Time budget-, behavioral synchrony- and body score development of a newly released Przewalski's horse group Equus ferus przewalskii, in the Great Gobi B Strictly Protected Area in SW Mongolia. [PDF]

Appl Anim Behav Sci, 2007
The Przewalski’s horse (Equus ferus przewalskii) became extinct in the wild in the 1960s, but survived as a species due to captive breeding. There have been several initiatives to re-introduce the species in central Asia, but until now only two projects ...

Joyful by nature: approaches to investigate the evolution and function of joy in non‐human animals

Biological Reviews, Volume 98, Issue 5, Page 1548-1563, October 2023., 2023
ABSTRACT The nature and evolution of positive emotion is a major question remaining unanswered in science and philosophy. The study of feelings and emotions in humans and animals is dominated by discussion of affective states that have negative valence.

Collective decision‐making in aquatic mammals

Mammal Review, Volume 53, Issue 4, Page 238-253, October 2023., 2023
A framework for determining how decisions on a group level are made by non‐human mammals. These decisions can either be shared (requiring a threshold/majority in a ‘consensus’ decision or an individual choice regarding which option to follow in a ‘combined’ decision) or unshared (where individuals will either follow a single leader in an ‘unshared ...

Losing the forest for the tree? On the wisdom of subpopulation management

Zoo Biology, Volume 42, Issue 5, Page 591-604, September/October 2023., 2023
Disagreement over species, subspecies, and ESU definitions and poor support for many population designations interacts with concerns over hybridization and outbreeding depression to promote subpopulation management. Conversely, managing populations as gene pools rather than taxonomic units allows for larger population sizes and reduced extinction risk.

Gaps in mammal conservation in China: An analysis with a framework based on minimum area requirements

Global Change Biology, Volume 29, Issue 18, Page 5224-5239, September 2023., 2023
Climate change, habitat loss, and human disturbance are endangering biodiversity. Protecting habitats requires a global effort to establish effective protected areas and halt biodiversity decline. In China, conservation management is often carried out based on administrative divisions.

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.

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.

Acute phase reactants in nondomesticated mammals—A veterinary clinical pathology perspective

Veterinary Clinical Pathology, Volume 52, Issue S1, Page 19-36, February 2023., 2023
Abstract Applications for acute phase reactants (APRs) in nondomesticated mammals include identifying inflammatory disease, monitoring the course of specific disease processes and recovery during rehabilitation, detecting preclinical or subclinical disease, being used as bioindicators for monitoring population and ecosystem health, and as markers of ...

The putative maintaining mechanism of gut bacterial ecosystem in giant pandas and its potential application in conservation

Evolutionary Applications, Volume 16, Issue 1, Page 36-47, January 2023., 2023
Abstract Animals living in captivity and the wild show differences in the internal structure of their gut microbiomes. Here, we performed a meta‐analysis of the microbial data of about 494 fecal samples obtained from giant pandas (captive and wild giant pandas).

Epigenetic Variability of the Highly Endangered Przewalski’s Horses in Temporal and Geographical Populations

Mongolian Journal of Biological Sciences, 2020
Despite the successful conservation of the Przewalski’s horse (PH), Equus ferus przewalskii Groves, 1986 in captivity and reintroduction attempts in Mongolia, there is little knowledge on the genetic variability of these populations.
