Freshwater Mussels

Abbie Gascho Landis first fell for freshwater mussels while submerged in an Alabama creek, her pregnant belly squeezed into a wetsuit. After an hour of fruitless scanning, a mussel materialized from the rocks—a little spectaclecase, herself pregnant, filtering the river water through a delicate body while her gills bulged with offspring. In that moment of connection, Landis became a mussel groupie, obsessed with learning more about the creatures' hidden lives. She isn't the only fanatic; the shy mollusks, so vital to the health of rivers around the world, have a way of inspiring unusual devotion.

The monograph focuses on the European freshwater pearl mussel Margaritifera margaritifera, which is an endangered bivalve species. Most of its populations in the Russian section of the Baltic Sea basin had never been studied, although they were known in the past to the pearl fishers. “Rediscovery” included search for the previously unknown populations, revealing the facts of population extinctions, analysis of negative impacts, elaboration of conservation measures, and revealing of regularities in distribution. Patterns of land use and river management were analyzed.

The book represents the current trend of research in basic and applied malacology. This book represents a rich source of malacological information for the scientists, teachers and students.
