跨越环境梯度的植物拮抗促进作用:土壤资源生态系统工程模型。
理论质疑非互惠互动的持续性,在这种互动中,一种植物对邻近植物产生正净影响,而邻近植物对其受益者产生负净影响--这种现象被称为拮抗促进。我们建立了一个空间明确的消费者-资源模型,用于生态系统工程师(能够开采资源并将资源提供给群落中任何其他植物的植物)与开发者之间的地下植物竞争。我们利用该模型来确定在什么样的环境条件下,通过土壤资源工程的拮抗促进作用会成为最优策略。拮抗促进作用出现在压力环境中,在这种环境中,生态系统工程师从开采资源中获得的自身利益超过了与机会主义邻居的竞争。在模型中考虑的所有潜在压力原因中,驱动植物间互动变化的关键环境参数是在没有任何开采活动的情况下,植物可随时消耗的资源比例。我们的研究结果与原生演替理论和压力梯度假说相吻合。然而,我们发现根系生物量总量及其在根系中的空间分配(通常用于衡量植物间相互作用的符号)并不能可靠地预测促进作用。

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.
