skin pigmentation exposed to mutagenic ultraviolet (UV) radiation. Novel ovine papillomavirus (OaPV3) was recently described in SCC lesions in Sardinia breed ovines.

Alzheimer's disease markers in the aged sheep (Ovis aries) [PDF]
Neurobiology of Aging, 2017 This study reports the identification and characterization of markers of Alzheimer's disease (AD) in aged sheep (Ovis aries) as a preliminary step toward making a genetically modified large animal model of AD. Importantly, the sequences of key proteins involved in AD pathogenesis are highly conserved between sheep and human.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals
Integrative 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.
