“…Leptodactylus labyrinthicus tadpoles reach a large size within the nest through consumption of trophic eggs, but complete their metamorphosis in water, where they prey upon anuran eggs and tadpoles or feed on carrion (Cardoso and Sazima, 1977;Agostinho et al, 2002;Prado et al, 2005;Shepard and Caldwell, 2005;Silva and Muniz, 2005;Zina and Haddad, 2005).

Leptodactylus labyrinthicus tadpoles reach a large size in the nest through consumption of trophic eggs. We previously suggested that the trophic eggs are laid just after amplexus has finished, but our new data do not support this hypothesis. We also present further details on the natural history of the species with regard to breeding activity, spawning site, retreats and the ability of tadpoles in preying upon fully-growth heterospecific tadpoles. We also show that the tadpoles are mainly nocturnal and take diurnal refuges. We collected the data in Brazil in three localities within the Cerrado Biome. We examined burrows used by L. labyrinthicus males, verified if females still contained mature eggs just after released from amplexus, and tested the ability of tadpoles in preying fully-growth heterospecific tadpoles. Field observations and experiments were conducted on tadpole activity time, hiding behaviour and level of susceptibility to predation by the bird leaf-scrapers in four sheltering situations. Reproduction could start before the first rains; this may be advantageous by allowing the tadpoles to exploit eggs of other frogs. We found one floating nest built in a temporary pool. The nest of the species is normally circumscribed in an excavated basin beside the water body. Adult males were found during the day with their head-out of the entrance of underwater burrows, which were perforations through dense root mats beside calling/spawning sites. Probably, these burrows in permanently water-filled soil are actively excavated by males. Females released all their eggs during the amplexus, so trophic eggs are not produced by the currently-accepted mechanism. Fully-grown heterospecific tadpoles were not preyed upon by L. labyrinthicus tadpoles, which can prey only slow-moving newly hatched ones. Field tadpoles took shelter under mud/dead leaves during daylight and became exposed on the bottom at night. Free-ranging leaf-scrapers removed dead leaves from a pool with their beaks and preyed upon tadpoles. In the experiments, the tadpoles sheltered under gravel/leaves during daylight, but they were exposed at night. Leaf-scrapers ate all exposed tadpoles, but no tadpole of the gravel/leaves trays was consumed. Hence the nocturnal habits and use of diurnal refuges may protect the tadpoles from visual predators, such as the leaf-scrapers.Keywords: Leptodactylus pentadactylus group, reproduction, retreats, trophic eggs, tadpoles.

RESUMO:A família Leptodactylidae depositam seus ovos em ninhos de espuma, que dentre outras funções, poderiam participar da manutenção de temperaturas adequadas para o desenvolvimento de ovos, embriões e larvas. O trabalho estudou as variações térmicas entre os ninhos de oviposição de Leptodactylus labyrinthicus e ar externo. Foram realizadas medidas de temperatura do ar, a 10 cm e do fundo da espuma para 4 ninhos nos seguintes períodos: 10h; 14h; 18h e 22h horas de um único dia. As temperaturas do ar mostraram-se significativamente acima daquelas do fundo dos ninhos, exceto para o período das 22h horas, mostrando-se iguais. As temperaturas do fundo não diferiram entre si para os períodos das 12he 22h horas. Conclui-se que os ninhos de espuma de L. labyrinthicus mantiveram suas temperaturas internas a valores abaixo dos atmosféricos externos.Palavras-Chave: Temperatura do ar.

SUMMARY:The Leptodactylidae family lay their eggs in foam nests, which, among other functions, could participate maintaining appropriate temperatures for the development of eggs, embryos and larvae. The work studied the thermal variations between the nests of oviposition of Leptodactylus labyrinthicus and outside air. Measurements of air temperature at 10 cm above and the bottom of the foam to four nests were conducted during the following periods: 10h; 14h; 18h and 22h hours of a single day. Air temperatures were significantly above those of the bottom of the nest, except for the period from 22h, being equal. The temperatures of the background did not differ for the periods 12hand 22h hours. It is concluded that the foam nests of L. labyrinthicus kept their internal values below the external atmospheric temperatures.

“…In Venezuela, Péfaur and Sierra (1995) suggested that L. labyrinthicus populations may be susceptible to decimation because the species is economically attractive, since adults are large, easily captured, and distributed only in a small area of the country. The hunting pressure exerted by humans also was considered by Zina and Haddad (2005) as the most likely hypothesis to ISSN: 1809-127X…”
