Fig. 7. Daily estimates of the number of beetles at the Jagersveld site in 2001 and 2007 according to the POPAN formulation of the Jolly-Seber method, under the acceptance of constant survival and capture probabilities over time. Minimum daily number of known survivors (MNA). Rainy periods and, for 2001, stormy evening episodes, are figured at the bottom of the graphs.
