Abstract

GIARETTA, Ariovaldo A  and  CARDOSO, Adão J. Reproductive behavior of Cycloramphus dubius Miranda-Ribeiro (Amphibia, Anura, Leptodactylidae). Rev. Bras. Zool. [online]. 1995, vol.12, n.2, pp.233-237. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751995000200002.

Cycloramphus dubius Miranda-Ribeiro. 1920 is a frog species from the coastal Atlantic Forest in Southeastern Brazil. It uses waterfalls of forested rivulets as breeding sites. The eggs are placed outside of water, between rock crevices or roots constantly wetted by water dripping. Clutches have about 60 eggs, and the tadpoles grow attached to rocks, out of water. Males of this species exhibit parental care, biting and/or pushing away strange objects approaching the egg masses. Two types of calls were identified in the spectrograms. The "advertisement calls" consist of juxtaposed pulses lasting 200ms; the "aggressive calls", also have the short pulses structure, and last around 300ms. The aggressive calls are emitted during territorial invasion.

Keywords : Amphibia; Anura; Atlantic Forest; breeding site; territoriality; parental care.
