We studied the changes in the wood-inhabiting fungal communities on dead wood of Scots pine (Pinus sylvestris) under varying duration and intensity of cormorant nesting. The activities of the birds created large amounts of dead wood, changed wood chemistry and altered stand characteristics. Analyses based on records of fruiting structures of fungi showed that fungal communities in the cormorant colony differed from communities in unaffected forest. Ornithogenic factors impacted least on generalist species and promoted the occurrence of fungi uncharacteristic of coniferous wood or wood in general. The rate of ornithogenic change was rapid: a shift in fungal assemblages was evident by the third year of expansion of the bird colony into unaffected forest. It featured the disappearance of tremelloid fungi, a decline of corticioid fungi and an increase of hyphomycetoid fungi. The proportion of coniferous wood specialists decreased and that of generalists increased. It is expected that the changes in fungal communities will persist until the forest is fully regenerated.

我们研究了樟子松（Pinus sylvestris）枯木上居住木材的真菌群落的变化）在不同的时间和强度下nest筑巢。鸟类的活动造成大量死木，改变了木材的化学性质，改变了林分的特性。根据真菌的果实结构记录进行的分析表明，the群落中的真菌群落与未受影响的森林中的群落不同。鸟类致病因素对通才物种的影响最小，并促进了针叶木材或一般木材的真菌特性的发生。鸟类致敏变化的速度非常快：真菌种群的变化在鸟类群落扩展到未受影响的森林的第三年就很明显。它的特征是四倍体真菌的消失，皮质类固醇真菌的减少和次霉菌真菌的增加。针叶木专家的比例下降，通才木专家的比例上升。预计真菌群落的变化将持续到森林完全再生为止。
