Available in PDF, EPUB and Kindle. Book excerpt: This updated and expanded A New Island Biogeography of the Sea of Cort'es, first published nearly 20 years ago, integrates new and broader studies encompassing more taxa and more complete island coverage. The present synthesis provides a basis for further research and exploration in upcoming years of the biologically fascinating Sea of Cort'es region. The Gulf region is increasingly being exploited, for its natural resources by way of marine fisheries, and for its stunning natural beauty by way of a burgeoning tourism industry. Further, the region's human population is increasing apace. It is appropriate, therefore, that this volume discusses these evolving circumstances, and the efforts of the Mexican government to regulate and manage them. The new Biogeography includes a section on the conservation issues in the Sea of Cort'es, past accomplishments and conservation needs as yet outstanding. This book should be of strong interest to conservation biologists, ecologists, and evolutionary biologists more generally.

Book excerpt: The recent progress in analytical methods, aided by bringing in a wide range of other disciplines, opens up the study to a broader field, which means that biogeography now goes far beyond a simple description of the distribution of living species on Earth. Originating with Alexander von Humboldt, biogeography is a discipline in which ecologists and evolutionists aim to understand the way that living species are organized in connection with their environments. Today, as we face major challenges such as global warming, massive species extinction and devastating pandemics, biogeography offers hypotheses and explanations that may help to provide solutions. This book presents as wide an overview as possible of the different fields that biogeography interacts with. Sixteen authors from all over the world offer different approaches based on their specific areas of knowledge and experience; thus, we intend to illustrate the vast number of diverse aspects covered by biogeography.

This book was released on 1965 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Islands, with their simplified ecosystems and isolation from other populations in both space & time, provide natural settings for the study of numerous disciplines in relation to evolution. The Queen Charlotte Islands are some of the more isolated islands on the north-west coast of North America and are therefore of special interest in the study of the biotic evolution of this region. The purpose of this paper is to report on an analysis of the evolution of the native land mammals of these islands. An important aspect is to determine how much of the endemism present on the islands is accounted for by reason of its being a relict population or how much is a contribution of the insularity of the environment. The paper begins with a review of the Islands' setting and an assessment of the possibility of glacial refugia being present on the island. The Islands' physiography, vegetation, endemic species, the impoverished nature of the fauna encountered, and the probability of species survival in a refugium during the last glaciation are reviewed. The second section examines eight species of native mammals in an attempt to reconstruct their past history in a Queen Charlotte setting. The research is based on field studies conducted in 1960 & 1961 and examination of specimens collected & specimens in museums. Sources of variation, rates of evolution, and factors responsible for species appearance or disappearance are discussed. The final chapter reviews the evolution of mammals on other islands to show any trends which may be present in insular mammals.

Available in PDF, EPUB and Kindle. Book excerpt: Biological homogenization is the dominant process shaping the future global biosphere. As global transportation becomes faster and more frequent, it is inevitable that biotic intermixing will increase. Unique local biotas will become extinct only to be replaced by already widespread biotas that can tolerate human activities. This process is affecting all aspects of our world: language, economies, and ecosystems alike. The ultimate outcome is the loss of uniqueness and the growth of uniformity. In this way, fast food restaurants exist in Moscow and Java Sparrows breed on Hawaii. Biological homogenization qualifies as a global environmental catastrophe. The Earth has never witnessed such a broad and complete reorganization of species distributions.
