Abstract

The results of floristic studies on plankton in the Barents Sea performed from 2007 to 2018 are discussed in the paper. The findings of 16 species new to the indigenous flora were documented and their distribution in the Barents Sea and adjacent waters was analyzed. We also calculated statistical indicators (indices) that characterize the regularity and quantitative expression of their presence in certain sectors of the sea. The data obtained demonstrate the intensity and direction of invasion of Atlantic algal flora. The most intense and regular invasion is directed eastward from the southwestern border of the Barents Sea to its central part. No less stable, but a less intense vector of influence of Atlantic flora was found in the northwestern Barents Sea directed southward to the central and eastern parts of the sea. These processes are characterized from the historical aspect as the activation of florogenesis coincident in time and, most likely, caused by the current climatic situation in the region, mainly by the increased advection of Atlantic water. At least one adventive species has been discovered to be currently integrated into the succession system of the Barents Sea phytoplankton in the position of seasonal dominant.

巴伦支海植物区系发现：气候趋势是植物发生的因素

摘要

本文讨论了2007年至2018年在巴伦支海进行的浮游生物区系研究的结果。记录了对土著植物区系的16种新物种的发现，并分析了它们在巴伦支海和邻近水域的分布。我们还计算了统计指标（指数），这些指标表征了它们在某些海洋区域中存在的规律性和定量表达。获得的数据证明了大西洋藻类植物入侵的强度和方向。最强烈，最规律的入侵是从巴伦支海的西南边界向中部向东。在西北巴伦支海中，向南指向海中部和东部的部分地区，也发现了同样稳定的大西洋植物群，但强度却减弱了。从历史的角度来看，这些过程的特征在于植物发生的激活在时间上是同时发生的，并且很可能是由该地区当前的气候状况引起的，主要是由于大西洋对流的增加。目前发现至少一种外来物种已在季节性优势种群中纳入了巴伦支海浮游植物的演替系统。
