| Three species of Chrysomya were collected and the most frequent were: C. albiceps (Wiedemann, 1819) (62,62%), C. putoria (Wiedeman, 1818) (30,11%) and C. megacephala (Fabricius, 1794) (7,27%). The peaks of the populations of these species occurred in November and December/1988 and October and November/1989, and the small frequencies occurred from April to June/1989. All species showed significant correlation to 5% level with pluviometric precipitation, and none species showed correlation with temperature and relative humidity. |

| Two Malaise traps (TOWNES' 1972 model) were installed on an island (lhe "Ilha do Mel") in lhe Bay of Paranaguá, from September, 1988 to August. 1989. at two sites denominated "Fortaleza" and "Praia Grande", for colleetion of insects. At "Fortaleza". 1,715 individuais of Tabanidae were captured, representing 3.20% of all Diptera captured in this site, while at "Praia Grande" 1,420 individuais of the same family were captured, representing 5,06% of ali Diptera captured there. In "Fortaleza", Tabanidae is represented for 10 species, while in "Praia Grande" it is represented for nine species.

| Micoureus demerarae (Thomas, 1905) is a medium-sized marsupial, around 130 g, with a nocturnal habit and insectivorous-omnivorous diet. From August 2001 to July 2002, seven individuals, three males and four females, were monitored with radio-telemetry in Reserva Biológica União, state of Rio de Janeiro, Brazil, aiming to investigate and describe the sleeping sites used by this marsupial. Fifty eight sleeping sites were located, most of which (70,7%) in palm trees Astrocaryum aculeatissimum (Schott) Burret, and the remaining in other tree species (29,3%), a significant difference (chi2 test; p < 0.005). The preference for this palm tree was not different between sexes (chi2 test; p = 0.920). It was possible to locate the exact place where the animal was... |

| The influence of a diet based on putrid horse meat over the post-embryonic development of Cochliomyia macellaria (Fabricius, 1775) under controlled conditions (UR 65 10% and 14 hours of photophase) was compared with the results obtained using a meat broth diet to which other sources of animal and vegetable protein were added. The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the... |

| A new species of synaptid holothurian, Leptosynapta brasiliensis n. sp., is described. The species shows affinities with Leptosynapta minuta (BECHER, 1906), presenting 12 simple tentacles and 12 dumb-bell shaped pieces constituting the calcareous ring; anchor ossicles exhibit a sharply bifurcate stock. All individuals were collected in Praia Vermelha, Rio de Janeiro - RJ, Brazil, in coarse sand, at a depth of some 3 m. |

| This communication deals with the sexual colour patterns in the sandperch Pseudopercis numida Ribeiro, 1903, a benthonic fish of commercial importance, endemic to the Brazilian continental shelf, occurring off the coasts from Espírito Santo to Rio Grande do Sul States. The males have the head, the dorsal part of the body, and the pectoral and caudal fins blackishes, whereas the females have them brown-yellowishes. Such patterns are constant characters, not related to maturity or breeding seasons. |

| The silverside, Atherinella brasiliensis (Quoy & Gaimard, 1824), a resident species of the shallows of bays, estuaries and coastal lagoons, was studied during two annual cycles, using beach seines (July 1996 to June 1998), in the continental margin of the Sepetiba Bay, aiming to assess recruitment and distribution patterns. A wide recruitment period, with young-of-the-year appearing from early spring to early autumn, was shown, with peaks of juveniles (Total Length-LT = 10-30 mm) being recorded in two periods of the year; one in November and another in March. The highest abundances, of both juvenile and adults, were recorded in Coroa Grande and Itacuruçá, sites located in the outer Bay, during the whole summer, with significant differences were... |

| Reproductive biology and feeding of Curimatella lepidura (Eigenmann & Eigenmann, 1889) were studied in Juramento reservoir, São Francisco River basin, Southeastern Brazil. Histological analyses and gonadosomatic indexes revealed females and males in reproductive activity from October to March and total spawning occurring from January to March coupled with the peak of spermiating males. In the dry season, the fishes accumulated energetic reserves for reproduction during a short rainy season. The species presented sexual dimorphism, being females larger than males and sexual maturation occurring close to 7.7 cm standard length for females and 7.1 cm for males. C. lepidura presented iliophagous feeding habit, ingesting mainly sediment/detritus and a... |

| Gametogenic and histochemical aspects of an edible bivalve, lphigenia brasiliana (Lamarek, 1818) from Itaipu Lagoon, Niterói, State of Rio de Janeiro, were studied. Between May 1998 and October 1999 a total of 120 clams were picked up. Samples of 10 animals were collected once a month. Specimens were fixed in Bouin's fixative for 4 hours or less and transferred to 10% formalin for 24 hours. The shell lenght has been measured with the valves lightly opened to permit the penetration of fixative solution deeply in the tissues. Transverse sections including digestive diverticula, mantle, gills, gonad and foot were obtained from the total body. After fixative treatment, tissues sections were embedded in paraffin, cut routinely at 5 µm and stained with Harris's... |

| Chrysemys dorbigni is a common diurnal turtle in the Taim Ecological Station. Though females may choose nesting sites in the same area they do it isolately, not in groups. Data on female nesting site selection, building of nest and egg laying are given. Under laboratory and field conditions development was followed from the egg stage to the emergence of hatchlings and growth of juveniles. One to 16 eggs are laid per clutch. Nesting activity is coincident with periods of higher temperatures in the field. Abiotic conditions and incidence of predation have been considered to estimate the success of clutches. |
