Research

Wildlife research is focused on basic research, applied research and monitoring. ITAW's goal is to elucidate the biology and ecology of wild animals as well as to investigate the influence of anthropogenic activities on wildlife. Health status and populations are assessed. Research is concentrated on:

 

1) Investigations on Health Status



Clinical and morphological pathology of different wild animals

Auditory research: audiometric measurements, CT, impairment and morphology of hearing

Infectious diseases / zoonoses: effects of parasitic, bacterial and viral infections (in particular, distemper infection in seals), fomites, resistencies

Endocrine, immune, reproductive, respiratory and digestive systems, nutritional status

Effects of chemical and acoustic pollution of the environment Determination of good environmental status (natural influences vs. anthropogenic influences) Epidemiology

2) Investigations on Habitat Use

 

Population surveys of marine and terrestrial mammals primarily through aerial and ship-based surveys, spotlight surveys, photo traps, infrared cameras, etc.

Feeding ecology (stomach contents, fatty acid analyses, analysis of stable isotopes, stool samples, telemetry, survey of food availability)

4) Re-establishment, Return, Re-introduction of Wild Animals

 

Re-establishment of extinct wild animal species (e.g., wisent, lynx)

5) Databases and Sample Repositories 

     

 

The vast majority of these research efforts are financed through third-party funding obtained from state and federal ministries, the European Union and numerous foundations, as well as through funding of the Association of Supporters (Förderverein). Research contracts are assigned to the Institute by the Ministry of Nutrition, Agriculture, Consumer Protection and Rural Development of the State of Lower Saxony, the Federal Foundation for the Environment (Deutsche Bundesstiftung Umwelt, DBU), the Nature+Human Foundation (Stiftung Natur+Mensch) and the Hunting Association of Lower Saxony (Landesjägerschaft Niedersachsen e.V.). Scientific cooperations exist with numerous research institutions (links) in Germany and beyond. Scientists of ITAW serve on several international bodies (e.g., TSEG, ASCOBANS, ICES, IWC, IAPEME) and advise the German federal government on the implementation of treaties. (particularly: distemper infections in seals)

Current research projects of the Institute for Terrestrial and Aquatic Wildlife Reserach (ITAW) are described here: terrestrial research and aquatic research
