P. homomalla and a single Briareum asbestinum colony were preferred in 1986 (Other category in Fig. 3; G = df = 2, P < ). As in the occupancy data, Plexaura Aâthe most abundant gorgonian at Korbiskiâwas visited less fre- quently than expected. This strong avoidance of Plex- aura A colonies was the primary factor creating the sig- nificantly non-random movement patterns at Korbiski (Fig. 3; 1984, G = , df = 3, P < ; 1985, G = , df= 3, P< ; 1986, G = , df = 2, P <£ ). Positive preferences in movement patterns were variable between years. The most preferred species in the 1984, 1985, and 1986 seasons were Eunicea spp., Pseudoplexaura spp., and P. homomalla, respectively. The preference for Eunicea spp. in 1984 was generated by three short visits to Eunicea colonies and is not re- flected in the occupancy data. Movement preferences in 1985 and 1986 varied between years but were consistent with the occupancy data. Differences in residence times on colonies were the dominant factors creating differences in the occupancy patterns at Korbiski. both 1984 and 1985, the gorgo- nian colonies on which dividual snails remained lon- gest were also identified as eferred species by the occu- pancy data (Fig. 3). Residence time on Pseudopterogor- gia and Pseudoplexaura spp. were
