One of many sessions that will focus on species interactions at ESA’s 2013 Annual Meeting by Nadine Lymn, ESA director of public affairs Human cases of Lyme disease continue to rise in the United States. The bacterial disease—which, if untreated can cause significant neurological problems, is transmitted to people by black-legged ticks, which pick up the pathogen by feeding on…
