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

这个合作的SGER项目将立即开始对植物/传粉者互惠关系的研究，这种互惠关系很可能已经被2003年南加州的野火破坏了。研究系统包括丝兰和丝兰蛾Tegeticula maculata，它们是互惠互利的，在过去几年里在整个加州的不受干扰的条件下进行了非常好的研究。根据该项目，其中一名PIS(Udovic)将继续在圣地亚哥附近的埃利奥特·查帕拉尔保护区和圣玛格丽塔生态保护区这两个地点调查这种相互作用。2003年10月下旬，他的研究地点的一些重要部分被烧毁，而其他地点则幸免于难。对这一系统的即时和长期火灾后研究将利用火灾前同一地点的比较数据，以及同一时间段类似但未烧毁的地点的比较数据。一个目标是描绘火灾对互惠种群数量、互惠物候的影响，以及随之而来的伙伴在未来几个季节找到对方并成功繁殖的可能性。该项目的更广泛应用包括火灾预防、管理和应对方面的外联。这项工作将为两名本科生(一名来自俄勒冈大学，一名来自亚利桑那大学)提供研究机会。

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).
