Leaf litter decomposer community

Microbes drive leaf litter decomposition, and their communities are adapted to reflect the local vegetation providing that litter. However, whether these local microbial communities confer a significant home-field advantage in litter decomposition remains unclear, with con-trasting results being published. Here we focus on a litter transplantation experiment from oak forests (home site) to two away sites without oak in South Tyrol (Italy).

微生物驱动叶片凋落物分解（leaf litter decomposition），其微生物群落（microbial community）组成可反映产出该凋落物的本地植被特征。然而，此类本地微生物群落是否能在凋落物分解过程中赋予显著的本土场优势（home-field advantage），目前尚无定论，且已有研究发表了相互矛盾的实验结果。本研究聚焦于一项凋落物移植实验：将源自栎林（本土样地，home site）的凋落物，移植至意大利南蒂罗尔地区的两处无栎树的异地样地。
