ABSTRACT. Although Brazil encompasses one of the most abundant anuran faunas in the world, quantitative information on anuran ecology and diet are limited, especially in the Northeastern region. We analyzed the diet of six species: Hyla albomarginata, Hyla cf. branneri, Hyla minuta, Phyllomedusa aff. hypochondrialis (Hylidae), Leptodactylus natalensis, and Physalaemus cuvieri (Leptodactylidae) in a temporary pond in a rainforest remnant in Pernambuco, between 1999-2000. We analyzed diet composition, degree of food preference, and seasonal variations in diet. Leptodactylus natalensis and P. cuvieri showed higher diet diversity, whereas H. minuta consumed fewer food items. Insecta, Arachnida, and plants were preferential items for most species. Acari were consumed by all species; Hymenoptera, Odonata, and Coleoptera were also often consumed. A slight increase in diet diversity occurred in the rainy season. The species showed a generalist feeding behaviour, although P. cuvieri consumed Formicidae as major prey item.

Scriptosaura catimbau, a new genus and species of elongate, fossorial, sand swimming eyelid-less gymnophthalmid lizard is described on the basis of specimens obtained at Fazenda Porto Seguro, municipality of Buíque, State of Pernambuco, in the Caatingas of northeastern Brazil. The type locality is entirely included within the area of the recently created Parque Nacional do Catimbau. The new lizard lacks external forelimbs, has rudimentary styliform hindlimbs and is further characterized by the absence of prefrontal, frontal, frontoparietal and supraocular scales, and by having one pair of chin shields. A member of the Gymnophthalmini radiation, the new genus is considered to be sister to Calyptommatus from which it differs externally by the absence of an ocular scale and absence of an enlarged temporal scale.

As observações ocorreram no período de dois anos, monitorando grupos marcados de sagüis durante oito horas por dia. Foram registrados seis tipos de eventos: predação de sagüis; predação de aves, disputa de área de forrageio e recurso alimentar; compartilhamento de área de forrageio e recurso alimentar; perseguição branda e utilização de ninho de ave como local de pernoite dos sagüis. Os eventos agrupados obtiveram diferenças significativas entre as estações do ano e os estratos ocupados.

O presente trabalho registra mais uma espécie pertencente à família Leptodactylidae apresentando cuidado parental, Leptodactylus natalensis Lutz, 1930. Fêmeas foram observadas em assistência a ovos e cardumes de girinos em duas poças temporárias na mata Atlântica do Estado de Pernambuco, Brasil.

For Eretmochelys imbricata species, very little is known about the sex ratio of spawning which occur in the southern coast of Pernambuco. Therefore, the purpose of this study is to analyze the relationship between sexual development and temperature incubation of nests of hawksbill turtles deposited in Merepe Beach County Ipojuca, Pernambuco. The temperature data were collected from nine nests during the months from January to June 2013, with the aid of registers type temperature data loggers (Onset Computer Model, UA-001-08). The average recorded for nests sampled depending on the incubation period and temperature were 54 days and 31.68°C. Based on these results, the nests showed a strong trend towards the development of females, with the sex ratio, estimated by histological analysis, 86.53% for females. So the beach Merepe has temperatures that provide greater differentiation of newborn females. However, more detailed studies should be carried out with the intention of verifying whether these results can be obtained for any ipojucano coast.
