Identification of British bat species by multivariate analysis of echolocation call parameters

摘要: ABSTRACT 1. A method for the identification of bat species from time-expanded broad-band recordings their echolocation calls is presented. The may be used assessment habitat use by bats. 2. Recordings were made produced 536 bats known identity, belonging to 15 found in Great Britain. One call was analysed per individual, and sonograms descriptive statistics six time frequency variables are British can placed three groups according structure calls: high duty cycle FM/CF/FM (Rhinolophus spp.), low FM (Myotis spp. Plecotus spp.) intermediate FM/CF (Pipistrellus Nyctalus Eptesicus serotinus). 3. could identified peak calls. Two separate quadratic multivariate discriminant analyses carried out on parameters For ba...
