项目摘要

This three-year award supports U.S.-France cooperative research in ecology between Doyle B. McKey, University of Miami, and Finn Kjellberg, at the Center for Ecology and Evolutionary Ecology, Montpellier, France. The objective is to study interactions in one of the classic cases of insect-plant coevolution: figs and pollinating wasps. For fig/wasp mutualism to persist, the pollinator wasps require flowering trees year-round as in tropical environments. The investigators address fig/wasp mutualism in potentially destabilizing seasonal environments as in more northern, subtropical climes found in Florida and mediterranean France. They will conduct parallel experiments to characterize wasp response to phenology, receptivity of individual figs and wasp behavior and chemical attraction to figs. The collaborative arrangements enable the investigators to pool complementary expertise and obtain comparable results. Both Miami and Montpellier are ideal locations to investigate the responses of fig/wasp mutualism to seasonal constraints. Because fig/wasp mutualism is a model system for studying many questions about co-evolution, the results from this study will make a major contribution to co-evolutionary studies in general.

这个为期三年的奖项支持美国-法国迈阿密大学 Doyle B. McKey 和法国蒙彼利埃生态与进化生态学中心 Finn Kjellberg 之间的生态学合作研究。目的是研究昆虫与植物共同进化的经典案例之一：无花果和授粉黄蜂的相互作用。为了使无花果/黄蜂互利共生得以持续，传粉黄蜂需要像在热带环境中一样全年开花的树木。研究人员解决了无花果/黄蜂在可能不稳定的季节性环境中的互利共生问题，例如在佛罗里达州和法国地中海地区发现的更北部的亚热带气候。他们将进行平行实验，以表征黄蜂对物候的反应、个体无花果的接受性、黄蜂的行为以及对无花果的化学吸引力。合作安排使研究人员能够汇集互补的专业知识并获得可比较的结果。迈阿密和蒙彼利埃都是研究无花果/黄蜂互利共生对季节限制的反应的理想地点。由于无花果/黄蜂互利共生是研究共同进化许多问题的模型系统，因此这项研究的结果将对一般共同进化研究做出重大贡献。
