Gaps created by falling trees (tree-fall gaps) are a natural disturbance in forest ecosystems. Understanding scale, pattern and the effect of gaps on regeneration is important to current and future forest management. The aim of this study was to determine the size, shape and the spatial pattern of tree-fall gaps and of associated regeneration. This study was carried out in three parcels (No.15,...

The study involved 286 patients (17-58 years, 55.9% females and 44.1% males). SPT was performed with extracts “Mixture of trees” (Diater Laboratorios, Spain). The study of allergen components was made by ImmunoCAP. We evaluated the efficiency of SLIT by visual analogue scale. 98.3% patients had positive SPT to extract “Mixture of trees”. N=281:191 (68.1%) individuals were positive to birch extr...

With the growing demands from a population expected to reach 9 billion people by 2050, it is unclear how our current global food system will meet future food needs. Ensuring that all people have access to adequate and nutritious food produced in an environmentally and socio-culturally sustainable manner is one of the greatest challenges of our time. ―Sustainable diets‖ have been proposed as a m...

In a northwestern Connecticut forest, we quantified the carbon (C) and nitrogen (N) content of the forest floor and the top 15 cm of mineral soil and the rate of midsummer net N mineralization beneath six different tree species. There were large interspecific differences in forest floor depth and mass, in the size and distribution of C and N pools at varying soil depths, and in rates of midsumm...

A quantitative evaluation of wood chemical components for some tree species in a forest area from east-northern Romania is presented here, through a comparative study from 1964 to 2000. Investigation upon the wood tree-rings in a Quercus robur L. tree species, as a dominant species, as regards its chemical composition and structure of the natural polymer constituents cellulose and lignin was al...

Five medicinal plants viz. Abelmoschatus moschatus Linn., Clitoria tematea L., Plumbagozeylanica L., Psorolea corylifolia L. and Withania sominifera L. were grown in a polypot experiment in five soils representing coal mine soil, coppermine soil, fly ash, skeletal soil and forest soil with and without mycorrhizal inoculations in a completely randomized block design. Dry matter yield and mycorrh...

1.1 Silenus Silenus (Mi et al., 2008; Mi and Huang, 2008) is a forest-based tree-to-string SMT system. A packed parse forest is a compact representation of all derivations (i.e., parse trees) for a given sentence under a context-free grammar. A tree-to-string rule describes the correspondence between a source parse tree and a target string. Unlike previous tree-to-string (Liu et al., 2006; Huan...

We examined tree species responses under forest harvesting and an increased fire disturbance scenario due to climate warming in northern Wisconsin where northern hardwood and boreal forests are currently predominant. Individual species response at the ecosystem scale was simulated with a gap model, which integrates soil, climate and species data, stratified by ecoregions. Such responses were qu...
