This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.

这项工作将有助于评估最佳火灾管理做法，使土地管理人员能够将目前的火灾做法与保护遗传资源所需的做法进行比较。我们对具有不同生活史属性的物种间长距离种子传播（LDD）的定量研究将为种群生态学和种群遗传学领域的研究提供重要的理论依据。如果物种要在模拟气候变化情景下预测的主要气候变化中生存下来，LDD也是必不可少的——没有有效LDD的物种可能更有可能因气候变化而灭绝。评估LDD能够量化气候变化对生物多样性威胁的这一重要方面。
