The anatomical and phylogenetic nature of the first mitochondrial ancestor
(2020-01-21)Mitochondria are cell organelles that evolved by endosymbiosis. Even though the nature of the last mitochondrial common ancestor is well constrained, little is known about the nature of the first mitochondrial common ... -
Common Structure Among Maximum Agreement Forests of Phylogenetic Trees
(2021-09-01)Reconciling sets of phylogenetic trees has become a problem of particular interest in both theoretical computer science and bioinformatics. The use of the maximum agreement forest as a tool by which to attain insight into ... -
A COMPARISON OF METHODS FOR CONSTRUCTING CONFIDENCE SETS OF PHYLOGENETIC TREES USING MAXIMUM LIKELIHOOD
(2021-04-07)This thesis compares six phylogenetic tests, or equivalently, methods for con- structing confidence sets of phylogenetic trees : the Kishino-Hasegawa (KH) test statistic, Shimodaira–Hasegawa (SH), two versions of the ... -
Exploring the Phylogenetic Diversity of Phagotrophic Euglenids
(2021-05-05)Euglenids are a widespread, complex group of flagellated, single-celled eukaryotes. The majority of described species are phototrophic forms, yet a large portion of the phylogenetic diversity is composed of phagotrophs, ... -
PHYLOGENOMIC APPROACHES TO THE ANALYSIS OF FUNCTIONAL DIVERGENCE AND SUBCELLULAR LOCALIZATION
(2012-03-02)With rapid advances in sequencing technologies and precipitous decreases in cost, public sequence databases have increased in size apace. However, experimental characterization of novel genes and their products remains ... -
Sampling Discrete Combinatorial Spaces in Phylogenetics
(2015-04-28)Phylogenetics is the study and identification of evolutionary structure, and phylogeneticists often present evolutionary inferences as leaf-labelled trees. We investigate the combinatorial nature of phylogenetic tree ... -
Transforming the eukaryotic tree of life through isolation, characterisation, and phylogenetics of novel free-living protists
(2022-12-16)The overwhelming majority of eukaryotic diversity is microbial and protistan. Major new groups are discovered nearly every year up to this day. I established several dozen cultures of heterotrophic protists comprised of ...
