We examined population substructure of bottlenose dolphins (Tursiops sp). in Shark Bay, Western Australia, using 10 highly polymorphic microsatellite loci, and mitochondrial DNA (mtDNA). For microsatellite analysis, 302 different animals were sampled from seven localities throughout the bay. Analysis of genetic differentiation between sampling localities showed a significant correlation between the number of migrants (Nm) calculated from FST, RST and private alleles, and distance between… Expand
A worldwide perspective on the population structure and genetic diversity of bottlenose dolphins (Tursiops truncatus) in New Zealand.
TLDR
Analysis of gene flow indicated long-distance dispersal among coastal and pelagic populations worldwide (except for those haplotypes described as inshore ecotype in the Western North Atlantic), suggesting that these populations are interconnected on an evolutionary timescale. Expand
Mitochondrial and nuclear DNA analyses reveal fine scale geographic structure in bottlenose dolphins (Tursiops truncatus) in the Gulf of Mexico
TLDR
Results presented here provide the first genetic evidence of population subdivision between the coastal Gulf of Mexico and adjacent inshore areas along the central west coast of Florida. Expand
Fine-scale genetic structure of bottlenose dolphins, Tursiops truncatus, in Atlantic coastal waters of the Iberian Peninsula
TLDR
Dolphins from southern Galicia and the Sado estuary were assigned to an individual genetic population, though nine dolphins were identified as possible migrants between putative populations as their genetic makeup did not correspond with their geographical stranding location. Expand
Patterns of population structure at microsatellite and mitochondrial DNA markers in the franciscana dolphin (Pontoporia blainvillei)
TLDR
Investigation of the population structure of the franciscana dolphin from a previously established management area revealed the existence of three genetically distinct populations in Argentina, which would comprise five distinct populations considering each of these populations as different management units. Expand
Fine‐scale genetic population structure in a mobile marine mammal: inshore bottlenose dolphins in Moreton Bay, Australia
TLDR
A complex variety of inter‐related factors including local habitat variation, differential resource use, social behaviour and learning, and anthropogenic disturbances are likely to have played a role in driving fine‐scale population structure among bottlenose dolphins in Moreton Bay. Expand
Patterns of population structure for inshore bottlenose dolphins along the eastern United States.
TLDR
It is proposed that the spatial pattern of genetic variation within the lagoon reflects both its steep longitudinal transition of climate and also its historical discontinuity and recent connection as part of Intracoastal Waterway development. Expand
Population genetic structure of common bottlenose dolphins (Tursiops truncatus) in the Adriatic Sea and contiguous regions : implications for international conservation
TLDR
Indication of a fine-scale population structure across the Adriatic Sea is a factor to be carefully considered in the emerging marine management scenario set by the implementation of the EU Marine Strategy Framework Directive (2008/56/CE), particularly when it comes to assessing and managing direct mortality caused by human activities. Expand
High gene flow in oceanic bottlenose dolphins (Tursiops truncatus) of the North Atlantic
TLDR
Bottlenose dolphins occurring in the pelagic waters of the North Atlantic belong to a large oceanic population, which should be regarded as a single conservation unit, and unlike what is known for coastal populations, oceanic bottlenose dolphin are able to maintain high levels of gene flow. Expand
High genetic structure and low mitochondrial diversity in bottlenose dolphins of the Archipelago of Bocas del Toro, Panama: A population at risk?
TLDR
The results suggest that the conservation status of bottlenose dolphins in Bocas del Toro should be elevated to ‘endangered’ at the national level, as a precautionary measure while population and viability estimates are conducted. Expand
Hierarchical metapopulation structure in a highly mobile marine predator: the southern Australian coastal bottlenose dolphin (Tursiops cf. australis)
TLDR
A hierarchical metapopulation structure was revealed along southern Australia, with at least six genetic populations occurring between Esperance, WA and southern Tasmania and previously identified Victorian/Tasmanian populations. Expand

Microsatellite genetic distances between oceanic populations of the humpback whale (Megaptera novaeangliae).
TLDR
Allelic diversity is a little greater in the two Antarctic samples, probably indicating historically greater population sizes, while unbiased Rst (URst) is currently the most reliable statistic, probably because, unlike the other methods, it allows for unequal sample sizes. Expand
Population structure and seasonal movements of narwhals, Monodon monoceros, determined from mtDNA analysis
TLDR
Heterogeneity within a presumed single breeding ground suggests mixing of pods with different haplotypic composition, and isolation, even between geographically close areas, as well as fidelity to specific summer and autumn feeding grounds. Expand

TLDR
The population structure of harbour porpoises from British and adjacent waters was studied by examining variability in a 200 bp (base pair) section of the control region of mitochondrial DNA (mtDNA) extracted from 327 animals, suggesting that males disperse more than females. Expand
Phylogeography and population history of Atlantic mackerel (Scomber scombrus L.): a genealogical approach reveals genetic structuring among the eastern Atlantic stocks
TLDR
In the eastern Atlantic, historical population range expansion, presumably in connection with recolonization of northern areas after the last glaciation, is suggested to be the main factor determining mtDNA lineage distribution. Expand
ISOLATION BY DISTANCE IN THE ATLANTIC COD, GADUS MORHUA, AT LARGE AND SMALL GEOGRAPHIC SCALES
TLDR
The correlation between gene flow and distance detected in G. morhua at small and large spatial scales suggests that dispersal distances and effective population sizes are much smaller than predicted for the species and that the recent age of populations, rather than extensive gene flow, may be responsible for its weak population structure.

Genetic structure of harbour porpoise Phocoena phocoena populations in the northwest Atlantic based on mitochondrial and nuclear markers
The harbour porpoise, Phocoena phocoena, experiences high levels of nonnatural mortality owing to interactions with commercial fisheries throughout its range. To accurately evaluate the significanceExpand
Microsatellites in the bottlenose dolphin Tursiops truncatus
TLDR
Five primer sets successfully amplified the target sequence and showed high levels of polymorphism in the bottlenose dolphin, and the utility of the primer sets for the amplification of microsatellite regions in four other cetacean species is tested. Expand
Coastal bottlenose dolphins from southeastern Australia are Tursiops aduncus according to sequences of the mitochondrial DNA control region
TLDR
The results strongly indicated that these two bottlenose dolphin populations from southeastern Australia belong to 2: aduncus, extending the range of the species to subtropical waters of the Western South Pacific Ocean. Expand
Analysis of the genetic structure of European eel (Anguilla anguilla) using microsatellite DNA and mtDNA markers
TLDR
The paradigm that the European eel constitutes a panmictic population becomes difficult to maintain because of the weak differentiation typical for marine species and the limitations of the data, given the results should be interpreted with caution. Expand
Low genetic variation among killer whales (Orcinus orca) in the eastern north Pacific and genetic differentiation between foraging specialists.
TLDR
Low levels of genetic dispersal between foraging specialists and a pattern of genetic differentiation consistent with matrifocal population structure and small effective population size are suggested. Expand
