个人简介
I study freshwater organisms in lakes and their ecological and evolutionary response to environmental change. I am interested in ways that organisms respond ecologically and evolutionarily to variable environments. Variation in time and space may result from changes in the external environment, or from the interactions among individuals and species within the community. Evolutionary, population and community responses to environmental change (whether natural or caused by humans), are in large part a function of the diversity of genotypes and species present and their differing levels of success. We’ve shown effects on predator-prey cycles, seasonal plankton dynamics, and the long-term persistence of genetic variation. My group has also shown that zooplankton make dormant eggs that can survive in lake sediments for decades or centuries and then hatch affecting population evolutionary potential. These dormant egg banks are also a resource for studying past evolutionary events since viable eggs can be hatched from different times in the past. With colleagues at the Max-Planck-Institute for Limnology (now MPI-Evolutionary Biology) we’ve used the egg bank in Lake Constance to show how Daphnia evolved resistance to toxic cyanobacteria as these primary producers increased in abundance during eutrophication. With other colleagues I am currently studying how climate change (both warming and increased storm frequency) is affecting seasonal thermal stratification and mixing patterns in lakes and how that influences plankton dynamics, especially the formation of harmful cyanobacterial blooms.
