Tinamou (Rhynchotus rufescens) is a native bird of the Brazilian fauna and has great potential to become a domesticated species. From this perspective, the objective of this study was to evaluate the carcass and main parts yield and to assess meat quality of that bird. Two trials, one studying stocking density and the other litter materials, lasting 60 days each, were conducted. The studied traits were evaluated in two birds/ replicate/treatment. Performance was evaluated by the least square method. The results showed that bird age at slaughter significantly influenced carcass and breast yields (p<0.05). Mean carcass, breast, thighs+drumstick and wing yields were 86.50±2.78%, 32.84±1.50%, 27.71±1.44%, and 13.21±0.94%, respectively. Shear force, pH, water holding capacity, lightness, redness and yellowness means and standard deviations were 1.92±0.98 kgf.cm-2, 6.07±0.12; 70±0.53%, 48.30±0.96, 1.96±1.01, and 1.61±1.0, respectively. Moisture, ash, crude protein, fat, and cholesterol contents were 72.35±0.16%, 1.12±0.06%, 25.53±0.50%, 0.17±0.01%, and 18.87±2.76 mg/10g, respectively. Results showed carcass and parts yields and the physicalchemical traits of tinamou meat are similar to chicken meat; however, tinamou meat is less acidic and has higher protein level combined with less calories and lower cholesterol levels.

In many human-modified tropical landscapes, biodiversity conservation and the provision of ecosystem services require large-scale restoration initiatives. Such initiatives must be able to augment the amount and the quality of remaining natural habitats. There is thus a growing need for long-term, multi-stakeholder and multi-purpose initiatives that result in multiple ecological and socioeconomic benefits at the biome scale. The Atlantic Forest Restoration Pact (AFRP) is a coalition of 260+ stakeholders, including governmental agencies, private sector, NGOs and research institutions, aimed at restoring 15 million ha of degraded and deforested lands by 2050. By articulating, and then integrating common interests, this initiative has allowed different sectors of society to implement an ambitious vision and create a forum for public and private concerns regarding forest restoration. The AFRP adopts a set of governance tools so multiple actors can implement key processes to achieve long-term and visionary restoration goals. Having overcome some initial challenges, AFRP now has to incorporate underrepresented stakeholders and enhance its efforts to make forest restoration more economically viable, including cases where restoration could be less expensive and profitable. The AFRP experience has resulted in many lessons learned, which can be shared to foster similar initiatives across tropical regions. © 2014 by the authors. Source

Archaeological gold mining structures from the Brazilian colonial period are present in Guarulhos and Mairiporã municipalities, São Paulo State, southeastern Brazil. These structures are represented by dams, tanks, paved and unpaved channels, water ducts, drains, gold mining fronts and benches, gravel refuse piles, stone walls, places to wash and seek gold, and remains of a water-powered iron engine, which have great archaeological, geological, and historical values, covering an area of several square kilometres. Gold was essentially mined in alluvial, colluvial, eluvial, and saprolitic material associated with rocks of the Mesoproterozoic Serra do Itaberaba Group that corresponds to a metamorphosed volcano-sedimentary sequence that outcrops in the central part of the Ribeira fold belt. Some structures are also associated with Neogene alluvial fan conglomerates and proximal alluvial fan mudstones of the Resende Formation within the Taubaté Group, denoting geological reworking processes of Mesoproterozoic gold. Gold mining archaeological structures from the municipality of Guarulhos are going to be preserved within the scope of the Gold Cycle Geopark that covers an area of 16,900 ha, which was created by Guarulhos' Municipal Decree No. 25974 of 16 Dec 2008, presently being implemented. However, resources must be obtained in order to recover structures, as well as to promote the construction of visiting frameworks in the places where these structures are present. © 2013 Springer-Verlag Berlin Heidelberg.

Application of analytic Hierarchy process in the construction of a fuzzy system to support the planning for future use in land reclamation: Case study of the pit mining in Serra do Japi [Aplicação do processo analítico Hierárquico na construção de um sistema fuzzy de apoio ao planejamento do uso futuro na recuperação de áreas degradadas: Estudo de uma cava mineral na Serra do Japi]

The definition of use future is fundamental to land reclamation. However, the selection among alternatives requires an integrated assessment through a structured and logic process. Thus, the aim of this paper is introduce a proposal to support the planning of future use, applied in a deactivated pit mining, in Serra do Japi, Jundiaí city, São Paulo state, Brazil. For that, a Fuzzy Inference System was elaborated, whose rule base was constructed from Analytic Hierarchy Process. Considering its relevance to self-sustainability, the forest connectivity, the area extension and the edge effect were selected as analysis criteria and the outputs being modeled as use recommendations, represented by revegetation and re-destination. As results, based on evaluated condition, its application in the study area recommended the revegetation, predominating influence of its good forest connectivity. Although, being a relatively small area and with a significant edge effect, the system pointed out a low confidence level in this recommendation. Therefore, it was considered a coherent output with the expected and a satisfactory reference to the decision maker accept or deny the recommendation given by the support system. © 2015, Universidade Estadual Paulista.
