Equus ferus przewalskii pre- and post-reintroduction
Focal animal sampling was used to determine the 24-h time budget of a takh harem stallion Ž . Equus ferus przewalskii during the 2 weeks prior to, and the two weeks following, reintroduction into the Hustain Nuruu Steppe Reserve, Mongolia. Both before and after release, the stallion spent approximately 47% of his time grazing, 6% standing, and 5% in recumbent rest. The biggest changes to the ti...
متن کاملFixed nucleotide differences on the Y chromosome indicate clear divergence between Equus przewalskii and Equus caballus.
The phylogenetic relationship between Equus przewalskii and E. caballus is often a matter of debate. Although these taxa have different chromosome numbers, they do not form monophyletic clades in a phylogenetic tree based on mtDNA sequences. Here we report sequence variation from five newly identified Y chromosome regions of the horse. Two fixed nucleotide differences on the Y chromosome clearl...
متن کاملOcclusal Enamel Complexity in Middle Miocene to Holocene Equids (Equidae: Perissodactyla) of North America
Four groups of equids, "Anchitheriinae," Merychippine-grade Equinae, Hipparionini, and Equini, coexisted in the middle Miocene, but only the Equini remains after 16 Myr of evolution and extinction. Each group is distinct in its occlusal enamel pattern. These patterns have been compared qualitatively but rarely quantitatively. The processes influencing the evolution of these occlusal patterns ha...
متن کاملHorses in the Cloud: big data exploration and mining of fossil and extant Equus (Mammalia: Equidae)
—Extant species of the genus Equus (e.g., horses, asses, and zebras) have a widespread distribution today on all continents except Antarctica. Extinct species of Equus represented by fossils were likewise widely distributed in the Pliocene and even more so during the Pleistocene. In order to understand the efficacy of “big data” for (paleo)biogeographic analyses, location records (latitude, lon...
متن کاملSocial and spatial structure and range use by Kaimanawa wild horses (Equus caballus: Equidae)
We measured horse density, social structure, habitat use, home ranges and altitudinal micro-climates in the south-western Kaimanawa ranges east of Waiouru, New Zealand. Horse density in the Auahitotara ecological sector averaged 3.6 horses.km and ranged from 0.9 to 5.2 horses.km within different zones. The population’s social structure was like that of other feral horse populations with an even...
