We study evolutionary and ecological processes mediated by parasitism in aquatic ecosystems in a changing world. Parasites are ubiquitous and impose strong selection on their hosts to evolve resistance, while themselves being under strong selection to overcome host defenses. We aim to improve understanding of the interface between host–parasite coevolution and major ecological processes under the influence of global environmental change, such as elevated temperatures and the presence of anthropogenic pollutants (e.g., nanoplastics, pesticides). We focus on how global change (a) impacts hosts, parasite diversity, and the occurrence of infectious diseases, and (b) shapes interactions between hosts, parasites, and non-host species.

We use both field and lab studies to address questions of disease in aquatic ecosystems using different model organisms. Through field studies of natural populations, we explore the links between environmental factors and the occurrence of disease. Our field sites, consisting of sets of large permanent lakes or small ponds, represent a gradient of environmental conditions. In the lab, we conduct experiments ranging from single-generation studies to longer-term evolution experiments. We focus on diseases of plankton organisms that occupy multiple trophic levels in aquatic food webs. Specifically, we study the impacts of anthropogenic stressors on interactions between zooplankton Daphnia and their common parasites, as well as phytoplankton cyanobacteria and their parasitic chytrids. To capture changes induced by environmental stressors, we examine both phenotypic traits and genotypic changes. Our ultimate goal is to predict how these interactions, along with their associated ecological and evolutionary processes, may shift under future environmental scenarios.

Congratulations and Welcome Dr. Le Lie :partying_face:!!!!!

May 12, 2025

Farewell to Dr. Amruta Rajajaran!!!

 

Dr. Le Liu has been awarded a 2-year postdoc fellowship from DAAD-CSC to join our group! Le will work on the IMPACT project starting this Fall. Le will focus on how different concentrations of nanoplastic impact Daphnia communities and their disease dynamics. 

 

 

 

 

 

 

We celebrated Amrutas time in the lab and accomplishments with some good food and a fancy Daphnia cake.
