Evolution on the edge: a model system for evolution on invasion fronts

Grant number: DP160101730 | Funding period: 2016 - 2019

Completed

Abstract

This project aims to develop a shared experimental platform, using the well-studied ecological model, Daphnia, to test emergent predictions about evolution on invasion fronts. Evolution happens rapidly on invasion fronts, accelerating the speed and potentially the damage caused by an invasion. By manipulating invasions through an experimental landscape, the project aims to answer currently infeasible questions, including whether pathogens become more virulent as they spread, and whether evolutionary trade-offs place limits on spread rate. This work would dramatically improve our understanding of biological invasions and may have implications for the management of phenomena ranging from emerg..
