Nathan M. Bacheler, Joseph E. Hightower, Summer M. Burdick, Lee M. Paramore, Jeffrey A. Buckel, Kenneth H. Pollock
2010, Fisheries Research (102) 266-275
Estimating the selectivity patterns of various fishing gears is a critical component of fisheries stock assessment due to the difficulty in obtaining representative samples from most gears. We used short-term recoveries (n = 3587) of tagged red drum Sciaenops ocellatus to directly estimate age- and length-based selectivity patterns using generalized linear models. The most...

2010, Mine Water and the Environment (29) 176-199
Acidic mine drainage (AMD) from legacy anthracite mines has contaminated Swatara Creek in eastern Pennsylvania. Intermittently collected base-flow data for 1959–1986 indicate that fish were absent immediately downstream from the mined area where pH ranged from 3.5 to 7.2 and concentrations of sulfate, dissolved iron, and dissolved aluminum were as...

Leandro E. Miranda, M. Spickard, T. Dunn, K.M. Webb, J.N. Aycock, K. Hunt
2010, Fisheries (35) 175-184
As the median age of the thousands of large reservoirs (> 200 ha) in the United States tops 50, many are showing various signs of fish habitat degradation. Our goal was to identify major factors degrading fish habitat in reservoirs across the country, and to explore regional degradation patterns. An...
Reconnaissance geochronology of tuffs in the Miocene Barstow Formation: Implications for basin evolution and tectonics in the central Mojave Desert
David M. Miller, Shannon R. Leslie, John W. Hillhouse, Joseph L. Wooden, Jorge A. Vazquez, R. E. Reynolds
2010, Conference Paper, Overboard in the Mojave: 20 million years of lakes and wetlands
Early to middle Miocene lacustrine strata of the Barstow Formation are well dated in just a few places, limiting our ability to infer basin evolution and regional tectonics. At the type section in the Mud Hills, previous studies have shown that the lacustrine interval of the Barstow Formation is between...

Joan S. Daniels, Brian S. Cade, James J. Sartoris
2010, Wetlands (30) 231-239
Assessment of emergent vegetation biomass can be time consuming and labor intensive.

Sandra K. Poppenga, Bruce B. Worstell, Jason M. Stoker, Susan K. Greenlee
2010, Scientific Investigations Report 2010-5059
Digital elevation data commonly are used to extract surface flow features. One source for high-resolution elevation data is light detection and ranging (lidar). Lidar can capture a vast amount of topographic detail because of its fine-scale ability to digitally capture the surface of the earth. Because elevation is a key...
