“…The invasive barnacle E. modestus reproduces continuously throughout the spring and summer months of the year, redeveloping as soon as each brood matures (Crisp and Chipperfield 1948, Crisp and Davies 1955, O'Riordan and Murphy 2000. A phenological response does not have very dramatic consequences for species that reproduce continuously.…”

Abstract. Studies of the impacts of climate and climate change on biological systems often attempt to correlate ecological responses with basin-scale indices such as the North Atlantic Oscillation (NAO). However, such correlations, while useful for detecting long-term trends, are unable to provide a mechanism linking the physical environment and ecological processes. Here we evaluate the effects of the NAO on recruitment variability of rocky intertidal invertebrates in the North Atlantic examining two possible climate-related pathways. Using a highly conservative test we interpret associations with the NAO integrated over a season (three months) as an indicator of atmospheric effects on newly settled recruits (NAO3), and the effects of the NAO integrated over six months (NAO6) as an indicator of changes in ocean circulation affecting patterns of larval transport. Through an extensive literature survey we found 13 time series, restricted to southwest Ireland and Britain and comprising five species, that could be used for statistical analysis. Significant correlations with NAO3, our proxy for atmospheric effects, were observed in the south-central domain of our study region (southwest Ireland and south England). Significant correlations with NAO6, the proxy for ocean circulation effects, were detected on southwest Ireland. The associations were detected for three (two barnacles and a topshell) at two sites. These results suggest that the NAO can have effects on the recruitment of intertidal invertebrates through different pathways linked to climate and be distributed heterogeneously in space. Based on previous evidence and the sign and geographic location of significant correlations, we suggest that winter NAO effects are likely to occur as a result of effects on the survival of early life stages settling during spring or through changes in phenology. Our results argue that a combination of modeling and synthesis can be used to generate hypotheses regarding the effects of climate on recruitment and aid in the design of field-based tests of explicit ecological mechanisms.

“…In 1945 it was noticed on the south-east coast of England. 171 It must have arrived at least a few years before this, as a survey in 1947 showed that it was widespread from Norfolk to Dorset, and it was also living in one spot in South Wales. This barnacle is certainly able to get about on the hulls of ships, for it fouls them quite intensely, and was taken early on from a vessel going between Holland and England.…”

“…Our investigations on the distribution of barnacles (Crisp & Chipperfield, 1948;Crisp, 1950;Southward, 1950Southward, , 1951Norris & Crisp, 1953;Southward & Crisp, 1952, 1954aBishop & Crisp, 1957, 1958 were prompted by the lack of quantitative information on the distribution of most species. During these investigations we noted that the distribution of barnacles and of other species of shore animals had certain features in common.…”

The English Channel may conveniently be divided into a western basin and an eastern basin separated by a line drawn approximately between the Cherbourg peninsula and the Isle of Wight. In these basins, the environmental factors are very different. Thus the water of the western basin is on average warmer and slightly more saline than that of the eastern basin and its temperature variation is less extreme. The French side of the Channel is warmer than the English coast only in the western basin. The tidal oscillations in the two basins are out of phase with each other and the strongest tidal currents occur where the two basins join. The main residual flow is up-Channel with minor coastal eddies.The shores at the western end of the Channel are generally rocky, they are close to deep water, and so are exposed to frequent heavy swells. The shores of the eastern basin are generally erodible, and accumulations of sand and shingle tend to reduce the force of the waves. The water of the eastern basin generally contains more suspended matter and the shores are usually scoured by sand and shingle.The distribution of the following animals is given in some detail and compared with earlier records: Ammonia sulcata, Actinia equina, Chthamalus stellatus, Balanus balanoides, B. perforatus, B. crenatus, B. improvisus, Elminius modestus, Verruca stroemia, Hemioniscus balani, Patella vulgata, P. depressa, P. aspera, Monodonta lineata, Gibbula umbilicalis, G. pennanti, G. cineraria, Littorina saxatilis, L. littoralis, L. littorea, L. neritoides, Paracentrotus lividus. The distribution of certain other species is also discussed: Balanus balanus, Haliotis tuberculata, Gibbula magus and Calliostoma zizyphinum.
