“…New Zealand, Tristan da Cunha and Amsterdam Islands are good examples. The latter two islands are more northerly, albeit not sub-Antarctic, islands where populations or sister taxa of albatrosses (Tristan and Amsterdam), petrels (Spectacled and White-faced Storm (Pelogodroma marina)) and penguins (Rockhopper) have become isolated from southern populations (Banks et al 2006;Jouventin et al 2006;Baker et al 2009;De Dinechin et al 2009;Techow et al 2009;Rains et al 2011;Silva et al 2015). For each of these five species, the differences are sufficient that they have been given species or subspecies status.…”

“…Other families including Laridae (gulls) and Sternidae (terns) are found in the Southern Ocean; however, population genetic data are limited and therefore not included in this review. All of these species are capable of long-distance dispersal; however, many are highly philopatric (Coulson 2002;Cristofari et al 2015;Silva et al 2015), often returning to within several hundred metres of their natal site and creating a gene flow paradox. Gene flow is examined Figure 1.…”

Genetic signatures of historical, behavioural and environmental processes are evident in contemporary seabird populations. Molecular markers have allowed us to determine historical patterns of gene flow, relationships among taxa, and contemporary dispersal barriers. The Southern Ocean contains a number of small, isolated islands that are home to four families of seabirds: albatrosses, petrels, penguins and skuas, which have been the focus of a number of population genetic studies. While capable of travelling large distances, many seabirds have restricted dispersal and exhibit high levels of population structure; typically in northern areas and areas with high endemism (e.g. New Zealand). We reviewed 29 studies of 25 Southern Ocean seabird species comparing biogeographic patterns, glacial history and barriers to gene flow, especially at-sea distribution and ocean currents. Despite diversity in behaviour and life history, our review demonstrates that population genetic structure of the seabirds corresponds to the same barriers. For penguins, currents are the major impediment to dispersal whereas at-sea distribution and island location influence population structure for many seabirds with genetically distinct populations on islands at the periphery of their range. As environmental conditions change, it will become more important to assess how seabirds respond and how these changes influence both dispersal and population structure. It is particularly important as a disproportionately high number of Southern Ocean seabirds are threatened or near threatened. Future studies need to focus on adaptive genetic markers, range-wide comprehensive sampling, influence of behaviour on genetic structure and lesser studied seabirds such as terns and cormorants.

DNA barcoding a unique avifauna: an important tool for evolution, systematics and conservation

et al. 2019

BackgroundDNA barcoding utilises a standardised region of the cytochrome c oxidase I (COI) gene to identify specimens to the species level. It has proven to be an effective tool for identification of avian samples. The unique island avifauna of New Zealand is taxonomically and evolutionarily distinct. We analysed COI sequence data in order to determine if DNA barcoding could accurately identify New Zealand birds.ResultsWe sequenced 928 specimens from 180 species. Additional Genbank sequences expanded the dataset to 1416 sequences from 211 of the estimated 236 New Zealand species. Furthermore, to improve the assessment of genetic variation in non-endemic species, and to assess the overall accuracy of our approach, sequences from 404 specimens collected outside of New Zealand were also included in our analyses. Of the 191 species represented by multiple sequences, 88.5% could be successfully identified by their DNA barcodes. This is likely a conservative estimate of the power of DNA barcoding in New Zealand, given our extensive geographic sampling. The majority of the 13 groups that could not be distinguished contain recently diverged taxa, indicating incomplete lineage sorting and in some cases hybridisation. In contrast, 16 species showed evidence of distinct intra-species lineages, some of these corresponding to recognised subspecies. For species identification purposes a character-based method was more successful than distance and phylogenetic tree-based methods.ConclusionsDNA barcodes accurately identify most New Zealand bird species. However, low levels of COI sequence divergence in some recently diverged taxa limit the identification power of DNA barcoding. A small number of currently recognised species would benefit from further systematic investigations. The reference database and analysis presented will provide valuable insights into the evolution, systematics and conservation of New Zealand birds.Electronic supplementary materialThe online version of this article (10.1186/s12862-019-1346-y) contains supplementary material, which is available to authorized users.

Identifying mechanisms of genetic differentiation among populations in vagile species: historical factors dominate genetic differentiation in seabirds

et al. 2020

View full text Add to dashboard Cite

Elucidating the factors underlying the origin and maintenance of genetic variation among populations is crucial for our understanding of their ecology and evolution, and also to help identify conservation priorities. While intrinsic movement has been hypothesized as the major determinant of population genetic structuring in abundant vagile species, growing evidence indicates that vagility does not always predict genetic differentiation. However, identifying the determinants of genetic structuring can be challenging, and these are largely unknown for most vagile species. Although, in principle, levels of gene flow can be inferred from neutral allele frequency divergence among populations, underlying assumptions may be unrealistic. Moreover, molecular studies have suggested that contemporary gene flow has often not overridden historical influences on population genetic structure, which indicates potential inadequacies of any interpretations that fail to consider the influence of history in shaping that structure. This exhaustive review of the theoretical and empirical literature investigates the determinants of population genetic differentiation using seabirds as a model system for vagile taxa. Seabirds provide a tractable group within which to identify the determinants of genetic differentiation, given their widespread distribution in marine habitats and an abundance of ecological and genetic studies conducted on this group. Herein we evaluate mitochondrial DNA (mtDNA) variation in 73 seabird species. Lack of mutation-drift equilibrium observed in 19% of species coincided with lower estimates of genetic differentiation, suggesting that dynamic demographic histories can often lead to erroneous interpretations of contemporary gene flow, even in vagile species. Presence of land across the species sampling range, or sampling of breeding colonies representing ice-free Pleistocene refuge zones, appear to be associated with genetic differentiation in Tropical and Southern Temperate species, respectively, indicating that long-term barriers and persistence of populations are important for their genetic structuring. Conversely, biotic factors commonly considered to influence population genetic structure, such as spatial segregation during foraging, were inconsistently associated with population genetic differentiation. In light of these results, we recommend that genetic studies should consider potential historical events when identifying determinants of genetic differentiation among populations to avoid overestimating the role of contemporary factors, even for highly vagile taxa.
