2005
Vician, V.
Ground beetles (Coleoptera, Carabidae) of Nefcerka valley were studied within 3 sampling sites along an elevational gradient. A total of 499 specimens were identified to 11 species. The most abundant species was Pterostichus mario carpathicus (176 ind., 35,5 %) followed by Trechus pulchellus (90 ind., 18 %) and Pterostichus anthracinus (86 ind., 17,2 %). Carabid assemblages within forest site were the poorest with respect to both the number of species and abundanee. More diverse and abundant fauna of carabids was found on sites situated on sparse dwarf pine stands and alpine meadows A correlation beetween abundance and altitude was obserwed by Trechus pulchellus and Nebria tatrica, respectively. Trechus pulchellus was most abundant at the lowest site and its abundanee continuosly decreased towards the highest, contrary to Nebria tatrica with abundanee negatively correlated to altitude.
