Reliable Automation of Bat Call Identification for Eastern New South Wales, Australia, Using Classification Trees and AnaScheme Software

摘要: Accurate and efficient identification of bat (Microchiroptera) echolocation calls has been hampered by poor knowledge the intraspecific variability in (including regional variation), a lack call parameters for use separating species amount time required to manually identify individual or sequences. We constructed tested automated keys three regions New South Wales, Australia, using over 4,000 reference ≈300 sequences per region. used program AnaScheme extract time, frequency shape from recorded with Anabat system. Classification trees were built separate these provided decision rules construction keys. An ‘Unknown’ category was included that could not be confidently identified species. The reliability automatically AnaScheme, independent sets sequences, key...
