Abstract

Background: Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments and water. Z. marina is typically found in marine systems, but it can also proliferate under brackish conditions. Changes in salinity generally have a strong impact on the biota, especially at the salty divide between salinity 6 and 9. To better understand the impact of the salty divide on the interaction between Z. marina and the surrounding sediment and water microbiota, we investigated the effects of Z. marina meadows on the surrounding microbiota across a salinity range of 6-15 in the Baltic Sea during the summer using 16S and 18S rRNA gene amplicon sequencing.

Results: Salinity was the most important factor for structuring the microbiota within both water and sediment. The presence of Z. marina affected the composition of the bacterial and eukaryotic community and bacterial alpha diversity in the sediment. However, this effect was confined to alpha-mesohaline conditions (salinity 9-15). The impact of Z. marina below salinity 9 on water and sediment microbiota was insignificant.

Conclusions: Increasing salinity was associated with a longer leaf length of Z. marina, causing an increased canopy height, which affects the sediment microbiota through reduced water velocity. Hence, we propose that the canopy effect may be the major predictor explaining Z. marina's interactions with the surrounding microbiota at salinity 9-15. These findings emphasize the importance of the physical effects of Z. marina meadow ecosystem services and have important implications for Z. marina management under brackish conditions in a changing climate.

在半咸淡水条件下,带状藻草甸对沉积物和水中微生物群的影响较小。
背景:海藻(Zostera marina)是一个重要的生态系统工程师,它影响着浅水环境,并可能塑造周围沉积物和水中的微生物群。海藻通常生长在海洋系统中,但也能在咸水条件下大量繁殖。盐度的变化通常会对生物群产生很大影响,尤其是在盐度 6 和 9 之间的盐分分界线上。为了更好地了解盐度分界线对滨海藻与周围沉积物和水体微生物群相互作用的影响,我们利用 16S 和 18S rRNA 基因扩增片段测序技术,研究了夏季波罗的海 6-15 盐度范围内滨海藻草甸对周围微生物群的影响:结果:盐度是影响水和沉积物中微生物群结构的最重要因素。游艇藻的存在影响了沉积物中细菌和真核生物群落的组成以及细菌的α多样性。不过,这种影响仅限于α-微碱性条件(盐度 9-15)。盐度 9 以下的藻类对水和沉积物微生物群的影响不显著:结论:盐度的增加与马利筋属植物叶片长度的增加有关,叶片长度的增加会导致冠层高度的增加,而冠层高度的增加会通过降低水流速度来影响沉积物微生物群。因此,我们认为冠层效应可能是盐度为 9-15 时海藻与周围微生物群相互作用的主要预测因素。这些发现强调了马利筋草甸生态系统服务的物理效应的重要性,并对在气候不断变化的咸水条件下管理马利筋草甸具有重要意义。

期刊介绍: Microorganisms, omnipresent across Earth's diverse environments, play a crucial role in adapting to external changes, influencing Earth's systems and cycles, and contributing significantly to agricultural practices. Through applied microbiology, they offer solutions to various everyday needs. Environmental Microbiome recognizes the universal presence and significance of microorganisms, inviting submissions that explore the diverse facets of environmental and applied microbiological research.
