“…Species were also classified regarding their functional association as xylophagous (eating dying or newly dead wood, also including ambrosia eaters), saproxylophagous (eating decayed wood), detrivores (eating dead insects, frass, etc. ), predators, or fungivores (eating fungi tissue) (Bouget et al 2005). Species information was collected from Palm (1951Palm ( , 1959, Koch (1989aKoch ( , 1989bKoch ( , 1992, Ehnström (2002, and personal communication) and Bouget (2005).…”

For conservation of forest biodiversity, dead wood in the form of logs, snags, or cut high stumps is sometimes left or created when forests are harvested. In Scandinavia, such dead wood usually comes from conifers. For forests in temperate regions, few studies have analysed composition and species richness of beetles using dead wood of oaks ( Quercus spp). In this study in southern Sweden, I examined the occurrence of saproxylic beetles trapped at lying (logs) and standing (snags) dead wood of European oaks ( Quercus robur L. and Quercus petraea (Mattuschka) Liebl.) in 13 oak-rich mixed forests of relatively high conservation value. The assemblage of beetles differed strikingly between the lying and standing dead wood. Traps on lying dead wood, compared to traps on standing dead wood, had more fungivores and fewer primary and secondary wood boring species. Of 94 species tested for individual substrate preferences, 48 showed prevalence for different trap/substrate types. Absolute species richness was significantly higher on logs than snags, but a smaller proportion of the snag substrate or snag beetles may have been sampled. For red-listed beetles, no differences in their species richness were detected among substrates. These results suggest that logs of dead oaks are valuable and that both snags and logs of oak should be retained and, if needed, created in forestry, such that they are continuously available in stands.

“…First, I have separated "obligate saproxylic" from "not saproxylic" species. Among saproxylic species, I have distinguished ecological guilds on the basis of feeding habits (see Bouget et al 2005 for details): "wastefeeders" use dead bodies or dung in galleries or in deadwood, "saproxylophagous" feed on a mixture of rotten wood with fungi, "fungivorous" feed on sporophores or myceliums, "xylophagous" concerns all the woody tissues in living or deadwood without any fungal presence, and "predator" attacks living animals.…”

Saproxylic beetle biodiversity in old‐growth forests of the south‐east of France

This study compared the richness of saproxylic beetle species and the composition of species assemblages between the major forests types of the south-east of France. The forests differed by their geographical position and their composition in tree species. The results confirmed the existence of a clear local identity of the saproxylic beetles communities. This identity combined three geographical and ecological factors: the geographical position, the altitude and the dominant species of trees. Surprisingly, the period length since the last important perturbation of the stand was not a determinant factor to explain the composition of the saproxylic communities. Selective logging and deadwood retention favoured the increase of the diversity of saproxylic species. This diversity reached a maximum during the first 10 years following the perturbation, was the lowest 30 years after the stand perturbation, but increased again after 50 years with a different species composition.

“…Fungi that focus on both Ascomycota and Basidiomycota, and beetles that focus strictly on saproxylic taxa (Bouget et al 2005), supplemented with beetles intensively reared on fungal fruiting bodies collected in the field in the study plots, were surveyed according to sampling methods used for similar studies in Europe for fungi (Bader et al 1995;Siitonen 2001) and beetles (Økland 1996;Martikainen & Kaila 2004;Wikars et al 2005). Fungal and beetle samplings were conducted at all the sites in 2008.…”

“…The latter begin to develop as soon as wood becomes dysfunctional, with colonization starting latently within the wood and decomposition when the host tree is dead. As regards the trophic roles of saproxylic beetles, the following were distinguished on the basis of feeding habits (Bouget et al 2005;Dodelin 2010): "waste-feeders" (WF), which feed on dead bodies or dung in galleries or in dead wood; "saproxylophagous" (SA), which feed on a mixture of rotten wood with fungi; "fungivorous" (FU), which feed on fruit-bodies or mycelia; "xylophagous" (XY), which feed on all the woody tissues in living or dead wood without any fungal presence; and "predators" (PR), which attack living insects of the preceding four categories (mostly larvae).…”

The fundamental ecological significance of deadwood decomposition in forests has been highlighted in several reviews, some conclusions regarding silviculture being drawn. Old-growth forests are natural centres of biodiversity. Saproxylic fungi and beetles, which are vital components of these ecosystems, occupy a variety of spatial and trophic niches. Fungal and beetle diversity on coarse woody debris (CWD) was analysed in 36 forest sites in the Cilento and Vallo di Diano National Park, Italy. The data were analysed by DCA and Spearman's rank correlation. The results provide empirical evidence of the existence of a pattern of joint colonization of the woody substrate by fungi and beetles, which includes an assemblage of reciprocal trophic roles within fungal/beetle communities. These organisms act together to form a dynamic taxonomical and functional ecosystem component within the complex set of processes involved in wood decay. The variables most predictive of correlations between management-related structural attributes and fungal/beetle species richness and their trophic roles for old-growth forest are: number of logs, number of decay classes and CWD total volume. Deadwood spatiotemporal continuity should be the main objective of forest planning to stop the loss of saproxylic fungal and insect biodiversity.
