Effects of Alternatives to Clearcutting on Invertebrate and Organic Detritus Transport from Headwaters in Southeastern Alaska
We examined the transport of invertebrates and coarse organic detritus from headwater streams draining timber harvest units in a selective timber harvesting study, alternatives to clearcutting (ATC) in southeastern Alaska. Transport in 17 small streams (mean measured discharge range: 1.2 to 14.6 L/s) was sampled with 250- m-mesh drift nets in spring, summer, and fall near Hanus Bay at an ATC installation on Catherine and Baranof Islands. Samples were taken before (1996) and after (1999, 2000) nine timber harvesting treatments were applied. Invertebrate and organic detritus drift densities and community composition were used to assess treatment effects. A comparison of drift densities before ...
The Tragedy of the Commodity
Winner of the 2017 Paul Sweezy Marxist Sociology Book Award from the American Sociological Association Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In ...
Hornyheads, Madtoms, and Darters
A collection of essays on nature, naturalists, and the natural history of fishes in central Appalachia. A nature lover’s paradise, central Appalachia supports a diversity of life in an extensive network of waterways and is home to a dazzling array of fish species. This book focuses not only on the fishes of central Appalachia but also on the fascinating things these fishes do in their natural habitats. An ecological dance unfolds from a species and population perspective, although the influence of the community and the ecosystem also figures in the text. Stuart A. Welsh’s essays link central Appalachian fishes with the complexities of competition and predation, species conservation, para...
Compatible Forest Management
Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
Salmon
Salmon: A Scientific Memoir investigates a narrative that is important to the identity of the Pacific Northwest Coast—the salmon as an iconic species. Traditionally it's been a narrative that is overwhelmingly about conflict. But is that always necessarily the case? The story follows John Steinbeck's advice: the best way to achieve reality is to combine narrative with scientific data. By following ecologists, archaeologists and fisheries biologists studying salmon, humans and their shared habitat, the reader learns about the fish through the eyes of scientists in the field. Each chapter focuses on a portion of the salmon's journey to and from their natal streams; on one of the five Pacific...
Integrated Restoration of Forested Ecosystems to Achieve Multiresource Benefits
"A primary mission of the U.S. Department of Agriculture Forest Service is multiple resource management, and one of the emerging themes is forest restoration. The National Silviculture Workshop, a biennial event co-sponsored by the Forest Service, was held May 7-10, 2007, in Ketchikan, Alaska, with the theme of "Integrated Restoration of Forested Ecosystems to Achieve Multiresource Benefits." This proceedings presents a compilation of state-of-the-art silvicultural research and forestry management papers that demonstrates integrated restoration to yield multiple resource benefits. These papers highlight national perspectives on ecosystem services, forest restoration and climate change, and regional perspectives on forest restoration and silvicultural practices to achieve multiple resource benefits from researchers and forest practitioners working in a broad array of forest types in the United States."
