海洋原生生物在中层和深层的放牧,以及它们随后对真核生物和原核生物之间的营养联系的影响,没有得到很好的限制。最近的研究表明,原生生物的摄食活动比预期的要高,一直到中层深海。这项研究提供了第一次探索原生动物放牧在深海北大西洋深水(NADW)。放牧测量整个水柱在南大西洋的三个站使用荧光标记的猎物类似物。在南极中层深水(AAIW)和NADW中的放牧使三个站位的现存原核生物量减少了3.79% ± 1.72%~ 31.14% ± 8.24%。这些结果意味着,原生动物放牧可能是一个重要的来源,不稳定的有机碳在一定的中层和深海深度。
Oceanic protist grazing at mesopelagic and bathypelagic depths, and their subsequent effects on trophic links between eukaryotes and prokaryotes, are not well constrained. Recent studies show evidence of higher than expected grazing activity by protists down to mesopelagic depths. This study provides the first exploration of protist grazing in the bathypelagic North Atlantic Deep Water (NADW). Grazing was measured throughout the water column at three stations in the South Atlantic using fluorescently-labeled prey analogues. Grazing in the deep Antarctic Intermediate water (AAIW) and NADW at all three stations removed 3.79% ± 1.72% to 31.14% ± 8.24% of the standing prokaryote stock. These results imply that protist grazing may be a significant source of labile organic carbon at certain meso- and bathypelagic depths.
