Othonella araguaiana (Bivalvia, Megadesmidae) from the Corumbatai Formation (Midlle [Middle] Permian), Eastern Margin of the Parana Basin: systematic, evolutionary and biostratigraphic significances.

In this study, the occurrence of Othonella araguaiana Mendes, a rare bivalve species is reported for the first time in the Pinzonella illusa biozone, Middle Permian Corumbatai Formation, in the State of São Paulo. This species was originally described in coeval rocks of the Estrada Nova Formation (= Corumbatai) from the Alto Araguaia and Alto Garcas regions, State of Mato Grosso. The specimens of O. araguaiana were found in the base of a bioclastic sandstone bed, a proximal tempestite, in the middle of the Corumbatai Formation, in the city of Rio Claro, São Paulo State. The silicified shells and internal molds are well preserved, showing impressions of muscle scars and other internal anatomic characters (e.g., hinge), never illustrated by previous authors. In his original description, Mendes (1963) called attention to the similarity between O. araguaiana and Terraia aequilateralis, a common veneroid of the Corumbatai Formation. Conversely, Runnegar and Newell (1971) suggested that O. araguaiana belongs to Megadesmidae, being a junior synonym of Plesiocyprinella carinata (the commonest megadesmid of the Passa Dois Group). Our study indicates that O. araguaiana is indeed a megadesmid, but is distinct from the P. carinata. The new occurrence of O. araguaiana demonstrates that a) the paleobiogeographic distribution of this species is wider than previously thought (that it was restricted to the northern part of Parana Basin, Mato Grosso State); b) the molluscan fauna of the Corumbatai Formation (P. illusa biozone) in the State of São Paulo is more diverse and dominated by megadesmids; and c) the composition of the molluscan fauna of the Corumbatai Formation in Alto GarYas, State of Mato Grosso, is essentially the same as that of the P. illusa biozone of the eastern margin of the Parana Basin.

Aspectos lithoestratigraficos da Formacao Uberaba, Cretaceo da Bacia do Parana.

The Uberaba Sandstone formation with local expression in the city of Uberaba (State of Minas Gerais) and vicinities, has been focused from different lithostratigraphic points of view. In spite of its characterization by previous authors as a formation, its geographic distribution as well as its relationship with other units of the Parana sedimentary basin has never been adequately elucidated. Simultaneously with a better characterization of the Uberaba Formation petrographic properties, the authors redefine its geographic distribution and suggest a possible stratigraphic relationship with other formations of the Bauru Group which have been defined in the State of Sao Paulo.-English summary

Influencia do soerguimento do alto Paranaiba na sedimentacao pos- basaltica na area do Triangulo Mineiro (MG), borda NNE da Bacia do Parana

Faciologic analysis method was applied to after-basaltic sedimentary deposits in Triangulo Mineiro (MG) area. Faciologic association 1 (Adamantina formation) and unities 1 to 5 (Uberaba formation) are related to the fluvial and lake deposits: faciologic association 3 (Ponte Alta Member) and 2 (Sierra da Galga Member) represent the sedimentary deposits associated to the alluvial fans conditions. With faciologic association and unities it could be to recognize the paleogeografic and tectonic conditions in sedimentation time of that depositional tract. -English summary

Razao Sr:Ba:Rb e tipologia de zircao em granitoides dos Estado de Sao Paulo, Parana e Minas Gerais

Chemical (Sr:Ba:Rb) and zircon typology data from the Nazare Paulista, Mairipora/Cantareira, Cunhaporanga, Tres Corregos, Morungaba, Socorro, Itu, Graciosa and Serra Carambei granitoid complexes from the states of Minas Gerais, Sao Paulo and Parana (SE/S Brazil) are presented and discussed. By the zircon typology method these complexes are refered, respectively, to the 2nd crustal, 3rd crustal/low temperature C-A, low temperature C-A, medium temperature C-A, medium/light temperature C-A, K-SA/Alkaline and alkaline series which are considered as generated under increasing temperature associated with a progressive major participation of mantle material. All these series display different positions and behaviour in the Sr:Ba:Rb diagram which reinforces the use of the zircon typology method in the study of granitoids. -from English summary

Sprawling and Urban transportation system: Impacts in the city of Londrina, Parana, Brazil

After nearly 80 years since the construction of its core, represented today by the city's central area, Londrina, located in the state of Parana, has the appearance of a new city but its features and trends of planning policies depict the bad examples of Brazilian cities. With a booming urban growth, from north to south of the county, the urban interstices represented by big voids in the middle of the city created speculation and the concept of an ideal city slowly disappeared. With a metropolitan appearance and, at the same time, with small town aspects, Londrina stands out as an automobile-oriented city, a fact that has impacted the livelihood of the population, generating environmental impacts for all social classes. This paper discusses how the form of occupation in Londrina, characterized by the sprawl phenomenon and its relation to car preference as a mode of transportation has generated urban environmental impacts. It was concluded that the choice of using cars in Londrina, as well in other medium-sized Brazilian cities studied by the comparative method, has increased and has generated bottlenecks in traffic. As a consequence, there is a constant expropriation of properties for widening roads and at the same time, the presence of various densities and urban voids that form an uneven urban space and an obstacle to efficient urban planning. © 2012 WIT Press.

Incidence of canine leptospirosis in the metropolitan area of Curitiba, State of Parana, Southern Brazil

Introduction The incidence of canine leptospirosis in Brazil needs to be assessed Methods The same dogs in southern Brazil were sampled over two years to determine the prevalence, incidence and association of canine leptospirosis with various risk factors. Results In 2009, the prevalence was 33 (14.4%) of 228 dogs, with a predominance of serovar Canicola (33.4%). In 2010, 90 dogs were re-evaluated (the remaining dogs were lost to deaths, address changes and donations), and the prevalence was found to be 35 (38.9%) of 90, with the predominant serovar being Icterohaemorrhagiae (51.4%). Moreover, the incidence was 26 of 90 (28.9%), and the disease was statistically associated with age (2009) and street access (2010). Conclusions Our findings revealed instability in the dog population and age to be relevant risk factors for canine leptospirosis.
