Research Summary

I am interested in the ecology and biogeochemistry of mountain lakes. In my current research, I am utilizing temperature and oxygen observations from lakes along elevational gradients to better understand how whole-lake primary productivity and respiration relate to water column stratification, light, and nutrient conditions. Results will contribute to predictions of the effects of climate and land cover changes on lake ecosystems.

Projects

Climate change induced regime shifts in Northern lake ecosystems

This project brings together new tools and concepts in biogeochemistry and ecology, with the aims of understanding and predicting the effects of climate change on the delivery of two major ecosystem services, fish production and the net greenhouse gas balance of Northern lakes.

Monitoring and management of Arctic lakes in a changing climate

The purpose of this study is to improve knowledge and monitoring of climate impacts on Arctic lakes. Specific aims include to quantify and provide threshold variables for climate change-induced regime shifts in fish resource use and production, and to develop tools and guidelines to be used in monitoring programs.

Project Video: Sound of Air Water Gas Exchange Rates

Learn, how recording the sound of streams can tell us about the gas exchange that is going on within the streams. Through gases like oxygen, we can draw conclusions about the water quality. The analysis based on sound has the potential to make water property analyses much easier.
