The Interplay Of Environmental Stressors On The Life History Traits In Daphnia lumholtzi
Leonard-Whittington, Deirdre (Biology, 2014-12)In natural environments, organisms face multiple stressors that threaten their persistence. Aquatic organisms respond to a change in environmental conditions by adaptively modifying the expression of traits (i.e., ... -
Protein-DNA interactions of the RLE LINE R2Bm
Rachakonda, Shalini (2020-12-07)Long interspersed elements (LINEs) are a major group of non-long terminal repeat (non-LTR) retrotransposable elements that are ubiquitous in eukaryotic genomes. These selfish genetic elements influence the structure and ... -
The evolution of complexity: tests of the ecological drivers of eye size evolution in nature
Beston, Shannon Marie; 0000-0003-0246-1567 (2019-04-29)Organisms exhibit extensive variation in eye size and structure across the animal kingdom. The long standing hypothesis is that divergent ecological selective pressures drive and maintain this variation. While multiple ... -
THE EVOLUTION OF LIFE HISTORIES AND PHENOTYPIC PLASTICITY ACROSS ENVIRONMENTAL GRADIENTS IN DAPHNIA SP.
Packer, Michelle Renee Swan; 0000-0002-6288-2606 (2020-08-11)Understanding how environmentally-induced variation ultimately leads to speciation is a main component of evolutionary ecology. This dissertation uses Daphnia in experimental and comparative studies to address several ... -
THE EVOLUTION OF NEUROSENSORY STRUCTURES: EVALUATING ECOLOGICAL DRIVERS OF BRAIN AND EYE SIZE VARIATION
Howell, Kaitlyn J; 0000-0002-3214-1225 (2022-05-18)Neurosensory structures (i.e., brain and eye size) vary extensively across taxa. The evolution of large neurosensory structures has long been an area of interest for scientists, but focus has largely been placed on ... -
The Influence Of Thermal Effluent On Life History Evolution In The Western Mosquitofish, Gambusia affinis
Boyles, Amanda M. (Biology, 2015)The evolutionary consequence of heated effluent on the Western mosquitofish, Gambusia affinis, was studied at Lake Fairfield, in Freestone County, Texas. The Lake Fairfield reservoir receives heated effluent from Luminant’s ... -
Thermal Transgenerational Plasticity and Its Effect on Competitive Ability and Consumer-Resource Dynamics in a Population of Daphnia ambigua
Holmes, Julian; 0000-0002-5148-3140 (2015-12-08)Global temperature increases are predicted to quicken in pace this century, and with them so will the likely impact on natural populations. The extent to which organisms will be able to keep pace with and adapt to these ...
