| diversity of bats in contrasting habitats of hulu terengganu dipterocarp forest and setiu wetland bris forest with a note on preliminary study of vertical stratification of pteropodid bats. | a study of the bat diversity was conducted in hulu terengganu dipterocarp forest and setiu wetland beach ridges interspersed with swales (bris) forest in terengganu, to study the species diversity, composition and stratification of fruit bats from the understorey to the forest canopy. mist nets were set up at the understorey, sub-canopy and canopy layer while harp traps were set up at the understorey layer. we recorded 170 individuals from six families' compromised 21 species from hulu terenggan ... | 2018 | 29644015 |
| regular pulse emission in some megachiropteran bats. | we recorded vocalizations of megachiropteran bats, cynopterus brachyotis, c. horsfieldi, megaerops ecaudatus and macroglossus sobrinus as they were held in our hands, in a hanging position or moved up and down, simulating flight. all four species produced regular audible tone pulses with a frequency spectrum of less than 9 khz (peak at 4-6 khz). the duration of a single pulse varied from 14.9 to 23.6 msec on average among these species. the interpulse interval was between 108.3 and 127.7 msec. i ... | 1995 | 8528020 |
