Theoretical ecological models, such as succession and facilitation, were defined in terrestrial habitats, and subsequently applied to marine and freshwater habitats in intertidal and then subtidal realms. One such model is the soil seed bank, defined as all viable seeds (or fruits) found near the soil surface that facilitate community restoration/recovery. “Banks of microscopic forms” have been hypothesized in aquatic habitats and recent work from aquaculture has highlighted dormancy in algal life cycle stages. To reinvigorate the discussions about these algal banks, we discuss differences in life cycles, dispersal, and summarize research on banks of macroalgal stages in aquatic ecosystems that may be easier to explore with modern advances in molecular technology. With focus on seminal work in global kelp forest ecosystems, we present a pilot study in northern California as proof of concept that Nereocystis luetkeana and Alaria marginata stages can be detected within kelp forests in the biofilm of rocks and bedrock using targeted primers long after zoospore release. Considering the increased interest in algae as an economic resource, [blue] carbon sink, and as ecosystem engineers, the potential for “banking” macroalgal forms could be a mechanism of resilience and recovery in aquatic populations that have complex life cycles and environmental cues for reproduction. Molecular barcoding is becoming an important tool for identifying banks of macroalgal forms in marine communities. Understanding banks of macroalgal stages, especially in deforested habitats with intense disturbance and grazer pressure, will allow researchers and marine resource managers to facilitate this natural process in recovery of the aquatic system.

重新审视以藻类为主的生态系统中的“微观形式库”

在陆地生境中定义了理论生态模型，例如演替和简化，随后将其应用于潮间带和潮下带的海洋和淡水生境。一种这样的模型是土壤种子库，定义为在土壤表面附近发现的所有有助于社区恢复/恢复的可行种子（或果实）。在水生生境中假设了“微观形式的库”，水产养殖的最新工作突出了藻类生命周期阶段的休眠。为了重振有关这些藻类库的讨论，我们讨论了生命周期，扩散方面的差异，并总结了有关水生生态系统中大型藻类库的研究，这些研究可能随着分子技术的现代发展而更容易探索。专注于全球海带森林生态系统的开创性工作，Nereocystis luetkeana和Alaria金边瑞香游动孢子释放后很长一段时间，可以使用靶向引物在海藻森林中的岩石和基岩生物膜中检测到这些阶段。考虑到对藻类作为一种经济资源，[蓝色]碳汇和生态系统工程师的兴趣日益增加，潜在的“藻类”“藻类”储存可能是具有复杂生命周期和环境线索的水生种群适应力和恢复的机制。再生产。分子条形码正在成为识别海洋群落中大型藻类库的重要工具。了解大型藻类的河岸，尤其是在强烈干扰和掠食者压力下的森林砍伐生境中，将使研究人员和海洋资源管理者能够促进这一自然过程恢复水生系统。
