Environmental education has often blurred the distinction between ecological science and environmental advocacy. Growing public awareness of environmental problems and desire for action may be contributing to this blurring. There is a need to clarify the distinction between the role of ecological science and the role of social and political values for the environment within environmental education. This book addresses this need by examining the changing perspectives of ecology in education and the changing perspectives of education in environmental education. Guidelines are provided for assessing the science and education perspectives within environmental education, along with suggested frameworks for development of programs and resources that integrate current science, education and action. This book will be of interest to environmental educators, ecologists interested in environmental education, and curriculum and resource developers.

It is almost dogma that the boreal forest in North America is a fire-dependent forest, yet ecologists often do not consider in any technical detail how forest fires produce effects on individual plants and on plant populations. Consequently, the causal connection between the behaviour of fire and its ecological consequences is poorly understood. This book sets out to correct this deficiency by assembling the relevant studies of fire intensity, rate of spread, fuel consumption, fire frequency and fire weather in the North American boreal forest. The central thesis is that the North American boreal forest has at least four wildfire characteristics that are important in understanding the dynamics of its plant populations: the large size of the burns with respect to dispersal distances, the short recurrence time of fire with respect to tree lifespans, the high mortality of plants due to the predominance of crown fires, and a good germination surface due to the large area of the forest

Biogeoscience is a rapidly growing interdisciplinary field that aims to bring together biological and geophysical processes. This book builds an enhanced understanding of ecosystems by focusing on the integrative connections between ecological processes and the geosphere, hydrosphere and atmosphere. Each chapter provides studies by researchers who have contributed to the biogeoscience synthesis, presenting the latest research on the relationships between ecological processes, such as conservation laws and heat and transport processes, and geophysical processes, such as hillslope, fluvial and aeolian geomorphology, and hydrology. Highlighting the value of biogeoscience as an approach to understand ecosystems, this is an ideal resource for researchers and students in both ecology and the physical sciences.

Who were the Gestapo officers? Were they merely banal paper shufflers, or were they recognizably evil? Were they motivated by an eliminationist anti-Semitism? Did the average German know about the mas

Patapsco Valley State Park is nestled in four Maryland counties--Carroll, Baltimore, Howard, and Anne Arundel. From its humble beginnings in 1907 as a 43-acre forest reserve to its expansion to over 1
