Creating Tools To Determine Whether Katanin 60 Affects Female Rejection Of Males In Drosophila, Joshua R. Isaacson
Electronic Thesis and Dissertation Repository
During courtship, it is vital for organisms to recognize conspecifics because of the costs associated with forming interspecies hybrids. Many organisms use species-specific cues to recognize potential mates. These cues are perceived and evaluated via neural pathways. The genetic basis of how species-specific cues are evaluated and processed into receptive or rejection behaviour remains almost entirely unknown. The gene Katanin 60 (Kat60) has previously been identified as contributing to interspecific mate rejection between Drosophila melanogaster and D. simulans. I use the CRISPR/Cas9 system and RNA interference (RNAi) to confirm if Kat60 influences female receptivity between D. melanogaster and D ...

The Transcriptome Of The Bermuda Fireworm Odontosyllis Enopla (Annelida: Syllidae): A Unique Luciferase Gene Family And Putative Epitoky-Related Genes, Mercer R. Brugler, M. Teresa Aguado, Michael Tessler, Mark Siddall
Publications and Research
The Bermuda fireworm Odontosyllis enopla exhibits an extremely tight circalunar circadian behavior that results in an impressive bioluminescent mating swarm, thought to be due to a conventional luciferase-mediated oxidation of a light-emitting luciferin. In addition, the four eyes become hypertrophied and heavily pigmented, and the nephridial system is modified to store and release gametes and associated secretions. In an effort to elucidate transcripts related to bioluminescence, circadian or circalunar periodicity, as well as epitoky-related changes of the eyes and nephridial system, we examined the transcriptomic profile of three female O. enopladuring a bioluminescent swarm in Ferry Reach, Bermuda. Using ...

The two new species differ from H. saulcyi mainly in shape of chela, which is strongly elongated in both new species.
A New Species Of Microtityus From The British Virgin Islands, West Indies, And New Localities For Other Scorpions (Scorpiones: Buthidae, Scorpionidae), Luis F. De Armas
Microtityus (Parvabsonus) eustatia sp. n. is herein described from the British Virgin Islands (West Indies): Eustatia Island (type locality), Virgin Gorda Island, and Camanoe Island, based on seven specimens (three males and four females). The new species closely resembles M. waeringi Francke & Sissom, 1980 from St. John Island and St. Thomas Island, U.S. Virgin Islands, differing mainly by the fixed finger of pedipalp having ten rows of denticles (nine in M. waeringi) and more attenuated metasoma. Also, new localities are recorded for Heteronebo yntemai Francke & Sissom, 1980 (Scorpionidae) and Centruroides griseus (C. L. Koch, 1844) (Buthidae).

Study Of The Visual Adaptation Mechanism In Marine Species With The Change Of Habitation Depth., 2018 Physical-Technical High School
Study Of The Visual Adaptation Mechanism In Marine Species With The Change Of Habitation Depth., Demid Osipov, Daniil Moshnikov
The International Student Science Fair 2018
The goal of our work was to determine the principal mechanisms that provide the difference in visual perception of two marine species that live on different depths: T. Pacificus and O. Vulgaris. In nature, visual perception of species that live deeper is shifted towards the blue region. This is related to the fact that red, orange and yellow light is absorbed more strongly by water than the blue light. On the other hand, the visual perception spectrum of an animal is determined by the absorption spectrum of the "light sensor" located in rods and cones of its eye retina. These ...
Computational Analysis Of Papionini Evolution Using Alu Insertions, 2018 Louisiana State University and Agricultural and Mechanical College
Computational Analysis Of Papionini Evolution Using Alu Insertions, Vallmer Edward Jordan Ii
LSU Doctoral Dissertations
Alu elements are primate specific retrotransposons that have remained active throughout the course of primate evolution. As a result of this sustained mobilization. Alu elements are present in greater copy number in primate genomes than any other transposable element. An average of over one million Alu elements has been identified in every sequenced haplorrhine genome to date. These characteristics qualify Alu elements as ideal characters for studying evolutionary relationship among primates.
The increasing availability of whole genome sequencing data presents novel challenges and opportunities for comparative genomic analyses. Genomic data is now publicly available for most primate species. Such an ...

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Student Theses 2015-Present
This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...
Understanding Patterns Of Diversity And Evolution In Mainland Anolis Lizards, 2018 University of New Mexico
Understanding Patterns Of Diversity And Evolution In Mainland Anolis Lizards, Levi Gray
Patterns of organismal diversity and evolution are often difficult to interpret with a high level of confidence. The number of mechanisms and processes that contribute to shaping patterns of diversity is extensive and is reflected in the many methods researchers have used to infer causation. Taxonomic groups that are well-studied can offer more precise interpretation of pattern and process due to the considerable amount of research addressing ecology, natural history, and behavior of the organisms.
In this dissertation, I explore patterns of phylogenetic and phenotypic variation in Anolis lizards (anoles) by testing hypotheses that could have led to the observed ...

Meiothermus ruber Genome Analysis Project
This project is part of the Meiothermus ruber genome analysis project, which uses the bioinformatics tools associated with the Guiding Education through Novel Investigation –Annotation Collaboration Toolkit (GENI-ACT) to predict gene function. We investigated the biological function of Escherichia coli and Meiothermus ruber proC genes using the complementation assay. In this research project, mutants of varying severity to the functional state of the protein were developed. The results showed that two or more amino acid deletions reduced or eliminated ProC function. Amino acid substitutions, on the other hand, were not severe enough to impact ProC function. Double and triple mutants ...
Diel Rhythmicity Found In Behavior But Not Biogenic Amine Levels In The Funnel-Web Spider Agelenopsis Pennsylvanica (Araneae, Agelenidae), 2018 East Tennessee State University
Diel Rhythmicity Found In Behavior But Not Biogenic Amine Levels In The Funnel-Web Spider Agelenopsis Pennsylvanica (Araneae, Agelenidae), Alexander E. Demarco
Electronic Theses and Dissertations
Quantifying individual differences in behavior and the extent that behavior is influenced by circadian control is of paramount importance in behavioral ecology. In addition, the proximate mechanisms underlying behavior are also critical in order to obtain a more complete picture of how behavior evolves. Biogenic amines (BAs) are simple nitrogenous compounds derived from amino acids and have been consistently and extensively linked to behavior. For this study, we analyzed temporal patterns of BAs in relation to the antipredator (boldness) and aggressive behavior in female Agelenopsis pennsylvanica, a funnel-web spider. Using HPLC-ED, we compared behavioral responses to temporal patterns of octopamine ...
Reproductive Effort And Lipid Dynamics Of The Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York, 2018 State University of New York College at Buffalo - Buffalo State College
Reproductive Effort And Lipid Dynamics Of The Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York, Christopher A. Osborne
Life history theory predicts that reproductive characteristics of organisms will be shaped by biotic and abiotic factors to maximize their overall fitness. In this study, I investigated how growth, reproductive effort, and lipid dynamics vary ontogenetically and seasonally for emerald shiners (Notropis atherinoides) in the upper Niagara River. Growth rates were highest in age 2 shiners and lower in age 1 and age 3 individuals. Evidence of reproduction was found beginning at age 1, and reproductive investment as measured by ovarian lipid content was lowest in age 1 and age 2 individuals and greatest in age 3 fish. All age ...
Evolutionary Conservation Of Midline Repulsion By Robo Family Receptors In Flies And Mice, 2018 University of Arkansas, Fayetteville
Evolutionary Conservation Of Midline Repulsion By Robo Family Receptors In Flies And Mice, Allison Loy
Biological Sciences Undergraduate Honors Theses
As the nervous system develops in animal embryos, neuronal axons are guided to their synaptic targets by extra cellular cues that signal through axon guidance receptors expressed on the surface of the axon. In animals with bilateral symmetry, one of the important decisions made by nearly every axon in the embryonic nervous system is whether to stay on its own side of the body, or to cross the midline and connect to cells on the opposite side. The Roundabout (Robo) family is an evolutionarily conserved group of axon guidance receptors that regulate midline crossing in a wide range of animal ...
Evolutionary Competition As Religion: A Religio-Biological Model Of The Maori And Vaisnava Sahajiya Traditions, 2018 College of William and Mary
Evolutionary Competition As Religion: A Religio-Biological Model Of The Maori And Vaisnava Sahajiya Traditions, Benjamin Highland
Undergraduate Honors Theses
Within the modern field of Religious Studies, there exists an epistemological divide between structuralist and post-structuralist thought. Structuralists seek to find underlying and universally applicable knowledge about religion, while post-structuralists argue that traditions must be studied within their own specific geographic, temporal, and cultural contexts. In an aim to reconcile these two disparate paradigms, I introduce the Religio-Biological Model and apply it to two distinct religious traditions: the Maori and the Vaisnava Sahajiya. Drawing from both religious and biological theory (specifically multilevel selection theory), this thesis seeks to create an interdisciplinary framework for the future study of religion that cohesively ...
