RESEARCH ARTICLE This paper provides an overview of some of the research activities carried out in the Oristano 1 Lagoon-Gulf system (western Sardinia, Italy) aimed at assessing the ecological quality of a complex transitional-coastal system renowned for its naturalistic and economical value, but subject to an increasing anthropogenic pressure. Numerical models concerning physical and ecologica...

It is well known that chlor-alkali industries using mercury as a cathode are an important source of this heavy metal to aquatic environments. Once discharged into rivers, lakes or coastal waters, mercury accumulates in sediments and in the aquatic food web (Gonzalez, 1991). Both elemental mercury and its compounds are noxious to all living organisms, and are bioaccumulative and persistent. Meta...

This section aims to identify feasible policy options that target key components identified in the Causal chain analysis in order to minimise future impacts on the transboundary aquatic environment. Recommended policy options were identified through a pragmatic process that evaluated a wide range of potential policy options proposed by regional experts and key political actors according to a nu...

The population dynamics of the capitellid polychaete Capitella aff. teleta were studied in Gamo Lagoon, located northeast Japan, for subsequent 2 years from 2016, when a series restoration works was conducted following 2011 Great East Japan Earthquake and tsunami. found to be widely distributed estuary side, where levee located, innermost part but more abundant part, which is rich organic matte...

Sedimentation causes land accretion, silting river water, lagoon, and mangrove degradation. The current study aims to analyze the potential impact of sedimentation toward lagoon ecosystem in Segara Anakan Lagoon. research methods used mapping analysis, total suspended solid analysis (TSS), rate biodiversity covering. result showed that (1) value TSS between 0.25-1,16 g L-1 (2) sediment flux 6,8...

the chromosomal spread and karyotype of bleak (alburnus alburnus) from anzali lagoon were identified using tissue squashing techniques with injection of 0.5ml/100g body weight of 0.01% colchicines solution in fish fingerlings. kidney and gill tissues were then extracted and chopped in kcl 0.045m for 20 min and fixed in carnoy solution in 3 stages. the chromosomal spreads were stained in 20% gim...

metal contents viz., cu, ni, co, zn and cd in sediment cores recovered from the vembanad lake, the largest estuarine-lagoonal system on the west coast of india, were analysed to understand the pollution levels and the impact on the coastal environment. of the three cores studied, vc-10 shown enrichment in all metals compared to other cores, as it is located in the vicinity of industrial area. f...

 In recent years, rangelands have been regarded as potential carbon sinks. One of the most widely suggested options to sequester more C in rangelands is the restoration of the degraded rangelands through grazing the exclusion. In present study, the effects of exclusion on the carbon sequestration of Gomishan rangelands were investigated. Three transects were established in a key area inside and...
