Abstract
Diet and habitat selection of several species of insectivorous bats were st udied in the Dead Sea area. Israel. Significant differences in diet composi tion were found among the species studied. Long-eared bats (Plecotus austri acus and Nycteris thebaica) tended to feed on Lepidoptera, and N. thebaica also on Diptera; Asellia tridens and Rhinolophus clivosus on Coleoptera and Hymenoptera; Rhinolophus hipposideros on Lepidoptera and Diptera; Eptesicu s bottae on Hymenoptera and Lepidoptera; Pipistrellus bodenheimeri and Pipi strellus kuhlii on Diptera and Lepidoptera; and Pipistrellus rueppellii on Diptera. Dietary niche breadth (B-%V) was widest for P. bodenheimeri and na rrowest for P. austriacus. There were significant species-related differenc es in habitat utilization. Tadarida teniotis and Rhinopoma hardwickei forag ed almost exclusively in open areas: 'over water' habitat was preferred by P. rueppellii and utilized extensively also by I? bodenheimeri; 'near stree t lights' and 'edges of vegetation and cliffs' by P. kuhlii; 'edges of vege tation and cliffs' by Il bodenheimeri and E. bottae; and 'cluttered environ ment' by A. tridens, R. hipposideros, and R. clivosus. Community structure of these bats is discussed.
