Zaribar Lake is a little shallow lake in Kurdistan province of Iran and it is faced to eutrophication.The study of phytoplankton biomass-nutrient relations is important in eutrophication management and there are many empirical models to predict phytoplankton biomass (chlorophyll a) based on nutrient (nitrogen and phosphorous) amounts in the lake. Evaluation of these empirical models and compar...

The aim of this study is to assess the eutrophication and trophic status based on different indices and also reference threshold values in the Iranian coastal waters of the southern Caspian Sea (ICWSCS). The water samples (three replicates) were collected along four transects (off the coast from Anzali, Tonekabon, Nowshahr and Amirabad) between spring 2013 and winter 2014. The results show mark...

The aim of this research was to investigate the environmental impacts of olive fruit production under different orchard size and upon organic and common agro-systems through Life Cycle Assessment (LCA) methodology in Rudbar region, Guilan province, northern Iran. The data were collected using a self-structured questionnaire and face-to-face interview with 305 olive growers in the study region. ...

eutrophication is known as the most common problem in water bodies, caused by high concentrations of different nutrients leading to unbalanced growth of aquatic plants, among other symptoms. hence, the possibility of eutrophication prediction can be beneficial to the sustainable management of these natural resources and create an opportunity to control their trophic conditions over time. a soft...
