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.

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.

This paper presents the partial results of an investigation about school libraries in countryside schools of the public educational system in the state of Parana. The work is based on reflections about the literature related to the theme and the analysis of this reality. It aims at characterizing the subjects of the countryside school, the physical space, materials and common practices at the school libraries. The work describes the influence of the aspects aforementioned on the existence, planning and development of activities, also describing their contribution to the formation process of school subjects. The investigation also performs a descriptive field research, employing direct observation and the application of a survey in 425 countryside schools, considering a total number of 2120 schools in the Parana school system. The survey obtained a return rate of 83% from representatives of public countryside schools in Parana. The results indicated that the schools need a project for reading and writing, in which the library would be engaged. The paper argues that state and the university should contribute to the formation of the professionals of the institution and that the school library should be open to the community, acting both as a service provider and a stimulator of writing and reading practices. The investigation concludes that it is necessary to 'occupy the libraries of the countryside schools', understanding them not only as a communication spot, but also as a place for knowledge production. Furthermore, the authors suggest the library materials should be produced locally and that the state should turn this practice into a public policy.

The present study had as the main purpose to verify the teacher’s formation who update in the child education institutions of the Irati city (Parana State – Brazil), throughout the years of 2005, 2006 and 2007, and their implications for the pedagogical actions. Seven institutions they had participated of the study. The data collection was made by means of documents of the institutions. A predominance of secondary school in the formation of the teachers was verified, even so had still one high index of professionals with formation level below of this requirement to the legislation. We conclude that it has urgency to the implementation of public politics directed toward the child education, with focus for the formation’s teachers.

This article is the result of one ampler researching project that discusses about the limits and possibilities of the democratic management at Federal Technological University of Paraná (UTFPR). The main purpose of this text is to demonstrate that the elections to the choosing of directors of campus, recently presented, and the structuring and functioning of the collegiate counsels with deliberative forces of this institution, are elements that contribute to a relative democratization in the form of management of UTFPR.

The social attitudes of teachers are considered highly relevant variables in the process of construction of school inclusion. The aim of the study was to describe the elementary school teachers’ social attitudes towards the inclusion and to identify the variables related to them. The sample consisted of 172 female teachers with ages ranging from 18 to 57, mean age of 37 and standard deviation of 7,9 years of age. A questionnaire was used to describe the participants. A Likert Scale of social attitudes towards inclusion was used. The results show that the chronological age, the level of basic training, the area of specialization, and the time of teaching experience have no significant effect on the social attitudes. The teachers with experience in teaching disabled students were more favorable towards the inclusion than those without such experience. It was concluded that the social attitudes towards inclusion may be complexly determined by different variables, demanding further studies for its enlightenment.
