Ground spider diversity in the Kenting uplifted coral reef forest, Taiwan: a comparison between habitats receiving various disturbances

摘要: The effects of various disturbances on diversity and community structures ground spiders in the Kenting National Park uplifted coral reef forest were investigated using pitfall traps. In each following five sampling sites, ten trap stations established monitored once every month for a whole year: primary forest, with tourism activities, secondary grassland activities abandoned grassland. A total 2237 adult from 20 families 110 species collected, among which 86 (78.2%) new or newly recorded to Taiwan. Dominant can be divided into two major groups according temporal abundance variations: abundant dry season wet season. Habitat preference 12 dominant was assessed by comparing their relative between sites. Half exhibited strong habitat could only found habitats receiving no disturbance. Shannon–Weaver function, Simpson index Evenness not significantly different suggesting that these sites had similar structure characterized few numerous rare species. However, composition differed considerably Results UPGMA analysis pairwise Euclidean distance demonstrated specimens 50 four clusters: I II. Also, obtained, 61 distributed one site only, 11 16 unique addition composition, foraging guild also These results suggest KTNP is quite heterogeneous, any management activity should consider uniqueness type.
