与2014年的海洋热浪和2016年的强烈厄尔尼诺现象相吻合,热带温带远洋殖民被囊动物Pyrosoma atlanticum的爆发扩展到北方加州海流(NCC)。考虑到P.根据在NCC中观察到的atlanticumcolonies及其高放牧率的潜力,我们假设该物种可能对东北太平洋的浮游植物现存量产生重大的负面影响。在2018年冬末、春季和初秋,我们测量了P.大西洋沿岸的俄勒冈州,估计他们的春季放牧对当地浮游植物现存量的影响。P.大西洋在冬末达到高峰(0.7个菌落m−3),在春季下降(0.42个菌落m−3),并在初秋下降到几乎没有(0.07个菌落m−3)。我们观察到P的中值大小增加了一倍。从冬末到春季,大西洋的殖民地,其次是在初秋的大小下降。由于其高的个体群体肠道色素含量和开花密度,整个春季放牧的影响P。大西洋的浮游植物数量很大,最高达到现有浮游植物现存量的22%。
Coinciding with the marine heat wave in 2014 and a strong El Niño in 2016, blooms of the tropical-temperate pelagic colonial tunicate,Pyrosoma atlanticum, expanded into the Northern California Current (NCC). Given the high densities ofP. atlanticumcolonies observed in the NCC, and their potential for high grazing rates, we hypothesized that the species could have a substantial negative effect on the phytoplankton standing stock in the Northeastern Pacific Ocean. In the late winter, spring and early autumn of 2018, we measured abundances and length frequencies ofP. atlanticumcolonies off the coast of Oregon and estimated their spring grazing impact on the local phytoplankton standing stock. Abundances ofP. atlanticumpeaked in late winter (0.7 colonies m−3), dropped off in spring (0.42 colonies m−3), and declined to near-absent in early autumn (0.07 colonies m−3). We observed a doubling in the median size ofP. atlanticumcolonies from late winter to spring, followed by a decline in size in early autumn. With their high individual colony gut pigment contents and bloom densities, the overall spring grazing impact ofP. atlanticumwas substantial, reaching a maximum of 22% of the available phytoplankton standing stock.
