Breeding activity of Dendropsophus counani (Anura: Hylidae) in eastern Brazilian Amazonia
Keywords:
Clutches, eggs, reproductive mode.Abstract
The current knowledge on the natural history are still scarce for most species of Amazonian
anurans. Among these, the hylid Dendropsophus counani has incipient data on its breeding biology.
Herein, we studied the breeding biology of D. counani in the breeding seasons at Cancão
Municipal Natural Park, municipality of Serra do Navio, Amapá state. Males of D. counani
often start calling in the late afternoon (17:45 pm) and continue at night. All clutches had been
deposited on tree leaves (n = 8) and branches (n = 9) above the water, and after a few days the
eggs hatching into exotrophic tadpoles that dropped from the gelatinous clutch in lentic waters.
The number of eggs per egg clutch ranged from 40 to 153 eggs. Our study adds necessary data
about the natural history of this species, in addition to increasing the knowledge of the breeding
biology of Dendropsophus species.
