Nebraska Bird Review

This was not a spectacular fall by most measures, but, as usual, there was much to chew on. Continuing the trend seen in recent falls, lingering has become the norm; this phenomenon is across the board, involving, for example, Baird’s Sandpiper, Greater Yellowlegs, Mourning Dove, American White Pelican, Barn Owl, Lesser Goldfinch, several native sparrow species, Palm and Orange-crowned Warblers, and even rearof- the-order Dickcissel. Apparent range expansion is occurring with Red-shouldered Hawk and Barred Owl, the former northward and the latter westward. A couple of taxonomic notes relate to the subspecies Buteo jamaicensis abieticola of Red-tailed Hawk and subspecies …

The Positive Role Of Curcumin-Loaded Salmon Nanoliposomes On The Culture Of Primary Cortical Neurons, Mahmoud Hasan, Shahrzad Latifi, Cyril J.F. Kahn, Ali Tamayol, Rouhollah Habibey, Elodie Passeri, Michel Linder, Elmira Arab-Tehrany

Department of Mechanical and Materials Engineering: Faculty Publications

Curcumin (diferuloylmethane) is a natural bioactive compound with many health-promoting benefits. However, its poor water solubility and bioavailability has limited curcumin’s biomedical application. In the present study, we encapsulated curcumin into liposomes, formed from natural sources (salmon lecithin), and characterized its encapsulation efficiency and release profile. The proposed natural carriers increased the solubility and the bioavailability of curcumin. In addition, various physico-chemical properties of the developed soft nanocarriers with and without curcumin were studied. Nanoliposome-encapsulated curcumin increased the viability and network formation in the culture of primary cortical neurons and decreased the rate of apoptosis.

Considerations For The 2019–2021 Nisc Management Plan, Invasive Species Advisory Committee

National Invasive Species Council

The Issue

Efforts to prevent the importation of invasive species are insufficient to protect the United States. Nor are resources adequate for the eradication or control of invasive species that have already entered the country. There is a clear need for more effective coordination and collaboration among federal agencies and other entities to address gaps and inconsistencies in relevant statutes, regulations, agency authorities, as well as to improve and sustain access to the data needed to inform decisions and direct action

Landscapes From The Waves—Marine Terraces Of California, Marjorie Schulz, Corey Lawrence, Daniel R. Muhs, Carol Prentice, Sam Flanagan

United States Geological Survey: Publications

M any coastlines around the world have stair-step landforms, known as marine terraces. Marine terraces make up a large part of coastal California’s landscape—from San Diego to Crescent City. Find out how these landscapes form, why marine terraces are of interest to scientists, and where you can explore these landscapes.

Marine terraces result from the interaction of two geologic processes: uplift of the land surface and the natural rise and fall of sea level over hundreds of thousands of years. As sea level rises, waves move underwater sediment—sand and gravel—back and forth against bedrock, acting like sandpaper to hone bedrock …

2017-2018 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were held during the 2017-18 Christmas Bird Count season, which is one more than has ever been done in the past. Although the Crawford count was not done this season, the new Lower Platte River count, centered at the junction of Platteview Road and 204th St. south of Gretna, was added. A total 236 observers took part in at least one count, 26 did two counts, four did three counts, five did four counts and four persons did six counts. However, special recognition goes to Gary Roberts, who did eight counts this season. I am not aware of …

Fossils On The Floor In The Nebraska State Capitol: A Coloring And Activities Book, Robert F. Diffendal Jr.

Conservation and Survey Division: Faculty and Staff Publications

The Nebraska State Capitol is a wonderful place. This building is home to great treasures of art owned by the people of Nebraska. The floor of the Capitol Rotunda has beautiful works of art. Maybe you have seen this art. Small pieces of two kinds of rocks make pictures of people, their tools, the natural resources they used, and pictures of fossil animals and plants. These kinds of pictures are called mosaics [moe ZAY icks]. The animals and plants follow one another in a curved ribbon around the floor. In that ribbon of pictures are many kinds of fossil animals …

Livestock Air Emission Requirements Delayed For Now, J. David Aiken

Cornhusker Economics

Summary. Federal environmental laws require the reporting of emergency releases of hazardous substances to federal, state and local emergency res-ponders. EPA has established a 2008 reporting exemption for livestock operations smaller than large concentrated animal feeding operations (CAFOs). Environmental groups challenged the EPA livestock exemption. On April 11, 2017, the D. C. Court of Appeals invalidated the EPA livestock reporting exemption. Reporting requirements briefly went into effect November 15, 2017 but have now been postponed until May 1, 2018.

Reducing Dietary Protein In Pond Production Of Hybrid Striped Bass (Morone Chrysops × M. Saxatilis): Effects On Fish Performance And Water Quality Dynamics, Steven Rawles, Bartholomew Green, Matthew Mcentire, T. Gibson Gaylord, Frederic T. Barrows

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In previous work, we demonstrated that diets containing 40% digestible protein (DP) (45% crude protein) and 18% lipid supplemented with Met and Lys resulted in superior performance and nutrient retentions in hybrid striped bass (HSB) compared to less energy-dense diets when rearing HSB at temperatures similar to the summer growing period of the Southern U.S. The current work was aimed at vetting previous results in pond production of market-size HSB at commercial stocking densities to assess impacts on fish production indices and water quality parameters. Diets were formulated to contain digestible protein levels ranging from 41% to 35% DP and …

Sarcocystis Cymruensis: Discovery In Western Hemisphere In The Brown Rat (Rattus Norvegicus) From Grenada, West Indies: Redescription, Molecular Characterization, And Transmission To Ifn-Γ Gene Knockout Mice Via Sporocysts From Experimentally Infected Domestic Cat (Felis Catus), Fernando H. Antunes Murata, Camila K. Cerqueira-Cézar, Peter C. Thompson, Keshaw Tiwari, Joseph D. Mowery, Shiv K. Verma, Benjamin M. Rosenthal, Ravindra N. Sharma, J. P. Dubey

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Rodents are intermediate hosts for many species of Sarcocystis. Little is known of Sarcocystis cymruensis that uses the Brown rat (Rattus norvegicus) as intermediate hosts and the domestic cat (Felis catus) as experimental definitive host. Here, we identified and described Sarcocystis cymruensis in naturally infected R. norvegicus from Grenada, West Indies. Rats (n = 167) were trapped in various locations in two parishes (St. George and St. David). Microscopic, thin (< 1 μm) walled, slender sarcocysts were found in 11 of 156 (7.0%) rats skeletal muscles by squash examination. A laboratory-raised cat fed naturally infected rat tissues excreted sporocysts that were infectious for interferon gamma gene knockout (KO) mice, but not to Swiss Webster outbred albino mice. All inoculated mice remained asymptomatic, and microscopic S. cymruensis-like sarcocysts were found in the muscles of KO mice euthanized on day 70, 116, and 189 post inoculation (p.i.). Sarcocysts from infected KO mice were infective for cats at day 116 but not at 70 days p.i. By transmission electron microscopy, the sarcocyst wall was Btype 1a.^ Detailed morphological description of the cyst wall, metrocytes, and bradyzoites is given for the first time. Additionally, molecular data on S. cymruensis are presented also for the first time. Molecular characterization of sarcocysts 18S rDNA and 28S rDNA, ITS-1, and cox1 loci showed the highest similarity with S. rodentifelis and S. muris. In conclusion, the present study described the natural infection of S. cymruensis in Brown rat for the first time in a Caribbean country and provided its molecular characteristics.

United States Navy: Publications

Little is known about microsporidiosis pathogenicity in cetaceans. Here we report seroprevalence of 76% for microsporidia in blood samples from common bottlenose dolphins (Tursiops truncatus), from animals managed under human care (n=108) or captured for health assessments (n=13) and released.

Gamma Irradiation Inactivates Honey Bee Fungal, Microsporidian, And Viral Pathogens And Parasites, Michael Simone-Finstrom, Kate Aronstein, Michael Goblirsch, Frank Rinkevich, Lilia De Guzman

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Managed honey bee (Apis mellifera) populations are currently facing unsustainable losses due to a variety of factors. Colonies are challenged with brood pathogens, such as the fungal agent of chalkbrood disease, the microsporidian gut parasite Nosema spp., and several viruses. These pathogens may be transmitted horizontally from worker to worker, vertically from queen to egg and via vectors like the parasitic mite, Varroa destructor. Despite the fact that these pathogens are widespread and often harbored in wax comb that is reused from year to year and transferred across beekeeping operations, few, if any, universal treatments exist for their control. In …

The Copyright Permissions Culture In Software Preservation And Its Implications For The Cultural Record, Patricia Aufderheide, Brandon Butler, Krista Cox, Peter Jaszi

Copyright, Fair Use, Scholarly Communication, etc.

This report summarizes results from research with the professionals who make up the software preservation community about how their understanding of copyright intersects with their preservation mission. Professionals typically face significant challenges from perceived copyright barriers. They tend to assume that a license or other express permission from a copyright holder is required before embarking on a wide variety of preservation activities, and typically find that such permissions are difficult or impossible to obtain. In the absence of reliable information to guide informed risk assessment, professionals act on the reasonable assumption that high levels of legal risk could be associated …

Factors Influencing Farmers’ Adoption Of Best Management Practices: A Review And Synthesis, Tingting Liu, Randall J. F. Bruins, Matthew T. Heberling

National Drought Mitigation Center: Faculty Publications

Best management practices (BMPs) for reducing agricultural non-point source pollution are widely available. However, agriculture remains a major global contributor to degradation of waters because farmers often do not adopt BMPs. To improve water quality, it is necessary to understand the factors that influence BMP adoption by farmers. We review the findings of BMP adoption studies from both developed and developing countries, published after (or otherwise not included in) two major literature reviews from 2007 and 2008. We summarize the study locations, scales, and BMPs studied; the analytical methods used; the factors evaluated; and the directionality of each factor’s influence …

Early Tcr Signaling Induces Rapid Aerobic Glycolysis Enabling Distinct Acute T Cell Effector Functions, Ashley V. Menk, Nicole E. Scharping, Rebecca S. Moreci, Xue Zeng, Cliff Guy, Sonia Salvatore, Heekyong Bae, Jianxin Xie, Howard A. Young, Stacy Gelhaus Wendell, Greg M. Delgoffe

United States Public Health Resources

To fulfill bioenergetic demands of activation, T cells perform aerobic glycolysis, a process common to highly proliferative cells in which glucose is fermented into lactate rather than oxidized in mitochondria. However, the signaling events that initiate aerobic glycolysis in T cells remain unclear. We show T cell activation rapidly induces glycolysis independent of transcription, translation, CD28, and Akt and not involving increased glucose uptake or activity of glycolytic enzymes. Rather, TCR signaling promotes activation of pyruvate dehydrogenase kinase 1 (PDHK1), inhibiting mitochondrial import of pyruvate and facilitating breakdown into lactate. Inhibition of PDHK1 reveals this switch is required acutely for …

Nathan Augustus Cobb: The Father Of Nematology In The United States; And Nathan Cobb's Publications, R. N. Huettel, A. Morgan Golden, Donna Ellington

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Introduction

Nathan Augustus Cobb, referred to as the "Father of Nematology in the United States" (56), was a Renaissance man and a man of humble beginnings. His early life experiences instilled in him the creativity, fortitude, and self reliance that were needed to raise himself alone from age 14, to complete college with little formal pre-college education, receive his Ph.D. in Germany, and go on to found a new discipline of science called "Nematology". His scientific and technical accomplishments were impressive, as indicated by the over 250 first-authored manuscripts he produced during his career. He identified over 1000 species of …

Temperature Drives Epidemics In A Zooplankton-Fungus Disease System: A Trait-Driven Approach Points To Transmission Via Host Foraging, Marta S. Shocket, Alexander T. Strauss, Jessica L. Hite, Maja Šljivar, David J. Civitello, Meghan A. Duffy, Carla E. Cáceres, Spencer R. Hall

School of Biological Sciences: Faculty Publications

Climatic warming will likely have idiosyncratic impacts on infectious diseases, causing some to increase while others decrease or shift geographically. A mechanistic framework could better predict these different temperature-disease outcomes. However, such a framework remains challenging to develop, due to the nonlinear and (sometimes) opposing thermal responses of different host and parasite traits and due to the difficulty of validating model predictions with observations and experiments. We address these challenges in a zooplanktonfungus (Daphnia dentifera–Metschnikowia bicuspidata) system. We test the hypothesis that warmer temperatures promote disease spread and produce larger epidemics. In lakes, epidemics that start earlier and warmer in …

Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, Edward J. Raynor, Larkin Powell, Walter H. Schacht

School of Natural Resources: Faculty Publications

Better understanding animal ecology in terms of thermal habitat use has become a focus of ecological studies, in large part due to the predicted temperature increases associated with global climate change. To further our knowledge on how ground-nesting endotherms respond to thermal landscapes, we examined the thermal ecology of Sharp-tailed Grouse (Tympanuchus phasianellus) during the nesting period. We measured site-specific iButton temperatures (TiB) and vegetation characteristics at nest sites, nearby random sites, and landscape sites to assess thermal patterns at scales relevant to nesting birds. We asked if microhabitat vegetation characteristics at nest sites matched the characteristics that directed macrohabitat …

In Their Own Words: The Significance Of Participant Perceptions In Assessing Entomology Citizen Science Learning Outcomes Using A Mixed Methods Approach, Louise I. Lynch, Jenny Dauer, Wayne A. Babchuk, Tiffany Heng-Moss, Doug Golick

Department of Entomology: Faculty Publications

A mixed methods study was used to transcend the traditional pre-, post-test approach of citizen science evaluative research by integrating adults’ test scores with their perceptions. We assessed how contributory entomology citizen science affects participants’ science self-efficacy, self-efficacy for environmental action, nature relatedness and attitude towards insects. Pre- and post-test score analyses from citizen scientists (n = 28) and a control group (n = 72) were coupled with interviews (n = 11) about science experiences and entomological interactions during participation. Considering quantitative data alone, no statistically significant changes were evident in adults following participation in citizen science when compared to …

Mute Swans, David R. Marks

Wildlife Damage Management Technical Series

Mute swans (Cygnus olor) are an invasive species originally brought to the United States in the late 19th and early 20th centuries for ornamental ponds and lakes, zoos and aviculture collections. Original populations were located in northeastern states along the Hudson Valley but have since expanded to several Midwestern states and portions of the western U.S. and Canada. Mute swan damage includes competing with native waterfowl, destroying native plants, spreading disease, and colliding with aircraft. They are also considered a nuisance in some areas due to their abundant fecal droppings and aggressiveness towards people.

Mute swans can impact …

Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, Eileen Hebets, Melissa Welch-Lazoritz, Pawl Tisdale, Patricia Wonch Hill

Eileen Hebets Publications

Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

Molecular Characterization Of Hard Tick Haemaphysalis Longicornis From China By Sequences Of The Internal Transcribed Spacers Of Ribosomal Dna, Zhong-Bo Li, Guo-Hua Liu, Tian-Yin Cheng

Harold W. Manter Laboratory of Parasitology: Library Materials

In the present study, the entire first and second internal transcribed spacer (ITS-1 and ITS-2) regions of nuclear ribosomal DNA (rDNA) of Haemaphysalis longicornis from China were amplified by polymerase chain reaction. The 45 representative amplicons were sequenced, and sequence variation in the ITS was examined. The ITS sequences of H. longicornis were 3644 bp in size, including the part of 18S rDNA, 28S rDNA sequences and the complete ITS-1, 5.8S rDNA and ITS-2 sequences. Sequence analysis revealed that the ITS-1, 5.8S rDNA and ITS-2 of this hard tick were 1582, 152, and 1610 bp in size, respectively. The intra-specific …

Ureteral Tunnel Length Versus Ureteral Orifice Configuration In The Determination Of Ureterovesical Junction Competence: A Computer Simulation Model, Carlos A. Villanueva, J. Tong, Carl A. Nelson, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

Introduction The long-held belief that a ureteral re-implant tunnel should be five times the diameter of the ureter, as proposed by Paquin in 1959, ignores the effect of the orifice on the occurrence of reflux. In 1969, Lyon proposed that the shape of the ureteral orifice (UO) is more important than the intravesical tunnel. However, both theories missed quantitative evidence from principles of physics. The goal of the current study was to test Lyon’s theory through numerical models (i.e. to quantify the sensitivity of ureterovesical junction (UVJ) competence to intravesical tunnel length and to the UO).

Materials and methods The …
