A survey carried out by Action Pesquisas de Mercado, at the request of the Sustainable Amazon Foundation (FAS) and with the support of the Climate and Society Institute (ICS), shows that the overwhelming majority of the inhabitants of Manaus, the largest city in the Brazilian Amazon, are against deforestation and fires and favorable to the maintena...

Article
Natural ecosystems, including forest ecosystems, continue to be degraded or converted at an alarming rate. To complement or substitute regulatory approaches to ecosystem management, market-based instruments such as "payments for ecosystem services" (PES) have been introduced and are gaining popularity. One of the prominent PES schemes in the world...

"Reducing tropical deforestation is a major climate and development issue: forest clearing is responsible for roughly a fifth of greenhouse gas emissions, and the forest-dependent poor number over a billion. In the runup to the Copenhagen climate summit, REDD – reducing emissions from deforestation and (forest) degradation by providing incentives t...

"Deforestation accounts for roughly 17 per cent of global greenhouse gas emissions. So it is no surprise that in the runup to the December 2009 climate talks in Copenhagen, REDD – reduced emissions from deforestation and degradation – is emerging as a strategy with big potential for mitigating climate impacts. With REDD, local communities can be re...

O Programa Bolsa Floresta implementa uma série de atividades prioneiras no campo da conservação ambiental e desenvolvimento sustentável na Amazônia. Sua concepção se insere no contexto das mudanças climáticas globais e de redução do desmatamento, com especial ênfase para as comunidades tradicionais da "Amazônia profunda". Este artigo descreve o con...

RESUMO: No presente estudo foram estimados o potencial produtivo e a colheita sustentá- vel de Euterpe precatoria em áreas de florestas de Baixio e Terra Firme no Seringal Caquetá, na Amazônia Ocidental, Brasil. Além disso, foram feitas algumas recomendações para o bom manejo dos frutos. O potencial produtivo anual médio encontrado na floresta de B...

Forest structure and tree species composition were studied in four Atlantic seasonal forest fragments ranging from 0.7 to 220 ha, isolated for more than a century in southeastern Brazil. Four physiognomic units were recognized within these fragments: (1) low forest, (2) bamboo forest, (3) high forest, and (4) mature forest. Tree density, basal area...

This paper describes changes in richness, diversity and floristic composition of tree species of four forest eco-units ("low capoeira", "high capoeira type 1", "high capoeira type 2" and "mature forest") identified through the Rapid Ecological Assessment procedure in a semideciduous seasonal forest fragment of9.5 ha in Piracicaba region, São Paulo...

Para verificar a hipótese de que a fragmentação das florestas tropicais associada às perturbações antrópicas podem resultar numa maior perda de espécies arbóreas e na mudança na composição florística ao longo do tempo foi analisado um fragmento de floresta estacional semidecidual de 9,5 ha localizado na região de Piracicaba, Estado de São Paulo, on...

RESUMO: O desafio de conservar a biodiversidade regional em paisagens intensamente cultivadas tem como principal limitante o processo de degradação de fragmentos florestais. Tamanho, forma, grau de isolamento, tipo de vizinhança e histórico de perturbações apre-sentam relações com fenômenos biológicos e, conseqüentemente, afetam a dinâmica dos frag...

Artificial canopy gaps were made by felling trees in rain forest on Maracá Island. There were three replicates of each gap size: small (c. 40 m2), medium (c. 150 m2), large (c. 350 m2), very large (c. 2500 m2), and unfelled forest controls (2500 m2). Changes in microclimate, soil chemistry, and soil biological processes including decomposition were...

Three replicate artificial canopy gaps of four sizes (ca. 40 m2, ca. 150 m2, ca. 350 m2, and ca. 2500 m2) were made in rain forest on Maracá Island. Gaps were defined according to Brokaw (1982)and all vegetation (>2 m tall) within them was felled and left in place. The nine most numerous dicotyledonous tree (≥10 cm dbh) species of unfelled forest w...
Article
Ecological certification of forest products is a rapidly developing market-based incentive for better forest management. Improved forest management can be an important component of tropical conservation and development strategies. To provide a solid biophysical basis for certification programs, however, research is needed on the ecological and silv...

1. Maraca, Brazil, is a large riverine island which is at the boundary between lowland evergreen rain forest and savanna. The island is now uninhabited but there is evidence that much of its forest (including the plots described in this paper) is secondary, dating from before 1880. 2. The mean annual rainfall is about 2300 mm and there is a dry sea...

1. Introducción y Revisión de literatura Brasil posee el segundo mayor hato bovino del mundo, con cerca de 160 millones de cabezas. La actividad ganadera es un factor importante en el proceso de expansión de la frontera agrícola y, por lo tanto, del corte de árboles en larga escala. Actualmente cerca de millones de hectáreas son deforestadas anualm...
