Abstract: landscape arrangement plays a key role in community structure and composition. our study was based on the hypothesis that forest fragments work as shelter areas for open-area anuran species. four forest fragments were studied in the municipality of icém, northwestern s?o paulo state; the fragments were 1 to 4 km apart from each other. the anurans were sampled in the fragments by pitfalls, artificial shelters, and active search. twelve species were registered (48% of the species known for the region); three of these species (eupemphix nattereri, leptodactylus podicipinus, and physalaemus cuvieri) had high abundance (n > 50 individuals). in the pitfalls, 228 individuals belonging to 10 anuran species were captured. the high richness and abundance of specimens captured mean that forest fragments are important components for the anuran communities. forest fragments in the icém region can be used by anurans in three non-exclusive ways: i) as shelter areas during the dry season (five species registered); ii) as day shelters during the anuran reproductive season (six species registered in artificial shelters during the day, throughout the rainy season); and iii) as foraging areas (one specimen of leptodactylus podicipinus found feeding on blattaria in the fragment fm2). therefore, the preservation of anuran populations of open habitats depends, to the same extent, on terrestrial habitats, such as forest fragments, and on the ponds where they reproduce.

Abstract: a study on temporal variation in calling site use in a community of anurans was carried out in a permanent pond, between october of 1996 and february of 1998, in southeastern brazil. fourteen species of anurans were registered, belonging to the families: hylidae, leptodactylidae, leiuperidae, and bufonidae. most species in the community were accidental (n = 6) and the majority vocalized in the hot and humid months (october to february). a sucessional pattern in time distribution and a significant statistical correlation between the richness and climatic variables was observed. however, significant statistical correlation between monthly abundance and climatic variables was found only for four species. the analysis of niche breadth, given by the index of levins, indicated that the majority of the species was specialist in the use of the two considered resources. the coefficient of similarity of morisita-horn did not point overlap in time occurrence, but a high overlap in calling site use was detected. multidimensional overlap showed intermediate values between studied dimensions.

Abstract: semi-deciduous forest is one of the most threatened and deforested vegetation types of brazil due to its land conversion to agriculture in the beginning of the 20th century; its distribution is now reduced to less than 8% of its original extent. studies about anuran taxocenosis associated to these forests are scarce, even when we consider the remaining areas of pristine forest. we present herein results from an amphibian survey at the esta??o ecológica dos caetetus, a conservation unit with a singular preserved semi-deciduous forest from the middle-west region of the state of s?o paulo, located inside the priority areas for conservation on s?o paulo state. we provided here data on species richness, composition, geographical distribution, and natural history notes for each taxa found in the area. we recorded 34 anuran species belonging to nine families, of which hylidae and leptodactylidae are the two most speciose families, with 14 and eight species respectively. the high species richness in the area, mainly in the family hylidae, can be explained by both the high environmental heterogeneity of this remnant and its geographic location between cerrado savannas and atlantic rain forest areas. its high species richness when compared with other localities of the same vegetation type, as well as the presence of forest dependent species in the families centrolenidae, hylodidae and craugastoridae, indicate both the good conservation status and the regional importance of this forest remnant.

Abstract: the calling site and the acoustic parameters of the advertisement call were determined for 18 anuran species in six ponds in the northwest region of s?o paulo state. the dominant frequency of the advertisement call was positively correlated with the crc of the species: small size species vocalized in a higher frequency, whereas larger species vocalized in a lower frequency. the similarity in the spectral and temporal parameters of the advertisement call was high among 94% of the recorded species. the similarity on calling site was low; only 22% of species presented high overlap, in spite of about a half of the species have been generalist in calling site use. analysing simultaneously the similarity on calling site, habitat and advertisement call parameters, the proportion of species with high overlap decreased from 94 to 11%, corresponding to the overlap between a single pair of species: dendropsophus elianeae and d. minutus. the species that overlap in calling site presented segregation in acoustic parameters, and those that overlap in acoustic parameters tended to partition the calling site. this result suggests the occurrence of niche complementarity, since species that occupied a similar position in one dimension tended to differ in another dimension. the structural homogeneity of ponds, the climatic severity of the region and the high degree of habitat loss restrict the abundance of population and the species richness of the anuran assemblages. the low overlap on the calling site is probably associated with the insaturation of the sampled communities.

Abstract: this study reports the mite fauna associated with tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. the food habits of the eight remaining species are not known. besides the great richness, the diversity was small, as consequence of the dominance of lorryia formosa cooreman, 1958 and aculus sp., the most abundant species. these species occurred in the same microhabitat but with seasonal segregation: l. formosa was the most abundant in the dry season, while aculus sp. occurred only in the rainy season. in august, when the plant lost its leaves, the following species were found in the apical branch structures: brevipalpus sp. (aff. phoenicis), cheletogenes sp., euseius citrifolius denmark & muma, 1970, lorryia formosa, pronematus sp., and diapause females of tenuipalponychus tabebuiae aguilar, flechtmann & ochoa, 1991. in september, with leaves growing again, aceria sp. was the only species on the plant, and its abundance decreased accentuately in october. the richness and the abundance of the mite fauna were not correlated with the temperature or the precipitation. these data suggest that the plant phenology was more important than the climate in the occurrence of species.

Abstract: Cholelithiasis is a common disease in the general population. One of its risk factors is the type 2diabetes mellitus, related to metabolic abnormalities associated to overweight, obesity, insulin resistance, hypertriglyceridemia and dietary habits.The main risk factors to cholelithiasis aregenetic susceptibility, ileum resection, diabetes mellitus, obesity, hemolytic anemia, age,estrogens and cirrhosis. This study aims to make a correlation between diabetes mellitus and obesity versus prevalence of cholelithiasis in these patients.

Abstract: the structure of the fish communities of a pool and a rapid in the ribeir?o santa bárbara is described. this stream of 5th order is a direct tributary of the rio tietê in the system of the upper rio paraná. thirty three species, from nine families and three orders, were referred in the two mesohabitats: the pool with 31 species, and the rapid with 18. orders characiformes, siluriformes, and perciformes presented the greatest number of species in the two mesohabitats. the families characidae and loricariidae were the most specious, followed by cichlidae in the pool, and by parodontidae in the rapid. most species were accidental, 17 in the pool, and 10 in the rapid, and only six were constant in the two mesohabitats. the greatest diversity and evenness occurred in the pool. the seasonal variation for both assemblages was high, with the pool having a high turnover of species that could be due to the proximity with main channel of the rio tietê.

Abstract: the correct identification of species is a common impediment for studies of conservation, management and environmental licensing. currently, 37 species from five families of anuran amphibians are recorded in the region that includes the turvo-grande, s?o josé dos dourados and parts of the low pardo, low tietê and tietê-batalha hydric resources management unit (ugrhis). despite of being studied since de mid-1960's, none identification key that included all the species recognized was available. although developed for a regional anuranfauna, this key has wide application because the species found in the studied region are associated to open areas and have wide geographical distribution. this study aims to fill this gap presenting an illustrated list about species' biology, and a dichotomous key that comprises 37 anuran species.
