Power for detecting genetic divergence: differences between statistical methods and marker loci
Information on statistical power is critical when planning investigations and evaluating empirical data, but actual power estimates are rarely presented in population genetic studies. We used… Expand

Phylogeography of the ocean quahog (Arctica islandica): influences of paleoclimate on genetic diversity and species range
Abstract The ocean quahog, Arctica islandica (Linnaeus, 1767), is a commercially important bivalve found on continental shelves throughout much of the North Atlantic. To assess genetic subdivision in… Expand

Biocomplexity in a highly migratory pelagic marine fish, Atlantic herring
The existence of biologically differentiated populations has been credited with a major role in conferring sustainability and in buffering overall productivity of anadromous fish population complexes… Expand

ENVIRONMENTAL CORRELATES OF POPULATION DIFFERENTIATION IN ATLANTIC HERRING
Abstract The marine environment is characterized by few physical barries, and pelagic fishes commonly show high migratory potential and low, albeit in some cases statistically significant, levels of… Expand

Detecting population structure in a high gene-flow species, Atlantic herring (Clupea harengus): direct, simultaneous evaluation of neutral vs putatively selected loci
In many marine fish species, genetic population structure is typically weak because populations are large, evolutionarily young and have a high potential for gene flow. We tested whether genetic… Expand

World-wide whale worms? A new species of Osedax from the shallow north Atlantic
We describe a new species of the remarkable whalebone-eating siboglinid worm genus, Osedax, from a whale carcass in the shallow north Atlantic, west of Sweden. Previously only recorded from deep-sea… Expand

Insights into the abundance and diversity of abyssal megafauna in a polymetallic-nodule region in the eastern Clarion-Clipperton Zone
There is growing interest in mining polymetallic nodules in the abyssal Clarion-Clipperton Zone (CCZ) in the Pacific. Nonetheless, benthic communities in this region remain poorly known. The… Expand

New Perspectives on the Ecology and Evolution of Siboglinid Tubeworms
Siboglinids are tube-dweling annelids that are important members of deep-sea chemosynthetic communities, which include hydrothermal vents, cold seeps, whale falls and reduced sediments. As adults,… Expand

Molecular Phylogeny of the Model Annelid Ophryotrocha
Annelids of the genus Ophryotrocha are small opportunistic worms commonly found in polluted and nutrient-rich habitats such as harbors. Within this small group of about 40 described taxa a large… Expand

High symbiont diversity in the bone-eating worm Osedax mucofloris from shallow whale-falls in the North Atlantic.
Osedax worms are whale-fall specialists that infiltrate whale bones with their root tissues. These are filled with endosymbiotic bacteria hypothesized to provide their hosts with nutrition by… Expand
