State-of-the-Art for Assessing Earthquake Hazards in the United States: Report 19, The Evidence for Reservoir-Induced Macroearthquakes

Description: Partial abstract: "The published evidence of reservoir-induced macroearthquakes is critically reviewed. The evidence is partitioned into three types: (a) evidence of a post-impoundment increase in seismicity, (b) correlation evidence that is composed of a plot of a reservoir variable and a seismicity variable and, in most cases, an auxiliary variable, time, and (c) evidence based on the slope of the magnitude-frequency relationship (b value evidence)."

Large-Scale Operations Management Test of Use of the White Amur for Control of Problem Aquatic Plants, Report 2: First Year Poststocking Results, Volume 2: The Fish, Mammals, and Waterfowl of Lake Conway, Florida

Description: Abstract: "Fish, waterfowl and wading birds, and aquatic mammal populations on Lake Conway were surveyed for 1 year after the introduction of the herbivorous fish, white amur (Ctenopharyngodon idella). Low water levels reduced littoral zone area, which lead to stunted panfish and poorer condition of largemouth bass. Vegetated samples supported more diverse fish populations than beach sites. White amur and migratory waterfowl consumed the same plant foods; continued reduction of submerged plants… more
