 note = {P(論文), Surface water samples were collected at 15 sites in the Greenland and Norwegian Seas, and total planktonic thraustochytrids and bacteria were directly counted by epifluorescence microscopy. Particulate (>0.2 μm) adenosine 5'-triphosphate (ATP) was also determined by bioluminescence photometry. Abundance of planktonic thraustochytrids varied from below the detection limit (<8.1×102 l^(-1)) to 2.3×105 l^(-1) with an overall average of 3.1×104 l^(-1). Abundance of bacterioplankton ranged from 2.2×107 l^(-1) at the northernmost site to 6.0×108 l^(-1) at the southernmost site with an overall average of 2.1×108 l^(-1). Particulate ATP concentration ranged from 79 pmol to 676 pmol at the mid-transect (68°N) and southernmost (62°N) sites, respectively, with an overall average of 222 pmol. The measured ATP concentrations were too low to account for the abundance of thraustochytrids and bacteria estimated from total counts and carbon-per-cell factors. However, particulate ATP was correlated with the abundance of bacterioplankton, but not that of planktonic thraustochytrids. These differing relationships suggest different physiological and biochemical strategies of starvation survival and differing substrate availability in the Arctic and sub-Arctic surface waters.},
