  abstract = {{D}espite the openness of the oceanic environment, limited dispersal and tight social structure often induce genetic structuring in marine organisms, even in large animals such as cetaceans. {I}n the bottlenose dolphin, mitochondrial and nuclear {DNA} analyses have revealed the existence of genetic differentiation between pelagic (or offshore) and coastal (or nearshore) ecotypes in the western {N}orth {A}tlantic, as well as between coastal populations. {B}ecause previous studies concentrated on continental margins, we analysed the population structure of bottlenose dolphins in two of the most isolated archipelagos of the {N}orth {A}tlantic: the {A}zores and {M}adeira. {W}e analysed 112 samples collected on live animals in the two archipelagos, and nine samples collected on stranded animals in {M}adeira and mainland {P}ortugal. {G}enetic analyses consisted in molecular sexing, sequencing of part of the mitochondrial hyper-variable region, and screening of ten microsatellite loci. {W}e predicted that: (1) there is at least one pelagic and one or more coastal populations in each archipelago; (2) populations are differentiated between and possibly within archipelagos. {C}ontrary to these predictions, results indicated a lack of population structure in the study area. {I}n addition, comparison with published sequences revealed that the samples from the {A}zores and {M}adeira were not significantly differentiated from samples of the pelagic population of the western {N}orth {A}tlantic. {T}hus, bottlenose dolphins occurring in the pelagic waters of the {N}orth {A}tlantic belong to a large oceanic population, which should be regarded as a single conservation unit. {U}nlike what is known for coastal populations, oceanic bottlenose dolphins are able to maintain high levels of gene flow.},
