Demographic response of northern spotted owls to barred owl removal

Creator:: Diller, Lowell V., Hamm, Keith A., Early, Desiree A., Lamphear, David W., Dugger, Katie M., Yackulic, Charles B., Schwarz, Carl J., Carlson, Peter C., and McDonald, Trent L.
Abstract:: Federally listed as threatened in 1990 primarily because of habitat loss, the northern spotted owl (Strix occidentalis caurina) has continued to decline despite conservation efforts resulting in forested habitat being reserved throughout its range. Recently, there is growing evidence the congeneric invasive barred owl (Strix varia) may be responsible for...

Staging egg development of marine copepods with DAPI and PicoGreen®

Creator:: Zirbel, Marnie Jo, Miller, Charles B., and Batchelder, Harold P.
Abstract:: Calanoid copepod eggs have a robust, chitinous outer chorion, which makes field‐collected, formaldehydefixed eggs difficult to penetrate with stains or molecular probes. Egg development studies in copepods have involved physical, chemical, and enzymatic treatments to remove the chorion. We present an efficient, one‐step method for staining copepod eggs with the...

Uncertainty analysis: an evaluation metric for synthesis science

Creator:: Harmon, Mark E., Fasth, Becky, Halpern, Charles B., and Lutz, James A.
Abstract:: The methods for conducting reductionist ecological science are well known and widely used. In contrast, those used in the synthesis of ecological science (i.e., synthesis science) are still being developed, vary widely, and often lack the rigor of reductionist approaches. This is unfortunate because the synthesis of ecological parts into...

Past tree influence and prescribed fire mediate bioticinteractions and community reassembly in agrassland-restoration experiment

Creator:: Halpern, Charles B., Antos, Joseph A., McKenzie, Donald, and Olson, Annette M.
Abstract:: Summary 1. Woody plant encroachment of grasslands is occurring globally, with profound ecological consequences. Attempts to restore herbaceous dominance may fail if the woody state is resilient or if intervention leads to an alternate, undesirable state. Restoration outcomes often hinge on biotic interactions – particularly on priority effects that inhibit...

Law Enforcement Response to “Frequent Fliers” : An Examination of High-Frequency Contacts Between Police and Justice-Involved Persons With Mental Illness

Creator:: Akins, Scott, Burkhardt, Brett C., and Lanfear, Charles
Abstract:: This article examines a subset of justice-involved persons with mental illness who have repeated contacts with law enforcement officers. Previous work has alluded to this sub-population—often termed “frequent fliers”—but little research has empirically examined its size and nature. This study proposes a method of identifying frequent fliers that is based...

In situ mobility of uranium in the presence of nitrate following sulfate-reducing conditions

Creator:: Paradis, Charles J., Jagadamma, Sindhu, Watson, David B., McKay, Larry D., Hazen, Terry C., Park, Melora, and Istok, Jonathan D.
Abstract:: Reoxidation and mobilization of previously reduced and immobilized uranium by dissolved-phase oxidants poses a significant challenge for remediating uranium-contaminated groundwater. Preferential oxidation of reduced sulfur-bearing species, as opposed to reduced uranium-bearing species, has been demonstrated to limit the mobility of uranium at the laboratory scale yet field-scale investigations are lacking....

Effect of Testosterone on Neuronal Morphology and Neuritic Growth of Fetal Lamb Hypothalamus-Preoptic Area and Cerebral Cortex in Primary Culture

Creator:: Reddy, Radhika C., Amodei, Rebecka, Estill, Charles T., Stormshak, Fred, Meaker, Mary, and Roselli, Charles E.
Abstract:: Testosterone plays an essential role in sexual differentiation of the male sheep brain. The ovine sexually dimorphic nucleus (oSDN), is 2 to 3 times larger in males than in females, and this sex difference is under the control of testosterone. The effect of testosterone on oSDN volume may result from...

Assessing the effectiveness of riparian restoration projects using Landsat and precipitation data from the cloud-computing application ClimateEngine.org

Creator:: Hausner, Mark B., Huntington, Justin L., Nash, Caroline, Morton, Charles, McEvoy, Daniel J., Pilliod, David S., Hegewisch, Katherine C., Daudert, Britta, Abatzoglou, John T., and Grant, Gordon
Abstract:: Riparian vegetation along streams provides a suite of ecosystem services in rangelands and thus is the target of restoration when degraded by over-grazing, erosion, incision, or other disturbances. Assessments of restoration effectiveness depend on defensible monitoring data, which can be both expensive and difficult to collect. We present a method...

Kinetic Prefactors of Reactions on Solid Surfaces

Creator:: Campbell, Charles T., Árnadóttir, Liney, and Sellers, Jason R. V.
Abstract:: Adsorbed molecules are involved in many reactions on solid surfaces that are of great technological importance. As such, there has been tremendous effort worldwide to learn how to theoretically predict rates for reactions involving adsorbed molecules. Theoretical calculations of rate constants require knowing both their activation energy and prefactor. Recent...
