Book excerpt: It follows naturally from the widely accepted Darwinian dictum that failures of populations or of species to adapt and to evolve under changing environments will result in their extinction. Population geneti cists have proclaimed a centerstage role in developing conservation biology theory and applications. However, we must critically reexamine what we know and how we can make rational contributions. We ask: Is genetic variation really important for the persistence of species? Has any species become extinct because it ran out of genetic variation or because of inbreeding depression? Are demographic and environmental stochas ticity by far more important for the fate of a population or species than genetic stochasticity (genetic drift and inbreeding)? Is there more to genetics than being a tool for assessing reproductive units and migration rates? Does conventional wisdom on inbreeding and "magic numbers" or rules of thumb on critical effective population sizes (MVP estimators) reflect any useful guidelines in conservation biology? What messages or guidelines from genetics can we reliably provide to those that work with conservation in practice? Is empirical work on numerous threatened habitats and taxa gathering population genetic information that we can use to test these guidelines? These and other questions were raised in the invitation to a symposium on conservation genetics held in May 1993 in pleasant surroundings at an old manor house in southern Jutland, Denmark.

Download or read book Modern Ecology written by G. Esser and published by Elsevier. This book was released on 2016-07-29 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on many case studies in the broad area of ecological studies and is derived from numerous sources originating from several countries. The book begins with discussions on morphology, stand structure, competition, mass and water balance at the stand level of vegetation as well as mineral cycles. A section deals with disturbances and management of agricultural as well as semi-natural systems. With the input of several authors, zoologists, botanists and geographers, detail is given to the eutrophication and pollution in terrestrial ecosystems. Included as well are discussions on the carbon cycle as it relates to current climate change and modern methods of remote sensing and geographical modelling. The book concludes with a chapter on urban and landscape ecology. The main feature of this book is that it includes most methods and tasks of modern ecology using case studies and incorporating all levels of integration from single plants and animals to populations and ecosystems.
