关键信息树种在单个树木的尺度上功能不同，这将导致生态系统服务提供的差异。病树的替代树应考虑功能差异。AbstractGlobally树种组成正在发生变化，由于物种损失的害虫和病原体。这种变化对生态功能的影响很少得到检验。在英国使用六个站点，每个站点有多个树种，我们测试了英国三个受疾病威胁的物种之间的功能差异：其他6个种：槭（Acer pseudoplatanus）、栗（Castanea sativa）、水青冈（Fagus sylvatica）、赤栎（Quercus cerris）、红栎（Quercus rubra）和欧洲椴（Tilia x europaea），这些种以前被认为是生态替代物。物种之间的差异进行了检测，所有测量的变量：氮矿化，分解速率，土壤总碳和氮，土壤pH值，土壤温度，树皮持水量。非nativeQuercusspecies只适合替代nativeQuercus的一些功能测量，但复制nativeQuercus功能使用其他物种的混合物可能是可能的。F的功能。Excelsior与大多数其他树种不同，这表明用替代树种复制其功能是困难的。这项工作强调，哪种物种取代病树，即使是在单棵树的规模上，也会影响所提供的功能和生态系统服务。
Key messageTree species differ in their functioning at the scale of an individual tree which will result in differences in ecosystem service provision. Replacement trees for diseased trees should take account of functional differences.AbstractGlobally tree species composition is changing due to species loss from pests and pathogens. The impact of this change on ecological functioning is rarely tested. Using six sites across the UK, with multiple tree species at each site, we test for functional differences between three species threatened by disease in the UK:Quercus petraea,Q. roburandFraxinus excelsiorand six other species:Acer pseudoplatanus,Castanea sativa,Fagus sylvatica,Quercus cerris,Quercus rubra,andTilia x europaea, which have previously been suggested as ecological replacements. Differences between species were detected for all the variables measured: nitrogen mineralization, decomposition rate, total soil carbon and nitrogen, soil pH, soil temperature, and bark water holding capacity. Non-nativeQuercusspecies were only suitable replacements for nativeQuercus for some of the functions measured but replicating nativeQuercus functioning using a mixture of other species may be possible. The functioning ofF. excelsiorwas different from most other tree species, suggesting that replicating its functioning with replacement tree species is difficult. The work highlighted that which species replaces diseased trees, even at the scale of single trees, will impact on the functions and ecosystem services provided.
