Experimental Eco-Evolutionary Dynamics 

Eco-Evolutionary Dynamics using Duckweed

In order to experimentally test hypotheses related to Evolutionary Community Ecology, Simon Hart and I have developed Duckweed as model field system over the last few years. This small floating aquatic plants reproduce incredibly quickly and is being studied as a biofuel and a bio-remediation agent. The Turcotte lab will use these group of species to explore numerous questions relating to 1) Rapid Evolution of Coexistence Mechanisms and 2) Evolutionary Rescue in Communities among many others.

Drosophila Eco-Evolutionary seasonal dynamics

In collaboration with Paul Schmidt at UPenn we are experimentally testing the eco-evolutionary impacts of rapid seasonal adaptation in Drosophila melanogaster. 

Aphids population dynamics     

Previous research manipulated rapid evolution by altering the genetic composition of aphid populations in the field leading to strong impacts on concurrent population dynamics.
