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

The modernization process has been introduced in the agricultural sector without any technical control. This process has provoked loss of food quality, serious damage to the worker's health and environmental degradation. The lack of technical assistance is total and farmers are not interested in the hazards involved. -after English summary

Distribution of stream macroalgae in the northwest region of Sao Paulo State, southeastern Brazil

Forty-four stream segments were sampled from May to October in 1992 and 1993 in the northwest region of São Paulo State, southeastern Brazil (19 degrees 45'-21 degrees 25'S, 49 degrees 05'-51 degrees 30'S). Thirty-six macroalgal subgeneric taxa were found and Chlorophyta was the dominant algal group (47% species), followed by Cyanophyta (33.5%), Rhodophyta (14%) and Chrysophyta (5.5%). The most widespread species were Stigeoclonium helveticum (25% sites), Batrachospermum delicatulum and Compsopogon coeruleus (20.5%). Distribution was patchy, with species number per sampling site ranging from 0 to six (3.1 +/- 1.7) and correlated positively with species abundance. Species cover ranged from 0 to 61% of the stream bottom (19.1 +/- 19.7%). Most sites (57%) were dominated by one or two macroalgae species. No significant difference was found between the frequency distribution of variables measured for streams and for total macroalgae, but the most widespread species differed for most parameters and occurred over wider ranges of environmental conditions. Mean species number and abundance were close to values found in distinct regions or biomes of North America. Higher conductance and lower oxygen values, as well as rocky substrata, generally constituted the most favourable combination of conditions for the development of macroalgae in the region. The pattern of strong dominance of few species was considered to be typical for stream macroalgal communities in general.

The use of radon (Rn-222) and volatile organic compounds in monitoring soil gas to localize NAPL contamination at a gas station in Rio Claro, Sao Paulo State, Brazil

This study focuses on the presence of radon (Rn-222) and volatile organic compounds (VOCs) in soil gases at a gas station located in the city of Rio Claro, Sao Paulo, Brazil, where a fossil fuel leak occurred. The spatial distribution results show a correlation between Rn-222 and VOCs, consistent with the fact that radon gas has a greater chemical affinity with organic phases than with water. This finding demonstrates that the presence of a residual hydrocarbon phase in an aquifer can retain radon, leading to a reduced radon content in the soil gas. The data in this study confirm the results of previous investigations, in which the method used in this study provided a preliminary fingerprint of a contaminated area. Furthermore, the data analysis time is brief, and only simple equipment is required. (C) 2014 Published by Elsevier Ltd.

Phlebotomine (Diptera: Psychodidae) survey and some considerations about epidemiological aspects of canine leishmaniasis in Rio Claro city, São Paulo, Brazil.

Between 2000 and 2004, 170 sand flies were captured in urban or peri-urban areas of the Rio Claro city, SP, Brazil. Nyssomyia neivai, the main LTA vector species in São Paulo territory, corresponded to 124 specimens (72,94%) of the total number of captured insects. Incidence of American Cutaneous (LTA) and Visceral leishmaniasis (LVA) is increasing in human and dogs in São Paulo State. Rio Claro city is located in the center-east region of the State. During 2001 and 2003, two cases of alochtonus canine LVA and an autochthonous case of canine LTA were locally diagnosed. Results indicate the risk of LVA establishment in this region. Possible role of alternative vectors in leishmaniasis transmission is discussed.

SPECIES OF COCCIDIA OCCURRING IN LAMBS IN SAO-PAULO STATE, BRAZIL

The purpose of this experiment was to characterize the species of Eimeria affecting lambs and their infection pattern. Faecal samples were collected from each animal at 14-day intervals, beginning when lambs were 2 weeks old and ending when they were 32 weeks old. The oocysts were counted and identified as E. intricata, E. parva, E. pallida, E. crandallis, E. bakuensis, E. weybridgensis, E. ahsata and E. ovinoidalis. The highest oocyst counts were observed when the lambs were 4-8 weeks old.

Hydrochemistry on a waste disposal area of sand mining activities at Analandia, Sao Paulo State, Brazil, and their implications on the mobilization of uranium

Groundwaters and surface waters from an area of treatment of sand for industrial purposes at Analandia municipality, nearly in the center of Sao Paulo State, Brazil, were chemically and isotopically analyzed with two aims: to evaluate if the anthropogenic activities that has taken place for the last 6 years is affecting the quality of the hydrological resources and to relate the hydrogeochemical behaviour of the uranium isotopes 234U and 238U with the pattern of circulation of groundwaters.

Adenocalymma ubatubensis Assis and Semir, a new species of Bignoniaceae from Ubatuba, Sao Paulo State, Brazil

Adenocalymma ubatubensis, a new species from southeastern coastal Brazil, is described and illustrated. The species is distinguished by its large pseudostipules and calyx without nectaries.

Landscape reshaping of the asylum of san francisco de paula, located in jaboticabal, Sao Paulo State, Brazil

It is a commonly known fact that there are elderly who have no family or who do not receive any kind of help from their relatives, as the family does not normally have good financial conditions to help them. These elderly live in private or public shelters and generally, they do not have enough money to cover all the necessary costs, and are forced to survive from donations. Those shelters are based, primarily, on nutrition and health. Leisure and wellbeing are usually treated with little attention, but it could be obtained in a simple and effective way: green areas, which normally exist at the site, are often misused, so they can become rest areas through simple landscape projects. It is important to mention that a garden is not just a beautiful place, but it becomes important for the daily life of older people. The objective of this work was to study the need for contemplative leisure and labor in order to improve the life quality of the elderly that live at the San Francisco de Paula Asylum, in Jaboticabal City, Sao Paulo State, Brazil. In this study, a topographic and a photographic survey was conducted and an analysis of the local ground was done. The preferences of the employees and the visitors of the building were also recorded, as well as the critical points of the area. After this primary analysis, the landscape planning was done, with the help of the AutoCAD 2004 software, prioritizing the use of plants that are not dangerous and that are easy maintained. An orchid nursery was also created in order to provide weekly workshops of orchid cultivation.

The Palm Collection of UNESP/FCAV - Jaboticabal, Sao Paulo State, Brazil

The palm collection of UNESP/FCAV, Jaboticabal, Sao Paulo State, Brazil, was created in 1966 with the aim to keep different palm species for research purposes and conservation of native species, especially those threatened. Native and exotic species comprise the collection, which is held at the institution, where several studies with different species and in different areas are undertaken. Nevertheless, palm seeds and seedlings are also distributed to other research centers. The botanical review of the collection began in 2003 and there are, currently, 143 species or hybrids, in a total of 331 specimens. Considering the most ancient species, the immediate identification of many of them was possible; however, for others, such as the Attalea, Orbignya, Syagrus and Scheelea genera, future morphological studies is required, like the karyotype one or using molecular markers. Many species have been introduced and many seeds have been currently investigated regarding their germination process for future inclusion in the collection. Some of the palms do not bloom; others, however, bloom, but do not bear fruits; and others bear fruits, but their seeds do not germinate. They are either young plants, fruits which are constantly attacked by insects, like the Syagrus species and hybrids, or dioecious plants.
