Nine Dictyuchus isolates were obtained from floating and decaying twigs and leaves in Anzali lagoon, Anzali County, Guilan province, Iran. They are interestingly distinguished from current Dictyuchus species by the presence of dictyoid and achlyoid type of zoospore discharge, abundant fusiform and spherical gemma, and the absence of any sexual apparatus. In addition, phylogene...

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 copp...

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 significan...

The current study was performed to determine Hirudinea species diversity collected from rice fields of Guilan province June 2012 2020. This reports the most recent information on leech (Annelida, Clitellata) in this region. Morphological characters and DNA barcode analysis were used identify samples. According acquired results, there two families zone (Glossiphoniidae Hirundinidae). Based morph...

Hydrogen is a clean and environmentally friendly energy vector that can play an important role in meeting the world’s future needs. Therefore, comprehensive study of potential for hydrogen production from solar could greatly facilitate transition to economy. Because by knowing exact amount production, cost-effectiveness its be compared with other methods production. Considering above, it seen s...
