Abstract
    The recruitment and mortality of two common ctenostome bryozoa within a Fucus serratus community in the Menai Strait, north Wales are described. Larvae of Alcyonidium hirsutum settled between August and February; maximum recruitment of these bryozoans occurred during early November and July. Colonisation intensity varied between sites and between years. We suggest that at settlement the larvae of Alcyonidium may be capable of detecting the presence of conspecifics and potential competitors already present on the plant fronds. Habitat selection by A. hirsutum and F. hispida and the relationship between the life cycles of these two spatially dominant bryozoans and that of their main host species, F. serratus are briefly discussed.
