Abstract

Can heritable traits in a single species affect an entire ecosystem? Recent studies show that such traits in a common tree have predictable effects on community structure and ecosystem processes. Because these 'community and ecosystem phenotypes' have a genetic basis and are heritable, we can begin to apply the principles of population and quantitative genetics to place the study of complex communities and ecosystems within an evolutionary framework. This framework could allow us to understand, for the first time, the genetic basis of ecosystem processes, and the effect of such phenomena as climate change and introduced transgenic organisms on entire communities.

摘要

单一物种的可遗传性状会影响整个生态系统吗？最近的研究表明，一种常见树木的此类性状对群落结构和生态系统过程具有可预测的影响。由于这些“群落和生态系统表型”具有遗传基础且可遗传，我们可以开始应用种群遗传学和数量遗传学原理，将复杂群落和生态系统的研究置于进化框架内。这一框架可能使我们首次了解生态系统过程的遗传基础，以及气候变化和引入转基因生物等现象对整个群落的影响。
