Abstract

A semi- quantitative time series (2013-2017) was used to present the recent events of scyphomedusae appearance and abundance in the Boka Kotorska Bay, Montenegro, Southeast Adriatic. Six meroplanktonic species were recorded: Aurelia spp, Chrysaora hysoscella, Cotylorhiza tuberculata ̧ Discomedusa lobata, Drymonema dalmatinum and Rhizostoma pulmo. Among them, C. hysoscella and D. lobata dominated in the water column during winter and spring, forming dense aggregations in March and May, and February to May, respectively. Our description of the D. lobata blooms are actually the first known records of blooms for this species. C. tuberculata was observed in the Bay principally in August and September. The bloom was occurred only in 2017, being the first information of C. tuberculata mass appearance in this area. We hypothesized that global warming phenomena could trigger the observed changes, and in this respect, long-term trends of sea surface temperature (SST) fluctuations were analysed. The scyphomedusae blooms coincided with high positive SST anomalies, noted in the last seven years for this area. To better understand the mechanisms underlying changes in their phenology and abundance, detailed studies on benthic stages in the Bay are essential.

黑山博卡-科托尔斯卡湾（亚得里亚海东南部）的镰刀水母动物群的最新变化（2013-2017）

本文采用半定量时间序列(2013-2017年)分析了亚得里亚海东南部黑山博卡科托斯卡湾水龙类的出现和丰度。共记录到6种浮游生物，分别为:小叶虫、小叶虫、结核子叶虫、白斑虫、斑点虫和肺根口虫。其中，冬春两季水柱以水蚤为主，3 - 5月和2 - 5月形成密集聚集;我们对D. lobata花的描述实际上是该物种的第一个已知的花记录。结核分枝杆菌主要在8月和9月出现。该花期仅在2017年发生，是该地区结核杆菌团块出现的第一个信息。我们假设全球变暖现象可能触发观测到的变化，并就此分析了海表温度波动的长期趋势。在过去七年中，该地区的水花与海温高正异常相吻合。为了更好地了解其物候和丰度变化的机制，对海湾底栖生物阶段的详细研究是必不可少的。
