The red macroalga is an introduced species in the Mexican Pacific. To date, there are no published studies on its sessile epibionts, including the hydrozoans and bryozoans, which are the dominant epibionts on macrophytes and of significant biological and economic interest.
This study provides insight into the faunal diversity of hydroids growing on . A total of 185 thalli from both herbarium specimens and field samples collected from five sites in La Paz Bay were revised. Each thallus size and the presence of hydroid epibionts in each thallus region were registered. Eight different hydrozoan taxa were growing on the red macroalgae, including the first recorded observation of in the Gulf of California. The sizes of the collected thalli were mostly under 7.0 cm, the maximum number of taxa per thallus was three and the thallus region containing the highest number of epibionts was in the middle. Significant differences were observed amongst the lengths of thalli with and without epibionts. The thalli with epibionts were larger than the thalli without epibionts. Similarly, significant differences were observed amongst the months. The pair-wise test revealed that each month exhibited distinctive epibiont taxa when compared to the others. This study highlights the lack of information on these associations. Further research is needed to understand whether introduced macroalgae can bring non-native epibiont species to an area.
这种红色大型海藻是墨西哥太平洋地区的外来物种。迄今为止，尚未有关于其固着附生生物的已发表研究，其中包括水螅虫纲动物和苔藓虫纲动物，它们是大型植物上的主要附生生物，具有重要的生物学和经济价值。
本研究深入了解了生长在[该红色大型海藻名称未给出]上的水螅虫纲动物的动物多样性。对来自拉巴斯湾五个地点的标本馆标本和野外样本中的总共185个藻体进行了检查。记录了每个藻体的大小以及每个藻体区域中水螅虫纲附生生物的存在情况。八种不同的水螅虫纲分类群生长在这种红色大型海藻上，其中包括在加利福尼亚湾首次记录到的[具体物种名称未给出]。所采集藻体的大小大多在7.0厘米以下，每个藻体上分类群的最大数量为三个，附生生物数量最多的藻体区域在中间。在有附生生物和没有附生生物的藻体长度之间观察到显著差异。有附生生物的藻体比没有附生生物的藻体更大。同样，在不同月份之间也观察到显著差异。成对检验表明，与其他月份相比，每个月都呈现出独特的附生生物分类群。本研究突出了关于这些关联的信息匮乏。需要进一步研究以了解引入的大型海藻是否会将非本地附生生物物种带入一个地区。
