Cloning in action: can embryo splitting, induced pluripotency and somatic cell nuclear transfer contribute to endangered species conservation?

Biological Reviews, Volume 98, Issue 4, Page 1225-1249, August 2023., 2023
ABSTRACT The term ‘cloning’ refers to the production of genetically identical individuals but has meant different things throughout the history of science: a natural means of reproduction in bacteria, a routine procedure in horticulture, and an ever‐evolving gamut of molecular technologies in vertebrates.

Sympatry Increases Predation Risk for an Endangered Ungulate. [PDF]

Ecol Evol
We characterized predation risk for Peninsular bighorn sheep and southern mule deer across their ranges to understand how topography, habitat, forage, and prey habitat suitability affect where pumas are likely to predate both species. The presence of the second ungulate species increased predation risk for both species but had the greatest effect on ...

Out of the stable: Social disruption and concurrent shifts in the feral mare (Equus caballus) fecal microbiota

Ecology and Evolution, Volume 13, Issue 5, May 2023., 2023
We investigated the effects of increased social instability, as determined by the number of group changes made by females, on the microbiota in free‐living, feral horses (Equus caballus) on Shackleford Banks, a barrier island off the North Carolina coast.

A Primitive Trait in Two Breeds of Equus Caballus Revealed by Comparative Anatomy of the Distal Limb

Animals, 2019
The 55-million-year history of equine phylogeny has been well-documented from the skeletal record; however, this is less true for the soft tissue structures that are now vestigial in modern horse.

Influence of weather on the behaviour of reintroduced Przewalski’s horses in the Great Gobi B Strictly Protected Area (Mongolia): implications for conservation

BMC Zoology, 2022
Background Reintroduction is a common technique for re-establishing threatened species. However, the adaptation to novel habitats with distinct conditions poses a risk of failure.

Dynamics of intestinal parasite infection in Przewalski's horses reintroduced to Pre-Urals Steppe, Orenburg State Nature Reserve (Russia)

Nature Conservation Research: Заповедная наука, 2019
The first successful reintroduction programme for the Przewalski's horse in Russia was launched by FSFI «Orenburg Reserves» in 2015. A total of 36 Przewalski's horses were brought to the Pre-Urals Steppe site from semi-reserves in France and Hungary in ...

Improved sperm cryosurvival in diluents containing amides versus glycerol in the Przewalski’s horse (Equus ferus przewalskii) [PDF]

Cryobiology, 2014
Two studies were conducted to understand sperm cryosensitivity in an endangered equid, the Przewalski's horse (Equus ferus przewalski), while testing the cryoprotectant ability of formamides. The first assessed the toxicity of permeating cryoprotectants (glycerol, methylformamide [MF] and dimethylformamide [DMF]) to Przewalski's horse spermatozoa ...

Gasterophilus (Diptera, Gasterophilidae) infestation of equids in the Kalamaili Nature Reserve, China

Parasite, 2016
We investigated infections with Gasterophilus spp. in three equids within the Kalamaili Nature Reserve (northern China). We conducted necropsies on 6 Przewalski’s horses (Equus ferus przewalskii) and 6 Mongolian wild asses (Equus hemionus) and ...
