Description:

An experiment was carried out on a 4 ha, foot-shaped, Crabapple Island: at the most distant places (270 m) two trap lines were set. After 5 days of trapping (The CMR method was used) the lines were replaced by a grid with traps that uniformly covered the entire island area. The grid was used during 7 days. The trap lines revealed 13 individuals, through there were 87 individuals shown by the grid method. The results obtained with the lines misestimated the population structure: immatures were not caught, through there were 32 of them; the sex ratio among mature individuals revealed by the trap lines was 6 males to 7 females, whereas the sex ratio from the grid method was 21 to 34.
