Table 2 The abundance of Ixodes ricinus ticks per 20 m2 from flagging in two regions differing in incidence of tick-borne diseases; ‘east’ (Akershus and Østfold) and ‘west’ (Sogn & Fjordane) in Norway. We report full samples sizes, while only transects flagged all years were considered and restricted to below 200 masl to ease comparison of densities across areas

From: Tick abundance, pathogen prevalence, and disease incidence in two contrasting regions at the northern distribution range of Europe
