Variation in Planning Unit-Size and Patterns of Fish Diversity - Implications for Design of Marine Protected Areas (Paperback):... Variation in Planning Unit-Size and Patterns of Fish Diversity - Implications for Design of Marine Protected Areas (Paperback)
Peter J. Auster, Jason Parent, U. S. Department of Commerce
R458 Discovery Miles 4 580 Ships in 10 - 15 working days

The authors evaluated the effects of planning-unit size on emergent patterns of species-richness hotspots across the Gulf of Maine-Georges Bank Large Marine Ecosystem. The authors used data on the distribution of fishes as information for this taxon is the most geographically and temporally comprehensive due to their economic value and requirements for active and ongoing management. They also investigated both how spatial scale affects geographic patterns of species richness as well as the effect of sample size per planning unit on such patterns. An effort-standardization approach based on a bootstrap procedure was used to address variation in sample effort across the geographic region. In order to understand the equivalence of hotspots in terms of conservation value, the authors also investigated patterns of species similarity among hotspots across the gradient of planning-unit size.

In "Shell Games," journalist Craig Welch delves into our nation's waters and wildlands in search of America's most unusual criminals. The resulting detective story is filled with butterfly thieves, bear poachers, shark-trafficking pastors--and a rogues' gallery of double-crossing crooks who get rich smuggling bizarre marine creatures.

Outlaw scuba divers pursue this prize while dodging cops, committing arson, and hiring hit men to eliminate their rivals. Detective Ed Volz has spent decades chasing fish and wildlife smugglers. Now, he and a team of federal agents are desperate to take down the most remarkable thief they've ever hunted: a darkly charming con man who works both sides of the law and calls himself the "Geoduck Gotti."

Anyone who spends time beside the sea knows there’s a wealth of ‘treasure’ to be found, be it natural or manufactured, living or washed up. Beachcombing in South Africa is a friendly guide to the seashore’s rich pickings.

Short chapters such as Floaters and drifters, Sea-beans, Sponges, Eggs and egg cases, and many more, detail what can be found and how to interpret or identify specimens. Items may reveal links to activities or biological events in the nearby ocean – or, perhaps, thousands of miles away. They may relate to human activities, such as fish or bird tagging, or be oceanographic instruments separated from their moorings. Or they may be part of the growing menace of otsam and jetsam from the planet’s burgeoning human population.

This book will enhance the experience of beachcombing, satisfy curiosity about finds, and contribute to a better understanding of the life in our oceans and along our shores.

Aimed at a wide audience of beach strollers, dog walkers, anglers, bird watchers and families who share a fascination with the seashore and its treasures.

In this passionate, spiritual narrative of her adventures in the big blue, Julia Whitty emerges as one of our finest writers on the mystery, beauty, and fragility of the undersea world.
