“…Although nematodes have been collected from plankton samples (Hagerman & Rieger, 1981;Sibert, 1981) and marine snow (Shanks & Walters, 1997), they are poor swimmers (Fegley, 1985) and likely become suspended in the water column via external forces (water currents or bioturbation), as is assumed for most meiofaunal taxa (Hagerman & Rieger, 1981;Mott & Harrison, 1983;Fleeger et al, 1984;Fegley, 1985;Armonies, 1988;Palmer, 1988;Bertelsen, 1998;Powers, 1998;Fonseca-Genevois et al, 2006). Many harpacticoid copepods, however, are much better active dispersers than nematodes (Widbom, 1983;Ó lafsson & Moore, 1990Ó lafsson & Moore, , 1992 and occasionally enter the water column under their own power (Alldredge & King, 1980, 1985Bell et al, 1988;Kurdziel & Bell, 1992;Walters and Bell, 1994;Teasdale et al, 2004).…”
