Abstract

The subtropical to subpolar planktic foraminifera Globigerina bulloides is a calcifying marine protist, and one of the dominant foraminiferal species of the Nordic Seas. Previously, the relative abundance and shell geochemistry of fossil G. bulloides have been studied for palaeoceanographic reconstructions. There is however a lack of biological observations on the species and a poor understanding of its ecological tolerances, especially for high latitude genotypes. Here, we present observations from the first extensive culturing of G. bulloides under subpolar conditions, including the first low temperature (6-13°C) and variable salinity (30-38) experiments. Carbonate chemistry (pH and [CO3 2-]) was also manipulated. Experimental conditions were chosen to reflect a range of plausible past and future scenarios for the Nordic Seas. We found G. bulloides to be tolerant of environmental conditions well outside their optimal range (<10°C, salinity <33, pH <8). Observed life span was up to three months, which was attributed to a microalgal diet. Two alternative life strategies were employed, whereby individuals either experienced rapid growth and death, or a prolonged lifespan with minimal growth and death via slow decay. We posit this could help explain differences in geochemical signals recorded from different size fractions of fossil specimens used for palaeoceanographic reconstructions.

对亚极地有孔虫 Globigerina bulloides 的大规模培养揭示了其对与不同生命策略和延长寿命相关的大量环境参数的耐受性。
亚热带至亚极地浮游有孔虫 Globigerina bulloides 是一种钙化海洋原生动物,也是北欧海洋的主要有孔虫物种之一。在此之前,人们曾对有孔虫化石的相对丰度和外壳地球化学进行过研究,以用于古海洋学重建。然而,我们缺乏对该物种的生物学观察,对其生态耐受性也缺乏了解,尤其是对高纬度基因型。在此,我们介绍了首次在亚极地条件下广泛培养 G. bulloides 的观察结果,包括首次低温(6-13°C)和可变盐度(30-38)实验。此外,还对碳酸盐化学(pH 值和 [CO3 2-])进行了操作。实验条件的选择反映了北欧海域过去和未来的各种可能情况。我们发现 G. bulloides 能够耐受其最适范围之外的环境条件 (
