Abstract | Three bacterial isolates (Micrococcus sp., Rhodovulum sp., and Vibrio sp.) from natural biofilms were investigated for their effects on cyprid settlement of Balanus amphitrite in laboratory bioassays. The inhibitive effect of these bacteria was clearly demonstrated by using a choice assay, in which cyprids settled preferentially on surfaces without bacterial pretreatment over those possessing a monospecies bacterial film. This result suggested that the inhibitive effect was mediated by direct larval contact with bacterial film surface rather than the perception of diffusible bacterial products. In a no-choice assay, monospecies bacterial films of different cell densities reduced cyprid settlement in a density-dependent manner. Vibrio sp. was the most potent inhibitor among the three isolates as it effectively inhibited cyprid settlement by relatively low-density films. The cells of Vibrio sp. were the smallest among the three isolates, suggesting that the correlation between bacterial cell density and cyprid settlement might not be merely due to the reduction of free-space availability. For all three isolates, films that were killed by formaldehyde or UV treatment were as potent as untreated, live films. These films remained inhibitive even in the presence of a strong promoter for cyprid settlement, namely conspecific settlement factor (SF), obtained from adult B. amphitrite. However, SF reverted the inhibitive effect of natural biofilms developed in the intertidal region. © 2003 Elsevier Science B.V. All rights reserved. |
