Climate change may allow mosquitoes, rodents to proliferate

Worcester Telegram  online


Unlike mosquitoes, evidence for climate change’s impact on tick populations and lifecycles is dubious, at best, according to Stephen Rich, a professor of microbiology at University of Massachusetts at Amherst. His research focuses on diseases that are maintained in animals, and sometimes transmitted to humans, such as Lyme disease and EEE.
