Book Description
Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited.

Book Description
Behavior and Ecology discusses the ecology and behavior of crustaceans. It presents an update and overview of most of the dominant lines of research in crustacean biology. This book is divided into six chapters. Chapter 1 deals with the rapidly advancing topic of how crustaceans communicate with members of the same species as well as on an interspecific basis. Chapter 2 provides a synthesis and review of patterns of movement and orientation of crustaceans in nature. Chapter 3 reviews the basic concepts in the regulation of biological rhythms, surveys rhythms in Crustacea, and then analyzes the data from an ecological perspective. Chapter 4 summarizes symbiotic relationships of crustaceans with other crustacean and noncrustacean hosts. Chapter 5 cites work on adaptation of egg and development to the environment. Chapter 6 discusses assemblages of organisms into populations and communities. This book is a valuable source for zoologists, paleontologists, ecologists, physiologists, endocrinologists, morphologists, pathologists, and fisheries biologists, and an essential reference work for institutional libraries.

Book Description
The driving forces of natural selection leave their traces in the shapes of living creatures and their patterns of distribution. In this thoughtful and wide-ranging discussion of evolutionary process and adaptive response, Geerat Vermeij elucidates the general principles that underlie the great diversity of marine forms found in the world's great oceans.

Book Description
A comprehensive introduction to the natural history and intertidal ecology of East Coast shorelines Atlantic Shorelines is an introduction to the natural history and ecology of shoreline communities on the East Coast of North America. Writing for a broad audience, Mark Bertness examines how distinctive communities of plants and animals are generated on rocky shores and in salt marshes, mangroves, and soft sediment beaches on Atlantic shorelines. The book provides a comprehensive background for understanding the basic principles of intertidal ecology and the unique conditions faced by intertidal organisms. It describes the history of the Atlantic Coast, tides, and near-shore oceanographic processes that influence shoreline organisms; explains primary production in shoreline systems, intertidal food webs, and the way intertidal organisms survive; sets out the unusual reproductive challenges of living in an intertidal habitat, and the role of recruitment in shaping intertidal communities; and outlines how biological processes like competition, predation, facilitation, and ecosystem engineering generate the spatial structure of intertidal communities. The last part of the book focuses on the ecology of the three main shoreline habitats—rocky shores, soft sediment beaches, and shorelines vegetated with salt marsh plants and mangroves—and discusses in detail conservation issues associated with each of them.

Book Description
The impetus for this volume comes from two sources. The first is scientific: by virtue of a preference for certain large benthic invertebrates as food, sea otters have interesting and significant effects on the structure and dynamics of nearshore communities in the North Pacific. The second is political: be cause of the precarious status of the sea otter population in coastal California, the U.S. Fish and Wildlife Service (USFWS) announced, in June 1984, a proposal to establish a new population of sea otters at San Nicolas Island, off southern California. The proposal is based on the premise that risks of catastrophic losses of sea otters, due to large oil spills, are greatly reduced by distributing the population among two geographically separate locations. The federal laws of the U.S. require that USFWS publish an Environmental Impact Statement (ElS) regarding the proposed translocation of sea otters to San Nicolas Island. The EIS is intended to be an assessment of likely bio logical, social, and economic effects of the proposal. In final form, the EIS has an important role in the decision of federal management authority (in this case, the Secretary of the Interior of the U.S.) to accept or reject the proposal.
