This book was released on 2015 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) has requested an update of the status of River Darter in Canada. This document will follow the three biogeographic zone convention to aid in the transfer of information to the COSEWIC process. As the Department responsible for this species, Fisheries and Oceans Canada (DFO) is required to summarize available information on this species. As many of the Canadian records of River Darter are quite old, in preparation for the COSEWIC status report, DFO revisited many of the historic sites and sampled additional waterbodies, where possible. This manuscript reports on the findings of those targeted surveys, along with incidental captures from across the species range, including an assessment on the distribution of River Darter and its relative abundance, an update of life history characteristics, diet and identification of the characteristics of River Darter habitat.

Download or read book The State of the Nation s Ecosystems written by H. John Heinz III Center for Science, Economics, and the Environment and published by Cambridge University Press. This book was released on 2002-09-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: We all rely on a familiar set of indicators - interest rates, unemployment, inflation, the Dow Jones index, and GDP, for example - to gauge the performance of national economies. No such measures are currently available to describe the environment. This book lays out a blueprint for periodic reporting on the condition and use of ecosystems in the United States. Developed by experts from businesses, environmental organizations, universities, and federal, state, and local government agencies, it is designed to provide policymakers and the general public with a succinct and comprehensive - yet scientifically sound and non-partisan - view of 'how we are doing'. This book should prove invaluable for decision makers in natural resource management and environmental policy in government and environmental organizations, businesses, and trade associations; academics with a research or teaching interest in environmental issues; and the general public interested in the continued well-being of American ecosystems.

Download or read book The Black Tailed Prairie Dog written by John L. Hoogland and published by University of Chicago Press. This book was released on 1995-04 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Black-Tailed Prairie Dog, John L. Hoogland draws on sixteen years of research at Wind Cave National Park, South Dakota, in the United States to provide this account of prairie dog social behavior. Through comparisons with more than 300 other animal species, he offers new insights into basic theory in behavioral ecology and sociobiology. Hoogland documents interactions within and among families of prairie dogs to examine the advantages and disadvantages of coloniality. By addressing such topics as male and female reproductive success, inbreeding, kin recognition, and infanticide, Hoogland offers a broad view of conflict and cooperation. Among his surprising findings is that prairie dog females sometimes suckle, and at other times kill, the offspring of close kin. Enhanced by more than 100 photographs, this book illuminates the social organization of a burrowing mammal and raises fundamental questions about current theory. As the most detailed long-term study of any social rodent, The Black-Tailed Prairie Dog will interest not only mammalogists and other vertebrate biologists, but also students of behavioral and evolutionary ecology.
Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Keys to the species provide fast, accurate identification and allow anglers to determine the species of fish they have just caught. Ideal for everyone interested in the diversity of our world.
Download or read book Precious Heritage written by Bruce A. Stein and published by Oxford University Press. This book was released on 2000-03-16 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
