This book was released on 2010 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the impact of road crossings on benthic macroinvertebrate communities in a wadeable Ozark river. I collected macroinvertebrates during winter and summer from four riffle locations (upstream, at crossing, downstream, and farther downstream) at each of five sites in the upper Current River (mean discharge 12 m3 s-1). Sixteen environmental variables were measured at each location to characterize sites. Using digital photographs from trail cameras, traffic frequencies were calculated and largely consisted of hikers and horses. Based on counts of 68,353 individuals from 111 macroinvertebrate taxa, I calculated four metrics (taxa richness, Shannon's index, EPT, biotic index) combined into the Stream Condition Index and assessed effects of stream crossings with a two-way nested ANOVA for each season. All metrics showed strong differences among sites but inconsistent effects among locations. Multivariate analyses (NMDS and a nested ANOSIM) also revealed strong differences in community composition among sites, as well as among locations. Taken together, the results indicate crossing disturbances during summer and winter 2009 were either too infrequent or small in intensity to impair benthic macroinvertebrate communities.

This book was released on 2023-01-17 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."

Book excerpt: This collection of papers analyzes the Pioneer Forest, a privately owned 150,000-acre working forest in the Missouri Ozarks, on which the science and art of forest management has been practiced for more than 50 years. The papers discuss how this half century of management has contributed to forest restoration and sustainability on the forest itself and, through its example undergirded by a remarkable body of research, throughout the Ozark region and beyond.
