That tangled web Human practices are deforming frogs Sept. 7, 2004 -- Copyright Pieter Johnson 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.

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.
