Book Synopsis The Ptarmigan's Dilemma by : John Theberge
Download or read book The Ptarmigan's Dilemma written by John Theberge and published by McClelland & Stewart. This book was released on 2011-04-05 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2010 Lane Anderson Award Drawing on breakthrough research in evolution, genetics, and on their extensive work in the field and lab, wildlife biologists John and Mary Theberge explain for non-scientists the real facts of life. Birds that suddenly grow gall bladders, when their species has none. Moose with antlers so big they encumber their movement through the forest. Butterflies that risk extinction by overwintering en masse. These are just a few stories the Theberges tell in their examination of what the mechanisms of evolution are and how they work. With examples from the very latest discoveries in genetics and ones they have made in their own field work, The Ptarmigan's Dilemma is a ground-breaking explanation of evolution for non-scientists. By marrying the separate sciences of ecology and genetics, the Theberges paint a picture far richer than either discipline can alone of how, for almost 4 billion years, life on Earth has evolved into the rich diversity that's under threat today. Along the way, they explain just what "the survival of the fittest" really means, how dramatic evolutionary changes can take place in just one generation, and how our too-little knowledge of or interest in how life on Earth organizes and supports itself is rapidly making us a danger to ourselves.

Book Synopsis Annotated Bibliography of Colorado Vertebrate Zoology, 1776-1995 by : Richard G. Beidleman
Download or read book Annotated Bibliography of Colorado Vertebrate Zoology, 1776-1995 written by Richard G. Beidleman and published by . This book was released on 2000 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation catalogues the writings on the diverse vertebrate species within Colorado's boundaries beginning with the Escalante Expedition, which skirted the western slope a century before Colorado's statehood. Because of its geographical location-between East and West, North and Southwest, its altitudinal range of more than 11,000 feet, and its consequent variety of ecosystems from desert shrub to alpine tundra, Colorado ranks high among the fifty states for its variety of vertebrates. With such an abundance of these vertebrates, biologists and observant laypersons have had much to write about. This comprehensive bibliography is divided into major sections: General Natural History, Fishes, Amphibians, Reptiles, Birds and Mammals. Each taxonomic group has a general section, followed by listings at taxon levels down to alphabetically-arranged species. The bibliography is especially complete with respect to periodical literature through 1995. Colorado Vertebrate Zoology cites resources for studying both well-researched vertebrates and those needing more study.

Book Synopsis Environmental Dilemmas by : Robert Mugerauer
Download or read book Environmental Dilemmas written by Robert Mugerauer and published by Toposophia: Thinking Place/Making Space. This book was released on 2008 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because many people and ecosystems share--or constitute--any given place, they all have a stake in the outcome of what any of us do in regard to environmental problems. It is not surprising that issues are hotly contested given the many divergent interests, needs, and preferences of a community's members, much less those of people "downstream" who are affected by the consequences of our actions or of "outside" parties who play a part, including those who would speak on behalf of the ecosystems. Thus, we not only must make careful individual decisions concerning the environment, but need to improve the way we operate socially, especially given the roles and responsibilities we have as environmental professionals, private-sector developers, public policy-makers and staff, or engaged citizens. To aid in resolving our environmental dilemmas, Mugerauer and Manzo focus on the decision making process. Their goal is to help readers become more aware of the worldviews, beliefs, and values that enter into the decisions they make and to better resolve differences with others. To guide readers in thinking about their own positions and how to approach ethical decisions, Mugerauer and Manzo employ a number of exercises and cases to investigate the choices and issues that different stakeholders face (for example, concerning sustainability). Additionally, the book presents alternatives in terms of formalized ethical principles, the major ethical theories, and professional codes of ethics.
