Dissertation Research Pollinator Mediated Plant

项目摘要

Silene alba, a flowering plant found along roadsides, can become infected with a parasitic disease, caused by a fungus. In addition to rendering the plants sterile, this disease causes both male and female plants to produce flowers with anther sacs filled with spores of the fungus. The insects which pollinate healthy Silene alba also visit diseased flowers, thus acting as vectors of this disease. This study attempts to show how the behavior of the insect pollinator/vector influences the plant-pathogen interaction between Silene alba and the fungus by using an approach which combines field observations, experimentation, and mathematical modeling. No studies of plant-vector-pathogen interactions have included the behavioral component of the vector in modeling the dynamics of the system. This study in which the disease vector is also the pollinator of the plant is an ideal place to begin an investigation of how vector behavior affects a plant-pathogen interaction. The voluminous literature on the effect of pollinator behavior on plant population dynamics can be drawn upon to develop models in this plant-pollinator/vector-pathogen interaction. The results of this study will be of interest to epidemioligists working in plant-vector-pathogen systems as well as to evolutionary ecologists working on the effects of individual behavior on population and community dynamics.

Silene alba 是一种路边开花植物，可能会感染由真菌引起的寄生虫病。除了使植物不育之外，这种疾病还会导致雄性和雌性植物产生带有充满真菌孢子的花药囊的花朵。为健康的 Silene alba 授粉的昆虫也会访问患病的花朵，从而成为这种疾病的媒介。本研究试图通过结合实地观察、实验和数学建模的方法，展示昆虫传粉媒介/媒介的行为如何影响 Silene alba 和真菌之间的植物-病原体相互作用。没有关于植物-载体-病原体相互作用的研究在系统动力学建模中包括载体的行为成分。这项研究中，病媒也是植物的传粉媒介，是开始研究病媒行为如何影响植物与病原体相互作用的理想场所。关于传粉媒介行为对植物种群动态影响的大量文献可以用来开发植物-传粉媒介/媒介-病原体相互作用的模型。这项研究的结果将引起研究植物-媒介-病原体系统的流行病学家以及研究个体行为对种群和群落动态影响的进化生态学家的兴趣。
