Recent Advances and Current Challenges in Applying Source-Sink Theory to Species Conservation

The source-sink paradigm has been a powerful tool for focusing theoretical and empirical explorations of population dynamics in heterogeneous landscapes. The prevalence of suspected source-sink dynamics in empirical studies would lead to the conclusion that sources and sinks are common. However, important questions remain about how source-sink dynamics have been assessed in past studies and the degree to which current approaches apply to...
