Coastal evolution due to natural and human-induced causes or factors can be rather variable on quite different temporal and/or spatial scales. Our capability to understand and especially predict this variability on the longer time scales is still limited. This can lead to misinterpretation of coastal change information, which hampers informed decision-making and the subsequent functional design...

Genetic polymorphism at the loci encoding the enzymes phosphoglucose isomerase, leucine aminopeptidase and phosphoglucomutase was investigated in Irish Mytilus populations. Allele frequencies and heterozygote proportions indicated that populations on exposed Atlantic coasts differed from those on sheltered Atlantic coasts, and from Irish Sea mussels. When compared with data on M. edulis collect...

The Skagerrak receives large amounts of freshwater, both in the form of rather low-saline waters from the Baltic Sea and the southern North Sea and in pure form from local rivers. These waters, mixed with the underlying Atlantic Water, participate in a variable, mainly wind-driven, cyclonic surface circulation in the Skagerrak. This paper presents a thorough analysis of hydrographic data to pro...

Since the 1970s, the nassariid gastropod Cyclope neritea has been extending its range north along the French Atlantic coasts from the Iberian Peninsula. This may be due to natural spread because of the recent warming of the northeastern Atlantic. However, human-mediated introductions related to shellfish culture may also be a probable explanation for this sudden range expansion. To examine thes...
