How genetic connectivity networks mediate colonization dynamics in chronic fragmented populations: an integrated spatio-temporal approach

How genetic connectivity networks mediate colonization dynamics in chronic fragmented populations: an integrated spatio-temporal approach

The consequences of habitat fragmentation are a major theme in plant ecology and conservation biology. We know that demographic and genetic population features are affected by fragmentation that in turn determine the success of subsequent recolonization. Yet, we lack an integrated understanding of how these factors interact.

Here we propose an integrated study of the genetic and demographic outcomes of anthropogenic fragmentation and subsequent re-colonization, using a top-level species of the Mediterranean costal dune ecosystem, the Juniperus phoeniceae turbinata. This research has important theoretical and applied outcomes. Theoretically, it links for the first time fragmentation background and historical genetic connectivity with current colonization dynamics. Pragmatically, it establishes a foundation for realistic prediction and management of forest recovery, in and beyond this vulnerable coastal dune ecosystem.
