| The reproductive and feeding biology of the lined seahorse, Hippocampus erectus, was studied in Chesapeake Bay. Seahorses are monogamous, and males incubate the eggs received from females in a closed brood pouch (= marsupium). Females do not play any parental care after mating. Total sex ratio and the operational sex ratio was strongly skewed toward females. Males and females had similar number of eggs/embryos and hydrated oocytes, respectively. The number of eggs/embryos found in the male brood pouch varied from 97 to 1,552 (fish from 80 to 126 mm TL), whereas the number of hydrated oocytes in female varied from 90 to 1,313 (fish from 60 to 123 mm TL). Both, the number of eggs/embryos and hydrated oocytes were better linearly correlated to total weight... |

| Aspectos da ecologia de Tropidurus torquatus foram estudados mensalmente na restinga de Guriri, São Mateus, Norte do Espírito Santo, de fevereiro de 1996 a março de 1997. Foram coletados 108 exemplares com arma de pressão, sendo 45 machos, 56 fêmeas e 7 exemplares cujo sexo não foi identificado. O comprimento rostro-anal no total dos exemplares variou de 26,0 a 101,8 mm (média = 61,7 mm; DP = 15,1). O peso no total dos exemplares variou de 0,8 a 39,6 g (média = 14,6 g; DP = 10,4). Em freqüência de ocorrência, os itens alimentares que predominaram na dieta de T. torquatus foram as formigas (85,7%), coleópteros (32,4%), abelhas (31,4%), cupins (22,8%), aranhas (20,9) e flores (20,0%). Em relação à freqüência numérica, os itens alimentares que predominaram... |

| The diet of the arboreal lizard E. bilineatus was assessed based on analysis of gut contents of specimens collected in the remnants of the Atlantic rainforest in Espírito Santo State, south-eastern Brazil. Stomachs of the lizards examined (SVL = 57.0-85.0 mm) contained nine arthropod orders. E. bilineatus utilizes a broad range of arthopodan prey type and sizes, and can be considered an arthropod generalist, which uses a sit-and-wait foraging strategy. Orthoptera represented the most important food item, followed by Dictyoptera and Hymenoptera. Hemiptera, Homoptera, Lepidoptera (larvae), Coleoptera, Araneae, and Diplopoda constituted the remainder of food items. The presence of Diplopoda, which are not generally found on tree trunks, provides particularly... |
