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 a model field system over the last few years. These small floating aquatic plants reproduce incredibly quickly and are being studied as a biofuel and a bio-remediation agent. The Turcotte lab will use these plants to explore numerous questions relating to 1) Eco-Evolutionary Dynamics of Species Coexistence, and 2) Evolutionary Rescue in Communities, among many others. 

Drosophila Seasonal Dynamics

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

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.
