Distinguished Ecologist Seminars

We invite ecologists from around the world to speak each year. In the Fall, we highlight the work of a GDPE alum and a faculty member, and in the Spring we bring in outside speakers. We define “distinguished” broadly as someone who has contributed important work to the discipline of ecology. Below you will find information about our upcoming seminars.

For past speakers please visit our Previous Speakers page.

Nominations for speakers are due the last Tuesday in March, annually. Speakers will then be invited for the following Fall or Spring.

Fall 2022 Speakers

October 5th, 2022

“From roots to treetops: How tropical plants respond to warming and hurricane disturbance in the Tropical Responses to Altered Climate Experiment (TRACE)”

Molly Cavaleri is a forest ecophysiologist at Michigan Technological University. She has expertise in tree canopy structure and function and the cycling of carbon and water through forests. She also investigates plant thermoregulation and how temperate and tropical species acclimate to a warming world. Within the Tropical Responses to Altered Climate Experiment (TRACE), she leads the effort to explore the effects of warming and hurricane disturbance on tropical plant physiological processes like plant respiration and photosynthesis.

“Long-term recovery of aquatic ecosystems following anthropogenic disturbance: the importance of regime shifts and novel communities”


Dr. William H. Clements is a Professor in the Department of Fish, Wildlife and Conservation Biology at Colorado State University. Dr. Clements’ research interests focus primarily on community and ecosystem responses to contaminants. He is especially interested in questions that address interactions between contaminants and global climate change.  Current research in Dr. Clements’ laboratory is funded by the National Institute of Environmental Health Sciences (remediation effectiveness for mining sites); the Colorado Parks and Wildlife (quantitative assessment restoration effectiveness in the Arkansas River); the International Copper Association (the use of stream microcosms to quantify restoration effectiveness in metal-contaminated streams); and the U.G. Geological Survey (metal uptake and transfer in stream and riparian communities).
