| Summary: | The study of ecological indicators, defining and establishing the means of measuring the health of the environment, is of great importance. The most important elements of ecosystems are the biological components, and environmental impact assessment of ecosystems will therefore require that these components are seriously laid out. It is, for example, not sufficient to assess the water quality by the use of physicochemical parameters, although their determination can be carried out much more rapidly. There exists, in general, a relation between species composition and water quality. It is well known that mussels are extensively utilized as a biological indicator of pollution of both marine and freshwater ecosystems. The reason is that the mussel is a sessile, filter-feeding, and able to accumulate within its tissues many of the contaminants. In addition, mussels show a wide geographical distribution as they permit the survey of extensive coastal and inland areas. The contaminants accumulated in the tissues of mussels may cause a “stress syndrome” with alteration to their physiology. On the other hand, global warming does affect the pH level, especially the marine water resulting increase in acidity. This can be the outcome of the existing genetic variation in natural populations of mussels. They because allow themselves to adapt to declining pH levels in the aquatic ecosystem caused by carbon emissions. We, therefore, focus on the factors that possibly effect the mussel biodiversity in aquatic ecosystems in relation to climate change as well as pollution concerned. |
