Temperature-salinity-abundance diagram for A. ohtsukai and A. pacifica.
Aundance (ind./m3) of each species is estimated by multiplying numbers on scale by 100 for A. ohtsukai (black circle) and A. pacifica (white circle).
Nota: Zooplankton samples were collected from 40 stations withn Gwangyang (southern Korea), towed vertically from the bottom to the surface layer during November 2005, and February, May and August, 2006. Specimens identified as O. ohtsukai and A. pacifica were sorted from the samples. Patterns of their occrrence were plotted on a Temperature-Salinity diagram.
The habitats of specimens as A. ohtsukai and A. pacifica in Gwangyang Bay were pronouncedly segregated.
A. ohtsukai was found in Gwangyang Bay and in adjacent coastal zone after the rainy season in late June to July when a large volume of freshwater flows into Gwangyang Bay from the Seomjin River. This inflow decreases salinity to less than 30.0 psu. In contrast, its sibling species A. pacifica occurred offshore in more than 32.0 psu. As the salinity of the regions again increased above 32.0 psu after the rainy season, A. ohtsukai was replaced by A. pacifica; at this time A. ohtsukai was restricted in its distribution to the Seomjin River estuary. Both species were absent from those areas where the water temperature was lower than 12°C. |
