Source-sink
dynamics exist within landscapes where at least two sorts of habitats are present.
There is one or more favourable 'source' habitat where birth rates exceed death
rates and one or more 'sink' habitat where death rates exceed birth rates.
Sink habitats are inhabited because individuals in source habitats control access to resources and force less dominant individuals into these sink habitats.
