| The fruits of the palm Butia capitata are harvested from wild populations. A lack of knowledge of their ecology has hindered the establishment of sustainable management practices. We investigated fruit biometric parameters, yield and phenology in two populations of B. capitata in the cerrado (savanna) in the north of the state of Minas Gerais, Brazil, at two study sites: in the communities of Mirabela (Fazenda Baixa site, studied from December 2006 through December 2007) and Campos (studied throughout 2007). Overall, adult palms produced an annual average of 7.6 leaves. At the Fazenda Baixa site, the mean annual number of infructescences was 4.9, compared with only 1.6 at the Campos site, and the annual yield was 197-373 and 145-468 fruits per tree (in... |

| ABSTRACT We studied the population structure and fruit availability of the babassu palm, Attalea speciosa, in three human-dominated landscapes located near a rural community in the region of Araripe, in the Northeast Region of Brazil, that were under intense fruit harvest. Fifty 10 x 10 m plots were randomly established in each of the three landscapes, and all individuals of A. speciosa within the plots were classified as seedlings, juveniles or adults, with the height of all adult individuals being measured. An additional 20 individuals were marked in each landscape, and the number of total bunches, fruits per bunch and bunches per palm tree were recorded. The populations of A. speciosa in the three landscapes exhibited an inverted J-shape plot, but... |

| In the mega-diverse country Peru, a resource intensive development model collides with the interest of conserving biodiversity. Peruvian biodiversity experts have developed different lines of argumentation as to how to integrate conservation into the sustainable development of their country. Applying grounded theory, I define five groups of conservation narratives based on the analysis of 72 qualitative interviews with experts working in areas of biodiversity conservation. I have labeled them: biodiversity protectionists, biodiversity traditionalists, biodiversity localists, biodiversity pragmatists, and biodiversity capitalists. These groups are each discussed in connection with what they have to say about biodiversity in relation to human life,... |

| O objetivo principal deste trabalho foi estimar custos e lucro líquido nas etapas de campo (incluindo a elaboração de cera de origem) do extrativismo da carnaúba. A coleta dos dados ocorreu ao longo dos anos de 2005 e 2006, por meio de entrevistas abertas e observação de campo, ocasião em que se realizou um diagnóstico amplo do setor. A motivação para esta empreitada é decorrente das dificuldades de obtenção de informações sistematizadas para respaldar cálculos de custos de produção, rentabilidade e lucratividade. Observou-se que a escolha feita pelo produtor na contratação dos serviços em campo implica diretamente no resultado final em termos econômicos, com variações significativas para mais e para menos no lucro final. Nas condições atuais de... |

| ABSTRACT Soluble solids (SS), titratable acidity (TA), SS/TA ratio, pH, moisture, soluble sugars (SSU), total reducing sugars (RSU), and non-reducing sugars (NRS) were assessed in the pulp of pequi fruits collected at three ripening stages: from the plant, from the ground after naturally falling off, and collected from the ground three days after naturally falling off. The evaluation was performed after six months of freezer storage both for fruits subjected to quick freezing (liquid nitrogen followed by freezer) and slow freezing (straight into the freezer). The variables assessed were not influenced by the freezing method. The SS, TA, and RSU contents increased with the ripening stage, suggesting that the fruits collected from the plant are still... |
