Assistant Professor of Biology

Expertise: biology, ecology, ecosystem, natural history, evolution, biodiversity, food webs, theory

Bio:

Chase
Jonathan M. Chase, assistant professor of biology, focuses his research on the rules (or lack thereof) underlying the diversity, distribution, and abundance of animal and plant species from the population/community/ecosystem perspective. His research combines observational, theoretical, and experimental approaches to improve understanding of these rules.

That tangled web

Human practices are deforming frogs

Sept. 7, 2004 --
Eutrophication is caused by higher phosphorous and nitrogen that create a profound impact on the food web, threatening the frogs' existence.

Eutrophication is caused by higher phosphorous and nitrogen that create a profound impact on the food web, threatening the frogs' existence.
A collaboration involving ecologists at WUSTL and the University of Wisconsin strongly points to farming practices and development, two factors that create a condition called eutrophication in ponds and wetlands, as factors behind the high incidence of deformed frogs. Eutrophication is caused by higher phosphorus and nitrogen (prime components of agricultural fertilizer) levels in wet ecosystems. Higher levels of these nutrients cause a profound impact on the food web that imperils the frogs' existence.

Drought Can Destroy Diversity
LiveScience.com

Oct. 22, 2007 -- Scientists are more interested than ever in the effects of extreme climate swings, such as prolonged drought, because the computer models predict wilder extremes as one effect of the climate change now underway.
WUSTL biology professor and ecologist Jonathan Chase comments on his study that appeared in the Oct. 15 issue of the journal Proceedings of the National Academy of Sciences.


Invasive Mosquito Species Found in Midwest
Washington Post, St. Louis Post-Dispatch and 32 others

Sept. 27, 2005 -- A species of mosquito common in the eastern U.S. and capable of carrying the West Nile virus has made its way to the Midwest for the first time, a finding made by WUSTL junior chemistry major Stephanie Gallitano.
Gallitano, WUSTL biology professor Jonathan Chase and Gallitano's mentor and postdoctoral fellow James Vonesh comment.



Additional Background: Jonathan M. Chase,, Ph.D., is associate professor of biology in Arts & Sciences and director of WUSTL's Tyson Research Center. His research posits the question: Do rules govern ecology, or are we simply natural historians gathering special cases? Chase's research interests are broad but generally focus on the rules (or lack thereof) underlying the diversity, distribution, and abundance of animal and plant species from the population/community/ecosystem perspective. He is particularly interested in the patterns and processes that develop at the interface between local and regional spatial scales. To approach these questions, he combines mathematical theory, observations and statistical approaches, rigorous experimentation in both the field and lab, and a knowledge of natural history.

Chase has the bachelor's degree from the University of Michigan, a master's from Utah State University and the Ph.D. fromm the University of Chicago, all in biology. He has autored many important papers, and in 2003 published, with co-author M.A. Leibold, Ecological Niches: LinkingClassical and Contemporary Approaches, University of Chicago Press.

As director of the Tyson Research Center, he coordinates research projects with university and area researchers and oversees activities at the 2,000-acre field site. Tyson Research Center, just 25 minutes from the Danforth Campus on I-44 at Beaumont and Antire Road, was conveyed to the University in 1963 by the U.S. government following a variety of uses, including munitions storage during World War II and the Korean conflict. The site has more than 80 buildings and installations erected by the government. Before 1941, the land primarily was used for crops and grazing as well as woodlands.
