A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko
A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko
Senior Honors Projects
Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a …
C-Myc’S Role On Methylation Of The Gata-2 Gene In Non-Small Cell Lung Carcinoma, Jonathan D. Hajduk
C-Myc’S Role On Methylation Of The Gata-2 Gene In Non-Small Cell Lung Carcinoma, Jonathan D. Hajduk
Student Scholar Showcase
Lung cancer accounts for more deaths per year than any other form of cancer, resulting in a total of 158,000 deaths per year in the U.S. Non-small cell lung cancer (NSCLC) is diagnosed in greater than 224,000 Americans every year. Methylation and subsequent downregulation of certain genes has been directly linked to the uncontrolled growth of NSCLC cells. Natural killer (NK) cells are key innate immune cells responsible for apoptosis of cells with incorrect genetic code. It is believed that one component of uncontrolled NSCLC growth is due to the NK cells’ inability to detect errors within NSCLC cells. Perhaps …

Genetic Effect Of Drought On The California Newt, Taricha Torosa, Madeleine M. Perrault, Samantha Fiallo, Alero Arueyingho, Cindy Kim, Laiken Ritchie
Seaver College Research And Scholarly Achievement Symposium
Droughts are now a common occurrence in Southern California and are known to cause population declines in many species, and such bottlenecks can cause a loss of genetic variation. Genetic variation was examined in a population of the California newt located in Arroyo Sequit Creek in the Santa Monica Mountains. Genetic data from animals examined prior to the current drought were compared to similar data collected from the population after it experienced several years of severe drought. We hypothesized that the drought impacted population should show less genetic variation in comparison to the pre-drought population. Nevertheless, there were no genetic …
Taxonomic Placement Of The Nidulariaceae Of Nebraska And Iowa Based On Molecular And Morphological Data, Goodmond H. Danielsen Iv
Taxonomic Placement Of The Nidulariaceae Of Nebraska And Iowa Based On Molecular And Morphological Data, Goodmond H. Danielsen Iv
UNO Student Research and Creative Activity Fair
Proper taxonomic and molecular study is necessary to better organize closely related species that may not only be used for human needs, but also in the quest for knowledge of how the world around us works. Though important, the taxonomic placement of Nebraskan and Iowan bird’s nest fungi (Nidulariaceae) is not well documented. Here, phylogenetic analysis is used to place the Nidulariaceae of Nebraska and Iowa in the tree of life using molecular and morphological techniques. Based on these results and results of further work done on these specimens, it will be possible to better place the Nidulariaceae of Nebraska …
