This extension note describes the basic ecological features of wetland ecosystems. It is a foundational document that provides important concepts and background information to be applied in future extension notes on wetland management. Major topics and concepts covered in this document are: • definition of a wetland ecosystem and comparison of characteristics with other related ecosystems, • re...

Anzali International wetland is one of the most valuable water resources as registered in Ramsar convention with an extent of about 150 km2 in the south Caspian Sea. This wetland, not only has ecological and biological importance for migratory birds and rare fish species, but also is used for farms to discharge into the Caspian Sea through this wetland. Therefore its pollution control is very ...

This resaerch was conducted in order to study the importance of economic, social and touristic to the Anzali wetland, north of Iran. Data was collected through "field research" and "documentary research". Nominal scales, Likert and Guttman scales were used for the compilation of questionnaires. Findings of the present research indicate that the variation of population growth rate in the periph...

Methane oxidation in the rhizosphere of wetland plants may significantly attenuate methane losses from wetland soils to the atmosphere. Our objective was to measure the extent of methane production and oxidation in the rhizosphere of a common wetland plant (Sagittaria landfolia L. Per.). Methyl fluoride (CH3F), a water-soluble gas and a specific inhibitor of methane oxidation, was used in conju...

conservation and sustainability of natural ecosystems and sustainability of rural communities by good linking between communities and ecosystems through developing of alternative lifestyles are essential. inthisregard based on the ecovillage model as a model of sustainable lifestyle was paid to provide appropriate strategies for sustainable living in rural societies around wetland with identify...

Background: Sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. This study was carried out for assessing Co, Ni, and Zn in sediment samples of Mighan Wetland using geo-accumulation index in 2013. Methods:The sediment samples were taken from 11 stations. The samples were subjected to bulk dige...

 Bamdzh wetland of Khuzestan Province is at downstream of Shavvr River. Its area is approximately 4 hectares. Due to the loss of wetland area, especially in recent decades, this study investigated the effects of a five-year drought (2007-2012) in the Shavvr region and the pond ultimately.
