| The aim is to determine the relationship between the diversity of small mammals and the structural heterogeneity and/or secondary successional stages in an Atlantic forest fragment at Viçosa (Minas Gerais). We used Sherman and hook live traps to sample this fauna, monthly from may 1992 to april 1993 in three areas: an abandoned plantation of Melinis minutiflora (campo) and two distinct forest areas (capoeira and mata). The structural heterogeneity was determined as a function of the presence of dead trees, pioneer species, epiphytes, the distances between trees, the tree height and basal area measured by a modified quadrant sample method (Cottam & Curtis 1945). lt was sampled a total of 340 individuals belonging to 17 species. The homogeneous... |

| Grafanthidium. gen.n. is proposed for three new species from northern Brazil, Grafanthidium amazonense, sp.n. from BR 174 km 70 (near Manaus), Amazonas; Grafanthidium rondonicola, sp.n. from Vilhena, Rondônia, and Grafanthidium paraense, sp.n. from Jacareacanga, Pará. The sixth and seventh terga of the males of these new species are characterized by the large carinate lateral lobes, the seventh with the lobes on the apex. Duckeanthidium cibele, sp.n. from Vilhena. Rondônia is described. |

| One hundred and ten specimens of Pseudoplatystoma corruscans (Agassiz, 1829) (Pimelodidae), "pintado", and 582 specimens of Schizodon borelli (Boulenger, 1900) (Anostomidae), "piava", collected in the floodplain of the high Paraná River were analyzed. P. corruscans presented 74.54% of parasitism while S. borelli presented 19.42%. Results of the present research show that in the case of P. corruscans, two species of proteocephalideans presented a significant relationship with the type of environment with regard to prevalence. Spasskyelina spinulifera (Woodland, 1935) was the only species that presented a relationship between the intensity of infection and the environment. In S. borelli only Cucullanus pinnai Travassos. Artigas & Pereira, 1928... |

| The Genus Oryssomus is revised and illustrations of pertinent characters are provided. A key to the genera of Oryssomini and to the species of Oryssomus and Gordonoryssomus are added. Gordonoryssomus. gen.n. is described: type species: Oryssomus deyrollei Crotch, 1874. A new species of Oryssomus, O. unimaculatus, sp.n.. from Amazonas, Brazil and three of Gordonoryssomus, G. nigrus, sp.n.. from Santa Cruz, Bolívia, G. nigripilosus. sp.n., from Espirito Santo, Brazil and G. delicatus, sp.n.. from Rio de Janeiro, Minas Gerais, Santa Catarina and Rio Grande do Sul, Brazil, are described. |

| The natural breeding sites of Toxorhynchites (Lynchiella) haemorrhoidalis haemorihoidalis (Fabricius, 1794), in two study areas, were sampled monthly, during a period of one year, in an upland "terra-firme" forest of the Central Amazon. These natural breeding sites, consisting of water filled palm bracts on the ground, contained invertobrates and vertebrates along with palm inflorescences, leaves and twigs. The inhabitants of the non-submersed area of the bracts include Diplopoda, Acarina, Araneae, Pseudoscorpiones, Isopoda, Blattodea, Coleoptera (Carabidae, Curculionidae, Scolytidae, Staphilinidae). Collembola, Dermaptera, Diptera (Cecidomyidae, Drosophilidae, Mycetophilidae, Tipulidae), Hemiptera, Hymenoptera and Trichoptera. The submersed areas of the... |

| Spalial and temporal density distributions of Amphipoda from the phytals of Caiobá are described. Air temperature oscillated from 16ºC (August and May) to 23ºC (March), surface water temperature from 17ºC (August) to 25ºC (March) and the salinity from 29.3 (May) to 32.8 (August). Two samples of 25cm² (for algae less than 5cm long), 100 cm² (for algae between 5-10cm long) and whole plants (for algae more than 10cm long) were removed with a spatula from the rocky surface at Caiobá Beach, in August/86, November/86, March/87 and May/87. After sorting, the algal substrata were weighted, their adsorption coefficient calculated and the sediment retained among the thallii weighted. The average distance between the branching was measured for all branched algae.... |

| A study on the ecology of Chiroptera was made at the Reserve of Volta Velha on the Northern coast of Santa Catarina. This study aimed at knowing the frequency of the individuals colleeted in each season, part of their feeding diet and their time of activity as well as their breeding activity. The investigation was carried out from March, 1990 to February, 1991 by means of periodical captures which ocurred during four days each month totalizing 144 hours of net use. One hundred and thirty-five individuals belonging to 15 different species were caught. Sturnira lilium (Geoffroy, 1810), Artibeus lituratus (Olfers, 1818) and Myotis nigricans (Schinz, 1821) were captured in the highest number throughout the seasons of the year. Fruit-eating bats confirm their... |
