Seasonal variations in distribution patterns and movements of bats in relation to habitat characteristics

摘要: Different types of land use, such as forestry and agriculture, change the distribution composition habitats in landscape. In order to understand consequences that for different organisms, find methods combining conservation with production crops, timber other products it is important collect information on pattern, habitat selection movements organisms. By using ultrasound detectors, mist-nets radio telemetry patterns, abundance species richness bats relation characteristics among forest patches "Lower Dniester" Ramsar Site, Republic Moldova was studied. The area consists mainly agricultural lands highly fragmented inundated upland remnants. each patch data were collected age, standing dead living trees, size patches, occurrence villages availability water. Data during two periods: July-August September-October, investigate potential seasonal differences selection. result shows pattern varies significantly seasons. During critical periods (late autumn), are restricted some specific key there between suboptimal habitats. A multivariate analysis revealed importance tree density. From this study, obvious play an role bat populations more needed improve bats.
