Nutrients and temperature additively enhance microbial respiration from decomposing wood

Fungi are primary decomposers, but the impact of human-induced changes in temperature and nutrients on fungal communities and its consequences for wood microbial respiration are not well understood. Here, we combined field and laboratory experiments to examine how nutrient additions and temperature increases would affect the links between fungal communities and microbial respiration and its temperature dependence from decomposing angiosperm and gymnosperm woods.

真菌是陆地生态系统中的主要分解者，但人类活动驱动的温度与养分变化对真菌群落的影响，及其对木材微生物呼吸作用的连锁效应，目前尚未得到充分阐明。本研究结合野外原位实验与室内控制实验，探究养分添加与升温将如何影响分解过程中被子植物（angiosperm）与裸子植物（gymnosperm）木材内的真菌群落与微生物呼吸之间的关联，以及该关联的温度依赖性。
