WINNER of the 2019 PEN/E.O. Wilson Literary Science Writing Award Washington Post "50 Notable Works of Nonfiction" Science News "Favorite Science Books of 2018" Booklist "Top Ten Science/Technology Book of 2018" "A marvelously humor-laced page-turner about the science of semi-aquatic rodents.... A masterpiece of a treatise on the natural world."-The Washington Post In Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of "Beaver Believers"-including scientists, ranchers, and passionate citizens-recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world's most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it's about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

Multiple use of natural waters and watersheds poses many practical problems, some of which are clearly limnological, relating for example to carrying capacities oflakes, deterioration of water quality and fisheries management. It is thus important to consider limnological aspects when making decisions in the field of water management. To further this attitude the Finnish Limnological Society considered 'Lakes and Water Management' to be a suitable theme for the Society's Jubilee Symposium, held in Helsinki on 22-23 September, 1980 at the Viikki Campus of the University of Helsinki, to mark the Society's 30th Anniversary. The Finnish Limnological Society has arranged nationallimnological symposia everyone or two years. The papers presented at these symposia have been published in the series 'Limnologisymposion' (in Finnish or Swedish, with short summaries in an internationally spoken language). Due to financial difficulties, the series was terminated as of the symposium in 1979. When preparing the 30th Anniversary of the Finnish Limnological Society, the Governing Board of the Society decided to arrange an international symposium on a theme relevant to modern limnology both in Finland and elsewhere. The selected results of the successful meeting on lakes and water management, which was attended by 220 people from 7 countries, are presented in this volume.

Discover the incredible diversity of life within our seas and learn how we can all play a role in protecting and conserving it. Our seas are home to an abundance of fascinating creatures and stunning habitats. From spectacular kelp forests to intricate rocky reefs and from mud plains to open ocean, the British Isles have a diversity of marine ecosystems that rival those seen on any nature documentary. Yet, for generations, we have been slowly suffocating life beneath the waves. Decades of unsustainable exploitation, endless pollution and a warming climate have had a devastating effect on our marine habitats. However, it's not too late to make a difference and change course. Written in collaboration with the Wildlife Trusts, Britain's Living Seas provides a user-friendly and richly illustrated guide to coasts around the British Isles, uncovering the diversity of life within a range of marine habitats and the life-giving services that they provide us. Outlining how their very existence is under threat, marine biologist Hannah Rudd presents an alternative and sustainable future for the management of our seas. We can all do our bit as individuals too. Through practical steps such as re-thinking what we eat, our relationship with plastic and how we spend our money, we can become marine conservationists in our everyday lives and help to create a healthier future for our oceans. Everyone can discover more about the wonders within the waters that surround us and play a part in rebuilding our connection with the natural world.

A thrilling guided tour through the world of sharks and their relationship with human communities around the globe.
From Belize to South Africa, from Shanghai to Bimini, we see that sharks are still the object of an obsession that may eventually lead to their extinction. In this eye-opening adventure that spans the globe, environmental journalist Juliet Eilperin investigates the fascinating ways different individuals and cultures relate to the ocean's top predator. Along the way, she reminds us why, after millions of years, sharks remain among nature's most awe-inspiring creatures. With a reporter's instinct for a good story and a scientist's curiosity, Eilperin offers us an up-close understanding of these extraordinary, mysterious creatures in the most entertaining and illuminating shark encounter you're likely to find outside a steel cage.

This volume is based on the proceedings of a conference held at Florida State University in April, 1978. This conference was supported by the Florida State University Graduate Research Council, the Department of Biological Science (F. S. U. ), and the Center for Professional Development and Public Service. Particular recogni tion should be made of the efforts of Dr. Anne Thistle in the organization of the conference and the completion of this book. Julia K. White and Sheila Marrero produced the typescript. The principal objective of the conference was to assemble a group of marine scientists from diverse disciplines to discuss the state of marine ecology with particular attention to new research directions based on previous studies. Emphasis was placed on the integration of different research approaches and on the application of established procedures to various environmental problems. An effort was made to eliminate traditional disciplinary boundaries which often hinder our understanding of marine systems. There was generally wide latitude for review and speculation concerning such topics as physico-chemical processes, productivity and trophic interactions, population distribution and community structure, and natural or anthropogenic disturbance phenomena. Throughout, the usual miniaturization of the scope of discussion was subordinate to a frank appraisal of the present status of marine research. Although many introductory ecological texts stress the so called ecosystem approach, individual marine research projects seldom encompass this broad course. There is, in fact, a real need for system-wide studies at both the theoretical and applied levels."

The idea of convening an international workshop on hypertrophic ecosystems originated during the 20th S.I.L. Congress in Copenhagen. A group of about 30 delegates met there in an informal gathering to discuss the specific problems of lakes which have reached a noxious stage of eutrophication. This ad hoc group realized its own specific identity within the limnological community and suggested the organization of a specialized future meeting on hypertrophic ecosystems. After two years of preparatory work, the workshop was fmally held in Vaxjo, Sweden, between September 10 and 14, 1979, on the premises of the University campus. The Institute of Limnology, University of Lund (Professor Sven Bjork), undertook the task of host and organizer. The City ofVaxjo and the University of Lund co-sponsored the event, which was held under the auspices and patronage of the Societas Internationalis Limnologiae. The objective of the workshop was to seek better understanding of highly-eutrophic, disturbed and unstable aquatic ecosystems (lakes, reservoirs and ponds developing noxious algal and bacterial blooms, fluctuating in their water quality on a daily and seasonal scale, producing gases, off-flavor and toxic substances, experiencing periodic anoxia and massive fish kills, etc.), Le., systems requiring corrective measures and new concepts for their solution beyond those generally accepted for 'normal' eutrophic systems.

The Reef Guide documents some 800 reef fishes and invertebrates found along the east and south coasts of southern Africa.

Following on the success of Dennis King’s earlier two titles, this impressive new guide features 578 species of fish and includes sections on anemones, starfish, snails, crabs and shrimps.

Full-colour photographs and descriptive text for each species, along with useful and interesting information, make for easy identification. While focusing on southern Africa, the book is also applicable to the entire east coast of Africa, as well as the islands of the western Indian Ocean – Seychelles, Mauritius, Reunion, Madagascar, the Comoros and the Maldives.

It is the perfect take-along guide for travelers and nature enthusiasts of all ages. Made in the USA.

A riveting journey into the bizarre world of the Asian arowana or "dragon fish" the world's most expensive aquarium fish-reveals a surprising history with profound implications for the future of wild animals and human beings alike. The Dragon Behind the Glass tells the story of a fish like none other: a powerful predator dating to the age of the dinosaurs. Treasured as a status symbol believed to bring good luck, the Asian arowana is bred on high-security farms in Southeast Asia and sold by the hundreds of thousands each year. In the United States, however, it's protected by the Endangered Species Act and illegal to bring into the country-though it remains the object of a thriving black market. From the South Bronx to Singapore, journalist Emily Voigt follows the trail of the fish, ultimately embarking on a years-long quest to find the arowana in the wild, venturing deep into some of the last remaining tropical wildernesses on earth. In an age when freshwater fish now comprise one of the most rapidly vanishing groups of animals on the planet, Voigt unearths a paradoxical truth behind the dragon fish's rise to fame-one that calls into question how we protect the world's rarest species. An elegant exploration of the human conquest of nature, The Dragon Behind the Glass revels in the sheer wonder of life's diversity and lays bare our deepest desire-to hold onto what is wild.

Sea squirts and sponges are found in most seafloor habitats around the coasts of Britain and Ireland. Despite being the dominant life forms in many areas, these two groups of under-recorded marine animals are often confused with one another, and most divers and snorkellers can recognise and name very few species. In fact, around 500 species of Ascidiacea (sea squirts) and Porifera (sponges) have been described so far in British and Irish seas, corresponding to over 4% of the world's total. This book is recommended reading for anyone who wants to identify and discover more about these fascinating and diverse animals. Rather than relying on the characteristics of preserved specimens, this guide uses marine photography and detailed underwater observations to concentrate on in situ features, allowing you to record species without collecting them. Most sea squirts found in Britain and Ireland's shallow waters are included, together with the most easily recognised sponges. Whether you are a student, a diver, a rockpooler or simply an enthusiast, this is an essential companion. aAA AA Over 115 species described in detail, with in situ photographs to help with underwater recognition aAA AA Information on size, depth, habitat and distribution aAA AA Key distinguishing features and areas of confusion in identification highlighted aAA AA Details of body structure, life histories, digestive and reproductive processes aAA AA Information about predators, interactions between species, non-native and problem invasive species

Wyl Menmuir's The Draw of the Sea is a beautifully written and deeply moving portrait of the Cornish Coast and the people who make their livings there, examining the ephemeral but universal pull the sea holds over the human imagination. 'A beautiful portrait of lives shaped by the swell of ocean and tide - a powerful salt-thread of connection' - Raynor Winn, author of The Salt Path Since the earliest stages of human development, the sea has fascinated and entranced us. It feeds us, sustaining communities and providing livelihoods, but it also holds immense destructive power which can take all those away in an instant. It connects us to far away places, offering the promise of new lands and voyages of discovery, but also shapes our borders, carving divisions between landmasses and eroding the very ground beneath our feet. In this beautifully-written meditation on what it is that draws us to the waters' edge, author Wyl Menmuir tells the stories of the people whose lives revolve around the sea in the Cornish community where he lives. In twelve interlinked chapters, Menmuir explores the lives of local fishermen steeped in the rich traditions of a fishing community, the beachcombers who wander the shores in search of the varied objects which wash ashore and the stories they tell, and all number of others who have made their lives on the beautiful Cornwall coast. In the specifics of these livelihoods and their rich histories and traditions, Wyl Menmuir captures the universal human connection to the sea. Into this seductive tapestry, Wyl weaves the story of how the sea has beckoned, consoled and restored him. This book is a meaningful and moving work into how we interact with the environment around us, and how it comes to shape the course of our lives. As unmissable as it is compelling, as profound as it is personal, this must-read book will delight anyone familiar with the intimate and powerful pull which the sea holds over us.

Discover the pros secrets for catching more and bigger muskies. They don't call it the Fish of Ten Thousand Casts for nothing. The challenge of catching muskie is not only finding them, but also figuring out their attitude and what presentation might work--today. To find success tomorrow, you'll probably need a different location, attitude, and lure.
Pro muskie "hunters" Jack Burns and Rob Kimm share their own experience as well as that of the many other muskie anglers with whom they've worked and fished over the years. They cover the basic biology of muskies and how you can use that knowledge to catch more and bigger fish. They discuss fishing tackle, release techniques, reacting to follows, doing figure eights, triggering strikes, and much more.
In this expertly written book you'll find examples of on-the-water tactics and strategies covering a wide range of situations. More important, you'll develop an understanding of the why behind a particular strategy and how to adapt to different water and weather conditions throughout the year.

Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework.

The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems.

Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University.

Reviews
Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.'
Simon Harrison in Journal of Ecology, 86
The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.'
Wolf Mooij in Aquatic Ecology, 32

With over 550 species and almost 700 photographs all captured in situ, this book represents the most comprehensive field guide to the reef fishes of Seychelles currently available. The general introduction discusses Seychelles' geography and coral reefs, followed by the taxonomy, classification and nomenclature of the species, fish diversity in Seychelles, endemic and endangered fishes, and fish anatomy. The species descriptions cover identifying features, size, biology and distribution.

Each year, thirteen million anglers enjoy the sport of saltwater angling in the United States, generating an estimated $30 billion in sales and supporting nearly 350,000 jobs. Recreational saltwater fishing, however, can significantly impact species of concern-species overfished or experiencing overfishing. Traditional angling controls bag and size limits and restricted seasons have fallen short in controlling fishing impacts and reducing conflicts among fishing and non-fishing interests. Evolving Approaches to Managing Marine Recreational Fisheries offers ways of overcoming such problems while providing anglers and the recreational service industry greater regulatory flexibility to enjoy the fruits of sportfishing. It features fourteen internationally recognized fishery experts presenting the pros and cons of using individual fishing quotas (IFQs), game tags, and angler management organizations (AMOs) in managing marine recreational fisheries, presenting both theoretical and practical solutions to help move recreational fisheries management to a new and improved level."

The coelacanth (see-lo-canth) is no ordinary fish. Five feet long, with luminescent eyes and limb like fins, this bizarre creature, presumed to be extinct, was discovered in 1938 by an amateur icthyologist who recognized it from fossils dating back 400 million years. The discovery was immediately dubbed the "greatest scientific find of the century," but the excitement that ensued was even more incredible. This is the entrancing story of that most rare and precious fish -- our own great-uncle forty million times removed.

Beaches, marshes, mangroves; cliffs, deserts, forests; bays, deltas, estuaries - coastlines take many different forms and are put to very different uses. From deserted beaches to busy ports, from pretty fishing villages to a surfers' paradise, a salt marsh to a ship-breakers' yard, Coasts celebrates where the land meets the sea. From beautiful coastal paths to the shipwrecks left high and dry in the Aral Sea, from world famous locations such as Copacabana Beach in Brazil and Big Sur in California to the little explored coastlines of Yemen and Oman, from Algeria to Antarctica, the Amalfi Coast to the Dead Sea, the book celebrates a huge range in coastlines from all around the world. Including nature reserves and tourist resorts, rugged landscapes and desert island tranquility, fjords and fossils, eroding cliffs to whole towns lost to the waters, the book explores coastlines in all climates and conditions around the globe. Presented in a landscape format and with captions explaining the story behind each entry, Coasts is a stunning collection of images and stories.

Winner Rubery Book Award; Highly Commended, British Book Design & Production Awards. This beautiful and unusual book brings together a year's wanderings along Britain's shores with compelling stories of their natural history, geology and evolution - from ancient myth to current science - and the author's striking contemporary photography. Whether paddling through the shallows, sheltering in a sea cave or crouching on a cliff in a hailstorm, we are taken on a journey of fascinating diversions. Against a backdrop of the shifting seasons, weather and tides, there are mermaid's purses, hag stones and by-the-wind sailors, alongside stories of wind-sellers and nineteenth century fossil hunters, the evolution of whales and Lego dragons lost at sea. As the threads draw together there is the sense that a walk on the beach, with all its chance finds and everyday wonders, stretches both back into the deep past and ahead into the uncertain future of our oceans. Above all, we are inspired to go out and explore for ourselves, reminded of the pleasures of discovery, and of looking and listening more closely.

In its extraordinary debut, Safari, introduced the world to Photicular technology. The cheetah bounded, the African elephant flapped its ears and readers could not believe their eyes. Now the creators of Safari take their work a step further. Ocean offers not only a refinement of inventor Dan Kainen s Photicular technology, but a subject undulating creatures of the deep perfectly suited to the immersive visual pleasure of the process. Ocean is like being on a dive. Open the book, and the reader is swept into the magic of an underwater world, face-to-face with a floating Yellow-Banded Sweetlips; with a glow-in-the-dark Deep-Sea Anglerfish; with a Sea Horse swaying in balletic motion; with a Sand Tiger Shark gliding along the ocean floor, its gaze haunting, its hook-toothed mouth gulping open and closed. The text by Carol Kaufmann enchants with its descriptions of coral reefs; a journey on Alvin, the 17-ton submersible; and a meditation on our oceans. Then, for each creature, she writes a lively and informative essay, along with vital statistics size, habitat, range, diet, and more. The Photicular process uses an innovative lenticular technology, sliding lenses, and original four-color video imagery. The result is like a movie in your hands the dance of life in a book."
