Wetlands as water resources have a special place in the semi-arid plateau of Iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. Determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. Ecological...
The Iberian Peninsula possesses a particular richness of inland saline lakes which mainly occur in three endorheic regions in Aragón, La Mancha and Andalucía. The distribution of benthic microbial mat communities in these lakes is described and related to the ionic composition, salinity fluctuations, inundation period and sediment features. It was found that the cyanobacterium Microco1eu.s chth...

external costs of environmental degradation are often ignored in economic analysis of projects. the mail goal of the paper is to economically analyze the current alternatives of meighan wetland utilization including extraction of sodium sulfate, aquaculture of artemia and integrative alternative considering external costs of wetland degradation. in order to detect eventual degradation of wetlan...
Recognizing of plants present in a region is considered as a baseline study for ecological research, management and conservation of plants. The purpose of this study was to collect and identify the plants of Azizak and Paein Ahmad kola Wetlands of Babolsar in Mazandaran province. After specifying the boundaries of the study areas on the map and conducting field visits, the plants were collecte...
Anostracan zoogeography, biogeography, and habitat preferences have predominately been studied as related to the water quality parameters of their seasonally astatic wetland habitats. However, since water quality in seasonally astatic wetlands can fluctuate dramatically over a range of time scales, water quality data are generally of limited usefulness. Anostracan taxa occurrences in each of th...
Inland wetlands are of the most important natural terrestrial types of water resources. Against its importance in protecting and improving biodiversity, air quality and macro-climatic condition of their regions, industrial development, and urbanization treat their natural existence and behavior. Therefore, monitoring and quality evaluation of wetlands are necessary to analyze and infer their na...
The role of plants in the treatment of effluents by constructed wetland (CW) systems is under debate. Here, we review ways in which plants can affect CW processes and suggest two novel functions for plants in CWs. The first is salt phytoremediation by halophytes. We have strong evidence that halophytic plants can reduce wastewater salinity by accumulating salts in their tissues. Our studies hav...
anzali wetland on the south west of caspian sea is a unique ecosystem was registered as ramsar site at 1975. anzali wetland was deteriorated due to numerous disorder and poor water quality. the riverin input were strongly affective in the process of eutrophication where the eastern and central region was more degraded. the first survey on the eutrophication process was conducted at 1969, since ...
