this study was carried out to investigate the effective environmental factors in the distribution of vegetation in zirkouh rangelands of qaen. after delimitation of the study area, sampling of soil and vegetation were performed using randomized- systematic method. vegetation cover was recorded by using braun-blanquet combined abundance-cover scale in each sample. within each sample, one profile...

In this work, a demographic study of Gaultheria glomerata and Disterigma empetrifolium was carried out in the Indiviso sector Baquerizo Moreno parish, Píllaro canton, Tungurahua province. The vegetation analogous between montane forest shrubby moorland, located at coordinates 01°18'S; 78°30'W, altitude 3400 m.a.s.l., where Braun-Blanquet methodology for cover adapted by means plots, which were ...

Methionyl-tRNA synthetase has been purified from a yeast strain carrying the MESl structural gene on a high copy number plasmid (pFL1). The purified enzyme is a monomer of M, = 85,000 in contrast to its counterpart from Escherichia coli which is a dimer made up of identical subunits (M, = 76,000; Dardel, F., Fayat, G., and Blanquet, S . (1984) J. Bucteriol. 160,1115-1122). The yeast enzyme was ...

the aim of this research is to classification of soil seed bank in populus caspica protected area. the study of above ground vegetation and soil seed bank were carried out with braun-blanquet and seedling emergence method respectively. results showed that size of soil seed bank in upper layer (713 seeds per m2) were significantly lower than depth layer (1163 per m2) but species richness from 42...

The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013–2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-...

A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acac...

Detailed plant diversity information is lacking for Africa, as for many other regions in the tropics, therefore we have used our collection and observation databases to search for possible indicator groups. Digitization of specimen label data for Burkina Faso from the Herbarium Senckenbergianum (FR) and the Ouagadougou University Herbarium (OUA) led to a database containing 18 000 specimens. Fi...

Species diversity is one of the most important indices used for evaluating the sustainability of forest communities. This study aims to characterize the forest communities and to identify and compare the plant species diversity in the study area. For this purpose, 152 relevés were sampled by a randomized-systematic method, using the Braun-Blanquet scale. Classification of the vegetation was con...

The epiphytic bryophyte vegetation of the Kumbet Plateau (Dereli-Giresun) was investigated. A total 40 releves taken from tree trunks in different periods year 2019 were analysed using multivariate analysis methods such as detrended correspondence (DECORANA) and two-way indicator species (TWINSPAN), Braun-Blanquet method also applied. As a result, Frullanio tamarisci-Neckeretum pumilae Alata?, ...
