Envisioning Climate Change Impacts on the World’s Deadliest Animals

Presented as part of the Climate, People and the Environment Program, presented by the Nelson Institute Center for Climatic Research.

Each semester the Climate, People, and the Environment Program hosts a weekly seminar featuring lectures by visiting speakers as well as presentations by CPEP faculty, scientists, and students. In some semesters the CPEP Seminar has a unifying theme and, in addition to speakers, weekly meetings may serve as workshops to discuss research issues and be a springboard for collaborative papers. CPEP seminar presentations are held in conjunction with the Department of Atmospheric and Oceanic Sciences (AOS) and are open to the public. Events are listed on the Environmental Eventscalendar by the Nelson Institute and posted in AOS and other relevant departments.

This week’s speaker is Lyric Bartholomay, Director of the Upper Midwestern Regional Center of Excellence for Vector-Borne Disease; Department of Pathobiological Sciences, School of Veterinary Medicine, University of Wisconsin-Madison.

Ever-warming global temperatures expand the potential habitat range of mosquito species, with clear public health implications when those species are competent vectors for human and animal pathogens. In 2017, an invasive mosquito, associated with transmission of Zika virus, was found for the first time in Wisconsin. This invasion provides unique opportunity to interrogate the capacity of a mosquito to adapt to Wisconsin winter temperatures, and prompts questions about the stresses of extreme temperatures on cold-blooded insect species.
