The Salvelinus, the Sockeye, and the Egg-Sucking Leech: Abundance and Diversity in the Bristol Bay Drainage (from the Eyes of an Angler) is the fourth book in Matthew Dickerson' s Heartstreams series, published by Wings Press. This exciting ramble among the remote and beautiful mountains, lakes, and rivers of around Alaska' s Bristol Bay is full of encounters with bears, caribou, and other wildlife. But the heart of the book is Dickerson' s exploration of native trout, river ecology, and the joys of experiencing wild places and fish by casting flies among them. This volume focuses on rivers and lakes in Alaska' s Bristol Bay drainage, and on the native fish that inhabit those waters, from the abundant sockeye salmon species to the Salvelinus genus, which includes the stunningly beautiful Dolly Varden char as well as its cousin the Arctic char, the northernmost freshwater fish species in the world. Although the book explores some of the environmental threats facing these waters, the stories are also full of hope, delight, and awe. Though not a science text, it is well-informed by science as well as by the author' s careful eye. The book also includes photographs from Alaskan bush pilot and lodge owner Glen Alsworth Jr., who has lived his whole life in a small village in the middle of a national park in the Bristol Bay drainage. This volume concludes the Wings Press Heartstreams series, in which Dickerson has used fly-fishing expeditions to study the ecological health of trout and their streams from the Northeast to Apalachia to the Desert Southwest to the northern Rockies to Alaska.
From the Arctic to Bristol Bay, this book covers all the fabulous fishing opportunities throughout Alaska. With this resource, anglers can fly into Anchorage, rent a camper, and be catching trophy salmon and trout within hours of arrival. Includes 109 detailed river and lake maps--a big book for a big state.
"Drawing from a viewpoint informed by C.S. Lewis and J.R.R. Tolkien, Matthew Dickerson and David O'Hara explore the influence and importance of ancient biblical narrative, Greek mythology, Arthurian legend, and other works of "Faerie" on our literary culture. They discuss how myth and fantasy offer profound insights into truth and provide sound assessment of modern authors such as Philip Pullman, Walter Wangerin, and J.K. Rowling."--BOOK JACKET.
Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

An endearing animal fantasy story from master storyteller Dick King-Smith. The story begins with a mysterious egg washed up on a Scottish beach, the morning after a great storm. Kirstie and her brother Angus find the egg and take it home. The next day it has hatched into a tiny greeny-grey creature with a horse's head, warty skin, four flippers and a crocodile's tail. The baby sea monster soon becomes the family pet - but the trouble is, it just doesn't stop growing!
This work offers detailed information on British prosobranch molluscs.
