Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...

Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...

In this study, species composition, density and biomass of zooplanktons including Rotatoria, Protozoa and Meroplanktons were sampled using Juday net with mesh size of 100 µ at depths of 5, 10 and 20 meters in southern Caspian Sea (Babolsar) in two seasons of cold (Feb. 2015) and warm (June 2015) . This study identified Asplanchna sp. and Synchaeta sp. from Rotatoria, and Balanus sp., Pelecypoda...

Twenty-two isolates of Sclerotium rolfsii causing spotted leaf rot from Varanasi, India were grown on 6% Cyperus rotundus rhizome meal agar (CRMA) medium for the induction of athelial stage (Athelia rolfsii). Only one isolate obtained from Sphaeranthus indicus formed basidial stage on CRMA medium while the other 21 isolates did not. Basidial stage was also produced in S. indicus isolate at diff...

Estimation of forest biomass has received much attention in recent decades. Airborne and spaceborne (SAR) have a great potential to quantify biomass and structural diversity because of its penetration capability. Polarizations are important elements in SAR systems due to sensitivity of them to backscattering mechanisms and can be useful to estimate biomass. Full Polarimetric Synthetic Aperture ...

Microbial fuel cell (MFC) mathematical model was established with suspended microorganisms, biomass on the electrode material, soluble chemical substrates and intermediary. By simulating the process of the substrate degradation, biomass growth and the electric current production process, With different initial biomass concentration, suspended microbial biomass and biomass attaching on electrode...

Biomass is a key factor in dynamics evaluation of ecosystems, biodiversity level and their stability. Biomass measurement is performed every year to evaluate range ecosystems (investigating the trend of changes), range management (suitable browsing systems) and cover assessment in rangelands. As direct biomass measurement is time-consuming, has costs and destroy rangelands non-destructive metho...
