Download or read book Examination of Speckled Dace Abundance Biology and Habitat in the Canadian Range written by Adam Roy Batty and published by . This book was released on 2010 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Speckled dace, Rhinichthys osculus, a small cyprinid species, was listed as endangered under the Canadian Species at Risk Act (SARA) in 2009. This species exists throughout the western United States, but in Canada it lives in the Kettle, West Kettle, and Granby Rivers in southern British Columbia (BC). I conducted field work in 2008 to assess the abundance, range, biology, and habitat use of this species. I estimated that there were 940,000 mature Speckled dace (90% confidence interval 412,000 - 1,955,000) in the watershed in 2008, a much larger number than previous estimates. I found that the species is longer-lived than previously thought, up to age 7-years. I recommend that the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and the BC Conservation Data Centre re-assess this species, and that a procedure for setting conservation priorities be developed within SARA, similar to the BC Conservation Framework.

Download or read book Freshwater Meiofauna written by Simon D. Rundle and published by . This book was released on 2002 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiofauna are a diverse and numerous component of the fauna in freshwater ecosystems, but have been mostly ignored by freshwater scientists. Freshwater Meiofauna aims to raise the awareness of this enigmatic, microscopic component of the freshwater biota, by providing the first-ever, comprehensive review of their biology and ecology. The first section of the book gives indepth accounts of the systematics, morphological characteristics, life histories and ecological requirements of the main freshwater meiofaunal taxa (i.e. microturbellarians, rotifers, gastrotriches, nematodes, water mites, microcrustaceans and tardigrades). The second section then takes an integrated approach to review the current state-of-play in meiofaunal ecological research in freshwaters, addressing important issues, such as the importance of meiofaunal taxa in the trophic dynamics of freshwater ecosystems and the process underpinning the distribution patterns observed in meiofaunal assemblages. This book should appeal to a wide range of freshwater scientists, including novices in the study of freshwater meiobenthology and established researchers in freshwater ecology, for whom the meiofauna represent an unopened "black box". Our ultimate goal is that this book will serve to promote the idea that the zoology of freshwater habitats concerns more than just fish, macroinvertebrates and microbes.

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.
Download or read book The Los Angeles River written by Blake Gumprecht and published by JHU Press. This book was released on 2001-04-30 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.
