概要 Local species diversity of auchenorrhyncha in Uminonakamichi Seaside Park, Fukuoka was surveyed by a sweeping method. A total of 16 species were collected. To estimate an optimum sampling size, collec...tor's curves of accumulated number of species were illustrated. The mean optimum size was 724.7 times of sweeping. This size was significantly correlated with the number of rarespecies. The lloys's index of each species collected was usually more than I and their spatial distributions were concentrated. The Iwao's overlaping index between collected species was distinctly less than I in any combination of paired species and their spatial distributions did not overlap. To survey effectively, one should move another better site just after collecting a few species.続きを見る
