In this study, the degradation potential of five polycyclic aromatic hydrocarbons (PAHs) by aerobic mixed bacterial cultures was investigated. Microorganisms were isolated from hydrocarbon contaminated soils of Shadegan wetland located in southwest of Iran. The degradation experiments were conducted in liquid cultures. PAH or PAHs concentration was 100 mg/L at the beginning of degradation e...

Wetlands are one of the most important ecosystems due to their critical services both humans and environment. Therefore, wetland mapping monitoring essential for conservation. In this regard, remote sensing offers efficient solutions availability cost-efficient archived images over different spatial scales. However, a lack sufficient consistent training samples at times is significant limitatio...

Wetlands are valuable natural capital and sensitive ecosystems facing significant risks from anthropogenic climatic stressors. An assessment of the environmental risk levels for wetlands’ dynamic can provide a better understanding their current ecosystem health functions. Different defined by considering categories probability severity each in environment. Determining provides general overview ...

In this study frequency and composition of plankton in Shadegan wetland was carried out in 5 stations during 2007-2008. Genus qualitative identification and their composition and quantitative frequency aspect were studied (for phytoplankton chlorophyll a). Frequency of total 42 genus phytoplankton in 4 classes Bacilariophyceae (Diatom), Cyanophyceae, Chlorophyceae and Dinophyceae are 69.4, 22.2...
