From: Tick range expansion to higher elevations: does Borrelia burgdorferi sensu lato facilitate the colonisation of marginal habitats?

Fig. 2

Tick abundance and Borrelia prevalence along elevation in the Swiss Alps. Abundance of questing Ixodes ricinus ticks in the vegetation (a) and prevalence of Borrelia burgdorferi sensu lato (b) and Borrelia afzelii (c) in I. ricinus nymphs at different elevations (m.a.s.l.) in the Swiss Alps. The colours of the dots represent the 3 dragging events per site while the size of the dots in (b) and (c) is proportional to the abundance of questing I. ricinus ticks (a). The grey area represents the range margin of I. ricinus ticks
