Abstract

The data of 3-year observations of the abundance dynamics of microplanktonic fraction of Pseudodiaptomus marinus—a new alien copepod for the Black Sea—are presented. Seasonally, the first juvenile stages of the species appeared in the Sevastopol coastal waters in September. The maximum values were reached at different times: from the end of September to the end of November. Then the abundance quickly dropped. The presence of nauplius and copepodites in plankton suggests that the new species of copepods successfully reproduces in the Black Sea coastal waters. The total abundance of the invasive species is characterized by low values, which do not exceed at maximum 10 000 ind. m^–3. The temperature is assumed to be one of the main factors in the regulation of interannual variability in the abundance of the invasive species.

假假单胞菌（Pseudodiaptomus marinus Sato），1913年—黑海入侵的pe足类的新物种：入侵的第一个结果

摘要

提出了为期三年的观测资料，该资料是针对黑海的一种新的外来co足类假单胞假单胞菌微浮游生物级分的丰度动态的。按季节，该物种的第一个少年阶段出现在9月的塞瓦斯托波尔沿海水域。在不同的时间达到最大值：从9月底到11月底。然后丰度迅速下降。浮游生物中存在无节幼体和co足类动物，这表明pe足类动物的新物种在黑海沿岸水域成功繁殖。入侵物种的总丰度以低值为特征，最高不超过10,000 ind。m ^–3。假定温度是调节入侵物种丰富度年际变化的主要因素之一。
