| Abstract |
Littorina rudis (Maton) is a common species on a wide variety of rocky shores. At Newhaven L. rudis is generally abundant on boulders, juveniles being reliant upon empty barnacle shells for shelter. The experimental addition of crevices resulted in greatly increased population densities, suggesting that crevice availability is normally a limiting factor on this shore. A relationship is demonstrated between the size of artificially provided crevices and the mean shell lengths of the populations of L. rudis they support. The relevance of crevice availability and quality, including empty barnacle shells, to the abundance and size distribution of L. rudis and other littorines is discussed. |
