We present a survey of metapopulation terminology and outline the kinds of studies that have been conducted on single-species and multispecies metapopulations. Science , — Second, the interruption of movement between areas of the river may prevent both the rescue of populations that may go locally extinct Hanski, and the movement of genes that might be beneficial in scenarios of environmental change Tallmon et al.

To answer this question we tested for changes in dispersal data collection and use over time. The scientific literature produced by Hanski is rather enormous; the ISI Web of Knowledge database suggests that he is the author or co-author of more than scientific articles and has edited several books. Some demographic and environmental consequences of environmental heterogeneity for biological control. All Subjects All Subjects.
