Evaluation of modeled bacteria loads along an impaired stream reach receiving discharge from a municipal separate storm sewer system in Independence, Mo.
Allison Flickinger, Eric D. Christensen
2017, Conference Paper, Proceedings of the Water Environment Federation, WEFTEC 2017
The Little Blue River in Jackson County, Missouri, was listed as impaired in 2012 due to Escherichia coli (E. coli) from urban runoff and storm sewers. A study was initiated to characterize E. coli concentrations and loads to aid in the development of a total maximum daily load implementation plan. Longitudinal sampling along the...
Disentangling the complexities of how legumes and their symbionts regulate plant nitrogen access and storage
Sasha C. Reed
2017, New Phytologist (213) 478-480
Nitrogen (N) availability strongly influences the structure and function of ecosystems (e.g. Vitousek & Howarth, 1991), but only a relatively small number of microbial groups have the ability to convert the N2 in our atmosphere into biologically available forms.This process,...

Investigating impacts of oil and gas development on greater sage-grouse
Adam Green, Cameron L. Aldridge, Michael S. O’Donnell
2017, Journal of Wildlife Management (81) 46-57
The sagebrush (Artemisia spp.) ecosystem is one of the largest ecosystems in western North America providing habitat for species found nowhere else. Sagebrush habitats have experienced dramatic declines since the 1950s, mostly due to anthropogenic disturbances. The greater sage-grouse (Centrocercus urophasianus) is a sagebrush-obligate species that has experienced population declines over...
Impacts of mesquite distribution on seasonal space use of lesser prairie-chickens
Matthew A. Boggie, Cody R. Strong, Daniel Lusk, Scott A. Carleton, William R. Gould, Randy L. Howard, Clay T. Nichols, Michael J. Falkowski, Christian A. Hagen
2017, Rangeland Ecology and Management (70) 68-77
Loss of native grasslands by anthropogenic disturbances has reduced availability and connectivity of habitat for many grassland species. A primary threat to contiguous grasslands is the encroachment of woody vegetation, which is spurred by disturbances that take on many forms from energy development, fire suppression, and grazing. These disturbances are...
What can volunteer angler tagging data tell us about the status of the Giant Trevally (ulua aukea) Caranx ignobilis fishery in Hawaii: revisiting data collected during Hawaii’s Ulua and Papio Tagging Project 2000-2016
Timothy B. Grabowski, Erik C. Franklin
2017, Cooperator Science Series FWS/CSS-126-2017
Giant Trevally (ulua aukea) Caranx ignobilis is one of the most highly prized and frequentlytargeted nearshore species. However, there is very little information on its current status inHawaiian waters. This study uses mark-recapture data collected as part of recreational anglertagging program conducted by the Hawaii Department of Land and Natural...

2017, Rangeland Ecology and Management (70) 15-24
Invasive woody plant expansion is a primary threat driving fragmentation and loss of sagebrush (Artemisia spp.) and prairie habitats across the central and western United States. Expansion of native woody plants, including conifer (primarily Juniperus spp.) and mesquite (Prosopis spp.), over the past century is primarily attributable to wildfire suppression, historic periods of intensive...
Social-ecological outcomes in recreational fisheries: The interaction of lakeshore development and stocking
Jacob P. Ziegler, Elizabeth J. Golebie, Stuart E. Jones, Brian Weidel, Christopher T. Solomon
2017, Ecological Applications (27) 56-65
Many ecosystems continue to experience rapid transformations due to processes like land use change and resource extraction. A systems approach to maintaining natural resources focuses on how interactions and feedbacks among components of complex social‐ecological systems generate social and ecological outcomes. In recreational fisheries, residential shoreline development and fish stocking...

2017, Book chapter, From the Blue Ridge to the beach Geological field excursions across Virginia
The 295-300 Ma Petersburg batholith in east-central Virginia forms one of the largest and northernmost of the Alleghanian plutonic complexes in the southern Appalachian Piedmont. The batholith is primarily composed of granite including massive and foliated (both magmatic and solid-state fabrics) varieties. The plutonic complex intruded medium-grade metamorphosed volcanic/plutonic rocks...

Detailed geologic mapping and new SHRIMP (sensitive high-resolution ion microprobe) U-Pb zircon, Ar/Ar, Lu-Hf, 14C, luminescence (optically stimulated), thermochronology (fission-track), and palynology reveal the complex Mesoproterozoic to Quaternary geology along the ~350 km length of the Blue Ridge Parkway in Virginia. Traversing the boundary of the central and southern Appalachians, rocks...
Adaptive management of rangeland systems

Lake Lungo and Lake Ripasottile are two shallow (4-5 m) lakes located in the Rieti Basin, central Italy, that have been described previously as surface outcroppings of the groundwater table. In this work, the two lakes as well as springs and rivers that represent their potential source waters are characterized...
Long-term changes in Canade Goose nest success and nest densities at an Iowa wetland complex
Brenna N. Ness, Robert W. Klaver, G. G. Zenner
2017, Prairie Naturalist (49) 37-40
Giant Canada geese (Branta canadensis maxima) were extirpated from Iowa by the early 1900s due to unregulated hunting, egg gathering, and wetland drainage in the nineteenth century (Bishop 1978). Ef- forts to reintroduce Canada geese in Iowa began in 1964 (Bishop and Howing 1972) and involved releasing flightless adults and...
Comparison of oyster populations, shoreline protection service, and site characteristics at seven created fringing reefs in Louisiana: Key parameters and responses to consider
Megan K. LaPeyre, Lindsay Schwarting Miller, Shea Miller, Earl Melancon
2017, Book chapter, Living shorelines: The science and management of nature-based coastal protection
Coastal erosion threatens many low-lying areas around the globe. Rising sea levels from climate change are expected to increase coastal erosion and exacerbate flooding and storm surges. This is particularly true in low-lying coastal Louisiana, which developed as the Mississippi River changed course (delta switching) over the past 7000 years....

2017, PLoS ONE (12) 1-15
The North American beaver (Castor canadensis) is a managed species in the United States. In northern Wisconsin, as part of the state-wide beaver management program, the Chequamegon-Nicolet National Forest removes beavers from targeted trout streams on U.S. Forest Service lands. However, the success of this management program has not been...
The response of arid soil communities to climate change: Chapter 8
Blaire Steven, Theresa Ann McHugh, Sasha C. Reed
2017, Book chapter, The biology of arid soils
Arid and semiarid ecosystems cover approximately 40% of Earth’s terrestrial surface and are present on each of the planet’s continents [1]. Drylands are characterized by their aridity, but there is substantial geographic, edaphic, and climatic variability among these vast ecosystems, and these differences underscore substantial variation in dryland soil microbial...

Elliott Matchett, Michael L. Casazza, Joseph P. Fleskes, T. Kelman, M. Cadena, M. Pitesky
2017, Conference Paper, Proceedings of the Sixty-Sixth Western Poultry Disease Conference
Wildlife researchers frequently study resource and habitat selection of wildlife to understand their potential habitat requirements and to conserve their populations. Understanding wildlife spatial-temporal distributions related to habitat have other applications such as to model interfaces between wildlife and domestic food animals in order to mitigate disease transmission to food...
Determination of habitat requirements for Apache Trout
Sally J. Petre, Scott A. Bonar
2017, Transactions of the American Fisheries Society (146) 1-15
The Apache Trout Oncorhynchus apache, a salmonid endemic to east-central Arizona, is currently listed as threatened under the U.S. Endangered Species Act. Establishing and maintaining recovery streams for Apache Trout and other endemic species requires determination of their specific habitat requirements. We built upon previous studies of Apache Trout habitat by...

Sarah Flanagan, Joseph P. Levitt, Joseph D. Ayotte
2017, Environmental Science & Technology (51) 1168-1175
In southeast New Hampshire, where reformulated gasoline was used from the 1990s to 2007, methyl tert-butyl ether (MtBE) concentrations ≥0.2 μg/L were found in water from 26.7% of 195 domestic wells sampled in 2005. Ten years later in 2015, and eight years after MtBE was banned, 10.3% continue to have MtBE....
