Fig VII-2. Example of the estimation of the decrease rate of the number of autochtonous, marked beetles in a pool (Wn)

d = number of days after release

p_d = minimum number of beetles present at d days after release, according to the curve number of marked beetles at least present:

* = in period 1

o = in period 2

in period 3

+ = in period 4
