Local adaptation and species segregation in two mussel (Mytilus edulis x Mytilus trossulus) hybrid zones.

Predator-induced defenses differ between sympatric Mytilus edulis and M. trossulus

This is the first study to compare defenses to predation in closely related species of Mytilus and draws attention to the role of predation in determining their distribution, abundance and co-existence. We experimentally determined whether 2 blue mussel species, Mytilus edulis and M. trossulus, that co-exist within a hybrid zone in Newfoundland, Canada, differ in their predator-induced response...

Mytilus trossulus in Northern Europe

From data on allozyme, nuclear DNA and mitochondrial DNA markers, we show that the originally North Pacific/Northwest Atlantic mussel Mytilus trossulus is widespread on North European coasts, earliM. trossuluser thought to be inhabited only by Mytilus edulis. Several local occurrences of , interspersed with a dominant M. edulis, were recorded on the North Sea, Norwegian Sea and Barents Sea coas...

THE EFFECTS OF TEMPERATURE ON THE SURVIVAL, GROWTH AND DEVELOPMENT OF LARVAE OF TWO BLUE MUSSEL SPECIES (Mytilus edulis and Mytilus trossulus) BY

Ubiquitous heteroplasmy in Mytilus spp. resulting from disruption in doubly uniparental inheritance regulation

Species within the marine mussel Mytilus edulis complex (M. edulis, M. galloprovincialis, and M. trossulus) have an unusual form of mitochondrial DNA (mtDNA) inheritance commonly referred to as doubly uniparental inheritance (DUI). With DUI, all progeny inherit mtDNA maternally (F), while male progeny also inherit mtDNA paternally (M) through their father’s sperm. Therefore, females are normall...

Temperature sensitivities of cytosolic malate dehydrogenases from native and invasive species of marine mussels (genus Mytilus): sequence-function linkages and correlations with biogeographic distribution.

The blue mussel Mytilus galloprovincialis, a native of the Mediterranean Sea, has invaded the west coast of North America in the past century, displacing the native blue mussel, Mytilus trossulus, from most of its former habitats in central and southern California. The invasive success of M. galloprovincialis is conjectured to be due, in part, to physiological adaptations that enable it to outp...
