Mediterranean Island Landscapes: Natural and Cultural Approaches (Landscape Series) (Landscape Series)

Mediterranean islands convey many similarities of their biotic ecological, actual and environmental features. There also are many alterations by way of their human colonization and present anthropogenic pressures. This ebook addresses in 3 sections those features and examines the main environmental adjustments that the islands skilled in the course of the Quaternary interval.

Gills 25 In more primitive lamellibranchs neighbouring gill filaments are attached to one another simply through interlocking clumps of cilia (Fig. 10Bi). This rather delicate gill type is termed fillibranch, and is seen in mussels and scallops. In more advanced bivalves neighbouring filaments are joined to each other at regular intervals by tissue connections (interfilament junctions), leaving narrow openings or ostia between them (Fig.

After mussels have released their gametes the mantle is thin and transparent. The mantle is not only the site of gametogenesis but is also the main site for the storage of nutrient reserves, especially glycogen. In M. edulis reserves are laid down in summer and are utilised in autumn and winter in the formation of gametes. For a full discussion of energy metabolism in the mantle and other tissues see de Zwann & Mathieu (1992). The mantle plays a role in the bioaccumulation of metal and organic contaminants in mussels, although the gills, kidney and digestive gland are considered as more important sites.
