The scientific name of the saiga is Saiga tatarica. Hyemoschus Water chevrotain H. We have gone back to old field notes from the Institute of Zoology in Kazakhstan for when a similar mass mortality occurred; reviewed research on mass deaths in other species; looked for differences in the vegetation composition between the die-off and in other years; and built statistical models to explore changes in temperature and rainfall over a range of different temporal and spatial scales.
The calves followed soon after; antelopw any given aggregation of tens of thousands of animals, it appeared that every single animal died over a period of a few days. But the next question is — why did these usually harmless bacteria become virulent? The number of animals decreased in all regions and the migratory routes shifted southward.

But the animals that do survive could be weak and susceptible to other diseases and conservationists worry that the species could now be doomed. Currently, saiga populations’ migratory routes pass five countries and different man-made constructions, such as railways, trenches, mining sites, and pipelines.

However, byconservation work by governments, scientists and NGOs was paying dividends; overall numbers had risen from its nadir of an estimated 50, in the early s to aroundin early They also need to give birth in a short time in order to coincide with the peak of lush grass before the summer heat of this harsh continental plain dries the vegetation.

Mass mortality They accompanied a research team organised by the Association for the Conservation of Biodiversity in Kazakhstanwhich also contained researchers from the Royal Veterinary College, intent on monitoring calving to learn more about saiga ecology. The calves are born large and well-developed — in fact, saigas have the largest proportional birth weight of any wild ungulate — so that they can outrun a predator within just a few days.
