Anzali Wetland as a listed habitat in Montreux Record, was investigated for the mammal fauna during Jan. 2015 - Jan. 2016. About 165 km of water bodies and 200 km around Anzali Wetland were patrolled, respectively. By applying different methods, such as direct observation, different signs recording, using different sampling traps, nets and camera traps, twenty mammal species were identified fro...
In this study, tissue changes of the sex organs in the Tinca tinca fish in Anzali wetland and breeding conditions was compared. 96 fish were collected from the cultivating pool and 36 others from Anzali wetland. In the microscopic study of Tench and ovaries and testicles in different stages of sexual activity, from the samples of the wetland, from 3 fish of ovary, two of them were in stage III-...
plant-based remediation (i.e. phytoremediation) is one of the most significant eco-sustainable techniques to cope with devastating consequences of pollutants. in the present study, the potential of a wetland macrophyt (i.e. potamogeton crispus ) for the phytoremediation of heavy metals (i.e. cu, cr, pb, as and cd) in the anzali wetland was evaluated. the results showed that p. crispus tends to ...
Heavy metal concentrations and magnetic susceptibility of sediment samples were analyzed as indicators of urban and industrial contamination in Anzali wetland in Gilan, Iran. The aim was to investigate the suitability of magnetic properties measurements for indicating heavy metal pollution. The concentration of six heavy metals (Ni, Cr, Cd, Zn, Fe, and Pb) was determined in different depths of ...
Heavy metals such as copper and zinc are essential for fish and human metabolism. But excessive concentrations of heavy metals impair ecosystems as some of those cause potential bioaccumulation in live beings. Fish are the major inhabitants in water bodies and can be highly affected by these toxic pollutants. The presence of these contminations in fish is known to cause various diseases in huma...
the length- length (llrs), length-weight (lwr) relationships and relative condition factor (kn) of 505 specimens of pike, (esox lucius linnaeus, 1798) from anzali wetland, southwest of the caspian sea, were studied from april 2012 through march 2013. the length-length relationships among total length (tl), fork length (fl) and standard length (sl) for pike were found to be highly significant (r...
background: anzali wetland has been subjected to high levels of pollution due to contamination from several industrial sites in addition to agricultural chemicals. mussels have been widely used for monitoring pollution in aquatic ecosystems, because they, as filter feeders, bioaccumulate pollutants. therefore we decided to evaluate anodonta cygnea for its application as a bio-monitor for copper...
