The occurrence of proteocephalid cestodes in tucunaré Cichla sp., captured monthly, between August 2000 and August 2001, in Paraná River, Presidente Epitácio, SP, was evaluated. From 128 specimens, 71 (55.6%) were parasitized by Proteocephalus macrophallus (Diesing, 1850) and/or P. microscopicus (Woodland, 1935). Total mean abundance and intensity were 157.08 and 223.41, respectively. The highest prevalence (90%) mean abundance (1,122.4) and intensity indexes (1,247.11) occurred in February 2001, while in September 2000 there were no observed animals infected by cestodes. No relationship between the sex of the host and parasitological indexes was found.

The closure of two phases of the dam at the Porto Primavera Hydroelectric Plant on the Paraná River flooded a flawed system located in the Municipality of Presidente Epitácio, São Paulo state, favoring the proliferation of aquatic weeds. This study aimed to observe the population ofMansonia humeralisin the area, monitoring the richness, diversity, and dominance of this species both before and during different phases of reservoir flooding as well as evaluate its possible consequences concerning human and animal contact. Adult mosquitoes were collected monthly in the following periods: at the original level, after the first flood, and after the maximum level had been reached between 1997 and 2002. Collection methods used were an aspirator, a Shannon trap, and the Human Attractive Technique. A total of 30,723 mosquitoes were collected,Ma. humeralisaccounting for 3.1% in the preflood phase, 59.6% in the intermediate, and 53.8% at maximum level. This species is relevant to public health, since the prospect of continued contact betweenMa. humeralisand the human population enhances the dam’s importance in the production of nuisance mosquitoes, possibly facilitating the transmission of arboviruses. Local authorities should continue to monitor culicid activity through sustainable entomological surveillance.

This study is part of the limnological monitoring undertaken by the Energy Company of the State of São Paulo (CESP) during the filling up process of the Porto Primavera Reservoir (Hydroelectric Power Plant Engenheiro Sérgio Motta). This reservoir, located in the high Paraná River between the States of São Paulo and Mato Grosso do Sul, is the fourth largest in the country. The first filling up phase started in December 1998 and the second phase in March 2001. Samples for benthic community and sediment characteristics analysis were quarterly collected between August of 1999 and November 2001 and also in August of 2002 (11 sampling campaigns). Samplings were carried out at 13 stations distributed in the reservoir, and at one point located downstream of the dam. 128 invertebrate taxa were identified, being Mollusca, Annelida, Insecta and Nematoda the dominant groups during almost the whole study period. Insecta was the best represented class (9 different orders), and Diptera contributed with higher number of taxa, 63. The exotic species of bivalve Corbicula fluminea was recorded in all sampling stations showing its great capacity to colonize new habitats in the neotropical region. Noticeable variations in the fauna density were observed, considering both different periods and locations. The maximum density of organisms (mean value of 7812 ind.m-2) was recorded in the center of the reservoir, and the minimum (mean value 9 ind.m-2) in the more lacustrine area near the dam. The greatest species richness per sample (24 taxa) was observed in the reservoir upstream (fluvial zone). The maximum diversity (Shannon-Wiener Index) per station/period, 3.82 and 3.86 bits.ind-1, were calculated in the transitional river/reservoir zone during the beginning (August 1999) and in the reservoir central zones in the end (August 2002) of the filling up period, respectively. There was no clear relation between the distribution of the different faunistic groups and the sediment granulometric characteristics. However, the decrease or even total absence of organisms was observed at stations with high organic matter concentration (>40%) in a low degradation state (coarse detritus). This fact may be related to the lack of sediment deposits, which would cause difficulties to the fixation of the benthic fauna. Additionally, in those conditions more reduced chemical conditions are expected in function of the intense decomposition process of the flooded vegetation.

O objetivo deste trabalho é inventariar as espécies de serpentes encontradas na divisa entre os estados de São Paulo e Mato Grosso do Sul, nas proximidades do Rio Paraná, tendo como referência os municípios de Santa Fé do Sul (SP) e Aparecida do Taboado (MS) e incluindo os municípios adjacentes. Com o auxílio da comunidade, corpo de bombeiros e secretaria de saúde, foram coletados dados acerca da ocorrência de serpentes na região. Foram registrados, preliminarmente, um total de 11 gêneros, 12 espécies e 34 espécimes de serpentes distribuídas em quatro famílias (Boidae, Elapidae, Viperidae e Dipsadidae). No Noroeste de São Paulo, foram encontradas 10 espécies, 3 delas apenas encontradas no estado de São Paulo, enquanto que no Mato Grosso do Sul, 9 espécies, 2 delas apenas encontradas no estado de Mato Grosso do Sul. As demais espécies foram encontradas em ambos os estados. Foi registrado que a ocorrência de Boa constrictor é notoriamente maior que a de outras espécies, sendo 60% mais alta que a segunda maior ocorrência a de Erytrolamprus Poecilogyrus. Sendo uma análise comparativa, não há uma grande diferença, do número total de espécies em ambos os estados de um estado para o outro. Em relação à área da saúde, os dados revelam que há maior quantidade de acidentes ofídicos na cidade de Paranaíba no estado de Mato Grosso do Sul.   INVENTORY OF SNAKES: COMPARATIVE ANALYSIS AROUND PARANÁ RIVER BETWEEN THE NORTHWEST OF THE STATE OF SÃO PAULO AND EAST OF THE STATE OF MATO GROSSO DO SUL   ABSTRACT This paper aims to inventory snakes species found in the border of both São Paulo and Mato Grosso do Sul States, around Paraná River, having as reference the municipalities of Santa Fé do Sul (SP) and Aparecida do Taboado (MS), including bordering municipalities. Data about snake’s incidence in that region was collected with the help of the community, Fire Brigade and Health Secretary. At first, it was reported, a total of 11 genres, 12 species, and 34 specimens of snakes distributed in four families (Boidae, Elapidae, Viperidae and Dipsadidae). In São Paulo northeast 10 species were found, 3 of them were only found in São Paulo, whereas in Mato Grosso do Sul, 19 species, 2 of them were found in Mato Grosso do Sul. All the other species were found in both States. It was recorded that the incidence of Boa constrictor is notoriously higher than the incidence of other species, being 60% higher than the second one for Erytrolamprus Poecilogyrus. It is a comparative analysis, thus there is not a big difference in the total number of species for both States. Regarding health issues, the data presented a higher quantity of ophidian accidents in the city of Paranaíba in the State of Mato Grosso do Sul.   Keywords: Inventory of Snakes. São Paulo-SP. Mato Grosso do Sul-MS.

AbstractThis study aimed to evaluate the helminth parasites ofGeophagus proximusfrom the São José dos Dourados River, a tributary of Paraná River, Ilha Solteira Reservoir, São Paulo State, Brazil. From May 2006 to May 2007, 116G. proximusspecimens were examined and seven different taxa of helminth were collected and identified: proteocephalidean plerocercoids (Cestoda); metacercariae ofAustrodiplostomumcompactum, Clinostomum heluansandClinostomumsp. (Trematoda); andRaphidascaris(Sprentascaris)hypostomi, and larvae ofRaphidascarissp. andContracaecumsp. (Nematoda). All parasites presented the typical aggregated pattern of distribution, as well as the presence of a high number of larval stages, an absence of influence of the host sex and seasonality upon community parameters, as well as a correlation between species richness and host body weight. Moreover, with the exception ofA. compactummetacercariae, all helminths found in this study are reported for the first time inG. proximus.

This paper studies the cartographic products associated with the Tiete River Exploration Report, (1905) published by the Geographical and Geological Committee of the São Paulo Province. The expedition, from the Bar of the Jacaré-Guassú River to the Paraná River, led to the mapping of the Tietê River, which, along with others, is part of the efforts made by this state agency so that there was no longer a great region called "Unknown hinterland inhabited by Indians" in the official map of the Province of Sao Paulo. The purpose was not only to map, but also to raise the mineral resources, the geology, focused on the types of soil and its agricultural potential, and the navigability of rivers for transporting people and goods. The data obtained are studied (altitudes, longitudes, magnetic declination), surveys paths, equipment used, work methodology and the Cartography produced: General Map, Partial Maps, Profile, Cross Sections and others.
