No apparent ecological trend to the flight-initiating jump performance of five bat species.

摘要: The jump performance of five insectivorous bat species (Miniopterus schreibersii, Myotis blythii, capaccinii, myotis and Rhinolophus blasii) was filmed using a high-speed camera. All study bats jumped similar technique, with the wing musculature providing force. off wrist joint their wings, typically feet already ground. Contrary to expectations, did not correlate ecology instead strongly determined by body size. In general, larger produced more force, left ground at higher speeds than smaller bats. differences in force production disappeared when data were corrected for size, exception which significantly less Scaling size measured here compared against two existing muscle scaling models. model suggesting that contraction velocity is proportional length better supported based on cross-sectional area. Both models, however, failed accurately predict forces, slope relationship being steeper predicted, highlighting need further investigations vertebrate scaling. results this indicate bat's jumping ability secondary locomotor uses selected-for flight apparatus no apparent ecological trend present, i.e. so dominates morphology other abilities tend be derivative.
