Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch 2024 Clark University

Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch

Biology

Background: Transcription factor (TF) proteins are a key component of the gene regulatory networks that control cellular fates and function. TFs bind DNA regulatory elements in a sequence-specific manner and modulate target gene expression through combinatorial interactions with each other, cofactors, and chromatin-modifying proteins. Large-scale studies over the last two decades have helped shed light on the complex network of TFs that regulate development in Drosophila melanogaster. Results: Here, we present a detailed characterization of expression of all known and predicted Drosophila TFs in two well-established embryonic cell lines, Kc167 and S2 cells. Using deep coverage RNA sequencing approaches we …


Effects Of Roadways On Seasonal Movement Strategies And Mate Location Success In An Imperiled Pit Viper (Crotalus Horridus), Elizabeth J. Noble 2024 Georgia College and State University, Milledgeville, GA 31061

Effects Of Roadways On Seasonal Movement Strategies And Mate Location Success In An Imperiled Pit Viper (Crotalus Horridus), Elizabeth J. Noble

Graduate Research Showcase

A detailed understanding of animal movement behavior is fundamental to effective conservation and management. Within populations, a diversity of movement strategies can be displayed in search of critical resources, and these strategies are influenced by multiple interacting factors related to individuals and the environment. Mating partners are one critical resource that often serves as a prominent selective force shaping movement during mating seasons. For many large-bodied snakes, such as pit vipers (Viperidae: Crotalinae), male mate- searching movements are the primary determinant of mate location success. During this time, males incur significant risks associated with elevated movement. In an increasingly human- …

Spatial Ecology Of Mule Deer Migrations From Grand Teton National Park And The Teton Range, Justin K. Schwabedissen 2024 Utah State University

Spatial Ecology Of Mule Deer Migrations From Grand Teton National Park And The Teton Range, Justin K. Schwabedissen

All Graduate Theses and Dissertations, Fall 2023 to Present

The Greater Yellowstone Ecosystem hosts several of the longest, fully intact ungulate migrations remaining in the continental United States. However, expanding development and an increasing human footprint continue to truncate migratory routes. While the endpoints are often a seasonal range on protected lands, these migration corridors frequently cross other jurisdictional boundaries, including large tracts of private or multiple-use lands, with varying levels of protection. Thus, it is critical resource managers understand the dynamics of migratory movements to define population-level corridors and prioritize appropriate conservation strategies. Mule deer in Wyoming have been documented traveling long distances between summer and winter ranges; …


Mate Guarding Against Strong Men Displaying Affiliative And Aggressive Humor, Jacob Pauley 2024 University of Arkansas, Fayetteville

Mate Guarding Against Strong Men Displaying Affiliative And Aggressive Humor, Jacob Pauley

Biological Sciences Undergraduate Honors Theses

Mate retention behaviors serve to discourage partner defection from a current pairbond. Such behaviors are oftentimes more prevalent toward intrasexual rivals exhibiting physical and behavioral cues implicating that rival as an optimal mate. Among these features in men are their upper body strength, a feature diagnostic of heritable fitness, and men's ability to produce humor, a cue to their social competence. This study considered the intersection of these desirable features in shaping men's mate retention behavior toward an intrasexual rival. After learning of a hypothetical interloper exhibiting high or low upper body strength while similarly using humor in an affiliative …

Towards Understanding The Function Of An Ets-Like Gene In Nematostella Vectensis: Generation Of A Knockout Mutant Line And A Transgenic Reporter Line, Emily Bullock

Biological Sciences Undergraduate Honors Theses

Due to their unique phylogenic position as sister to Bilateria, Cnidaria are often credited with the utility of allowing for reconstruction of ancestral biology based on characteristics shared with bilaterians and other animals. This factor makes investigation into the nervous systems of cnidarians critical in understanding early neural evolution. Wamides, a class of neuropeptides, have been shown to play a regulatory role in life cycle transitions across many different species. The cnidarian specific Wamide neuropeptide, GLWamide, has previously been identified to play an accelerator role in the metamorphic timing of a specific species of sea anemone, Nematostella vectensis. However, …

The XRD pattern verifies that the ZnO was successfully synthesized and immobilized onto the PPAC in a one pot synthesis system. The surface areas of ZnOPPAC and PPAC adsorbents were 13.62 m2/g and 961.96 m2/g, respectively. The FTIR evaluation of the ZnO-PPAC adsorbent revealed several …


Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener 2024 Bowling Green State University

Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener

Honors Projects

There are three different types of eyes, the simple eye, the compound eye, and the camera eye (Cambridge Dictionary) (Myer-Rochow, 2014) (UCL, 2020). The retina of the eye has evolved and adapted to fit the lifestyles of the respective organisms. Because of this part of the eye, organisms are able to see different colors and use light to define the world using photoreceptors. Photoreceptors are rod cells, which are light sensitive and process light, and cone cells, which perceive the different color wavelengths, that pass visual information to the brain (Kazilek, 2010). About 5% of the photoreceptors in the retinas …

Carbon Sequestration And Its Role In Mitigating Climate Change, Mallory Woodward 2024 Arkansas Tech University

Carbon Sequestration And Its Role In Mitigating Climate Change, Mallory Woodward

ATU Research Symposium

Carbon sequestration is when carbon dioxide is stored in ecosystems like grasslands forests, soils and oceans. Wetlands are one of the many important ecosystems that sequester carbon and act as a carbon sink. The U.S. Energy Information Administration estimates that in 2019 33,621.5 million metric tons of carbon were released into the atmosphere globally, due to human emissions. Anthropogenic carbon emissions have rapidly increased over the past 150 years. Since 1982, The global rate of warming is more than three times as fast, currently rising 0.36 degrees Fahrenheit each decade, and the rate will continue to increase. How do wetlands …
