Book The Forest Ecosystem of Southeast Alaska

Download or read book The Forest Ecosystem of Southeast Alaska written by William R. Meehan and published by . This book was released on 1974 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of logging and associated activities on fish habitat in southeastern Alaska are discussed, and fish habitat research applicable to southeast Alaska is summarized. Requirements of salmonids for suitable spawning and rearing areas are presented. Factors associated with timber harvest which may influence these habitats are discussed in detail; e.g., sediment, stream temperature, streamflow, logging debris, and chemicals. Recommendations for further research are made.

Book Riparian and Aquatic Habitats of the Pacific Northwest and Southeast Alaska

Download or read book Riparian and Aquatic Habitats of the Pacific Northwest and Southeast Alaska written by Fred H. Everest and published by . This book was released on 2007 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of riparian habitats is controversial because land use policies have historically emphasized economic values (e.g., timber production) at the expense of ecological and social values. Attempting to manage these valuable resources to attain the greatest combination of benefits has created a long-term controversy that continues to the present. Our analysis indicates that at mid to large spatial scales, healthy riparian ecosystems and land management activities are not mutually exclusive, but the degree of compatibility is determined by policy decisions based on competing demands and pressing timelines as well as available scientific knowledge. Current management schemes on federal lands in the Pacific Northwest and Alaska are appropriately addressing large spatial scales and incorporating the principles of disturbance ecology. We found no scientific evidence that either the default prescriptions or the options for watershed analysis in the Northwest Forest Plan and Tongass Land Management Plan provide more protection than necessary to meet stated riparian management goals. We believe that additional alternative riparian management strategies could be implemented and evaluated in concert to shorten the time needed to realize effective strategies that fully meet riparian management goals.

Book Past and present aquatic habitats and fish populations of the Yazoo Mississippi Delta

Download or read book Past and present aquatic habitats and fish populations of the Yazoo Mississippi Delta written by Mason D. Bryant and published by . This book was released on 2010 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this review and synthesis of the literature, published and unpublished, is to describe the major processes that shape and influence the aquatic habitats and fish communities in the Yazoo-Mississippi Delta (YMD) and to outline a program of research. The YMD is influenced by the large geographic and temporal scales of the Mississippi River watershed. It extends over 41 percent of the contiguous United States. The Mississippi River has existed in its current location for more than 1.2 million years, and ancient fish species are still present in the watershed. About 9,500 years BP, the Mississippi River formed into a predominantly meandering channel from which most of the aquatic habitats in the YMD developed. Oxbows formed in the meander belts shape the topography of the YMD and are a fundamental part of the development of the aquatic habitat of the YMD. Seasonal floods are keystone events in the YMD, but the process is altered substantially from its previous natural state. Levees, flood control structures, land use practices, and loss of large wood in river channels have modified natural processes throughout most of the YMD. However, most of the larger fish species present during aboriginal occupation of the YMD are still present. Given the large-scale loss of habitat throughout the YMD and the deterioration of water quality, the abundance and diversity of fish likely have declined. In the past few years, management of aquatic habitats in the YMD has centered on mitigating and preventing some of the adverse effects of anthropogenic disturbance. A program of "naturalization" to move aquatic ecosystem processes closer to natural conditions is possible within the context of socioeconomic constraints. The research approach proposed in this paper provides a model to develop an understanding of the fish and aquatic habitat that can contribute to a sustainable restoration program.

Book Evolution and the Aquatic Ecosystem

Download or read book Evolution and the Aquatic Ecosystem written by Jennifer L. Nielsen and published by . This book was released on 1995 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides empirical, theoretical, and philosophical insights into the evolution of aquatic ecosystems from perspectives that range from molecular and cellular biology to ecology and behavior. The 36 papers and panel discussions were reviewed across disciplines and presented at a May 1994 conference in Monterey, California. They cover general perspectives, morphology and systematics, behavior and life history, genetics, and ecosystems and habitat.
