Population biology.
Monitoring Plant and Animal Populations offers an overviewof population monitoring issues that is accessible to the typicalfield biologist and land managers with a modest statisticalbackground. The text includes concrete guidelines for ecologists tofollow to design a statistically defensible monitoringprogram. User-friendly, practical guide, written in a highly readableformat. The authors provide an interdisciplinary scope to address thecurrent, widespread interest in monitoring in many environmentalfields, including pure and applied ecology, conservation biology,and wildlife management. Emphasizes the role of monitoring in adaptive management. Defines important terminology and contrasts monitoring withother data-collection activities. Covers the applicable principlesof sampling and shows how to design a monitoring project. Provides a step-by-step overview of the monitoring process,illustrated by flow charts and references. The authors also offerguidelines for analyzing and interpreting monitoring data. Illustrates the foundation of management objectives anddescribes their components, types, and development. Describes common field techniques for measuring importantattributes of animal and plant populations. Reviews different methods for recording monitoring data in thefield, managing the data, and communicating data to policymakers.
Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.
One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.
In a time of uncertainty about our environmental future—an eye-opening global tour of some of the most wounded places on earth, and stories of how a passionate group of eco-restorers is leading the way to their revitalization. Award-winning science journalist Judith D. Schwartz takes us first to China’s Loess Plateau, where a landmark project has successfully restored a blighted region the size of Belgium, lifting millions of people out of poverty. She journeys on to Norway, where a young indigenous reindeer herder challenges the most powerful orthodoxies of conservation—and his own government. And in the Middle East, she follows the visionary work of an ambitious young American as he attempts to re-engineer the desert ecosystem, using plants as his most sophisticated technology. Schwartz explores regenerative solutions across a range of landscapes: deserts, grasslands, tropics, tundra, Mediterranean. She also highlights various human landscapes, the legacy of colonialism and industrial agriculture, and the endurance of indigenous knowledge. The Reindeer Chronicles demonstrates how solutions to seemingly intractable problems can come from the unlikeliest of places, and how the restoration of local water, carbon, nutrient, and energy cycles can play a dramatic role in stabilizing the global climate. Ultimately, it reveals how much is in our hands if we can find a way to work together and follow nature’s lead.
Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.

“Tallamy lays out all you need to know to participate in one of the great conservation projects of our time. Read it and get started!” —Elizabeth Kolbert, Pulitzer Prize-winning author of The Sixth Extinction Douglas W. Tallamy’s first book, Bringing Nature Home, awakened thousands of readers to an urgent situation: wildlife populations are in decline because the native plants they depend on are fast disappearing. His solution? Plant more natives. In this new book, Tallamy takes the next step and outlines his vision for a grassroots approach to conservation. Nature’s Best Hope shows how homeowners everywhere can turn their yards into conservation corridors that provide wildlife habitats. Because this approach relies on the initiatives of private individuals, it is immune from the whims of government policy. Even more important, it’s practical, effective, and easy—you will walk away with specific suggestions you can incorporate into your own yard. If you’re concerned about doing something good for the environment, Nature’s Best Hope is the blueprint you need. By acting now, you can help preserve our precious wildlife—and the planet—for future generations.
