Bat communities in a fragmented forest landscape on the south-west slopes of New South Wales, Australia

摘要: Abstract Ultrasonic detectors were used to compare bat activity and species richness at replicated continuous isolated forests, large small remnants, corridors open areas on the south-west slopes of New South Wales, Australia. The habitat matrix in this area consists primarily agricultural land interspersed with indigenous forest remnants pine plantations. Ten taxa recorded, fewest corridors. A multivariate analysis revealed that a gradient area, diversity structural complexity was most consistent predictor for four (C. morio, Nyctophilus spp., V. regulus F. tasmaniensis), suggesting these are sensitive effects fragmentation. Six (N. australis, M. planiceps l.p., C. gouldii, schreibersii, darlingtoni, vulturnus) appeared tolerant fragmentation not isolation effects. Most active over probably resources mosaic. Typically they fast flying, low manoeuvrability which predicted forage uncluttered habitats. Although total as great forests 690 000 ha national park, feeding greatest larger high offered more foraging opportunities. Despite providing fewer opportunities, represent an important conservation resource bats because is concentrated here provide potential roost sites. Activity each significantly lower than (non-riparian), regularly by move through landscape. More detailed studies movements identified would help explain how affects thus what measures required improve their conservation.
