Invasions and the Evolution of Range Limits

Show Summary Details

Preview

This chapter argues that serpentine habitats, particularly invasive plants in serpentine, are extremely useful systems for testing hypotheses about evolution and spatial spread at species range boundaries. First, it briefly outlines the broad framework shared by many theoretical models of range limits and some of the major predictions they generate. Then the chapter discusses the challenges inherent in testing these predictions on the ground. With this background in mind, it describes how past and ongoing research in serpentine has addressed some of those challenges, and sums up what this work tells us about range limits. Finally, some potential directions for new work are suggested.

Keywords: serpentine habitats; invasive plants; evolution; spatial spread
