We used the natural abundance of stable isotopic ratios of hydrogen and oxygen in soil (0.05-3 m depth), plant xylem and precipitation to determine the seasonal changes in sources of soil water uptake by two native encroaching woody species (Pinus ponderosa P. & C. Lawson, Juniperus virginiana L.), and two C(4) grasses (Schizachyrium scoparium (Michx.)(More)
Naturally occurring long-term mean annual recharge to ground water in Nebraska was estimated by a novel water-balance approach. This approach uses geographic information systems (GIS) layers of land cover, elevation of land and ground water surfaces, base recharge, and the recharge potential in combination with monthly climatic data. Long-term mean recharge(More)
Female mice were reared in observation incubators from day 1 of life for three weeks. During that time they were continuously exposed to the odors of either cyclooctanone, adult male mouse urine or distilled water. The growth rate was temporarily accelerated for the cyclooctanone-exposed mice. There was no difference in age at sexual maturation of the three(More)
M2DM (multi access services for telematic management of diabetes mellitus, ) is an EU-funded telemedicine project that aims at increasing the quality of diabetes care by improving communication between patients and caregivers. As part of this project, we have undertaken the initial work of describing the necessary requirements (framework) of an advanced(More)
presents the design for the integrated hydrologic observations database that is proposed for the CUAHSI Hydrologic Information System (HIS). An independent review of this design was undertaken to evaluate whether the data model for hydrologic observations meets the needs of the CUAHSI community. Specifically the review sought to address whether the model is(More)
Field and laboratory studies were conducted in 2000 and 2001 to determine the feasibility of mass marking western corn rootworm adults, Diabrotica virgifera virgifera LeConte, with RbCl in the field. Results showed that application of rubidium (Rb) in solution to both the soil (1 g Rb/plant) and whorl (1 g Rb/plant) of corn plants was optimal for labeling(More)
Losses to the US insurance industry from severe weather have far outstripped rises in premiums over the past three decades, and worse could come, insurers were warned on Thursday. A study of the insurance industry and climate change by the Ceres investor group, a coalition of activist investors with an interest in environmental issues, found that there was(More)
The design, implementation and assessment of a novel, two-track, reformed introductory biology sequence are described in this paper. Course reform was based on the recommendations by the 2009 Vision & Change report from AAAS. Both tracks were based on guided inquiry, with an emphasis on constructivist pedagogy. One track included only students entering(More)
