| It is expected that rare species will be gradually added to biodiversity surveys over time and that complete inventories will include rare species. The objective in the present work is to test whether the capture sequence of species during a bat survey is related to species abundance. Species with capture rates lower than 0.01x10-3 captures/hour-net were considered rare. At Ilha da Gipóia, rare species accounted for 22.22% of the total and, at Rio das Pedras Reserve, they represented 30.00%. The existence of a negative relationship between the relative abundance and the first night of capture of each species for the Ilha da Gipóia and the high significance level for the accumulation curve at both localities suggest that the documentation of a large number... |

| The population biology of Exhippolysmata oplophoroides (Holthuis, 1948) was studied in Ubatuba Bay (23º26'S, 45º02'W), Ubatuba, São Paulo, Brazil, from September/1995 to August/1996. Each sampling comprised eight transects (14 000 m² each), sampled monthly with three repetitions. The specimens were classified with respect to the presence or absence of eggs in the abdominal appendages. Spine-shrimps occurred only on six transects, being most abundant on transect II, with the highest incidence in late spring and throughout the summer months. Ovigerous and non-ovigerous shrimps were present year-round, in an approximately similar proportion (1:1). Site II in Ubatuba Bay is characterized by high salinity and oxygen values, temperature between 26 and 29ºC, low... |

| It was sampled the litter frogs at altitudinal sites of a semideciduous mesophytic forest located at Sena do Japi (Jundiaí, São Paulo, 23º17'S, 47º00'W, 800-1300m altitude, 1500mm rain/year). Forty two plots of 8x8m were sampled in the dry/cold season of 1995: 21 at a Higher Site (HS) (1000m) and 21 at a Lower Site (LS) (850m). The plots were evenly located near, mid-distance, and far from the stream-bed. It was found a total of five species, three at each site. Eleutherodactylus guentheri comprised 83% of the individuals at HS and E. juipoca 67% at LS. The density of individuals was higher at HS and near the stream. The greater density at HS may be due to greater humidity there, provided by mist. The frogs may aggregate in wetter places (stream edges) in... |

| Assessing the composition of an area's bat fauna is typically accomplished by using captures or by monitoring echolocation calls with bat detectors. The two methods may not provide the same data regarding species composition. Mist nets and harp traps may be biased towards sampling low flying species, and bat detectors biased towards detecting high intensity echolocators. A comparison of the bat fauna of Fazenda Intervales, southeastern Brazil, as revealed by mist nets and harp trap captures, checking roosts and by monitoring echolocation calls of flying bats illustrates this point. A total of 17 species of bats was sampled. Fourteen bat species were captured and the echolocation calls of 12 species were recorded, three of them not revealed by mist nets or... |

| The larva of Scinax similis (Cochran, 1952) is described from Ilha do Fundão (Rio de Janeiro, Rio de Janeiro State, Brazil). Comparisons with other species of the group that occur in Southeastern Brazil are added. The larva of S. similis can be distinguished by the following diagnostic features: (1) eyes large in relation to body length (17,3%), body height (26,8%), and body width (29,7%), interocular distance three times larger than eye diameter; (2) lower beak with two transverse stripes, proximal half white and distal half black. |

| In this study the incidence of moths and beetles was examined from feces samples of bats that use different foraging behaviors. Twenty sites around the Fazenda Intervales, a Field Research Station located in São Paulo State, in southeastern Brazil were sampled. Feces were collected from bats caught in mist nets, Turtle Traps or hand nets and, in one case, from beneath a roost. Feces samples were taken from six species of bats: Micronycteris megalotis (Gray, 1842), Mimon bennettii (Gray, 1838), Furipterus horrens (F. Cuvier, 1828), Myotis riparius Handley, 1960, Myotis ruber (E. Geoffroy, 1806) and Histiotus velalus (I. Geoffroy, 1824). To record and describe the frequencies dominating bat echolocation calls, an Anabat II bat detector coupled with an Anabat... |

| A first evaluation of the sedimentary changes, including accumulation of inorganic and organic carbon on the upper slope off Southeastern Brazil under different climatic conditions, based on the analysis of a sedimentary core, is here presented. Results indicate that sedimentation rate as well sedimentary characteristics, including the nature of the organic carbon deposited during the LGM (Last Glacial Maximum), were different from the present deposition, indicating higher primary productivity during the LGM, to be accounted for by the higher values of marine organic carbon. Nevertheless, the higher values of Accumulation Rate of calcium carbonate and organic carbon can be credited to the higher values of the sedimentation rates. Conditions prevailing... |

| Abstract: We recorded a second specimen of the poorly known insular blind snake Liotyphlops caissara. This new specimen expands the morphological variation of the number of dorsal scales in the genus Liotyphlops to 296 (vs. 304 in L. wilderi) and, considering the fact that the holotype of this species was destroyed, the present specimen represents the only available L. caissara individual in zoological collections. Also, this new record constitutes the first out of type locality and expands the distribution of the species in about 40 km to the northeastern. According to IUCN criteria (B1a, b [iii]), we suggest that L. caissara be included in the “Endangered” category, since it occurs in only two insular locations and exhibits an occurrence extension of... |

| We qualitatively studied the gut contents of 20 specimens (36.1-71.3 mm standard length) of the pike cichlid Crenicichla britskii from a 100 m stretched second order stream running inside a small gallery forest in a large pasture area of Rio Aguapeí basin, State of São Paulo, southeastern Brazil. The diet, in terms of per cent composition, constituted primarily of aquatic insects (50%) (mostly immature forms), crustaceans (14.3%), unidentified organic material and filamentous green algae (both with 10.7%), followed by fishes and arachnids (both with 7.1%). Diet analysis indicates that C. britskii is a generalist insectivore with a relatively short digestive tube, which feeds on autochthonous items captured in a broad array of habitats such as in the water... |

| Little is known about the ichthyofauna from South American coastal plain, specially concerning the Mata Atlântica (Atlantic Forest) rivers and streams, as there are regions little explored which may have non-described or rare species. An example is the Parque das Neblinas, a Natural Patrimony Private Reserve (RPPN) in the Bertioga municipality, São Paulo state, where no ichthyofaunal study had been done before. The park's hydrography is made up by the rio Itatinga with its various tributary streams, which flow into the Itapanhaú river basin. Nine sites were sampled using sieves, seines and gill nets; 1,086 specimens of seven species, three orders and five families were captured. The most representative species were Astyanax paranae, Phalloceros... |
