| We analyzed the diet and microhabitat use for two Hylodinae anurans (Cycloramphidae), Hylodes phyllodes Heyer & Cocroft, 1986 and Crossodactylus gaudichaudii Duméril & Bibron, 1841, living in sympatry at an Atlantic Rainforest area of Ilha Grande, in southeastern Brazil. The two species live syntopically at some rocky streams. The two species differed strongly in microhabitat use. Hylodes phyllodes occurred mainly on rocks, whereas C. gaudichaudii was observed mostly on the water. Regarding diet, coleopterans, hymenopterans (ants), and larvae were the most important prey item consumed by both species. Data suggest that microhabitat use appears to be an important parameter differentiating these frogs with respect to general resource... |

| We analysed patterns of skull size and shape variation among populations of the Common wall lizard (Podarcis muralis) in the Central Balkans, particularly the effecs of insularity and the presence of the ecologically similar lacertid lizard species P. melisellensis. Two components of shape variation were analysed – size dependent (allometric) and size independent shape changes. The observed shape differentiation relating to insularity was greatly size-dependent and concordant to allometric shape changes which explained over 20% of variation in the skull shape in the analysed sample. The explorative analysis of size-independent shape changes revealed that populations of P. muralis which share habitat with P. melisellensis diverge from populations which do... |

| We studied the feeding habits and microhabitat use of the Amazonian frogs Hyla minuta and Pseudopaludicula sp. at Serra Norte, Carajás, Brazil. Although living syntopically, the two species differed markedly in both prey types and sizes. Standardized feeding niche breadth of H. minuta (Bst = 0.572) was larger than that of Pseudopaludicula sp. (Bst = 0.149) and their feeding niche overlap was considerably low (10.5%). The two frog species also differed in microhabitat use. When active, Pseudopaludicula sp. were found partially submerged at the lake border whereas H. minuta were found predominantly on Nymphaea sp. leaves. Although we have not evaluated taxonomic effects on diet composition, differences in diet may be partially explained by differences in... |
