This study aimed to analyse and evaluate the land suitability for certain fruit trees in Thuy Bang commune using GIS techniques in combination with a multi-criteria approach. At first, the databases for GIS analyses had to be developed. The data were obtained through scientific literature review, expert opinions, interviews, and professional officers. The suitability assessment in the studied a...
To increase the understanding of lake sturgeon (Acipenser fulvensens) in the upper Mississippi River a radio telemetry study was conducted in Pools 4 through 10. Currently lake sturgeon are listed as a species of concern. GIS analysis of available data was performed to determine the spatial relationships that exist between lake sturgeon and their habitat. Aquatic type, wing dam, revetted dam, a...

The effect of altitude on species diversity and its components was recorded in Ganga Chotti and Bedori Hills District Bagh Azad Jammu and Kashmir during 1999-2000. There were 30 plant communities merged in to four plant associations on the basis of cluster analysis. The highest average species diversity was 2.70 at the base (Alt1700 m) in woodland temperate association. Then the diversity decli...
Background and purpose: The use of rangeland medicinal plants and their active ingredients have recently been considered due to their therapeutic and industrial use. The quantity and quality of active ingredients in plants are influenced by environmental factors and ecological stresses of the area. One of the most important factors in extracting the active ingredients of plants is solvent, the ...
The present study was performed to identify diversity indices of herb layer functional groups and its relation to physiographical factors in central Zagros forest, Lorestan. For this purpose, sampling of herbaceous plants was conducted randomly in plots of 2×2 m (n=50) in site. All plants were classified to functional groups including forbs, graminoids and legumes, also Raunkiaerchr('39')s life...
Vertical soundings of the snowpack are essential diagnostic tools for snow hydrologists and avalanche forecasters. Hydrologists require quantitative profiles of snow density from which they can infer the total amount of snow coverage in a region. Because variations in altitude and terrain can result in widely different coverage, they must dig a relatively large number of pits or extract and wei...
Salinity is one of the environmental parameters that its impact on plant species diversity requires further studies. In this research, change of plant diversity was studied along a salinity gradient that was resulted from proximity of water table to the land surface in Incheh Borun plain due to the altitudinal change in northern part of Aq-Qala city. A transect with the length of 1 km was laid ...
