—Th e management of artifi cial hardwood stands suff ers from a paucity of information. As a result, many managers and scientists turn to conventional pine plantation management as a source for informing silvicultural decisions. Such an approach when managing hardwoods ignores the development occurring in natural hardwood stands, which produce stems prized for their growth and form. Contrary to...

Historically square or almost spacing design has been used in plantation forest, as it claimed to maximize productivity. In this study, based on field experiments established the mid-1980s, we tested effect of different rectangular planting designs (2 × 2, 1.33 3, 1 4, 0.8 5, 1.46 4 m) productivity, stand heterogeneity, and external wood properties three coniferous species: Scots pine, Lodgepol...

Differences in volatile terpene content of Pinus caribaea needles and soil qualities between two pine plantations (Uverito and Sartenejas) in Venezuela were analyzed. Soils in the Uverito pine plantation were sandy, low in nutritional quality, and deficient in available nitrogen and phosphorus content. Pines grown on these soils presented in their needles higher concentrations of alpha-pinene, ...

We investigated the influence of Pinus afforestation on the structure of leaf-litter ant communities in the southeastern Brazilian Atlantic Forest, studying an old secondary forest and a nearly 30 year-old never managed Pinus elliottii reforested area. A total of 12,826 individual ants distributed among 95 species and 32 genera were obtained from 50 1 m(2) samples/ habitat. Of these, 60 species...

Fifty-four plots in 33-43 year old longleaf pine plantations were compared to 30 remnant plots in longleaf stands on the Savannah River Site in South Carolina. Within these stands, the structure and composition of primarily the herb layer relative to a presumed soil moisture or soil texture gradient was studied using the North Carolina Vegetation Survey methodology. Data were also collected on ...

Ecological restoration with a multispecies and multifunctional approach can accelerate the re-establishment of numerous ecosystem services. The challenges land that is degraded, damaged, or destroyed post-mining are low productivity soil high potential for contaminants. Herein, we evaluated to strategy through mixture woody herbaceous species, microsymbiont biochar amendments, plant spacing. ex...

Plantation forests the world over have been established in order to supply industrial mills with wood. It is estimated that by 2050, over half of the world’s requirements for industrial timber could be supplied from plantations, thus reducing the pressure on natural forests. Ensuring that the plantation, with its many stands, different planted species, terrains, etc., delivers the correct volum...

In this study, we ask if instead of being fundamentally opposed, niche and neutral theories could simply be located at the extremes of a continuum. First, we present a model of recruitment probabilities that combines both niche and neutral processes. From this model, we predict and test whether the relative importance of niche vs. neutral processes in controlling community dynamics will vary de...

Sequential exchanges of vocalizations (staccatos and neighs) emitted by Northern Muriquis Brachyteles arachnoides hypoxanthus were recorded at the Biological Station of Caratinga, Minas Gerais State, Brazil. Staccatos and neighs containing larger proportion of short elements were preferentially produced during short-range exchanges; neighs, produced by a larger number of participants, were typi...
