Selective replacement between species of wood-rotting basidiomycetes, a laboratory study

Influence of butt rot on beetle diversity in artificially created high-stumps of Norway spruce

“…None of them, however, seemed to be affected by the presence of Heterobasidion. It is known that many wood decomposing fungi species follow a certain successional pattern (Niemelä et al, 1995;Holmer et al, 1997). This probably does not apply to Heterobasidion spp.…”

“…As it is economically beneficial to make high-stumps of low quality trees, a large proportion of the high-stumps would be made from Heterobasidion infected spruce trees. Studies on fungal succession in general, however, have shown that the primary decay fungus that first colonises the wood will determine the future fungal and beetle succession to a large extent (Kaila et al, 1994;Jonsell and Nordlander, 1995;Okland et al, 1996;Holmer et al, 1997;de Jong et al, 2004;Lindhe et al, 2004;Jonsell et al, 2005). The latter because many saproxylic beetle species are associated to a specific fungus rather than to specific wood properties (Kaila et al, 1994;Jonsell and Nordlander, 1995;Okland et al, 1996;de Jong et al, 2004;Lindhe et al, 2004;Jonsell et al, 2005).…”

Variable response of different functional groups of saproxylic beetles to substrate manipulation and forest management: Implications for conservation strategies

“…One year later, we checked the success of the inoculation by taking cores 10 cm from the places for inoculation on 10 randomly chosen logs for each fungi species. We placed the cores aseptically onto Hagem agar Petri dishes and identified any outgrowing mycelia from hyphal characteristics and back-paired to the original isolates (Holmer et al, 1997). The inoculations were successful: hyphae of the originally inoculated species were present in 54 and 46% of the logs for F. pinicola and R. bicolor, respectively.…”

Phellinus nigrolimitatus—a wood-decomposing fungus highly influenced by forestry

“…Thus, when it occurs in early decay classes, it may be a result of accidental absence of superior competitors. Holmer et al (1997) have demonstrated, however, that late succession species generally are superior competitors compared to early succession species. Unfortunately, no data exist on the competitive ability of P. nigrolimitatus, but if it follows the general pattern demonstrated by Holmer et al, this would imply that the typical absence on early decay classes is linked to factors other than competition.…”
