Fishes Of The Middle Savannah River Basin

The book also discusses the Savannah River, tributary streams, reservoirs, and ponds from the 1950s to the present detailing ecological changes, habitats, and associated fish assemblages."--BOOK JACKET.

From mudminnows and sunfishes to lampreys and sturgeons, the guide describes more than one hundred fifty species of freshwater and coastal estuarine fishes that spend all or major portions of their lives in the fresh waters of South Carolina. For each species the authors provide diagnostic characteristics including size, markings, similar species, and sexual dimorphism as well as information on biology, habitat, and distribution. Color photographs and detailed distribution maps accompany each description. --from publisher description.

While restoration ecology has traditionally aimed to re-create some putative more ‘natural’ ecological state, forest landscape restoration (FLR) has emerged over the last decade as an approach aimed more at restoring natural functions, while focusing on meeting human needs. With a view to exploring the practical potential of this approach, this book draws together a team of experts from the natural and social sciences to discuss its success so far in addressing critical issues such as biodiversity, ecological function, and human livelihoods. Applying principles of landscape ecology, restoration ecology, planning theory and conflict management, the book presents a series of case studies which document the approach, and discusses how the approach can help with priority setting for the future. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

Volume 5 offers an all-inclusive and complete update of the four previously published volumes.--

Total mercury levels were measured in largemouth bass (Micropterus salmoides), ''sunfishes'' (Lepomis spp)., and ''catfish'' (primarily Ameiurus spp.) from 1971 to 2004 in the middle reaches of the Savannah River, which drains the coastal plain of the southeastern U.S. Mercury levels were highest in 1971 but declined over the next ten years due to the mitigation of point sources of industrial pollution. Mercury levels began to increase in the 1980s as a possible consequence of mercury inputs from tributaries and associated wetlands where mercury concentrations were significantly elevated in water and fish. Mercury levels in Savannah River fish decreased sharply in 2001-2003 coincident with a severe drought in the Savannah River basin, but returned to previous levels in 2004 with the resumption of normal precipitation. Regression models showed that mercury levels in Savannah River fish changed significantly over time and were affected by river discharge. Despite temporal changes, there was little overall difference in Savannah River fish tissue mercury levels between 1971 and 2004.

The second edition of Fishes of Arkansas, in development for more than a decade, is an extensive revision and expansion of the first edition, including reclassifications, taxonomic changes, and descriptions of more than thirty new species. An invaluable reference for anyone interested in the state's fish population--from professional ichthyologists, fisheries biologists, and managers of aquatic resources, to amateur naturalists and anglers--this new edition provides updated taxonomic keys as well as detailed descriptions, photographs, and line drawings to aid identification of the state's 241 fish species. There is also much information on the distribution and biology of each species, including descriptions of habitat, foods eaten, reproductive biology, and conservation status. This project and the preparation of this publication was funded in part by a grant from the Arkansas Game and Fish Commission.
