Advances in electronic tagging and genetic research are making it possible to discern population structure for pelagic marine predators once thought to be panmictic. However, reconciling migration patterns and gene flow to define the resolution of discrete population management units remains a major challenge, and a vital conservation priority for(More)
Porcelain crabs, genera Petrolisthes and Pachycheles, are diverse and abundant members of the eastern Pacific near-shore decapod crustacean community. Morphology-based taxonomic analyses of these crabs have determined groupings of affiliated species, but phylogenetic relationships remain unknown. We used sequence data from the mitochondrial 16S rRNA gene of(More)
Restriction site variation in mitochondrial DNA (mtDNA) of the American oyster (Crassostrea virginica) was surveyed in continuously distributed populations sampled from the Gulf of St. Lawrence, Canada, to Brownsville, Texas. mtDNA clonal diversity was high, with 82 different haplotypes revealed among 212 oysters with 13 endonucleases. The mtDNA clones(More)
Restriction-fragment length polymorphisms in mitochondrial DNA (mtDNA) were used to evaluate population-genetic structure and matriarchal phylogeny in four species of marine fishes that lack a pelagic larval stage: the catfishes Arius felis and Bagre marinus, and the toadfishes Opsanus tau and O. beta. Thirteen informative restriction enzymes were used to(More)
White Sharks (Carcharodon carcharias) in the northeastern Pacific comprise a genetically distinct population, demographically isolated from other populations in Australia/New Zealand and South Africa. Within the northeastern Pacific, mature and subadult White Sharks show strong fidelity to aggregation sites in Central California and Guadalupe Island,(More)
Structure and migration corridors in Paci®c populations of the Sword®sh Xiphius gladius, as inferred through analyses of mitochondrial DNA Abstract The sword®sh Xiphias gladius is a migratory oceanic species distributed in subtropical and temperate waters worldwide. Studies utilizing mitochondrial DNA (mtDNA) have demonstrated genetic subdivision between(More)
Juvenile white sharks (Carcharodon carcharias) spend their early years in coastal waters where they may be targeted by local fisheries or landed by-catch. Conservation of genetic resources for marine species becomes a main issue for apex predators such as sharks. We developed a protocol to extract DNA from teeth of mummified juvenile white shark heads found(More)
