Fig. 10 in Demographic data on a stag beetle (Lucanus cervus) population self-established in an artificial suburban habitat

Fig. 10. Yearly number of stag beetles found dead by predation at the Jagersveld CMR site during the period 2001- 2023. Areas in grey refer to predation by Corvids, areas in yellow to predation by hedgehogs. The annual sex-ratio measured on these beetle remains is indicated, as is the yearly total number of beetles killed by predators and the total number of natural deaths.

Fig. 9. Variation, as a function of year, of the mean and standard error of head width (KB) of males found dead at the Jagersveld CMR site. Numbers indicate the size of the samples, and letters and colors indicate samples not significantly differing in size from each other at the P = 0.05 threshold, by using the non-parametric Kruskal-Wallis test for multiple comparisons. Samples of years 1924 and 2021 were excluded from the K-W analysis.

Fig. 4. Cumulative number of new individuals at the Jagersveld site during the CMR sessions of 2001 and 2007. (a): appearance of the first males. (b): geometric increase of new individuals during a short period. The graphs in the right insets show this increase in semi-logarithmic coordinates. (i): inflection point. (c): more regular increase of new individuals until reaching (d) a plateau (p). The increase of new females was more progressive.

Fig. 3. Calendar of male capture and recapture histories at the Jagersveld site. The marked individuals are sorted by date of first capture and by known duration of longevity. 1: captured. 0: not encountered in the interval where the individual was known to be alive. +: found dead by predation on the sampling site. *: natural death. MNA: minimum number known alive.
