Feasibility For Utilization Of A Freshwater Pulmonate Snail, Physa acuta, As A Model Organism For Environmental Toxicity Testing, With Special Reference To Cadmium Ion Toxicity
(Biology, 2007-08-23)The benefits of developing the pond snail, Physa acuta, as a model species for testing acute and chronic toxicity of aquatic pollutants include its wide North American distribution, ease of field collection and laboratory ... -
The Food Habits and Feeding Behavior of New World Coral Snakes
(University of Texas at Arlington Libraries, 1973-05-01)This thesis considers the food habits and feeding behavior of New World venomous coral snakes, with emphasis on Micrurus fulvius a species that is found in the southeastern United States and northern Mexico. Literature records ... -
Functional Analysis of Nuclear-Encoded Mitochondrial Gene Duplicates with Testis-Biased Expression in Drosophila melanogaster
(2019-08-12)Most of the genes encoding proteins that function in the mitochondria are located in the nucleus and are called nuclear-encoded mitochondrial genes (N-mt genes). In Drosophila melanogaster, most of the tissue-specific ... -
FUNCTIONAL GENOMICS REVEALS THE MECHANISMS AND EVOLUTION OF EXTREME PHYSIOLOGICAL ADAPTATIONS IN SNAKES
(2021-04-28)Previous studies examining post-feeding organ regeneration in the Burmese python (Python molurusbivittatus) have identified thousands of genes that are significantly differentially regulated during this process. However, ... -
Gene Expression Differences in Hybrids at Beginning of Speciation Continuum
(2016-09-16)The formation of new species results from reproductive isolation, or the barrier to successful mating between organisms of divergent populations. The degree of reproductive isolation can be measured by the reduction in ... -
GENETIC BASIS OF MELANIN PIGMENTATION AND SEXUAL DICHROMATISM IN DOMESTIC PIGEONS
(2016-12-09)Deciphering the genetic basis of pigmentation in domestic pigeons (Columba livia) affords a unique opportunity to connect microevolution to macroevolution. Domestic pigeons have far greater phenotypic diversity than other ... -
Genetic Determinants Of Reproductive Isolation In Xenopus
(Biology, 2007-09-17)Haldane's rule states that in F1 interspecific hybrids the heterogametic sex (XY or ZW) suffers the most dysfunctional effects of hybridization. Frogs of the genus Xenopus have ZW sex determination yet hybrid males are ... -
GENETIC INNOVATION THROUGH GENE DUPLICATION IN DROSOPHILA
(2021-08-13)Among several mechanisms, whole gene duplication is one of the major sources for the generation of new genes. A large portion of young genes that emerged through whole gene duplication in Drosophila are specifically expressed ... -
GENOMIC STRUCTURE AND DIVERSITY IN NEOTROPICAL HERPETOFAUNA: THE ROLE OF DEMOGRAPHIC HISTORY AND GENE FLOW
(2021-08-03)The effects of genetic introgression on species boundaries and how they affect species’ integrity and persistence over evolutionary time have received increased attention. The increasing availability of genomic data has ... -
Geographic Variation In The Morphometrics Of Emydoide blandingii
(Biology, 2007-08-23)Morphometric measurements were taken from museum specimens Emydoidea blandingii. Samples were taken from Michigan, Wisconsin, Illinois, Iowa, Nebraska, New York and Minnesota as well as from Ontario, Canada. Populations ... -
GLOBAL MAPPING OF PROTEIN-NUCLEIC ACID INTERACTION OF THE RLE LINE R2Bm
(2022-05-17)The R2 Long Interspersed Nucleotide Elements (LINEs) is a widely distributed site specific non-LTR retrotransposons that integrates exclusively into host genome’s 28s rRNA genes and replicate by a process called Target ... -
GLOBULAR DOMAIN STRUCTURE AND FUNCTION OF RESTRICTION-LIKE-ENDONUCLEASE BEARING LONG INTERSPERSED NUCLEOTIDE ELEMENTS
(2017-08-09)Long Interspersed Nucleotide Elements (LINEs) are a major group of eukaryotic transposable elements that have profoundly influenced and sculpted eukaryotic genome structure and function. LINEs replicate within the host ... -
Growth and stress response mechanisms underlying post-feeding organ regenerative growth in snakes
(2017-08-24)Snakes represent an emerging model in biological research and provide a valuable system for studying multiple extreme phenotypes unparallel to those seen in mammals. Recently, snakes have become increasingly used in studies ... -
The Herpetofauna Of The Virunga Mountains With Emphasis On Two Species of Albertine Rift Endemic Treefrogs Of The Genus Leptopelis.
(Biology, 2010-07-19)I present a short description of the biodiversity crisis, the Albertine Rift as a biodiversity hotspot, and a literature review of the taxonomy of the genus Leptopelis. I then present a list of the reptiles and anurans ... -
How Herbivores Affect Plant Growth, Community Structure And Litter Decomposition In Alaskan Tundra: Implications For Responses To Climate Change
(Biology, 2008-09-17)Increasing atmospheric carbon dioxide (CO2) concentrations have caused higher air temperatures in the Arctic. Because arctic organisms are temperature limited, warmer conditions lead to higher decomposition and nutrient ... -
How Soil Nutrient Availability Affects Plant Sexual Reproduction And Seedling Recruitment In Alaskan Dry Heath Tundra: Implications For Response To Climate Change
(Biology, 2009-09-16)The harsh growing conditions of the arctic biome, in particular low temperatures and soil nutrient availability, restrict the growth and reproduction of arctic plant species. Recent and ongoing changes in climate are ... -
Human Anatomy Lab Manual
(Mavs Open Press, 2018)This is a lab manual for a college-level human anatomy course. Mastery of anatomy requires a fair amount of memorization and recall skills. The activities in this manual encourage students to engage with new vocabulary in ... -
