“…For invertebrates as well as vertebrates (Lawrence 1989;Johnson 1996) fungi display an important source for nutrition as they concentrate valuable nutrients about 10 times higher than the wood they grow on (Martin 1979;Jonsell and Nordlander 2004). It was suggested for a long time that host aroma compounds might play an important role during the colonization of fruiting bodies (Lawrence 1973;Nordlander 1995, 2004), but investigations of such interactions were sparse.…”

Fungi of the genus Trametes are known as important wood decomposers and are colonized by various species of Coleoptera and other arthropods. The aim of the present study was to investigate the importance of volatile chemical compounds as key attraction factors in recognition and host selection by species of Erotylidae (Dacne bipustulata, Tritoma bipustulata) as well as Cisidae (Sulcacis affinis) and Tenebrionidae (Diaperis boleti). Volatiles from freshly collected Trametes versicolor were collected by headspace sampling technique and identified by combined gas chromatography-mass spectrometry (GC-MS). To evaluate the biological significance of the volatiles we performed behavioural tests and recorded antennal responses of the fungus-inhabiting species by gas chromatography with electroantennographic detection (GC-EAD). The scent of T. versicolor was found to be dominated by sesquiterpenes; in GC-EAD 6 of these compounds elicited reproducible antennal signals in the tested species. Highly significant attraction effects to the fungus, the obtained odour samples and previously described fungal C 8 -compounds were observed in behavioural tests. The possibility to detect these chemical compounds as a key cue for host selection implicate that beetles are able to discriminate between fungi of different age as well as different stages of colonization.

“…Numerous insects live in close association with fungi, illustrated for example by F. fomentarius. Comparative studies revealed this typical beech forest fungus as one of the most insect species-rich fungi concerning Lepidoptera and Coleoptera (Jonsell and Nordlander 2004). If this fungus (see Table 4), once the most common in natural beech forests (Schmid and Helfer 1999), is reduced significantly, then many dependent species lose an essential habitat resource.…”

Assemblages of wood-inhabiting fungi related to silvicultural management intensity in beech forests in southern Germany

Current silvicultural treatments in beech forests are aimed at achieving thick logs without discoloured hardwood. Therefore intensive thinning is applied already in younger stands with the objective of large-sized trunks at an age of 100 years. However, this approach bears the risk that dead wood structures and broken trees are completely removed from the forest. The impact of three different silvicultural management intensity levels on wood-inhabiting fungi over decades was investigated in a large beech forest (>10,000 ha) in southern Germany in 69 sampling plots: A Intensive Thinning and Logging with high-value trees, B Conservation-Oriented Logging with integration of special structures such as dead wood and broken trees and C Strict Forest Reserves with no logging for 30 years. The analysis of community showed marked differences in the fungus species composition of the three treatments, independent of stand age. The relative frequencies of species between treatments were statistically different. Indicator species for naturalness were more abundant at sites with low silvicultural management intensity. Fomes fomentarius, the most common fungus in virgin forests and strict forest reserves, is almost missing in forests with highmanagement intensity. The species richness seemed to be lower where intensive thinning was applied (P = 0.051). Species characteristic for coarse woody debris were associated to low management intensity, whereas species with a significant preference for stumps became more frequent with increasing management intensity. A total amount of dead wood higher than 60 m 3 /ha was found to enable significantly higher numbers of species indicators of naturalness (P = 0.013). In conclusion, when applying intensive silvicultural treatment, the role of dead wood needs to be actively considered in order to maintain the natural biocoenosis of beech forests.

“…Durable, perennial fruit bodies support a larger proportion of associated monophagous insects than what are found in more short-lasting basidiocarp types. Perennial fungi provide a continuously available resource for Coleoptera, as Jonsell & Nordlander (2004) show with four perennial species (Fomes fomentarius, Fomitopsis pinicola, Ganoderma lipsiense, and Phellinus igniarius) vs. annual sturdy (Inonotus radiatus) and hibernating (Piptoporus betulinus) polypores. Komonen (2003) provided data on beetles of two red-listed polypores in Finland: perennial Fomitopsis rosea and annual ephemeral Amylocystis lapponica.…”

The paper summarizes fi eld inventories of polypores and associated beetles in northwestern Finland (Lapland) in the years [2001][2002][2003][2004]. The research area includes nearvirgin or old-growth forests of the Pallas-Yllästunturi National Park and the Pisavaara Strict Nature Reserve, one of the largest areas of protected forests in the country. Altogether 132 polypore species were found or (a few) documented from herbarium collections. Special attention was paid to those beetles that visit or inhabit polypores, either to consume their spores and mycelium, or living in polypore basidiocarps at larval stages. Beetle species compositions and their occurrences as larvae versus imagines differed according to the characteristics of polypore basidiomata. Four kinds (life cycles) of basidiomata were separated: ephemeral, annual sturdy, annual hibernating, and perennial. The selective effect of these life cycles over attracted beetles is extensively discussed with numerous examples. Parallels were found between the insects living in decayed wood versus mushrooms: while beetles of the ephemeral polypore hosts follow in their biology the "mushroom" pathway (pupating in soil debris), those living in perennial basidiocarps follow the "wood" pathway in both consuming the fungus and in pupating inside the decaying basidiocarp. The paper includes complete lists of polypores and polypore-linked beetles found in the study area. A number of wood-inhabiting fungi of other groups are listed, including observations of their beetle fauna. Also more theoretical aspects of the fungus-beetle interaction are discussed.
