“…By comparing our results with several similar works with gymnophthalmid lizards we can argue for some degree of historical conservatism, at least regarding D. nordestina and Ptychoglossus bicolor (Werner, 1916) (ANAYA-ROJAS et al 2010), Micrablepharus maximilianii (Reinhardt & Lütken, 1862), and Vanzosaura rubricauda (Boulenger, 1902) (D.C.P.S.

ABSTRACT. Life history parameters such as diet, reproduction, and sexual dimorphism are crucial to understand ecological and evolutionary forces shaping species traits. Nevertheless, such information is scant in the literature for most Neotropical squamates. Gymnophthalmidae contains over 242 species in 46 genera and includes small-size, mostly terrestrial species, although psamophilic, semi-aquatic, and low vegetation dwellers also occur. Dryadosaura is a monospecific genus -Dryadosaura nordestina Rodrigues et al., 2005 -, occurring in Atlantic Forest areas from Rio Grande do Norte to Northern Bahia, and little is known about its ecology and natural history. We analyzed the species' diet, reproduction, and sexual dimorphism based on 170 specimens deposited in museum collections. Dryadosaura nordestina is considered generalist and active forager, based on dietary items. Arthropods, especially ants and insect larvae, dominate the diet. The reproductive period shows a peak during the rainy season (May through June), while recruitment occurs from July through November. Males are significantly larger than females, and sexes can also be distinguished based on shape variables: males have higher heads and longer bodies, while body height and width are larger in females.

“…Anaya-Rojas et al (2010) studied the diet of Ptychoglossus bicolor and observed 11 prey types in its diet, which was mainly composed of isopods. The high proportion of Isoptera in the diet of Anotosaura vanzolinia is indicative of opportunistic behavior, as there were a large number of nests of these organisms in the study area.…”

Abstract:This study aimed to analyze the microhabitat use and diet of the lizard Gymnophthalmidae Anotosaura vanzolinia (Dixon 1974) in the Complexo Aluízio Campos (7° 16' 34" S, 35° 53' 7" W), an area of the Caatinga in the Campina Grande, Paraíba. We studied a total of 12 transects by active searching during the daytime. In each sample, habitat and microhabitat types occupied by the specimen were categorized, together with solar incidence and soil type. For all individuals, morphometric measurements were performed, as well as dissection for stomach content analysis. We collected a total of 46 individuals, with a snout-vent length ranging between 19 and 45 mm, collected over all habitats, with prevalence in soil and earthy litter microhabitats near rocky outcrops.The dietary analysis showed a use of items of soil fauna and identified 14 types of prey, mainly insects such as termites and ants. It was observed that smaller individuals (SVL < 30 mm) fed mainly on Hymenoptera (Family Formicidae), whereas larger individuals (SVL > 30 mm) selected Isoptera. Resumo: O presente trabalho objetivou analisar o uso do microhabitat e a dieta do lagarto Gymnophthalmidae Anotosaura vanzolinia (Dixon 1974) no Complexo Aluízio Campos (7° 16' 34" S, 35° 53' 7" W), uma área de Caatinga do município de Campina Grande, Paraíba. Foram estudados ao todo 12 transectos utilizando a metodologia de busca ativa diurna. Em cada expedição foram categorizados os tipos de habitat e microhabitat ocupado pelo espécime, além de dados de incidência solar e tipagem do solo. Para os indivíduos coletados, foram tomadas medidas morfométricas além da dissecação para análise do conteúdo estomacal. Foi coletado um total de 46 indivíduos, com um comprimento rostro-cloacal variando entre 19 e 45 mm, coletados ao longo de todos os habitats, com prevalência nos microhabitats com serrapilheira e solo terroso próximo a afloramentos rochosos. A análise da dieta evidenciou uma utilização de itens da fauna edáfica, sendo identificados 14 tipos de presas, principalmente insetos como cupins e formigas. Foi observado que indivíduos menores (CRC < 30 mm) alimentam-se principalmente de Hymenoptera (Família Formicidae) enquanto os indivíduos maiores (CRC > 30 mm) selecionaram Isoptera.

Biota Neotrop., vol. 13, no. 3 For the study, 12 quadrants of 100 m 2 were selected, which covered different types of vegetation and habitats. The lizards were caught during the dry season (March-April 2011) and the rainy season (July-August 2011) by an active diurnal search method (from 8.00 a.m. to 5.00 p.m.). At each site, rocks, timber, or other surface debris that might serve as lizard refuge sites, were lifted/rolled-over, in addition to making shallow excavations in the soil. To record the type of habitat and microhabitat where the specimens were found, we used the classification proposed by Delfim & Freire (2007). The habitats included: sparse shrubby vegetation, dense shrubby vege...

“…Por tales motivos, se sugiere que la variación observada respecto al volumen del contenido estomacal y frecuencia de consumo, es producto de la disponibilidad diferencial de presas en los distintos sitios de captura y no depende de las épocas de mayor o menor precipitación en el área de estudio. Al parecer H. frenatus en el área de estudio encuentra recursos alimentarios durante todo el año en cantidades que no fluctúan significativamente, como ha sido registrado para otras especies de lagartos en zonas tropicales (Rocha & Anjos, 2007;Anaya-Rojas et al, 2010;Caicedo-Portilla et al, 2010).…”
