Evolution
Rarely have evolutionary questions been tackled using eDNA. We are aiming to change that. From research involving population genetics, gene flow, or the discovery of cryptic biodiversity, our members are interested in broadening the applications of eDNA approaches.
Hybridization
Hybridization among species is an important driver of biodiversity (generates and deteriorates species). Despite this recognition, our understanding of hybridization’s prevalence and importance is restricted because current approaches are intensive and time-consuming, hampering progress in the field. Indeed, most hybridization research still has restricted temporal and spatial resolution, limiting our ability to draw broad conclusions about evolutionary and conservation related outcomes. We aim to optimize DNA collected from the environment (eDNA) as a tool to understand the causes and consequences of hybridization between native and invasive species. The knowledge gained can be used to manage invasion dynamics and mitigate future hybridization. This work will also have the bonus of furthering the integration of eDNA approaches into broader evolutionary applications.
Current projects underway include work on Caribbean Iguanas, European Crested Newts and North American Salmonids.
