Evolutionary ecology of driftwood talitrids: a review
Marine driftwood, both when floating at the sea surface and after stranding in the supralittoral of a beach, has been inadequately sampled for talitrids throughout the world. It is probable that many more talitrids than the seven currently recognized as driftwood species are extant. Because they are...
