Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch
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
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- …
Microbiome Assembly And Function In The Solitary Mason Bee, Osmia Lignaria (Megachilidae), Bailey Crowley
Microbiome Assembly And Function In The Solitary Mason Bee, Osmia Lignaria (Megachilidae), Bailey Crowley
All Graduate Theses and Dissertations, Fall 2023 to Present
Animal-microbe interactions can influence host biology, ecology, and evolution. The assembly and function of microbes found within animal hosts oftentimes depends on which species are involved. Advances in sequencing technologies have permitted the exploration of host-microbe interactions in a variety of animals, including bees. Early research aimed at understanding the microbiomes of social bees, such as honey bees and bumble bees, found that microbes prevent the spoilage of stored pollen, breakdown indigestible nutrients into smaller molecules available for uptake by the host, and also protect the host from pathogens. When environmental stressors, such as increased temperatures, disrupt the microbiome, the …

The Interactions Between Drought Tolerant Corn Hybrids And Plant Water-Stress On Weeds And Their Host Capability For Spider Mites, Mercy Adhiambo Odemba
All Graduate Theses and Dissertations, Fall 2023 to Present
With climate change, it is predicted that more frequent high temperatures and drought severity will lead to an increase in damage caused by pests that thrive under these conditions. Spider mite outbreaks, for example, are associated with plant waterstress and there is evidence that some weeds are more resilient and adapted to drought than some crops, leading to major concerns for the management of these two pest types. Weeds directly compete with crops for limited resources, but what is unclear is which weeds harbor spider mites and whether they exacerbate the impact of spider mites on corn crops under water-stressed …

Application Of Criminology In Urban Ecology And Evolution: Routine Activity Theory And Field Equipment Disappearance Dynamics, Ignacy Stadnicki, Michela Corsini, Marta Szulkin
Biology Faculty Publications and Presentations
Research in urban ecology and evolution relies on the use of deployable scientific equipment. If left unattended in the field, scientific equipment may be prone to vandalism and theft, especially in the urban space. Here, we empirically applied a theory derived from the field of criminology, specifically the Routine Activity Theory (RAT) framework, to predict disappearance rates of scientific equipment in an ongoing urban ecology research project. First, we tested a routinely applied method of equipment protection – labelling – and investigated whether equipment disappearance varied with label information content and message tone. Second, we examined whether equipment attributes (price, …

How Will Climate Change-Induced Increases In Wildfire Frequency Affect Soil Microbial Communities?, Bahar Saadaie Jahromi
Waldo Library Student Exhibits
As climate change progresses, wildfires will become more common, increasing their impact on soil microbial ecosystems. This research examines how increased fire frequency affects soil microbial communities and whether effects differ for communities associated with different tree species. Soil samples were collected from under five individuals of four tree species within each of four 1-ha plots that had experienced fire from 24 to 111 years ago. Samples were analyzed for microbial DNA using next generation sequencing techniques in order to explore the influence of fire return interval and tree species on microbial diversity and community structure. Correlations were also examined …
Removal As A Control Method For Trachemys Scripta Elegans And The Response Of Chrysemys Picta Bellii, Jacob Daniel Swanson
Removal As A Control Method For Trachemys Scripta Elegans And The Response Of Chrysemys Picta Bellii, Jacob Daniel Swanson
University Honors Theses
The red-eared slider is considered one of the most ubiquitous freshwater turtles globally. Several key ecological advantages and life history traits of this species jointly impact growth rates and survivorship of native freshwater turtles where sympatry occurs. Evaluation of current management actions for red-eared slider turtles is limited, resulting in a paucity of information to guide management for the species and conservation of declining native freshwater turtles. We used previously collected mark-recapture and removal sampling data from sites with sympatric populations of red-eared slider and western painted turtles. We examined the effects of control (trapping and removal) of red-eared sliders …
Prochlorococcus Death By A Ubiquitous Zooplankton Filter Feeder, Avery E. Harman
Prochlorococcus Death By A Ubiquitous Zooplankton Filter Feeder, Avery E. Harman
University Honors Theses
Prochlorococcus is a globally abundant cyanobacterium that can help reveal the ecology of microorganisms in the ocean. Specifically, mortality by zooplankton such as appendicularians is globally important and Prochlorococcus can help reveal some of the choices made around feeding for this ubiquitous filter feeder. Two ecotypes of Prochlorococcus were introduced to appendicularians to determine if appendicularian feed selectively between these ecotypes. Further, a single ecotype of Prochlorococcus was fed to appendicularians over a variety of life stages to determine if retention rate changed with appendicularian life stage. My results reveal that there is no significant selection between the two Prochlorococcus …

Heterogeneous Resources In Infrastructures Of The Edge Network Paradigm: A Comprehensive Review, Qusay S. Alsaffar, Leila Ben Ayed
Karbala International Journal of Modern Science
The late 1990s saw the rise of the edge computing network paradigm, as well as an increase in the number of IoT de-vices. This concept is viewed as a link between cloud servers and end-devices, bringing processing and storage re-sources closer to clients. As a result of its low latency and high performance, researchers and developers have expressed interest in it. However, this paradigm confronts a number of obstacles and restrictions, including restricted and hetero-geneous resources at network edges. In this paper, we provide a detailed review of heterogeneous resources in edge network infrastructures using a three-dimensional method. These three …

Effects Of Light Intensity And Predator Chemical Cues On Juvenile And Adult Daphnia Magna Diel Vertical Migration, Mira Johnson
Effects Of Light Intensity And Predator Chemical Cues On Juvenile And Adult Daphnia Magna Diel Vertical Migration, Mira Johnson
Lawrence University Honors Projects
Many species of zooplankton exhibit the predator avoidance behavior called diel vertical migration (DVM). During typical DVM, zooplankton ascend to surface waters during the night and descend to deeper water during the day where predation by visual predators is reduced due to lower light levels (Goldman and Horne 1983; Wetzel 1983). DVM is highly variable and the degree to which it is induced can fluctuate based on factors such as zooplankton size, changes in light intensity, and predator chemical cues (Van Gool and Ringelberg 1995, cited in Weber and Noordwijk 2002). Although DVM has been well studied using the genus …

Context Dynamic feedbacks between physical structure and ecological function drive ecosystem productivity, resilience, and biodiversity maintenance. Detailed maps of canopy structure enable comprehensive evaluations of structure–function relationships. However, these relationships are scale-dependent, and identifying relevant spatial scales to link structure to function remains challenging.
Objectives We identified optimal scales to relate structure heterogeneity to ecological resistance, measured as the impacts of wildfire on canopy structure, and ecological resilience, measured as native shrub recruitment. We further investigated whether structural heterogeneity can aid spatial predictions of shrub recruitment.
Methods Using high-resolution imagery from unoccupied aerial systems (UAS), we mapped structural heterogeneity across …

Applications and Applied Mathematics: An International Journal (AAM)
The application of mathematical biology and dynamical systems has proven to be an effective approach for studying viral infection models. To contribute to this research, our paper proposes a new CHIKV model that takes into account an adaptive immune response and distributed time delays, which accurately reflects the time lag between initial viral contacts and the production of new active CHIKV particles. By analyzing the model’s qualitative behavior, we establish a biological threshold number that can predict whether CHIKV will be cleared from or persist in the body. We demonstrate the global stability of both CHIKV-present and CHIKV-free steady states …

Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason
Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason
Master's Theses
The increase in mercury production through anthropogenic activities has led to a global crisis of mercury pollution that poses a significant threat to the health of both humans and wildlife. Aquatic ecosystems are especially at risk due to the creation of methylmercury, a toxic form of mercury, by sulfate-reducing bacteria in anoxic sediments and soils. Methylmercury enters the food chain where it bioaccumulates in individual organisms and then biomagnified with increasing trophic level. Aquatic birds are useful bioindicators of many pollutants, including mercury, due to their abundance and position in the food chain. Previous studies have primarily focused on mercury …

The Stability Of Epigenetic Variants That Can Act As Loci Causing Phenotypic Change, Raul Faburrieta
Biology Theses
Epigenetic variations are a possible source of heritable phenotypic variation. In this study I focus on phenotypic alterations seen in epigenetic Recombinant Inbred Lines (epiRILs) of Arabidopsis thaliana. These epiRILs allow me to study the effects differentially methylated regions (DMRs) have on phenotypic variance. In a study performed in 2014 by Cortijo et al., they found that DMR’s affect flowering time and root length when grown under greenhouse conditions. In this study, I replicated the Cortijo et al. (2014) study, with some changes, to see whether the same significant eQTL regions are found. I found that, some of the eQTLs …

Synthetic Biology Enablement: From Academic Development To Industrial Transformation, Yan Xiong, Xueqing Ma, Daming Chen, Xiao Liu, Guoping Zhao
Bulletin of Chinese Academy of Sciences (Chinese Version)
Synthetic biology revolutionizes the comprehension of life systems from an engineering perspective, employing a “bottomup” approach in life science research. It adopts an iterative research paradigm of “design-build-test-learn” in life science research and creates engineered new life systems grounded in genomics and systems biology. This provides a new pathway of “from creation to understanding” for life sciences, departing from the traditional reductionist research strategy of “study the whole to understand the parts” and opening up a new culture of “building to understand” the essence of life. Additionally, synthetic biology elevates existing biotechnologies previously based on “simulating natural processes” and “genetic …

Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander
Student Theses and Dissertations
Aerobic metabolism is known to generate damaging ROS, particularly hydrogen peroxide. Reactive oxygen species (ROS) are highly reactive molecules containing oxygen that have the potential to cause damage to cells and tissues in the body. ROS are highly reactive atoms or molecules that rapidly interact with other molecules within a cell. Intracellular accumulation can result in oxidative damage, dysfunction, and cell death. Due to the limitations of H2O2 (hydrogen peroxide) detectors, other impacts of ROS exposure may have been missed. HyPer7, a genetically encoded sensor, measures hydrogen peroxide emissions precisely and sensitively, even at sublethal levels, during …

Mitochondrial dysfunction is a common denominator of neurodegenerative diseases, including hereditary and non-hereditary Amyotrophic Lateral Sclerosis (ALS). Ten percent of ALS cases are hereditary while a majority are sporadic, with no known hereditary link. For effective therapeutic approaches to be developed, there is a need for development of a sporadic animal model to better understand disease mechanism. In previous work, our laboratory developed an animal model (known as mitokiller flies) to study sporadic cases of ALS. The work reported in this honors thesis focuses on the use of optogenetics and electrophysiology recording to study the formation of excessive hydrogen peroxide …

The water-lily clade represents the second earliest-diverging branch of angiosperms. Most of its species belong to Nymphaeaceae, of which the “core Nymphaeaceae”—comprising the genera Euryale, Nymphaea and Victoria—is the most diverse clade. Despite previous molecular phylogenetic studies on the core Nymphaeaceae, various aspects of their evolutionary relationships have remained unresolved. The length-variable introns and intergenic spacers are known to contain most of the sequence variability within the water-lily plastomes. Despite the challenges with multiple sequence alignment, any new molecular phylogenetic investigation on the core Nymphaeaceae should focus on these noncoding plastome regions. For example, a new plastid phylogenomic study on …
