Disturbance in the garden: toward a new portrayal of wildfire in science and natural history films: Author: Roberts, Jeremy Russell; Date: 2009-05-15; Program: Science and Natural History Filmmaking; Abstract: Science has proven that wildfire has a positive rejuvenating effect on many ecosystems, creating new habitat and bolstering global biodiversity. Despite growing scientific understanding of wildfire over the past 100 years, science and natural history films repeatedly position wildfire merely to achieve dramatic effect. These films typically ignore the available science and in many cases contradict scientific truth outright for the sake of the dramatic narrative.

Riparian vegetation and forest structure of two unregulated tributaries, compared to the regulated Snake River, Grand Teton NP, WY: Author: Foy, Elizabeth Christina; Date: 2008-12-15; Program: Biological Sciences; Abstract: The dynamic nature of rivers shapes riparian plant communities, and changes to the flow regime can have profound effects on these diverse ecosystems. To examine how riparian plant communities of the dam-regulated Snake River in Grand Teton National Park, WY respond to hydro-geomorphological factors, I studied the vegetation of two unregulated tributaries, Pacific Creek and Buffalo Fork, in relation to the main river. I considered three perspectives in this analysis. In chapter 2, I examined hydro-geomorphological processes shaping riparian vegetation in naturally flowing systems, by evaluating...; Download File | View full details
