新模型认为,真菌和细菌会迅速破坏食物,防止其被大体型的竞争对手抢走。你有没有咬到一个烂苹果然后厌恶地扔掉它的经历?一些科学家认为,这是微生物正在向你发起细菌战,且前者获胜。40年前就有人提出,细菌和真菌“积极地”破坏食物,是为了避免大型动物(例如人类)抢夺它们的食物。然而,这一观点尚未得到检验。日前,一项新研究利用数学模型证实了这个假设的合理性。1977年,安阿伯市美国密歇根大学生态学家Daniel Janzen在一篇论文中首次提出该观点。
The new model argues that fungi and bacteria quickly destroy food and prevent it being snatched by a general competitor. Did you ever bite a rotten apple and discarded it with disgust? Some scientists think it is the microbes that are fighting a germ warfare against you and the former won. Some 40 years ago it was suggested that bacteria and fungi “destroy food aggressively” in order to prevent large animals, such as humans, from snatching their food. However, this view has not yet been tested. Recently, a new study used mathematical models to confirm the rationality of this hypothesis. In 1977, Daniel Janzen, an ecologist at the University of Michigan in Ann Arbor, put it forward for the first time in a paper.
