Center for Infectious Disease Dynamics, 208 Mueller Laboratory, Pennsylvania State University, Pennsylvania 16802, USA
Ecology 87:1981-6. 2006..We propose that localized absence of deer (loss of a dilution host) increases tick feeding on rodents, leading to the potential for tick-borne disease hotspots...
