“…hard bottom surfaces. There is though, some debate about whether artificial substrates are truly representative of natural substrates in terms of colonization by natural communities (Atilla et al 2003, Danovaro & Fraschetti 2002, Smith & Rule 2002. For example, Smith & Rule (2002) found that assemblages in scourers with direct contact to the substratum were more similar to natural assemblages than those in scourers suspended in the water-column while Danovaro & Fraschetti (2002) found that they were radically different.…”

As part of a larger comparative study, marine polychaete hard-bottom assemblages were surveyed using artificial substrate units (ASUs) deployed at four sites off the islands of Trinidad and Tobago. The polychaete fauna was represented by 19 families comprising 89 species. The syllid Exogone dispar was the most abundant polychaete followed closely by the serpulid Pseudovermilia occidentalis. At the family level, the polychaete fauna inhabiting the ASUs is similar to the fauna from other temperate and tropical locations. Omnivorous species were dominant (70 %), followed by filter feeders (20%). This survey provides first records of the hard-bottom polychaete fauna of Trinidad and Tobago and adds new information about the geographic range of some polychaete species. Rev. Biol. Trop. 58 (1): 147-157. Epub 2010 March 01.

“…Meiofauna communities on hard substrata tend to differ radically from those in neighbouring sediments (Atilla and Fleeger 2000;Danovaro and Fraschetti 2002;Atilla et al 2003), but the dynamics of colonization and succession of these organisms and their role, if any, in fouling processes, remain unknown. Nematodes are usually by far the dominant meiofauna in soft sediments (Heip et al 1985), and are known to occur in a wide range of-sometimes extreme-habitats including microbial biofilms on hard substrata (Atilla et al 2003). Like other meiofauna they have, however, very limited active dispersal capacities.…”

Colonization and early succession on artificial hard substrata by meiofauna

An experiment was undertaken at Farol Island, Brazil, to examine colonization of bare aluminium surfaces by microbes and meiofauna. It was hypothesized that a primary source of meiofaunal colonists was sediment resuspended during upwelling events, two of which occurred during the experiment. Microbial biofilms formed on the experimental substrata within 1 day, and continued to develop throughout the experimental period. Among meiofaunal groups copepods also appeared on the first day, and nematodes on the second. Meiofaunal community structure developed in three main phases: an initial phase of 2 days, characterized by low abundances of copepods; a second phase during the first upwelling period characterized by higher abundances of copepods and also by turbellarians; and a third phase from day 13 onwards characterized by relatively stable abundances of a range of taxa including copepods, cirripedes, nematodes and ostracods. Nematode assemblages also developed in three phases, but with different timings coinciding with upwelling events: an initial phase, from the beginning of the experiment to day 9, characterized by few species and low (or no) abundances; a second phase following the first upwelling characterized by moderate abundances of Chromadorina, Chromadorella, Daptonema and Euchromadora sp. 3; a third phase following the second upwelling period (from day 26 onwards) in which Daptonema disappeared and the assemblage was characterized by moderate to high abundances of Euchromadora (species 1 and 2) and Chromadorella. Although shifts in nematode assemblage structure coincided with upwelling events no evidence was found for sediments being the primary source of colonizers on the aluminium substrata, in contrast to our hypothesis.
