The Atlantic Forest biome, reduced to 12% of its original coverage, holds a significant portion of brazilian biodiversity, with high levels of endemism. Among the few remaining areas of the Atlantic, there is the region between the Complex of Cantareira and the municipality of Nazaré Paulista, which will be the object of study of this work. Using the concepts of Landscape Ecology, and analysis of thematic maps, this study aims to characterize the region in a ecologically scaled perspective, identifying two types of hotspots: i) for conservation and ii) for maintain habitat connectivity. Concepts of Landscape Ecology as landscape structure, patches, matrix, corridors (structural and functional) and connectivity, as well as their effects on local biodiversity was adopted and applied in the study region. We also analyzed the effects of roads, hydrographic system, Permanent Protection Areas (PPAs), and Conservation Units for flora and fauna maintenance at regional scale. This allowed us to define strategies and priority areas for the conservation and restoration of forest fragments of Atlantic Forest remnants within the study region. This study generated relevant knowledge for a better planning the region in order to create best conditions for the maintenance of regional biodiversity, and consequently, allowing to improve the quality of life for local population

O trabalho apresentado é constituído de dois capítulos distintos, ambos com preocupação recorrente de realizar uma ciência que tenha interface com a realidade, uma Ecologia aplicável às questões e demandas da sociedade contemporânea como ferramenta para compreender a realidade, mediar conflitos. No capítulo I - Integrando o meio físico, biológico e sócioeconômico na proposição de novos Índices de Sensibilidade Ambiental (ISA) propomos o desenvolvimento de índices que combinem aspectos bióticos, socioeconômicos e ecológicos como: a) Índice de Sensibilidade Ambiental Biológico (ISAB), pautado na comunidade de mamíferos de médio e grande porte; b) Índice de Sensibilidade Ambiental Socioeconômico (ISASE), composto pelo tipo de atividade econômica e pelas características da comunidade do entorno e c) Índice de Sensibilidade Ambiental Ecológico (ISAEc). No capítulo II - Contribuição da área do fragmento e dos corredores ecológicos para a comunidade de mamíferos de médio e grande porte das matas ciliares, ressaltamos a importância da Ecologia da Paisagem para a presença/ausência de espécies de mamíferos de médio e grande porte. Quais correlações são relevantes e como as métricas da paisagem têm influência sobre a comunidade da mastofauna. Há a clara intenção de compreender a realidade e propor soluções para as problemáticas modernas visando o bem estar da sociedade e a conservação e preservação da biota

A vegetação ribeirinha é conhecida como o conjunto de formações que se encontram associadas aos corpos d’água, ocorrendo ao longo dos cursos d’água e no entorno de nascentes, formando um mosaico vegetacional. É de vital importância na proteção de mananciais, controlando a chegada de nutrientes, sedimentos e a erosão de ribanceiras, atua na estabilidade térmica e abastece o lençol freático a partir da contenção de águas pluviais, além de exercer um papel fundamental como corredores ecológicos de fluxo gênico animal e vegetal. No Brasil, há legislação que protege tais áreas, entretanto, estas vem sofrendo sistemática degradação por desmatamento, despejo de esgotos domésticos e industriais, canalização e desvio de cursos d’água. O estudo presente teve como objetivo caracterizar a florística e a estrutura fitossociológica de três fragmentos do ambiente ribeirinho localizados na Fazenda Água Branca, em Ajapi, Rio Claro - SP. Através de parcelas de 10x10m, foram amostrados todos os indivíduos com PAP ≥ 10cm. Foram estabelecidas 16 parcelas na vegetação ribeirinha com influência fluvial sazonal ao longo do Ribeirão Claro, tratadas no trabalho como floresta ciliar. Foram estabelecidas 14 parcelas distribuídas em dois fragmentos de vegetação ribeirinha com influência fluvial permanente, tratadas ao longo do trabalho como floresta paludosa. Na mata ciliar, foram amostrados 316 indivíduos, pertencentes a 32 famílias, distribuídos em 74 espécies. As espécies mais importantes foram: Syzygium cuminii, Esenbeckia febrifuga e Croton urucurana. As famílias com maior riqueza foram: Myrtaceae, Fabaceae, Euphorbiaceae e Meliaceae. O índice de diversidade (H’) encontrado foi 3,62; valor esperado para Florestas Estacionais Semideciduais. Na mata paludosa, foram amostrados 469 indivíduos, pertencentes a 34 famílias, distribuídos em 60 espécies... (Resumo completo, clicar acesso eletrônico abaixo)

Habitat loss and fragmentation of landscapes endanger the planet’s biodiversity. Strategies for identify priority areas for conservation and restoration of biodiversity rich areas becomes essential for the planning of the management of these landscape become successful. This study aims to propose a novel, transparent and replicable method for choosing priority areas for restoration, and includes the following steps: (a) identification of regional biodiversity hotspots for conservation; (b) identification of priority areas for restoration with the greatest potential to increase the connectivity of the fragments already existing; (c) estimate the potential richness of understory birds before and after restoration, analyzing the gain of species for the future scenario. In order to identify the corridors to be restored in a future scenario we considered the approach of multiple corridors, which aimed to connect the main fragments within the region through analysis of multi-paths. Already existing regression models were applied to estimate the richness of the landscape considering three models: a) species richness as a function of patch area of the fragment selected as hotspots; b) richness as a function of areas connected by structural corridors and c) connected area for species which are able to access nearby fragments within 20m. The gain of species for future scenario which consider the potential restoration of selected areas was estimated. Based on our results we observed that species that use corridors showed the highest increment of species richness of understory birds. As a result it had to restore corridors to model species with the ability to use forest corridors was the highest gain potential species richness of understory birds. The methods proposed method in this study appears provide new ways to ensures a better cost / benefit relationship for restoration projects by increasing the chances of better reach high levels of...

The present article starts from the initial consideration that, in the perspective of the investigations of the Brazil/Germany literary relations, not always the study of the presence of Brazilian literary works in Germany has been receiving sufficient attention in Brazil. Initially, the natural existence of mental paths is signalized. This fact, in a way, guides the general lines of the critical Brazilian thought in the consideration of aspects of the cultural and literary dialog here in question. This consideration favors the movement that goes from Germany to Brazil, which doesn’t give enough space for the study of the opposite movement. Finally, some historical literary elements are presented, which can base deeper studies of the literary relations Brazil/Germany in the sense that here is intended to be rescued, i.e., the one that goes from South America to Europe.

In order to reduce the sedentarism and to improve population's health condition, many physical activity incentive programs have been stimulated. As a result, many people have adhered to street racing, but their health condition is almost always ignored. The aim of this study was to evaluate street racers' health condition, identifying the presence of cardiovascular risk factors as well as problems associated to street racing. The study case was composed by 111 racers from the town of Bauru (94 men and 17 women) aged in average 39±13 years old, who were evaluated in 4 street race competitions. The subjects answered to an anamnesis with questions about their socioeconomic status, medicine use, cardiovascular risk, physical exercise practices, and issues related to racing and injury. Weight (kg) and height (m) were measured to calculate the body mass index (BMI, kg/m²) as well as systolic and diastolic blood pressure (BP), heart rate (HR), abdominal circumference (AC), and flexibility. It could be observed that the majority of racers were Caucasian, married and belonged to social classes over C. The prevalent age was between 18 and 35 years old (42%). Among the participants, 38.7% have already undergone some kind of surgery and 13% declared having some health problem. The questionnaire pointed out that 36% had low and moderate cardiovascular risk. It could be noticed from the AC that 10% of men and 18% of women had high cardiac risk. Among the tested, 43.2% (24.3% altered and 18.9% borderline) showed high BP on the day of the test, but only 2.7% had self-declared hypertensive. In relation to injury, 36% had already had lesions of some kind, 27.5% of which had occurred in the last 8 months. 66.6% had derived from training or racing competitions and the knee was the mostly affected body part. Only 43% had professional orientation by a physical education teacher during their training and the main reasons for them to begin racing practice were...

Braking visual control was studied in recreational cyclists through the manipulation of bicycle’s velocity at braking initiation (low, medium, and high) and approaching trajectory (straight and curved) with respect to a stationary obstacle. The hypothesis was that the type of trajectory, exclusively or interacting with initial velocity, would affect time to collision visual information (tau margin) and its fi rst derivative in time (tau-dot), respectively, in the onset and during braking. The results revealed that velocity affected signifi cantly tau margin while tau-dot remained unaltered independently of condition. The type of trajectory clearly did not affect the visual control of braking in cyclists.

Objective: To determine the prevalence of exercise-induced bronchoconstriction among elite long-distance runners in Brazil and whether there is a difference in the training loads among athletes with and without exercise-induced bronchoconstriction. Methods: This was a cross-sectional study involving elite long-distance runners with neither current asthma symptoms nor a diagnosis of exercise-induced bronchoconstriction. All of the participants underwent eucapnic voluntary hyperpnea challenge and maximal cardiopulmonary exercise tests, as well as completing questionnaires regarding asthma symptoms and physical activity, in order to monitor their weekly training load. Results: Among the 86 male athletes recruited, participation in the study was agreed to by 20, of whom 5 (25%) were subsequently diagnosed with exercise-induced bronchoconstriction. There were no differences between the athletes with and without exercise-induced bronchoconstriction regarding anthropometric characteristics, peak oxygen consumption, baseline pulmonary function values, or reported asthma symptoms. The weekly training load was significantly lower among those with exercise-induced bronchoconstriction than among those without. Conclusions: In this sample of long-distance runners in Brazil, the prevalence of exercise-induced bronchoconstriction was high.

O objetivo do presente estudo foi comparar o sinal eletromiográfi co, a frequência e a amplitude de passada entre diferentes intensidades de corrida: 60%, 80% e 100% da velocidade máxima em dois protocolos incrementais. Participaram deste estudo 11 corredores do sexo masculino. Os protocolos de corrida foram realizados com velocidades iniciais de 10 km.hr-1, com incrementos de 1 km.hr-1 a cada três minutos até a exaustão, que diferiram em relação ao intervalo entre cada estágio incremental: 30 e 120 segundos. Foram analisados valores RMS dos músculos iliocostal lombar, reto femoral, vasto lateral, vasto medial, bíceps femoral, tibial anterior, e gastrocnêmio, e a amplitude e frequência de passada. Os valores RMS mostraram aumento entre as intensidades para quase todos os músculos, e não foram influenciados pelo tipo de protocolo utilizado para maioria dos músculos. A frequência e amplitude de passada apresentaram contribuições percentuais diferenciadas para o aumento da velocidade de corrida.
