Diversity And Distribution Of Diatom Endosymbionts In Amphistegina Spp. (Foraminifera) Based On Molecular And Morphological Techniques, Kwasi H. Barnes
Diversity And Distribution Of Diatom Endosymbionts In Amphistegina Spp. (Foraminifera) Based On Molecular And Morphological Techniques, Kwasi H. Barnes
USF Tampa Graduate Theses and Dissertations
Diatoms associated with foraminifers of the genus Amphistegina were assessed using a combination of morphological and molecular techniques. These included: 1) microscopic identification of diatoms cultured from the host, 2) sequencing of portions of the small subunit of the ribosomal RNA gene (18S) and the large subunit of the ribulose-1,5-bisphosphate carboxylase/oxygenase [i.e., RubisCO] gene (rbcL) from DNA extracted directly from the Amphistegina hosts and also from diatoms cultured from these hosts, and 3) denaturing gradient gel electrophoresis (DGGE) profiles of rbcL and internal transcribed spacer 1 (ITS1) PCR amplicons from DNA extracted directly from …
Transcriptome Analysis Of Sea Lamprey Embryogenesis, Zakary Ilya Yermolenko
Transcriptome Analysis Of Sea Lamprey Embryogenesis, Zakary Ilya Yermolenko
Seton Hall University Dissertations and Theses (ETDs)
The sea lamprey (Petromyzon marinus) has survived throughout evolution for hundreds of millions of years. It is considered an invasive species to the Great Lakes that has caused dramatic changes in the ecosystem for fish communities resulting in the collapse of a fishing industry that was previously valued at billions of dollars. Successful management of the sea lamprey is essential to a sustainable fishing industry and biodiversity. Therefore sea lamprey embryos were studied at various stages of development by growing them in a simulated habitat. RNAs from adult female ovaries and embryos at different time points during embryogenesis …
Phylogenetic Analysis Of Blacknose Dace (Rhinichthys) In West Virginia Streams, Samantha Taylor
Phylogenetic Analysis Of Blacknose Dace (Rhinichthys) In West Virginia Streams, Samantha Taylor
Theses, Dissertations and Capstones
Blacknose dace (Rhinichthys) are one of the most common cyprinid fishes in eastern North America. They also have been a topic of debate for over 30 years because morphology-based systematics has failed to clearly define their taxa. Taxonomists classify the complex into two species and one subspecies: the eastern form, R. atratulus atratulus; and the western form R. obtusus obtusus, and southern form R. obtusus meleagris. This research uses the mitochondrial cytochrome b gene and genomic RAG 2 gene in a phylogenetic analysis to help clarify species relations according to differences between each current species. Maps have been created to …
