Few marine hybrid zones have been studied extensively, the major exception being the
hybrid zone between the mussels Mytilus edulis and Mytilus galloprovincialis in …

Animal fertilization is governed by the interaction (binding) of proteins on the surfaces of
sperm and egg. In many examples presented herein, fertilization proteins evolve rapidly and …

Many marine invertebrate taxa are broadcast spawners, where multiple individuals release
their gametes into the water for external fertilization, often in the presence of gametes from …

The ecological and genetic factors determining the extent of introgression between species
in secondary contact zones remain poorly understood. Here, we investigate the relative …

Seasonal environmental changes may affect the physiology of Mytilus galloprovincialis
(Lam.), an intertidal filter-feeder bivalve occurring commonly in Mediterranean and Atlantic …

While secondary contact between Mytilus edulis and Mytilus trossulus in North America
results in mosaic hybrid zone formation, both species form a hybrid swarm in the Baltic …

Proteins involved in reproduction often evolve rapidly, raising the possibility that changes in
these proteins contribute to reproductive isolation between species. We review the evidence …

In numerous species, egg chemoattractants play a critical role in guiding sperm towards
unfertilized eggs (sperm chemotaxis). Until now, the known functions of sperm chemotaxis …

Smooth-shelled blue mussels of the genus Mytilus have long been a major focus of research
because such mussels have an interesting global (antitropical or bipolar) distribution, have a …

The genetic constitution of mussels (Mytilus spp.) was studied by means of three nuclear
(Me 15/16, EF-bis, ITS) and one mtDNA (ND2-COIII) marker on a large European scale. In …
