“The fallen petals are not as cruel as they seem; they fertilise those in full bloom instead.” ‐ Gong Zizhen (Qing Dynasty). This issue’s cover shows Hypholoma fungus growing on a decaying log in Pacific Spirit Regional Park, Canada. Both bark and wood decomposition are vital processes in global carbon and nutrient cycles, and the ability to accurately estimate the decay rates of each log component is important. In their article, Chang et al. present a user‐friendly method for quantifying bark and wood volume loss during decomposition, and percentage reduction of bark cover. Results can be compared with those based on the prevalent decay class classification method, making it possible to understand woody debris decay dynamics across species at regional and global scales.

“落下的花瓣并不像看起来那样残酷；他们为那些盛开的植物施肥。” 龚自珍（清朝）。本期杂志的封面显示在加拿大太平洋精神地区公园的腐烂的原木上生长的hypholoma真菌。树皮和木材的分解都是全球碳和养分循环中的重要过程，因此准确估算每个对数成分的衰减速率的能力很重要。在Chang等人的文章中。提供了一种用户友好的方法，用于量化分解过程中的树皮和木材体积损失，以及减少树皮覆盖的百分比。可以将结果与基于普遍的腐烂类别分类方法的结果进行比较，从而有可能了解区域和全球范围内物种间木屑的腐烂动态。
