Abstract Here, we have presented a field device for sampling periphyton in lentic systems, with a tropical lowland wetland in Colombia as the model system. The periphyton sampler (PS) is composed of a central soft iron pole to which rectangular woody boxes and glass slides are attached to lateral iron axes, which can be distributed at different depths. Our PS can be used to evaluate changes in the richness and density of algal communities at different scales as well as in water quality studies.

一种评估热带浅湿地附着生物定植动态的实用装置

摘要 在这里，我们以哥伦比亚的热带低地湿地为模型系统，提出了一种用于在慢速系统中对附生生物进行采样的现场设备。附生生物采样器 (PS) 由中央软铁杆组成，矩形木箱和玻璃滑梯连接到横向铁轴上，可分布在不同深度。我们的 PS 可用于评估不同尺度以及水质研究中藻类群落丰富度和密度的变化。
