Zero Textbook Cost Syllabus For Env 3009/4900 (Conservation Biology And Sustainable Development), Stephen Gosnell
Open Educational Resources
Conservation biology is an interdisciplinary topic that explores how we can protect and maintain natural areas. Due to the resources we take and impacts we have on natural environments, this field is directly related to restoration ecology (restoring natural areas) and sustainable development/natural resource management. We will explore the basis for these related fields from an ecological, social, legal, and cultural perspective, as all conservation and management projects take place in the larger human landscape. We will consider how we measure biodiversity, why it matters, why is it is threatened, and how we can manage (protect, restore, maintain, use) it …

Chronic inflammation has been recognized as a risk factor for the development and maintenance of malignant disease. Cytokines such as interleukin-6 (IL-6), oncostatin M (OSM), and interleukin-1 beta (IL-1β) promote the development of both acute and chronic inflammation while promoting in vitro metrics of breast cancer metastasis. However, anti-IL-6 and anti-IL-1β therapeutics have not yielded significant results against solid tumors in clinical trials. Here we show that these three cytokines are interrelated in expression. Using the Curtis TCGA™ dataset, we have determined that there is a correlation between expression levels of OSM, IL-6, and IL-1β and reduced breast cancer patient …

H/L Ratio As A Measurement Of Immune Function In Terrapene Ornata Species, Vesa Govori
Honors Theses
White blood cells are a key part of the immune system, and changes in white cell count can reveal the overall state of health and the immune systems functional ability of a species. White blood such as heterophils and lymphocytes are essential for being able to fight off infections. Analyzing different cell ratios has been commonly done before as a way to observe immune function in bird species as well as other species. Understanding that there are different functions between the different white blood cells provides an extra interesting perspective to what could be happening in the immune system function …

Using Motion-Activated Trail Cameras To Study Diet And Productivity Of Cliff-Nesting Golden Eagles, Jordan T. Harrison, Michael N. Kochert, Benjamin P. Pauli, Julie A. Heath
Raptor Research Center Publications and Presentations
Studies of cliff-nesting raptors can be challenging because direct observations of nest contents are difficult. Our goals were to develop a protocol for installing motion-activated trail cameras at Golden Eagle (Aquila chrysaetos) nests to record diet information and productivity, and to estimate prey detection probability using different diet study methods. In 2014 and 2015, we installed cameras at 12 Golden Eagle nests with 18–42-d-old nestlings. Following installation, we monitored adult behavior using direct observation and post-installation image review. At two nests, adult eagles did not return to nests or exhibited behaviors suggesting avoidance of the cameras, but returned …
Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch
Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch
Honors Theses
With perceived student resistance to active learning in the classroom, instructors are hesitant to implement such methods into their classroom structure despite how effective they may be. This research seeks to understand student perceptions related to the transition to higher prevalence of active learning techniques. We aimed to find answers to how students perceive the ideal classroom to be structured, what reasons they perceive for lecture and active learning components, and possible explanations to concerns of groupwork during class time. We analyzed 64 interviews with undergraduate biology students at the University of Nebraska- Lincoln, developed coding rubrics from commonly found …
Investigating The Role Of Free Radicals In Huntington's Disease Using Drosophila Melanogaster, Jennifer Libov
Investigating The Role Of Free Radicals In Huntington's Disease Using Drosophila Melanogaster, Jennifer Libov
Honors Theses
During normal cell metabolism, reactive oxygen species (ROS) are produced as a byproduct of oxidative phosphorylation. ROS are utilized in the cell as a signaling molecule and can be maintained at healthy levels by cellular antioxidants. However, when the cell experiences oxidative stress due to environmental or genetic conditions, levels of ROS can exceed healthy levels and inhibit necessary life functions by damaging biomolecules and cellular structures. This loss of function can lead to physiological decline and neurodegeneration, such as in diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and, potentially, Huntington’s disease. The following experiments use the model genetic organism …

Mitochondria are essential organelles in most eukaryotic cells because of their role in metabolism and the production of ATP by the oxidative phosphorylation (OXPHOS) pathway, as well as other key cellular processes. Metal cofactors, such as copper (Cu) and iron (Fe), are incorporated into OXPHOS protein complexes of yeast located within the inner membrane of the mitochondria. Misincorporation or modulation of these available metals in mitochondrial enzymes leads to the production of reactive oxygen species (ROS). ROS are reactive molecules containing oxygen such as peroxides, superoxide, and hydroxyl radicals. Yeast are a good model for studying aging and the effect …

Betting & Hierarchy In Paleontology, Leonard Finkelman
Betting & Hierarchy In Paleontology, Leonard Finkelman
Faculty Publications
In his Rock, Bone, and Ruin: An Optimist’s Guide to the Historical Sciences, Adrian Currie argues that historical scientists should be optimistic about success in reconstructing the past on the basis of future research. This optimism follows in part from examples of success in paleontology. I argue that paleontologists’ success in these cases is underwritten by the hierarchical nature of biological information: extinct organisms have extant analogues at various levels of taxonomic, ecological, and physiological hierarchies, and paleontologists are adept at exploiting analogies within one informational hierarchy to infer information in another. On this account, fossils serve the role …

The evolution of multicellular metazoan organisms was marked by the inclusion of an extracellular matrix (ECM), a multicomponent, proteinaceous network between cells that contributes to the spatial arrangement of cells and the resulting tissue organization. The development of an ECM that provides support in larger organisms may have represented an advantage in the face of selection pressure for the evolution of the ECM.

Many fields and sectors are using mobile applications to facilitate their services. Education is an important field that can utilize the various features of mobile applications to assist students and educators. Students are learning several subjects and concepts in schools, including biology. With traditional teaching methods, students may face difficulties in grasping knowledge about human anatomy. This can affect the teaching effectiveness, students' learning process, their engagement in class, and their academic performance. …

Bacterial symbionts are integral to the health and homeostasis of invertebrate hosts. Notably, members of the Rickettsiales genus Wolbachia influence several aspects of the fitness and evolution of their terrestrial hosts, but few analogous partnerships have been found in marine systems. We report here the genome, phylogenetics, and biogeography of a ubiquitous and novel Rickettsiales species that primarily associates with marine organisms. We previously showed that this bacterium was found in scleractinian corals, responds to nutrient exposure, and is associated with reduced host growth and increased mortality. This bacterium, like other Rickettsiales, has a reduced genome indicative of a parasitic …

A unique aspect of electrostimulation (ES) with nanosecond electric pulses (nsEP) is the inhibition of effects when the polarity is reversed. This bipolar cancellation feature makes bipolar nsEP less efficient at biostimulation than unipolar nsEP. We propose to minimize stimulation near pulse-delivering electrodes by applying bipolar nsEP, whereas the superposition of two phase-shifted bipolar nsEP from two independent sources yields a biologically-effective unipolar pulse remotely. This is accomplished by electrical compensation of all nsEP phases except the first one, resulting in the restoration of stimulation efficiency due to cancellation of bipolar cancellation (CANCAN-ES). We experimentally proved the CANCAN-ES paradigm by …
