Population dynamics and genetic variation of plants with contrasting fire responses

不同火反应植物的种群动态和遗传变异。我们结合了联合收割机的人口生活力分析的传统关注与DNA指纹的精确基因分型的个体植物和它们的种子的现代技术。我们期待着重大突破，我们的理解如何火灾死亡的物种生存了数千年的频繁燃烧的土著人（通过识别从被烧毁的父母分散的长距离的种子）;后代的父系如何在保留其种子多年的植物的寿命中变化;植物内遗传变异在什么年龄达到最大，作为最佳火灾管理的指导;以及有害的体细胞突变解释了长寿物种的低结实率。

Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.
