Áreas ecologicamente estáveis como instrumento de planejamento ambiental

The population growth phenomenon, coupled with recent urbanization, is seen in all continents and generates huge pressures on the physical and biotic environment, resulting in floods in several areas, desertification in others, and also various forms of pollution that cause serious problems to human health. It is appropriate to ask, what actions can be implemented in consolidated urban areas to improve the quality of life in this environment? What growth alternatives present themselves to today's society in order to keep an acceptable level of environmental quality in urban centers? A possibility is presented herein, stemming from the application of the Biotope Area Factor (BAF; www.stadtentwicklung.berlin.de) to an area of a Brazilian municipality. Current growing waterproofing requirements fur lots of the area were assesed, comparing them with those that would be desirable by the implementation of the BAF. The associated costs of this deployment are also discussed.

Flutuação populacional de cigarrinhas-das-pastagens na Região Oeste do Paraná

The spittlebugs are considered the most important pests in tropical pastures. The damages caused by these insects decrease the production of pastures. The objective this work was to study the population dynamics of Notozulia entreriana, from June 2007 to June 2008, and the correlation with meteorological and environmental factors (rainfall, temperature, daily solar radiation and pasture height). Therefore, sampled were made in three areas of grassland in the municipality of Marechal Candido Rondon-PR. Sampling of adults and nymphs was made. Also we determined which species of spittlebugs (Hemiptera: Cercopidae) occur in the western region of Parana State. The population fluctuation of N. entreriana showed four peaks during the period of favorable development - spring / summer. The daily solar radiation had a higher correlation with the population. Rainfall, temperature and pasture height had little correlation with the population dynamics. The species that occurred with greater abundance was N. entreriana, representing 88.4% of the total insects collected in western of Parana State.

Helminth parasites of Leptodactylus podicipinus (Anura: Leptodactylidae) from south-eastern Pantanal, State of Mato Grosso do Sul, Brazil

Forty-three specimens of Leptodactylus podicipinus (Anura: Leptodactylidae) were collected in the south-eastern Pantanal, municipality of Corumba, State of Mato Grosso do Sul, Brazil in February and July 2007, and examined for endoparasites. Forty (93%) specimens were infected with at least one helminth species. The predominant parasites were nematodes (Aplectana sp., Cosmocerca podicipinus, Oswaldocruzia lopesi, Physalopteroides venancioi, Rhabdias sp.), but the trematode Catadiscus propinquus also showed high prevalence. The trematodes Infidum infidum and Travtrema stenocotyle were also found, but in only one specimen. Adult frogs showed higher parasite diversity than subadults. Leptodactylus podicipinus was preferentially infected by direct life-cycle parasites and was reported as a new host record for seven helminth species.

Caso alóctone de leishmaniose visceral canina, no município de Campo Mourão, Paraná, Brasil

This report aims to describe the first case allochthonous of visceral leishmanisasis (VL) in the municipality of Campo Mourao, Parana, Brazil, in a canine, Boxer breed, with eye and skin lesions, lymphadenomegaly and splenomegaly, attended at Veterinary Hospital at the Faculdade Integrado de Campo Mourao, after residing in the city of Campo Grande, Mato Grosso do Sul. The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.

Novos Registros sobre Meloidogyne mayaguensis no Brasil e Estudo Morfológico Comparativo com M. incognita

Almeida, E.J., P.L.M. Soares, A.R. Silva & J.M. Santos. 2008. New records on Meloidogyne mayaguensis in Brazil and comparative study with M. incognita. Meloidogyne mayaguensis is the plant-parasitic nematode responsible for a great impact on guava production in Brazil, since it has been the cause for eradication of thousand of hectares of guava plantations in the Northeastern region. In the present study, this species was detected in soybean fields of Ituverava municipality, São Paulo state, and in different vegetable crops (lettuce, cucumber, pepper and cherry tomato) in Chapada dos Guimaraes municipality, Mato Grosso state, causing root galls and other symptoms. The species was identified on the basis of the perineal pattern of females, and on the morphology and morphometry of anterior region of males. Isozyme phenotype for esterase was used for confirmation. This constitutes the first report on the occurrence of M. mayaguensis on lettuce, cucumber, pepper and cherry tomato cultures in Mato Grosso state and the first one in soybean in São Paulo state. It was found that morphological features of male anterior region and female perineal pattern are enough for the safe distinction between M. mayaguensis and M. incognita.

Flutuação populacional de Meloidogyne enterolobii em pomar de goiabeira (Psidium guajava)

The objective of this work was to study the population fluctuation of Meloidogyne enterolobii in a commercial orchard of 'Paluma' guava with five years of age, under micro sprinkler irrigation system and usual practices for this crop. In the orchard, located in the municipality of Vista Alegre do Alto (SP) Brazil and infested by M. enterolobii, five plants exhibiting nematode symptoms were selected for monthly sampling from July 2007 to June 2008. Two single samples of rhizosphere soil and guava roots were collected from each plant, with the aid of hoe to a depth of 20 cm on the projection of the trees, forming a composite sample per plant. In nematology laboratory of Faculdade de Ciencias Agrarias e Veterinarias Universidade Estadual Paulista, eggs and second stage juveniles (J2) of M. enterolobii were extracted from the samples and quantified. There was not a marked seasonal variation in the nematode population in soil or roots, possibly as a result of the guava vegetation stimulated by irrigation or the presence of invasive plants during the experimental period. However, the soil density reached a peak in January, corresponding to the month of elevated rainfall and temperatures. In roots, there were two significant peaks, in February and a major peak in August. There was a negative correlation between nematode populations in soil and roots.

Caracteristicas de padroes de drenagem de areas com entalhes erosivos no municipio de Botucatu - SP

Descriptive and quantitative characteristics of the drainage pattern of two places very susceptible to erosive process, located in the municipality of Botucatu-SP, were studied through photo-interpretative methods. The analysis and discussion of the obtained results led to the conclusion that the geologic control in the area B, masking the effect of the relief and terrain permeability, increases the drainage density, the length of channels and the angularity of the channels of 3rd and 4th order. -from English summary

Partilha de Recursos Alimentares em Peixes em um Riacho de Serra do Sudeste do Brasil

We studied the diet and food resources partitioning by fishes from the Itaúna stream, municipality of Itatinga, Southeastern Brazil. Eighteen species of fish were collected, being Microlepidogaster sp., Hypostomus sp., Astyanax sp., Phalloceros caudimaculatus and Heptapterus sp. the most frequent and abundant ones. Regarding diet, the majority of the species were observed to be insectivorous (61%), while insectivorous-herbivorous and periphyton feeders ranked 22 and 17%, respectively. The food overlap analysis revealed many cases of similarity between the diets. For most cases, however, a detailed analysis of food items and spatial distribution of the species showed differences between the couples under analysis which points toward a reduction in competition for food.

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.

Lower Permian Sphenopsids from Cerquilho, Northeastern Paraná Basin, Brazil

The Lower Permian sphenopsids Phyllotheca australis Brongniart, 1828, Stephanophyllites sanpaulensis Millan & Dolianiti, 1980a and Paracalamites australis Rigby, 1966b, from the Toca do Índio outcrop in Cerquilho Municipality (northeastern Paraná Basin, Tubarō Supergroup) are redescribed on the basis of newly collected specimens. Some aspects, such as the leafsheath opening angles of the whorls and the foliar transverse to oblique striae or wrinkles, are discussed in detail. Phyllotheca australis and Paracalamites australis are widespread in Gondwana and have no particular stratigraphic or phylogenetic value. Otherwise, the genus Stephanophyllites, although only found in the Paraná Basin and probably in Argentina (Bajo de Véliz Formation, close to the Carboniferous-Permian limit), can have a greater importance on account of some Raniganjia-like characters superimposed to a gross Phyllotheca-like morphology.

An hydrochemical answer to a legislative demand involving health risk related to water quality

Effluents and surface waters around an area involved with the inking of tissues at Itatiba municipality, São Paulo State, Brazil, were chemically analyzed with the purpose of evaluating the influence on the water quality of the chemicals released, as well to provide answers to legislative requirements related to the São Paulo State Register 997 published on 31 May 1976.

Geogenic factors affecting the selenium(IV) distribution in sediments from Madeira River Basin, Brazil

This investigation was carried out at the Madeira River basin, located in the state of Rondônia, Brazilian Amazon. Sediments from Madeira River between Teotônio and Santo Antônio waterfalls along 25 km upstream from Porto Velho, the capital of Rondônia state, and from nine lakes located around Porto Velho municipality were chemically analyzed for Se (IV) in order to evaluate the main factors affecting the Se(IV) distribution in the environment, Selenite ion was chosen to investigate the selenium behavior in the area, because acid conditions are dominant there. The importance of clays, iron oxides, organic matter and minor refractory minerals was considered in order to explain most of the obtained data.
