22/03/2017 - New Hope for the Saiga Antelope?

Tübingen, 3/22/2017. Senckenberg scientists have discovered that the Saiga Antelope, which is currently threatened with extinction, used to be much more flexible in its habitat and food choices in the past than previously assumed. Based on carbon and nitrogen isotopes in the collagen from the antelopes’ bones, the scientists compared the diets of fossil versus modern-day Saiga. In their study, recently published in the scientific journal “Quaternary Science Reviews,” they reached the conclusion that today’s populations are not obligatorily bound to their current habitat. This insight offers new hope for this endangered species.

During the last Ice Age, Saiga Antelopes were widespread throughout the northern hemisphere and migrated across the tundra in the company of mammoths. Today, these animals with their characteristic, trunk-like noses are only found in Central Asia and Russia. “We were interested in finding out why the Saiga’s habitat is so much more restricted today than during the period between 45,000 and 10,0000 years ago,” explains Professor Dr. Hervé Bocherens of the Senckenberg Center for Human Evolution and Palaeoenvironment (HEP) at the University of Tübingen, and he continues, “Were the animals back then better able to adapt to various environmental conditions, or is it possible that the modern antelopes are not necessarily bound to their current habitat?”

 This question, which the biogeologist from Tübingen explored together with his colleague, Dr. Dorothée Drucker, and an international team, was raised against a serious background: The Saiga Antelope is threatened with extinction. Already heavily decimated by poaching, the populations are additionally threatened by recurring virus infections. Since the beginning of this year, 2,500 animals have already died in Chowd-Aimag Province in Western Mongolia – one fourth of the entire Mongolian population. “If today’s Saiga Antelopes – like their Ice Age ancestors – were able to survive outside of semi-arid steppes, the danger of such an epidemic would not be nearly as grave,” explains Drucker.

To examine this possibility, the research team compared the composition of carbon and nitrogen isotopes in the collagen from 76 fossilized and 52 recent bones and hairs of Saiga Antelopes. Collagen is an essential organic component of the tissue in bones, teeth, cartilage, tendons, ligaments and the skin. The isotope composition in the bones’ collagen offers insights into the animals’ feeding habits.

“Contrary to what we assumed before, the diet of the Saiga during the last Ice Age was much more flexible than that of their modern-day relatives – we therefore assume that the recent Saiga Antelopes only occupy one of their potential ecological niches,” explains Bocherens and offers in conclusion, “Being able to move into other, including colder, areas would offer great opportunities for the Saiga’s protection. This should be taken into account when developing conservation programs.”

To study and understand nature with its unlimited diversity of living creatures and to preserve and manage it in a sustainable fashion as the basis of life for future generations – that has been the goal of the Senckenberg Gesellschaft für Naturforschung (Senckenberg Nature Research Society) for almost 200 years. This integrative “geobiodiversity research” and the dissemination of research and science are among Senckenberg’s primary tasks. Three nature museums in Frankfurt, Görlitz and Dresden display the diversity of life and the earth’s development over millions of years. The Senckenberg Gesellschaft für Naturforschung is a member of the Leibniz Association. The Senckenberg Nature Museum in Frankfurt is supported by the City of Frankfurt am Main as well as numerous other partners. Additional information can be found at www.senckenberg.de.

200 years of Senckenberg! 2017 marks Senckenberg’s anniversary year. For 200 years, the society, which was founded in 1817, has dedicated itself to nature research with curiosity, passion and involvement. Senckenberg will celebrate its 200-year success story with a colorful program consisting of numerous events, specially designed exhibitions and a grand museum party in the fall. Of course, the program also involves the presentation of current research and future projects. Additional information is available at: www.200jahresenckenberg.de.

The University of Tübingen is one of eleven German universities that received the recognition of excellence. Within the field of life sciences, it offers cutting-edge research in the areas of neurosciences, transnational immunology and cancer research, microbiology and infection research as well as molecular biology. Additional focal areas include geological and environmental research, archeology and anthropology, language and cognition as well as education and media. More than 28,400 students from all over the world are currently enrolled at the University of Tübingen. They can avail themselves of a wide spectrum of approximately 300 study courses – from Egyptology to Cellular Neurosciences
