Understanding the Factors that Govern Invasion (and coexistence), a Case Study with an Anomalous Asian Ant.

OISE-0809267(北卡罗来纳州立大学邓恩分校)《了解支配入侵(和共存)的因素：一种异常亚洲蚂蚁的案例研究》摘要该奖项支持PI和两名研究生计划访问日本冈山，与松浦健二教授？S社会昆虫工作组建立一个合作研究项目。合作的重点是了解促进物种入侵的因素，以及入侵物种在其原生和引进范围内生活史的差异，特别是对中国粗尖线虫的关注。中国对虾早在1903年就从东亚传入美国东部。虽然长期以来一直没有人注意到，但该物种的活动范围已经扩大，现在从佛罗里达到纽约都可以找到，在一些地区显示出主导当地蚂蚁聚集的迹象。与大多数入侵蚂蚁物种不同，中国对虾没有热带起源。它的原生和入侵栖息地在物种丰富度上相似，并共享许多属。在入侵的地方，它既可以生活在受干扰的栖息地，也可以生活在未受干扰的栖息地。因此，中国粗毛虫是规则的一个有趣的例外？为入侵蚂蚁提供了一个新的机会来了解蚂蚁的生物入侵行为。在计划于2008年夏天进行的访问期间，该团队将访问冈山周围潜在的野外地点，比较现有结果，并设计一系列实验。

OISE-0809267 (Dunn, North Carolina State University)"Understanding Factors that Govern Invasion (and coexistence): A Case Study with an Anomalous Asian Ant"AbstractThis award supports a planning visit to Okayama, Japan by the PI and two graduate students to build a collaborative research program with Professor Kenji Matsuura?s social insect working group. The collaboration focuses on understanding the factors that facilitate invasion of species and differences in life history of invasive species in their native and introduced ranges, with particular focus on Pachycondyla chinensis. P. chinensis was introduced into the eastern U.S. from East Asia as early as 1903. While long unnoticed, the species has expanded its range and can now be found from Florida to New York, showing signs in some areas of dominating local ant assemblages. In contrast to most invasive ant species, P chinensis does not have tropical origins. Its native and invaded habitats are similar in species richness and share many genera. Where invasive, it can inhabit both disturbed and undisturbed habitats. Thus, pachychondyla chinensis is an interesting exception to ?the rules? for invasive ants and offers a novel opportunity to understand biological invasions by ants. During the planning visit, scheduled for summer 2008, the team will visit potential field locations around Okayama, compare existing results, and design a series of experiments.
