芒萁是一种常见的蕨类植物，分布于世界各地的热带和亚热带地区。它通常形成一个垫状林下，特别是在开放的地区。以芒萁属植物为主的林下植被在生态系统动态中具有重要作用，但在生态学研究中却常常被忽视。通过去除林下和林上芒萁，比较了它们对土壤小气候、凋落物分解、土壤分解者食物网和生态系统养分循环的影响。我们的实地研究结果表明，去除Dicranopteris占主导地位的林下植被导致土壤温度升高，土壤湿度降低，随后，改变土壤食物网的组成部分（微生物群落，线虫和microarthropod密度）和减少凋落物分解的生态系统过程。芒萁在亚热带和热带地区形成了一个密集的林下植被层，有利于维持土壤小气候，并在集约森林生态系统中充当土壤生物群和生态过程的主要驱动力。
Dicranopteris is a common fern distributed throughout tropical and subtropical regions of the world. It often forms a mat-like understory, especially in open areas. A forest floor dominated by Dicranopteris plays an important role in ecosystem dynamics, but is often overlooked in ecological research. We conducted an experiment by removing overstory or understory Dicranopteris to compare their effects on soil microclimate, litter decomposition, soil decomposer food web and ecosystem nutrient cycling. Results of our field study showed that removal of a Dicranopteris-dominated understory leads to increased soil temperature and reduced soil moisture, subsequently, altering the components of the soil food web (microbial community, nematode and microarthropod densities) and reducing ecosystem processes of litter decomposition. When present, Dicranopteris forms a dense understory layer in subtropical and tropical regions, which is favorable for sustaining soil microclimates and acts as the major driver of soil biota and ecological processes in intensive forest ecosystems.
