Species Identification of Ancient and Medieval Representatives of the Genus Equus based on Genetic Data

open access: yesАрхеология евразийских степей
Since one of the peculiarities of the evolutionary history of representatives of the genus Equus (horses, asses and zebras) is the high similarity of the morphology of the skeletons of different species of this genus, morphometric characteristics do not ...

The Equus Datum and the Early Radiation of Equus in China

open access: yesFrontiers in Ecology and Evolution, 2019
To approach a comprehensive understanding of the Equus Datum, we summarize the history of the study of Chinese fossil equids, from the “dragon bones” stage to scientific investigation, by Chinese, European and American people, and then review the ...

A Mutual Information Based Sequence Distance For Vertebrate Phylogeny Using Complete Mitochondrial Genomes [PDF]

open access: yes, 2007
Traditional sequence distances require alignment. A new mutual information based sequence distance without alignment is defined in this paper. This distance is based on compositional vectors of DNA sequences or protein sequences from complete genomes ...

DNA Methylation of Igf2r Promoter CpG Island 2 Governs Cis-Acting Inheritance and Gene Dosage in Equine Hybrids

open access: yesBiology
Genomic imprinting is critical for mammalian development, but its regulation varies across species. The insulin-like growth factor 2 receptor (IGF2R), which is a maternally expressed imprinted gene critical for cell proliferation and differentiation, as ...

Detomidine and butorphanol for standing sedation in a range of zoo-kept ungulate species [PDF]

open access: yes, 2017
General anesthesia poses risks for larger zoo species, like cardiorespiratory depression, myopathy, and hyperthermia. In ruminants, ruminal bloat and regurgitation of rumen contents with potential aspiration pneumonia are added risks.
