Collaborative Research: SGER: Post-fire Recovery of a Plant-pollinator Mutualism

这个协同SGER项目将立即开始研究植物/传粉者的共生关系，这种共生关系很可能被2003年南加州的野火破坏了。该研究系统包括丝兰（Hesperoyucca whipplei）和丝兰蛾（Tegeticula maculata），它们是共生植物，在过去几年里，它们在加利福尼亚州的未受干扰的条件下得到了非常好的研究。在这个项目中，其中一位pi （Udovic）将继续在圣地亚哥附近的两个地点——艾略特Chaparral保护区和圣玛格丽塔生态保护区——调查这种相互作用。2003年10月下旬，他的研究地点的一些重要部分被烧毁，而其他部分幸免于难。该系统火灾后的即时和长期研究将利用火灾前同一地点的比较数据，以及同一时期内类似但未燃烧的地点的比较数据。一个目标是描述对共生种群规模、共生物候的影响，以及由此产生的伴侣在未来季节找到彼此并成功繁殖的可能性。该项目的更广泛应用包括防火、管理和应对方面的推广。这项工作将为两名本科生提供研究机会（一名来自俄勒冈大学，一名来自亚利桑那大学）。

This Collaborative SGER project would begin the immediate study of a plant/pollinator mutualism that, most likely, has been disrupted by the 2003 wildfires in southern California. The study system includes the yucca Hesperoyucca whipplei and yucca moth Tegeticula maculata, which are mutualists, which have been exceptionally well studied in undisturbed conditions throughout California over the last several years. Under this project, one of the PIs (Udovic) would continue investigating this interaction at two sites near San Diego, the Elliot Chaparral Reserve and the Santa Margarita Ecological Reserve. In late October 2003, some significant portions of his study sites burned while others escaped damage. The immediate and longer-term post-fire study of this system would take advantage of comparative data from the same site before the fire, and from a similar but unburned site over the same time period. One goal is to delineate fire impacts on mutualist population sizes, mutualist phenologies, and the consequent likelihood that the partners will locate each other and reproduce successfully in the coming seasons. The broader applications of the project include outreach on fire prevention, management and response. This work will provide research opportunities to two undergraduate students (one from University of Oregon and one from University of Arizona).
