Fig. 3From: The impact of temperature and precipitation on blacklegged tick activity and Lyme disease incidence in endemic and emerging regions a The density of questing nymphs (DON) per 100Â m2 determined via drag sampling compared against L-HDD, and b DON compared against N-HDD. Nymphs show lower activity during hot dry summers, but there is no effect of weather from the previous year. P-values and r 2 statistics are based on models including both the weather parameters and small mammal countsBack to article page
