A recent taxonomic revision of wandering albatross elevated each of the four subspecies to species. We used mitochondrial DNA and nine microsatellite markers to study the phylogenetic relationships of three species (Diomedea antipodensis, D. exulans and D. gibsoni) in the wandering albatross complex. A small number of samples from a fourth species, D. dabbenena, were analysed using mitochondrial DNA only. Mitochondrial DNA sequence analyses indicated the presence of three distinct groups within… Expand
Piecing together the global population puzzle of wandering albatrosses: genetic analysis of the Amsterdam albatross Diomedea amsterdamensis
TLDR
Low levels of genetic variation in Amsterdam albatross likely resulted, at least in part, from a population bottleneck, and conservation efforts in the area are strongly urged, especially in relation to long line fisheries and other threats such as disease and introduced predators. Expand
Phylogeography and genetic structure of two Patagonian shag species (Aves: Phalacrocoracidae).
TLDR
The hypothesis that non-physical barriers are important drivers of the genetic and phylogeographic structure in seabirds, and also that physical barriers constitute effective but not absolute impediments to gene flow, is supported. Expand
Population biology of the wandering albatross (Diomedea exulans) in the Crozet and Kerguelen archipelagos, southern Indian Ocean, approached through genetic and demographic methods
TLDR
Although males are more philopatric than females, genetic differentiation among colonies was not higher in males and no significant genetic differentiation between sexes was observed, and it is proposed that the population from Crozet and that from Kerguelen are considered as distinct management units. Expand
Surviving with low genetic diversity: the case of albatrosses
TLDR
Simulations supported the hypothesis that genetic diversity in albatrosses was already depleted prior to their divergence, and appear to challenge the classical view about the negative consequences of genetic depletion on species survival. Expand
Conservation genetics of the endangered eastern freshwater cod, Maccullochella ikei
TLDR
This thesis aims to fill critical gaps in the knowledge of M. ikei by examining genetic diversity over a broad range of evolutionary scales and suggests that ancestral cod crossed the Great Dividing Range around 1 million years ago and subsequently colonised east coast drainages during Pleistocene glacial periods. Expand
Inferring the ancient population structure of the vulnerable albatross Phoebastria albatrus, combining ancient DNA, stable isotope, and morphometric analyses of archaeological samples
TLDR
The results suggest that the birds at the present two breeding regions (Torishima in the Izu Islands and two islets of the Senkaku Islands) are descended from these two ancient populations, and that reevaluation of the status and conservation strategy for the species is required. Expand
Greater flamingo colonies around the Mediterranean form a single interbreeding population and share a common history
TLDR
Analysis of both mitochondrial DNA and microsatellites indicated that populations have undergone a bottleneck followed by rapid growth and expansion, and relevance to conservation and management of the species is discussed. Expand
Unexpectedly high genetic diversity of mtDNA control region through severe bottleneck in vulnerable albatross Phoebastria albatrus
TLDR
The present population of the short-tailed albatross seems not to be affected by inbreeding depression through a severe bottleneck, and the conservation and expansion of their breeding grounds, and effective protection from bycatch mortality in foraging areas are important for the future survival of this species. Expand
Population divergence and gene flow in an endangered and highly mobile seabird
TLDR
The lack of population structure between extirpated Molokai birds and modern birds on Lanai indicates that there was substantial gene flow between these populations and that petrels may be able to overcome barriers to dispersal prior to completeextirpation. Expand
Morphological and genomic comparisons of Hawaiian and Japanese Black-footed Albatrosses (Phoebastria nigripes) using double digest RADseq: implications for conservation
TLDR
Using museum specimens, patterns suggest that the Hawaiian and Japanese populations exhibit small but significant differences and should be considered separate management units, although the evolutionary and adaptive consequences of this differentiation remain to be identified. Expand

Genetic structure, conservation genetics and evidence of speciation by range expansion in shy and white‐capped albatrosses
TLDR
High levels of genetic structuring were found and many unshared alleles between the species were detected, which provide strong evidence against any contemporary gene flow between them, and upheld the hypothesis that shy albatrosses were founded by white‐capped albatosses. Expand
Population Changes and Biology of the Wandering Albatross Diomedea exulans gibsoni at the Auckland Islands
TLDR
This is the first reliable estimate of the size of the population of Diomedea exulans gibsoni, endemic to the Auckland Islands in the New Zealand subantarctic, and compared with other subspecies of Wandering Albatross. Expand
Separating the Tristan Albatross and the Wandering Albatross Using Morphometric Measurements
TLDR
The first detailed morphometric measurements of the male and female of the Tristan Albatross are presented, which are useful to allow fishery observers to correctly identify albatrosses killed on longlines in the Atlantic Ocean. Expand
Phylogeography of shy and white‐capped albatrosses inferred from mitochondrial DNA sequences: implications for population history and taxonomy
TLDR
Phylogeographic analyses indicated unambiguous genetic structuring between shy and white‐capped albatrosses, thus confirming the demographic isolation of the species, but showed little to no structuring within each species. Expand

TLDR
Genetic analyses support the current classification of T. impavida as being distinct from T. melanophris, but would also suggest splitting T.impavida into two groups: Falkland Islands, and Diego Ramirez/South Georgia/Kerguelen. Expand

Using phylogeographic analyses of gene trees to test species status and processes
TLDR
By using gene trees in this manner, species can be identified with objective, a priori criteria with an inference procedure that automatically yields much insight into the process of speciation. Expand
Body size effects and rates of cytochrome b evolution in tube-nosed seabirds.
TLDR
The results support previous findings of body size effects and show that this effect can be significant even within a single avian order, and suggests that even lineage-specific molecular clocks may not be tenable if calibrations involve taxa with different metabolic rates. Expand
