The high species richness can be attributed to the existence of a varied set of natural and artificial freshwater biotopes, placed in distinct physiographic contexts along a contact zone between Brazil's Atlantic Forest and Cerrado hotspots. This area figures as a priority site for biodiversity conservation in the State of Minas Gerais, and in 2004 became Brazil's first protected area dedicated to the conservation of odonates and their freshwater habitats.

For some stakeholders, however, compliance with these criteria may seem complex, costly, or unfeasible. What exiting tools, then, might facilitate compliance with a variety of biofuelrelated sustainability criteria? This paper presents four existing tools and methodologies that can help stakeholders assess (and mitigate) potential risks associated with feedstock production, and can thus facilitate compliance with requirements under diVerent requirement systems. These include the Integrated Biodiversity Assessment Tool (IBAT), the ARtiWcial Intelligence for Ecosystem Services (ARIES) tool, the Responsible Cultivation Areas (RCA) methodology, and the related Biofuels + Forest Carbon (Biofuel + FC) methodology.

In this study we experimentally reproduced these traditional management practices upon a natural population of the starflower Comanthera elegantula (Ruhland) L.R. Parra & Giul. (Eriocaulacece) using eight distinct treatments consisting of 'fire', "harvest" and the combined absence of these interventions over two years, in order to assess their effects on seedling recruitment. The study was conducted at the central Espinhaç o range region, in Minas Gerais State, Brazil. Our results show that the extractive management practices interfere with the recruitment dynamics of C. elegantula, with fire significantly reducing the competing herbaceous cover and stimulating seedling recruitment. An intermittent fire regime seem to favor seedling establishment and growth, while sequential fire episodes seem to negatively impact the progression of seedling cohorts and the regrowth of the herbaceous cover. Additional seed input took place at local scale, probably through dispersion from outer sources and/or from seed banks. Seed pool depletion isto be expected under a persistent and efficient inflorescence collection regime and may ultimately contribute to population senescence.

Until recently, the only known colonies of P. burchellanus were located in the municipalities of Brumadinho, in Minas Gerais state, and Planaltina, in the Distrito Federal, some 640 km apart from each other. The implications of these new records to the conservation status of this species are discussed.

Less than 100,000 km 2 (about 7%) of the forest remains. In some areas of endemism, all that is left are immense archipelagos of tiny and widely separated forest fragments. In addition to habitat loss, other threats contributing to forest degradation include the harvesting of firewood, illegal logging, hunting, plant collecting, and invasion by alien species-all despite the legislation that exists for the forest's protection. More than 530 plants and animals occurring in the forest are now officially threatened, some at the biome level, some throughout Brazil, and some globally. Many species have not been recorded in any protected areas, indicating the need to rationalize and expand the parks system. Although conservation initiatives have increased in number and scale during the last two decades, they are still insufficient to guarantee the conservation of Atlantic Forest biodiversity. To avoid further deforestation and massive species loss in the Brazilian Atlantic Forest, the challenge is to integrate the diverse regulations, public policies, new opportunities, and incentive mechanisms for forest protection and restoration and the various independent projects and programs carried out by governments and nongovernmental organizations into a single and comprehensive strategy for establishing networks of sustainable landscapes throughout the region.

The dam failed on 5 November 2015, releasing tailings into the Rio Doce watershed and causing an environmental disaster in a biodiversity hotspot. To guide conservation action following the event, Brazilian authorities demanded an impact assessment focused on terrestrial species threatened by extinction. Postdisaster impact assessment is substantially more challenging than predevelopment impact assessment. Predisaster baseline data were sparse, and much was unknown about how the Fundão dam failure impacted terrestrial species threatened with extinction. Baseline reconstruction and impact pathway validation and characterization was critical. Ecosystem reconstruction revealed that 1580 ha of terrestrial ecosystems were destroyed, including approximately 480 ha of Atlantic rainforest. Collaboration with local experts identified 346 specie...

However, adaptation and mitigation activities tend to be approached separately due to a variety of technical, political, financial, and socioeconomic constraints. Here, we demonstrate that many tropical agricultural systems can provide both mitigation and adaptation benefits if they are designed and managed appropriately and if the larger landscape context is considered. Many of the activities needed for adaptation and mitigation in tropical agricultural landscapes are the same needed for sustainable agriculture more generally, but thinking at the landscape scale opens a new dimension for achieving synergies. Intentional integration of adaptation and mitigation activities in agricultural landscapes offers significant benefits that go beyond the scope of climate change to food security, biodiversity conservation, and poverty alleviation. However, achieving these objectives will require transformative changes in current policies, institutional arrangements, and funding mechanisms to foster broad-scale adoption of climate-smart approaches in agricultural landscapes.

We argue that in established mosaic landscapes including old cacao production regions where natural forest has already been reduced to relatively small fragments, a combination of both strategies is needed to conserve biodiversity. After reviewing the evidence for the insufficiency of either strategy alone if applied to such landscapes, the paper focuses on the cacao production landscape of southern Bahia, Brazil,
