Lava flows create new, initially sterile habitats. The identity of the initial colonizers of these habitats, subsequent invaders, and the repeatability of this process is important for understanding the establishment of ecosystem processes like nutrient cycling. Identifying steps in habitat maturation also shapes conservation strategies for endangered species and rare environments. These processes are virtually unknown in the anchialine ecosystem, which consists of coastal, landlocked bodies of water influenced by fresh and oceanic waters. Anchialine habitats are rare worldwide but are concentrated in Hawaii. Hawaiian anchialine habitats are home to a diverse array of animals, plants, and microbes, many of which are found nowhere else. In 2018 lava flows from the Kilauea volcano created several new anchialine habitats on the east coast of Hawaii, presenting an exceptional chance to examine how ecology emerges in the anchialine ecosystem. The researchers will leverage this opportunity to detail how these unusual habitats change over time. Microbial and animal communities will be characterized as they become established. This research will advance our understanding of the anchialine ecosystem, especially its microbes, which may prove useful for future medical or commercial applications. Underrepresented groups in STEM (including native Hawaiians and Pacific Islanders) will take an active role in this research. Hundreds of microbial samples will be collected during a time series in anchialine habitats undergoing development. Microbial community structure will be analyzed using DNA sequencing technology. These “young” communities will be compared to ones previously characterized from other, “mature” Hawaiian anchialine habitats. This research will address the repeatability of anchialine community formation and whether new habitats are converging on microbial communities similar to those in established habitats. To complement these microbial analyses, presence and abundance of a keystone shrimp species in the new anchialine habitats will also be assessed. Population genomic tools will be used to test the origins of the colonizing shrimp, as the lava flows may have caused local extinctions in this species. Physiological experiments in shrimp will also be performed to examine thermal adaptations stemming from elevated temperatures due to volcanic activity. Because shrimp act as important grazers on the microbial communities, correlations between shrimp abundance and microbial community composition will also be explored.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

熔岩流创造了新的、最初贫瘠的栖息地，这些栖息地的最初殖民者、随后的入侵者的身份以及这一过程的可重复性对于理解生态系统过程（如养分循环）的建立非常重要，识别栖息地成熟的步骤也可以制定保护策略。这些过程在安奇阿林生态系统中几乎是未知的，该生态系统由受淡水和海洋水域影响的沿海内陆水体组成，安奇阿林栖息地在世界范围内很少见，但集中在夏威夷：夏威夷的安奇阿林栖息地是多种动物、植物和微生物的家园，其中许多是在其他地方找不到的。2018 年，来自基拉韦厄火山的熔岩流在夏威夷东海岸创造了几个新的安奇阿林栖息地，呈现出独特的环境。研究人员将利用这个机会来详细了解这些不寻常的栖息地随着时间的推移将如何变化。增进我们对 anchialine 生态系统，特别是其微生物的了解，这可能对未来的医疗或商业应用有用。 STEM 中代表性不足的群体（包括夏威夷土著和太平洋岛民）将在这项研究中发挥积极作用。在正在开发的 anchialine 栖息地的时间序列中收集的微生物群落结构将使用 DNA 测序技术进行分析，这些“年轻”群落将与之前从其他“成熟”夏威夷 anchialine 中表征的微生物群落进行比较。这项研究将解决 anchialine 群落形成的可重复性，以及新栖息地是否与已建立的栖息地相似的微生物群落趋同，为了补充这些微生物分析，还将研究新的 anchialine 栖息地中关键虾种的存在和丰度。种群基因组工具将用于测试殖民虾的起源，因为熔岩流可能导致该物种的局部灭绝，还将进行虾的生理实验以检查热适应能力。由于火山活动导致气温升高，虾是微生物群落的重要食草动物，因此还将探讨虾丰度与微生物群落组成之间的相关性。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
