Plant conservation genetics and applied molecular ecology

Humans continue to modify landscapes at an alarming rate. Major consequences of this are the fragmentation of habitats into islands within highly complex matrices. In the temperate regions this has been a gradual process, but in the tropics this is happening at unprecedented rates. For plant species, and especially tropical trees the consequence of fragmentation can be highly variable and depend on their reproductive ecology, their mutualism and their mating system. Understanding how these factors interact to influence a species vulnerability to disturbance is essential to management of resilient landscapes. My research aims to advance our understanding of how habitat degradation, especially fragmentation impacts on plant biodiversity. I divide my research into three core areas, plant reproduction and the genetic consequences of habitat fragmentation, trees species coexistence in tropical forest and tropical forest restoration. Across all of these themes I apply a combination of molecular and traditional ecological approaches to address fundamental research questions, applicable to the sustainable management of natural systems.
