Book Description
Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Book Description
This is the first report of the Circumpolar Biodiversity Monitoring Program (CBMP) to summarize status and trends in biotic elements in the arctic marine environment. The effort has identified knowledge gaps in circumpolar biodiversity monitoring. CBMP is the cornerstone program of Conservation of Arctic Flora and Fauna (CAFF).

Book Description
The book describes the main marine and coastal biological systems of Passamaquoddy Bay and adjacent waters and the oceanographic and meteorological characteristics of the area. Subject areas begin with meteorolgy and oceanography. The second group covers the intertidal systems with chapters on rocky intertidal shores, rock pools, coarse sedimentary shores and salt marshes. The third general section covers hard and sedimentary sublittoral habitats. Following chapters discuss pelagic systems under the headings fishes, phytoplankton, larger zooplankton, and microzooplankton. Three chapters deal with the birds, amphibians and reptiles, and marine mammals. Finally coastal vegetation is described.

Book Description
This book offers the first comprehensive review of parasitic Crustacea, which are among the most successful and diverse parasites. Starting with an introductory chapter, followed by an historic overview and topic-specific chapters, each presenting a different aspect of parasitic crustacean biology, it enables readers to gain a better understanding of how these parasites function and allows direct comparisons between the different parasitic crustacean groups. The authors also discuss, in depth, the adaptations and interactions that have made parasitic Crustacea as successful as they are today, covering topics ranging from the history of their discovery, their biodiversity, phylogeny, evolution and life strategies to their role as vectors, or hosts of other organisms, and their significance in ecological processes. Consisting of ten chapters from leading international experts in the field, this volume offers a one-stop resource for all researchers, lecturers, students and practitioners.
