Download or read book Essays on the Pulmonates 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: Volume 1 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 30 years over which the FWGNA Project has developed, 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 1. Here in Volume 2 we collect 29 essays on the evolutionary biology and systematics of the freshwater pulmonate gastropods, published online between 2004 and 2015. 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. Each essay opens with its date of publication, which is important to notice, because single themes can span multiple years, and my own thoughts have often evolved over time.

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.

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.
