ABSTRACT

 

Recordings of frog calls from the genus Hylarana were conducted at seven study sites in Sarawak, Malaysia. The results showed that each species differs in terms of call characteristics, in which a high number of pulsed note belongs to H. baramica, while high repetition note belongs to the sibling species, H. glandulosa. Higher pitched and number of amplitude spectrum, however, belong to H. signata. Pulsed note and note repetition differed significantly among species, except for spectrum amplitude. Advertisement calls for each species were described in detail. This study provide a baseline data on advertisement call characteristics of frogs from the genus Hylarana for future studies of these frogs particularly and the Oriental frogs generally.

Keywords: Acoustic characteristic; amplitude spectrum; Hylarana, note; pitch; pulse

ABSTRAK

Rakaman panggilan katak daripada genus Hylarana telah dijalankan di tujuh kawasan kajian di Sarawak, Malaysia. Hasil kajian menunjukkan bahawa setiap spesies berbeza daripada segi ciri panggilan, iaitu nota yang bernada banyak ditunjukkan oleh Hylarana baramica, manakala nota berulang yang tinggi ditunjukkan oleh H. glandulosa. Nota yang berfrekuensi tinggi dan bilangan spektrum amplitud yang lebih tinggi dimiliki oleh H. signata. Nota bernada dan nada berulang berbeza dengan ketara di kalangan spesies, kecuali spektrum amplitud. Panggilan mengawan untuk setiap spesies diterangkan dengan terperinci. Kajian ini menyumbang kepada pangkalan data asas untuk ciri panggilan mengawan katak daripada genus Hylarana untuk kajian mengenai katak ini khususnya dan katak Oriental amnya.

Kata kunci: Ciri akustik; denyut; hylarana; nota; pic; spektrum amplitud
