Welcome to the Dechmann Lab!

          Resource Fluctuations and Animal Movement

Resources fluctuate in their availability daily, seasonally and sometimes unpredictably. We are interested in the strategies animals have developed to deal with resource fluctuations, especially long and short distance movement, and how this can be optimized by social information transfer and alternative strategies in animals that cannot follow resources in space.

See below for project overviews.

We completed our first bat box checks in Bischofszell and Frauenfeld last week and found many noctules preparing to migrate, 47 bats in one box alone!

First noctules of the year!

Project Overviews

<p>Eidolon may (still) be the most numerous mammal of Africa and yet what we know about this bat barely scratches the surface. We study the unique long-distance migration of this species in one of the ICARUS pilot projects. We aim to understand how this massive movement across the African continent is driven by environmental factors, but facilitated by exploding information networks of gigantic colonies informing individual decisions. By feeding our data and conclusions into studies about the spread of diseases of human concern, this will also contribute to understanding the actual role fruit bats play in this urgent topic.</p>

How are these foraging challenges overcome through information transfer by different modalities? And finally how is this linked to the metabolism and physiology of the bats?</p>

Optimizing foraging through information transfer in bats feeding on ephemeral resources

We study bats that are highly specialized on ephemeral resources. How does the availability of resources in time and space affect foraging efficiency? How are these foraging challenges overcome through information transfer by different modalities? And finally how is this linked to the metabolism and physiology of the bats?
