Abstract
|
|
|
|
Since specific types and physical characteristics of anuran calls can represent reproductive qualities of a calling male, anuran calls have been studied in context of mate choice. We in here report call types of Rana dybowskii and their variations from two different recording sites. Calls of R. dybowskii are classified to three types based on their physical characteristics and behavioral observations: ´A-call´ functions to advertise locations of a calling male and to attract potential mates. A territorial male emits ´B-call´ only during male-male interaction. ´C-call´ is released when a male frog was clasped by another male. The A-call from two recording sites, Miwon and Wonju, shows high variations in their call characteristics.
