Diversity and seasonal change of Carabid Beetle Assemblages in Hallyeohaesang National Park

This study was conducted to investigate diversity and its seasonal change of carabid beetles in the Hallyeohaesang national park, especially in forest environments. A total of 15 sites were selected. As islands, 5 sites in Namhaedo, 4 sties in Tongyeong, 3 sites in Geojedo, 1 site in Odongdo and Neukdo were selected and 1 site in Mt. Geumo in Hadong-gun was selected as mainland. Sampling was conducted by pitfall traps from June to October in 2014. A total of 1,072 individuals belonging to 25 carabid beetle species were collected. In most islands, Synuchus nitidus was dominant, but subdominant species was different depending on islands. In number of species, 15 carabid beetle species were collected in Namhaedo that was the highest following by Tongyong (14 species), Neukdo (10 species), Geojedo (9 species), Mt. Geumo (mainland, 6 species), and Odongdo (4 species). Number of species and abundance were generally increased from early summer to autumn. In consequence, we added 12 carabid beetle species to the insect fauna of Hallyeohaesang national park, and it is expected that more insect species can be found considering by environmental characteristics and seasonality of islands.
