A methodology to generate spatially continuous fields of tree heights with an optimized Allometric Scaling and Resource Limitations (ASRL) model is reported in this first of a multi-part series of articles. Model optimization is performed with the Geoscience Laser Altimeter System (GLAS) waveform data. This methodology is demonstrated by mapping tree heights over forested lands in the continental USA (CONUS) at 1 km spatial resolution. The study area is divided into 841 eco-climatic zones based on three forest types, annual total precipitation classes (30 mm intervals) and annual average temperature classes (2 °C intervals). Three model parameters (area of single …

Intense selective pressures applied over short evolutionary time have resulted in homogeneity within, but substantial variation among, horse breeds. Utilizing this population structure, 744 individuals from 33 breeds, and a 54,000 SNP genotyping array, breed-specific targets of selection were identified using an F(ST)-based statistic calculated in 500-kb windows across the genome. A 5.5-Mb region of ECA18, in which the myostatin (MSTN) gene was centered, contained the highest signature of selection in both the Paint and Quarter Horse. Gene sequencing and histological analysis of gluteal muscle biopsies showed a promoter variant and intronic SNP of MSTN were each significantly associated with …

Biogenic Nitrogen Gas Production At The Oxic–Anoxic Interface In The Cariaco Basin, Venezuela, E. Montes, M. A. Altabet, F. E. Muller-Karger, M. I. Scranton, R. C. Thunell, Claudia R. Benitez-Nelson, L. Lorenzoni, Y. M. Astor

Faculty Publications

Excess nitrogen gas (N2xs) was measured in samples collected at six locations in the eastern and western sub-basins of the Cariaco Basin, Venezuela, in September 2008 (non-upwelling conditions) and March 2009 (upwelling conditions). During both sampling periods, N2xs concentrations were below detection in surface waters, increasing to ~ 22 μmol N kg−1 at the oxic–anoxic interface ([O2] < ~ 4 μmol kg−1, ~ 250 m). Below the oxic–anoxic interface (300–400 m), the average concentration of N2xs was 24.7 ± 1.9 μmol N kg−1 in September 2008 and 27.5 ± 2.0 μmol N kg−1 in March 2009, i.e., N2xs concentrations within this depth interval were ~ 3 μmol N kg−1 higher (p < 0.001) during the upwelling season compared to the non-upwelling period. These results suggest that N-loss in the Cariaco Basin may vary seasonally in response to changes in the flux of sinking particulate organic matter. We attribute the increase in N2xs concentrations, or N-loss, observed during upwelling to: (1) higher availability of fixed nitrogen derived from suspended and sinking particles at the oxic–anoxic interface and/or (2) enhanced ventilation at the oxic–anoxic interface during upwelling.

The Mighty Work Of Making Nations Happy: A Response To James Davison Hunter, Patrick Mckinley Brennan

Pepperdine Law Review

This article is an invited response to James Davison Hunter’s much-discussed book To Change the World: The Irony, Tragedy, and Possibility of Christianity in the Late Modern World (Oxford University Press, 2010). Hunter, a sociologist at UVA and a believing Protestant, claims that law’s capacity to contribute to social change is “mostly illusory” and that Christians, therefore, should practice “faithful presence” in the public square rather than seek to influence law directly. My response is that it is, in fact, law’s stunning ability to alter and limit available choices that makes it an object of deservedly fierce contest. The wild …

Dictyostelium Development Shows A Novel Pattern Of Evolutionary Conservation, Xiangjun Tian, Joan E. Strassmann, David C. Queller

Biology Faculty Research

von Baer's law states that early stages of animal development are the most conserved. More recent evidence supports a modified "hourglass" pattern in which an early but somewhat later stage is most conserved. Both patterns have been explained by the relative complexity of either temporal or spatial interactions; the greatest conservation and lowest evolvability occur at the time of the most complex interactions, because these cause larger effects that are harder for selection to alter. This general kind of explanation might apply universally across independent multicellular systems, as supported by the recent finding of the hourglass pattern in plants. We …

Projectile And Target Scaling Of The Total Ionization Cross Sections Of Atoms And Molecules, E. C. Montenegro, G. M. Sigaud, Robert D. Dubois

Physics Faculty Research & Creative Works

A scaling for the total ionization cross sections of atomic and molecular targets by neutral to highly charged projectiles with energies ranging from a few keV/u to many MeV/u is presented, with few free parameters, all velocity independent, and whose values do not vary appreciably for the projectiles and atomic and molecular targets considered here. Another important feature of the proposed scaling is that it has been built considering the characteristics of the collision systems, taking into account the various physical processes that lead to target ionization and the velocity regions where each of them dominates, and performing a smooth …

ABSTRACT: BACKGROUND: There is scant data regarding disease presentation and treatment response among black men living in Africa. In this study we evaluate disease presentation and early clinical outcomes among Ghanaian men with prostate cancer treated with external beam radiotherapy (EBRT). METHODS: A total of 379 men with prostate cancer were referred to the National Center for Radiotherapy, Ghana from 2003 to 2009. Data were collected regarding patient-and tumor-related factors such as age, prostate specific antigen (PSA), Gleason score (GS), clinical stage (T), and use of androgen deprivation therapy (ADT). For patients who received EBRT, freedom from biochemical failure (FFbF) …

Climate Vulnerability And Adaptive Strategies Along The Rio Grande/Rio Bravo Border Of Mexico And The United States, Brian Hurd

Journal of Contemporary Water Research and Education

Climate change and growing populations are dual stresses that are particularly challenging to communities along the US/Mexican border where adaptive capacity is limited, infrastructure is lacking, and economic resources are scarce. Although regional precipitation projections vary significantly in both timing and amount, projections of temperature changes produce a more robust signal of raised temperatures. A summary look is provided that highlights the climatic changes that are projected, identifies key systems and sectors that are vulnerable to climate change, describes and summarizes the role of adaptation and the development of adaptation strategies. A promising look at binational co-adaptation is highlighted and …

The Past, Present, And Future Of Water Conflict And International Security, David K. Kreamer

Journal of Contemporary Water Research and Education

Water stress and scarcity has affected, and will continue to affect, the stability of communities. An overview of global water security challenges indicates profound difficulties and potential flashpoints. There are many examples of struggles in supplying clean water throughout the world, and how water has been both a strategic tool and object of conflict in the past. Water has been an instrument of ethnic and religious conflict, and has recently been used in regional and local clashes. Transboundary water disputes are also potentially dangerous in several regions of the world and stresses from climate change and variability increase the uncertainty …

Preconditioning Induces Sustained Neuroprotection By Down Regulation Of Ampk, Louise D. Mccullough, Venugopal Reddy Venna, Jun Li, Sharon E. Benashski, Sami Tarabishy

UCHC Articles - Research

Abstract Background and Purpose—Ischemic preconditioning (IPC) induces endogenous neuroprotection from a subsequent ischemic injury. IPC involves down-regulation of metabolic pathways. As Adenosine 5′-monophosphate-activated protein kinase (AMPK) is a critical sensor of energy balance and plays a major role in cellular metabolism, its role in IPC was investigated.

Methods—A brief 3 minute middle cerebral artery occlusion (MCAO) was employed to induce IPC in male mice 72 hours prior to 90 minute MCAO. Levels of AMPK and pAMPK, the active form of the kinase, were assessed after IPC. A pharmacological activator or inhibitor of AMPK was utilized to determine the …

Prioritizing Pacific Salmon Stocks For Conservation: Response To Allendorf Et Al., Thomas C. Wainwright, Robin Waples

United States Department of Commerce: Staff Publications

Recently, Allendorf et al. (1997) proposed criteria intended to guide prioritization of Pacific salmon (Oncorhynchus spp.) stocks for conservation. The authors provide a good summary of several important aspects of extinction risk, and we agree with many of their points: (1) prioritization is useful and may help focus conservation efforts; (2) a two-pronged approach that identifies the relative risk faced by different populations and evaluates their significance is a reasonable strategy; (3) risks should be evaluated based on multiple criteria; and (4) specific threshold values for these criteria promote objectivity and can assist in decision making. We also recognize …
