On September 11, 1992, Hurricane Iniki, the most powerful hurricane to hit the State of Hawaii this century, struck the Island of Kauai with steady wind speeds of over 230 km/hr and gust over 280 km/hr. Everything in the path of the hurricane was profoundly transformed; homes, public building, hotels, agricultural crops, and the natural features of the island were severely damages or destroyed. An aerial survey by the State Division of Forestry and Wildlife described the vegetation of the mountains as being "mowed by a giant weed-eater" This event presents a once-in-a-century opportunity to study the consequences of such a phenomenon for the natural environment of the Hawaiian Islands. Prior research on Kauai will, in some cases, provide a baseline from which to measure changes wrought by the hurricane and track subsequent responses as t he ecosystems adjust to its short, medium and long-term consequences. The research proposed her seeks to measure the immediate effects of the hurricane and to monitor the ongoing consequences of this natural phenomenon. Of particular interest are the genetic effects of a population flush of some organisms, e.g. some species in the insect family Drosophilidae, in response to a huge but temporary increase in decaying organic mater. The population explosion may followed by a long period of small population size as the decaying material diminish and since it may be months or even years before some of the vegetation is restored to pre-hurricane conditions. Understand the genetics consequences of the sudden increase in population size followed by an extended period of small population size is important for understanding the ability of populations to survive catastrophic environmental conditions. Dr. Kaneshiro will also monitor population levels of exotic drosophilid species which have been shown to be a good indicator for disturbed habitats. As exotic fruit plants invade the now open forest, an increase is expected in exotic drosophilid species which are associate with the exotic plants. As the native forest canopy recovers and is restored to pre-hurricane conditions, a decrease in populations size of endemic drosophilids should occur. The results of the research here would therefore further document the significance of the drosophilids as an important indicator species group for monitoring the relative health of Hawaii native ecosystem. //

1992年9月11日，1992年9月11日， 本世纪袭击夏威夷州的飓风袭击了 考艾岛，稳定风速超过230公里/小时， 阵风超过280公里/小时。飓风路径上的一切都是 深刻地改变了;家庭，公共建筑，酒店， 农业作物，以及岛上的自然特征， 严重损坏或毁坏。 国家进行的一次航空测量 林业和野生动物司描述了 山被“一个巨大的食草动物割”这一事件 提供了一个百年一遇的机会来研究 这种现象对自然环境的影响， 夏威夷群岛 在某些情况下，之前对考艾岛的研究将 案例，提供了一个基线，从该基线可以衡量所产生的变化 并跟踪随后的反应， 生态系统适应其短期、中期和长期 后果 研究建议她寻求衡量直接的 飓风的影响，并监测持续的后果 这一自然现象。 特别感兴趣的是 某些生物的种群数量激增的遗传效应，例如： 果蝇科中的一些物种， 腐烂的有机物的大量但暂时的增加。 的 人口爆炸可能会伴随着一个长期的小规模 人口规模随着腐烂的物质减少，因为它 可能需要几个月甚至几年的时间， 恢复到飓风前的状态。 了解遗传学 人口规模突然增加的后果随之而来 人口规模小的时期对于 了解人类在灾难中生存的能力 环境条件 金城博士还将监测人口水平的外来 果蝇种类已经被证明是一个很好的指示剂， 栖息地受到干扰。 当外来的水果植物入侵 开阔的森林里，外来果蝇的数量预计会增加 与外来植物有关的物种。 为 原生森林树冠恢复，并恢复到飓风前的水平 条件下，减少流行病的人口规模 果蝇应该出现。 这里的研究结果 因此，将进一步记录 果蝇作为一个重要的指示物种组， 监测夏威夷本土生态系统的相对健康状况。 //
