Computational Ecology Lab

Computational Ecology is an interdisciplinary research field that aims at understanding complex ecological and evolutionary processes. The research is based on, preferably, large amounts of empirical data and relies on advanced computational methods, mathematical and statistical models with the aim to better describe and understand what characterises ecological processes. The projects in our lab are embedded in three areas: "movement ecology", "biodiversity and conservation"  and "macroevolution".

This video exemplifies some of the work the CE lab is regularly doing to relate movement to the environmental conditions. The line is a track of a migrating gull that was fitted with a GPS-Satellite tag. Remote sensing information was used to reconstruct the landuse coverage that the gull crossed on its way South, as well as a digital elevation model showing the elevation. Finally, a global wind model was used to reconstruct the wind conditions along flight. Can you see how ground speed and wind direction and wind speed are related?

Satellite remote sensing for biodiversity research and conservation applications

Issue compiled and edited by Nathalie Pettorelli, Kamran Safi, Woody Turner and Stefan Dech

The conservation of biological diversity is a major public concern. An increasingly strong link is being built between human wellbeing and biodiversity, with the weight of scientific evidence suggesting humans depend on many aspects of biodiversity, particularly the structure and functioning of ecosystems and the services that they provide.

Projects

The book

We are happy to announce that together with Chapman & Hall we have taken on the challenge to write a book called "Analysis and Mapping of Animal Movement in R". We will provide in this book the necessary information for visualisations and analysis of animal movement data in R with a direct link to the massive data base movebank.org. We will also elaborate on the contextualisation, so how we can enrich positional information using remote sensing. The aim is to provide everyone with the means to analyse movement data in a reproducible way.
