Population structure, dispersal and migration of Corncrakes (Crex crex): genetic and chemical information obtained from feathers

 

Walter Wettstein

(1971 - 2003)

We have received the sad news that Walter Wettstein, a committed member of our Corncrake Conservation Team, died in a car accident on the way from Switzerland to Hungary on 9 July 2003.

Walti studied Biology and Environmental Science and his Master's thesis, supervised by Prof. Bernhard Schmid, was about the conservation of insect diversity in sub-alpine mires. A few years ago, Walti moved to Hungary where he married in March 2000. For years, he worked in Eastern Hungary, learned the Hungarian language and gathered a comprehensive knowledge about nature conservation in the country. He was co-founder of "Pro Theiss" and a director of this organisation.

He developed the basis for long-term Corncrake monitoring in Hungary and his fieldwork on this species led to the designation of the second largest 'Important Bird Area' (IBA) in Hungary.

His PhD thesis was just being finalised. Walti was only 32 years old.

Our thoughts are with his wife Andrea, young daughter Liza, all his relatives and friends.

Abstract:
In 2001, the Corncrake Conservation Team started a population genetic research project about the Corncrake together with the University of Zurich, Switzerland. It is the aim to get better understanding of the population structure and the dispersal patterns over its whole breeding range. This will provide important information to select the most effective conservation strategies and to co-ordinate them in a biologically sensible way. The needed molecular-biological tools (microsatellites) have been developed at the University of Zurich, and now, already the feathers of the Corncrakes provide enough DNS to carry out the needed measures. To make interesting conclusions, it would be important to obtain feathers from a geographic range as broad as possible. A minimum of 20-30 feathers are needed from every region/country to make sensible statistical tests. Now, we want to ask all persons, who will catch or ring Corncrakes in 2001 or 2002 to participate in our project and collect the needed feathers for us. It will only be a minor additional effort, but of essential importance for this research!
