| An annotated list of the free-living insect herbivores collected on the seedlings of five rainforest tree species of economic importance near Mabura Hill, Guyana, is presented. The host plants were Chlorocardium rodiei (Scomb.) (Lauraceae), Mora gonggrijpii (Kleinh.) Sandw. (Caesalpiniaceae), Eperua rubiginosa Miq. (Caesalpiniaceae), Pentaclethra macroloba (Willd.) Kuntze (Leguminosae,) and Catostemma fragrans Benth. (Bombacaceae). During the monitoring of approximately 10,000 seedlings at monthly intervals during two years, 27,735 insect individuals were collected representing 604 species. Leaf-chewing insects were further tested in captivity, to remove transient and non-feeding species. The most common higher taxa included Psyllidae, Cicadellinae,... |

| Brazil will benefit if it gains control of its vast Amazonian timber resources. Without immediate planning, the fate of much of the Amazon will be decided by predatory and largely unregulated timber interests. Logging in the Amazon is a transient process of natural resource mining. Older logging frontiers are being exhausted of timber resources and will face severe wood shortages within 5 yr. The Brazilian government can avoid the continued repetition of this process in frontier areas by establishing a network of National Forests (Florestas Nacionais or Flonas) to stabilize the timber industry and simultaneously protect large tracts of forest. Flonas currently comprise less than 2% of the Brazilian Amazon (83,000 km2). If all these forests were used for... |

| There is consensus that payments for biodiversity services are a promising conservation tool, yet the implementation of applied schemes has been lagging behind. This paper explores some reasons why potential biodiversity buyers may hesitate. It describes the case of an unsuccessful attempt to establish a community conservation concession in the village of Setulang (East Kalimantan, Indonesia) to safeguard a biologically valuable area from predatory logging. Potential biodiversity donors did not engage in this payments-for-environmental-services scheme mainly because of their limited time horizon and uneasiness about the conditionality principle. Other complicating factors included overlapping land claims, and the diagnosis of the externality at hand. We... |

| Community forests and protected areas have each been proposed as strategies to stop deforestation. These management strategies should be regarded as hypotheses to be evaluated for their effectiveness in particular places. We evaluated the community-forestry hypothesis and the protected-area hypothesis in community forests with commercial timber production and strict protected areas in the Maya Forest of Guatemala and Mexico. From land-use and land cover change (LUCC) maps derived from satellite images, we compared deforestation in 19 community forests and 11 protected areas in both countries in varying periods from 1988 to 2005. Deforestation rates were higher in protected areas than in community forests, but the differences were not significant. An... |

| Por meio de procedimentos e técnicas de restauração que considerem a escolha apropriada das espécies (principalmente quanto às características econômicas e ambientais), florestas exauridas de espécies comerciais podem ser conduzidas de maneira a reverter, ou minimizar, os efeitos da exploração seletiva que modificou sua estrutura original. Além disso, é fundamental que a condução posterior aos procedimentos de restauração seja feita de modo a garantir a sustentabilidade das espécies em florestas de produção. Este trabalho objetiva descrever os métodos utilizados, as etapas iniciais de implantação, a definição de espécies aptas e os resultados preliminares de plantios de enriquecimento com espécies florestais madeireiras de alto valor comercial em áreas de... |

| A exploração florestal convencional infelizmente tem objetivos de curto prazo. O resultado final é uma diminuição da área útil de manejo com possibilidades de regeneração. Normas que contemplam uma intervenção de baixo impacto, em povoamento de floresta nativa, podem garantir uma maior certeza na sustentabilidade do manejo florestal. Os objetivos principais deste trabalho são lembrar e sugerir uma série de procedimentos de forma organizada que possibilite o manejo florestal de baixo impacto, em determinada área, de forma financeiramente viável e monitorada. O menor dano ambiental, aliado aos baixos custos, é fundamental para a viabilidade do manejo florestal. |
