The Ecological Importance of Allelopathy
Annual Review of Ecology, Evolution, and Systematics ( IF 11.2 ) Pub Date : 2021-11-03 , DOI: 10.1146/annurev-ecolsys-051120-030619

Allelopathy (i.e., chemical interaction among species) was originally conceived as inclusive of positive and negative effects of plants on other plants, and we adopt this view. Most studies of allelopathy have been phenomenological, but we focus on studies that have explored the ecological significance of this interaction. The literature suggests that studies of allelopathy have been particularly important for three foci in ecology: species distribution, conditionality of interactions, and maintenance of species diversity. There is evidence that allelopathy influences local distributions of plant species around the world. Allelopathic conditionality appears to arise through coevolution, and this is a mechanism for plant invasions. Finally, allelopathy promotes species coexistence via intransitive competition, modifications of direct interactions, and (co)evolution. Recent advances additionally suggest that coexistence might be favored through biochemical recognition. The preponderance of phenomenological studies notwithstanding, allelopathy has broad ecological consequences.

化感作用的生态重要性

化感作用(即物种间的化学相互作用)最初被认为包括植物对其他植物的正面和负面影响,我们采用这种观点。大多数化感作用的研究都是现象学的,但我们专注于探索这种相互作用的生态意义的研究。文献表明,化感作用的研究对生态学的三个焦点特别重要:物种分布、相互作用的条件和物种多样性的维持。有证据表明化感作用会影响世界各地植物物种的局部分布。化感条件似乎是通过共同进化产生的,这是植物入侵的一种机制。最后,化感作用通过不及物竞争、直接相互作用的改变、和(共同)进化。最近的进展还表明,通过生化识别可能有利于共存。尽管现象学研究占优势,但化感作用具有广泛的生态后果。
