The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon(1-3). With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses(4-9). As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world's major tropical regions. Our analysis reveals great variation in reserve `health': about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.

Esta dissertação tem como proposta fazer uma análise da produção maquínica de subjetividade do programa Globo Esporte, da TV Globo, e de suas variações enquanto gênero; além de discutir a influência do noticiário no comportamento de parte do público-alvo. Para tanto, partiu-se dos conceitos filosóficos de pensadores como Gilles Deleuze, Félix Guattari, Michel Foucault, Antônio Negri, Michael Hardt e Peter Pál Pelbart, entre outros, e das observações referentes ao processo comunicacional de Pierre Bourdieu, Muniz Sodré, Edgar Morin e Joseph Campbell, como ainda da sociologia do esporte através de Ronaldo Helal e Hugo Lovisolo. A produção de subjetividade, a presença do ídolo esportivo, a territorialização imposta dos mass-media, os focos de resistência encontrados na multidão são algumas questões debatidas nesta dissertação, que contou com a elaboração de um dispositivo composto por uma série de etapas, no qual, com a ajuda de grupo focal, pode-se melhor compreender a dinâmica da relação: telejornalismo esportivo - produção do ídolo-torcedor/telespectador.
