In this study we reconstruct phylogenies for deep sea amphipods from the North Atlantic in order to test hypotheses about the evolutionary mechanisms driving speciation in the deep sea. We sequenced five genes for specimens representing 21 families. Phylogenetic analyses showed incongruence between the molecular data and morphological taxonomy, with some(More)
The mechanisms by which phenotypic and genetic divergence may occur among sympatric, conspecific populations have been widely discussed but are still not well understood. Possible mechanisms include assortative mating based on morphology or variation in the reproductive behaviour of phenotypes, and both have been suggested to be relevant to the(More)
Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations,(More)
