Book Description
Biogeography, first published in 1983, is one of the most comprehensive text and general reference books in the natural sciences. The Fifth Edition builds on the strengths of previous editions to provide an insightful and integrative explanation of how geographic variation across terrestrial and marine environments has influenced the fundamental processes of immigration, extinction, and evolution to shape species distributions and nearly all patterns of biological diversity. It is an empirically and conceptually rich text that illustrates general patterns and processes using examples from a broad diversity of life forms, time periods and aquatic and terrestrial ecosystems. Its fundamental assertion is that patterns in biological diversity make little sense unless viewed within an explicit geographic context. Starting from principal patterns and fundamental principles, and assuming only a rudimentary knowledge of biology, geography, and Earth history, the text explains the relationships between geographic variation in biological diversity and the geological, ecological, and evolutionary processes that have produced them. The use of color illustrations, evaluated and optimized for colorblind readers, has transformed our abilities to illustrate key concepts and empirical patterns in the geography of nature. By providing a description of the historical development of biogeography, evolution and ecology, along with a comprehensive account of the principal patterns, fundamental principles and recent advances in each of these fields of science, our ultimate vision is for Biogeography to serve as the centerpiece of a one- or two-semester core course in biological diversity.

Book Description
The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.
Is Random Time Diversification a Substitute for Static Space Diversification?

ISBN: 1420045512
Category : Science
Languages : en
Pages : 242
Book Description
Biogeography represents one of the most complex and challenging aspects of macroevolutionary research, requiring input from both the earth and life sciences. Palaeogeographic reconstruction is frequently carried out by researchers with backgrounds in geology and palaeontology, who are less likely to be familiar with the latest biogeographic techniques: conversely, biogeographic methods are often devised by neontologists who may be less familiar with the fossil record, stratigraphy, and palaeogeography. Palaeogeography and Palaeobiogeography: Biodiversity in Space and Time bridges the gap between these two communities of researchers, who work on the same issues but typically use different types of data. The book covers a range of topics, and reflects some of the major overall questions in the field such as: Which approaches are best suited to reconstructing biogeographic histories under a range of circumstances? How do we maximize the use of organismal and earth sciences data to improve our understanding of events in earth history? How well do analytical techniques devised for researching the biogeography of extant organisms perform in the fossil record? Can alternative biodiversity metrics, particularly those based on morphological measurements, enhance our understanding of biogeographic patterns and processes? This book approaches palaeobiogeography with coverage of technological applications and detailed case studies. It spans a wide selection of overlapping and integrative disciplines, including evolutionary theory, vicariance biogeography, extinctions, and the philosophical aspects of palaeogeography. It also highlights new technological innovations and applications for research. Presenting a unique discussion of both palaeogeography and palaeobiogeography in one volume, this book focuses both historically and philosophically on the interface between geology, climate, and organismal distribution.
Portfolio Diversification

Pages : 276
Book Description
Portfolio Diversification provides an update on the practice of combining several risky investments in a portfolio with the goal of reducing the portfolio's overall risk. In this book, readers will find a comprehensive introduction and analysis of various dimensions of portfolio diversification (assets, maturities, industries, countries, etc.), along with time diversification strategies (long term vs. short term diversification) and diversification using other risk measures than variance. Several tools to quantify and implement optimal diversification are discussed and illustrated. Focuses on portfolio diversification across all its dimensions Includes recent empirical material that was created and developed specifically for this book Provides several tools to quantify and implement optimal diversification

Languages : en
Pages : 816
Book Description
This book provides a comprehensive overview of the patterns of biodiversity in various neotropical ecosystems, as well as a discussion on their historical biogeographies and underlying diversification processes. All chapters were written by prominent researchers in the fields of tropical biology, molecular ecology, climatology, paleoecology, and geography, producing an outstanding collection of essays, synthetic analyses, and novel investigations that describe and improve our understanding of the biodiversity of this unique region. With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannahs, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic, which will fascinate both scientists and general readers alike.
