We studied a 1225 ha area, composed mainly of cerrado, in Santa Rita do Passa Quatro, São Paulo State, southeastern Brazil (21°36-38'S, 47°36-39'W). In three cerrado physiognomies (campo cerrado -- a wooded savanna, cerrado sensu stricto -- a woodland, and cerradão -- a tall woodland), we collected all vascular plants in reproductive stage, and identified them to species level. We found 360 species, representing 236 genera and 69 families. The richest families were: Asteraceae, Fabaceae, Poaceae, and Rubiaceae. The savanna physiognomies were richer than the forest one. The ratio between herbaceous and woody species was approximately 2:1. We analysed the whole flora and its two components separately, woody and herbaceous, comparing them with other disjunct cerrado areas. We obtained similarity values (Sørensen index) from 0.47 to 0.81, which showed that the 3 diversity of the cerrado was higher in the herbaceous component than in the woody one.

This study aims to characterize and compare three Cerrado areas (one cerradão and two cerrado sensu stricto areas) in Patrânia, São Paulo state, southeastern Brazil, concerning the floristic composition. In total, 250 taxa were found belonging to four species of pteridophytes, one species of an exotic gymnosperm and 243 species of angiosperms. Differences in species number and proportion of the woody and herbaceous components were observed among the three Cerrado areas. The similarity analysis revealed that the cerradão seems quite peculiar, showing low similarity level with the cerrado sensu stricto areas contiguous to it, being more similar to other cerradão areas located in nearby municipalities.

Based on studies of floristic lists the contribution of forest tree and shrub species in a forested savanna area in the city of Bauru, State of São Paulo, and in 14 different places sheltering cerrado sensu stricto and cerradão in Brazil is defined as the evidence of forest species causing a change of cerrado heterogeneity. The percentages of occurrence of forest species in the locations analyzed varied from zero to 4.5%. The proximity of different forest matrices, the occurrence of fires and the inclusion criteria used were some of the factors that may have influenced such variation.

Geographical Position

The aims of the present work were to carry out a floristic-structural study of the shrubby-arboreal component of a savanna fragment (cerrado sensu stricto) in São Paulo State, Southeastern Brazil, and to compare with other areas. Twenty one plots of 250 m² each were delimited and plants with stem basal diameter equal or superior to 3 cm were included in the sampling. The recorded individuals corresponded to 3,062 and 58 species belonging to 34 families were registered. Asteraceae had the largest number of species (seven), followed by Fabaceae and Myrtaceae (five each). The most important species were Tibouchina stenocarpa and Anadenanthera falcata. The floristic composition of the study area indicates that it might be considered a transition from cerrado to seasonal semi-deciduous forest. The comparison with other surveys indicates floristic-structural heterogeneity of these cerrado areas and the multivariate analysis showed that areas grouped according to their geographical position and soil type.

A natural vegetation area, with 1269 ha, composed mainly by cerrado, located at Santa Rita do Passa Quatro Municipality, São Paulo State, southeastern Brazil (21°36-39'S, 47°36-38'W), was studied. From September 1995 to February 1997, a floristic survey was carried out, when all vascular plant species at reproductive stage were collected. The flowering and fruiting patterns of the community were studied, comparing the herbaceous and the woody species. In the herbaceous component, 239 species were found and, in the woody one, 108 species. The woody species flowered mainly at the beginning of the rainy season, while the herbaceous ones produced flowers generally at the end of that season. The proportion of anemo and autochorous species was greater in the herbaceous component. The zoochorous ones, on the contrary, were more frequent in the woody component. At the dry season, when their dispersion is more efficient, the proportion of anemo and autochorous species producing fruits was higher. During the rainy season, when their fruits become attractive for longer time, the zoochorous species fruited more intensely.

The floristic composition in a freshwater swamp forest remnant located in the municipality of Botucatu, São Paulo state, Brazil, was studied. Only Angiosperms were collected in the area by means of random walks. A total of 92 species were registered. The families with greater species richness were: Orchidaceae (17 species), Rubiaceae (8) and Myrtaceae (5). The arboreal component was predominant. The profile diagram of the vegetation showed a well-defined stratification, with a continuous canopy and an inferior tree layer composed mainly by individuals of Euterpe edulis Mart.. A comparison among the angiosperms of the study area and those of ten swamp forests in São Paulo state suggests that the geographic position and other ecologic peculiarities of these forests, besides soil flooding, are factors that can influence their similarity concerning the floristic composition.

The clinical and laboratory data of a disease in a resident of Ribeira Valley, São Paulo State, southeastern Brazil, caused by an agent close or identical to Caraparu, a Group C arbovirus, was described. Although there is evidence of an intensive circulation of several arboviruses in the area, no diagnosis of human disease by these agents has been made, except the encephalitis cases caused by Rocio virus during an epidemic in 1975-1977. An antigenic difference between Caraparu strains isolated in São Paulo and in Pará States and a close antigenic relationship between Caraparu strain from São Paulo and Bruconha virus were suggested by the serological tests.

We used Raunkiaer's system to classify in life-forms the vascular plants present in 12 random 25 m² quadrats of a cerrado site. The study area is covered by cerrado sensu stricto and is located in the Valério fragment, at about 22º13'S and 47º51'W, 760 m above sea level, in the Itirapina Ecological and Experimental Station, São Paulo State, southeastern Brazil. The floristic spectrum considers the life-form of each species, while in the frequency spectrum, each species is weighted by its frequency. The vegetation spectrum does not consider the species at all, but only the individuals in each life-form class. In the floristic spectrum, the most represented life-forms were the phanerophytes and the hemicryptophytes, as in other cerrado sites. This spectrum differed significantly from Raunkiaer's normal spectrum, mainly due to under-representation of therophytes and over-representation of phanerophytes. The floristic and frequency spectra were similar, but both differed from the vegetation spectrum. We recommend the floristic spectrum when working at larger scales and a description of the phytoclimate is wanted. The vegetation spectrum is preferable when working at smaller scales and wanting a quantitative description of the physiognomy. The frequency spectrum is not recommended at all.

The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in the country. However, despite the large number of studies in this area, there are still many sampling gaps within biomes such as the Atlantic Forest that are considered global conservation priorities due to the high rate of endemism and human disturbance. As a result of political and historical pressure, this biome has been reduced to less than 12% of its original extent and, despite its importance for global biodiversity conservation, only a small percentage of its original vegetation cover (1%) has some form of legal protection. This is the case of the Parque Estadual Turístico do Alto Ribeira (PETAR) which, together with the Parque Estadual de Intervales, Parque Estadual Carlos Botelho and Mosaico de Unidades de Conservação de Jacupiranga, forms of an ombrophilous forest continuum of 360 thousand ha in the south of São Paulo State. This study presents a list of amphibians and reptiles from the PETAR, with information on the local distribution and habitat use of the species. The survey was conducted from October to December 2009, completing a total of 15 sampling days using four complementary methods of active sampling: visual encounters, auditory encounters, searches by car and incidental encounters. We recorded a total of 91 species belonging to 53 genera and 24 families. This high diversity can be attributed to the existence of a wide variety of habitats and microhabitats in this region, such as the various aquatic sites used by many species of anuran amphibians. Moreover, the PETAR features a large altitudinal gradient (80 - 1,160 m elevation) that gives a large climatic, geological and hydrological heterogeneity to the area. This inventory is an important contribution to the expansion of knowledge about these assemblages in the Atlantic Forest to the south of Serra de Paranapiacaba mountain range, and provides support for the conservation of these groups in São Paulo State.

Helicometrina nimia (Opecoelidae) is a digenean with wide distribution. Fish families most commonly used as hosts for H. nimia are Serranidae, Pomodasydae, Scorpaenidae and Clinidae. In the present study, a new host and a new host locality are presented for the species. A description of the studied specimens, besides comments concerning its taxonomic status and biometrically compared tables of H. nimia reports are given. The taxonomic status of members of Helicometrina has been questionable. The greatest controversy for the genus seems to be related to the validity of diagnostic features, especially in regard to the number of testes. In the present study, all studied specimens presented a permanent and steady number of testes (n=9) and therefore its use as a diagnostic character is supported by the present authors. Epinephelus marginatus is considered a new host for Helicometrina nimia, and São Paulo state, southeastern Brazil, a new locality for the species.
