Acclimation, Long-Term Repeatability, And Phenotypic Correlations Of Aerobic Metabolic Traits In The Gulf Killifish, Fundulus Grandis, Jessica E. Reemeyer
Acclimation, Long-Term Repeatability, And Phenotypic Correlations Of Aerobic Metabolic Traits In The Gulf Killifish, Fundulus Grandis, Jessica E. Reemeyer
University of New Orleans Theses and Dissertations
This research examined the effects of acclimation to lowered salinity, elevated temperature, and hypoxia on aerobic metabolism of the Gulf killifish, Fundulus grandis, a common estuarine resident of the Gulf of Mexico. Standard metabolic rate (SMR), maximum metabolic rate (MMR), absolute aerobic scope (AAS), and critical oxygen tension (Pcrit) were each influenced by one or more acclimation treatments. Assessing the consistency of these traits measured in the same individuals over time, all were found to be significantly repeatable with no indication that the repeatability of any traits was affected by acclimation conditions. Significant correlations were found between …
Validation Of Antibodies Used To Study Hypoxia Inducible Factors In Two Species Of Fundulus, Jenna D. Hill
Validation Of Antibodies Used To Study Hypoxia Inducible Factors In Two Species Of Fundulus, Jenna D. Hill
University of New Orleans Theses and Dissertations
Hypoxia inducible factors (HIFs) are transcription factors and the master regulators of oxygen-dependent gene expression in animals. The focus of this thesis is the distribution of HIF protein in tissues of the fish Fundulus heteroclitus and F. grandis, two widespread species that occur in naturally hypoxic waters. Polyclonal antibodies against HIF-1α, HIF-2α, and HIF-3α were tested on proteins made in vitro and on extracts made from several tissues of normoxic and hypoxic fish. Antibodies against HIF-1α and 3α bound specifically to full length protein made in vitro, and produced bands on western blots of nuclear extracts of near …
