“…Fragments of various parts of the barnacles' bodies (Knight-Jones 1953), removed barnacle bases (Knight-Jones 1953, Crisp 1961, cf. Wethey 1984 and extracts from conspecifics (Crisp & Meadows 1962, Larman & Gabbot 1975, Dinnen & Hines 1994, congenerics (Knight-Jones 1955, Dinnen & Hines 1994) and other marine organisms (Larman & Gabbot 1975) have been shown to enhance settlement. Crisp (1961) found that Sembibalanus balanoides settlement leads to a behavioural pattern akin to territoriality in non-sessile organisms, in that settlement leads to a zone of spatial separation beyond the extremities of the cyprid's body.…”

ABSTRACT. Settlement pattern and density of Semibalanus balanoides (L.) in the Clyde estuary were studied on wood, concrete, steel and sandstone rock during 1994. The position of each newly metamorphosed juvenile barnacle was mapped to the nearest 1 mm over the course of 75 tides. The total number of settled barnacles on the surfaces varied between 0 and 24.09 cm-2 The tide number at which 50 % of the total number of barnacles had settled on each surface varied between tide 23 and tide 44. A new measure describing surface roughness in relatlon to S. balanoides settlement using data on cyprid morphology and behaviour was devised; this index was termed Potential Settling Sites (PSS). The number of PSS for 2-dimensional proflles of each of the surfaces, using accurate replicas and a magnified photo mosaic, was measured. For the surfaces the total number of settlers was best related to the index PSSmi, [Settler Density = (5.68 X PS,,,) -4.16; p 0.011. Two other measures of surface roughness, IS0 number, a standard engineering measure of surface relief, and fractal dimensions. were not related to settler density. Settlement pattern was found to vary with settlement density and spatial scale of analysis. A multi-scale analysis using Monsita's index suggested that S, balanoides were generally settllng aggregatedly at low densities (<8 cm-2), wlth strongest aggregatlons at approximately 30 mm block sizes; it is proposed that this was related to the scale of the close exploration behaviour of the cypnd. Settlement at higher densities (>8 cm-2) tended to be random Aggregated settlement at low densities could be related to the requirement to find a mate in close proximity, whereas avoidance of aggregated settlement by S. balanoides at higher densities could potentially be an intraspecific competition avoidance technique. Nearest neighbour analysis at low settlement densities (0.5 to 1.75 cm-2) found that cyprids settled aggregatedly to at least the first nearest neighbour; it is proposed that this is related to small-scale gregarious settlement behaviour.

“…On the substratum, surface contour and microheterogeneity, rock type, organic films and resident flora may influence settlement (Crisp & Barnes 1954, Barnes 1955, Crisp 1961, 1974, Crisp & Meadows 1963, Strathmann & Branscomb 1979, Hudon & Bourget 1981, Strathmann et al 1981, Hudon et al 1983, Wethey 1986, Chabot & Bourget 1988, Le Tourneux & Bourget 1988, Maki et al 1988, Rairnondi 1988a. Conspecifics (and their chemical attractants) promote a gregarious settlement response of cyprid larvae (Knight-Jones 1953, Knight-Jones & Crisp 1953, Crisp 1955, Crisp & Meadows 1962, Luckens 1970, Larman & Gabbott 1975, Wethey 1984, Chabot & Bourget 1988, Raimondi 1988b. The resident macrobenthic community may directly prevent settlement via obstruction by algae (e.g.…”

Variation in settlement and recruitment of the barnacle Semibalanus balanoides (L.) was experimentally investigated in the high, mid and low intertidal zones at 2 adjacent sites (A and B) on a rocky shore in Nova Scotia, Canada, following a rare occurrence of ice-scouring. Manipulations in 100 cm2 quadrats at each intertidal height involved removal of various components of the sessile macrofauna and macroflora, removal of the total community and a control treatment. The availability of free space on the substratum in each quadrat was measured prior to the onset of settlement to determine whether differences in the density of barnacles among treatments were due to differences in the availability of free space or to manipulation. Where the density of settlers was high, it was positively related to the availabhty of free space suggesting that settlement was a simple function of the availability of free space. However, the pattern of settlement varied from the onset to the end of settlement: quadrats from which only barnacles had been removed were occupied early in the settlement period and later-arriving larvae were restricted to less favourable sites where free space was available. Thus, settlement preferences may be masked when the supply of larvae is saturating or the duration of the selction experiment is too long. Where the density of settlers was low and free space was non-limiting, there was no relationship between the density of settlers and the availability of free space. In the high intertidal zone at Site A, the density of settlers was greater in treatments with ephemeral algae (wetter quadrats) than in those without (drier quadrats) In general, early post-settlement mortality in treatments where algae had been removed increased with intertidal height, whereas in treatments where algae were present it remained relatively constant among heights. Post-recruitment mortality did not differ significantly among treatments in the high intertidal zone, suggesting that factors which influence selection of the substratum by cyprid larvae and promote early post-settlement survival may be particularly important in determining subsequent population structure of barnacles in this zone. Post-recruitment mortality, mainly due to predation by whelks, was highest in the low intertidal zone at both sites and did not differ significantly between treatments. In the mid intertidal zone at Site B, whelk foraging appeared to be constrained by desiccation stress and post-recruitment mortality was highest in treatments with Fucus spp. Where predation is intense, initial selection of the substratum by cyprid larvae may have little effect on the subsequent population structure of barnacles.
