Joan F. Kenny, Kyle E. Juracek
2012, Scientific Investigations Report 2012-5163
Domestic water-use and related socioeconomic and climatic data for 2005-10 were used in an analysis of 21 selected U.S. cities to describe recent domestic per capita water use, investigate variables that potentially affect domestic water use, and provide guidance for estimating domestic water use. Domestic water use may be affected...

Jeffrey E. Lovich, Norman J. Scott Jr., R. Bruce Bury, C. Kenneth Dodd Jr., Roy W. McDiarmid
2012, Herpetological Conservation and Biology (7)
The U.S. Department of the Interior (DOI) has a long and distinguished history of employing herpetologists to conduct basic and applied research to better manage amphibian and reptile populations on public lands and even outside the boundaries of the United States. This history extends back over 125 years with roots...

Mohamed Naimi, Mohammed Znari, Jeffrey E. Lovich, Youssef Feddadi, Moulay Abdeljalil Ait Baamrane
2012, Herpetological Journal (22) 43-49
We examined the relationships of clutch size (CS) and egg size to female body size (straight-line carapace length, CL) in a population of the turtle Mauremys leprosa from a polluted segment of oued (river) Tensift in arid west-central Morocco. Twenty-eight adult females were collected in May–July, 2009 and all were...
Semi-discrete biomass dynamic modeling: an improved approach for assessing fish stock responses to pulsed harvest events
Clay Pierce, Michael E. Colvin, Timothy W. Stewart
2012, Canadian Journal of Fisheries and Aquatic Sciences (69) 1710-1721
Continuous harvest over an annual period is a common assumption of continuous biomass dynamics models (CBDMs); however, fish are frequently harvested in a discrete manner. We developed semidiscrete biomass dynamics models (SDBDMs) that allow discrete harvest events and evaluated differences between CBDMs and SDBDMs using an equilibrium yield analysis with...
Optimal egg size in a suboptimal environment: reproductive ecology of female Sonora mud turtles (Kinosternon sonoriense) in central Arizona, USA
Jeffrey E. Lovich, Sheila V. Madrak, Charles A. Drost, Anthony J. Monatesti, Dennis Casper, Mohammed Znari
2012, Amphibia-Reptilia (33) 161-170
We studied the reproductive ecology of female Sonora mud turtles (Kinosternon sonoriense) at Montezuma Well, a chemically-challenging natural wetland in central Arizona, USA. Females matured between 115.5 and 125 mm carapace length (CL) and 36-54% produced eggs each year. Eggs were detected in X-radiographs from 23 April-28 September (2007-2008) and...

2012, Conference Paper, Proceedings of the 15th World Conference on Earthquake Engineering, Portugal, 2012
Five new directivity models are being developed for the NGA-West 2 project. All are based on the NGA-West 2 data base, which is considerably expanded from the original NGA-West data base, containing about 3,000 more records from earthquakes having finite-fault rupture models. All of the new directivity models have parameters...
Toxicity of copper to early-life stage Kootenai River white sturgeon, Columbia River white sturgeon, and rainbow trout
E. E. Little, R.D. Calfee, G. Linder
2012, Archives of Environmental Contamination and Toxicology (63) 400-408
White sturgeon (Acipenser transmontanus) populations throughout western North America are in decline, likely as a result of overharvest, operation of dams, and agricultural and mineral extraction activities in their watersheds. Recruitment failure may reflect the loss of early-life stage fish in spawning areas of the upper Columbia River, which are...

Victoria G. Christensen, Kathy Lee, James M. McLees, Scott L. Niemela
2012, Journal of Environmental Quality (41) 1459-1472
The relative importance of agricultural land retirement on water quality and aquatic-community health was investigated in the Minnesota River Basin. Eighty-two sites, with drainage areas ranging from 4.3 to 2200 km2, were examined for nutrient concentrations, measures of aquatic-community health (e.g., fish index of biotic integrity [IBI] scores), and environmental...
Estimation of evaporation from open water - A review of selected studies, summary of U.S. Army Corps of Engineers data collection and methods, and evaluation of two methods for estimation of evaporation from five reservoirs in Texas
Glenn R. Harwell
2012, Scientific Investigations Report 2012-5202
Organizations responsible for the management of water resources, such as the U.S. Army Corps of Engineers (USACE), are tasked with estimation of evaporation for water-budgeting and planning purposes. The USACE has historically used Class A pan evaporation data (pan data) to estimate evaporation from reservoirs but many USACE Districts have...
Inferring local competition intensity from patch size distributions: a test using biological soil crusts
Matthew A. Bowker, Fernando T. Maestre
2012, Oikos (121) 1914-1922
Dryland vegetation is inherently patchy. This patchiness goes on to impact ecology, hydrology, and biogeochemistry. Recently, researchers have proposed that dryland vegetation patch sizes follow a power law which is due to local plant facilitation. It is unknown what patch size distribution prevails when competition predominates over facilitation, or if...
Toxicity, sublethal effects, and potential modes of action of select fungicides on freshwater fish and invertebrates
Adria A. Elskus
2012, Open-File Report 2012-1213
Despite decades of agricultural and urban use of fungicides and widespread detection of these pesticides in surface waters, relatively few data are available on the effects of fungicides on fish and invertebrates in the aquatic environment. Nine fungicides are reviewed in this report: azoxystrobin, boscalid, chlorothalonil, fludioxonil, myclobutanil, fenarimol, pyraclostrobin,...

Experiments suggest that biodiversity enhances the ability of ecosystems to maintain multiple functions, such as carbon storage, productivity, and the buildup of nutrient pools (multifunctionality). However, the relationship between biodiversity and multifunctionality has never been assessed globally in natural ecosystems. We report here on a global empirical study relating plant...
Changes in sources and storage in a karst aquifer during a transition from drought to wet conditions
C.I. Wong, B.J. Mahler, M. Musgrove, J.L. Banner
2012, Journal of Hydrology (468-469) 159-172
Understanding the sources and processes that control groundwater compositions and the timing and magnitude of groundwater vulnerability to potential surface-water contamination under varying meteorologic conditions is critical to informing groundwater protection policies and practices. This is especially true in karst terrains, where infiltrating surface water can rapidly affect groundwater quality....

Ran Meng, Philip E. Dennison, Levi R. Jamison, Charles van Riper III, Pamela Nager, Kevin R. Hultine, Dan W. Bean, Tom Dudley
2012, GIScience and Remote Sensing (49) 510-537
The spread of tamarisk (Tamarix spp., also known as saltcedar) is a significant ecological disturbance in western North America and has long been targeted for control, leading to the importation of the northern tamarisk beetle (Diorhabda carinulata) as a biological control agent. Following its initial release along the Colorado River...
