Recorded and resampled estimates of peak and total nymphal tick abundance in 2009 at five plots in southern England. For each plot: Graph (a) shows the peak nymphal activity in 2009 (model data created by daily interpolation of three-weekly tick data collection); graph (b) shows the ranges of peak nymphal activity values for the 21 possible three-weekly sampling regimes of the model data for each plot; graph (c) shows ranges of activity values taken on all possible single-sample dates within a 61-day window centred on the recorded peak at each plot the previous year; graph (d) shows ranges of activity values taken on all 31 possible double-sample dates within the same 61-day window; graph (e) shows the area under the graph (AUTG – see text) values of the model data series; graph (f) shows the distribution of AUTG values for the three-weekly sampling regimes of the model data.
