Ecology of marine sediments : from science to management /
Marine sediments are the second largest habitat on earth and yet are poorly understood. This book gives a broad coverage of the central topics in the ecology of soft sediments. - ;Marine sediments provide the largest habitat on planet earth, yet knowledge of the structure and function of their flora...
