Available in PDF, EPUB and Kindle. Book excerpt: Four study sites each the length of one meander scar were measured on into the lower Sabine River, below the Toledo Bend Reservoir, to sample the LWD within and around the bank channel. All LWD within the sample sites were measured, identified, and categorized into eight major sections, the eight sections were: degree of decay, branch presence, potential source, origin, bank orientation, root wad presence, position, and stage contact. To measure the bankside vegetation 0.04 hectare plots were inserted 20 meters from the bank. All trees were measured, identified, and their distance from the bank was recorded. Field work on LWD and bankside vegetation began in Fall 2006 and continued throughout the Summer of 2008. The site closest to the Toledo Bend Reservoir, the Burkeville site, contained a significantly greater amount of LWD volume, since the local geomorphic processes combined with the vegetation characteristics have the largest impact on LWD recruitment more bankside erosion results in greater LWD input. The Burkeville site contained 85.29 cubic meters per kilometer of LWD, the Bon Wier site had 29.67, Deweyville had 49.63, and the Southern site had 13.29 cubic meters per kilometer. A significantly greater amount of decayed wood was found at the Southern site compared to the other three study sites, which indicated that more decayed wood was found the further south the site was on the Sabine. The snagging of the Southern site several years back showed that it would take about 12 years for the LWD volume in the Sabine to replenish back to "natural" LWD volumes. Future LWD volumes and recruitment rates will depend on maintaining optimum riparian forest structure.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The removal of two dams on the Elwha River, Washington, exposed over 300 hectares of reservoir sediments and created primary successional habitats that posed challenges to revegetation efforts. In order to meet Elwha restoration goals, coarse sediment deposits would require revegetation methods aimed at quickly restoring native vegetation while deterring exotic species invasions. I examined the effect of two restoration treatments--large woody debris translocations and native seed enhancements--on plant species composition on novel terraces in the former Lake Mills reservoir four years after dam removal. I sampled vegetation in seeded and unseeded treatment areas with and without large woody debris. I also examined species composition and seed dispersal mechanisms to determine whether distance limited native plant recruitment from the nearby forest edge. I used two-way analysis of variance, NMDS ordinations, and permutational multivariate analysis of variance to determine whether wood placements, seeding treatments, and distance from the forest influenced species composition on novel terraces. My results revealed that Shannon-Weiner diversity, species richness, and percent exotics increased on plots containing wood, compared with surrounding bare sediments, but plant establishment did not substantially increase on wood plots. Plots located in seeded treatment areas had higher species richness and plant abundance, with decreased exotic species recruitment. As distance from the forest edge increased, Shannon-Weiner diversity, species richness, and percent exotics on unseeded plots declined, but plant abundance did not change significantly with distance. In addition, a greater proportion of plants were wind-dispersed at greater distances, while plants dispersed by gravity and ballistic mechanisms were associated with closer distances to the forest edge. This study's results help fill a knowledge gap regarding the efficacy of using translocated large woody debris and direct seeding to restore vegetation in primary successional habitats following dam removal and helps inform best practices regarding the use of these restoration methods at future dam removal projects.

Download or read book Eutrophication causes consequences and control written by Abid A. Ansari and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

Available in PDF, EPUB and Kindle. Book excerpt: "The Freshwater Mussels of Tennessee . . . is indispensable to anyone, anywhere, working on this group. Parmalee and Bogan have written a work that sets the standard for future regional guides."--G. Thomas Watters, Ohio Biological Survey "The Freshwater Mussels of Tennessee documents a tremendously diverse and unique mussel fauna that is rapidly being destroyed by modern development. Parmalee and Bogan set a new standard for state mussel surveys in their authoritative, thorough, and and highly readable account. The book will be of interest to biologists and conservationists worldwide and will appeal to anyone who cares about the preservation of natural resources in the southeastern United States."--Robert E. Warren, Illinois State Museum With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat--twenty-three are currently listed as endangered species and at least twelve have become extinct. This is the first book for Tennessee to deal with this biologically and commercially significant group of mollusks. Its authors have been studying and writing about the mussels of Tennessee for more than twenty years and have undertaken a systematic organization of a large and complex body of information to bring order to a difficult field. The book traces the long history of human exploitation of mussels, from aboriginal food gathering to the growth of the cultured pearl industry. It provides an interpretive context for its exhaustive species accounts with background material on biology, distribution, economic utilization, taxonomy, and conservation issues. The authors also review the life cycle of the mussel and describe its many remarkable traits, such as its shell formation and the strategies it employs during the larval stage in parasitizing fish. The species accounts comprise 128 members of Family Unionidae--from pigtoes and pocketbooks to lilliputs and spikes--plus four additional species. The authors cover classification and synonymy, range and distribution, life history and ecology, and survival status. Particular attention is paid to shell description and structure to assist the reader in identification. Each species account includes a distribution map and color photos of two specimens. The Freshwater Mussels of Tennessee is a major reference that encompasses historical and modern mussel collections and draws on conservation studies that span two centuries. It will stand as an authoritative guide to understanding Tennessee mollusks and as a benchmark in the study of these species worldwide. The Authors: Paul W. Parmalee is professor emeritus of zooarchaeology and director emeritus of the McClung Museum at the University of Tennessee, Knoxville. Arthur E. Bogan is curator of aquatic invertebrates at the North Carolina State Museum of Natural Sciences, Raleigh.
