From the more than one million square miles of the six eastern provinces of Canada 154 species of freshwater fishes have been reported. This edition of Freshwater Fishes of Canada provides the game and commercial fisherman and the naturalist with detailed information regarding these fishes, and assists in the accurate identification of the various species. The species are arranged in order of development: primitive first and the more highly specialized fishes last. Each description includes a picture, a list of other common names, the distinguishing features, size, habitat, life history and habits, food, and additional comments. Technical language has been avoided wherever possible but with no loss of accuracy. In this second edition the author has employed a system of keys for easier identification of families, and of the individuals in the two largest and most difficult species, the trout and minnow groups.

This 2-volume set is written by the grandfather of Charles Darwin. The purpose of the books is to reduce the facts belonging to animal life into classes, orders, genera, and species; and, by comparing them with each other, to unravel the theory of diseases.

Over the past hundred years, gulls have been brought ashore by modernity. They now live not only on the coasts but in our slipstream following trawlers, barges, and garbage trucks. They are more our contemporaries than most birds, living their wild lives among us in towns and cities. In many ways they live as we do, walking the built-up world and grabbing a bite where they can. Yet this disturbs us. We've started fearing gulls for getting good at being among us. We see them as scavengers, not entrepreneurs; ocean-going aliens, not refugees. They are too big for the world they have entered. Their story is our story too. Landfill is the original and compelling story of how in the Anthropocene we have learned about the natural world, named and catalogued it, and then colonized it, planted it, or filled it with our junk. While most other birds have gone in the opposite direction, hiding away from us, some vanishing forever, gulls continue to tell us how the wild can share our world. For these reasons Landfill is the nature book for our times, groundbreaking and genre-bending. Without nostalgia or eulogy, it kicks beneath the littered surface of the things to discover stranger truths.

We live in the age of big companies where rising levels of power are concentrated in the hands of a few. Yet no government or organisation has the power to regulate these titans and hold them to account. We need big companies to share their power and we, the people of the world, need to reclaim it. In Competition is Killing Us, top business and competition lawyer Michelle Meagher establishes a new framework to control capitalism from the inside in order to make it work for the many and not just the few. Meagher has spent years campaigning against these multi-billion and trillion dollar mammoths that dominate the market and prioritise shareholder profits over all else; leading to extreme wealth inequality, inhumane conditions for workers and relentless pressure on the environment. In this revolutionary book, she introduces her wholly-achievable alternative; a fair and comprehensive competition law that limits unfair mergers, enforces accountability and redistributes power through stakeholder governance.

Understanding the history and philosophy of biological systematics (phylogenetics, taxonomy and classification of living things) is key to successful practice of the discipline. In this thoroughly revised Third Edition of the classic Biological Systematics, Andrew V. Z. Brower and Randall T. Schuh provide an updated account of cladistic principles and techniques, emphasizing their empirical and epistemological clarity. Brower and Schuh cover: -the history and philosophy of systematics -the mechanics and methods of character analysis, phylogenetic inference, and evaluation of results -the practical application of systematic results to: -biological classification -adaptation and coevolution -biodiversity,and conservation -new chapters on species and molecular clocks Biological Systematics is both a textbook for students studying systematic biology and a desk reference for practicing systematists. Part explication of concepts and methods, part exploration of the underlying epistemology of systematics, This third edition addresses why some methods are more empirically sound than others.

The Fishes of the Western North Atlantic series, which began publication in the 1940s by Yale University's Sears Foundation for Marine Research, was from its beginnings conceived to synthesize and make accessible the wealth of information in widely scattered published accounts of the fish fauna of the region for both the layman and the specialist, presenting critical reviews rather than compilations. These reference works are still considered valuable and of interest today to both general audiences and the academic community. As described in the Preface to the first volume, the series was "written on the premise that it should be useful to those in many walks of life-to those casually ... interested ..., to the sportsman ..., to the fisherman ..., as well as to the amateur ichthyologist and the professional scientist." These books remain authoritative studies of the anadromous, estuarine, and marine fishes of the waters of the western North Atlantic from Hudson Bay southward to the Amazon, ranking as primary references for both amateurs and professionals interested in fishes, and as significant working tools for students of the sea.

Part One, the inaugural volume in the Fishes of the Western North Atlantic series, describes lancelets, hagfishes, lampreys, and sharks. Specialist authorships of its sections include detailed species descriptions with keys, life history and general habits, abundance, range, and relation to human activity, such as economic and sporting importance. The text is written for an audience of amateur and professional ichthyologists, sportsmen, and fishermen, based on new revisions, original research, and critical reviews of existing information. Species are illustrated by exceptional black and white line drawings, accompanied by distribution maps and tables of meristic data. Distributed for the Yale Peabody Museum of Natural History

For centuries orchids have been among the most popular of plant families, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers. The Genera Orchidacearum series represents a robust and natural classification of the orchids, something that has eluded plant scientists and orchid enthusiasts for years. The editors, who are all distinguished orchid specialists, incorporate a wealth of new DNA data into a truly phylogenetic classification, identifying the areas and taxa that merit additional work. To this end, they have invited several international specialists to contribute in their particular areas of expertise. Each volume provides comprehensive coverage of one or two orchid subfamilies, and the series as a whole will be an indispensable reference tool for scientists, orchid breeders, and growers. Orchidaceae is the largest monocotyledon family and perhaps the largest plant family in terms of number of species, approximately 25,000. Although the fossil record is limited, active molecular research in recent years has unravelled many of the complexities and phylogenetics of this cosmopolitan plant family. This sixth and final volume treats 140 genera in tribes Dendrobieae and Vandeae of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, palynology, cytogenetics, phytochemistry, phylogenetics, pollination, ecology, and economic uses. Cultivation notes are included for those genera known to be in hobbyist collections. Genera are beautifully illustrated with line drawings and colour photographs. An Addendum updates a few generic accounts published in past volumes. A cumulative glossary, list of generic synonyms with their equivalents, and list of all series contributors round out this final volume in the series.

In this revision of the calanoid copepod family Heterorhabdidae, 7 genera and 59 species are recognized, and 25 species are described as new. Included are keys to the genera and descriptions and illustrations of all species. A hypothesis of phylogenetic relationships is presented, and the geographic distribution of the species is discussed.

Phylogenetic Systematics: Haeckel to Hennig traces the development of phylogenetic systematics against the foil of idealistic morphology through 100 years of German biology. It starts with the iconic Ernst Haeckel-the German Darwin from Jena-and the evolutionary morphology he developed. It ends with Willi Hennig, the founder of modern phylogenetic systematics. Written in English, the book presents a unique perspective on a vast body of German biological literature. The book also offers a perspective on German biology in the Third Reich. The author looks at how idealistic morphology and phylogenetic systematics represented two antagonistic traditions in German biology, the first organicist-holistic, the latter empiricist-positivistic. In addition, he explains the ways in which both traditions acquired socio-political and ideological connotations, culminating in their accommodation to different strands of Nazi ideology. The book's nine chapters summarize a century of the conceptual development of systematics, describe both the history and philosophy of phylogenetic approaches to the understanding of the history of life, examine the role of important people such as Haeckel, Gegenbauer, Portman, von Bertalanffy, Stresemann, and Hennig, and critically evaluate the impact and influence of Nazism on evolutionary biology. Chapter titles include: The Evolutionary Turn in Comparative Anatomy; Of Parts and Wholes; The Turn against Haeckel; The Rise of Holism in German Biology; The Rise of German ("Aryan") Biology; Ganzheitsbiologie; The Ideological Instrumentalization of Biology; A New Beginning: From Speciation to Phylogenetics; and Grundzuge: The Conceptual Foundations of Phylogenetic Systematics.

Ernst Mayr is perhaps the most distinguished biologist of the twentieth century, and "Systematics and the Origin of Species" may be one of his greatest and most influential books. This classic study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles and correlating the ideas and findings of modern systematics with those of other life science disciplines. This book is one of the foundational documents of the "Evolutionary Synthesis." It is the book in which Mayr pioneered his new concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography, and life history. In his new introduction for this edition, Mayr reflects on the place of this enduring work in the subsequent history of his field.

The purpose of this volume is to emphasize the fact that biological trace element research is a multidisciplinary science which requires a prudent combination of biological insight and analytical awareness. The text frequently stresses that accurate measurements on biologically and analytically "valid" samples hold the key for success in future investigations. It reminds the analytical scientists and the life sciences researchers that their perceptions should extend beyond conventional limits - namely, the former as generators of data and the latter as interpreters of those findings. This book enables the reader to understand the intricacies of elemental composition studies in biological systems, and also provides a valuable source of information to biologists, biochemists, physicians, nutritionists and related scientific workers who intend to draw meaningful conclusions from the analytical findings.
