Food web models in politics and management

Use of coastal and estuarine food web models in politics and management: The need for an entire ecosystem approach to prevent crises

ENA Wirkshop 2017 - Participants (Photo: Alfred-Wegener-Institut)

Aim of the workshop

The course aims to increase the understanding of food web model indicators. We will discuss and share ideas how to improve food web modeling and how to apply its various results to integrated ecosystem-based management.

Date

25^th Sept. 2017 – 27^th Sept. 2017

Registration

Registration is CLOSED

Please contact Dr. Ulrike Schückel or Dr. Sabine Horn to sign up for the workshop.

Location

Wadden Sea Station on Sylt of the Alfred- Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.

Costs

The course is on a volunteer basis and has no further expenses out of accommodation and travel.

Accomodation

Sylt is a popular holiday island and September is still an attractive month for tourists to come here. We therefore recommend booking an accommodation as soon as possible.
Students are welcome to stay in our guesthouse “Möbius”. For more information please contact Annabell Mitzel.

Further possibilities for accommodation close to the institute could be found here.
