This chapter demonstrates that the ecosystems supporting the marine fisheries on Canada's east and west coasts have greatly changed under exploitation by industrial fisheries. These changes, reflected in the decline in the abundance of key species and the composition of the fisheries' landings, imply changes in the support provided by the ecosystems in which the fisheries are embedded. This fur...

The Mytilos project was carried during the last 3 years (2004-2006) in order to evaluate the level of chemical contamination along the coasts of the western basin of the Mediterranean Sea. Active mussel watch consisted of caged (12 weeks) Mytilus galloprovincialis at 123 stations along the Mediterranean coasts of Spain, France, Italy, North Tunisia, Algeria and Morocco. Results indicated total ...

Ianiropsis (G.O. Sars, 1897-99) is a complex and poorly understood genus composed of species similar to one another (BRUSCA & IVERSON, 1985), as well as similar to Janira (Leach, 1814). Species within this genus are mainly indigenous in the Pacific Ocean, apart from Ianiropsis breviremis (G.O. Sars, 1883), which occurs in the North-East Atlantic, and Ianiropsis palpalis (Barnard, 1914) on the S...

This study describes the geochemical distribution of lead (Pb) and identifies the critical factors that significantly control Pb distribution and speciation in coastal and estuarine sediments around India by using published data from the literature. Crustal sources influence the abundance of Pb in coastal sediment from the south-east and central-west coast of India. Parts of north-east, north-w...
