Southeast Asia (SEA) hosts one of the most complex aerosol systems in the world, with convoluted meteorological scales, sharp geographic and socioeconomic features, high biological productivity, mixtures of a wide range of atmospheric pollutants, and likely a significant susceptibility to global climate change. This physical complexity of SEA is coupled with one of the world's most challenging environments for both in situ and remote sensing observation. The 7-Southeast Asian Studies (7SEAS) program was formed to facilitate interdisciplinary research into the integrated SEA aerosol environment via grass roots style collaboration. In support of the early 7SEAS program and the affiliated Southeast …

Maximizing A New Quantity In Sequential Reserve Selection, Adam W. Schapaugh, Andrew J. Tyre

School of Natural Resources: Faculty Publications

The fundamental goal of conservation planning is biodiversity persistence, yet most reserve selection methods prioritize sites using occurrence data. Numerous empirical studies support the notion that defining and measuring objectives in terms of species richness (where the value of a site is equal to the number of species it contains, or contributes to an existing reserve network) can be inadequate for maintaining biodiversity in the long term. An existing site-assessment framework that implicitly maximized the persistence probability of multiple species was integrated with a dynamic optimization model. The problem of sequential reserve selection as a Markov decision process was combined …

Spatial And Temporal Unpredictability Of Colony Size In Cliff Swallows Across 30 Years, Charles R. Brown, Mary Bomberger Brown, Erin A. Roche

School of Natural Resources: Faculty Publications

Most colonially breeding animals occupy colonies that range in size from a few pairs to thousands of individuals, but the causes of colony size variation are largely unknown. Three general hypotheses are: (1) that variation in colony size is maintained by fluctuating selection via spatial and temporal changes in fitness associated with different colony sizes; (2) that colony formation reflects heterogeneity in habitat, with some sites having resources to support more individuals than others; and (3) that individuals assess the presence or annual reproductive success of current colony residents at each site and aggregate preferentially at high-quality sites. These hypotheses …

Potential Water Quality Impacts Originating From Land Burial Of Cattle Carcasses, Qi Yuan, Daniel D. Snow, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

Among the conventional disposal methods for livestock mortalities, on‐farm burial is a preferred method, but the potential water quality impacts of animal carcass burial is not well understood. Typically, on‐farm burial pits are constructed without liners to prevent percolation of leachate into soil and groundwater. To date, no information is available on temporal trends for contaminants in leachate produced from livestock mortality pits. In our study, we examined the concentrations of conventional contaminants (electrical conductivity, COD, TOC, TKN, TP, and solids) as well as some antimicrobials and steroid hormones for a period of 20 months. High concentrations of conventional contaminants …

The Relative Importance Of Exogenous And Substrate-Derived Nitrogen For Microbial Growth During Leaf Decomposition, B. M. Cheever, J. R. Webster, E. E. Bilger, S. A. Thomas

School of Natural Resources: Faculty Publications

Heterotrophic microbes colonizing detritus obtain nitrogen (N) for growth by assimilating N from their substrate or immobilizing exogenous inorganic N. Microbial use of these two pools has different implications for N cycling and organic matter decomposition in the face of the global increase in biologically available N. We used sugar maple leaves labeled with ¹⁵N to differentiate between microbial N that had been assimilated from the leaf substrate (enriched with ¹⁵N) or immobilized from the water (natural abundance ¹⁵N:¹⁴N) in five Appalachian streams ranging in ambient NO₃-N concentrations from about 5 to 900 …

Surface Energy Balance Model Of Transpiration From Variable Canopy Cover And Evaporation From Residue-Covered Or Bare Soil Systems: Model Evaluation, Luis Octavio Lagos, Derrel Martin, Shashi B. Verma, Suat Irmak, Ayse Kilic, Dean E. Eisenhauer, Andrew E. Suyker

School of Natural Resources: Faculty Publications

A surface energy balance model (SEB) was extended by Lagos et al. Irrig Sci 28:51–64 (2009) to estimate evapotranspiration (ET) from variable canopy cover and evaporation from residue-covered or bare soil systems. The model estimates latent, sensible, and soil heat fluxes and provides a method to partition evapotranspiration into soil/residue evaporation and plant transpiration. The objective of this work was to perform a sensitivity analysis of model parameters and evaluate the performance of the proposed model to estimate ET during the growing and non-growing season of maize (Zea Mays L.) and soybeans (Glycine max) in eastern …

Historic Changes (1941–2008) In Side Channel And Backwater Habitats On An Unchannelized Reach Of The Missouri River, L. A. Yager, M. D. Dixon, T. C. Cowman, D. A. Soluk

United States National Park Service: Publications

Flow regulation has had pervasive effects on aquatic ecosystems within the world’s large rivers. While channelization on the lower Missouri River has led to major changes in the river and its floodplain, including the loss of shallow water habitats, effects of upstream dams on unchannelized reaches on the Missouri have not been formally assessed. We quantified changes in the number and size of off-channel habitats, specifically backwaters and side channels, on the 95-km unchannelized reach of the Missouri below Gavins Point Dam (Yankton, South Dakota) using historical (1941, 1983–1985, 2008) aerial imagery. Total and mean areas of side channels declined …

Mobilization After Repression: Reconsidering The Role Of Testimonies And Exiles In Post-War El Salvador, Angela Elena Fillingim

Societies Without Borders

During the civil war in El Salvador, the Salvadoran military engaged in the systematic disappearance of youth and facilitated their adoptions. Presently Found, a Salvadoran human rights NGO, works to reunite these youth with their surviving biological families. However, a key difference between Found and other similar organizations, is that the former was established in the post-war context. Through a case study of Found, and placed in comparative light with a similar phenomenon in Argentina, I will show that traditional mobilization strategies face new obstacles in a post-war context. Specifically, while Found engaged in many of the same movement tactics …

Treading Water While Congress Ignores The Nation’S Environment, Sandra Zellmer

Nebraska College of Law: Faculty Publications

During the late 1960s, the nation’s attention was riveted on graphic images of contaminated resources, such as smoldering rivers and oil-soaked seagulls, as well as Rachel Carson’s haunting prose about the “strange blight” of chemical pesticides afflicting land, water, and wildlife. Policymakers recognized the need for strong legal protections for public health and the environment, and Congress responded with sweeping legislation governing the pollution of water, air, and soil, and the demise of threatened and endangered species.

The Clean Water Act of 1972 (CWA), which regulates discharges of pollutants into waters of the United States, is one of the most …

Assessing Institutional Ability To Support Adaptive, Integrated Water Resources Management, Christina Hoffman, Sandra Zellmer

Nebraska College of Law: Faculty Publications

At a time when many, if not all, western states are under pressure to redefine how water resources are managed, this Article provides insight into how one state—Nebraska—has attempted to modify the water management institutions within its borders to implement more integrated management approaches that embrace flexibility and adaptability. Nebraska is a state that has extensive surface and groundwater development and different legal systems and management agencies for governing surface and groundwater resources. This late in the game, the state is unlikely to assimilate governance of surface and groundwater resources into a single, overarching legal system. Instead, Nebraska has adopted …

Improving Water Quality Antidegradation Policies, Sandi Zellmer, Robert L. Glicksman

Nebraska College of Law: Faculty Publications

This Article focuses on the Clean Water Act’s relatively neglected maintenance aspects. It assesses whether the statute’s antidegradation policy for protecting superior water quality has fostered the statutory maintenance goal. Part I traces the history of the antidegradation policy and analyzes the rationales for precluding the degradation of high-quality environmental resources. The objectives of, and justifications for, preventing the deterioration of high-quality resources are best illustrated by comparing the antidegradation program adopted under the CWA with the version adopted under the Clean Air Act (“CAA”), which is the most elaborate antidegradation program in domestic federal pollution control legislation. Part II …

Posterior Reversible Encephalopathy Syndrome, Courtney M. Schusse, Alicia L. Peterson, Jason P. Caplan

Neurology

Background: The presentation of posterior reversible encephalopathy syndrome (PRES) features neuropsychiatric symptoms in the context of predominantly white matter cerebral edema in the setting of a diverse variety of underlying clinical entities. Objective: To illustrate the presentation and diagnostic strategy for this under-recognized condition. Method: We present two cases of PRES and review the available literature. Results: PRES may be due to a number of underlying conditions, but typically presents with symptoms consistent with delirium. Conclusions: Psychiatrist practicing in the general hospital should be aware of the presentation and appropriate work-up of PRES to forestall serious potential sequelae.

Metabolic Impact Of Sex Chromosomes, Jenny Link, Xuqi Chen, Arthur P. Arnold, Karen Reue

Biology

Obesity and associated metabolic diseases are sexually dimorphic. To provide better diagnosis and treatment for both sexes, it is of interest to identify the factors that underlie male/female differences in obesity. Traditionally, sexual dimorphism has been attributed to effects of gonadal hormones, which influence numerous metabolic processes. However, the XX/XY sex chromosome complement is an additional factor that may play a role. Recent data using the four core genotypes mouse model have revealed that sex chromosome complement—independently from gonadal sex—plays a role in adiposity, feeding behavior, fatty liver and glucose homeostasis. Potential mechanisms for the effects of sex chromosome complement …

Rod Monochromacy And The Coevolution Of Cetacen Retinal Opsins, Christopher A. Emerling, Robert W. Meredith, John Gatesy, Vincent M. York, Mark S. Springer

Biology

Cetaceans have a long history of commitment to a fully aquatic lifestyle that extends back to the Eocene. Extant species have evolved a spectacular array of adaptations in conjunction with their deployment into a diverse array of aquatic habitats. Sensory systems are among those that have experienced radical transformations in the evolutionary history of this clade. In the case of vision, previous studies have demonstrated important changes in the genes encoding rod opsin (RH1), short-wavelength sensitive opsin 1 (SWS1), and long-wavelength sensitive opsin (LWS) in selected cetaceans, but have not examined the full complement of opsin genes across the complete …

Functional Assessment Of Pharmacological Telomerase Activators In Human T Cells, Hector F. Valenzuela, Brenda Molgara, Riley Bateman, Greg Sweeney, Danielle Finger, Taylor Dimler, Rita B. Effros

Biology

Telomeres are structures at the ends of chromosomes that shorten during cell division and eventually signal an irreversible state of growth arrest known as cellular senescence. To delay this cellular aging, human T cells, which are critical in the immune control over infections and cancer, activate the enzyme telomerase, which binds and extends the telomeres. Several different extracts from the Astragalus membranaceus root have been documented to activate telomerase activity in human T cells. The objective of this research was to compare two extracts from Astragalus membranaceus, TA-65 and HTA, for their effects on both telomerase and proliferative activity of …
