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 and fauna continues to be poorly described in current textbooks. This concise, readable introduction to benthic ecology builds upon the strengths of the previous edition but has been thoroughly revised throughout to incorporate the new technologies and methods that have allowed a rapid and ongoing UR - https://search.ebscohost.com/login.aspx?direct=true&scope=site&db=nlebk&AN=265007 ER -
