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.

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.

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.

Natural cerrado vegetation in São Paulo State now covers less than 7% of its original area and exists only as isolated fragments. Eighty-six sites in these priority cerrado conservation areas were surveyed using a rapid assessment technique. A total of 554 species of vascular plants, belonging to 77 families, was recorded. The vegetation types encountered comprised: campo sujo, campo cerrado, cerrado sensu stricto, cerradão, wet campo, riparian forest, swamp forest, ecotone cerrado/forest and seasonal semi-deciduous forest. Two-Way Indicator Species Analysis (TWINSPAN), Detrended Correspondence Analysis (DCA) and Unweighted Pair-Groups Method using Arithmetic Averages (UPGMA) revealed a weak similarity pattern based on geography, but divided the sites into two main structural groups: (a) areas where more open forms of cerrado occur (cerrado sensu stricto, campo cerrado); (b) areas where only forest physiognomies occur (cerradão, ecotone cerradão/seasonal semi-deciduous forest, or riparian forest). The first group tends to be located in the east and the second in the west of São Paulo State. Cerradão was the most frequent vegetation type, observed in 70% of the sites. Cerrado sensu stricto was recorded in only 31% of the sites. Casearia sylvestris and Byrsonima intermedia were the most widespread species, recorded in 90% and 88% of the sites, respectively. Only 10% of the species were found in 50% or more of the sites, while 19% of species were recorded at a single site only. There was a considerable difference in species number between sites, from a minimum of 29 at Taubaté to a maximum of 185 in one of those at Campos Novos Paulista. As shown in other studies, species richness is directly correlated with diversity of vegetation types occurring at a site (beta diversity). As expected, the seven richest fragments contain ecotonal vegetation, which combines both forest and cerrado elements.

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.

We described and compared the floristic composition, richness, species diversity and structure of the tree-shrub component in pairs of Typical Cerrado (Cerrado Típico) and rocky outcrop Cerrado (Cerrado Rupestre) in two localities in Tocantins State. In each locality, we set up 10 plots of 20 × 50 m at a site, the Cerrado Típico and other Cerrado Rupestre, and sampled the individuals with Db30cm ≥ 5 cm. The rocky outcrop Cerrado did not present any trend towards lower richness and basal area compared to the Cerrado on deep soil. Few species occurred across the four sites and only two important species (Anacardium occidentale and Qualea parviflora) in the four vegetation structure were common to both environments assessed. Furthermore, the occurrence of habitat-specialist species of rocky outcrops and high altitudes (Mimosa claussenii, Tibouchina papyrus, Schwartzia adamantium and Wunderlichia cruelsiana) and the high dissimilarity among sites suggest that altitude is the main responsible for the floristic dissimilarity, followed by the influence of substrate type. Therefore, the information with respect to phytophysiognomy type as a parameter to select areas for conservation, by itself, does not effectively ensure biodiversity preservation, owing to the existing flora heterogeneity not only at local but also at regional scale, revealed by the floristic and structural particularity of each site.

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.

Life On Earth

Soil is the principal habitat and reservoir of fungi that act on ecological processes vital for life on Earth. Understanding soil fungal community structures and the patterns of species distribution is crucial, considering climatic change and the increasing anthropic impacts affecting nature. We evaluated the soil fungal diversity in southeastern Brazil, in a transitional region that harbors patches of distinct biomes and ecoregions. The samples originated from eight habitats, namely: semi-deciduous forest, Brazilian savanna, pasture, coffee and sugarcane plantation, abandoned buildings, owls’ and armadillos’ burrows. Forty-four soil samples collected in two periods were evaluated by metagenomic approaches, focusing on the high-throughput DNA sequencing of the ITS2 rDNA region in the Illumina platform. Normalized difference vegetation index (NDVI) was used for vegetation cover analysis. NDVI values showed a linear relationship with both diversity and richness, reinforcing the importance of a healthy vegetation for the establishment of a diverse and complex fungal community. The owls’ burrows presented a peculiar fungal composition, including high rates of Onygenales, commonly associated with keratinous animal wastes, and Trichosporonales, a group of basidiomycetous yeasts. Levels of organic matter and copper influenced all guild communities analyzed, supporting them as important drivers in shaping the fungal communities’ structures.

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

A New Species

Distinctive, remarkable specimens from Bauru, São Paulo state, Brazil are recognized as a new species of the genus Laemophloeus Dejean (sensu stricto), which is described and illustrated in this paper. Laemophloeus souzalimai sp. nov. is most similar to L. germaini Grouvelle and can be readily distinguished from all New World species of the genus by the dorsal color testaceous, without elytral maculae, antennal club of 6 antennomeres, genal processes anteriorly projected, male head with somewhat pedunculated eyes, and frons with a broad, V-shaped impressed line. Additionally, the preexisting key to Laemophloeus species with antennal club of 6 or more antennomeres is modified to include the new species, and new records for five Brazilian species of the genus are provided.
