Food Web Analysis - From Sample to Model - 2016 edition
Aim of the course
Introduction into food web analysis using the example of the Wadden Sea Ecosystem. Demonstration of the necessary steps of food web description: sampling and habitat analysis as well as basics of the ecological network analysis will be communicated by explaining and exercising simple modelling.
Wadden Sea Station on Sylt of the Alfred- Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung
Advanced students, Bachelor,-Master- and PhD students with ecologically focused programme of study. Although the course is focusing on a marine ecosystem, interested students of terrestrial and limnic ecology as well as advanced disciplines are welcome.
For registration or further information please contact directly Dr. Harald Asmus.
Unfortunately we have limited space and therefore who will register first will get a place.
The course is on volunteer basis and has no further expenses out of accommodation and meals.
There is one supermarket close to the village and a couple of bakeries where you may buy all what you need. Furthermore the guest house has a fully equipped kitchen with living room where you may prepare your meals.
We ask you to bring your laptop and to install the required software beforehand. This lets speed up the preparation for excises and practices with the computer. Further material and information will be given in due time.
