Mitochondrial and nuclear DNA analyses reveal fine scale geographic structure in bottlenose dolphins (Tursiops truncatus) in the Gulf of Mexico
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.
Genetic analysis of sympatric morphotypes of common dolphins (genus Delphinus)
It is indicated that although sympatric, these populations of common dolphin are reproductively isolated from one another and may represent separate species in the Northeast Pacific.
Variability of the mitochondrial control region in populations of the harbour porpoise, Phocoena, on interoceanic and regional scales
A portion of the mitochondrial DNA control region was amplified and sequenced to characterize the amount of genetic variation within harbour porpoise populations in the Northeast Pacific, North Atlantic, and Black Sea and the utility of the control region to discriminate among putative populations along the west coast of North America was investigated.
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 significance…
Restricted dispersal in a continuously distributed marine species: common bottlenose dolphins Tursiops truncatus in coastal waters of the western North Atlantic
The genetic results reject the hypothesis of a single stock of coastal bottlenose dolphins put forth after the 1987–1988 epizootic that caused a large‐scale die‐off of dolphins and suggest instead the disease vector was transferred from one population to the next as a result of seasonal migratory movements of some populations.
Phylogenetic relationships among the true porpoises (Cetacea:Phocoenidae).
Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea:…
IMPROVING MANAGEMENT OF OVERLAPPING BOTTLENOSE DOLPHIN ECOTYPES THROUGH SPATIAL ANALYSIS AND GENETICS
The results indicate that a conservative abundance estimate for the coastal ecotype could be generated from surveys of bottlenose dolphins within 7.5 km of shore, and a statistically significant break in ecotype distribution at 34 km from shore is found.

The data indicate that the orders Ceriantharia and Antipatharia are highly divergent, and a phylogenetic reconstruction provides support for the two-subclass system of the class Anthozoa (Hexacorallia and Octocor allia).
