We aim to understand how propagule banks contribute to demography and genetic diversity through a combined empirical and modelling approach. The genetic structure of sediment bound propagules and of populations from different years will be characterized in bryozoan and plant systems. Models will predict temporal changes in genotype frequencies and the proportions deriving from propagule banks. Stage structured model simulations will identify key parameters that influence demography. Our study would have broad implications regarding the ecological significance of temporal gene flow in taxa ranging from zooplankton and plants to microbes, and a mechanistic basis for characterizing demographic contributions from propagule banks.

我们的目标是了解繁殖体银行有助于人口和遗传多样性，通过结合经验和建模方法。沉积物绑定繁殖体和不同年份的人口的遗传结构将在苔藓动物和植物系统的特点。模型将预测基因型频率的时间变化和繁殖体库的比例。阶段结构模型模拟将确定影响人口统计的关键参数。我们的研究将有广泛的影响，从浮游动物和植物到微生物的类群的时间基因流的生态意义，以及从繁殖体银行的人口统计学贡献的特征的机械基础。
