Thomas A. Worthington, Shannon K. Brewer, Timothy B. Grabowski, Julia Mueller
2013, North American Journal of Fisheries Management (33) 79-88
Quantitative studies focusing on the collection of semibuoyant fish eggs, which are associated with a pelagic broadcast-spawning reproductive strategy, are often conducted to evaluate reproductive success. Many of the fishes in this reproductive guild have suffered significant reductions in range and abundance. However, the efficiency of the sampling gear used...

Ryan A. Hill, Charles P. Hawkins, Daren M. Carlisle
2013, Freshwater Science (32) 39-55
Temperature is a primary driver of the structure and function of stream ecosystems. However, the lack of stream temperature (ST) data for the vast majority of streams and rivers severely compromises our ability to describe patterns of thermal variation among streams, test hypotheses regarding the effects of temperature on macroecological...

Chester C. Wastson, Robert R. Holmes Jr., David S. Biedenham
2013, Journal of Hydraulic Engineering (139) 1062-1070
Streamflow measurement techniques of the Mississippi River at St. Louis have changed through time (1866–present). In addition to different methods used for discrete streamflow measurements, the density and range of discrete measurements used to define the rating curve (stage versus streamflow) have also changed. Several authors have utilized published water...
Methylmercury is the predominant form of mercury in bird eggs: a synthesis
Joshua T. Ackerman, Mark P. Herzog, Steven E. Schwarzbach
2013, Environmental Science & Technology (47) 2052-2060
Bird eggs are commonly used in mercury monitoring programs to assess methylmercury contamination and toxicity to birds. However, only 6% of >200 studies investigating mercury in bird eggs have actually measured methylmercury concentrations in eggs. Instead, studies typically measure total mercury in eggs (both organic and inorganic forms of mercury),...
A support system for assessing local vulnerability to weather and climate
Alex Coletti, Peter D. Howe, Brent Yarnal, Nathan J. Wood
2013, Natural Hazards (65) 999-1008
The changing number and nature of weather- and climate-related natural hazards is causing more communities to need to assess their vulnerabilities. Vulnerability assessments, however, often require considerable expertise and resources that are not available or too expensive for many communities. To meet the need for an easy-to-use, cost-effective vulnerability assessment...
Testing the use of microfossils to reconstruct great earthquakes at Cascadia
S. E. Engelhart, B. P Horton, Alan R. Nelson, A. D. Hawkes, Robert C. Witter, K. Wang, P.-L. Wang, C. H. Vane
2013, Geology (41) 1067-1070
Coastal stratigraphy from the Pacific Northwest of the United States contains evidence of sudden subsidence during ruptures of the Cascadia subduction zone. Transfer functions (empirical relationships between assemblages and elevation) can convert microfossil data into coastal subsidence estimates. Coseismic deformation models use the subsidence values to constrain earthquake magnitudes. To...

User's guide and metadata for WestuRe: U.S. Pacific Coast estuary/watershed data and R tools
M.R. Frazier, D.A. Reusser, H. Lee II, L.M. McCoy, C. Brown, W. Nelson
2013, Report
Overview There are about 350 estuaries along the U.S. Pacific Coast (U.S. Fish andWildlife 2011). Basic descriptive data for these estuaries, such as their size and watershed area, are important for coastal-scale research and conservation planning. However, this information is spread among many sources, making it difficult to find and standardize....
Modeling trends from North American Breeding Bird Survey data: a spatially explicit approach
Florent Bled, John R. Sauer, Keith L. Pardieck, Paul Doherty, J. Andy Royle
2013, PLoS ONE (8)
Population trends, defined as interval-specific proportional changes in population size, are often used to help identify species of conservation interest. Efficient modeling of such trends depends on the consideration of the correlation of population changes with key spatial and environmental covariates. This can provide insights into causal mechanisms and allow...
