were considered highly suitable patches, with a mean area of 0.921 ± 0.698 (SD) ha, which accounted for
122,090 ha (2.04%) of the study area. Roosting sites predicted from the model were consistently associated
with occurrences of roosting sites observed in temples; such habitats likely provide shelter from external

For a broad-scale component, environmental factors of a vegetational nature are more important, for medium-scale, edaphic factors are more important, for fine-scale, both vegetation and edaphic are important.

a positive effect on the reproduction and surviving of both taxonomic groups in the subsequent vegetation
season. We have discovered the positive correlation between the temperature and the quantity dynamics of
