This book was released on 2016-08-01 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Some Effects of Ddt on the Guppy and the Brown Trout Limited observations on growth and repro duction indicated that exposure to ddt did not prevent reproduction in guppies in the first 30 days of chronic exposure, but many of the guppies born in ddt were dead or died within several hours. The survival rate was lower for those born in ddt than for those born in untreated water. The data, however, were not sufficient to make definite conclusions. Observations in the literature indicate that after the first litter, insecticides will inhibit reproduction. The cause of the death of guppies in aquaria kept under con trolled conditions needs to be ascertained before the effects of one dosage of ddt on reproduction can be determined.developed in the fish first exposed to 010 and 0056 ppm ddt.

Book Synopsis Some Effects of DDT on the Guppy and the Brown Trout by : Susan Frances King
Download or read book Some Effects of DDT on the Guppy and the Brown Trout written by Susan Frances King and published by . This book was released on 1962 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Editor's note: This paper was prepared under the direction of Assistant Professor Kathryn M. Eschenberg, Mount Holyoke College and was accepted by the Faculty in partial fulfillment of the requirements for the degree of Bachelor of Arts with Honor, 1961. Despite certain limitations, described below, the paper (somewhat condensed from the original) has been accepted for publication because (1) it is an unusual and excellent study by an undergraduate, and (2) so little information is available on the subject treated. Biometricians may criticize the paper from the standpoint of small numbers and need for replication. One reviewer says: "One of the most interesting observations related to the apparent increase in resistance following exposure to effectively sublethal levels. Part of the increase, but likely only part, was due to the previous selective killing of weaker individuals. Good experimental procedure would require that this test be repeated, with parallel series of previously unexposed fish....There is need for a replicated study of numbers of young born to guppies held in DDT, especially because the numbers are so small." It is the Editor's hope that the limitations of the paper may stimulate further work in this important area.

Book Synopsis Biomonitoring of Trace Aquatic Contaminants by : David J.H. Phillips
Download or read book Biomonitoring of Trace Aquatic Contaminants written by David J.H. Phillips and published by Springer Science & Business Media. This book was released on 1994 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, researchers wishing to identify contaminated areas in aquatic environments generally took water samples, and analysed them badly (as we have since discovered) for a few "pollutants" which were of topical note at the time (and which could be quantified by the methods then available). Today, the use of aquatic organisms as biomonitors in preference to water analysis has become commonplace, and many national and interna tional programmes exist around the world involving such studies. We believe that this trend will continue, and have complete faith in the methodology (when it is employed correctly). We hope that the following text assists in some part in attaining this goal, such that the quality of our most basic global resource -water - is adequately protected in the future. DAVE PHILLIPS, PHIL RAINBOW England, March 1992 vii Acknowledgements Our thanks for contributions to this book are due to several individuals and groups, for varying reasons. Firstly, a co-authored book is always a triumph, and we trust that the following text is an acceptable compromise of the views of two individual authors, on a complex and developing topic. Secondly, many of the ideas herein have crystallised over the last two decades as the field has grown, and we are individually and collectively grateful to a number of researchers for their insight and assistance.
Book Synopsis Animal Biomarkers as Pollution Indicators by : David B. Peakall
Download or read book Animal Biomarkers as Pollution Indicators written by David B. Peakall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.

Download or read book Ecology written by Charles J. Krebs and published by Benjamin-Cummings Publishing Company. This book was released on 2001 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.
