Mapeamento, erodibilidade e tolerância de perdas de solo na sub-bacia do Ribeirão das Perobas

The land use conservation planning requires knowledge of the soil characteristics, natural susceptibility to erosion and the soil loss limit. In this context, the objectives of this study were to perform a detailed soil survey of Ribeirão das Perobas watershed, located in Santa Cruz do Rio Pardo, São Paulo State and to determine and map the erodibility and soil loss tolerance of the soil classes found in the survey. The following techniques were used to perform the detailed soil survey: photopedology, field sampling, physical analysis, chemical analysis, and morphological description of the soil samples and profiles. The erodibility was determined by the methods described by Denardin (1990) and Mannigel et al. (2002), and the determination of soil loss tolerance followed the methodology of Mannigel et al. (2002). The results of erodibility determined by the methodology of Denardin (1990) were not discrepant and they did not distinguish soils that are known to have different susceptibility to erosion., w\Whereas, using the methodology of Mannigel et al. (2002), very high or very low erodibility values were observed in soils with extreme contents of sand silt or clay. The most influent variable to the soil loss tolerance results was the correction factor for the textural gradient of clay between soil horizons.

Redescription of Parotocinclus bahiensis (Miranda-Ribeiro, 1918) (Pisces, Ostariophysi, Loricariidae)

Microlepidogaster bahiensis Miranda-Ribeiro (1918), assigned to Parotocinclus Eigenmann & Eigenmann, 1889, by Garavello (1977), was described in a short and uninformative way which does not allow for its distinction from other species of Parotocinclus; besides, the two syntypes of the species are regarded as lost. For these reasons a neotype is herein designated and a detailed description of the species is presented based on topotypes. The species is characterized by the combination of the following features: scapular bridge almost completely exposed ventrally, arrector fossae, when present, small or very reduced; abdomen covered by 5-7 wide lateral plates on each side and very small platelets in between, leaving abundant naked areas surrounding them; a small group of larger plates in front of anus; caudal peduncle ellipsoid in cross section; total plates in median series 21-23; longitudinal series with 23-26 plates; 18-29 teeth on premaxillary and 12-24 on dentary; it can also be distinguished by its characteristic caudal-fin color pattern. Features that allow us to assign the species to Parotocinclus and a hypothesis about its relationships with other species of the genus are also presented.
