| Obteve-se 37 tipos de galhas entomógenas, morfologicamente distintas, em 22 espécies de plantas arbustivas e arbóreas do Campus-Pampulha da U.F.M.G., Belo Horizonte - Minas Gerais. A maior parte delas são dipterocecídias causadas por cecidomiídeos, principalmente em folhas. A morfologia externa das galhas é extremamente variável, embora internamente seja mais uniforme. O número de galhas por órgão varia enormemente entre plantas, embora o número de lojas e larvas por lojas seja mais freqüentemente igual a 1. Várias famílias de parasitóides, principalmente das dipterocecídias, foram também obtidas. |

| Study carried out within the urban perimeter of Londrina, which is located in the North of the state of Paraná. The objectives were the identification of urban species of bats and diurnal roosts used by them and the verification of the problems they can cause to the population. The fire brigade, the Autarquia Municipal do Ambiente de Londrina (Municipal Environment Autarchy of Londrina), the Biology Department of the Universidade Estadual de Londrina (State University of Londrina) and local residents helped spot the roosts. The collections were carried out in regular intervals between April 1998 and March 1999. By the end of them, 815 bats of 23 different species had been captured. Among these, 12 were found near or inside human constructions: Noctilio... |

| An important aspect of the hunting strategy of neotropical social wasps (Hymenoptera: Vespidae) is where they hunt. Three species used two behavioural components in their selection of a place to search for prey. The wasps uti lizcd the odour of freshly damaged leaves as cues (which could be synomones) to select which leaves to inspect and also they remembered a place to which they were strongly attracted to hunt recently and returned there. Polybia ignobilis (Haliday, 1836) and Polistes satan Bequaert, 1940 hunted on a lawn of Digitaria diversinervis Stapf immediately after it was mown in significantly larger numbers than at other times. P. ignobilis and Polistes versicolor (Olivier, 1791) hunted in significantly greater numbers on freshly cut leaves of... |

| The niche breadth of the Portunidae and their overlap on the subtidal sediments of Fortaleza bay, Ubatuba (São Paulo) was analyzed. Samples were made monthly from November/1988 to October/1989, inseven areas of the bay using a shrimp fishery boat equipped with two otter-trawls. Each area was characterized based on environmental factors such as depth, temperature, salinity, dissolved oxygen, organic matter and granulometric composition of the sediment. The number of individuais of each species was registered to each area (resource). Levins's standardized measure (BA) and niche percentage were calculated. Five species of swimming crabs were recorded in this study: Callinectes ornatus Ordway, 1863, Arenaeus cribrarius (Lamarck, 1818), Portunus spinimanus... |

| Two Malaise traps (TOWNES 1972 model) were installed on an island (the "Ilha do Mel") in the Bay of Paranaguá, from September, 1988 to August, 1989. at two sites denominated "Fortaleza" and "Praia Grande", for collection of insects. Apart from collection of insects (Fortaleza: 62.924 individuals; Praia Grande: 38.868 individuais), graphical analysis were limited to those Orders wich occurred concomitantly at the two collection points in ali months: Collembola. Hemiptera. Homoptera. Coleoptera. Lepidoptera. Diptera and Hymenoptera. It was concluded that the Malaise trap is selective for Diptera. Hymenoptera and Lepidoptera. and proved to be efficient in measuring abundance, in obtaining information regarding the seasonal variation of insects, and in... |

| The diet of tadpoles of 13 anuran species was determined to verify whether food resource partitioning occurs and whether the degree of diet similarity is related to taxonomic affinity. Tadpoles of all species studied were mainly herbivorous, except for these of Leptodactylus fuscus (Schneider, 1799) which were mycophagous. Although some species had exclusive items in their diet, most tadpole species ingested the same items, but differed in the amount of each item consumed. Two guilds were found: tadpoles that feed on diatoms on the pond bottom, and tadpoles that feed on Oedogonium Link, 1820 algae in midwater. Diet similarity was related to the taxonomic relationship, microhabitat and feeding behavior of tadpoles indicating that the community organization... |

| On the Brazilian coast, those species nest sympatrically, from the islands of Espírito Santo State to Santa Catarina State. From 1999 to 2002 a sampling program was implanted with the objectives of studying the breeding of S. hirundinacea and S. eurygnatha along Santa Catarina coast. The size of colonies in number of couples, reproduction strategy, length, width, weight and the volume of the eggs, as well as bill length and weight of the nestlings were determined. S. hirundinacea youth weight/length relationship was estimated and the reproductive success of the terns colonies was also determined. |

| O presente estudo foi realizado com o intuito de relatar a ocorrência e morfologia de células pigmentares viscerais constituintes do "sistema pigmentar extracutâneo" em Physalaemus nattereri (Steindachner, 1863) (Leptodactylidae). Foram utilizados dez exemplares machos para a análise macroscópica e obtenção de fragmentos testiculares incluídos em resina e corados com H/E. Os anuros, dentre outros animais exotérmicos, possuem células especiais, os melanócitos, que se caracteriza por intensa pigmentação e sintetiza melanina, além de melanomacrófagos, que se caracteriza por atividade fagocítica e muitas vezes apresentam intensa pigmentação. A nomenclatura destas células não é consensual e, por isso, várias denominações são apresentadas, principalmente nos... |
