Book excerpt: Our Landscape Heritage provides an overview of the history and ecological makeup of the landscapes of New Brunswick to help ecological seekers starting out with basic knowledge about geology, soils, climate, and vegetation, to better understand why plants and animals are today distributed as they are. Part I outlines the rationale and history of ecological land classification (ELC) in New Brunswick, and presents basic scientific concepts and facts that help the reader to interpret the information that follows. Part II, Portrait of New Brunswick Ecoregions and Ecodistricts presents a detailed look at the variety and distribution of ecosystems across the geographic expanse of New Brunswick. Each of the seven chapters of Part II provides a high level description of the ecoregion, followed by detailed descriptions of each ecodistrict within the ecoregion.--Includes text from document.

As wellas being an important class biologically and ecologically, many ofthe bivalves are fished and cultured commercially (e.g. mussels,oysters, scallops and clams) in a multi-billion dollar worldwideindustry. Elizabeth Gosling who has a huge wealth of research, teachingand hands on experience working with bivalves, has written alandmark book that will stand for many years as the standard workon the subject. Chapters in Bivalve Molluscs covermorphology, ecology, feeding, reproduction, settlement andrecruitment, growth, physiology, fisheries, aquaculture, genetics,diseases and parasites, and public health issues. A fullunderstanding of many of these aspects is vital for all thoseworking in bivalve fisheries and culture. An essential purchase for anyone concerned with this importantclass of animals, copies of Bivalve Molluscs should be onthe shelves of biologists, ecologists, environmental scientists,fisheries scientists and personnel within the aquaculture industry.Copies of the book should be available in all libraries andresearch establishments where these subjects are studied ortaught.

Download or read book The Atlantic Salmon in the History of North America written by R. W. Dunfield and published by Fisheries and Oceans, Scientific Information and Publications Branch. This book was released on 1985 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized. Appendix A: Historical methods of packing salmon.
