“…This phenomenon might explain some of the variations of recruitment onto settlement panels in the field in previous studies that neglected to examine protozoa in the biofilms. For example, settlement of various invertebrates has been found to differ among natural biofilms of different ages (Keough & Raimondi 1995, Bao et al 2007), grown in different seasons (Wieczorek et al 1996, Bao et al 2007, and grown in different locations (Dobretsov & Qian 2006, Hung et al 2007. In these studies and others, such effects have been attributed to assumed differences in the general microbial film community or specifically to measured differences in bacteria, but the ciliate assemblages might also have played important roles.…”

“…More recently, settlement has been shown to relate to the presence of certain taxa of microorganisms, by either corre lation or experimental demonstration. These taxa include bacteria (Dobretsov & Qian 2006, Bao et al 2007, Hung et al 2007, diatoms (Harder et al 2002a, Lam et al 2003, and thraustochytrids (Raghukumar et al 2000). Some metabolites and extracellular polymers of bacteria and diatoms have been isolated and identified as the cues to which various invertebrate larvae respond (Harder et al 2002b, Lau et al 2003, Lam et al 2005, Patil & Anil 2005, Hung et al 2009).…”

“…G. caespitosa is a gregarious settler that forms dense reef-like mats on intertidal rocks (Minchinton 1997), whereas populations of P. taeniata consist of sparser, prostrate tubes. The blue mussel Mytilus galloprovincialis (previously considered a subspecies of M. edulis, Gosling 1994) is a common aquaculture species, and its larval settlement is stimulated by biofilms (Bao et al 2007). The cosmopolitan, arborescent bryozoan Bugula neritina is also known to respond to biofilm cues (Dobretsov & Qian 2006), but it differs from the other species we tested by having a briefer, nonfeeding larval stage that is considered a relatively indiscriminate settler (Dahms et al 2004).…”

Settlement of benthic marine invertebrate larvae often limits recruitment, influencing the structure and dynamics of natural populations as well as biofouling of marine infrastructure, ship hulls, and aquaculture operations. Certain microbial components of substratum biofilms influence settlement (e.g. bacteria, diatoms), but the importance of biofilm protozoa has been unknown. We tested for effects of ciliates by comparing settlement and survival of common fouling invertebrates among 3 biofilm conditions: no biofilm, a purely bac terial biofilm, and a biofilm of bacteria and ciliates. With an assemblage of 7 ciliates (from Hypotrichia, Haptoria, and Scuticociliatia), the serpulid polychaete Galeolaria caespitosa showed a 44 to 49% average reduction in settlement rate compared to the purely bacterial biofilm, and post-settlement mortality increased 7-fold to 34%. In contrast, settlement and survival of the bryozoan Bugula neritina were unaffected. With a partially different assemblage of 11 ciliates (from Hypotrichia, Sticho trichia, Haptoria, Colpodida, and Scuticociliatia), settle ment of the serpulid Pomatoceros taeniata more than doubled, whereas that of the blue mussel Mytilus galloprovincialis was reduced by 54% compared to the purely bacterial biofilm. The results could not be explained by ciliates changing the total abundance of biofilm bacteria. We hypothesize that mechanisms could include direct interactions between larvae and ciliates (physical interactions, interference from ciliates' feeding currents, or responses to chemicals from ciliates), or indirect effects from ciliates altering the bacterial assemblage or its settlement cues. Such large and species-specific effects of ciliates on larval settlement and postsettlement mortality might impact invertebrate recruitment rates and species assemblages, especially because biofilm ciliates are highly variable over time and space.Aggregation of the tubeworm Galeolaria caespitosa. Larval settlement of these and other invertebrates is influenced by ciliates on the substratum.

“…It is, however, not known whether the biofilm developed on the platform construction in 2003 emitted the relevant cues that induce settlement and metamorphosis of Mytilus-larvae (e.g. Bao et al 2007). For example, the induction of mussel settlement requires further metabolites released by macroorganisms such as filamentous algae (Dobretsov & Wahl 2001).…”

The colonization of the underwater construction of an offshore research platform in the German Bight by Mytilus edulis was investigated. Mussel abundance, biomass and percentage coverage of the construction were determined from summer 2003 to summer 2005 from different water depths using digital underwater images and scrape samples of the hard substrate fauna. Growth was estimated from shell length distributions. In 2003 settlement of M. edulis was low at the platform mainly due to a temporal mismatch between platform construction and occurrence of competent larvae. In summer 2004 mussel abundance increased remarkably in the intertidal and upper subtidal. Abundance and biomass increased up to 30,000 individuals m (2 and approximately 40 kg m (2 in summer 2005. At the end of the investigation period, the upper part of the platform foundation was completely covered by M. edulis. Lower parts remained sparsely colonized. Mussel growth rates were high under offshore conditions because of favourable environmental conditions and reduced biological constraints. Cumulative effects from wind farm entities are estimated. Mussel accumulations will be an important component in the estimation of ecological implications of offshore wind farming at least at the local scale.

“…Embora um crescente número de estudos demonstre que as larvas reconhecem substratos colonizados por biofi lmes de diferente composição, idades e ambientes (sublitoral vs. entremarés), a resposta da larva depende da espécie em estudo. Microfi lmes com maior tempo de colonização (maior idade) podem facilitar o assentamento de alguns poliquetos (Qian 1999) e bivalves (Bao et al 2007) ou inibir o assentamento de alguns cirripédios (Olivier et al 2000, Tremblay et al 2007) e briozoários (Dobretsov & Qian 2006). Alguns estudos recentes mostraram que os compostos extracelulares produzidos por alguns dos organismos que compõem o biofi lme induzem ou inibem o assentamento (Lam et al 2005).…”
