Human Rights, Environmental Justice, Social Justice, Faith Values And Ethics: Building Stronger Partnerships For The Common Good By Understanding The Differences, Theresa Harris, Leanne M. Jablonski, Sarah Fortner, Malcolm Daniels
Biennial Conference: The Social Practice of Human Rights
Partnerships between human rights practitioners, local communities, scientists, engineers, and health professionals have shown potential to address deeply rooted, systemic human rights concerns. These collaborations are essential for achieving the UN Sustainable Development Goals (SDGs), and for engaging the perspectives and expertise of all constituents. However, even when the individuals in these partnerships or the organizations they represent have common goals, their motivations, analyses, and solutions often come from different perspectives. Members of good will can inadvertently alienate one another when attempting to work together. The fields of human rights, social justice, environmental justice, and ethics have each developed their …

Play Behavior And The Development Of Boldness And Caution In Juvenile Ground Squirrels, Madelene Shehan
Play Behavior And The Development Of Boldness And Caution In Juvenile Ground Squirrels, Madelene Shehan
Creative Activity and Research Day - CARD
We evaluated the relationship between play behavior and the development of boldness in juvenile Belding’s ground squirrels (Urocitellus beldingi). We observed the play behavior of juvenile U. beldingi, and conducted boldness tests at the beginning and toward the end of the developmental period during which play primarily occurs. Behavioral tests consisted of a researcher acting as an intruder, walking toward a juvenile, and noting the distance between the squirrel and intruder at which the juvenile first became aware of the intruder, and the distance at which the squirrel fled. The age of mothers was a significant predictor …

Best Our Husky Compact Reflection for "Seek and Apply Knowledge".
Abstract
The lizardfishes and their allies (Aulopiformes, ~282 species) are investigated from a geometric morphometric approach to study the evolution of body shape changes across habitat transitions in this lineage of fishes. No previous studies have quantitatively examined changes in body shape across lizardfishes and their allies. Over 400 lizardfish specimens were digitized that included representatives from every family of these fishes. We identify that there are distinct patterns of body-shape change across the lizardfish radiation. Body shape trends of cigar-shapes are dominant in inshore and deep-sea benthic …
Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne
Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne
Student Scholar Showcase
Female Dolomedes scriptus, the striped fishing spider, serve as model organisms exhibiting pheromone production as a means of chemical signaling. Previous work has shown that male fishing spiders are responsive to female silk, and preferentially court in the presence of silk from mature virgins. In our research, we hypothesized that mature females produced larger quantities of silk than penultimate females in an attempt to elicit greater male mating response. Female spiders of both age statuses were kept for two days in a gridded tank. Sub-sampling of silk lines that crossed a random portion of the grid produced results signifying …
Co-Occurrence Of Manganese Oxidase Genes Indicates Lateral Transfer Between Classes Of Proteobacteria, Jacob Olichney
Co-Occurrence Of Manganese Oxidase Genes Indicates Lateral Transfer Between Classes Of Proteobacteria, Jacob Olichney
Student Scholar Showcase
Pseudomonas putida GB-1 is a model organism for the study of manganese oxidation in bacteria, however, the frequency of co-localization of multiple known and suspected manganese oxidizing proteins, as well as their occurrence between species, is unknown. Eight different genes isolated from known manganese oxidizing bacteria (MnxG, MopA, McoA, PputGB1_2552, PputGB1_2553, MoxA, MofA, and Bacillus MnxG) were tested individually using BioPython and BLAST (Basic Local Alignment Search Tool) on multiple genomic databases. BLAST searches had an expect value cutoff of 1e-50, limiting gene homologs to those with high sequence similarity. The abundance of homologous genes across classes of proteobacteria point …

DEVELOPMENT OF A MOLECULAR GENETIC METHOD FOR CHARACTERIZING AMPHIBIAN DIETS.Alexander Funk* and Todd W. Pierson, Department of Ecology and Evolutionary Biology, University of Tennessee Knoxville, afunk4@vols.utk.edu
Dietary studies can provide key insights into the ecology and behavior of animals. Methods common in dietary studies of amphibians (e.g., gastric lavage, fecal analysis, dissection) often fail to identify prey beyond the level of Order, are time intensive, and can be biased against soft-bodied prey. Here, we are developing a DNA metabarcoding assay to characterize amphibian diets from non-invasive fecal samples. In DNA metabarcoding, barcoding loci from mixed community samples (e.g., feces) …
Chlorophyll A And Primary Production Dynamics In Kentucky Lake: 2009-2018, Morgan Franklin
Chlorophyll A And Primary Production Dynamics In Kentucky Lake: 2009-2018, Morgan Franklin
Scholars Week
Chlorophyll α (chl α) can be used as a proxy for phytoplankton biomass, while primary productivity (PP), the rate at which carbon is fixed into phytoplankton cells, is an indicator of how quickly carbon is turned over within the phytoplankton community. The purpose of this research was to examine the spatial distribution of chl α seasonally in Kentucky Lake and to examine the relationship between chl α and PP in two embayments of contrasting land use. The two sites analyzed are Ledbetter and Panther embayments. Data analysis showed that the chl α and PP were highly correlated; r=0.45 in Ledbetter …
The Piping Plover Problem: A Review Of Management Issues For A Threatened Shorebird, Andrew Lydeard, Gerry Harris
The Piping Plover Problem: A Review Of Management Issues For A Threatened Shorebird, Andrew Lydeard, Gerry Harris
Scholars Week
Andrew Lydeard and Gerry Harris
The Piping Plover (Charadrius melodus) was federally listed in 1986. Since listing, Piping Plovers have been a focus of conservation and management efforts, particularly on their breeding grounds in the Northern Great Plains, Great Lakes, and northern Atlantic Coast. Despite management efforts that have resulted in range-wide population growth of the Piping Plover, growth in individual populations is often slow and reasons for this are poorly understood. A bias towards understanding drivers of declines on breeding sites compared to wintering and migratory stopover sites may be an underlying cause of this lack of …

Arterial Distribution Of The Human Aorta: An Examination Of The Evolutionary, Developmental, And Physiological Bases Of Asymmetry., Brandon Oddo, Cooker Storm
Seaver College Research And Scholarly Achievement Symposium
The study of anatomy contends that “form follows function”; a disciplinary theme purporting that anatomical structures (i.e., cells, tissues, and organs) have a shape that serves its proper function. With this in mind, it is unclear why human arterial distribution off the aortic arch is asymmetrical, while the corresponding venous anatomy is symmetrical. We investigated the evolutionary, developmental, and physiological bases for the asymmetry of aortic arch branches in humans. First, we investigated the cardiovascular anatomy of ancestral species to determine if, and at what level, anatomical divergence (from aortic symmetry to asymmetry) occurs. Second, we examined the formation of …

Modelling Non-Linear Functional Responses In Competitive Biological Systems., Nickolas Goncharenko
Western Research Forum
One of the most versatile and well understood models in mathematical biology is the Competitive Lotka Volterra (CLV) model, which describes the behaviour of any number of exclusively competitive species (that is each species competes directly with every other species). Despite it's success in describing many phenomenon in biology, chemistry and physics the CLV model cannot describe any non-linear environmental effects (including resource limitation and immune response of a host due to infection). The reason for this is the theory monotone dynamical systems, which was codeveloped with the CLV model, does not apply when this non-linear effect is introduced. For …

Meta-Analysis Of Characteristics In Upper Missouri River Fishes: Prediction Of Invasiveness, Steph Purcell
UNO Student Research and Creative Activity Fair
Invasive species are often considered a global threat due to their association with biodiversity loss and novel diseases. The Missouri-Mississippi River Watershed, including the Missouri River Basin, is particularly vulnerable to invasive species because of low species diversity following historic glaciation events. Management of invasive species is imperative in this watershed but continues to be challenging in that there are over 100 invasive species currently present in this region. The goal of this project is to identify characteristics associated with successful invasions that may assist in developing management strategies to reduce the negative outcomes caused by the establishment of invasive …
Effects Of Rangeland Management On Milkweed Grazing And Monarch Conservation, Brittany Poynor
Effects Of Rangeland Management On Milkweed Grazing And Monarch Conservation, Brittany Poynor
UNO Student Research and Creative Activity Fair
Cattle typically avoid consuming milkweed plants that contain high levels of toxic defense compounds, and therefore many people assume cattle avoid all milkweeds. However, common milkweed (Asclepias syriaca) contains only moderate levels of toxic compounds, and observations suggest that cattle regularly consume common milkweed and may even preferentially graze flowers and leaves of this species. These observations directly relate to efforts to add over one billion stems of milkweed to the central USA for monarch butterfly (Danaus plexippus) conservation. If cattle intentionally consume common milkweed and other milkweed species, and if certain management practices can reduce …
