Phylogeny-based analysis of gene clusters
Durch die Erforschung von verwandtschaftlichen Beziehungen, der Phylogenie, verschiedener Spezies erlangen wir umfassende Informationen über deren Evolution. Ein Ansatz für die Rekonstruktion phylogenetischer Szenarien oder zum Vergleich von Genomen ist die Untersuchung des Erbguts auf Ebene der …

Phylogeny and chloroplast evolution in Brassicaceae
… the possibility to make use of big data in phylogeny and evolutionary studies. Thus, we sequenced the chloroplast genomes of 80 representative species, using additional 15 reference chloroplast genomes from the NCBI database, and carried out both the phylogenetic reconstruction and the study …

Phylogeny of the Scarabaeini (Coleptera: Scarabaeidae)
The Scarabaeini comprises some 146 species of ball-rolling dung beetles belonging to the genera Pachylomerus and Scarabaeus, and Scarabaeus subgenera, Kheper, Pachysoma, Scarabaeolus, Scarabaeus and· Sceliages. Their distribution extends throughout the Afrotropical region (including Madagascar) and …

Oviraptorosauria: Morphology, Phylogeny, and Endocranial Evolution
… characters with respect to the aforementioned phylogeny. Diagnostic morphologies are found for Oviraptorosauria and the more exclusive clades, Maniraptora, Paraves, and crown birds. This study also is the first to use CT technology to divide the endocranial casts into six neuroanatomical …

A molecular phylogeny of the Microsporida
The molecular phylogenetics of the Microsporida were investigated using small subunit ribosomal RNA gene sequence data. The small subunit ribosomal RNA gene was sequenced and aligned for 27 species from 18 genera and analyzed using various eukaryotic, eubacterial, and archaebacterial sequences as …

Phylogeny and biogeography of Southern African limpets in the genus Siphonaria in the context of a global phylogeny
… species within, and contribute to, a world phylogeny for the genus and analyse geographic patterns of clades emerging from this phylogenetic reconstruction. With respect to the 'S. carbo' complex, Teske et al. (2007), using mitochondrial and nuclear sequence data on Siphonaria nigerrima, S. …

A Molecular Phylogeny of the Calypterate Diptera
… developed as a tool for eukaryotic family level phylogeny. This region was sequenced for 20 Diptera and analyzed using the computer package PAUP (Phylogenetic Analysis Using Parsimony), created by David Swofford. The trees were compared to previous analyses based on morphological characters and …

Comparative morphology and phylogeny of anomalodesmatan bivalves
Anomalodesmatans comprise a large, ancient and ecologically diverse group of marine bivalves, but are nonetheless inconspicuous in most extant shallow water communities. For various reasons, which include their present scarcity and a bewildering array of disparate morphologies, representatives of …

Phylogeny and biogeography of the toxic dinoflagellate Alexandrium
… occurrence are unknown. This thesis explores the phylogeny, taxonomy, and biogeography of Alexandrium in light of this recent expansion. Alexandrium phylogeny was reconstructed through rDNA sequence analysis and compared to traditional morphological taxonomy. Alexandrium split into two groups, …

Genome-wide microbial phylogeny reconstruction with polytomy identification
… to infer large scale multi-furcating microbial phylogeny without relying on MSA (multiple sequence alignment) is greatly needed. In this dissertation work, we present two applications, ComPhy (composite distance phylogeny) and PolyPhy (phylogeny reconstruction with polytomy identification), …

Analysis of Serology and Phylogeny in Spiroplasma Classification
… to determine the congruency between serology and phylogeny. This study examined a set of closely related strains to evaluate the level of congruency between serology and phylogeny. As a case study, the utility of maintaining serology as a character to delineate strain clusters was also …

Phylogeny and evolution of Lerista (Lygosominae, Scincidae, Squamata).
In this thesis, I investigate the phylogeny and evolution of Lerista, a clade of more than 75 species of scincid lizards, distributed in arid, semi-arid, and seasonally dry habitats throughout Australia. Among extant tetrapods, Lerista is exceptional in comprising a large number of closely-related …
