geographical variation in echolocation call and body size of the okinawan least horseshoe bat, rhinolophus pumilus (mammalia: rhinolophidae), on okinawa-jima island, ryukyu archipelago, japan.	the okinawan least horseshoe bat, rhinolophus pumilus, is a cave-dwelling species endemic to the central and southern ryukyus, japan. we analyzed variation in the constant frequency (cf) of the echolocation call and in forearm length (fal) of this species on okinawa-jima island on the basis of data for 479 individuals from 11 caves scattered over the island. cf values in samples from six caves, all located in the southwestern half of okinawa-jima, were significantly higher than those in samples ...	2006	16971783
genetic and acoustic population structuring in the okinawa least horseshoe bat: are intercolony acoustic differences maintained by vertical maternal transmission?	the origin and meaning of echolocation call frequency variation within rhinolophid bats is not well understood despite an increasing number of allopatric and sympatric examples being documented. a bimodal distribution of mean regional call frequency within the okinawa-jima island population of rhinolophus cornutus pumilus (rhinolophidae) provided a unique opportunity to investigate geographic call frequency variation early in its development. individual resting echolocation frequencies, partial ...	2008	19120986
