| This work was carried out in Marco river, São José dos Ausentes municipality, state of Rio Grande do Sul, southern Brazil. This region is located within the Campos Sulinos biome, an area of great biological importance due to its high diversity and endemism of fish. The feeding habits and food overlap between Eurycheilichthys pantherinus (Reis & Schaefer, 1992) (n=108) and Pareiorhaphis hystrix Pereira & Reis, 2002 (n=60) are described. Monthly samples were obtained between September 2000 and July 2001 with dipnets using the kick sampling technique. Stomach contents were analyzed based on frequency of occurrence, volumetric frequency and index of alimentary importance. The level of dietary specialization and food overlap were determined by... |

| Trogons are pan-tropical forest birds that eat a mix of fruits and arthropods. With direct observations of wild feeding birds, I assessed the relative contribution of fruits and arthropods to the diet of three trogon species (Trogonviridis, T.surrucura, and T.rufus) at Parque Estadual Intervales, southeast Brazil. Fruits and arthropods made the bulk of the food items recorded, with a tendency of frugivory increasing with body mass. The Trogon species differed in the proportion of fruits and arthropods taken, with T.viridis being the most frugivorous species (66% of feeding bouts, n = 47). The relative contribution of fruits and arthropods did not differ between the wet and dry seasons for any species. In the omnivorous gradient, T.viridis is close to the... |

| We examined food habits of Vespertilionidae bats Myotis nigricans (Schinz, 1821) and Eptesicus furinalis (d'Orbigny, 1847) by fecal analysis in cerrado sensu stricto and gallery forests, within APA - Gama-Cabeça-de-Veado, Brasília, Distrito Federal, Brazil. Out of 20 fecal samples collected, seven were of Eptesicus furinalis and 13 of Myotis nigricans. The diet of E. furinalis included six orders of insects: Coleoptera (5/7 by items presence), Lepidoptera and Hymenoptera (3/7), Diptera, Hemiptera and Homoptera (1/7). The diet of M. nigricans included all the main orders consumed by E. furinalis (6/13, 4/13, 4/13, 3/13, 1/13, and 4/13 respectively) and one other order: Orthoptera (1/13). Homoptera, Diptera and Orthoptera were collected only in bats captured... |
