Showing results for "Understanding Understanding" in Environment

Understanding Nature is a new kind of ecology textbook: a straightforward resource that teaches natural history and ecological content, and a way to instruct students that will nurture both Earth and self. While meeting the textbook guidelines set forth by the Ecological Society of America, Understanding Nature has a unique ecotherapy theme, using a historical framework to teach ecological theory to undergraduates.

In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses.

In these 24 lectures, The Great Courses teams up with the Smithsonian’s National Zoo and Conservation Biology Institute, to take you behind the scenes of the animal world. Dr. Moore has crafted a wonderful introduction to zoology that brings you up close and personal with a breathtaking variety of animal species through the eyes of a trained zoologist.

What is animal welfare? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as "health and animals having what they want", a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare.
