Citizen Science - - Bog - Cornell University Press - Plusbog.dk

Citizen science enlists members of the public to make and record useful observations, such as counting birds in their backyards, watching for the first budding leaf in spring, or measuring local snowfall. The large numbers of volunteers who participate in projects such as Project FeederWatch or Project BudBurst collect valuable research data, which, when pooled together, create an enormous body of scientific data on a vast geographic scale. In return, such projects aim to increase participants’ connections to science, place, and nature, while supporting science literacy and environmental stewardship. In Citizen Science , experts from a variety of disciplines—including scientists and education specialists working at the Cornell Lab of Ornithology, where many large citizen science programs use birds as proxies for biodiversity—share their experiences of creating and implementing successful citizen science projects, primarily those that use massive data sets gathered by citizen scientists to better understand the impact of environmental change. This first and foundational book for this developing field of inquiry addresses basic aspects of how to conduct citizen science projects, including goal-setting, program design, and evaluation, as well as the nuances of creating a robust digital infrastructure and recruiting a large participant base through communications and marketing. An overview of the types of research approaches and techniques demonstrates how to make use of large data sets arising from citizen science projects. A final section focuses on citizen science’s impacts and its broad connections to understanding the human dimensions and educational aspects of participation. Citizen Science teaches teams of program developers and researchers how to cross the bridge from success at public engagement to using citizen science data to understand patterns and trends or to test hypotheses about how ecological processes respond to change at large geographic scales. Intended as a resource for a broad audience of experts and practitioners in natural sciences, information science, and social sciences, this book can be used to better understand how to improve existing programs, develop new ones, and make better use of the data resources that have accumulated from citizen science efforts. Its focus on harnessing the impact of "crowdsourcing" for scientific and educational endeavors is applicable to a wide range of fields, especially those that touch on the importance of massive collaboration aimed at understanding and conserving what we can of the natural world.

Vultures of the World - Keith L. Bildstein - Bog - Cornell University Press - Plusbog.dk

In Vultures of the World, Keith L. Bildstein provides an engaging look at vultures and condors, seeking to help us understand these widely recognized but underappreciated birds. Bildstein's latest work is an inspirational and long overdue blend of all things vulture. Based on decades of personal experience, dozens of case studies, and numerous up-to-date examples of cutting-edge science, this book introduces readers to the essential nature of vultures and condors. Not only do these most proficient of all vertebrate scavengers clean up natural and man-made organic waste but they also recycle ecologically essential elements back into both wild and human landscapes, allowing our ecosystems to function successfully across generations of organisms. With distributions ranging over more than three-quarters of all land on five continents, the world's twenty-three species of scavenging birds of prey offer an outstanding example of biological diversity writ large. Included in the world's species fold are its most abundant large raptors—several of its longest lived birds and the most massive of all soaring birds. With a fossil record dating back more than fifty million years, vultures and condors possess numerous adaptions that characteristically serve them well but at times also make them particularly vulnerable to human actions. Vultures of the World is a truly global treatment of vultures, offering a roadmap of how best to protect these birds and their important ecology.

The Beaver - Dietland Muller Schwarze - Bog - Cornell University Press - Plusbog.dk

The Beaver - Dietland Muller Schwarze - Bog - Cornell University Press - Plusbog.dk

Beavers can and do dramatically change the landscape. The beaver is a keystone species—their skills as foresters and engineers create and maintain ponds and wetlands that increase biodiversity, purify water, and prevent large-scale flooding. Biologists have long studied their daily and seasonal routines, family structures, and dispersal patterns. As human development encroaches into formerly wild areas, property owners and government authorities need new, nonlethal strategies for dealing with so-called nuisance beavers. At the same time, the complex behavior of beavers intrigues visitors at parks and other wildlife viewing sites because it is relatively easy to observe. In an up-to-date, exhaustively illustrated, and comprehensive book on beaver biology and management, Dietland Müller-Schwarze gathers a wealth of scientific knowledge about both the North American and Eurasian beaver species. The Beaver is designed to satisfy the curiosity and answer the questions of anyone with an interest in these animals, from students who enjoy watching beaver ponds at nature centers to homeowners who hope to protect their landscaping. Photographs taken by the authors document every aspect of beaver behavior and biology, the variety of their constructions, and the habitats that depend on their presence. Beaver facts: •Just as individual beavers shape their immediate surroundings, so did the distribution of beavers across North America influence the paths of English and French explorers and traders. As a result of the fur trade, beavers were wiped out across large areas of the United States. Reintroduction efforts led to the widespread establishment of these resilient animals, and now they are found throughout North America, Europe, and parts of the southern hemisphere. •Beaver meadows provided early settlers with level, fertile pastures and hayfields. •Based on the fossil record, the smallest extinct beaver species were the size of a muskrat, and the largest may have reached the size of a black bear (five to six times as large as today''s North American beavers). Beaver-gnawed wood has been found alongside the skeleton of a mastodon. •Some beavers remain in the home lodge for an extra year to assist their parents in raising younger siblings. They feed, groom, and guard the newborn kits. •In 1600, beaver ponds covered eleven percent of the upper Mississippi and Missouri Rivers'' watershed above Thebes, Illinois. Restoring only 3 percent of the original wetlands might suffice to prevent catastrophic floods such as those in the early 1990s.
