摘要

我们描述了一种方法来测量在入侵的早期阶段，在一个浅营养不良的蓄水池的异型狐尾藻（可变叶水千叶）的入侵。在8周的观测期内，干重测量结果显示，其生物量比增长率为0.0048·day - 1，与其他研究结果一致，其扩散速率（生物量扩散）为D = 9.2 cm2·D - 1，描述了对无植物沉积物的水平侵入。

A technique to monitor growth and spread of early-stage variable-leaf watermilfoil in a shallow impoundment

We describe an approach to measure the invasiveness of Myriophyllum heterophyllum (variable leaf watermilfoil) in a shallow dystrophic impoundment at the early stages of an invasion. Over an eight-week observation period, dry weight measurements show a biomass specific rate growth rate of 0.0048·day⁻¹, consistent with other studies of invasive watermilfoil growth, and a diffusion rate (biomass spread) of D = 9.2 cm²·d⁻¹, which describes the horizontal encroachment into plant-free sediment.
