Development of a bioenergetics model for age-0 American Shad
Sally T. Sauter
2011, Report, Impact of American Shad in the Columbia River
Bioenergetics modeling can be used as a tool to investigate the impact of non-native age-0 American shad (Alosa sapidissima) on reservoir and estuary food webs. The model can increase our understanding of how these fish influence lower trophic levels as well as predatory fish populations that feed on juvenile salmonids....

Studies of metamorphic core complexes in this region report extension beginning in the early Cenozoic or even Late Cretaceous, peaking in the Eocene and...
Evaluating the variability of sediment and nutrient loading from riverine systems into Texas estuaries and bays
Michael T. Lee
2011, Fact Sheet 2011-3036
The water quality in estuaries and bays and the health of these coastal ecosystems are affected by sediment and nutrient loads transported by streams. Large sediment loads delivered to an estuary or bay can degrade water quality. Concentrations of suspended sediment are affected by natural conditions (such as soil erosion...
Growth characteristics and Otolith analysis on Age-0 American Shad
Sally T. Sauter, Lisa A. Wetzel
2011, Report, Impact of American Shad in the Columbia River
Otolith microstructure analysis provides useful information on the growth history of fish (Campana and Jones 1992, Bang and Gronkjaer 2005). Microstructure analysis can be used to construct the size-at-age growth trajectory of fish, determine daily growth rates, and estimate hatch date and other ecologically important life history events (Campana and...

Lisa A. Wetzel, Michael J. Parsley, Bjorn K. van der Leeuw, Kimberly A. Larsen
2011, Report, Impact of American Shad in the Columbia River
American shad Alosa sapidissima fry were successfully transplanted from the Atlantic to the Pacific coast in 1871 and have subsequently proliferated. The Columbia River population is in the millions, yet few investigations have been conducted to better understand their life history, population dynamics, or potential impacts on other species. In...

Effects of dams in river networks on fish assemblages in non-impoundment sections of rivers in Michigan and Wisconsin, USA
Jana S. Stewart, Lizhu Wang, Dana M. Infante, John D. Lyons, Arthur Cooper
2011, River Research and Applications (27) 473-487
Regional assessment of cumulative impacts of dams on riverine fish assemblages provides resource managers essential information for dam operation, potential dam removal, river health assessment and overall ecosystem management. Such an assessment is challenging because characteristics of fish assemblages are not only affected by dams, but also influenced by natural...

Climate change links fate of glaciers and an endemic alpine invertebrate
Clint C. Muhlfeld, J. Joseph Giersch, F. Richard Hauer, Gregory T. Pederson, Gordon Luikart, Douglas P. Peterson, Christopher C. Downs, Daniel B. Fagre
2011, Climatic Change (106) 337-345
Climate warming in the mid- to high-latitudes and high-elevation mountainous regions is occurring more rapidly than anywhere else on Earth, causing extensive loss of glaciers and snowpack. However, little is known about the effects of climate change on alpine stream biota, especially invertebrates. Here, we show a strong linkage between...
