説明
Three species of epiphytic dinoflagellates - Ostreopsis siamensis, O. lenticularis, and O. ovata have recently been found on both the east and west coasts of the upper North Island, New Zealand. The morphological differences of all three Ostreopsis spp. have been studied with both light and scanning electron microscopes. Detailed studies of the inner face of the thecal wall of Ostreopsis siamensis revealed two types of trichocyst pores: small, simple pores and large multipore structures. The multipore structures apparently have not been previously reported. Surveys conducted during the period from November 1995 to April 1997 showed that all three Ostreopsis spp. were fairly widespread in northern New Zealand, and all three species were found to occur south of 35°S latitude. Cell concentrations of Ostreopsis spp. in summer were substantially higher than in early spring. There was also a clear regional difference in distribution; cell concentrations of the dominant species, O. siamensis, were greatest in Rarawa and Tokerau on the north-east coast. Other less abundant epiphytic species recorded during the same period included Prorocentrum lima, P. compressum, and Coolia monotis. These species were generally more sporadic in distribution than Ostreopsis spp.

収集方法
All epiphytic dinoflagellate samples were collected both from seaweeds and surface waters at uninhabited sites. All seaweeds were hand collected from below low water at depths of c. 1 m. There were no coral reefs at these sites. In April 1997 surface seawater samples were collected from Rarawa and Tokerau.
| Study Extent | The study areas were located at the far north of New Zealand stretching from 34°30'S to 35°40'S latitude, and were made up of close inshore embayments on the east coast and open sandy beach on the west coast of the upper North Island. Nearshore waters on the north-east coast are bounded at the shelf edge by the East Auckland Current, a warm high salinity subtropical current (Sharpies 1997; Chang et al. 1998). Typically in summer, warm surface subtropical waters intrude into nearshore waters (Sharpies 1997). On the north-east coast, several sites in the vicinity of Rangaunu Harbour are important commercial shellfish harvesting areas. During the period from November 1995 to April 1997, seaweed samples were collected from the core areas, Rangiputa, Tokerau, Rarawa on the north-east coast, and one site from Reef Pt on the north-west coast of the upper North Island. In March and September/October 1996 additional samples were collected from Cable Bay, Paihia, Urquhart, Whangarei Wharf, and Ocean Beach on the north-east coast, and Scott Pt and The Bluff on the north-west coast of the North Island. |

Method step description:
- A seaweeds and sea water collected were immediately fixed in a final concentration of 5% formaldehyde in a 500 ml plastic jar. Four batches (twice per year) of seaweed samples were collected between November 1995 and April 1997.
- Seaweed samples were processed in the laboratory by shaking vigorously in a jar for a couple of minutes, and rinsing them 3 times with freshly prepared 5% formaldehyde in sea water (c. 200 ml in each rinse). The epiphytic dinoflagellates washed off the seaweeds in all rinses were pooled together, and then sieved through 100 um nylon mesh to remove extraneous matter and left to settle overnight. The supernatant was withdrawn using a suction pump at low pressure the following day and samples reduced to a final volume of 100-200 ml.
