“…Recruitment was consistently more abundant on the underside of panels, as in previous studies of Pomatoceros (Dons, 1943;Klo« ckner, 1976;Moate, 1985). Tube worms and other fouling organisms prefer to settle on downward facing surfaces (Wisely, 1959;Sentz-Braconnot, 1968;Relini & Sara, 1971).…”

Recruitment patterns of serpulids (Annelida: Polychaeta) in Bantry Bay, Ireland

2003

Interannual and seasonal variation in recruitment of serpulid tube worms was monitored at two depths at each of four sites between February 1999 and January 2001 in Bantry Bay, Ireland. In both years, a single peak in recruitment was observed. The timing of the peak was similar in both years, but the magnitude of the peak differed significantly. More individuals recruited onto the underside than on the upperside of the horizontally orientated panels. A higher density of recruits was observed at a depth of 7 m than at 4 m during recruitment maxima. There was little variability in recruitment rates either within or between sites. The proportions of Pomatoceros triqueter and P. lamarckii recruiting per deployment were examined. Juvenile mortality was high. Based on ongrowing laboratory experiments, the dominant species was P. lamarckii. Serpula vermicularis was also present in low abundance. Examination of the spatial patterns of distribution of the serpulids indicated that the recruits were aggregated within panels. The degree of aggregation was correlated with the overall density of recruitment per panel.

“…Sentz-Braconnot (1968) suggests that populations of Pomatoceros triqueter sensu lato become attractive to conspeci¢c larvae above a certain density only. This is corroborated by the experiments of Klo« ckner (1976).…”

“…Many of the publications on marine hard substrate communities deal with only one particular taxonomic group, for example algae (L(ining, 1970) or Polychaeta (K16ckner, 1976;Gillandt, 1979aGillandt, , 1979b. This would make them particularly useful for the detection of short-term disturbances in the marine ecosystem.…”

Sublittoral hard substrate communities off Helgoland

In the Helgoland region eight subhttoral hard substrate communities occur. These communities were stationary in time during the years 1987-1989. The major governing parameters are the available amount of daylight and the degree of exposure to water movement. In the photic zone, three communities are met with, one of which is widespread and appears to be independent of the exposure to water movement. Under exposed conditions, at the lower border of the photic zone, a second community is observed. A third community is estabhshed on erosive muschelkalk substrates. In the aphotic zone also, three communities are found. The distribution of these communities is related to the rate of water movement. One community is divided into three variants, with different preferences regarding the angle of inclination and nature of the substrates. In the artificially constructed harbours, where sedimentation exceeds erosion, two different communities have setfled. In the community under moderately sheltered conditions many species are found which also occur in the natural photic zone. Under extremely sheltered conditions a group of species has become dominant which is very rare in the Helgoland region outgide the quay-walls but which has been described as being characteristic for sheltered localities elsewhere.
