通过检测林冠叶片、林下叶片和空气的碳同位素组成（∂13 C），评估了亚马逊低地雨林中靠近暴露森林边缘对植物的影响。在连续的森林中，在距5年树龄边缘100 m范围内，以及在孤立的1-ha森林碎片中，采集了异型李卡尼（Licania heteromorpha）和微冠硬化病（Scleronema microranthum）暴露的冠层叶片。沿着从5年边缘到森林内部和对照区的样带，每隔一段时间采样一次林下物种，鞭毛杜鹃（Duguetia af . flagellaris）和社会星caryum sociale。在幼林隙、林隙边缘、老林隙、未受干扰的林下和次生植被中也采集到了鞭毛草叶片。
The effects of proximity to an exposed forest edge on plants in Amazonian lowland rainforest were assessed by examining carbon isotopic composition (∂ 13 C) of canopy leaves and of understorey leaves and air. Exposed canopy leaves of Licania heteromorpha and Scleronema micranthum, were collected in continuous forest, within 100 m of a 5-year-old edge, and in isolated 1-ha forest fragments. Leaves of the understorey species, Duguetia aff. flagellaris and Astrocaryum sociale, were sampled at intervals along transects from a 5-year-old edge towards the forest interior and in control areas. Leaves of D. flagellaris were also collected from young gaps, gap edges, old gaps, undisturbed understorey and from secondary vegetation (...)
