Through the End of the Cretaceous in the Type Locality of the Hell Creek Formation in Montana and Adjacent Areas


Book Description

"The chapters represent a surge of field and laboratory research activity, illustrating the impacts of new and refined methods and tools. This volume explores geologic and biologic history preserved in the strata bounding the Cretaceous-Paleogene boundary"--Provided by publisher.




Dynamics of Extinction


Book Description

A comprehensive summary of current research and scientific thinking on the possible causes and mechanisms of large-scale periodic extinctions. Topics include the fossil record of extinctions, modern extinctions, theoretical modelling of extinction events, the periodicity of mass extinctions, modern extinctions, and more. Touches on many speculations and controversies. The articles, originally presented at a Northern Arizona University symposium at Flagstaff in 1983, have been revised and updated.




Macroevolution


Book Description

"Not only is a wealth of evidence presented to support the model of punctuated equilibria, but Stanley's stream of refreshing insights into classic topics of evolution, such as living fossils, mass extinctions and adaptive radiations add further weight to the validity of the general model".--GEOLOGICAL MAGAZINE. "Overall, Stanley offers an imaginative treatment of almost every issue in macroevolution".--AMERICAN SCIENTIST. 192 illustrations.




Dynamics of Dinosaurs and Other Extinct Giants


Book Description

How did the larger dinosaurs run? How and why did they fight? The author applies laws of physics, mechanical engineering and aerodynamics to answer these and other questions.




Biodiversity Dynamics


Book Description

How will patterns of human interaction with the earth's eco-system impact on biodiversity loss over the long term--not in the next ten or even fifty years, but on the vast temporal scale be dealt with by earth scientists? This volume brings together data from population biology, community ecology, comparative biology, and paleontology to answer this question.




In the Light of Evolution


Book Description

Biodiversity-the genetic variety of life-is an exuberant product of the evolutionary past, a vast human-supportive resource (aesthetic, intellectual, and material) of the present, and a rich legacy to cherish and preserve for the future. Two urgent challenges, and opportunities, for 21st-century science are to gain deeper insights into the evolutionary processes that foster biotic diversity, and to translate that understanding into workable solutions for the regional and global crises that biodiversity currently faces. A grasp of evolutionary principles and processes is important in other societal arenas as well, such as education, medicine, sociology, and other applied fields including agriculture, pharmacology, and biotechnology. The ramifications of evolutionary thought also extend into learned realms traditionally reserved for philosophy and religion. The central goal of the In the Light of Evolution (ILE) series is to promote the evolutionary sciences through state-of-the-art colloquia-in the series of Arthur M. Sackler colloquia sponsored by the National Academy of Sciences-and their published proceedings. Each installment explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. This tenth and final edition of the In the Light of Evolution series focuses on recent developments in phylogeographic research and their relevance to past accomplishments and future research directions.




Metapopulation Dynamics: Empirical and Theoretical Investigations


Book Description

Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. After briefly discussing the history of metapopulation ideas and the major conceptual links, the book covers types of studies that have been conducted on single-species and multispecies metapopulations. Then, it examines the relationships between metapopulation dynamics, the equilibrium theory of island biogeography, and the dynamics of populations living in patchy environments. It further tackles practical issues and the links between metapopulation dynamics and landscape ecology, and between metapopulation dynamics and conservation biology. Chapters 4 and 5 present structured models describing changes in the number of individuals within patches and an empirical evaluation of local extinction in metapopulation studies. The subsequent chapters discuss several aspects of metapopulation, including dispersal and connectivity, colonization, conspecific attraction, extinction and isolation, and forest fragmentation. The latter chapters describe the concept of habitat fragmentation, the diversity and competition in metapopulations, the community collapse, and the effects of metapopulation studies in predator-prey systems.

Extinction


Book Description

Some thousands of years ago, the world was home to an immense variety of large mammals. From wooly mammoths and saber-toothed tigers to giant ground sloths and armadillos the size of automobiles, these spectacular creatures roamed freely. Then human beings arrived. Devouring their way down the food chain as they spread across the planet, they began a process of voracious extinction that has continued to the present. Headlines today are made by the existential threat confronting remaining large animals such as rhinos and pandas. But the devastation summoned by humans extends to humbler realms of creatures including beetles, bats and butterflies. Researchers generally agree that the current extinction rate is nothing short of catastrophic. Currently the earth is losing about a hundred species every day. This relentless extinction, Ashley Dawson contends in a primer that combines vast scope with elegant precision, is the product of a global attack on the commons, the great trove of air, water, plants and creatures, as well as collectively created cultural forms such as language, that have been regarded traditionally as the inheritance of humanity as a whole. This attack has its genesis in the need for capital to expand relentlessly into all spheres of life. Extinction, Dawson argues, cannot be understood in isolation from a critique of our economic system. To achieve this we need to transgress the boundaries between science, environmentalism and radical politics. Extinction: A Radical History performs this task with both brio and brilliance.
