LTREB: Long-term Demography of Florida Scrub Plants

自1988年以来，阿赫博尔德生物站的工作人员收集了10个佛罗里达灌木物种的数千种植物的人口统计和生态数据，以回答基本的生态问题。其中包括种群生存能力是否受种群规模和火灾制度的影响，长期种群动态和灭绝是否受环境随机性和罕见事件的控制，长期趋势是否可以从短期数据中预测，以及集合种群的持久性是否可能即使当地动态不稳定。佛罗里达灌木种群进行了研究，在过去的10年中定期使用一致的测量，总结生存，生长，繁殖力和招聘人口建模中使用的数据。这项研究与遗传学、育种系统、授粉、种子休眠和微生境要求的深入调查相结合。这些植物数据集是长期的，比大多数其他用于模拟种群生存能力的研究考虑更多的种群。这些长期的数据集可以表征环境的随机性，在建模种群生存能力和灭绝的基本。从一些人口的数据收集量化的人口变化方面的微生境和自然干扰制度（火），并允许通过火灾周期和跨集合种群的人口生存能力建模。

Among these are whether population viability is affected by population size and fire regimes, whether long-term population dynamics and extinction are controlled by environmental stochasticity and rare events, whether long-term trends can be predicted from shorter-term data, and whether metapopulation persistence is likely even of local dynamics are unstable. Florida scrub populations have been studied at regular intervals over the last 10 years using consistent measurements, resulting in data summarizing survival, growth, fecundity, and recruitment for use in population modeling. This research has been coupled with intensive investigations of genetics, breeding systems, pollination, seed dormancy and microhabitat requirements. These plant data sets are longer-term and consider more populations than most other studies used to model population viability. These long term data sets allow characterization of environmental stochasticity, essential in modeling population viability and extinction. Data collection from a number of populations quantifies demographic variation with respect to microhabitat and the natural disturbance regime (fire) and allows modeling of population viability through the fire cycle and across metapopulations.
