气候变化影响着各种时空尺度的生态系统，扰乱了常驻生物的生命周期。人们对蘑菇生产力和物候的环境驱动因素知之甚少，部分原因是真菌的生命周期主要在地下。在这里，我们提出了一个实地调查的结果，其中共有65 631独特的个人菌根蘑菇-代表273种-记录在每周的时间间隔从1975年至2006年在瑞士的自然保护区。平均年出菇量由1991年前的1313株增加到1991年及以后的2730株，但平均出菇时间比1991年推迟10天。沉淀量和温度意味着测定的真菌活性。重建20世纪至当代瑞士葡萄酒收获日期的蘑菇结果年内时间，为气候引起的生态系统变化提供独立证据。从社会经济和生态角度来看，增强的生长条件和延长的生长季节似乎对真菌有益，因为大多数维管植物与菌根真菌相互作用以产生生物量。
Climate change affects ecological systems across various spatiotemporal scales and disrupts the life cycles of resident organisms. Little is known about the environmental drivers of mushroom productivity and phenology, partially because the life cycle of fungi is mostly belowground. Here, we present results from a field survey, in which a total of 65 631 unique individual mycorrhizal mushrooms - representing 273 species - were recorded during weekly intervals from 1975 to 2006 in a nature reserve in Switzerland. The average annual number of observed mushrooms increased from 1313 (pre-1991) to 2730 (1991 and thereafter), while average fruiting time during the latter period was delayed by 10 days as compared with that of the former. Precipitation amounts and temperature means determined fungal activity. Reconstructed intra-annual timing of mushroom fruiting for the 20th century paralleled contemporary Swiss wine harvest dates, providing independent evidence of climate-induced ecosystem change. Enhanced growth conditions and extended growing seasons appear beneficial to fungi from both a socioeconomic and an ecological perspective, because most vascular plants interact with mycorrhizal fungi to generate biomass.
