The Oceanic Hydrozoa is a seminal piece of marked distinction by Huxley, the eminent biologist, nicknamed Darwin's bulldog for his advocacy of Charles Darwin's theory of evolution. This monograph, first published by the Ray Society in 1859, is a description of the Calycophoridae and Physophoridae observed whilst Huxley served as Assistant-Surgeon on the survey vessel HMS Rattlesnake in the years 1846-50. The twelve plates at the back of the book have become an invaluable record of the study of the Oceanic Hydrozoa.

Through quiet meadows, rolling hills, leafy suburbia, industrial sites, and a changing London riverside, Mick Sinclair tracks the Thames from source to sea, documenting internationally-known landmarks such as Tower Bridge and Windsor Castle and revealing lesser known features such as Godstow Abbey, Canvey Island, the Sanford Lasher, and George Orwell's tranquil grave.

Rivers under Siege is a wrenching firsthand account of how human interventions, often well intentioned, have wreaked havoc on West Tennessee's fragile wetlands. For more than a century, farmers and developers tried to tame the rivers as they became clogged with sand and debris, thereby increasing flooding. Building levees and changing the course of the rivers from meandering streams to straight-line channels, developers only made matters worse. Yet the response to failure was always to try to subdue nature, to dig even bigger channels and construct even more levees-an effort that reached its sorry culmination in the U.S. Army Corps of Engineers' massive West Tennessee Tributaries Project during the 1960s. As a result, the rivers' natural hydrology descended into chaos, devastating the plant and animal ecology of the region's wetlands. Crops and trees died from summer flooding, as much of the land turned into useless, stagnant swamps. The author was one of a small group of state waterfowl managers who saw it all happen, most sadly within the Obion-Forked Deer river system and at Reelfoot Lake. After much trial and error, Johnson and his colleagues in the Tennessee Wildlife Resources Agency began by the 1980s to abandon their old methods, resorting to management procedures more in line with the natural contours of the floodplains and the natural behavior of rivers. Preaching their new stewardship philosophy to anyone who might listen-their supervisors, duck hunters, conservationists, politicians, federal agencies-they were often ignored. The campaign dragged on for twenty years before an innovative and rational plan came from the Governor's Office and gained wide support. But then, too, that plan fell prey to politics, legal wrangling, self-interest, hardheadedness, and tradition. Yet, despite such heartbreaking setbacks, the author points to hopeful signs that West Tennessee's historic wetlands might yet be recovered for the benefit of all who use them and recognize their vital importance. Jim W. Johnson, now retired, was for many years a lands management biologist with the Tennessee Wildlife Resources Agency. He was responsible for the overall supervision and coordination of thirteen wildlife management areas and refuges, primarily for waterfowl, in northwest Tennessee.

This document presents the results of the monitoring of a repaired coral reef injured by the M/V Jacquelyn L vessel grounding incident of July 7, 1991. This grounding occurred in Florida state waters within the boundaries of the Florida Keys National Marine Sanctuary (FKNMS). The National Oceanic and Atmospheric Administration (NOAA) and the Board of Trustees of the Internal Improvement Trust Fund of the State of Florida, ("State of Florida" or "state") are the co-trustees for the natural resources within the FKNMS and, thus, are responsible for mediating the restoration of the damaged marine resources and monitoring the outcome of the restoration actions. The monitoring program at the Jacquelyn L site was to have included an assessment of the structural stability of installed restoration modules and biological condition of reattached corals performed on the following schedule: immediately (i.e., baseline), 1, 3, and 6 years after restoration and following a catastrophic event. Restoration of this site was completed on July 20, 2000. Due to unavoidable delays in the settlement of the case, the "baseline" monitoring event for this site occurred in July 2004. The catastrophic monitoring event occurred on August 31, 2004, some 2 1/2 weeks after the passage of Hurricane Charley which passed nearby, almost directly over the Dry Tortugas. In September 2005, the year one monitoring event occurred shortly after the passage of Hurricane Katrina, some 70 km to the NW. This report presents the results of all three monitoring event

The size and form of lakes regulate many general transport processes, such as sedimentation, resuspension, diffusion, mixing, burial and outflow. Lakes: Form and Function discusses how much of the variations among lakes in fundamental ecosystem characteristics may be related to lake morphometry, catchment area features, climatological factors and measurement uncertainties. The transport processes regulate many important variables, such as concentrations of phosphorus, suspended particulate matter, pH and color. These variables, in turn, affect primary production, which regulates secondary production, for example of zooplankton and fish. This book discusses such relationships using both empirical data and statistical analyses, and mechanistic principles and models. Researchers and students in limnology, as well as consultants and administrators interested in management and studies of lake systems, will enjoy reading this book. Lars Hakanson received his PhD in Physical Geography from Uppsala University, Sweden. He has written several papers and books related to recent sedimentological processes in lakes, rivers and coastal areas, to mass-balance modelling of radionuclides, nutrients and metals, to aquatic foodweb models and to water pollution.

Twelve months of visits to a mountain lake tells more than twelve tales. The solitude found during a Wednesday in the winter is completely different from the chaos found on a Saturday in the summer. The seasons make one set of changes. We make the other. The combination produces a much more interesting set of experiences that can't be revealed in one visit or in a page of some guidebook.

Merritt Lake hides on the east side of the Cascade Mountains, between the crest of the range that partly protects it from Pacific storms, and halfway to the deserts and cities of Central Washington. The lake is protected by Nature more than legislation, within a land that is punctuated by avalanches and forest fires. Luckily, it is even better at producing quiet, serene moments.

Nature's residents range from rodents to raptors, and from delicate flowers to massive pine forests. Most of us drop by for peacefulness, exercise, fishing, or adventure, but some build campfires while forests burn, or fire guns during busy weekends.

Get to know the fuller, richer story that so few of us take the opportunity to experience.

This Programmatic Environmental Impact Statement (PEIS) systematically evaluates the short and long-term environmental and socioeconomic effects related to the implementation of seagrass restoration and seagrass injury prevention projects in the Florida Keys National Marine Sanctuary (FKNMS). The goal of this PEIS is to describe a range of seagrass restoration techniques, used for both primary and compensatory restoration projects and seagrass injury prevention actions that potentially may be implemented in the FKNMS. The types of seagrass restoration and injury prevention projects proposed in this plan will be implemented with funds collected through natural resource damage assessment (NRDA) settlements for injuries to seagrasses within the FKNMS. The anticipated beneficial and adverse environmental and socioeconomic impacts of each restoration technique are discussed in detail.

This is a reprint of the classic first published in 1957. One of the authors, Raymond Beverton, recently died. His co-author, Sidney Holt, has written a new Foreword to this printing in which he reviews events in fisheries research and management through the past 50 years as these relate to their joint work. On the Dynamics of Exploited Fish Populations has become the most widely cited fisheries book ever published and the fact that the bulk of the information contained within its covers is still valid has led to this reprinting. Beverton and Holt's great work created a solid foundation for one of the two major global visions of the science of fisheries. This book was the genesis of the modern age-structured approach to the optimal management of fishery resources. Their approach led directly to a formulation of the fishery catch equation with almost universal applicability. Its advantage was that it produced easily interpreted outputs that could be clearly and directly applied to any fishery. Ultimately, this approach was the forerunner to VPA and allied techniques, the core of modern catch forecasting used in setting quotas and in managing commercial fisheries worldwide. Although the perception of the objectives of fisheries research has changed since the 1950s, and computers now enable calculations, data analysis, and theoretical exploration far beyond their capability at the time, Beverton and Holt will continue to be a source of inspiration and insight for many years to come. Sidney J. Holt was educated at Reading University, England. He has held academic positions at St John's College, Cambridge, England; University of California at Santa Cruz; University of Rhode Island; University of Malta. He is the author of 400 scientific papers, book chapters and popular articles, especially in the fields of fisheries science and management, conservation, protection of marine mammals, especially whales. He served 25 years in the United Nations system of Specialised Agencies (including the FAO in Rome, UNESCO as Secretary of the Intergovernmental Oceanographic Commission and Director of Division of Marine Science; Marine Mammals; Advisor to the United Nations Environment Programme; UN Adviser on Mediterranean Marine Affairs, in which capacity he founded and served as first Director of, the International Ocean Institute, in Malta). Since his formal retirement Dr Holt has served on the delegations of Italy and of the Republic of Seychelles to the International Whaling Commission, and also as adviser to the delegations of France and Chile. Dr Holt has worked extensively with several Non-Governmental Organisations concerned with marine conservation. Apart from continuing to write and campaign Dr Holt advises the Third Millennium Foundation, and serves as Executive Director of the International League for the Protection of Cetaceans, which he founded 18 years ago.

The seasons make one set of changes. We make the other. The combination produces a much more interesting set of experiences that can't be revealed in one visit or in a page of some guidebook.Barclay Lake sits about an hour northeast of Seattle on the soggy side of the Cascade Mountains. It is an easy hike within challenging terrain and is one of those rare places where the extremes of hiking can be found. Families can camp with kids and climbers can assault rocky spires.Different experiences give people different points of view. It is no wonder that debates about the environment and land-use are so complex and confusing. Barclay Lake is one place where those various points of view meet and conflict.

One population of a truly fascinating species; The Dolphins of Hilton Head introduces readers to the unique population of bottlenose dolphins that inhabit the warm water and brackish salt marshes of South Carolina's inland coastal waterways. Drawing on years of research in Hilton Head and the latest discoveries of scientists throughout the world, Cara Gubbins describes this atypical habitat and explains how the distinctive behaviors of Hilton Head dolphins distinguish them from other populations. She identifies their particular behavior patterns, vocalizations, behavioral ecology, and local traditions. Gubbins also offers practical suggestions on how best to view and understand these animals while visiting the island. Framing her study with a general overview of dolphins and their habits, Gubbins explores the natural history, ecology, and evolution of free-ranging Atlantic bottlenose dolphins in South Carolina. She compares this population with others throughout the world to reveal the South Carolina dolphins' innovative foraging techniques, novel social system, and unconventional habitat use patterns. Gubbins debunks widely held myths about the animals, addresses conservation issues that will affect their future in South Carolina waters, and discusses environmental problems that threaten them worldwide. While Gubbins looks specifically at the dolphins of Hilton Head, her guide helps readers understand these animals throughout the world. She offers advice not only for spotting dolphins but also for interpreting such specific behaviors as feeding, socializing, resting, traveling, and communication.

Shark picks up where previous Adrenaline titles such as Rough Water and Deep Blue left off, with a collection focusing on man's terrifying interactions with one of the planet's most frightening beasts--an animal that arouses our most primal fears--fears that were recently brought to the surface by an outbreak of fatal attacks on this country's beaches. From novelists to sailors to oceanographers to divers, man's encounters with sharks have produced a diverse body of gripping, often inspired writing by great names in adventure literature. Along with 16 black-and-white photos, selections feature a wide range of work with an emphasis on thrills and chills, including Peter Matthiessen on the great white shark, Edward Marriott on hunting man-eaters off Nicaragua, Richard Fernicola's account of the 1916 shark attacks that inspired Peter Benchley's Jaws, and Jacques Cousteau's studies of the creatures.

This book reviews the current status of, and threats to, shark populations globally with special reference to the basking shark and the great white shark. This book outlines why sharks are a valuable resource, identifies threats to sharks and where they occur and reviews what we need to know about sharks in order to protect them. Fisheries management procedures are investigated to target areas requiring future research and implementation. Conservation initiatives, legislation, and international agreements are reviewed and future measures suggested. Case histories on the basking shark and the great white shark detail threats specific to these species and identify research and management requirements.

In his award-winning book WATER, Marq de Villiers provides an eye-opening account of how we are using, misusing, and abusing our planet's most vital resource. Encompassing ecological, historical, and cultural perspectives, de Villiers reports from hot spots as diverse as China, Las Vegas, and the Middle East, where swelling populations and unchecked development have stressed fresh water supplies nearly beyond remedy. Political struggles for control of water rage around the globe, and rampant pollution daily poses dire ecological theats. With one eye on these looming crises and the other on the history of our dependence on our planet's most precious commodity, de Villiers has crafted a powerful narrative about the lifeblood of civilizations that will be "a wake-up call for concerned citizens, environmentalists, policymakers, and water drinkers everywhere" (Publishers Weekly).

With its spectacular beaches and charming towns, Cape Cod is known around the world as a vacation spot and a summer retreat for the well-to-do. But there is another Cape Cod, a hidden, hardscrabble, year-round world whose hunter-gatherer economy dates back to the Bay Colony. The world of the independent fisherman is one of constant peril, of arcane folkways and expert knowledge, of calculated risk and self-reliance -- and of freedom won daily through backbreaking, solitary work. It is a way of life deep in the American grain. Haunted by the numbers of family fishermen who have recently been forced to abandon the profession, Richard Adams Carey spent a year among a handful of men who stubbornly refuse to do so. Reminiscent of the work of William Warner and Joseph Mitchell, AGAINST THE TIDE is a masterly profile of four New England fishermen in which every page opens onto something more profound: maritime history, maritime ecology, and the poetic celebration of a special American place.
