Diversity of the ichthyofauna in the Serra do Mar State Park- Núcleo Santa Virgínia, Sáo Paulo State, Brazil

The aim of this work was to assess and compare the diversity of the ichthyofauna in three headwater rivers of Paraíba-do-Sul basin in the Serra do Mar State Park, Núcleo Santa Virgínia. A total of 1,774 specimens of 16 species of fishes belonging to 6 families were caught. Characiforms were the most abundant fish at all three sites, followed by Cyprinodontiformes, Siluriformes, and Perciformes. The Shannon index (H′), evenness (E), and the Jaccard and Morisita-Horn similarity indexes were low, indicating both low diversity and low similarity of species among the three streams. The values of these indexes should be evaluated according to the biotic and abiotic conditions in each environment. It is clear that in mountain streams of the Atlantic Forest, these low values occur because of the presence of a few abundant and many rare species.

Discopyge castelloi sp. nov. (Torpediniformes, Narcinidae), una nueva especie de raya eléctrica del Mar Argentino

A new species of electric ray of the family Narcinidae, Discopyge castelloi, is described from the southwestern Atlantic off Argentina. Distinctive characters of the new species are the form of the body, the posterior position of pelvic fins and the manner as pelvic fins join the caudal peduncle, the morphology of the nasal curtain and the presence of small but apparently functional eyes. Discopyge castelloi is the fourth torpediniform species reported from the area. It appears to be very rare on the shelf, though the type locality is separated from that of the paratypes by seven latitude degrees. As in the case of Torpedo puelcha, it is probable that the new species has a normal habitat deeper than that of the available specimens.

Dinâmica da paisagem do município de Cubatão: Crescimento entre portos, indústrias e a Serra do Mar

With more than 60% of its territory under environmental protection, the city of Cubatão shelters the Industrial Pole and is located midway of two great metropolitan regions of State of São Paulo: Grande São Paulo and Baixada Santista. Both the implantation of industries and the construction of highways stimulated a process of migration and irregular occupation of the territory, with significant loss of the original vegetal covering of Atlantic Forest, in addition to pollution of water resources and the soil. The present work analyzed the dynamics of the landscape of a stretch of the city of Cubatão, associated to the Highway System Anchietas-Imigrantes, on the basis of economic cycles and regional public policies, aiming at helping the urban and environmental planning of coastal cities. We used a temporal series of air photographs of five decades and bibliographical surveys on the description of the region occupation. A non planned urban expansion for the city was evidenced, closely related with regional economic cycles and road building, directed to areas adjacent to highways and railroads, marshland and flooded plains landfills and mounts hillsides, including areas near Serra do Mar State Park. One suggests that the questions of environmental and urban planning of coastal cities are dealt with in the regional domain and in a participative way on the basis of studies of economic expansion and tourist activities in Baixada Santista, guaranteeing the maintenance of the remainders of Atlantic Forest in São Paulo coast.
