摘要

本研究报道了在斯洛文尼亚海岸(亚得里亚海北部的里雅斯特湾)发现的一种以前未知的非本地红藻。介绍了该物种的分布、丰度、形态特征和繁殖物候。该研究基于从2021年冬季到秋季为期一年的季节性采样,在中沿海地区的两种不同基质(石灰石和砂岩)上进行,结果显示,在冬春和夏秋期间,冈村c种群的生物量存在适度变化。受冈村梭菌影响的两种基质的原生藻类群落物种多样性普遍有限,主要以体型小、形态简单的藻类为主。在研究过程中,除了发现了冈村梭菌的非育性菌体外,还发现了带四孢子囊的四孢子体和带包囊的雌性配子体。

Morphological and reproductive phenology of the non-native red alga Caulacanthus okamurae Yamada (Gigartinales, Caulacanthaceae) from the Slovenian coast (Gulf of Trieste, northern Adriatic)
This study reports the occurrence of the non-native red alga Caulacanthus okamurae, previously unknown on the Slovenian coast (Gulf of Trieste, northern Adriatic Sea). The distribution of the species, its abundance, morphological characteristics and reproductive phenology are described. The study is based on seasonal sampling conducted during one year, from winter to autumn 2021, on two different substrates (limestone and sandstone) of the midlittoral zone, and showed a moderate variation in the biomass of C. okamurae populations between the winter-spring and summer-autumn periods. The native algal assemblages of the two substrates impacted by C. okamurae were characterized by generally limited species diversity and consisted mainly of small-sized species with simple morphology. During the study, in addition to non-fertile thalli of C. okamurae, tetrasporophytic thalli with tetrasporocysts and female gametophytes with cystocarps were found.
