Abstract
In this study, we investigated the usefulness of Vargula hilgendorfii as an indicator species from the community structure of benthos. The study areas included 36 stations at 5 sandy beaches in southern Osaka. The occurrence of benthos and environmental conditions were assessed by the Smith-McIntyre grab sampler. 142 species were identified from 3350 benthos. According to the results of two-way indicator species analysis (TWINSPAN), identified species were classified into 7 community types, and stations were classified into 6 groups. The community type to which V. hilgendorfii belongs included rare species and species for fisheries. As the results of indicator species analysis (INSPAN), V. hilgendorfii was extracted as an indicator species of a group I that much of benthos appeared. And the frequency of V. hilgendorfii in the group I (89.7%) was the highest among indicator species extracted by INSPAN. In addition, as 6 groups were ordered by detrended correspondence analysis (DCA), it revealed that the group I had the extremely narrow condition that sandy bottom is oxidized. These results suggested that V. hilgendorfii is useful as an indicator species of the sandy beach where should be given priority to conservation for benthos.
