The initial stage of the development of the semi-free population of the Przewalski's horse in the Orenburg State Nature Reserve (Russia)

Nature Conservation Research: Заповедная наука, 2019
The Joint Directorate of the State Nature Reserves «Orenburg» and «Shaitan-Tau» (later – FSFI «Orenburg Reserves») elaborated the Programme on establishing a semi-free population of the Przewalski's horse in the Orenburg State Nature Reserve (Russia). It

Management lessons from a long‐term captive‐breeding program for a critically endangered species, Leadbeater's possum, Gymnobelideus leadbeateri

Conservation Science and Practice, Volume 6, Issue 9, September 2024.
We found that there is no difference in longevity between genetic subgroups, origin, institution, or sex in the captive Leadbeater's possum, Gymnobelideus leadbeateri. When fecundity was analyzed, the historic population had a small subset of successful males and females.

Indexes of pasturable ecology of Equus ferus przewalskii (Equidae) in steppes of the Western Manych Valley (south-east of the Rostov Region, Russia)

Nature Conservation Research: Заповедная наука, 2019
In 2015–2016, we studied the species composition, above-ground phytomass and feeding habits of semi-free Przewalski's horses (Equus ferus przewalskii) in a natural pasture of the steppe valley of the Western Manych. The above-ground mass of plants on the

Harem size should be measured by more than the sum of its parts: Phenology‐based measurements reveal joint effects of intrinsic and extrinsic factors on a polygamous herbivore under non‐stationary climatic conditions

Ecology and Evolution, Volume 14, Issue 2, February 2024.
In our study we investigate harem size phenology and related variation in a large polygamous herbivore, the Przewalski horse, using a 15‐year dataset from an introduced population in Hortobágy National Park, Hungary. Our results demonstrate that intrinsic population processes can play a major role in regulating group size and counter the effects of ...

Social Relationships of Captive Bachelor Przewalski’s Horses and Their Effect on Daily Activity and Space Use

Animals
Understanding social relationships in at-risk species held in captivity is vital for their welfare and potential reintroduction. In social species like the Przewalski’s horse (Equus ferus przewalskii), daily time allocation and space use may be ...

A Satellite-Free Centromere in Equus przewalskii Chromosome 10

, 2023
In mammals, centromeres are epigenetically specified by the histone H3 variant CENP-A and are typically associated with satellite DNA. We previously described the first example of a natural satellite-free centromere on Equus caballus chromosome 11 (ECA11)

Is leadership a reliable concept in animals? An empirical study in the horse.

PLoS ONE, 2015
Leadership is commonly invoked when accounting for the coordination of group movements in animals, yet it remains loosely defined. In parallel, there is increased evidence of the sharing of group decisions by animals on the move.
