摘要

对沉积物中大型底栖生物垂直分布的研究仍然很少;来自高纬度地区的数据尤其稀少。与此同时,人们认为它包含了有关群落的重要信息,不应被忽视。因此,我们的主要目标是研究北极地区大型底栖生物垂直分布模式的特殊性,并找出该地区特有的特征。为此,我们于 2019 年乘坐 "Akademik Tryoshnikov "号考察船在北巴伦支海和弗朗茨-约瑟夫地西南横断面漂流时对 24 个站点进行了采样。使用箱式取样器采集沉积物;之后,使用管式取样器采集子样本,并切割成垂直子岩心。三至四个层(取决于生物群落)的物种组成和丰度相似。没有发现物种丰富度的增加与垂直结构的复杂化有直接关系。在一些关系密切的物种群中,可以观察到它们通过在一个站点的不同层中栖息来避免竞争。决定底栖生物特性的重要因素取决于不同的层。与低纬度地区相比,上薄层在物种数量和丰度方面发挥着更重要的作用。然而,最丰富和分布最广的多毛类物种 Spiochaetopterus typicus 的深度可达 30 厘米。它在大多数站点的较深沉积层中形成垂直分布模式,包括促进其他物种向深层渗透。但以大型多毛类为主的站点例外。这种垂直分布模式,即物种丰富度和丰度的大部分集中在几厘米的上层,加上少数物种的极深渗透,很可能是欧亚北极陆架的典型特征。

Vertical distribution patterns of macrofauna in the sediments of the Arctic cross-shelf trough and adjacent shelf - Similarities and differences from lower latitudes

Vertical distribution of macrobenthos in sediments remains poorly studied; data from higher latitudes are especially scarce. At the same time, it is believed to contain important information about communities that should not be neglected. Hence, our main objectives are to study the peculiarities of macrobenthos vertical patterns in the Arctic and to find out features specific to this region. For this, 24 stations were sampled in 2019 aboard the R/V “Akademik Tryoshnikov” while drifting in the North Barents Sea and along a transect south-west of the Franz Joseph Land. Sediments were obtained using a box corer; afterwards, subsamples were taken by a tube corer and cut into vertical sub-cores. Three to four strata (depending on biotope) characterized by similar species composition and abundance were distinguished. No direct relation between the increase in species richness and the complication of vertical structure was found. Avoiding competition through dwelling in different layers at one station was observed in some groups of closely related species. Factors playing important roles in determining infaunal properties depended on the layer. The thin upper layer played a more important role in terms of species number and abundance as compared to lower latitudes. However, the most abundant and widespread polychaete species Spiochaetopterus typicus penetrated down to 30 cm. It formed vertical distribution patterns in deeper sediment layers at most stations, including facilitating penetration into deep layers for other species. The exception was stations dominated by large maldanid polychaetes. Such a vertical pattern, with a particularly large share of species richness and abundance concentrated in the several upper cm combined with the very deep penetration of a few species, is likely typical of the Eurasian Arctic shelf.

期刊介绍: Deep-Sea Research Part I: Oceanographic Research Papers is devoted to the publication of the results of original scientific research, including theoretical work of evident oceanographic applicability; and the solution of instrumental or methodological problems with evidence of successful use. The journal is distinguished by its interdisciplinary nature and its breadth, covering the geological, physical, chemical and biological aspects of the ocean and its boundaries with the sea floor and the atmosphere. In addition to regular "Research Papers" and "Instruments and Methods" papers, briefer communications may be published as "Notes". Supplemental matter, such as extensive data tables or graphs and multimedia content, may be published as electronic appendices.
