Aerodynamics, kinematics, and energetics of horizontal flapping flight in the long-eared bat Plecotus auritus.
The kinematics, aerodynamics, and energetics of Plecotus auritus in slow horizontal flight, 2-35 m s-1, are analysed. At this speed the inclination of the stroke path is ca. 58 degrees to the horizontal, the stroke angle ca. 91 degrees, and the stroke frequency ca. 11-9 Hz. A method, based on steady-state aerodynamic and momenthum theories, is derived to calculate the lift and drag coefficients...
متن کاملEffects of body mass and reproduction on the basal metabolic rate of brown long-eared bats (Plecotus auritus).
We measured basal metabolic rate (BMR) of nonreproductive and of breeding (pregnant and lactating) female brown long-eared bats (Plecotus auritus) to investigate the effects of intra- and interindividual variation in body mass and of reproduction on metabolism. The BMR of six nonreproductive females was measured between five and seven times at approximately 2-wk intervals over a period of 2.5 m...
متن کاملThe reproductive cycle and determination of sexual maturity in male brown long-eared bats, Plecotus auritus (Chiroptera: Vespertilionidae)
Observations of the external morphology of wild-caught and captive male brown long-eared bats (Plecotus auritus) revealed a marked seasonal pattern of spermatogenesis, similar to that established by histological examination of other temperate-zone vespertilionids, with a peak in testes size in August and a lag between testicular growth and epididymal distension. This was followed by complete ce...
متن کاملThe Foraging Ecology of the Mountain Long-Eared Bat Plecotus macrobullaris Revealed with DNA Mini-Barcodes
Molecular analysis of diet overcomes the considerable limitations of traditional techniques for identifying prey remains in bat faeces. We collected faeces from individual Mountain Long-eared Bats Plecotus macrobullaris trapped using mist nets during the summers of 2009 and 2010 in the Pyrenees. We analysed their diet using DNA mini-barcodes to identify prey species. In addition, we inferred so...
متن کاملHabitat use in the female Alpine long-eared bat (Plecotus macrobullaris): does breeding make the difference?
Recent discoveries of several new, cryptic bat species in Europe, and the growing importance of bat conservation have resulted in an increased research effort to study roost site selection, habitat use and spacing/foraging behaviour of (rare) bat species (Arlettaz, 1999; Mayer and von Helversen, 2001; Mickleburgh et al., 2002; Di Salvo et al., 2009; Whitaker and Karataş, 2009). In fact, before ...
