Because of their impressive and vibrant color combos, they’re sometimes called “clown frogs.” LONG MATING SEASON Pairs can be in amplexus HARD TO SPOT (the frog mating hug) for a few weeks, during Many species are hard to see which time the males because individuals are spread often forgo food in their out in dense forest. But they commitment to breed, are quite conspicuous during losing up to 30 percent the breeding season when they of their body weight! all come down to the streams in search of potential mates. ON THE SMALL SIDE The smallest species of harlequin toads measure about an inch in length. Overall the group of toads range in size from that of a human baby’s Toad Mountain Harlequin frog (Atelopus certus) © Brian Gratwicke thumb to that of an adult thumb.

  • Vocalizations of Eight Species of Atelopus (Anura: Bufonidae) with Comments on Communication in the Genus
    Copeia, 1990(3), pp. 631-643 Vocalizations of Eight Species of Atelopus (Anura: Bufonidae) With Comments on Communication in the Genus REGINALD B. COCROFT, ROY W. MCDIARMID, ALAN P. JASLOW AND PEDRO M. RUIZ-CARRANZA Vocalizations of frogs of the genus Atelopus include three discrete types of signals: pulsed calls, pure tone calls, and short calls. Repertoire composition is conservative across species. Repertoires of most species whose calls have been recorded contain two or three of these identifiable call types. Within a call type, details of call structure are very similar across species. This apparent lack of divergence in calls may be related to the rarity of sympatry among species of Atelopus and to the relative importance of visual communication in their social interactions. COMMUNICATION in frogs of the genus lopus by comparing the structure and behavioral Atelopus has been httle studied despite sev- context, where available, of calls of these species eral unique features of their biology that make with calls of other species reported in the lit- them an important comparative system in light erature. of the extensive work on other species of an- METHODS urans (Littlejohn, 1977; Wells, 1977; Gerhardt, 1988).

Two new species of Atelopus (harlequin frogs) are described from the Andes of northern Peru, one from the northern Cordillera de Huancabamba (Departamento de Piura), 2,950 m elevation, and the other from an inter-Andean valley of the upper Marañon basin, Cordillera Central (Departamento de La Libertad), 2,620 m elevation.

This species is endemic and endangered, so information about its ecology and distribution are crucial for the conservation of this toad. Here, the relative abundance, habitat and microhabitat uses, and vocalization of A. laetissimus are described from the San Lorenzo creek in the SNSM, as well as its potential distribution in the SNSM. To this end, 447 individuals were analyzed during several sampling trips from 2010 to 2012. Against expectations, population density was signifcantly higher in the stream than in the riparian forest. Overall, A. laetissimus used seven different diurnal microhabitats, with a high preference for leaf litter substrates and rocks.
