Virot et al. [E. Virot et al., Phys. Rev. E 93, 023001 (2016)10.1103/PhysRevE.93.023001] assert that the critical wind speed at which ⩾50% of all trees in a population break is ≈42 m/s, regardless of tree characteristics. We show that empirical data do not support this assertion, and that the assumptions underlying the theory used by Virot et al. are inconsistent with the biomechanics of trees.
维罗特等人[E. 维罗特等人,《物理评论E》93,023001(2016年)10.1103/PhysRevE.93.023001]断言,无论树木特征如何,种群中50%以上的树木折断时的临界风速约为42米/秒。我们表明,经验数据不支持这一断言,而且维罗特等人所使用理论的基础假设与树木生物力学不一致。
