| Patterns of spatial occupation, feeding, and reproductive period of two species, Corydoras aeneus and Corydoras gr. carlae (Siluroidei, Callichthyidae), coexistents in the Alambari River (Botucatu, São Paulo), were studied. High diet overlap, partial spatial segregation, and well differentiated reproductive strategies were verified. These findings do not permit to evidence the occurrence of competitive interactions between the analysed species. |

| Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred... |

| From 1986 to 1992, I surveyed the invertebrate fauna of twelve limestone caves from South Ribeira Valley (State of Paraná, Brazil). Associated to walls in the entrace zone live Enoploctenus and Blechroscelis spiders, Goniosoma opilionids, Strinalia crickets, Latebraria amphipyroides moths, and Culicidae and Sciaridae dipterans. In aphotic zone, occur Plato spiders, Daguerreia inermis opilionids, Pseudonannolene strinatii diplopods, Smicridea caddisflies and the aquatic crustacean Aegla paulensis. I found in both zones Ctenus fasciatus spiders. Paronella collembolans, Zelurus travassosi heteropterans, Cholevidae and Anthribidae beetles, Phoridae dipterans and Braconidae wasps. One of the most important energy sources in these caves is the hematophagous bat... |

| 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... |

| Pinnixa gracilipes Coelho, 1997 is a small pinnotherid crab living in association with ghost shrimp Lepidophthalmus siriboia Felder & Rodrigues, 1993 in the northeastern region of Pará State, Brazil. Larvae of P. gracilipes were reared in the laboratory from hatching to the megalopa stage. The complete zoeal period averaged 24 days. Mean duration for each larval stage was 5, 4, 4, 5 and 6 days, respectively. In the present study, five zoeal and megalopal stages are described and illustrated in detail. Morphological comparisons with previous reported works on Pinnotheridae larvae are briefly discussed. |

| Foregut in D. hominis (Linnaeus Jr., 1781) as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the... |

| Population structure of the porcelain crab Petrolisthes armatus (Gibbes, 1850) from the rocky shore of the Farol isle (25º51'S, 48º32'W) was carried out in the following aspects: annual fluctuation of the density, distribution of the developmental stages and sexes over year round, size composition and recruiting period of juveniles into the population. Monthly collections were made in the three sites of the midlittoral, from November/89 to April/91, with the aid of a trap. The air temperature ranged from 13ºC to 28ºC, that of the surface water from 16ºC lo 29ºC and the salinity of the surface water from 06.7 to 31.5. A total of 5.585 individuals of Petrolisthes armatus was collected, among which, 116 were in the megalopa stage, 1,579 juveniles, 830... |
