Avian phylogeny and divergence times based on mitogenomic sequences : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Genetics, Institute of Molecular BioSciences, Massey University, Palmerston North, New Zealand

A revised annotation of avian and reptile mt genomes has been carried out, which improves consistency of labeling gene start and stop positions and a number of conserved patterns and interesting differences identified.

Four new avian mitochondrial genomes help get to basic evolutionary questions in the late cretaceous.

It is found, as with other animal mitochondrial genomes, that RY-coding is helpful in adjusting for biases between pyrimidines and between purines, and the root occurs between paleognath and neognath birds.

Complete mitochondrial genome sequence of an Australian little penguin (Eudyptula minor novaehollandia, J.R. Forster, 1781)

The complete mitochondrial genome of an Australian little penguin (Eudyptula minor novaehollandia) has been reported, and the mitogenome sequence has been found to be circular, and 17,608 bp in length.

Complete sequence and gene organization of the mitochondrial genome of scaly-sided merganser (Mergus squamatus) and phylogeny of some Anatidae species

The complete mitochondrial genome and phylogenetic of M. squamatus are studied and Lophodytes cucullatus and Mergullus albellus are supported to be members of the genus Mergus and the phylogenetic relationships among ten Anatidae species are discussed.

The Complete Mitochondrial Genome of Bean Goose (Anser fabalis) and Implications for Anseriformes Taxonomy

The complete mtDNA of Bean goose is determined, which is 16,688 bp long and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region, which supports the classification of them into four major branches: Anatinae, Anserinee, Dendrocygninae and Anseranatidae.

New view on the organization and evolution of Palaeognathae mitogenomes poses the question on the ancestral gene rearrangement in Aves

The duplicated control regions with adjacent genes are more common in avian mitochondrial genomes than it was previously thought and could increase effectiveness of replication and transcription as well as the number of replicating mitogenomes per organelle.

A phylogeny of extant penguins (Aves: Sphenisciformes) combining morphology and mitochondrial sequences

Molecular and morphological results indicated that the most significant problem in the phylogeny of extant penguins is rooting the ingroup, and the mutual interaction of molecular and Morphological data decreases the ambiguity regarding the placement of the root, and provides a resolved, relatively well‐supported phylogeny.

Complete Mitochondrial Genome Sequences and the Phylogeny of Cranes (Gruiformes: Gruidae)

Bayesian estimates of divergence dates from mitochondrial DNA sequences suggest that balearicines and gruines separated in the late Oligocene and that radiations of living species within these clades took place in the Neogene.

Interordinal relationships of birds and other reptiles based on whole mitochondrial genomes.

Support is found for a sister relationship between turtles and a bird/crocodilian clade, and for rejecting both the Haemothermia hypothesis and the placement of turtles as basal within the phylogenetic tree for amniote animals.

The mitochondrial genomes of the iguana (Iguana iguana) and the caiman (Caiman crocodylus): implications for amniote phylogeny

The complete mitochondrial genomes of two reptiles, the common iguana and the caiman, were sequenced in order to investigate phylogenetic questions of tetrapod evolution and corroborated the view that turtles are at the base of the bird–crocodile branch.

Mitochondrial genomic rearrangements in songbirds.

The results suggest that this derived arrangement cannot be used to distinguish between suboscine and oscine passerines, as it has multiple origins both within Passeriformes and within birds as a whole.

Mammalian mitogenomic relationships and the root of the eutherian tree

A mitogenomic study based on the set of protein-coding genes from complete mt genomes of 60 mammalian species finds that the previously unrepresented order Dermoptera (flying lemurs) fell within Primates as the sister group of Anthropoidea, making Primates paraphyletic.

The early history of modern birds inferred from DNA sequences of nuclear and mitochondrial ribosomal genes.

Phylogenetic results suggest that the earliest neornithines were heavy-bodied, ground-dwelling, nonmarine birds, and this inference provides a possible explanation for the large gap in the early fossil record of birds.

Most of the major ratite lineages fit the vicariance biogeography hypothesis, the exceptions being the ostrich and the kiwi, which require dispersal to explain their present distribution.

Analyses of mitochondrial DNA nest ratite birds within the Neognathae: supporting a neotenous origin of ratite morphological characters

The findings suggest that the morphological characteristics of the ratite species are secondarily acquired, probably through neoteny and that the ratites are descendants of flying, neognathous ancestors.

We have determined the nucleotide sequence of the entire mitochondrial control region (CR) of the Adélie penguin (Pygoscelis adeliae) from Antarctica. Like in most other birds, this CR region is

Rooting a phylogeny with homologous genes on opposite sex chromosomes (gametologs): a case study using avian CHD.

The CHD analyses calibrated with avian fossil dates are estimated at 123 MYA, suggesting an early differentiation of sex chromosomes that predates most extant avian orders and a faster rate of change in male-linked CHD-Z sequences, in agreement with the notion of male-driven evolution.

The complete nucleotide sequence of the mitochondrial DNA of the fin whale,Balaenoptera physalus

A comparison between the cytochromeb gene of the fin whale and cy tochromeb sequences in the literature, including dolphin (Stenella) sequences, identified the cetaceans as monophyletic and the artiodactyls as their closest relatives.
