Brent geese in a meta-ecosystem
The ecology of migratory species at different scales Wimke Crets-Fokkema
1. Detailed understanding of the ecology of migratory species at different
spatial scales is necessary to effectively conserve seasonal migrants and the meta-ecosystems in which those species are key connectors
(chapter 1).
2. Ontogenetic niche shifts should not be overlooked as an important
explanatory factor for population dynamics and the ecology of species (de Roos & Persson 2013; chapter 2)
3. The wealth of data obtained in current studies, that are set up to
track the movements and habitat use of species, poses new challenges, including finding new methods to describe and statistically test general patterns (Nathan 2008; Rutz & Hays 2009; chapter 3).
4. Networks have broad applications within ecology: not only can the
techniques be used to map the ecological interactions of species with their biotic and abiotic environment (Olff et al. 2009; Fontaine et al. 2011), network techniques are also highly suitable to study the movements and habitat use of individuals at different spatial scales (chapter 3 and 4).
5. The use of urban or agricultural landscapes influences the ecology,
including habitat use and movement patterns, of animals in general and brent geese in particular (Rouleau et al 2002; Fahrig 2007; chapter 4)
6. Interactions between species and their food resources can be determined
by the conditions under which the food resources are occurring: adaptations of food resources to extreme environmental conditions can cause a higher preference for these particular food resources (chapter 5).
7) Brent geese have a sweet tooth (chapter 5).
