| Com base no exame dos tipos, são redescritas as espécies Vaginula andreana Semper, 1885, Vaginula reinhardti Semper, 1885 e Vaginula trilineata Semper, 1885. As espécies provêm, respectivamente, de Maurício (Ilhas Mascarenhas; leg. Andrea), Macau, China (leg. Reinhardt), e provavelmente Maurício (Ilhas Mascarenhas; leg. Andrea, encontrado num pote de plantas no Jardim Botânico de Copenhague). Discute-se a sinonímia das espécies. |

| Inspite of Etythrina species exhibit morphologic attributes for adaptation to pollination by nectarivorous birds mentioned in the literature, E. speciosa is pollinated by lots of bees (Apinae and Meliponinae) which show a great urban occurrence. Systems of E. speciosa floral reproduction, fenology, diversity, frequency and constancy of insects visiting at different hours and flowering periods were studied. E. speciosa is Biocompatible, but xenogamy is the predominant system of reproduction. A large diversity of insects visiting the inflorescences was observed, with predominance of bees. The bee species showed a higher frequency: Apis mellifera Linnaeus, 1758 (45,0 %), Trigona spinipes (Fabricius, 1793) (28,6%), Trigona hyalinata (Lepeletier, 1836) (12,2 %)... |

| Studies were carried out with Lagerstroemia speciosa Pers. on floral reproductive systems, diversity and constancy of visiting insects at different hours of day, the behaviour of these insects at the flowers and the influence of these environmental factors in relation to their visits. The fenology, anthesis and others particularity of this vegetal species was studied. A great diversity of insects was verified visiting the flowers with the predominance of bees. The most frequent and constant species encountered were: Nannotrigona testaceicornis (Lepeletier, 1836) (40,2%), Tetragonisca angustula (Latreille, 1811) (16,9%), Apis mellifera Linnaeus, 1758 (11,8%), Plebeia droryana (Friese, 1900) (9,1 %) e Exomalopsis fulvofasciata (Smith, 1879) (8,5%).

| Durante o período de 1976-1983, fluxos migratórios de duas espécies de Pieridae foram observados em Brasília, D.F. Esses vôos apresentaram periodicidade anual e direção constante. Na primavera, grandes concentrações de Phoebis (Aphrissa) statira voavam para sudeste, contra o vento. Durante o verão, Anteos clorinde foi observada voando contra o vento em direção oposta (SW). Essas migrações são provavelmente relacionadas a gradientes longitudinais da fenologia das plantas hospedeiras. |

| Zelleriella ubatubensis, sp. n. is described. This species was found in the caecal region of the leptodactylid Thoropa miliaris from Ubatuba, SP, Brasil. The cell body has an irregular ellipsoid outline (145.9 µm ± 3.0 x 93.9 µm ± 24). The nucleus (16.7 µm ±0.3) has a fragmented nucleolar mass (more than nine nucleoli). Z. ubatubensis seems to be morphologically similar to Z. caryosoma and Z. foliacea but it differs from them by dimension, chromatin and host. A great number of the observed specimens contained Endamoeba paulista in their cytoplasm. |

| Ovigerous females of Pachygrapsus transversus (Gibbes, 1850) were collected on the Praia Dura and Saco da Ribeira beaches, Ubatuba, São Paulo, Brazil. Larvae were individually reared in a climatic room at 25ºC temperature, salinities of 28, 32 and 35‰ and under natural photoperiod conditions. The best rearing results were observed at 35%o salinity. Seven zoeal instars were observed, drawing and described in detail. The data are compared with those obtained for P. gracilis (Saussure, 1858). |

| O presente estudo pretende comparar a distribuição vertical da comunidade bêntica na zona entremarés em dois locais compostos por matacões graníticos caracterizados por hidrodinâmica distinta, reflexo da diferença na orientação dos molhes nas praias do Farol de São Tomé (Píer) e na Barra do Furado (Barra), norte do Estado do Rio de Janeiro. Quadrados de 400 cm² foram sobrepostos ao longo de três perfis verticais de ambos os sítios e amostrados através do método de fotoquadrats, desde o nível 0,2 m da maré até o limite superior de Littorina spp. O limite superior dos organismos marinhos foi ampliado na Barra (3,8 m) em relação ao Píer (2,2 m). Quanto à composição taxonômica, nove espécies foram comuns. Chaetomorpha sp., Chondracanthus teedii (Mertens ex... |

| Proper site selection is fundamental in the success of any aquiculture enterprise. To identify suitable areas for freshwater prawn culture in Pernambuco, factors like elevation, relief, soil and climate were considered, in accordance with the species biology and pond construction. According to the established criteria, suitable, unsuitable and unfavorable areas, with some restrictions, were recognized. Suitable areas for freshwater prawn culture in Pernambuco are about 835 km², representing 0.85% of the total area of the State. |

| This study analyzes the use of aquatic mammals by prehistoric societies of Santa Catarina Island, Southern Brazil. Samples from two archaeological sites were examined: Rio do Meio (RM) and Porto do Rio Vermelho (SCPRV). Nine aquatic mammal species were found: a) pinnipeds: Arctocephalus australis (Zimmerman, 1783) and A. tropicalis (Gray, 1872), and b) cetaceans: Eubalaena australis (Desmoulins, 1822), Delphinus delphis Linnaeus, 1758, Stenella frontalis (Cuvier, 1829), Steno bredanensis (Lesson, 1828), Tursiops truncatus (Montagu, 1821), Pontoporia blainvillei (Gervais & d'Orbigny, 1844) and a non-identified rorqual from the genus Balaenoptera Lacépède, 1804. Three especies of semi-aquatic mammals were also recorded: Hydrochoerus hydrochaeris... |
