Abstract

Background: Because control of runoff generation as well as soil loss is in uenced by freezing-thawing, proper knowledge and insight into the freezing-thawing process in combination with other hydrological processes is essential for executives and planners. However, such dynamic phenomenon and corresponding consequences have not been studied adequately. The present study was therefore planned to comparatively analyze the effects of a freezing-thawing cycle on hydrologic behaviors of loess soil from northeast of Iran. Towards that, the small-size (0.5? 0.50? 0.30 m) erosion plots were subjected to a freezing-thawing cycle in accordance with governing conditions on the region of the origin soil. The plots were subjected to a freezing-thawing

Abstract

The freeze-thaw phenomenon is one of the factors, which has an important role in increasing the qualitative and quantitative loss of soil. However, the dynamics and mechanism of freeze-thaw processes remain unknown. Therefore, adoption of appropriate conservation measures in the highland and mountains region and reduction of the effects of a freeze-thaw cycle on soil loss through application of environmentally friendly and feasible techniques of application of soil microenterprises is critical. Bacteria and cyanobacteria play an important role in the ecosystem function by improving soil physical and chemical properties. Nonetheless, the effectiveness of such microorganism on controlling soil loss has not been studied yet. The present study

Journal PapersCATENA , Volume 187 , 2020 April 1, {Pages 104341 }

Abstract

Newly abandoned rain-fed lands, due to soil quality decline, are the main sources for soil erosion in semi-dry lands agricultural hill-slopes. However, adopting compatible environmentally friend measures have not been adequately implemented. Following various resultful laboratory studies, in this paper, we assessed the effect of field inoculation of cyanobacteria in an abandoned rain-fed land on controlling the natural rainfall-induced soil loss and improving the biological soil crust (BSC) quality mixture of two cyanobacteria (viz. Nostoc sp. and Oscilatoria sp.). The cyanobacteria were inoculated on 22.1?m?× 1.83?m-sized plots located on the study hill-slope. The experiment was carried out for a rainfall period of 6?months under natural

Abstract

Controlling runoff generation and soil loss from hillslopes is a priority for land management. The capability of cyanobacteria as inoculants has recently been utilized in land management, and as a result various lab-scale studies have been conducted. The present study conducted a field-pilot experiment in Miandoab City, south of West Azerbaijan Province, North West Iran, to evaluate the success of cyanobacteria inoculation in runoff and sediment reduction from an abandoned and degraded land at large plot scale under natural rainfall. On 26 December 2017, the cultured native cyanobacteria (Nostoc sp. and Oscillatoria sp.) was inoculated on the 22.1?1.83 m2-plot in three replicates along with three control plots treated by pure water. The run

Abstract

The authors regret to notify about a carelessness mistake committed in the abstract of the paper. Unfortunately, we inserted 135% instead of 13.5% at the end of line 12. It is correct anywhere in the context and I therefore would like to request you to publicize it.

Runoff and soil loss from small plots of erosion-prone marl soil inoculated with bacteria and cyanobacteria under real conditions

Abstract

Land degradation is a major global concern that is exacerbated in the erosion-prone marl and calcium carbonate-rich mudstone slopes. Several studies have therefore focused on finding ways to inhibit soil erosion among which, soil inoculation has been recently introduced as a new technique. However, the success of such treatment has not been adequately taken into account. Following this, in this study, we assessed the hydrological responses of an erosion-prone marl soil due to surface inoculation of bacteria and cyanobacteria. The individual bacteria and cyanobacteria and their combination were inoculated (in three repetitions) on 0.5?m?× 0.5?m-sized plots filled by marl soil from the Marzanabad Region in the north of Iran. The entire plot

Abstract

The present study was conducted to study the morphology of the symbiotic Zooxanthellae with an anemone of Stichodactyla haddoni. Sampling of the sea anemone was carried out in the east coast the Island of Hormuz during a full tide in summer of 2015. The samples were placed in a nitrogen tank and transferred to a laboratory in the shortest possible time. Extracting and counting the Zooxanthellae cells which coexist in symbiosis with the sea anemone were made with an electrical homogenizer. The stages of preparation and fixation of samples were conducted by glutaraldehyde 3%, alcohol and acetone and then the Zooxanthellae cells were examined with the optical microscopes of HP31 and Zeiss and an the electron microscope. The results of the stud

Abstract

Symbiotic dinoflagellates produce bioactive valuable compounds such as carotenoids and lipids used in various industrial fields. However, a small amount of their biomass can be produced with a suspension-based closed photobioreactors. In the present study, we attempted to obtain a high lipid and total carotenoid contents from Symbiodinium sp. by creating optimal light intensity conditions using a Twin-layer photobioreactor. The growth rate, biomass, chlorophyll a concentration, as well as total carotenoid and lipid contents were examined at the light intensities of 50, 100 and 250 μmol m-2 s-1 for 16 days. Based on the results, biomass productivities ranged from 35.7, to 72.0 g m-2 at 50 and 250 ?mol photons m-2 s-1, respectively. The high
