Anurans of a riparian forest in São Carlos, state of São Paulo, Brazil

No presente estudo foi realizado um inventário das espécies de anfíbios anuros que ocorrem em um fragmento de mata ciliar do Córrego do Espraiado, localizado na Universidade Federal de São Carlos (UFSCar), Município de São Carlos, estado de São Paulo, sudeste do Brasil. Durante os meses de março de 2009 a fevereiro de 2010 foram realizadas saídas de campo semanais nas quais foram registradas 13 espécies de anuros. A atividade reprodutiva das espécies de anuros componentes da comunidade estudada mostrou-se sazonal, sendo que houve correlação positiva e significativa entre o número de espécies em atividade reprodutiva e o fotoperíodo. Verificamos que a comunidade estudada mostrou-se mais semelhante a comunidades de anuros de florestas de transição entre Mata Atlântica e Cerrado do que a fragmentos de Cerrado próximos da região.

Fish, Passa Cinco stream, Corumbatai River basin, state of São Paulo, Brazil.

The fishes of the present study were collected in Passa Cinco stream, a main river of Corumbatai river basin, Tiete drainage. Five sites were selected in that stream, downstream from headwater to its mouth, and six samplings were performed using the following fishery equipment: a sieve, electric fishery equipment, gill nets and fish-traps. 5082 individuals, 62 species, 18 families and 6 orders were captured. The orders Characiformes and Siluriformes were the most representative and the families Characidae and Loricariidae presented the largest in number of species.

Fish, Mogi Guacu reservoir and four oxbow lakes, state of São Paulo, Brazil.

The Mogi Guacu River is one of the largest rivers in state of São Paulo, belonging to Parana hydrographic system. A study about fish composition in the Mogi Guacu reservoir and four oxbow lakes downstream the reservoir is showed. A total of 2,367 individuals from six orders, 17 families, and 46 species were collected during August 2005 to July 2006, using gillnets, traps and hand nets. In the reservoir were found 31 species and in the oxbow lakes 24, in which Curimatidae and Characidae were the most abundant families, respectively.

Composition and diversity of bees (Hymenoptera) attracted by Moericke traps in an agricultural area in Rio Claro, state of São Paulo, Brasil

Foram estudadas a composição e diversidade de abelhas em uma área agrícola no município de Rio Claro, Estado de São Paulo, de maio de 2003 a junho de 2004, utilizando armadilha de Moericke. O local de coleta, uma área com 58,08 hectares, caracteriza-se pela produção de grãos e a prática de plantio direto, sendo que 70% da área de entorno é utilizada para o plantio de cana-de-açúcar. Foram coletadas 456 abelhas distribuídas em 20 gêneros, pertencentes às famílias Andrenidae (4,8%), Apidae (40,8%) e Halictidae (54,4%). Espécimes dos gêneros Dialictus (38%) e Diadasia (30%) foram predominantes nesta área. A diversidade de espécies avaliadas pelos índices de Shannon e Simpson foram H =1,88 e 1/D= 4.15, respectivamente, e o índice de Equitatibilidade de 0,61.

Liver dysfunction in patients bitten by Crotalus durissus terrificus (Laurenti, 1768) snakes in Botucatu (State of São Paulo, Brazil)

Os autores estudaram 32 doentes picados por serpentes venenosas, sendo 16 picados por Bothrops spp. e 16 por Crotalus durissus terrificus. Trinta doentes eram do sexo masculino e dois do feminino com idades variando entre 8 e 63 anos (méda 33±15). A prova da retenção da bromosulfaleína apresentou-se aumentada na maioria dos doentes picados por serpentes Crotalus durissus terrificus. Houve correlação positiva entre a retenção da bromosulfaleína e os níveis séricos de alanina aminotransferase e entre alanina e aspartato aminotransferase apenas nos doentes do grupo Crotalus. Um dos doentes evoluiu para o óbito e apresentou no exame anatomopatológico do fígado degeneração hidrópica e lesões mitocondriais. Os autores concluem que as alterações hepáticas são causadas por pelo menos dois mecanismos a saber: lesão mitocondrial por efeito do veneno crotálico; efeito das citoquinas, especialmente a interleucina-6.

Macronutrients transference by litter production in the Morro do diabo forest (Pontal do Paranapanema region, state of Sao Paulo)

The quantities of macronutrients transfer to soil was estimated by the monthly concentrations of mineral elements in the litter produced, over a period of 2 years in the semideciduous forest of Morro do Diabo (Pontal do Paranapanema), in the State of São Paulo (appr. 22-degrees-31'S, 52-degrees-10'W). The transfer of macronutrients to the soil, through litter, was estimated in 426,95 kg.ha-1.yr-1. Nitrogen was the element with the greatest mobilization, with 183,85 kg.ha-1.yr-1 transferred. The sequence of the quantities of macronutrients transferred was: N > Ca > K > Mg > S > P.

Fish, Tatui river basin, state of São Paulo, Brazil.

The Tatui river hydrographic basin locates in low Sorocaba river basin in São Paulo state, Brazil. A relatively high diversity of fish species was noticed at that place, whose habitats are also presumed to be diversified. The Tatui river is an important tributary of Sorocaba river, with great number of smaller streams and marginal lagoons. Fishes were collected using gill-nets, purse seines, sieves and traps, line and hook, every month during one year (from May 2009 to April 2010). Fish species were 51, including seven orders and 18 families. Characiformes and Siluriformes were the most represented with respectively 26 and 14 species.

Distribution and habitat use of Sordellina punctata (Serpentes, Colubridae), with a new record from State of São Paulo, Brazil

Sordellina punctata occurs throughout south and southeastern Brazil in the Atlantic Forest domain (states of São Paulo, Paraná and Santa Catarina). Records from the states of Rio de Janeiro and Mato Grosso do Sul are questionable. A new record from southwestern São Paulo extends its distribution west and northward, probably indicating a wider range in the past. Habitat use in S. punctata implies that it may be more associated with wetlands and other saturated areas than truly aquatics ones.

Bathymetric distribution and recruitment of the spider crab Libinia spinosa H. Milne Edwards 1834 in the Ubatuba and Caraguatatuba regions, northern coast of São Paulo, Brazil (Crustacea, Brachyura, Majoidea, Pisidae)

The objective of this study was to investigate the spatial and temporal distribution of Libinia spinosa H. MILNE EDWARDS 1834 on unconsolidated sublittoral bottoms in two regions off the northern coast of the state of São Paulo, and to analyze the influence of environmental factors on the occurrence of this species and observe the recruitment pattern of its young. Crabs were collected monthly (July 2001 through June 2003) at depths of 5, 10, 15, 20, 25, 30 and 35 In, from a fishing boat equipped with two double-rig nets. Samples of water and sediment were collected for analysis of environmental factors. A total of 2112 spider crabs was obtained (701 juveniles and 1411 adults). The highest abundance was observed at depths of 20 and 25 m, in both regions. These localities were characterized by substrate composed of very fine sand and silt-clay. In regard to the temporal distribution, juveniles and adults predominated in the summer and winter months respectively. From these results, one can infer that the distribution of L. spinosa is related to environmental factors favorable for its life cycle; sediment type is the factor which most strongly determines its presence. © E.

Vascular flora of a cerrado sensu stricto remnant in pratânia, state of São Paulo, southeastern Brazil

The Cerrado (Brazilian savanna) has suffered massive destruction in recent years, mainly due to the expansion of agricultural areas. Many remnants of this vegetation are still poorly studied. Therefore, the purpose of this study was to carry out a floristic survey in a remnant of Cerrado in the municipality of Pratânia, central-west region of state of São Paulo, southeastern Brazil. In total, 120 species (38 families, 88 genera) were registered. The families with greater richness were: Fabaceae (23 species), Asteraceae (15), Myrtaceae (10), Malpighiaceae and Rubiaceae (seven each) and Bignoniaceae (five). The shrub component was predominant in the study area representing 37.5% of the recorded species. A comparison among eight Cerrado areas showed greater similarity between areas with similar altitude. © 2010 Check List and Authors.
