Aims : The Braun-Blanquet approach has been widely implemented to generate classification schemes at the country level and Chile is not an exception. In spite of numerous studies, a revised system for whole still missing most current surveys are restricted small set vegetation groups or specific study sites. To fill this gap, we established vegetation-plot database updated into single syntaxono...
Abstract This study provides the first contribution to knowledge of non-calcareous grasslands arenaceous sector Monti Sibillini National Park (central Italy). We conducted 55 relevés using Braun-Blanquet phytosociological method and analysed ecology plant communities by Redundancy analysis topographic variables Ellenberg Indicator Values as predictors. identified nine communities, belonging fou...
The flora of willow (Salix viminalis L.) plantations consists various plant groups, including plants related to arable land, called segetal plants. Knowledge this is important for maintaining biodiversity in agroecosystems. aim the study was assess central Poland, depending on land use before establishment (arable or fallow) and age plantations. Moreover, also check presence invasive, medicinal...
A classification system of the Colchic spruce-fir forests (the Western Caucasus) was developed using Brawn-Blanquet method. Two new associations Dryopterido caucasicae–Abietetum nordmannianae ass. nov., Pruno laucerasi–Abietetum nov. and alliance caucasicae–Abietion all. were proposed after comparative syntaxonomic analysis dark coniferous from Euxine province. Diagnostic species are Acer pseud...
The present study identifies the hot spot of Yenice and aims to determine tree diversity in Fagus-Abies, Fagus Quercus-Fagus forests, define microbial community these forests by Biolog-Ecoplate method reveal physiological profile differences at level between forests. Accordingly, soil samples were taken from predefined different communities was analyzed using Biolog EcoPlate method. In addition...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...

The aim of this study was to investigate the relationship between physical and chemical properties of soils with vegetation distribution in Divan-Darre rangeland as one of the most important rangelands in Kurdistan province. For this purpose, a random systematic 150 m × 200 m gird sampling plan was used to establish 90 sampling plots. In each plot, soil factors and percent cover of each plant s...
