Man's recent colonization of New Zealand has dramatically altered the resident biota and resulted in the introduction of numerous alien organisms to these once remote islands. In reverse, there is increasing evidence of a lesser known export of species to other regions of the world. This volume presents an in-depth review of the level and rate of such invasions, and investigates what controls the success of invaders and the consequences for ecosystems both on land and offshore. It provides invasion biologists everywhere with tests of current theories about those factors leading to the...

Despite the potential benefits that PSSA designation can deliver, recent practice both within the IMO and by individual member States, has considerably undermined confidence in this emerging concept. The focus of this book is on the events within the IMO that have led to this lack of confidence arising. In doing so, this book presents an examination of coastal State practice with the PSSA concept.

In undertaking this analysis, the research provides evidence of the value of the PSSA concept, but also demonstrates its limitations. In this regard, the book presents a reality check...

This volume presents the proceedings of the eighth Colloquium Crustacea Decapoda Mediterranea. It reflects recent advances in decapod crustacean research. The book covers up-to-date issues in decapod crustacean research including genetics, morphology, reproduction, ecology, behavior and fisheries. It is primarily aimed at scientists interested in decapod crustacean research, but other scientists and decision-makers working on marine ecology and fisheries will also find up-to-date information on relevant issues.

It is a well-known fact that eutrophication of coastal waters causes significant changes in the species composition of the primary producers. Usually a shift from an ecosystem dominated by sea grasses or large brown algae to an ecosystem dominated by fast-growing green algae or phytoplankton is observed. While this shift has been documented in a number of research papers and books, the consequences of this shift are less well known. This book focuses on the consequences of such changes for nutrient cycling.

The aim is to investigate how different types of primary producers...

This is the first guide to finding and observing Hawaiian green turtles, or honu. It describes an exciting journey of discovery undertaken by two avid sports divers, Peter Bennett and Ursula Keuper-Bennett, who encountered their first honu twenty years ago while diving off Honokowai, Maui. The Bennetts soon realized that many honu (and green turtles worldwide) were afflicted with debilitating and potentially deadly tumors. They began to document the disease using photographs and videotape and in the process educated themselves about the daily lives of honu. To their surprise, they...

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

Marine natural products have attracted the attention of biologists and chemists the world over for the past five decades. As a result of the potential for new drug discovery, marine natural products have attracted scientists from different disciplines, such as organic chemistry, bioorganic chemistry, pharmacology, biology and ecology. This interest has led to the discovery of over 16,000 marine natural products to date and many of the compounds have shown very promising biological activity. The ocean is considered to be a great source of potential drugs.

The billfish is fixed at the apex of the oceanic food chain. Composed of sailfish, marlin, spearfish, and swordfish, they roam the pelagic waters of the Atlantic and are easily recognized by their long, spear-like beaks. Noted for their speed, size, and acrobatic jumps, billfish have for centuries inspired a broad spectrum of society. Even in antiquity, Aristotle, who assiduously studied the swordfish, named this gladiator of the sea xiphias--the sword.

"The Billfish Story" tells the saga of this unique group of fish and those who have formed bonds with them--relationships forged by...
