Accessible and beautifully illustrated, this book collates global scientific research on the evolution, ecology and behaviour of barn owls and their relatives into a single volume. For researchers in ornithology, animal behaviour, ecology, conservation biology and evolutionary biology, it will also appeal to amateurs interested in barn owls.

Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. Mitchell Thomashow, a preeminent educator, shows how environmental studies can be taught from different perspective, one that is deeply informed by personal reflection. Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. What do I know about the place where I live? Where do things come from? How do I connect to the earth? What is my purpose as a human being? These are the questions that Thomashow identifies as being at the heart of environmental education. Developing a profound sense of oneself in relationship to natural and social ecosystems is necessary grounding for the difficult work of environmental advocacy. In this book he provides a clear and accessible guide to the learning experiences that accompany the construction of an "ecological identity": using the direct experience of nature as a framework for personal decisions, professional choices, political action, and spiritual inquiry. Ecological Identity covers the different types of environmental thought and activism (using John Muir, Henry David Thoreau, and Rachel Carson as environmental archetypes, but branching out into ecofeminism and bioregionalism), issues of personal property and consumption, political identity and citizenship, and integrating ecological identity work into environmental studies programs. Each chapter has accompanying learning activities such as the Sense of Place Map, a Community Network Map, and the Political Genogram, most of which can be carried out on an individual basis. Although people from diverse backgrounds become environmental activists and enroll in environmental studies programs, they are rarely encouraged to examine their own history, motivations, and aspirations. Thomashow's approach is to reveal the depth of personal experience that underlies contemporary environmentalism and to explore, interpret, and nurture the learning spaces made possible when people are moved to contemplate their experience of nature.

Reissued on the tenth anniversary of its publication, this classic work on our environmental crisis features a new introduction by the author, reviewing both the progress and ground lost in the fight to save the earth. This impassioned plea for radical and life-renewing change is today still considered a groundbreaking work in environmental studies. McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever. McKibben writes of our earth's environmental cataclysm, addressing such core issues as the greenhouse effect, acid rain, and the depletion of the ozone layer. His new introduction addresses some of the latest environmental issues that have risen during the 1990s. The book also includes an invaluable new appendix of facts and figures that surveys the progress of the environmental movement. More than simply a handbook for survival or a doomsday catalog of scientific prediction, this classic, soulful lament on Nature is required reading for nature enthusiasts, activists, and concerned citizens alike.

The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
