Comparisons among fossil Atlantic faunas show that amphi-Atlantic distributions became established in the Middle Pliocene, and that all represent westward expansions of European taxa to North America, no American taxa spread eastward to Europe without human assistance.
A marginal habitat, but not a sink: Ecological genetics reveal a diversification hotspot for marine invertebrates in the brackish Baltic Sea
The results indicate that the Baltic Sea should be considered a diversification hotspot: the diversity of genetic patterns points towards independent trajectories in the Baltic compared to the North Sea, and limited evidence is found for the traditional scenario of the Baltic sea as a population sink with lower diversity and strong gene flow.
How did Mya arenaria (Mollusca; Bivalvia) repopulate European waters in mediaeval times?
During the Pleistocene, the coastal marine bivalve mollusc Mya arenaria became extinct in NW Europe. The species survived in Northern America. Radiocarbon dating of shells found in Denmark, The
A new ΔR value for the southern North Sea and its application in coastal research
Abstract Accelerator mass spectrometry (AMS) radiocarbon (14C) dating of Cerastoderma edule (Linnaeus 1767) and Mytilus edulis (Linnaeus 1758) shells sampled in AD 1889 near the island of Wangerooge
Reconstructing Bioinvasion Dynamics Through Micropaleontologic Analysis Highlights the Role of Temperature Change as a Driver of Alien Foraminifera Invasion
Invasive alien species threaten biodiversity and ecosystem structure and functioning, but incomplete assessments of their origins and temporal trends impair our ability to understand the relative
Unlocking the history of a trans‐Atlantic invader: Did the human slave trade impact Brown mussel dispersal?
Brown mussels exhibit a trans‐Atlantic distribution putatively caused by either native dispersal or artificial gene flow, likely in concert with the transport of enslaved people from Africa.
Population Genetic Structure Is Unrelated to Shell Shape, Thickness and Organic Content in European Populations of the Soft-Shell Clam Mya Arenaria
Shell thickness did not vary significantly with either latitude or genotype, although PR thickness and calcification were positively associated with latitude, while CCL thickness showed a negative association.

The soft‐shell clam Mya arenaria is one of the most ancient invaders of European coasts and is present in many coastal ecosystems, yet little is known about its genetic structure in Europe. We
Historical faunal exchange between the Pontocaspian Basin and North America
It is suggested that a bird‐mediated and/or ocean current‐mediated faunal interchange via the Arctic Ocean occurred during the Late Pliocene or Early Pleistocene, likely facilitated by reduced distances between the Eurasian and North American/Greenland landmasses, marine introgressions, and a stepping‐stone system of brackish‐water habitats in northern Siberia, as well as a lack of competition along the migration route.
