ABSTRACT
ABSTRACT We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and deciduousness. The data were analyzed through a functional and taxonomic dissimilarity dendrograms, community-weighted mean trait values, parametric and nonparametric tests, and Principal Component Analysis. The largest floristic-structural similarity was observed between the lower altitude areas (700 and 900 m asl), whose Bray-Curtis distance was 0.63. The area at 700 m asl was characterized by a predominance of deciduous and semi-deciduous species, with a high number of self- and wind-dispersed species, whereas the area at 1,600 m asl exhibited a predominance of animal-dispersed and evergreen species. It was also observed that there were significant variations for leaf traits, basic wood density and maximum potential height. Over all altitudinal gradient, the ordinations indicated that there was no evidence of functional differentiation among dispersal and deciduousness groups. In conclusion, the evaluated Araucaria Forest areas presented high floristic-functional variation of the tree component along the altitudinal gradient.

Introdução e objetivos: Os objetivos deste trabalho foram avaliar o estado nutricional e de higiene oral de escolares pertencentes ao Programa AABB Comunidade e verificar a eficácia da aplicação da educação em saúde na modulação dos estados nutricional e de saúde oral. Material e métodos: Foram realizados levantamentos antropométricos e de higiene oral, além de atividades de educação nutricional e de saúde oral com 98 (Nutrição) e 55 (Odontologia) escolares de 8 a 15 anos. Resultados e conclusão: Essas atividades, bem como o reforço da alimentação por intermédio das refeições servidas na instituição, influenciaram o estado nutricional e de saúde oral dos escolares. A fase escolar é um excelente momento para a formação de hábitos alimentares saudáveis e de higiene oral que respeitem as características de cada pessoa. Os registros obtidos podem ter aplicação direta na avaliação e na reorientação do programa e também individualmente no modelo liberal das áreas profissionais envolvidas.
Introduction and objective: The aim of this study was to evaluate the nutritional and oral health status of students from the AABB Community Program and to determine the effectiveness of professional orientation on modulating nutritional and oral health conditions. Material and methods: Anthropometric and oral health surveys were used, as well as nutritional and oral health educational sessions with 98 (NutritionCourse) and 55 (Dentistry Course) students between 8 and 15 years old. Results and conclusion: These activities, as well as the nutritional reinforcement, by providing balanced meals offered by the institution, favorably influenced students´ general health condition. This educational stage seems to be an adequate moment to establish healthy nutritional and oral health habits that respect each person characteristics. These data can be applied in the evaluation and development of this particular program, just as individually in the self-employed model from these two involved professional s: Nutrition and Dentistry.
