Charles Darwin was a British naturalist whose theory or evolution by natural selection became the basis of modern theories of evolution. Darwin shocked the Victorians by suggesting that humans and animals shared the same ancestry. The Origin of Species is his most famous work. Darwin was aboard the Beagle in the Indian Ocean when he formulated his theory about the formation of coral reefs. Darwin theorized that coral reefs grew on sinking mountain rims. The delicate coral built up, compensating for the drowning land, so as to remain within optimal heat and lighting conditions.
This document presents the results of the first three monitoring events to track the recovery of a repaired coral reef injured by the M/V Elpis vessel grounding incident of November 11, 1989. This grounding occurred within the boundaries of what at the time was designated the Key Largo National Marine Sanctuary (NMS), now designated the Key Largo NMS Existing Management Area within the Florida Keys National Marine Sanctuary (FKNMS). The restoration monitoring program tracks patterns of biological recovery, determines the success of restoration measures, and assesses the resiliency to environmental and anthropogenic disturbances of the site over time. To evaluate restoration success, reference habitats adjacent to the restoration site are concurrently monitored to compare the condition of restored reef areas with "natural" coral reef areas unimpacted by the vessel grounding or other injury. The monitoring program at the Elpis site includes an assessment of the structural stability of installed limestone restoration boulders, and comparison of the recovery of coral populations, to be performed on the following schedule: nine, ten, twelve, and fifteen years after restoration. Restoration of this site was completed in the summer of 1995 with monitoring planned to begin in following years. However, due to staffing and other logistical constraints, the first biological monitoring event for this site, used as a "pilot project" to establish data collection methods, was delayed until August 2004. In June and July 2005, the second monitoring event took place, and in August 2007, the third. This report presents the quantitative results of the latter two monitoring events.

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.
The primary purpose of this book is to provide for identification of estuarine and coastal fishes that may be encountered by angling, seining, or trawling on the Georgia coast. Sport and commercial species are emphasized, but all groups occurring on the Continental Shelf are discussed. This book will be especially useful to ecologists who need to identify species in order to study community structure within the estuarine and coastal ecosystems. Information on habitats and seasonality will also aid scientists in collecting certain species for research projects.
The largest creatures to inhabit the Earth, whales have long
inspired awe in human beings. Because they spend almost 95 percent
of their time beneath the ocean surface, however, little has been
known about their lives--until recently. With advances in
technology and more intense study, fresh facts are coming to light
about these magnificent mammals, and to be a whale watcher now,
says acclaimed author and wildlife biologist Douglas Chadwick, is
to have a front-row seat to stunning discoveries.
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.
Collected here in this omnibus edition are Henry David Thoreau's most important works including A Week on the Concord and Merrimack Rivers; The Selected Essays of Henry David Thoreau, including Civil Disobedience; and of course, Walden. A Week on the Concord and Merrimack Rivers is both a remembrance of an intensely spiritual moment in Henry David Thoreau's life and a memoriam to his older brother who accompanied him on the trip shortly before his death. Full of fascinating literary musings and philosophical speculations, this book is a true precursor to Walden. The Selected Essays contains nineteen essays (including Civil Disobedience). Thoreau was one of America's best known and most influential writers. His work has helped shape the American Discourse and had a lasting effect on the environmental movement in America. Walden is one of the best-known non-fiction books ever written by an American. It details Thoreau's sojourn in a cabin near Walden Pond, amidst woodland owned by his friend and mentor Ralph Waldo Emerson. Walden was written with expressed seasonal divisions. Thoreau hoped to isolate himself from society in order to gain a more objective understanding of it. Simplicity and self-reliance were Thoreau's other goals, and the whole project was inspired by Transcendentalist philosophy. This book is full of fascinating musings and reflections. As pertinent and relevant today as it was when it was first written.

Self-described as half-teacher, half-naturalist, Dr. Kenneth S. Norris is one of the world s foremost authorities on whales and dolphins, those most appealing creatures with whom we share the planet. Focusing on the spinner dolphins off Hawaii, Norris carries us through his earliest contacts with these graceful animals (including work with Gregory Bateson), his attempts with teams of students to learn about their complex lives in the sea, and finally to the tragic dolphin kill in the yellowfin tuna industry."
On a hot summer's day there could be no quicker transport to the seaside than Trevor Norton's cool and entrancing account of a lifetime's adventures under or near the water. Norton's eye for the bizarre, amazing, and beautiful inhabitants of the oceans, and the eccentric characters who work, study, and live by the shore make his book a wonder-filled experience. An intrepid diver and distinguished scientist, Norton's writing is self-deprecating, very funny, and full of wry and intriguing anecdotes; he is an unfailingly delightful companion. Whether his setting is a bed of jewel anemones in an Irish lough, a giant California cavern shared with sea lions, a mildewed research station, or the glittering coral gardens of Sharm el Sheikh, his captivating prose always finds the mark. Sometimes following the shoreline with earlier beachcombers such as Darwin, John Steinbeck, and George Orwell, Norton also takes the reader to depths where the shapes of creatures living without sunlight defy imagination. Admirers of the gorgeous detail of Rachel Carson's "The Sea Around Us" will revel in Norton's writing, his observations, and irreverent wit.
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.
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.
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 than 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.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.
There is an increasing awareness that rivers need more room in order to safeguard flood safety under climate change conditions. Contemporary river management is creating room in the floodplains and allowing, within certain bounds, natural processes of sedimentation and erosion. One of the aims is to restore dynamic conditions, so as to get a sustainable and more diverse river ecosystem that can cope with floods. This new approach requires understanding of the interaction between the biotic and abiotic components of river systems. More specifically, it requires a better understanding of the interaction between flora and fauna and geomorphological factors. This is the object of investigation of the interdiscipline of biogeomorphology. Modelling biogeomorphological processes in river floodplains is the topic of this thesis.
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.
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.
In Remarkable Shrimps, Raymond T. Bauer explores the evolution, natural history, biological diversity, and commercial importance of caridean shrimps--a fascinating and colorful group of aquatic organisms that inhabit freshwater and marine environments from the tropics to the poles.The biological diversity of carideans encompasses a remarkable array of adaptations in body form and function, coloration, breeding biology, and mating behavior. Carideans' important grooming and antifouling adaptations are examined in detail, and Bauer discusses the structural basis of their coloration, the role of color change in concealment, and other forms of camouflage. Reproductive biology and sexual systems, including hermaphroditism and sex change, are reviewed, and Bauer provides evidence for sex pheromones in the attraction of males to females. Seasonal, latitudinal, and depth variation in life history patterns are also analyzed. The symbiotic relationships of shrimps with invertebrates such as corals, sea anemones, and sea urchins and also with fishes are fascinating phenomena of marine ecosystems. Different views on the ancestry and evolutionary history of carideans are evaluated as a stimulus for further work. The status of caridean fisheries and aquaculture is appraised, and shrimp productivity is explained in terms of life history adaptations. Profiling each of the nearly thirty families of caridean shrimps, Bauer writes in an informal style that is nevertheless rich with precise and useful references. Over one hundred figures and 11 plates with 70 color and half-tone photographs accompany the text. Extensive fieldwork is showcased in life history studies on shrimps, employing both behavioral observations using time-lapse video and experimental work to test hypotheses on mating strategies. |
