Book Synopsis Application of a Dichotomous Key to the Classification of Sea Lamprey Marks on Great Lakes Fish by : Mark P. Ebener
Download or read book Application of a Dichotomous Key to the Classification of Sea Lamprey Marks on Great Lakes Fish written by Mark P. Ebener and published by . This book was released on 2006 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document augments the dichotomous key crated by Ebener et al. (2003) with photographs taken during the 2002 and 2003 workshops, and it is intended to help fishery agencies implement the King and Edsall (1979) protocol for classifying sea lamprey marks. Their illustrations represented the "idealized" types and stages of sea lamprey marks in comparison with the more complicated marks often observed in the field. We combined the original King and Edsall (1979) photographic illustrations with photographs made at the five workshops to create this sequel to the 1979 field guide.

Book Synopsis Biology of the Sea Lamprey in Its Parasitic Phase by : Phillip Sheridan Parker
Download or read book Biology of the Sea Lamprey in Its Parasitic Phase written by Phillip Sheridan Parker and published by . This book was released on 1956 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the experimental lampreys were mature and rip after 14 to 18 months of parasitic life. They exhibited signs of irreversible physical degeneration which precedes death. Three specimens were immature at 14, 18, and 26 months in aquariums, thus indicating that under certain conditions, lampreys may extend their parasitic phase.
Book Synopsis Invasive Species in a Globalized World by : Reuben P. Keller
Download or read book Invasive Species in a Globalized World written by Reuben P. Keller and published by University of Chicago Press. This book was released on 2015 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global trade and the spread of human populations have increasingly moved thousands of native animal and plant species across the natural barriers that have kept them ecologically separated for millions of years. Because some of them thrive in their new regions and harm the environment, the economy, and human health, the prevention and management of such invasive species has become a major local, national, and international policy initiative. Yet even though ecologists have been studying the negative (and sometimes positive) environmental impacts of invasive species and trying to curb their proliferation, and even though their work has in some cases stimulated public conversation and policy, politicians have generally ignored their recommendations. As a result, ecologists have achieved limited success in slowing the spread of invasives. They ve been realizing that in order to fully characterize the impacts of these species, they need to engage with other relevant disciplines across the social and legal sciences as well as the humanities. Drawing together a wide variety of ecologists, historians, economists, legal scholars, policymakers, and communication scholars, Invasive Species in a Globalized World aims to facilitate a dialogue among these various disciplines in order to fully understand invasives and stop their spread. Addressing the numerous challenges associated with reducing invasive impacts, the contributors provide direct policy recommendations, strategies for communicating the risks of invasive species, and insight into how public discourse drives our response to these risks."

Book Synopsis Freshwater Biodiversity by : David Dudgeon
Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

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.

Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Book Synopsis The Gastro-Archeologist by : Jeremy Woodward
Download or read book The Gastro-Archeologist written by Jeremy Woodward and published by Springer Nature. This book was released on 2021-02-03 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to understand common conditions such as coeliac disease and Crohn’s disease, one must view the gut in its evolutionary context. This is the novel approach to the gut and its diseases that is adopted in this book. The first part tells the story of the evolution of the gut itself – why it came about and how it has influenced the evolution of animals ever since. The second part focuses on the evolution of immunity and how the layers of immune mechanisms are retained in the gut, resembling the strata revealed in an archeological dig. The final part, ‘The Gastro-Archeologist’, ties the first two together and highlights how understanding the gut and immune system in their evolutionary context can help us understand diseases affecting them. Ambitious in its scope but telling a unique story from a refreshingly novel perspective, the book offers an informative and enjoyable read. As the story of the gut, immunity and disease unfolds, the author aims to endow readers with the same sense of awe and excitement that the subject evokes in him. Difficult concepts are illustrated using simple and colourful analogies, and the main content is supplemented with anecdotes and unusual and amusing facts throughout the book. The book is intended for anyone with an interest in the gut, its immunity and diseases, ranging from school and college biology and biomedical students, to professionals working in the field, and to patients suffering from intestinal diseases who want to understand more about their conditions.
