简介:森林的阿什授精把营养素还给森林生态系统并且在土壤上有积极效果pH,而是它可以也提高森林生物区系的Cd集中。在二个阴谋与木头灰被使肥沃的地方,一些森林昆虫(从腐烂的木头的福米加蚂蚁,carabids和甲虫类之昆虫幼虫)的镉集中在南部的芬兰被调查,当二个另外的阴谋代表了未受精的控制阴谋时。在蚂蚁,吝啬的Cd集中是3.6±1.4mg/kg,与巢,比工人有显著地更高的集中的工人在陷井陷井套住。集中在使肥沃,未受精的阴谋是类似的。在carabid甲壳虫,Carabusglabratus的平均Cd集中是0.44±0.36mg/kg,没有控制阴谋和使肥沃的阴谋之间的重要差别。在另一carabid甲壳虫,Pterostichus尼日尔,吝啬的Cd集中在与控制阴谋相比的使肥沃的阴谋是更高的。我们断定在学习的昆虫的Cd集中的变化被种类特定的差别更高效地比森林地板的授精历史控制。
