Mitochondrial DNA variation and population structure of the Critically Endangered saiga antelope Saiga tatarica [PDF]

Oryx, 2006
We analysed the mtDNA control region (HV1) of 93 tissue samples from all five populations of the saiga antelope Saiga tatarica. The results show a slight but clear distinction between S. t. mongolica and S. t. tatarica, supporting the current designation of S. t. mongolica as a subspecies rather than a separate species. Levels of genetic diversity were

Rewilding through inappropriate species introduction: The case of European bison in Spain

Conservation Science and Practice, Volume 6, Issue 12, December 2024.
The increasing pressure to release bisons as a wild species in Spain, as an ecological analogue of the extinct steppe bison Bison priscus, makes it an excellent example to reflect on whether the rewilding of Europe would be, or not, biogeographically advisable. We scrutiny this proposal taking into account the best available evidence on the species, in

Risks to the Growth, Conservation and Management of the Ural Saiga Population

Diversity
The Ural saiga antelope (Saiga tatarica) inhabits the expansive steppes and deserts of Kazakhstan. Disease outbreaks, particularly among livestock, can impact saiga populations by causing competition for resources and increasing mortality rates.

Disassembled Food Webs and Messy Projections: Modern Ungulate Communities in the Face of Unabating Human Population Growth

Frontiers in Ecology and Evolution, 2020
The human population grows inexorably. When Charles Darwin explored the southern cone of South America in 1830, fewer than 1.2 billion people inhabited Earth. When Ehrlich’s Population Bomb appeared in 1968, there were ∼3.5 billion people.
