Landscape Of Stress: Does Drought Prevail Over Anthropogenic Activity In Influencing Cortisol Levels And Fitness In The Pacific Fisher?, Jennifer R. Kordosky
All Graduate Theses and Dissertations
Fishers (Pekania pennanti) are a species of concern in the Sierra Nevada Mountains of California. Cortisol is a glucocorticoid hormone released to mobilize energy in response to stress and has been used as an indication of an individual’s physiological response to its environment. By collecting samples of fisher hair and measuring an individual’s cortisol, we examined the physiological stress response of the animals to human disturbances (housing density, road density, habitat type, and silvicultural treatements) and drought (tree mortality) in their home ranges. Using AICc model selection, we found that levels of tree mortality within a fisher’s ...
Reduced-Impact Logging For Climate Change Mitigation (Ril-C) Can Halve Selective Logging Emissions From Tropical Forests, Anand Roopsind
Biology Faculty Publications and Presentations
Selective logging causes at least half of the emissions from tropical forest degradation. Reduced-impact logging for climate (RIL-C) is proposed as a way to maintain timber production while minimizing forest damage. Here we synthesize data from 61 coordinated field-based surveys of logging impacts in seven countries across the tropics. We estimate that tropical selective logging emitted 834 Tg CO2 in 2015, 6% of total tropical greenhouse gas emissions. Felling, hauling, and skidding caused 59%, 31%, and 10% of these emissions, respectively. We suggest that RIL-C incentive programs consider a feasible target carbon impact factor of 2.3 Mg emitted ...
Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, 2019 University of Southern Maine
Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, Aaron Svedlow
Climate change and weather affect the phenology of bird migration; however, specific climatological factors associated with these observed effects have only recently been described. The relationship between local, regional, and global climate patterns and avian migration are increasingly important to understand due to the widespread, and potentially negative, implications (such as reduced fecundity) of rapid human induced climate change on bird populations. Migratory birds are under selective pressure to arrive at breeding areas at the optimal time to set up nesting territories and exploit seasonally abundant food resources, and because climate change has the potential to occur more rapidly than ...

Characterization Of Psychromonas Aquimarina, A New Model Organism For Climate Change, 2019 Harrisburg University of Science and Technology
Characterization Of Psychromonas Aquimarina, A New Model Organism For Climate Change, Carrie Carpenter
Experiential Learning Projects
The current increase of average global temperature puts 25 to 35 percent of plant and animal species at an increased risk of extinction (Climate Change, 2018). Changing any environmental factor, such as increasing growth temperature, can significantly impact any organisms’ ability to survive. Because of the diversity of organisms on the planet, it is not feasible to study how each individually might adapt, but rather it is more efficient to study select organisms. This research focuses on a psychrophilic bacterium, Psychromonas aquimarina, which can survive in colder regions where most bacteria would not. This bacterium was chosen because climate change ...
Refernment: An R Package For Annotating Rna Editing In Plastid Genomes, 2019 Utah State University
Refernment: An R Package For Annotating Rna Editing In Plastid Genomes, Tanner A. Robison, Paul G. Wolf
Paul G. Wolf
PREMISE OF THE STUDY: In the absence of cDNA, the annotation of RNA editing in plastomes must be done manually, representing a significant time cost to those studying the organellar genomes of ferns and hornworts.
METHODS AND RESULTS: We developed an R package to automatically annotate apparent nonsense mutations in plastid genomes. The software successfully annotates such sites and results in no false positives for data with no sequencing or assembly errors.
CONCLUSIONS: Compared to manual annotation, ReFernment offers greater speed and accuracy for annotating RNA editing sites. This software should be especially useful for researchers generating large numbers of ...

A Stimulatory Role For Cytokinin In The Arbuscular Mycorrhizal Symbiosis Of Pea, 2019 Wilfrid Laurier University
A Stimulatory Role For Cytokinin In The Arbuscular Mycorrhizal Symbiosis Of Pea, Dane M. Goh, Marco Cosme, Anna B. Kislala, Samantha Mulholland, Zakaria M.F. Said, Lukáš Spíchal, R.J. Neil Emery, Stéphane Declerck, Frédérique C. Guinel
Biology Faculty Publications
The arbuscular mycorrhizal (AM) symbiosis between terrestrial plants and AM fungi is regulated by plant hormones. For most of these, a role has been clearly assigned in this mutualistic interaction; however, there are still contradictory reports for cytokinin (CK). Here, pea plants, the wild type (WT) cv. Sparkle and its mutant E151 (Pssym15), were inoculated with the AM fungus Rhizophagus irregularis. E151 has previously been characterized as possessing high CK levels in non-mycorrhizal (myc-) roots and exhibiting high number of fungal structures in mycorrhizal (myc+) roots. Myc- and myc+ plants were treated 7, 9, and 11 days after inoculation (DAI ...
Optogenetic Stimulation Of Drosophila Heart Rate At Different Temperatures And Ca2+ Concentrations, 2019 University of Kentucky
Optogenetic Stimulation Of Drosophila Heart Rate At Different Temperatures And Ca2+ Concentrations, Yuechen Zhu, Henry Uradu, Zana R. Majeed, Robin L. Cooper
Robin L. Cooper
Optogenetics is a revolutionary technique that enables noninvasive activation of electrically excitable cells. In mammals, heart rate has traditionally been modulated with pharmacological agents or direct stimulation of cardiac tissue with electrodes. However, implanted wires have been known to cause physical damage and damage from electrical currents. Here, we describe a proof of concept to optically drive cardiac function in a model organism, Drosophila melanogaster. We expressed the light sensitive channelrhodopsin protein ChR2.XXL in larval Drosophila hearts and examined light‐induced activation of cardiac tissue. After demonstrating optical stimulation of larval heart rate, the approach was tested at low ...

Serotonin modulates various physiological processes and behaviors. This study investigates the role of 5-HT in locomotion and feeding behaviors as well as in modulation of sensory-motor circuits. The 5-HT biosynthesis was dysregulated by feeding Drosophila larvae 5-HT, a 5-HT precursor, or an inhibitor of tryptophan hydroxylase during early stages of development. The effects of feeding fluoxetine, a selective serotonin reuptake inhibitor, during early second instars were also examined. 5-HT receptor subtypes were manipulated using RNA interference mediated knockdown and 5-HT receptor insertional mutations. Moreover, synaptic transmission at 5-HT neurons was blocked or enhanced in both larvae and adult flies. The ...
The Cytoplasmic Tail Domain Of The Vacuolar Protein Sorting Receptor Vps10p And A Subset Of Vps Gene Products Regulate Receptor Stability, Function, And Localization, 2019 University of California, San Diego
The Cytoplasmic Tail Domain Of The Vacuolar Protein Sorting Receptor Vps10p And A Subset Of Vps Gene Products Regulate Receptor Stability, Function, And Localization, Joan Lin-Cereghino, Eric G. Marcusson, Scott D. Emr
VPS10 of Saccharomyces cerevisiae encodes a type I transmembrane receptor protein required for the sorting of the soluble vacuolar hydrolase carboxypeptidase Y (CPY). To characterize the essential structural features and intercompartmental transport itinerary of the CPY receptor, we have constructed mutant forms of Vps10p that alter the carboxyterminal cytoplasmic tail of the protein. In addition, we have analyzed the effect these mutations as well as mutations in several VPS genes have on the function, stability, and localization of Vps10p. Although wild-type Vps10p is very stable over a 3-h chase period, overproduction of Vps10p results in PEP4-dependent degradation of the receptor ...
Assessment Of Dietary Patterns Represents A Potential, Yet Variable, Measure Of Inflammatory Status: A Review And Update, Mariana C. Calle, Catherine J. Andersen
Chronic low-grade, systemic inflammation is a well-characterized risk factor in the development of chronic metabolic diseases, such as cardiovascular disease, type 2 diabetes, and metabolic syndrome. Diet could be an effective strategy for reducing inflammation associated with chronic disease. While anti-inflammatory properties of isolated dietary bioactive and functional foods have been routinely studied, the evaluation of dietary patterns on inflammation warrants further review—especially given the recent inclusion of dietary pattern recommendations into dietary guidelines and policies. Therefore, the objective of this narrative review is to examine current evidence linking diet to low-grade, systemic inflammation within the context of chronic ...
Pvsripo Effect On Cancer, 2019 Nova Southeastern University
Pvsripo Effect On Cancer, Vishal Jindal, Matthew Lee, Darshan Rola, Mir Saleem
PVSRIPO, a variant of the poliovirus, is a revolutionary virus that demonstrates key characteristics for oncolytic virotherapy due to its ability to attack glioblastomas. The first criteria that PVSRIPO demonstrates is tumor-targeting tropism. PVSRIPO binds to nectin-like molecule 5 (Necl-5), a poliovirus receptor (PVR), found on different types of cancers such as lung cancer, colorectal cancer, and glioblastomas. This allows the virus to have a high binding affinity to tumor cells. Secondly, after modifying the poliovirus by substituting its internal ribosome entry site (IRES) with the Human Rhinovirus 2's (HRV2) IRES, the poliovirus becomes PVSRIPO, an attenuated version of ...

Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari
Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as ...

Chemical Alternatives For Managing Key Stored Product Insects, 2019 South Carolina State University, Orangeburg, SC
Chemical Alternatives For Managing Key Stored Product Insects, Rizana M. Mahroof
Journal of the South Carolina Academy of Science
In this short review paper, possible alternatives to manage some key stored product insects pests are discussed. With the phase out of methyl bromide and insects developing resistance to phosphine, fumigants available to manage stored product insects are becoming limited. Potential non-chemical alternatives, those are environmentally benign and do not leave harmful residues on treated products are most favoured. Two techniques; sex pheromone based mating disruption and ozone gas, are explored as safer insect management tools in this paper.
Evaluation Of The Efficacy Of A Novel Dna Vaccine Against Toxoplasma Gondii, 2019 University of Nebraska at Omaha
Evaluation Of The Efficacy Of A Novel Dna Vaccine Against Toxoplasma Gondii, Rosalie Warner
Student Research and Creative Activity Fair
Toxoplasma gondii is an obligate intracellular parasite that has the ability to infect all nucleated mammalian cells and is found worldwide. This protozoan parasite can cause severe ocular and neurological disease in immunocompromised persons and fetuses. While there are treatments available for individuals infected with the tachyzoite stage of the parasite, which defines the acute infection, there is no effective way to treat for the latent cyst forming stage which is associated with behavioral changes. Thus, there is a need for an effective protective vaccine. This work highlights the design of a versatile DNA sequence that will function in conjunction ...
Isolating And Characterizing Novel Bacteriophages From Freshwater Samples, 2019 University of Nebraska at Omaha
Isolating And Characterizing Novel Bacteriophages From Freshwater Samples, Mackenzie Conrin, Avery Misfeldt
Student Research and Creative Activity Fair
Bacteria are responsible for many Healthcare-Associated infections each year and are evolving to become multidrug resistant (MDR). Bacteriophages, also called phages, are naturally occurring bacterial viruses. These phages infect and kill their bacterial hosts. It is estimated that there are 10 different phages, per bacterium. This makes phages the most abundant entity in the biosphere. Isolating and characterizing these naturally occurring bacterial killers offers the potential for strain specific treatment of MDR infections. Such treatments, coined Phage Therapy, can be used in the fight against evolving bacterial infections. Pseudomonads are a classification of bacteria that infect a variety of plants ...
