Saproxylic beetles in high stumps of spruce: Fungal flora important for determining the species composition

摘要: In most Swedish felling operations high stumps are created from living trees to increase the amounts of dead wood in forest. The fauna saproxylic beetles and aradid bugs (Heteroptera) spruce (Picea abies) were studied determine which characteristics (diameter, height, amount bark fungal flora) had strongest influence on species composition. practical aim was see whether it is possible biodiversity values by management recommendations. (n=59) situated middle boreal zone Sweden 6 years old. insects sampled sieving 0.25 m2 each stump total, 803 Aradus found, representing 42 different species, five red-listed. important factor for determining beetle community presence or absence two polyporous fungi, Fomitopsis pinicola Trichaptum abietinum. Other factors much less important, indicating that difficult...
