Download or read book Essays on the Prosobranchs written by Robert T. Dillon and published by Bookbaby. This book was released on 2019-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume I in this series reported the scientific results from our survey of the freshwater gastropods of United States Atlantic drainages, Georgia to the New York line. In the preface to that volume, I mentioned that during the 20 years over which the FWGNA Project has unfolded, I developed the habit of sending regular emails to an expanding list of collaborators, a practice which ultimately evolved into an internet blog. Those emails and blog posts have sometimes contained important supplementary information on the biology of the fascinating organisms toward which the FWGNA Project has been directed, as well as historical background, context, and rationale for various methodological and taxonomic decisions made in Volume I.Volume II collected 29 essays on the freshwater pulmonate gastropods. Here in Volume III we have assembled 37 essays on the evolutionary biology and systematics of the prosobranchs, published online between 2006 and 2019. These essays have been edited rather heavily from the form in which they were originally posted, in many cases, and re-ordered into subthemes. Essays 1 - 27 focus on the pleurocerid gastropods, my favorite group of organisms in the world, and essays 28 - 37 the hydrobioids, with topics of general evolutionary and systematic interest sprinkled throughout. Each essay opens with its date of publication, which is important to notice, because single subthemes can span multiple years, and my own thoughts have often evolved over time.We have deferred discussion of the Viviparids and the Ampullariids to Volume IV, which will be organized around ecological and biogeographical themes. This is partly due to space considerations, and partly because the most prominent elements of both families are invasive. It is probably unfair to tar higher taxa by the reputations of their most notorious species. For this I apologize.

These essays have been edited rather heavily from the form in which they were originally posted, in many cases, and re-ordered into subthemes. Essays 1 - 14 review topics in the Lymnaeidae, essays 16 - 21 the Ancylidae/Planorbidae, and essays 22 - 29 the Physidae, with topics of a more general nature sprinkled throughout.

Download or read book Essays on Ecology and Biogeography written by Robert T. Dillon and published by Freshwater Gastropods of North. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freswater snails are common and familiar inhabitants of rivers, lakes and streams throughout North America. In some environments they comprise the majority of the macroinvertabrate biomass, significantly influencing community composition, energy flow and nutrient cycling. Yet their biology remains almost as obscure to the scientific community as to the lay public. Collected in this volume are 30 essays on the ecology and biogeography of North American freshwater gastropods. Patterns of distribution are reviewed and analyzed at regional scales, with particular emphasis on mechanisms of dispersal. New invasions are reported, their progress monitored, and their consequences examined. The subjects of rarity and endemism, first introduced in Volume III, are explored at greater depth in Volume IV as well. The scholarly study of biogeography has, in recent years, become entangled with public policies regarding endangered species conservation and invasive species control. Here we review several striking cases where natural resource agencies have been misled by conservation biologists biased by research funding. We suggest that the correct relationship between science and public policy is analogous to playing baseball and playing the banjo -neither compatible nor incompatible, neither better nor worse, just entirely different. Volume I in this series analyzed the results of a scientific survey of the freshwater gastropod fauna of the Atlantic drainages from Georgia to the New York line. The essays collected here in Volume IV, together with those in Volume II (Pulmonates) and Volume III (Prosobranchs) will be essential companions to Volume I, as well as to additional volumes on the gastropod faunas of interior drainages forthcoming.
Download or read book Collected in Turn One and Other Essays written by Robert T Dillon Jr and published by Fwgna Project. This book was released on 2023-12-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the place of freshwater snails in modern culture, if any? Does their alleged rarity and undeniable strangeness elicit conservation concern in small circles of the environmentally conscious? Might even smaller circles of professionals in tropical medicine and health worry about their potential to host parasitic diseases? And aren't some freshwater snails invasive? Or maybe they're just cute pets? Collected in the present volume are 36 essays, originally published in the genre-defining artistic universe known as the FWGNA Blog, exploring freshwater gastropod biology in the modern mileau. Our focus is on the larger prosobranchs - the viviparids and the ampullariid "mystery snails" - as well as on the familiar pulmonate snails of the hobbyist aquarium and the lab bench. Reproductive allocation and the species concept, especially as applied to asexually-reproducing populations, emerge as primary themes, together with the omnipresent phenomenon of phenotypic plasticity. And along the way we'll check in with Gary, a pet mystery snail, who doesn't smell so good. The essays collected here will be an essential companion both to the Volume 1 results of the FWGNA surveys of Atlantic drainages published in 2019, and to the results of the Volume 5 Ohio drainage surveys published in 2023.

Download or read book Narrow Roads of Gene Land The Collected Papers of W D Hamilton written by W. D. Hamilton and published by OUP Oxford. This book was released on 2005-11-10 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: W. D. Hamilton (1936-2000) has been described by Richard Dawkins as 'a good candidate for the title of most distinguished Darwinian since Darwin'. His work on evolutionary biology continues to influence scientists working across a wide variety of disciplines, including evolution, population genetics, animal behaviour, genetics, anthropology, and ecology. This third and final volume of Narrow Roads of Gene Land contains Hamilton's key papers published between 1990 and 2000, a period in which he covered a great diversity of topics, often in collaboration with other scientists. Many of the papers in this volume continue his work on sex, and particularly its relation to parasitic disease, but other topics covered include the Gaia theory, the colours of autumn leaves, and the still-controversial hypothesis that the AIDS pandemic accidentally originated in a polio vaccination campaign in Africa. Each of the co-authored papers in this volume is preceded by an introduction written by one of Hamilton's co-authors, following the model of the previous two volumes in this series, which brings the reader closer to Hamilton's extraordinary personality and intellect, providing the intellectual and physical contexts within which each piece of research was developed. Also included are a chapter by Jeremy Leighton John on the Hamilton archive - 'Bill's last great work' - complete with irresistible pictures, and Alan Grafen's biographical memoir, which presents an overview of Bill's life and work. Together, this unique collection of papers with their biographical introductions provides a profound portrait of one of the twentieth century's most innovative scientists.

Book excerpt: Elements of Marine Ecology: An Introductory Course, Third Edition provides a concise discussion on the general field of marine ecology. The book is comprised of nine chapters that cover the structures and functions of marine ecosystems. The text first covers the oceans, including its extent and depths, currents, and biological features. Chapter 2 deals with marine planktons. Next, the book discusses the measuring and sampling techniques used at sea to obtain information of interest. The fourth chapter tackles the parameters of marine environment, while the fifth chapter deals with organic production in the sea. The text also covers the two extremities of the sea that are the seashore and the sea bottom. The last chapter discusses some concerns in sea fisheries. The book will be of great use to researchers and professionals whose work involves marine flora and fauna.
