STUDY ON BIODIVERSITY OF CARABIDAE IN BACH MA NATIONAL PARK, THUA THIEN - HUE PROVINCE.

Abstract

             This study has defined 321 individuals of 33 species and 24 genera of Carabidae. In particular, almost genera have the minimum number of species of one species. The genus of Chlaenius has the most number of species with five species. Rare species group (R) is mainly in three habitats, which are Grassland (5/7 species), Generating forest (10/22 species) and Stream side (4/10 species) habitats. In Shrub, the Uncommon species (U) have vast majority (8/15 species). Particularly, common species group (C) has the least number in all habitats. The species diversity index and biodiversity index are highest in Generating forest (d = 4.197, H’ = 2.77) and lowest in Grassland (d = 1.701, H’ = 1.63). The pielou Index is highest in Shrubs (J’ = 0,9101) and lowest in Grassland (J’ = 0.8377). despectively. The group of Generating forest and Shrubs has the highest similarity index of species composition (SI = 43.59%). This index are lowest in between Grassland and Stream side (SI = 9.09%). The genus of Carabidae is not distributed widely; only Chlaenius is distributed in four habitats. Four genera distributed in three habitats is Platymetopus, Ophionea, Lebia and Dischissus. The other genera are distributed in one or two habitats only.
