Book Description
The fossil record offers a surprising image: that of evolutionary radiations characterized by intense increases in cash or by the sudden diversification of a single species group, while others stagnate or die out. In a modern world, science carries an often pessimistic message, surrounded by studies of global warming and its effects, extinction crisis, emerging diseases and invasive species. This book fuels frequent "optimism" of the sudden increase in biodiversity by exploring this natural phenomenon. Events of Increased Biodiversity: Evolutionary Radiations in the Fossil Record explores this natural phenomenon of adaptive radiation including its effect on the increase in biodiversity events, their contribution to the changes and limitations in the fossil record, and examines the links between ecology and paleontology's study of radiation. - Details examples of evolutionary radiations - Explicitly addresses the effect of adaptation driven by ecological opportunity - Examines the link between ecology and paleontology's study of adaptive radiation

Book Description
Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. This is the first book devoted specifically to establishing the global patterns of differentiation of Ordovician biotas through time and space. It provides extensive genus- and species-level diversity data for the many Ordovician fossil groups and presents an evaluation of how each group diversified, with assessments of patterns of change, and rates of origination and extinction.

Book Description
The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

Book Description
The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

Speciation and Patterns of Diversity

Book Description
The diversity of species of plants and animals is the net result of the origin of new species by the splitting of existing lineages (speciation) and the loss of species through extinction. Why there are more species in some groups of organisms, in some places or at some times depends on the balance of these processes. This book explores the interaction between mechanisms and rates of speciation and these patterns of biological diversity, and is unusual in that it brings together the viewpoints of ecologists interested in the processes that generate patterns of diversity and evolutionary biologists who focus on mechanisms of speciation. It is intended to stimulate dialogue between these groups and so promote a more complete understanding of biological diversity.

Book Description
Risk and Social Theory in Environmental Managementmarks a timely contribution, given that environmental management is no longer just about protecting pristine ecosystems and endangered species from anthropogenic harm; it is about calculating and managing the risks to human communities of rapid environmental and technological change. First, the book provides a solid foundation of the social theory underpinning the nature of risk, then presents a rethinking of key concepts and methods in order to take more seriously the biophysical embeddedness of human society. Second, it presents a rich set of case studies from Australia and around the world, drawing on the latest applied research conducted by leading research institutions. In so doing, the book identifies the tensions that arise from decision making over risk and uncertainty in a contested policy environment, and provides crucial insights for addressing on-the-ground problems in an integrated way. * First volume to address environmental risk from a social science perspective * Latest theoretical developments * In depth case studies of contemporary issues (e.g. climate change, water shortages)

Book Description
Dominance and Aggression in Humans and Other Animals: The Great Game of Life examines human nature and the influence of evolution, genetics, chemistry, nurture, and the sociopolitical environment as a way of understanding how and why humans behave in aggressive and dominant ways. The book walks us through aggression in other social species, compares and contrasts human behavior to other animals, and then explores specific human behaviors like bullying, abuse, territoriality murder, and war. The book examines both individual and group aggression in different environments including work, school, and the home. It explores common stressors triggering aggressive behaviors, and how individual personalities can be vulnerable to, or resistant to, these stressors. The book closes with an exploration of the cumulative impact of human aggression and dominance on the natural world. - Reviews the influence of evolution, genetics, biochemistry, and nurture on aggression - Explores aggression in multiple species, including insects, fish, reptiles, birds, and mammals - Compares human and animal aggressive and dominant behavior - Examines bullying, abuse, territoriality, murder, and war - Includes nonaggressive behavior in displays of respect and tolerance - Highlights aggression triggers from drugs to stress - Discusses individual and group behavior, including organizations and nations - Probes dominance and aggression in religion and politics - Translates the impact of human behavior over time on the natural world
