Seasonal trends in questing tick densities at high and low elevations in 2011 and 2012 in Møre og Romsdal county, Norway. The values on the y-axes are numbers of questing ticks collected per 20 m2 of flagging for each transect. The X-axes represent time. The trend is based on the best models from Table 1, and the intercept is the unadjusted estimate from the fixed effects. The red and black triangles show median questing tick density per transect for each bi-weekly flagging session. The red asterisks are predicted mean density of questing ticks for each bi-weekly flagging session (from a model with “transect” as random).
