| Abstract: |
| Abundance and spatial distribution of tintinnid ciliates in Jiaozhou Bay, Qingdao. north China, were studied in several cruises in the year 2001 through 2003. Tintinnids were collected by vertical towing using shallow sea type III plankton net (open area 0.1 m2. mesh size 76 μm) onboard of R/V Kejiao II in February, May and August 2001. May. August. November 2002 and February 2003, separately. Tintinnid species were identified according to Yin (1952). Nie et al (1947). Wang et al (1932) and You et al (1988).
Temperature varied significantly in four seasons in the area: 3.87 - 4.72°C in February, 14.59 - 18.74°C in May. 25.11 - 26.39°C in August, and 10.31 - 15.58°C in November. Different species of tintinnids dominated in different seasons. The dominant species occurred in these cruises were: in February 2001: Tintinnopsis brasiliensis (1500 - 23900 ind/m3); in May 2001: Codonellopsis mobilis (80600 - 624000 ind/m3, Leprotintinnus neriticus (920 - 13842 ind/m3), Favella campanula (184 - 2728 ind/m3), T. kofoidi (0 - 368 ind/m3); in August 2001: Stenosemella sp. (0 - 982 ind/m3), T. radix (98 - 19114 ind/m3), L. neriticus (0 - 5932 ind/m3), F. panamensis (0 - 1318 ind/m3). T. gracilis (0 - 317 ind/m3), L. nordqvisti (0 - 158 ind/m3); in May 2002: C. mobilis (22400 - 1567500 ind/m3), L. neriticus (900 - 96300 ind/m3), C. parvicollis (0 - 75600 ind/m3); in August 2002: F. panamensis (0 - 2604 ind/m3), C. mobilis (0 - 992 ind/m3), T. gracilis (0 - 256 ind/m3), L. nordqvisti (0 - 102 ind/m3), and in November 2002: C. ostenfeldi (0 - 13003 ind/m3), L. neriticus (0 - 713 ind/m3), T. schotti (0 - 316 ind/m3). The abundance of tintinnids was below 50 ind/m3 in February 2003.
Tintinnid assemblies in Mays of both 2001 and 2002 were featured by high abundance (maximum 1740000 ind/m3), and the dominant species were C. mobilis and L. neriticus. The largest number of species appeared in Augusts of both 2001 and 2003 with dominating T. radix, F. panamensis, T. gracilis, L. nordqvisti. Five species (C. ostenfeldi, T. schotti, T. kofoidi, L. neriticus, Stenosemella sp.) were found to be new records in this area. Ecological data indicated that different spatial distribution patterns might be related to water exchange inside and outside of the bay. Chlorophyll a concentration was not the key factor influencing the occurrence of tintinnids. |
