外来入侵植物如豆科植物（Prosopis juliflora）改变地下水吸收模式。我们测量了苏丹干旱地区豆科树林下的地下水位。地下水位的变化与植物吸水性密切相关。地下水位在日出前几个小时开始下降，在中午左右恢复，然后继续下降，直到日落后几个小时，然后在夜间再次恢复。因此，地下水位出现了两个峰值：日出前和中午前后。午间恢复是由于热和光抑制了光合作用。
Invasive alien plants such as mesquite (Prosopis juliflora) alter patterns of groundwater uptake. We measured the groundwater level beneath a mesquite stand in an arid area in Sudan. The changes in groundwater level closely followed plant water uptake. The groundwater level started to decline a few hours before sunrise, recovered around noon, and then continued to decline until a few hours after sunset, before recovering again during the night. Thus, groundwater level showed two peaks: just before sunrise and around midday. The midday recovery was due to the depression of photosynthesis by heat and light.
