FE : Cynthia Chang talks with Alan Knapp on Competition between genotypes of a dominant grass

Cynthia Chang talks with Alan Knapp on her paper: Chang, C. C., Smith, M. D. (2014), Resource availability modulates above- and below-ground competitive interactions between genotypes of a dominant C4 grass. Functional Ecology. doi: 10.1111/1365-2435.12227 Plants compete for essential resources like light, water, and nitrogen, and understanding how plants coexist when these resources are limiting helps explain how they persist in a changing environment. Dominant species (the most abundant species in a community) are ecologically important because they contribute a disproportionate amount to ecosystem functions like productivity, invasion resistance, and resilience to climate change, so it is particularly important to understand how individuals within a dominant species coexist when resources are limiting. In this podcast Cynthia Chang and Alan Knapp look at why naturally co-occurring genotypes coexist, providing insight into how genetic diversity within dominant plant species is maintained and how this can affect important ecosystem processes http://onlinelibrary.wiley.com/doi/10.1111/1365-2435.12227/abstract
