Book Description
Species composition and relative abundance of larval and adult fishes were evaluated in flooded bottomland hardwood wetlands of the Cache River system, Arkansas. Fishes were collected for two consecutive years during the reproductive season (March-June) in the channel and floodplain of the Cache River. Multiple sampling gears were used to evaluate the importance of three distinct habitats: channel, tupelo forest, and oak forest. A total of 10,770 larval and juvenile fishes were collected, representing at least 36 different species. Pirate perch was numerically the most common larval fish species collected. Percidae (darters) was the dominant family, comprising at least seven species and approximately 40 percent of the total number of larval fish collected. Cyprinidae (minnows) and Centrarchidae (sunfish) were the next dominant families. Spotted sucker, channel catfish, and flier were sporadically abundant during the study. More larval fish species were caught in the channel but numerical abundance was highest in the oak habitat. 0 the 32 species collected in the channel, however, 5 species were represented by only a single individual. A total of 30 species were collected in the oak habitat, and this assemblage represented 54 percent of the total number of larval fish collected during the 2-year study. Of these 30 species, 13 taxa were most abundant in this habitat. Cache River system, Hydrology, Wetlands, Collection methods, Spawning, Floodplain habitats, Species composition.

Book Description
This edited volume was originally published in 2000 and presents a comprehensive, interdisciplinary review of issues related to inland flood hazards. It addresses physical controls on flooding, flood processes and effects, and responses to flooding, from the perspective of human, aquatic, and riparian communities. Individual chapter authors are recognized experts in their fields who draw on examples and case studies of inland flood hazards from around the world. This volume is unusual among treatments of flood hazards in that it addresses how the non-occurrence of floods, in association with flow regulation and other human manipulation of river systems, may create hazards for aquatic and riparian communities. This book will be a valuable resource for everyone associated with inland flood hazards: professionals in government and industry, and researchers and graduate students in civil engineering, geography, geology, hydrology, hydraulics, and ecology.

Book Description
The Hydrogeomorphic (HGM) Approach is a collection of concepts and methods for developing functional indices and subsequently using them to assess the capacity of a wetland to perform functions relative to similar wetlands in a region. The approach was initially designed to be used in the context of the Clean Water Act Section 404 Regulatory Program permit review sequence to consider alternatives, minimize impacts, assess unavoidable project impacts, determine mitigation requirements, and monitor the success of mitigation projects. However, a variety of other potential applications for the approach have been identified including: determining minimal effects under the Food Security Act, designing mitigation projects, and managing wetlands. This report uses the HGM Approach to develop a Regional Guidebook for assessing the functions of low gradient, riverine wetlands in western Kentucky. The report begins with a characterization of low gradient, riverine wetlands in the western Kentucky, then discusses (a) the rationale used to select functions, (b)the rationale used to select model variables and metrics, (c) the rational used to develop assessment models, and (d) the data from reference wetlands used to calibrate model variables and assessment models. Finally, it outlines an assessment protocol for using the model variables and functional indices to assess low gradient, riverine wetlands in western Kentucky.

Book Description
The southern forest resource assessment provides a comprehensive analysis of the history, status, and likely future of forests in the Southern United States. Twenty-three chapters address questions regarding social/economic systems, terrestrial ecosystems, water and aquatic ecosystems, forest health, and timber management; 2 additional chapters provide a background on history and fire. Each chapter surveys pertinent literature and data, accesses conditions, identifies research needs, and examines the implications for southern forests and the benefits they provide.
