根相关真菌是生态系统功能的关键贡献者，然而，决定群落组装的因素仍然相对知之甚少。本研究同时量化的地理距离，环境异质性和时间的作用，在确定根相关真菌群落组成在本地规模内的短轮伐期矮林（SRC）杨柳种植园。文化独立的根相关的真菌群落的分子分析表明，在当地的地理水平上的组成真菌群落之间的地理距离的影响很强，但时间上可变的。虽然这些距离的影响是最普遍的10月社区，土壤pH值结构的社区在整个采样期间的影响。考虑到地理距离和环境对根相关真菌群落形成的影响的时间变化，在未来的真菌生态学调查中，显然需要一个时间组成部分的采样策略。
Root-associated fungi are key contributors to ecosystem functioning, however, the factors which determine community assembly are still relatively poorly understood. This study simultaneously quantified the roles of geographical distance, environmental heterogeneity and time in determining root-associated fungal community composition at the local scale within a short rotation coppice (SRC) willow plantation. Culture independent molecular analyses of the root-associated fungal community suggested a strong but temporally variable effect of geographical distance among fungal communities in terms of composition at the local geographical level. Whilst these distance effects were most prevalent on October communities, soil pH had an effect on structuring of the communities throughout the sampling period. Given the temporal variation in the effects of geographical distance and the environment for shaping root-associated fungal communities, there is clearly need for a temporal component to sampling strategies in future investigations of fungal ecology.
