Systematics And Comparative Genomics Of The Petaluridae (Odonata: Anisoptera), Ethan R. Tolman
Systematics And Comparative Genomics Of The Petaluridae (Odonata: Anisoptera), Ethan R. Tolman
Dissertations, Theses, and Capstone Projects
The Anisoptera (Insecta: Odonata), or dragonflies exhibit diverse life histories and diversification patterns, with the family Petaluridae standing out as particularly unique. Comprising only 11 extant species, all of which inhabit increasingly threatened fen habitats, Petaluridae are known for their longevity, which can exceed five years, semi-terrestrial lifestyle, and remarkable physical size, ranking among the largest insects on Earth. Despite the evolutionary peculiarities of this family, no previous genomic studies have investigated the Petaluridae. This work presents two high-quality genome sequences and a targeted enrichment dataset to explore the chromosome architecture of Petaluridae, identifies genomic adaptations associated with their distinctive …
Chloroplast Genome Evolution In The Klebsormidiophyceae And Streptofilum, Sarah Glass
Chloroplast Genome Evolution In The Klebsormidiophyceae And Streptofilum, Sarah Glass
Theses
The Klebsormidiophyceae are a class of green microalgae found globally in both freshwater and terrestrial habitats. Morphology-based classification schemes of this class have been shown to be insufficient, particularly due to the simple morphology of these algae, the tendency of morphology to vary in culture versus in field conditions, and rampant morphological homoplasy. Molecular studies revealing cryptic diversity have renewed interest in this group. We sequenced the complete chloroplast genomes of taxa in the Klebsormidiophyceae representing the known taxonomic breadth of this class, as well as the chloroplast genomes of three strains of Streptofilum, a recently discovered algal lineage …
Population Genomic Inference Of Ecology, Conservation, Evolution, And Demographic History Of Atlantic Seahorses And Pipefishes (Syngnathidae), Joel Thomas Boehm
Population Genomic Inference Of Ecology, Conservation, Evolution, And Demographic History Of Atlantic Seahorses And Pipefishes (Syngnathidae), Joel Thomas Boehm
Dissertations, Theses, and Capstone Projects
In the Atlantic Ocean powerful directional ocean currents can play a significant role in the formation and persistence of marine species. Syngnathidae fishes have a sparse fossil record, high morphological plasticity, and many of these species are difficult to observe in the wild, therefore they frequently lack life history information and the status of regional lineages and species designations are often obscure. In this dissertation I explore the ecology, evolution, and conservation of primarily Atlantic seahorses (Hippocampus) and pipefish (Syngnathus) in four core chapters, using differing genetic datasets ranging from mitochondrial DNA to genome-wide RAD sequences. Most Synganthids have the …
