Global warming could cause insect population explosion mongabay.com October 30, 2006 Scientists from the University of Washington found that insect species found in warmer environments have faster population growth rates as temperatures increase. This growth may well have significant impacts on agriculture, public health, conservation and ecosystems, said Melanie Frazier, lead author of the new research and a University of Washington biology doctoral student.
Frazier, along with colleagues Raymond Huey, a UW biology professor, and David Berrigan, a former UW biology researcher now with the National Cancer Institute, said that shifts in population growth rates among insect species will have "profound ecological effects" by altering species composition and disrupting food webs. While some species will flourish, others will go extinct. "No matter which scenario plays out for a given species, local ecosystems will be profoundly altered," Frazier said.
