The Need For A Common Basis For Defining Light-Use Efficiency: Implications For Productivity Estimation, Anatoly A. Gitelson, John A. Gamon

School of Natural Resources: Faculty Publications

A primary focus of this short communication is to show how the operational definition of light use efficiency (LUE) influences the results and interpretation of the LUE model. Our study was motivated by the observation that multiple LUE definitions are reported in the literature. The temporal behavior of three operational definitions of LUE, based on (i) incident radiation, (ii) total absorbed radiation and (iii) radiation absorbed by photosynthetically active/green vegetation was examined for two contrasting crops (soybean and maize) having different physiologies, leaf structures and canopy architectures. Over the course of a growing season, the behavior of these three contrasting …

Simultaneous Cr(Vi) Reduction And Methylene Blue Removal By Bacillus Sp. Jh2-2 Isolated From Mining Site Soil, Jaehong Shim, Patrick Shea, Jeong-Muk Lim, Byung-Taek Oh

School of Natural Resources: Faculty Publications

A Bacillus sp. strain (JH2-2), isolated from soil at an abandoned mine site, reduced Cr(VI) to Cr(III) under aerobic conditions. At pH 7, the strain reduced essentially all of the Cr(VI) in M9 minimal medium to Cr(III) at initial concentrations ≤50 mg Cr(VI) L⁻¹ within 100 h. The X-ray diffraction pattern of the Cr(III) precipitate matched chromium (III) hydrogen phosphate (CrH₂P₃O₁₀∙2H₂O). The JH2-2 strain showed high tolerance to other heavy metal (loid)s, with minimal inhibitory concentrations in liquid medium of (mg L−1): As (500), Cd (100), Cu (350), Ni (300), Zn …

Soil Processes Drive Seasonal Variation In Retention Of 15N Tracers In A Deciduous Forest Catchment, Christine L. Goodale, Guinevere Fredriksen, Marissa S. Weiss, Carmody K. Mccalley, Jed P. Sparks, Steven A. Thomas

School of Natural Resources: Faculty Publications

Seasonal patterns of stream nitrate concentration have long been interpreted as

demonstrating the central role of plant uptake in regulating stream nitrogen loss from forested

catchments. Soil processes are rarely considered as important drivers of these patterns. We

examined seasonal variation in N retention in a deciduous forest using three whole-ecosystem

¹⁵N tracer additions: in late April (post-snowmelt, pre-leaf-out), late July (mid-growingseason),

and late October (end of leaf-fall). We expected that plant ¹⁵N uptake would peak in

late spring and midsummer, that immobilization in surface litter and soil would peak the

following autumn leaf-fall, and that leaching losses …

A Global Perspective On Wetland Salinization: Ecological Consequences Of A Growing Threat To Freshwater Wetlands, Ellen R. Herbert, Paul Boon, Amy J. Burgin, Scott C. Neubauer, Rima B. Franklin, Marcelo Ardón, Kristine N. Hopfensperger, Leon P.M. Lamers, Peter Gell

School of Natural Resources: Faculty Publications

Salinization, a widespread threat to the structure and ecological functioning of inland and coastal wetlands, is currently occurring at an unprecedented rate and geographic scale. The causes of salinization are diverse and include alterations to freshwater flows, land-clearance, irrigation, disposal of wastewater effluent, sea level rise, storm surges, and applications of de-icing salts. Climate change and anthropogenic modifications to the hydrologic cycle are expected to further increase the extent and severity of wetland salinization. Salinization alters the fundamental physicochemical nature of the soil-water environment, increasing ionic concentrations and altering chemical equilibria and mineral solubility. Increased concentrations of solutes, especially sulfate, …

Larsson, Ty W. Matthews, Lance B. Mcnew, Michael A. Patten, Jim C. Pitman, Larkin A. Powell, Jennifer A. Smith, Tom Thompson, Donald H. Wolfe, Brett K. Sandercock

School of Natural Resources: Faculty Publications

Conservation of wildlife depends on an understanding of the interactions between animal

movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially,

but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated

patterns of space use for 10 populations of two closely related species of prairie grouse: Greater Prairie-

Chickens (Tympanuchus cupido) and Lesser Prairie-Chickens (T. pallidicinctus). Prairie chickens require large,

intact tracts of native grasslands, and are umbrella species for conservation of prairie ecosystems in North

America. We used resource utilization functions to investigate space use by female prairie chickens during …

School of Natural Resources: Faculty Publications

Interannual variability (IAV, represented by standard deviation) in net ecosystem exchange of CO₂ (NEE) is mainly driven by climatic drivers and biotic variations (i.e., the changes in photosynthetic and respiratory responses to climate), the effects of which are referred to as climatic (CE) and biotic effects (BE), respectively. Evaluating the relative contributions of CE and BE to the IAV in carbon (C) fluxes and understanding their controlling mechanisms are critical in projecting ecosystem changes in the future climate. In this study, we applied statistical methods with flux data from 65 sites located in the Northern Hemisphere to address this …

Comparison Of Four Evi-Based Models For Estimating Gross Primary Production Of Maize And Soybean Croplands And Tallgrass Prairie Under Severe Drought, Jinwei Dong, Xiangming Xiao, Pradeep Wagle, Geli Zhang, Yuting Zhou, Cui Jin, Margaret S. Torn, Tilden P. Meyers, Andrew E. Suyker, Junbang Wang, Huimin Yan, Chandrashekhar Biradar, Berrien Moore Iii

School of Natural Resources: Faculty Publications

Accurate estimation of gross primary production (GPP) is critical for understanding ecosystem response to climate variability and change. Satellite-based diagnostic models, which use satellite images and/or climate data as input, are widely used to estimate GPP. Many models used the Normalized Difference Vegetation Index (NDVI) to estimate the fraction of absorbed photosynthetically active radiation (PAR) by vegetation canopy (FPAR_canopy) and GPP. Recently, the Enhanced Vegetation Index (EVI) has been increasingly used to estimate the fraction of PAR absorbed by chlorophyll (FPAR_chl) or green leaves (FPAR_green) and to provide more accurate estimates of GPP in …

Estimation And Analysis Of Gross Primary Production Of Soybean Under Various Management Practices And Drought Conditions, Pradeep Wagle, Xiangming Xiao, Andrew E. Suyker

School of Natural Resources: Faculty Publications

Gross primary production (GPP) of croplands may be used to quantify crop productivity and evaluate a range of management practices. Eddy flux data from three soybean (Glycine max L.) fields under different management practices (no-till vs. till; rainfed vs. irrigated) and Moderate Resolution Imaging Spectroradiometer (MODIS) derived vegetation indices (VIs) were used to test the capabilities of remotely sensed VIs and soybean phenology to estimate the seasonal dynamics of carbon fluxes. The modeled GPP (GPP_VPM) using vegetation photosynthesis model (VPM) was compared with the GPP (GPP_EC) estimated from eddy covariance measurements. The VIs tracked soybean …

Significant climate risks are associated with a positive carbon–temperature feedback in northern latitude carbon-rich ecosystems,making an accurate analysis of human impacts on the net greenhouse gas balance of wetlands a priority. Here, we provide a coherent assessment of the climate footprint of a network of wetland sites based on simultaneous and quasi-continuous ecosystem observations of CO₂ and CH₄ fluxes. Experimental areas are located both in natural and in managed wetlands and cover a wide range of climatic regions, ecosystem types, and management practices. Based on direct observations we predict that sustained CH₄ emissions in natural ecosystems are …

Modeling Actual Evapotranspiration With Routine Meteorological Variables In The Data-Scarce Region Of The Tibetan Plateau: Comparisons And Implications, Ning Ma, Yinsheng Zhang, Chong-Yu Xu, Jozsef Szilagyi

School of Natural Resources: Faculty Publications

Quantitative estimation of actual evapotranspiration (ET_a) by in situ measurements and mathematical modeling is a fundamental task for physical understanding of ETa as well as the feedback mechanisms between land and the ambient atmosphere. However, the ETa information in the Tibetan Plateau (TP) has been greatly impeded by the extremely sparse ground observation network in the region. Approaches for estimating ET_a solely from routine meteorological variables are therefore important for investigating spatiotemporal variations of ETa in the data-scarce region of the TP. Motivated by this need, the complementary relationship (CR) and Penman-Monteith approaches were evaluated against in …

Complementary-Relationship-Based 30 Year Normals (1981–2010) Of Monthly Latent Heat Fluxes Across The Contiguous United States, Jozsef Szilagyi

School of Natural Resources: Faculty Publications

Thirty year normal (1981–2010) monthly latent heat fluxes (ET) over the conterminous United States were estimated by a modified Advection-Aridity model from North American Regional Reanalysis (NARR) radiation and wind as well as Parameter-Elevation Regressions on Independent Slopes Model (PRISM) air and dew-point temperature data. Mean annual ET values were calibrated with PRISM precipitation (P) and validated against United States Geological Survey runoff (Q) data. At the six-digit Hydrologic Unit Code level (sample size of 334) the estimated 30 year normal runoff (P – ET) had a bias of 18 mm yr^-1, a root-mean-square error of …

Atmospheric Circulation Processes Contributing To A Multidecadal Variation In Reconstructed And Modeled Indian Monsoon Precipitation, Qianru Wu, Qi Hu

School of Natural Resources: Faculty Publications

An analysis of the recently reconstructed gridded May–September total precipitation in the Indian monsoon region for the past half millennium discloses significant variations at multidecadal timescales. Meanwhile, paleo-climate modeling outputs from the National Center for Atmospheric Research Community Climate System Model 4.0 show similar multidecadal variations in the monsoon precipitation. One of those variations at the frequency of 40–50 years per cycle is examined in this study. Major results show that this variation is a product of the processes in that the meridional gradient of the atmospheric enthalpy is strengthened by radiation loss in the high-latitude and polar region. Driven …

Kermit Gosnell’S Babies: Abortion, Infanticide And Looking Beyond The Masks Of The Law, Richard F. Duncan

Nebraska College of Law: Faculty Publications

If, as Laurence Tribe has observed, “all law tells a story,” this Article tells two stories occurring forty years apart—the story of Justice Harry Blackmun and the unborn human beings he covered with the legal mask of “potential” lives in Roe v. Wade in 1973, and the story of Doctor Kermit Gosnell and the unmasked babies he was convicted of murdering in his Philadelphia abortion clinic in 2013. As Professor Tribe also observes, these stories amount to “a clash of absolutes, of life against liberty,” and therefore they are stories that must be told time and again, until we get …

Bio-Oil And Biodiesel As Biofuels Derived From Microalgal Oil And Their Characterization By Using Instrumental Techniques, Dipesh Kumar, Bhaskar Singh, Kuldeep Bauddh, John Korstad

College of Science and Engineering Faculty Research and Scholarship

Microalgal oil has been a source for production of biofuels such as bio-oil and biodiesel. These two biofuels can be characterized quantitatively using advanced instrumentation techniques. Nile red fluorescence method, PAM fluorometry, NMR, GC/GC-MS, and FTIR are among the major techniques available for characterization and quantification of algal oil. NMR is a rapid and nondestructive analytical technique as it requires minimal sample preparation, and even one intact algal cell can be analyzed. It can also be used for continuous monitoring of cellular composition of algal culture. NMR can be used to monitor transesterification reaction and oxidation of lipids and biodiesel …

Mathematics: A Good Predictor For Success In A Health Science Degree, G Hine, R Anderton, C Joyce

Avoiding Unnecessary Divorce And Restoring Justice In Marital Separations - Review Of Family Law Act 1975 (Fla), Christopher Brohier, Nigel K. Zimmermann

Law Papers and Journal Articles

The concept of no-fault divorce which became law in Australia in 1975 was part of a revolution in divorce law reform which swept through the western world in the late 1960s and 1970s. It was predicated on a notion that the law should aim to buttress marriage, but if the marriage was finished in fact, the law should “enable the empty legal shell to be destroyed with the maximum fairness, and minimum bitterness, distress and humiliation.” Property would be divided on a “once for all” basis, the children, though not physically divided, would be apportioned between a “custodial” parent and …

Hypocalcemia-Induced Seizure: Demystifying The Calcium Paradox, Pengcheng Han, Bradley J. Trinidad, Jiong Shi

Neurology

Calcium is essential for both neurotransmitter release and muscle contraction. Given these important physiological processes, it seems reasonable to assume that hypocalcemia may lead to reduced neuromuscular excitability. Counterintuitively, however, clinical observation has frequently documented hypocalcemia€™s role in induction of seizures and general excitability processes such as tetany, Chvostek€™s sign, and bronchospasm. The mechanism of this calcium paradox remains elusive, and very few pathophysiological studies have addressed this conundrum. Nevertheless, several studies primarily addressing other biophysical issues have provided some clues. In this review, we analyze the data of these studies and propose an integrative model to explain this hypocalcemic …

Increased High-Density Lipoprotein Cholesterol Levels In Mice With Xx Versus Xy Sex Chromosomes, Jenny C. Link, Xuqi Chen, Christopher Prien, Mark S. Borja, Bradley Hammerson, Michael N. Oda, Arthur P. Arnold, Karen Reue

Biology

Objective—

The molecular mechanisms underlying sex differences in dyslipidemia are poorly understood. We aimed to distinguish genetic and hormonal regulators of sex differences in plasma lipid levels.

Approach and Results—

We assessed the role of gonadal hormones and sex chromosome complement on lipid levels using the four core genotypes mouse model (XX females, XX males, XY females, and XY males). In gonadally intact mice fed a chow diet, lipid levels were influenced by both male–female gonadal sex and XX–XY chromosome complement. Gonadectomy of adult mice revealed that the male–female differences are dependent on acute effects of gonadal hormones. In both …

Milledgeville Audubon Society Collection (1930-1968), Georgia College And State University

Special Collections Finding Aids

The minutes of the meetings of the Milledgeville Audubon Society range from its inception in 1930 through November of 1968. The society first met at the Baptist Church on December 8, 1930 with 8 members. At the 2nd meeting on January 5, 1931, the "Constitution" was presented and adopted. In the beginning, it was also called the "Bird Club." The main purpose at the onset of the society was for the protection of migratory birds, and teaching young people about the preservation of birdlife. The M.A.S. was a member of the Georgia and National Ornithological Societies.
