Os Campos de Altitude do sul do Brasil são formados por comunidades vegetais herbáceas e arbustivas desenvolvidas sobre solo raso e rochoso, estando restritos a serras de altitudes elevadas, onde predomina clima subtropical ou temperado. Constituem uma vegetação relictual marcada por endemismos. O objetivo deste trabalho é caracterizar Campos de Altitude na região do Campo dos Padres, Bom Retiro/Urubici, SC. A área estudada possui 4.900 ha, localiza-se nas bordas da Serra Geral, abrangendo altitudes de 1.500 a 1.827m. Amostrou-se a vegetação através do método do caminhamento, resultando em 214 espécies distribuídas em 48 famílias. As com maior riqueza de espécies foram Asteraceae (50 espécies), Poaceae (32) e Cyperaceae (19), que contribuem também em grande número de indivíduos para caracterizar a fisionomia dos campos. Classificou-se a vegetação através da interpretação visual da imagem dosatélite SPOT 4, com auxílio da composição florística dominante verificada in loco. Informações geográficas, descrições da paisagem e registros fotográficos foram organizados em banco de dados. Gerou-se mapa temático de unidades de paisagem com classes de fitofisionomia campestre: campo úmido, campo herbáceo e campo arbustivo e; de fitofisionomia não-campestre: floresta, vegetação de escarpa e silvicultura. Encontrou-se proporção semelhante de cobertura vegetal campestre (46,1%) e florestal(46,5%). Das unidades de paisagem campestre, 783 ha são de campo úmido, 1.145 de campo herbáceo e 330 de campo arbustivo, sendo apontadas também unidades fitoecológicas não detectáveis na imagem de satélite: turfeira e banhado. A paisagem é composta por um mosaico de tipologias vegetacionais, caracterizada por diferentes comunidades climáticas, edáficas e seres sucessionais. Interferências antrópicas, taiscomo desmatamento, pecuária extensiva e queimadas dificultam a delimitação de campos naturais. Constatou-se a existência de campos antrópicos em sucessão secundária (decorrentes da derrubada de floresta), campos naturais em sucessão primária (sob avanço florestal associado às condições climáticas atuais) e campos naturais secundários (estágio médio a avançado, pois submetidos à pastoreio de baixa intensidade e queimadas). Evidências apontam que o fogo mantém a condição campestre atual, impede o avanço florestal sobre os campos, marca transições abruptas entre campos e florestas e reduz florestas já consolidadas. O acompanhamento da evolução dos campos na ausência de interferências antrópicas constitui oportunidade ímpar para o entendimento da ecologia dos Campos de Altitude. A curto prazo, áreas de turfeiras, banhados e poucas de campo herbáceo parecem não sujeitas ao avanço das formações arbustivo-arbóreas.

This reference work provides a comprehensive overview of bioactive compounds investigated in bryophytes and pteridophytes and explores their nutritional, biological, pharmacological and ecological effects. Bryophytes are cosmopolitan lower plants that are rich in phytochemicals including fatty acids, tocopherols, phenolics, terpenoids. Additionally, these plants contain bibenzyls, bis-benzyls, and polyketides which have been demonstrated to have antimicrobial, anti-inflammatory, and cytotoxic activities. Pteridophytes are another group of lower vascular plants which were reported to have useful secondary compounds such as flavonoids, steroids, phenolics, terpenoids, and these plants impart medicinal values including antioxidant, antimicrobial, anti-inflammatory, anti-tumor, and anti-HIV activities. This book contains comprehensive contributions compiled by expert scientists and researchers in this field.The book offers a useful resource for plant biotechnologists, plant biologists, pharmacologists, pharmacists, food technologists, nutritionists, research investigators of the healthcare industry, academia, faculty, and students of biology and biomedical sciences. It also provides a strategic framework for further research and development activities of bryophytes and pteridophytes of the world.

Agamben charts a journey that ranges from poems of chivalry to philosophy, from Yvain to Hegel, from Beatrice to Heidegger. An ancient legend identifies Demon, Chance, Love, and Necessity as the four gods who preside over the birth of every human being. We must all pay tribute to these deities and should not try to elude or dupe them. To accept them, Giorgio Agamben suggests, is to live one's life as an adventure—not in the trivial sense of the term, with lightness and disenchantment, but with the understanding that adventure, as a specific way of being, is the most profound experience in our human existence. In this pithy, poetic, and compelling book, Agamben maps a journey from poems of chivalry to philosophy, from Yvain to Hegel, from Beatrice to Heidegger. The four gods of legend are joined at the end by a goddess, the most elusive and mysterious of all: Elpis, Hope. In Greek mythology, Hope remains in Pandora's box, not because it postpones its fulfillment to an invisible beyond but because somehow it has always been already satisfied. Here, Agamben presents Hope as the ultimate gift of the human adventure on Earth.

Heir to one of the world's largest fortunes, member of the U.S. American Republican party's liberal wing, Nelson Aldrich Rockefeller served as Governor to the state of New York for four consecutive terms, as Vice President of the United States under Gerald Ford after Richard Nixon's resignation, all while remaining eternally desirous of the Yankee Republic's foremost position. Yet what remains in this flavorful profile is his biography's least-known facet: as propulsor of capitalism in Brazil. Rockefeller got closer to the country during his time as chair of the U.S. office for Inter-American Affairs, a government organ which strove to distance the Vargas Administration from Nazism and Fascism and to guarantee that Brazil would remain under the aegis of the U.S. American influence. With tenacity, "good intentions," and having been imbued with the ideologies of his nation and class, the politician manifested genuine interest in Brazil, and involved himself in the most varied of activities, from rubber cultivation to São Paulo's urban planning, always attempting to import efficiency and the American Way of Life as an antidote preventing the expansion of communism.THE AMERICAN "AMIGO" is another book by Antonio Pedro Tota, author of O Imperialismo Sedutor (The Seduction of Brazil) and O Amigo Americano.

For the ruling and propertied classes of the late eighteenth century, the years following the French Revolution were characterized by intense anxiety. Monarchs and their courtiers lived in constant fear of rebellion, convinced that their power-and their heads-were at risk. Driven by paranoia, they chose to fight back against every threat and insurgency, whether real or merely perceived, repressing their populaces through surveillance networks and violent, secretive police action. Europe, and the world, had entered a new era. In Phantom Terror, award-winning historian Adam Zamoyski argues that the stringent measures designed to prevent unrest had disastrous and far-reaching consequences, inciting the very rebellions they had hoped to quash. The newly established culture of state control halted economic development in Austria and birthed a rebellious youth culture in Russia that would require even harsher methods to suppress. By the end of the era, the first stirrings of terrorist movements had become evident across the continent, making the previously unfounded fears of European monarchs a reality. Phantom Terror explores this troubled, fascinating period, when politicians and cultural leaders from Edmund Burke to Mary Shelley were forced to choose sides and either support or resist the counterrevolutionary spirit embodied in the newly-omnipotent central states. The turbulent political situation that coalesced during this era would lead directly to the revolutions of 1848 and to the collapse of order in World War I. We still live with the legacy of this era of paranoia, which prefigured not only the modern totalitarian state but also the now preeminent contest between society's haves and have nots. These tempestuous years of suspicion and suppression were the crux upon which the rest of European history would turn. In this magisterial history, Zamoyski chronicles the moment when desperate monarchs took the world down the path of revolution, terror, and world war.
