The human-mediated introduction of marine non-indigenous species is a centuries-if not
millennia-old phenomenon, but was only recently acknowledged as a potent driver of …

The extent to which the geographic distributions of marine organisms have been reshaped
by human activities remains underappreciated, and so does, consequently, the impact of …

Parallel evolution of similar phenotypes provides strong evidence for the operation of natural
selection. Where these phenotypes contribute to reproductive isolation, they further support …

We present a detailed review of 269 published studies using Littorina species in the field of
evolutionary ecology during the last 18 years. We first identify the reasons for the special …

Even after decades of investigation using multiple sources of evidence, the natural histories
of some species remain unclear (ie cryptogenic). A key example is Littorina littorea, the most …

Anciently introduced species can be confounded with native species because introduction
pre‐dates the first species inventories or because of the loss of the collective memory of the …

The old ocean is gone. Life in today's seas is changing in an alarming rate. While many
species are dwindling due to overfishing and habitat destruction (Roberts 2007), others …

Intertidal and subtidal communities of the western and eastern coasts of the North Atlantic
Ocean were greatly affected by Pleistocene glaciations, with some taxa persisting on both …

Increasing interest in oceanography and marine biology and its relevance to global
environmental issues continues to create a demand for authoritative reviews summarizing …

The colonial ascidian Botryllus schlosseri should be considered cryptogenic (ie, not
definitively classified as either native or introduced) in the Northwest Atlantic. Although all …
