三种松树之间和内部的生理特征协调与变异
摘要 研究探索了植物的性状如何在生态学上将植物区分开来,以及这种区分的基础是什么。然而,关于性状在何种分类尺度上可预测地分离物种,仍然存在不确定性。我们研究了生理特征如何将三个地点的三个松树(Pinus banksiana、Pinus resinosa 和 Pinus strobus)物种区分开来。我们从四个常见的叶片和枝条测量数据(光响应曲线、二氧化碳响应曲线、压力-体积曲线和水力脆弱性曲线)中收集了每个物种和地点的性状。虽然这些测量方法很常见,但由于后勤方面的限制,通常不会一起测量。考虑到物种的生态偏好和环境地点特征,很少有物种和地点之间的性状变化。在三个物种中观察到了一些在广泛的分类尺度上存在的性状权衡,但大多数性状在物种内部并不存在。某些权衡结果与在更大范围内观察到的预期结果不同,但根据物种的生态偏好,这些权衡结果符合预期。我们强调有必要澄清为什么要对某些性状进行研究,因为经常会出现意想不到但在生态学上有意义的变异,而且某些性状在特定品系内可能没有实质性的变化(例如松科植物的水力脆弱性),这突出了性状选择在性状生态学中的作用。

期刊介绍: New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
