Biological aspects of Schizodon nasutus Kner, 1858 (Characiformes, Anostomidae) in the low Sorocaba river basin, São Paulo state, Brazil

Four biological aspects of Schizodon nasutus in the low Sorocaba river basin, São Paulo, Brazil were analysed. These were accomplished during the year seasons. The fish diet and the feeding activity were investigated by studying the repletion index, which showed no significant differences between seasons. The food items analysed by frequency of occurrence and dominance showed a predominance of vegetable items in the diet. The reproduction, analysed by using the gonadosomatic index, indicated that the reproductive period occurs during the summer period when temperatures are higher and rainfalls are more intense. The amount of accumulated fat and condition factor varied according to reproduction, especially for females.

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.

Phlebotomine (Diptera: Psychodidae) survey and some considerations about epidemiological aspects of canine leishmaniasis in Rio Claro city, São Paulo, Brazil.

Between 2000 and 2004, 170 sand flies were captured in urban or peri-urban areas of the Rio Claro city, SP, Brazil. Nyssomyia neivai, the main LTA vector species in São Paulo territory, corresponded to 124 specimens (72,94%) of the total number of captured insects. Incidence of American Cutaneous (LTA) and Visceral leishmaniasis (LVA) is increasing in human and dogs in São Paulo State. Rio Claro city is located in the center-east region of the State. During 2001 and 2003, two cases of alochtonus canine LVA and an autochthonous case of canine LTA were locally diagnosed. Results indicate the risk of LVA establishment in this region. Possible role of alternative vectors in leishmaniasis transmission is discussed.

Birds of a central São Paulo woodlot: 1. Censuses 1982-2000

Foram listadas 263 aves próximo e dentro de uma mata semidecídua de 230 ha em meio a plantações de cana-de-açúcar, na região central do Estado de São Paulo, Brasil. Subtraindo-se 67 espécies de áreas abertas, 22 de riachos, 10 vagantes e 12 observadas mais tarde, cerca de 152 espécies de mata e de borda foram observadas entre 1982-86, semelhantemente às observadas em uma mata próxima a Campinas. Ambas as matas perderam espécies gradualmente. Algumas aves evitaram as margens duras dos canaviais, preferindo as margens macias arbustivas. Das espécies de área aberta, parece que 22 desapareceram até 1997, em razão das abundantes chuvas anteriores causadas por El Niño, ou pela raridade de habitats permanentemente abertos nos canaviais; 17 espécies novas eram principalmente noturnas que não haviam sido checadas anteriormente, ou visitantes ocasionais. A mata e as bordas perderam 37 espécies, ganhando 5 de regiões secas e 1 visitante de inverno. Vários migrantes do sul apareceram somente em anos chuvosos antes do recente efeito estufa; algumas aves residentes foram caçadas, e os beija-flores das copas talvez estivessem presentes ainda. As espécies de zonas secas, prones à movimentação ou metapopulacionais, movem os centros de distribuição, camuflando parcialmente a perda de diversidade da mata úmida.

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.
