“…Theoretical relationships between wing morphology, flight behavior, forage strategies and forage habitats among bat species have been suggested (Ald ridge and Rautenbach, 1987;Norberg and Rayner, 1987;Fenton, 1990;Jennings et al, 2004;Jones et al, 2006;Zhang et al, 2007). For T. melanopogon, aspect ratio and wing loading were high, wing-span was long, while tip length ratio, tip area ratio and wing tip shape index were low.…”

“…DF was measured from power spectra, Start-F and End-F from spectrograms, and PD and IPI from oscillograms following Zhang et al (2007). On the basis of DC values, each bat was placed into one of three categories: low (≤ 5%), average (5-10%), and high (≥ 10%) based on Jennings et al (2004).…”

“…Aspect ratio (A), wing loading (WL), and wing tip shape index (I) were calculated following Zhang et al (2007) and Norberg and Rayner (1987). We also categorized aspect ratio, wing loading and wing tip shape index as low, average or high, following Jennings et al (2004): 1. Aspect ratio: low ≤ 6.1, average = 6.1-7.3, high ≥ 7.3; 2.…”

We studied the wing morphology, echolocation calls, diet and emergence time of the black-bearded tomb bat (Taphozous melanopogon) from May to October 2006 in Guangxi Province, southwest China. Taphozous melanopogon has wings with high aspect ratio, high loading and pointed wing-tip shape-characteristics associated with fast flight in open space. This species usually produces low-intensity, low frequency, and frequency-modulated (FM) calls usually containing up to four harmonics, with most energy in the second (or sometimes third) harmonic. The diet of this species consists mostly of Lepidoptera and Hemiptera. Timing of evening emergence is correlated with the time of sunset. This is the first study to describe the flight and echolocation behavior of this species in China, and opens the way for future studies of its biology.

“…In an ecomorphological study, Jennings et al (2004) stated that N. stramineus stramineus can fly very slowly in clutter and that it hunts by slow hawking and/or by gleaning. They found that N. stramineus produced multiharmonic FM echolocation calls with most energy in the second harmonic.…”

“…The greatest energy of the fundamental frequency was centered around 60 kHz, and that of the second harmonic at 90-100 kHz. The duty cycle was intermediate (Jennings et al, 2004).…”

Dispersal is a driving factor in the creation and maintenance of biodiversity, yet little is known about the effects of habitat variation and geography on dispersal and population connectivity in most mammalian groups. Bats of the family Molossidae are fast‐flying mammals thought to have potentially high dispersal ability, and recent studies have indicated gene flow across hundreds of kilometers in continental North American populations of the Brazilian free‐tailed bat, Tadarida brasiliensis. We examined the population genetics, phylogeography, and morphology of this species in Florida and across islands of The Bahamas, which are part of an island archipelago in the West Indies. Previous studies indicate that bats in the family Phyllostomidae, which are possibly less mobile than members of the family Molossidae, exhibit population structuring across The Bahamas. We hypothesized that T. brasiliensis would show high population connectivity throughout the islands and that T. brasiliensis would show higher connectivity than two species of phyllostomid bats that have been previously examined in The Bahamas. Contrary to our predictions, T. brasiliensis shows high population structure between two groups of islands in The Bahamas, similar to the structure exhibited by one species of phyllostomid bat. Phylogenetic and morphological analyses suggest that this structure may be the result of ancient divergence between two populations of T. brasiliensis that subsequently came into contact in The Bahamas. Our findings additionally suggest that there may be cryptic species within T. brasiliensis in The Bahamas and the West Indies more broadly.
