| 英文摘要 | We studied the wing morphology, echolocation calls, foraging behaviour and flight speed of tylonycteris pachypus and tylonycteris robustula in longzhou county, south china during the summer (june-august) of 2005. the wingspan, wing loading and aspect ratio of the two species were relatively low, and those of t. pachypus were lower compared with t. robustula. the echolocation calls of t. pachypus and t. robustula consist of a broadband frequency modulated (fm) sweep followed by a short narrowband fm sweep. the dominant frequency of calls of t. pachypus was 65.1 khz, whereas that of t. robustula was 57.7 khz. the call frequencies (including highest frequency of the call, lowest frequency of the call and frequency of the call that contained most energy) of t. pachypus were higher than those of t. robustula, and the pulse duration of the former was longer than that of the latter. the inter-pulse interval and bandwidth of the calls were not significantly different between the two species. tylonycteris pachypus foraged in more complex environments than t. robustula, although the two species were both netted in edge habitats (around trees or houses), along pathways and in the tops of trees. tylonycteris pachypus flew slower (straight level flight speed, 4.3 m s(-1)) than t. robustula (straight level flight speed, 4.8 m s(-1)). we discuss the relationship between wing morphology, echolocation calls, foraging behaviour and flight speed, and demonstrate resource partitioning between these two species in terms of morphological and behavioural factors. |
