Table 4. Numbers and percentile abundance of carabidae collected in ND area. Data are presented
according to altitude and part ofseason. N referes to the number of stations, each containing 5 pitfall
traps.
ing the three areas Kruskal-Wallis test was
used. To explain the significant differences
found in Kruskal-Wallis tests the different
groups were pair-wise analysed with Mann-
Whitney.
Results
Alltogether 3334 carabidae were collected;
consisting of 15 species. Belove all the found
species are listed in alphabetic order. For
each species the localities where they have
been found are given, these localities - ES,
NS and Ff - can be seen in Map 2. The num-
ber refers to altitude and letters e and w ref-
ere to south-eastern and north-western
riverside respectively, see Map 2 and Table 1.
Also some notes on the preferred habitats
are presented. Maps showing the distribu-
tion of each species are included.
