Journal ArticleDOI
Site-specific genetic divergence in parallel hybrid zones suggests nonallopatric evolution of reproductive barriers.
TL;DR: In this article, the authors analyzed gene flow over two hybrid zones separating ecotypes of Littorina saxatilis to test the expectation that neutral genetic markers will show site-specific differences if barriers have evolved in situ.
Journal ArticleDOI
Life on the margin: genetic isolation and diversity loss in a peripheral marine ecosystem, the Baltic Sea.
Kerstin Johannesson,Carl André +1 more
TL;DR: Despite the short geological history of the Baltic Sea, populations inhabiting the Baltic have evolved substantially different from Atlantic populations, probably as a consequence of isolation and bottlenecks, as well as selection on adaptive traits.
Journal ArticleDOI
The paradox of Rockall: why is a brooding gastropod ( Littorina saxatilis ) more widespread than one having a planktonic larval dispersal stage ( L. littorea )?
TL;DR: To show that this may be true the detailed geographical distribution of two intertidal gastropod species with contrasting modes of development is presented and further support from the literature for this hypothesis is discussed.
Journal ArticleDOI

TL;DR: It is argued that the Baltic Sea can serve as a time machine to study consequences and mitigation of future coastal perturbations, due to its unique combination of an early history of multistressor disturbance and ecosystem deterioration and early implementation of cross-border environmental management to address these problems.
