Dr. Péter Molnár, Ph.D., Assistant Professor in the Department of Biological Sciences of the University of Toronto Scarborough, a member of the IUCN Species Survival Commission Polar Bear Specialist Group, an Associate Editor for the Proceedings of the Royal Society of London Series B, and the Principal Investigator of the Laboratory for Quantitative Global Change Ecology. His research generally focuses on (i) documenting ecological and epidemiological impacts of climate change, land use change, and other anthropogenic disturbances, (ii) understanding the mechanisms by which environmental change impacts ecosystems, and (iii) formalizing these insights into forecast models that can inform proactive conservation and/or health management strategies. His approach is interdisciplinary, integrating physiological, ecological and epidemiological concepts within mathematical models, and combining these models with experimental and field data to examine complex dynamics in quantitative frameworks. Current research foci include (i) climate change impacts on large arctic mammals (primarily polar bears, muskoxen, caribou and moose), (ii) land use change impacts on large tropical mammals (primarily jaguars, pumas, ocelots and their prey), and (iii) climate change and land use change impacts on the distribution, spread, and impacts of mammalian parasites (e.g. nematode parasites of muskoxen and caribou in the Canadian Arctic Archipelago; winter ticks of elk, moose and deer in Yukon; helminth parasites shared between large cats and domestic dogs in Costa Rica).
