The colonization of macroalgal rafts by the genusIdotea(sub-phylum Crustacea; order Isopoda): an active or passive process?

Abstract: The association of invertebrate communities with macroalgae rafts has received much attention over recent decades, yet significant gaps in our knowledge remain with respect to the colonization process. Using laboratory-based experiments andin situfield trials in Strangford Lough, Northern Ireland, this study investigated whether members of the known rafting genusIdotea(sub-phylum Crustacea; order Isopoda) could effectively colonize rafts after shore… Show more

“…A substantial shift in the epibiotic assemblage from benthic to floating seaweeds was evident for mobile but not for sessile epibionts, indicating that high species turnover in the mobile associates in the assemblage explained the compositional changes of the epibiota from benthic to floating seaweeds. Clarkin et al (2012b) observed a similar shift for mobile epibionts for associated idoteid isopods in the Irish Sea.…”

“…Conspicuous accumulations of Idotea spp. on floating seaweeds are common in the N Atlantic (Table 4) and in other parts of the world's oceans (Hobday, 2000), indicating the high potential of this genus for colonizing floating algal patches (Clarkin et al, 2012b) and for rafting dispersal.…”

“…For example, Gutow et al (2009) identified that large numbers of highly mobile macroinvertebrates such as amphipods and isopods left the brown alga Ascophyllum nodosum immediately after being experimentally detached from the seafloor in Iceland. Clarkin et al (2012) indicated that isopods of the genus Idotea could either passively or actively colonise macroalgal rafts either from the water column or transfer amongst contacted macroalgae rafts. In our study, there were large numbers of the Exosphaeroma and Euidotea isopods and the amphipod A. compressa found associated with macrophytes accumulated in the surf zone.…”
