2013, North American Journal of Fisheries Management (33) 1179-1183
We assessed the physiological stress responses (i.e., plasma levels of cortisol, glucose, and lactate) of adult Rainbow Trout Oncorhynchus mykiss at selected time intervals after they had passed a distance of 15 m through a unique fish conveyance device (treatment fish) or not (controls). This device differs from traditional fish...
Spatio-temporal variability in movement, age, and growth of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry
Joseph R. Benjamin, Lisa A. Wetzel, Kyle D. Martens, Kimberly Larsen, Patrick J. Connolly
2013, Canadian Journal of Fisheries and Aquatic Sciences (70) 1-10
Connectivity of river networks and the movements among habitats can be critical for the life history of many fish species, and understanding of the patterns of movement is central to managing populations, communities, and the landscapes they use. We combined passive integrated transponder tagging over 4 years and strontium isotopes...
The impact of small irrigation diversion dams on the recent migration rates of steelhead and redband trout (Oncorhynchus mykiss)
Dana E. Weigel, Patrick J. Connolly, Madison S. Powell
2013, Conservation Genetics (14) 1255-1267
Barriers to migration are numerous in stream environments and can occur from anthropogenic activities (such as dams and culverts) or natural processes (such as log jams or dams constructed by beaver (Castor canadensis)). Identification of barriers can be difficult when obstructions are temporary or incomplete providing passage periodically. We...
The National assessment of shoreline shange—A GIS compilation of vector shorelines and associated shoreline change data for the Pacific Northwest coast
Meredith G. Kratzmann, Emily A. Himmelstoss, Peter Ruggiero, E. Robert Thieler, David Reid
2013, Open-File Report 2012-1008
Sandy ocean beaches are a popular recreational destination and are often surrounded by communities that consist of valuable real estate. Development along sandy coastal areas is increasing despite the fact that coastal infrastructure may be repeatedly subjected to flooding and erosion. As a result, the demand for accurate information regarding...

Peter Ruggerio, Meredith G. Kratzmann, Emily A. Himmelstoss, David Reid, Jonathan Allan, George Kaminsky
2013, Open-File Report 2012-1007
Beach erosion is a chronic problem along most open ocean shores of the United States. As coastal populations continue to increase and infrastructure is threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need for...

Sediment transport and deposition in the lower Missouri River during the 2011 flood
Jason S. Alexander, Robert B. Jacobson, David L. Rus
2013, Professional Paper 1798-F
Floodwater in the Missouri River in 2011 originated in upper-basin regions and tributaries, and then travelled through a series of large flood-control reservoirs, setting records for total runoff volume entering all six Missouri River main-stem reservoirs. The flooding lasted as long as 3 months. The U.S Geological Survey (USGS) examined...

Edward R. Banta, David P. Ahlfeld
2013, Techniques and Methods 6-A48
Groundwater Management–Version Independent (GWM–VI) is a new version of the Groundwater Management Process of MODFLOW. The Groundwater Management Process couples groundwater-flow simulation with a capability to optimize stresses on the simulated aquifer based on an objective function and constraints imposed on stresses and aquifer state. GWM–VI extends prior versions of...

2013, Aeolian Research (11) 85-99
Contemporary glaciogenic dust has not received much attention, because most research has been on glaciogenic dust of the last glacial period or non-glaciogenic dust of the present interglacial period. Nevertheless, dust from modern glaciogenic sources may be important for Fe inputs to primary producers in the ocean. Adjacent to the...

Trichinosis
William J. Foreyt, Rachel C. Abbott, Charles van Riper III
2013, Circular 1388
Trichinosis, or trichinellosis, is one of the most widespread global parasitic diseases of humans and animals. This ancient disease is caused by the larval stage of parasitic roundworms (nematodes) in the genus Trichinella. Often called the “trichina worm,” this parasite is considered to be the king of the parasite community,...
Common and distinguishing features of the bacterial and fungal communities in biological soil crusts and shrub root zone soils
Blaire Steven, La Verne Gallegos-Graves, Chris Yeager, Jayne Belnap, Cheryl R. Kuske
2013, Soil Biology and Biochemistry (69) 302-312
Soil microbial communities in dryland ecosystems play important roles as root associates of the widely spaced plants and as the dominant members of biological soil crusts (biocrusts) colonizing the plant interspaces. We employed rRNA gene sequencing (bacterial 16S/fungal large subunit) and shotgun metagenomic sequencing to compare the microbial communities inhabiting...
Sexual dimorphism and feeding ecology of Diamond-backed Terrapins (Malaclemys terrapin)
Elizabeth B. Underwood, Sarah Bowers, Jacquelyn C. Guzy, Jeffrey E. Lovich, Carole A. Taylor, J. Whitfield Gibbons, Michael E. Dorcas
2013, Herpetologica (69) 397-404
Natural and sexual selection are frequently invoked as causes of sexual size dimorphism in animals. Many species of turtles, including the Diamond-backed Terrapin (Malaclemys terrapin), exhibit sexual dimorphism in body size, possibly enabling the sexes to exploit different resources and reduce intraspecific competition. Female terrapins not only have larger body...

Recent studies suggest that coastal ecosystems can bury significantly more C than tropical forests, indicating that continued coastal development and exposure to sea level rise and storms will have global biogeochemical consequences. The Florida Coastal Everglades Long Term Ecological Research (FCE LTER) site provides an excellent subtropical system for examining...

Sara J. Oyler-McCance, Ernest W. Valdez, Thomas J. O’Shea, Jennifer A. Fike
2013, Journal of Mammalogy (94) 1030-1036
Emballonura semicaudata occurs in the southwestern Pacific and populations on many islands have declined or disappeared. One subspecies (E. semicaudata rotensis) occurs in the Northern Mariana Islands, where it has been extirpated from all but 1 island (Aguiguan). We assessed genetic similarity between the last population of E. s....

2013, Rangeland Ecology and Management (66) 657-666
Finding ecologically and economically effective ways to establish matrix species is often critical for restoration success. Wyoming big sagebrush (Artemisia tridentata subsp. wyomingensis) historically dominated large areas of western North America, but has been extirpated from many areas by large wildfires; its re-establishment in these areas often requires active management....
Sampling design for long-term regional trends in marine rocky intertidal communities
Gail V. Irvine, Alice Shelley
2013, Environmental Monitoring and Assessment (185) 6963-6987
Probability-based designs reduce bias and allow inference of results to the pool of sites from which they were chosen. We developed and tested probability-based designs for monitoring marine rocky intertidal assemblages at Glacier Bay National Park and Preserve (GLBA), Alaska. A multilevel design was used that varied in scale and...
