| Phytophagous mites from natural vegetation have been scarcely studied in Venezuela. Surveys were carried out from March 2007 to November 2008 to determine diversity of phytophagous mites inhabiting in different plant taxa in Iribarren, Jiménez, Palavecino, Morán and Crespo municipalities from Lara state, Venezuela. In each sampling site, a 500 m- transect was established and the most frequent plant species were sampled. In field, 15 leaves were examined for mite presence by using hand lens. In laboratory, plant material was examined under magnification and mite morpho-species belonging to tetranychid and tenuipalpid were picked up. A total of two tenuipalpid species and eight tetranychid species were identified. Tenuipalpid mites identified were... |

| Farmers’ practices in the management of agricultural landscapes influence biodiversity with implications for livelihoods, ecosystem service provision, and biodiversity conservation. In this study, we examined how smallholding farmers in an agriculture-forest mosaic landscape in southwestern Ethiopia manage trees and forests with regard to a few selected ecosystem services and disservices that they highlighted as “beneficial” or “problematic.” Qualitative and quantitative data were collected from six villages, located both near and far from forest, using participatory field mapping and semistructured interviews, tree species inventory, focus group discussions, and observation. The study showed that... |

| The role of community-based natural resources management in the form of “greening” after large scale system shocks and surprises is argued to provide multiple benefits via engagement with living elements of social-ecological systems and subsequent enhanced resilience at multiple scales. The importance of so-called social-ecological symbols, especially the potent hybrid symbols of trees and their handling after a disaster is interrogated. The paper explores the notion of hybridity, and applies it to the hybrid symbol of the tree in postdisaster contexts. The paper briefly highlights three U.S. cases documenting the symbolic roles of trees in a context of significant shock to a social-ecological system: the terrorist attacks on New... |

| RESUMO: A adição de nutrients pode aumentar a chance de sucesso dos plantios de recuperação de áreas degradadas, entretanto, existem poucos estudos sobre os efeitos da fertilização de espécies nativas do Bioma Cerrado. Este trabalho objetivou determinar o efeito sobre o crescimento e a sobrevivência de mudas de aroeirinha, na ausência de nitrogênio e a doses de 10, 20 e 40 kg/ha de N (uréia) e na ausência de fósforo e a doses de 10, 20 e 40 kg/ha de P (superfosfato triplo), plantadas em Latossolo Vermelho-Amarelo, ocupado com pastagem de Brachiaria decumbens. Foi avaliado o diâmetro do colo aos 4, 8 e 12 meses após o plantio e ao final do primeiro ano; o diâmetro de copa, a sobrevivência e a concentração foliar de nutrientes, Al e Na. A sobrevivência não... |

| As florestas tropicais estão entre os ecossistemas mais complexos conhecidos. Apesar da aparente desordem de seus componentes, encontram-se padrões mensuraveis de dinamica, composicao e estruturas. enquanto estes, entre outros aspectos, detalham riqueza e diversidade floristica, indicadores físicos da massa arborea e ocupação horizontal e vertical do espaço, em termos de dinamica, destacam-se, mortalidade e o crescimento da massa arborea. |
