Detecção de Xanthomonas axonopodis pv. phaseoli em sementes de feijoeiro provenientes do estado do Paraná, Brasil

O crestamento bacteriano comum do feijoeiro causado por sobrevivência e disseminação da Xap, a semente representa o mais Xanthomonas axonopodis pv. phaseoli (Xap) é a principal doença eficiente. A qualidade sanitária de 34 amostras de sementes de feijoeiro do feijoeiro comum no Brasil. O patógeno encontra-se disseminado produzidas no estado do Paraná, nas safras 1998/99 e 1999, foram em todas as regiões produtoras do país, porém com maior importância avaliadas quanto à presença de Xap em macerados de sementes nos estados do Paraná, Rio de Janeiro, São Paulo e na região do Brasil plaqueados em meio semi-seletivo. Cinqüenta por cento dos lotes de Central, sobretudo na safra das águas. Dentre os vários meios de sementes foram portadores de Xap com incidência de 0,1% a 1,7%.

A saúde bucal em pauta: análise de registros dos Conselhos Municipais de Saúde de municípios pertencentes à 17ª Regional de Saúde do Estado do Paraná, Brasil

O presente estudo teve como objetivo a análise das intervenções em saúde bucal, registradas em atas de reuniões, de 15 Conselhos Municipais de Saúde, próprios de municípios pertencentes à 17ª Regional de Saúde do Estado do Paraná. A análise documental deu-se a partir da identificação das temáticas em saúde, com ênfase na categorização por assunto das intervenções em saúde bucal. Os resultados evidenciaram os registros relativos à programação e organização da prestação de serviços, seguida pelo orçamento em saúde, como sendo os mais freqüentes do conjunto de temáticas analisadas. Pôde-se identificar, em 90 atas das 591 estudadas, o total de 134 registros de intervenções em saúde bucal. Por meio da análise desses últimos, percebeu-se que as intervenções em saúde bucal eram relatos de ações já concretizadas, desprovidas de características propositivas quando analisadas sob a dimensão do planejamento em saúde. Sinaliza-se para a necessidade da categoria odontológica de adquirir um maior padrão de representatividade nesses espaços, de forma a possibilitar vínculos importantes no processo de planejamento e de fortalecimento da saúde bucal enquanto direito de cidadania.

Persistência de mamíferos de médio e grande porte em fragmentos de floresta ombrófila mista no estado do Paraná, Brasil

The Araucaria Forest is now represented by remnants of what was a continuous area of about 200,000 km(2). Medium and large mammals inhabiting this forest have suffered the impacts from the disturbance process and environmental degradation. Thus, this study determined which medium and large mammal species still inhabit the remnants of this vegetation type in Western Parana State. Three study areas, with 520, 405 and 135 hectares, consisting of stretches of primary forest mixed with secondary forest, were considered for mammal inventory. The evidence of mammals was verified directly (views) and indirectly (traces, trichology and interviews with local dwellers). It was recorded 32 species (including one exotic and two small ones), belonging to eight orders and 18 families. Nine animals of these species are at risk of extinction in the Parana State and five configure with insufficient data in the List of Endangered Species of the state. The results of this study indicate the great importance of these forest fragments in the conservation of several medium and large mammals in the Araucaria Forest of Parana State. Nevertheless, due to the negative pressures that these areas have been suffering, immediate and concrete public actions are required to ensure the maintenance of these mammal populations.

Sinalização visual e biologia reprodutiva de Dendropsophus werneri (Anura: Hylidae) em área de Mata Atlântica no estado do Paraná, Brasil

We studied the reproductive biology and visual signaling of Dendropsophus werneri, whose distribution is limited to the Atlantic Rain Forest. The fieldwork was carried out in the Estação 2 do IAPAR, municipality of Morretes, state of Paraná, Brazil, from August 2006 to March 2007. Additional information on reproduction was gathered in the Reserva Natural Salto Morato, municipality of Guaraqueçaba, state of Paraná, Brazil, from September 2006 to March 2007. Males were smaller than females. Males called throughout all the study period in Morretes, but were active only during three months in Guaraqueçaba; males called from low vegetation along the edge of temporary ponds in open areas. The visual signaling was observed in two contexts: (1) aggressive behaviors between two males and (2) during the reproduction, by amplectant males. In the territorial behavior, males exhibited both aggressive and mixed calls, visual signaling as well as physical combats. We also recorded satellite behavior in four males. The mean egg number per clutch was 244 ± 32 eggs, varying between 188 and 310 eggs. We observed two reproductive modes: Mode 1 and Mode 24. In the present study, Dendropsophus werneri showed elaborated social interactions involving visual signaling, territorial behavior, mating bahavior with tactile stimuli, and two different reproductive modes, demonstrating its complex reproductive biology.

Avaliação microbiológica e físico-química de leites uht produzidos no Estado do Paraná - Brasil

The present work analyzed 150 UHT whole milk samples from three different brands, commercialized in city of Palotina (Paraná, Brazil), between October of 2004 and February of 2005. Mesophilic aerobic bacteria counting results were compared to the Agriculture Ministry of Brazil official standards (RTIQ) for UHT milk. 36 (24%) of the sample presented higher mesophilic bacteria counting according to the standards. Also, were proceeded physic-chemical analyses of those samples. 7.3% of the acidity results, 29% of crude fat and 50.7% of dry matter without fat were disagreeing to RTIQ. All samples accorded to the standards for cryoscopy and alcohol stability tests.

Microhabitat de Tolypothrix distorta Kütz. ex Bornet & Flahault (Microchaetaceae, Cyanophyta) em dois riachos da região Centro-Sul do Estado do Paraná, Brasil

This study aimed to evaluate some microhabitat characteristics of two populations of Tolypothrix distorta in streams from midsouthern region of Paraná State on a seasonal period. Each population was monthly investigated for the abundance of T. distorta and environmental variables such as depth, current velocity, irradiance, richness, and substrate diversity (H') using the quadrat technique for each sample unit (n = 7-10). For each segment the following physical and chemical water variables were also measured: temperature, oxygen saturation, specific conductance, pH, and turbidity. The seasonal period of higher abundance (percent cover) occurred during the months corresponding to summer/fall for both populations. The analyses also showed that populations had lower niche width and wide variation under the environmental conditions, characterizing the species as a generalist in the use of resources. Faster water flow and larger substrates favored the development of T. distorta, which may be related to the species morphological characteristics, thallus type that consists of tangled filaments formed by tuft and covered with thick gelatinous coats.

Estrutura das comunidades de macroalgas da bacia de drenagem do rio Cascavel, Estado do Paraná, Brasil

The drainage basin of Cascavel River is almost entirely within the urban perimeter of Guarapuava, Paraná State, Brazil. Seven stream segments were sampled in two seasons (summer and winter). We found 12 taxa of macroalgae with a dominance of Chlorophyta (seven taxa) followed by Cyanophyta (three taxa), Heterokontophyta and Rhodophyta (one taxon each). Richness, diversity, and evenness were higher during the winter while the abundance and dominance were higher in the summer. Among the microenvironmental characteristics, the current velocity was the only one that differed significantly between the periods. The regression analysis revealed that the richness of the substrate was responsible for the variation in richness, diversity, evenness, and dominance during the summer period. During the winter the current velocity was responsible for the variation of species diversity. A cluster analysis of macroalgal communities did not group points in the same temporal period. The Canonical Correspondence Analysis (CCA) showed that the segments were close to each other because of the occurrence of one or a few species in common. The patterns of spatial and temporal distribution of stream macroalgae seem to be strongly influenced by microhabitat characteristics at different scales.However, they aresupported by regional variables.

Análise estrutural em relictos de cerrado no parque estadual do Guartelá, município de Tibagi, estado do Paraná, Brasil

This study was accomplished in existing Cerrado's relicts at State Park Guartelá, Tibagi, PR (24°39'10S and 50°15'25W), which represent one of the last extreme-meridional remanescents of this type of formation. Fifty plots with dimensions of 5x5m were allocated for phyto-sociological analysis, including in the sample individuals with height ≥ 1 m, divided into two samples to evaluate the following strata: a) upper-plants with DAS ≥ 3 cm, and b) intermediate - plants with DAS <3cm. Moreover, in each plot, there were established sub-plots with dimensions of 1x1m for sampling the lower stratum, comprised by individuals with height <1m and >10cm. The complete survey found 1340 individuals distributed in 28 families, 66 genera and 115 species. The diversity index was higher for the mean component (H'=3.30), followed by the superior component (H'=3.09) and the inferior (H'=2.91). The frequent occurrence of bushes is a remarkable characteristic of the physiognomy of the areas inside the park and 82 % of the populations studied are distributed in aggregated standard. Because it is a marginal region of occurrence of cerrado vegetation, now under the influence of a subtropical climate, more humid and cold, compared to the core area of this biome, it is noted that these areas are characterized by a decrease in stature, richness and diversity of its flora. Nevertheless, they preserve typical species of the Brazilian Savannah; but, due to their distribution in relicts and been, in part, devastated, some are included in the red list of endangered plants in Parana state, which evidences the importance of conservation and management of these areas.
