DOWNLOAD EBOOK →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.

Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
