The Brazilian campos rupestres (high-altitude grasslands) are very important on the world conservation scenario because of high species richness and endemism. These grasslands are regarded as threatened ecosystems due to intense, on-going disruption by man's activities. The aim of this study was to describe the reproductive and vegetative phenological patterns of six shrub species endemic to these grasslands in the Espinhaço Range, sympatric in Serra do Cipó, MG. We tested the relationship between species phenophases and local climate seasonality. We expect that the species phenophases are strongly correlated with variations of the dry and wet seasons. Observations were conducted monthly on reproductive (flowering, fruit production and dispersal) and vegetative (leaf fall and budding) phenophases. Given the combination of reproductive phenology, vegetative phenology, and seasonality, we observed four phenological strategies for the six species. Therefore this study revealed great diversity in phenological patterns, even when considering the small number of species sampled. Moreover, all species showed a significant seasonal pattern for the reproductive phenophases, with high concentrations of species reproducing during a given season, suggesting a key role of climate in defining phenological patterns in the campo rupestre grasslands.

Myrtaceae é uma das famílias mais representativas da flora brasileira, fato que não tem sido acompanhado por um número expressivo de trabalhos taxonômicos. O presente estudo teve como objetivo realizar o tratamento taxonômico para a família na Serra do Ouro Branco, o ponto mais ao sul da Serra do Espinhaço. Foram registrados 10 gêneros e 24 espécies para a região: Accara (1 sp.), Blepharocalyx (1 sp.), Calyptranthes (2 spp.), Campomanesia (2 spp.), Eugenia (2 spp.), Marlierea (2 spp.), Myrceugenia (2 spp.), Myrcia (10 spp.), Psidium (1 sp.), Siphoneugena (1 sp.). São apresentados chaves de identificação, descrições e comentários sobre gêneros e espécies.

This dissertation present an analysis of the interethnic conflict between Makuxi and Wapixana at the current moment in the Maloca of the Adobe, Aboriginal Land Fox-Mountain range of the Sun, in the State of Roraima. The theoretical field was boarded in the Ethnology, pursuing situations in local history, with edges in ethno-history. The research elapsed of the deepening necessity on the social relations and aboriginal politics, for the intercultural professional exercise of educator, appealing the bibliographical survey and participant comment as method; not directive interviews, photographs, filmings and daily register in of field, as techniques carried through in the period of 2006 to 2007. Although to inhabit in the same area and to establish marriages between itself, individuals and groups express tensions, aggravated with the landmark and legal recognition of the area, which generated inter dispute and intraetnias, mainly with the intrusion of farmers, rizicultores and the form of governmental influence. A relation of rivalry, individual and collective was evidenced, suggesting the strengthenig and not it fractionly, of the fights external politics, interns and in way to the cultural diversity and social adversity

O território da Serra da Lousã, quase desabitado e profundamente descaracterizado, esconde lugares em ruína e indícios de vivências passadas que a montanha teima em reclamar. Importa recuperar esses lugares reinventando-os, sob pena de se perderem com o passar do tempo e o avanço do meio natural. Este trabalho debruça-se sobre um dos lugares abandonados desta serra, a Silveira de Baixo, procurando nas suas raízes oportunidades para uma reactivação. Estuda a hipótese de tornar a aldeia e esta parte da serra, acessíveis a pessoas portadoras de deficiências, físicas ou cognitivas, tendo assim um duplo objetivo: permitir o acesso para todos a lugares de grande beleza natural e reactivar uma economia local que permita um desenvolvimento sustentado, através de actividades e produtos nativos deste território, conservando assim alguns dos seus saberes ancestrais. Desenha-se deste modo o início de uma comunidade, experimentando um equilíbrio entre o antigo e o contemporâneo, negando a musealização do lugar que o pode tornar estéril e constitui um impedimento no retorno de vida a este território. Assim, o trabalho experimenta o papel da arquitectura na reactivação de um lugar antigo e com marcas, preservando os seus elementos notáveis e com eles construindo novas espacialidades que ajudem ao estabelecimento de vivências contemporâneas; Mountain setlements: Proposal for reactivating an abandoned village in Ceira river valley, Lousã mountain range Abstract: The Lousã mountain range, almost uninhabited and profoundly decharacterized, speaks to us through its ruins about ways of living that ceased to exist. It is important to recover and reinvent them, otherwise they will slowly vanish as time goes by and nature steps in. This investigation focus on one of these abandoned settlements, Silveira de Baixo. It looks in its roots for opportunities of reactivation, investigating the hypothesis of turning this village and the mountain accessible to the physically and mentally impaired, thus assuming a double objective, of allowing these disabled people to experience a place of extreme beauty and of reinventing and reactivating native productive activities thus conserving them and allowing for the village’s economical sustainability. This work designs a new beginning for a community and experiments the balance between the old and the new, without excessive patrimonialisation that often kills the return of life to such settlements. Experimenting the role of architecture in providing life to an abandoned place through a sustainable intervention.
