1. Future uncertainties for the distribution and conservation of Paubrasilia echinata under climate change
ABSTRACT Paubrasilia echinata is a widely cultivated endangered tree species with small populations restricted to a narrow strip of habitats along the Brazilian coast. The potential impacts of climate change on the distribution of P. echinata have yet to be investigated, and so it remains unknown whether protected areas will ensure the persistence of the spe

3. The rarest of the rare: rediscovery and status of the critically endangered Belem Curassow, Crax fasciolata pinima (Pelzeln, 1870)
Abstract The Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sightings of birds in the wild for 40 years. This subspecies is nationally and internationally classified as critically endangered and close to extinction, suffering from poaching and deforestation in its range. Here we present new records of fr

4. Influence of artificial lights on the orientation of hatchlings of Eretmochelys imbricata in Pernambuco, Brazil
ABSTRACT Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following the moonlight’s reflection in the ocean. Increased human activities such as tourism and artificial lights on the coasts, however, have interfered with the ability of sea turtle neonates to find their correct destination, neg

5. Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles
ABSTRACT Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order

6. Identifying forest ecosystem regions for agricultural use and conservation
ABSTRACT Balancing agricultural needs with the need to protect biodiverse environments presents a challenge to forestry management. An imbalance in resource production and ecosystem regulation often leads to degradation or deforestation such as when excessive cultivation damages forest biodiversity. Lack of information on geospatial biodiversity may hamper f

7. Consequences of suppressing natural vegetation in drainage areas for freshwater ecosystem conservation: considerations on the new "Brazilian forest code"
The input of particulate and dissolved organic matter (POM and DOM, respectively) from terrestrial ecosystem drainage basins is an important energy and nutrient source in limnic food chains. Studies indicated that semi-deciduous seasonal forests located in drainage areas in Brazil have the potential to produce 7.5 - 10.3 Mg ha−1/year of POM. The global inc

8. A relevância das unidades de conservação na proteção de espécies arbóreas ameaçadas de extinção da Mata Atlântica do Sudeste da Bahia / The relevance of conservation units for the protection of tree species threatened by extinction from Atlantic Forest of Southeast of Bahia
A Floresta Atlântica do sudeste da Bahia apresenta uma das maiores riquezas de espécies arbóreas por área do planeta, com uma significativa porcentagem endêmica. Essas espécies encontram-se altamente ameaçadas pelos elevados índices de desmatamento, fragmentação de habitat e corte seletivo decorrente na região. As Unidades de Conservação têm ,

9. Análise dos fatores intervenientes no cumprimento das normas referentes às reservas legais no Estado de São Paulo / Analyse of determinants of compliance with the rules referent to legal reserves in São Paulo State
Legal Reserve Forest, instituted by the Brazilian Forest Code (Law 4.471/1965), requires that each rural properties in national territory must have a patch of native vegetation in their land. Despite the importance for nature conservation has been recognized, until today the LR it has not been fully implemented. The present study aim to investigate the facto

10. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

From the 1930s Brazil created many laws to protect the natural resources. But with the implantation of incentive programs which aim the economic growth at any cost, with modern farming practices and the expansion of agriculture and cattle raising, great losses occurred to the preservation and conservation of the natural resources. The driving question for th

12. Diversidade de macrófitas aquáticas em áreas úmidas do Parque Nacional da Lagoa do Peixe, Rio Grande do Sul
The Lagoa do Peixe National Park is an important conservation unity, aiming to protect the wetlands, one of the most endangered type of ecosystem in the world. In Southern Brazil around 90% of the wetlands were already lost. The protected ecosystems in the park are ernationally important for biodiversity conservation and it is the unique Ramsar site in South
