Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

The Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Co‐Infection of Brucella canis and Brucella melitensis in a Domestic Dog With Zoonotic Transmission to Human, China

Animal Research and One Health, EarlyView.
Source attribution figure for human and dogs Brucella canis infections. ABSTRACT We report a rare occurrence of genetic material from both Brucella canis and B. melitensis detected in a domesticated dog from Jiangsu Province, China. The detection was confirmed through serological assays, quantitative PCR (qPCR), metagenomic and genomic sequencing ...

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.
