Understanding and estimating effective population size for practical application in marine species management.
Effective population size (N(e)) determines the strength of genetic drift in a population and has long been recognized as an important parameter for evaluating conservation status and threats toExpand

Prospects for nuclear gene phylogeography
In phylogeography, an empirical focus on gene lineages enables the history of population processes to be inferred from the simultaneous analysis of temporal and spatial patterns. Rapidly evolvingExpand

Single-step species identification of bivalve larvae using multiplex polymerase chain reaction
Abstract One of the biggest obstacles to studying recruitment variation in marine bivalves is the need to collect and process large numbers of plankton samples. Larval bivalves are notoriouslyExpand

Defining Loci in Restriction-Based Reduced Representation Genomic Data from Nonmodel Species: Sources of Bias and Diagnostics for Optimal Clustering
Next generation sequencing holds great promise for applications of phylogeography, landscape genetics, and population genomics in wild populations of nonmodel species, but the robustness ofExpand

Isolation by distance in the eastern oyster, Crassostrea virginica, in Chesapeake Bay.
Intensive efforts are underway to restore depleted stocks of Crassostrea virginica in Chesapeake Bay. However, the extent of gene flow among local populations, an important force mediating theExpand

PREDICTING NUCLEAR GENE COALESCENCE FROM MITOCHONDRIAL DATA: THE THREE-TIMES RULE
Abstract Coalescence theory predicts when genetic drift at nuclear loci will result in fixation of sequence differences to produce monophyletic gene trees. However, the theory is difficult to applyExpand

NATURALIZED POPULATIONS OF OYSTERS, CRASSOSTREA GIGAS ALONG THE SOUTH AFRICAN COAST: DISTRIBUTION, ABUNDANCE AND POPULATION STRUCTURE
Abstract The Japanese oyster Crassostrea gigas forms the mainstay of the South African oyster farming industry. Despite having been cultured along the South African coast for 30 years, this is theExpand

GENETIC DIVERSITY AND EXPANDING NONINDIGENOUS RANGE OF THE RHIZOCEPHALAN LOXOTHYLACUS PANOPAEI PARASITIZING MUD CRABS IN THE WESTERN NORTH ATLANTIC
Nonindigenous parasite introductions and range expansions have become a major concern because of their potential to restructure communities and impact fisheries. Molecular markers provide anExpand

Cryptic diversity and comparative phylogeography of the estuarine copepod Acartia tonsa on the US Atlantic coast
Unexpectedly strong geographic structures in many cosmopolitan species of marine holoplankton challenge the traditional view of their unrestrained dispersal and presumably high gene flow. WeExpand

Genetic relationships of the marine invasive crab parasite Loxothylacus panopaei: an analysis of DNA sequence variation, host specificity, and distributional range
Host specificity is a key variable of the niche breath of parasites that can be an important determinant of a parasite’s ability to invade new areas. There is increasing evidence that many parasiteExpand
