Assessing the ecological status of plankton in Anjos Bay

Assessing the Classification Indices of Ecological Quality Status Using Benthic Macrofauna Identification in Gorgan Bay

The present study was conducted for the first time to investigate and identify the ecological quality status (EcoQ) of Gorgan Bay and also to emphasize the degree of agreement between the results of different benthic macrofauna indices, introduction of appropriate index and utilization of basic results in environmental management programs in the region. To do, 22 sites were selected and macrobe...

Ecological risk assessment using heavy metals from surface sediments of Nayband Bay and Asaluyeh region (Northern Persian Gulf)

The toxicity of heavy metals in sediments of the Nayband Bay and Asaluyeh region and potential ecological risk to sediment organisms assessed. Three stations with different degrees of vulnerability of South Pars Oil and Gas Activities (1: Control - 2: medium affected and 3: severely affected) were selected in the study area. Sediment sampling at each station in both cold and hot seasons (2010) ...

Ecological Problems of Gorgan Bay in the Southeast Corner of the Caspian Sea (Iran) and Ways of Improvement

Ecological Assessment of Organic Pollution in the Gorgan Bay, Using Palmer Algal Index

The problem of pollution in the Caspian sea has attracted increasing scientific concerns in recent years, but still, there is limited data relevant to the Gorgan bay. The current study aimed to evaluate the organic pollution of the Gorgan Bay, using Palmer Algal Index. Sampling was conducted seasonally in triplicate from summer 2017 to spring 2018. Phytoplankton samples were collected from surf...

Assessing benthic health of hard substratum macrobenthic community using soft bottom indicators and their relationship with environmental condition

This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relation with environmental factors. For this purpose benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate and pho...
