Biologia populacional de Cyphocarax modestus no córrego Ribeirão Claro, município de Rio Claro (SP)

This work aimed a better understanding of the annual cycle of Cyphocarax modestus in the reservoir of water captation of Ribeirao Claro stream. The growth parameters were estimated through the analysis of length distribution and the relationships among time of smaller growth, alimentary activity, fat accumulation and reproductive period were considered. Besides, the instantaneous rate of natural mortality was calculated. Monthly samplings were accomplished in the Ribeirao Claro stream, in the reservoir of water captation of Rio Claro city. For that, 50 m of wait net was used, with meshes of 1.5, 2.0, 2.5, 3.0 and 3.5 cm measured between adjacent knots. The ELEFAN I program was used to estimate the growth parameters, and its application was done using the FISAT program. It was also used the seasonal version of von Bertalanffy's growth curve. It was considered that the reproduction of C. modestus is annual and concentrated from December to February, allowing the identification of different modas in the distributions, an essential condition for the conduction of that analysis type. The estimated parameters were: K = 0.34/year, L [infinity] = 15.40 cm, C = 0.2, Wp = 0.6 and M = 0.949/year, with the identification of four cohorts. The physiologic sequence in the annual cycle of the specie could be noted when data of accumulated fat in the visceral cavity, alimentary activity, reproduction time and time of smaller growth were analyzed together. It was noted that with the beginning of the maturation of gonads, the energy resources stopped being invested in the growth and passed to be used for reproduction.

Caracterização dos elementos físicos da bacia do córrego Santo Antônio (Rio Claro/SP)

O objetivo desta pesquisa foi caracterizar os elementos físicos da bacia do córrego Santo Antônio, buscando compreender a influência que a área de entorno dessa bacia exerce sobre a Floresta Estadual Edmundo Navarro de Andrade (FEENA). Para isto, foram elaboradas as cartas geomorfológica e de uso do solo, além da compilação de dados geológicos, pedológicos e climáticos. Essa influência foi avaliada em termos da dinâmica de remobilização de materiais provenientes das nascentes, que não pertencem a FEENA, e que se constituem, portanto, em área de uso agrícola. A análise das características físicas indicou que essa área é susceptível a ação dos processos morfogenéticos e que estes foram intensificados e acelerados pelo uso do solo ao redor das nascentes. Verifica-se, assim, a necessidade de se reavaliar esse uso e de se fiscalizar o cumprimento da própria legislação ambiental, no que se refere ao uso e ocupação do território, em fundos de vale.

Propriedades reológicas de matérias-primas do Pólo Cerâmico de Santa Gertrudes provenientes da Formação Corumbataí (região de Rio Claro, SP)

Programa de apoio à legalização mineral de olarias da região de Rio Claro (SP)

Esse artigo apresenta os resultados de um projeto denominado de Projeto Parceria, desenvolvido no período de 2007 a 2010, com objetivo de orientar, tecnicamente, os oleiros associados da ASCER, para a correta condução das atividades de extração de matéria-prima das jazidas utilizadas pela indústria oleira. As atividades desenvolvidas, nesse projeto, contemplam a legalização da situação minerária das atuais áreas de extração, orientação em relação à recuperação das áreas degradadas pela mineração e caracterização cerâmica dos materiais argilosos utilizados na produção de tijolos. Fizeram parte desse estudo quatorze Olarias situadas na região de Rio Claro (SP). A legalização das atividades de extração mineral, na área da jazida de cada olaria, conduziu, automaticamente, à legalização ambiental, que está sendo atualmente executada. Duas olarias não puderam regularizar as suas extrações, pois as áreas de suas propriedades estavam oneradas no DNPM. Outras duas olarias não possuíam documentações referentes à parte jurídica das empresas, necessárias para legalização de suas áreas. Os materiais argilosos utilizados pelos oleiros foram caracterizados quanto às suas aplicações cerâmicas como material nobre para a fabricação de telhas e tijolos, gerando produtos de alta qualidade.

Probabilidade de ocorrencia de periodos secos e chuvosos em Rio Claro - SP.

Using the daily rainfall data from 1961 through 1980 the frequency of dry and wet periods was determined. The results of the frequency distribution of dry and wet periods indicated that observed data fit very closely an equation of the type Y = aebn. -after English summary

Consequencias da modernizacao da agricultura: o uso indiscriminado de praguicidas no municipio de Rio Claro (SP)

Gênese e Classificação da Coquina de Camaquã, Formação Corumbataí (Neopermiano), na Região de Rio Claro, SP

Analysis of the taphonomic signatures of a well preserved, silicifled coquina (Pinzonella neotropica assemblage) from the Camaquã outcrop, upper part of the Corumbataí Formation (Late Permian), in the Rio Claro region, state of Sáo Paulo, allowed interpretation of processes involved in its origin as related to high energy events (storms). The coquina occurs as a lenticular body, 2-11 cm thick and extending laterally for about 120 m. Basal contact of the coquina is sharp and erosive. Its upper contact is sharp. The concentration is dominated by pelecypods including the shallow burrowers (Pinzonella neotropica, Jacquesia brasiliensis), intermediate burrower (Pyramus anceps) and semi-infaunal forms (Naiadopsis lamellosus). All these species are suspension feeders. Besides sand-sized or even smaller shell fragments, there occur disarticulated, complete shells which are commonly abraded but do not show any signs of bioerosion or incrustation. In vertical side view, the shells are mainly convex-up, nested or stacked, while in plan-view they show random orientation. Multiple discontinuous grading is visible. These taphonomic signatures suggest that the origin of the skeletal accumulation is related to high energy events (possibly storm flows) in a proximal environment. The amalgamated nature of the Camaquã coquina records several episodes of erosion and deposition.

Nova contribuiçao ao conhecimento da formação Rio Claro (T) na Folha Rio Claro (SP)

The Rio Claro Formation mainly occurs in the county of Rio Claro (SP) lying unconformably on Paleozoic and Mesozoic rocks. Its thickness is 30-40 m. It shows fine to coarse, regular to poor sorted, Triable sandstones and conglomerates with quartzite and quartz clasts in the base. Thin layers of mudstone occur interbeded. Stratigraphic maps had been elaborated in recent analyses allowing to improve the knowledge about the formation. The biggest thicknesses occur on the east part of the studied area. The coarse/fine clastic ratio map demonstrates that fine sediments are concentrated in the east side, and suggests the existence of barriers which conditioned perennial water body (or bodies) where decantation took place (east, south and southeast sides). The structural contour map of the Rio Claro Formation base indicates a NW/SE trough which was the main depositional axis. The integrated analysis demonstrates that the formation is formed by lacustrine, fluvial and debris flows deposits whose source area was located on NW side, with coalescent alluvial fans from where braided to psamitic meandering fluvial channels came. The location of the source area suggests no link with the Corumbataf River paleo-terraces.

Diagnóstico ambiental do rio corumbataí em trecho urbano do município de rio claro, SP

The environmental analysis is an important tool used in forecasting and mitigation of environmental problems. Focusing on the occupation of marginal areas of the Corumbataí River in an urban stretch in the city of Rio Claro (SP), this study aimed to gather information on situations of risk, both to the environment and the population, verified in that area. Through field observation and in specific studies, the geological and geotechnical aspects, the characteristics of surface waters and aspects of urbanization were analyzed. The results show that the environmental problems diagnosed are related to lack of planning in the occupation of the area. Moreover, the natural characteristics of the physical environment expose people to risks such as floods and soil slides.
