The influence of propagule banks on demography and genetic diversity in freshwater invertebrates and plants.

我们的目标是通过结合实证和建模的方法来了解繁殖库如何对人口和遗传多样性做出贡献。在苔藓虫和植物系统中，沉积物结合繁殖体和不同年份群体的遗传结构将被表征。模型将预测基因型频率的时间变化以及由繁殖体库产生的比例。阶段结构模型模拟将确定影响人口统计的关键参数。我们的研究将对浮游动物、植物和微生物等分类群的时间基因流动的生态意义具有广泛的意义，并为表征繁殖体库的人口贡献提供了机制基础。

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.
