Download or read book The American Darters written by Robert A. Kuehne and published by University Press of Kentucky. This book was released on 2021-11-21 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: The darters are a fascinating group of colorful and diminutive freshwater fish whose beauty rivals that of the tropical reef fishes. Native only to North America, the darters occur widely, especially in the United States, but are little known to the general public, largely because of their small size—few exceed six inches and some measure a mere one inch at maturity. This book is the first comprehensive guide to the darters, covering all named and several undescribed forms—140 species in all. Each species account includes a synoptic description to aid in separation of similar species and subspecies, a range map, and discussion of the species' distribution, natural heritage, abundance, and scientific name. An illustrated key and glossary will further assist scientists, students, fishermen, and aquarium specialists in identifying darter species. Central to this volume is the series of 144 handsome color photographs illustrating nearly all known darter species and several subspecies. Most of the specimens shown were caught by the authors at sites throughout the United States, Canada, and Mexico, and photographed by them on site using a recently developed technique that captures the full brilliance of the living fish. Because of their importance as indicators of environmental quality, the darters are receiving increasing attention today from scientists and naturalists. Public interest was focused recently on the plight of the snail darter, but many other darter species are either threatened or endangered, and others face an uncertain future as human activities continue to degrade our waterways. All those with an interest in preserving the natural heritage of our rivers and streams will find this comprehensive guide to the darters an invaluable tool.

Book excerpt: The survey procedures which are outlined in this manual aredesigned to acquire basic knowledge of the chemical, physical andbiological conditions of the lakes and streams in Ontario. Themanual has been written to standardize the many methods andtechniques which have been devised over the past several decades. Lakes and streams are dealt with separately. Identification, location definition, mapping, chemical and physical parameters, sampling, documentation and preservation of fish andinvertebrates, and completion of reports are covered.
Download or read book A Primer of Ecological Statistics written by Nicholas J. Gotelli and published by Sinauer. This book was released on 2013-03-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Primer of Ecological Statistics, Second Edition explains fundamental material in probability theory, experimental design, and parameter estimation for ecologists and environmental scientists. The book emphasizes a general introduction to probability theory and provides a detailed discussion of specific designs and analyses that are typically encountered in ecology and environmental science. Appropriate for use as either a stand-alone or supplementary text for upper-division undergraduate or graduate courses in ecological and environmental statistics, ecology, environmental science, environmental studies, or experimental design, the Primer also serves as a resource for environmental professionals who need to use and interpret statistics daily but have little or no formal training in the subject. The book is divided into four parts. Part I discusses the fundamentals of probability and statistical thinking. It introduces the logic and language of probability (Chapter 1), explains common statistical distributions used in ecology (Chapter 2) and important measures of central tendency and spread (Chapter 3), explains P-values, hypothesis testing, and statistical errors (Chapter 4), and introduces frequentist, Bayesian, and Monte Carlo methods of analysis (Chapter 5). Part II discusses how to successfully design and execute field experiments and sampling studies. Topics include design strategies (Chapter 6), a 'bestiary' of experimental designs (Chapter 7), and transformations and data management (Chapter 8). Part III discusses specific analyses, and covers the material that is the main core of most statistics texts. Topics include regression (Chapter 9), analysis of variance (Chapter 10), categorical data analysis (Chapter 11), and multivariate analysis (Chapter 12). Part IV—new to this edition—discusses two central topics in estimating important ecological metrics. Topics include quantification of biological diversity (Chapter 13) and estimating occupancy, detection probability, and population sizes from marked and unmarked populations (Chapter 14). The book includes a comprehensive glossary, a mathematical appendix on matrix algebra, and extensively annotated tables and figures. Footnotes introduce advanced and ancillary material: some are purely historical, others cover mathematical/statistical proofs or details, and still others address current topics in the ecological literature. Data files and code used for some of the examples, as well as errata, are available online.

Download or read book Marine Fisheries Ecology written by Simon Jennings and published by John Wiley & Sons. This book was released on 2013-04-16 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings
