Postnatal development of morphological and vocal features in Asian particolored bat, Vespertilio sinensis

摘要: Abstract We studied the postnatal development of morphological and vocal features in a free-ranging population Asian particolored bat, Vespertilio sinensis. There were no significant differences growth rates between males females on basis changes. Body mass forearm length followed linear pattern until 28 days age at mean 0.38 g/day 1.15 mm/day, respectively thereafter increased slowly. The total epiphyseal gap fourth metacarpal–phalangeal joint initially showed increase for up to 16 days, by decrease day 46 rate 0.18 mm/day. When was used combination with changes length, we derived reliable estimation equations 1–46 day range. Of three nonlinear models (logistic, Gompertz, von Bertalanffy), Bertalanffy logistic provided best fit empirical curves body respectively. Studies that infants could emit short calls as precursors echolocation after birth. Isolation both characterized multiple harmonics. observed systematic value starting frequency without change terminal over 3 week period development. In addition, duration isolation 4 then decreased, whereas, decreased continuously reach stable level.
