| The objective was to evaluate a reforestation carried out by the goldwashers. The studied area is situated along the Gualaxo do Norte river margins in Mariana - MG. The seedlings were received by donation of regional nurseries and were planted on December of 2006 in hole of 25x25 cm and plant spacing 3x2 meters. The evaluations were carried through on March of 2007. The height was measured with metric ribbon and the diameter, 5 cm above the ground, was done by using digital pachymeter. They planted 538 seedlings of 20 different species, pertaining to twelve botanical families. The most abundant species were Enterolobium contortisiliquum (96), Mimosa schomburgkii (76) and Chorisia speciosa (45). It was not possible to identify 19 individuals due to... |

| Forest transitions (FT) occur when socioeconomic development leads to a shift from net deforestation to reforestation; these dynamics have been observed in multiple countries across the globe, including the island of Puerto Rico in the Caribbean. Starting in the 1950s, Puerto Rico transitioned from an agrarian to a manufacturing and service economy reliant on food imports, leading to extensive reforestation. In recent years, however, net reforestation has leveled off. Here we examine the drivers of forest transition in Puerto Rico from 1977 to 2000 at two subnational, nested spatial scales (municipality and barrio) and over two time periods (1977-1991 and 1991-2000). This study builds on previous work by considering the social and biophysical factors that... |

| Plants of six species from the Melastomataceae family (Miconia spp. and Bellucia spp.) taken from secondary forest stands of Terra Firme near Manaus, Amazonas, Brazil, were studied with regard to growth form, biometric traits of the plants, morphological and anatomical characteristics of leaves and wood. In addition, plant biomass and the content of mineral nutrients of different parts of the plants were analysed, and xylem flux measurements were carried out to determine the specific water uptake of the plants. The aim of the studies was to detect causal links between the parameters measured and the ecological behaviour of the species as observed in the field, in order to provide an autecological description of the species. The results show that the plant... |

| ABSTRACTHigh concentrations of copper (Cu) may be toxic to plants, yet some species can be tolerant to soils contaminated by this metal. The study aimed to evaluate Cu translocation and tolerance in seedlings of ‘timbaúva’ (Enterolobium contortisiliquum (Vell.) Morong), ‘pata-de-vaca’ (Bauhinia forficata Link) and ‘amendoim-bravo’ (Pterogyne nitensTul) subjected to Cu-contaminated soil. The study was conducted in a greenhouse for 120 days, using as substrate a clayey Oxisol. The experiment was set in a completely randomized design, using a 3 x 6 factorial scheme, corresponding to three forest species (‘timbaúva’, ‘pata-de-vaca’ and ‘amendoim-bravo’) and six Cu doses in the soil (0, 60, 120, 180, 240 and 300 mg kg-1), with six replicates. The following... |

| The spatial distribution of insects is essential to perform control strategies, to improve sample techniques and to estimate economic losses. We aimed to determine the spatial distribution of nests of Acromyrmex crassispinus (Forel) in Pinus taeda plantations. The experiments were carried out in P. taeda plantations with different ages (treatments: recently-planted, three and six-year old plants). The study took place in Rio Negrinho and in Três Barras, SC. Three plots of one hectare were delimited in each treatment, and plots were divided in 64 sample units. The analysis of the dispersion index [variance/mean relationship (I), index of Morisita (Iδ) and k exponent of negative binomial distribution] showed that the majority of the samplings presented... |

| RESUMO: O objetivo deste trabalho foi avaliar o efeito do plantio de eucalipto nos teores de nutrientes e de carbono orgânico do solo em comparação com uma área virgem de Cerrado. Foram coletadas e analisadas amostras de solo até 1 m de profundidade em um experimento de procedências de Eucalyptus camaldulensis e em uma área adjacente de Cerrado, na mesma posição topográfica, em Planaltina, Distrito Federal. O solo é Latossolo Vermelho, argiloso (55% de argila, 23% de silte, 2% de areia grossa e 20% de areia fina) e distrófico. Na ocasião do plantio, o eucalipto foi adubado com 40 g de sulfato de amônio, 60 g de superfosfato triplo, 20% decloreto de potássio, 2 g de sulfato de zinco, 3 g de bórax e 500 g de calcário dolomítico por cova.

| Homogeneous forests are susceptive to the occurrence of population’s boom of forest pests. Among them, the beetles are considered important economically, not only for the actual damages to the stand, but mainly for the difficulty of control. This work aimed to carry out a population survey of insects, mainly of xylophagous, in stands of Tectona grandis. Twenty ethanolic traps and 30 wood samples of teak were installed in two stands in the municipalities of Alegre and Cachoeiro de Itapemirim, located in the south of Espírito Santo State, Brazil. After 18 months (January of 2011 to July of 2012) adult insects, pupas and larvae in the existing galleries in wood samples were collected. The collections of the adult insects were carried out monthly in the... |

| Forest Landscape Restoration (FLR) involves the ecological restoration of degraded forest landscapes, with the aim of benefiting both biodiversity and human well-being. We first identify four fundamental principles of FLR, based on previous definitions. We then critically evaluate the application of these principles in practice, based on the experience gained during an international, collaborative research project conducted in six dry forest landscapes of Latin America. Research highlighted the potential for FLR; tree species of high socioeconomic value were identified in all study areas, and strong dependence of local communities on forest resources was widely encountered, particularly for fuelwood. We demonstrated that FLR can be achieved through both... |
