All the Abiotic and Biotic factors are describ in short language. The CFs of these species range between 40 kHz and 200 kHz, but the distribution of call frequencies is not random: frequencies lying close together are avoided, suggesting that resource partitioning may occur with respect to prey size as a mechanism for reducing interspecific competition for insect food (Heller and Helversen, 1989). 1.
