“…As a consequence, in fungi inhabiting dead wood, knowledge on ecological characteristics such as resource use is mainly based on data on fruit bodies (Jonsson et al, 2005;Junninen et al, 2006;Ó dor et al, 2006;Penttilä et al, 2006;Hottola et al, 2009;Gates et al, 2011).…”

Before the recent revolution in molecular biology, field studies on fungal communities were mostly confined to fruit bodies, whereas mycelial interactions were studied in the laboratory. Here we combine high-throughput sequencing with a fruit body inventory to study simultaneously mycelial and fruit body occurrences in a community of fungi inhabiting dead wood of Norway spruce. We studied mycelial occurrence by extracting DNA from wood samples followed by 454-sequencing of the ITS1 and ITS2 regions and an automated procedure for species identification. In total, we detected 198 species as mycelia and 137 species as fruit bodies. The correlation between mycelial and fruit body occurrences was high for the majority of the species, suggesting that highthroughput sequencing can successfully characterize the dominating fungal communities, despite possible biases related to sampling, PCR, sequencing and molecular identification. We used the fruit body and molecular data to test hypothesized links between life history and population dynamic parameters. We show that the species that have on average a high mycelial abundance also have a high fruiting rate and produce large fruit bodies, leading to a positive feedback loop in their population dynamics. Earlier studies have shown that species with specialized resource requirements are rarely seen fruiting, for which reason they are often classified as red-listed. We show with the help of high-throughput sequencing that some of these species are more abundant as mycelium in wood than what could be expected from their occurrence as fruit bodies.

“…Apart from its importance for biogeochemical cycling, dead wood in the forest is also a great source of biodiversity (Harmon et al 1986;Jonsson and Jonsson 2007;Wirth et al 2009). Northern forests in cool and cold biomes, for instance, support a wealth of wood-rot fungi (Odor et al 2006;Schmidt 2006;Hottola et al 2009), vertebrates (Bunnell and Houde 2010), diverse taxa of invertebrates (Grosser 1985;Grove 2002;Castro and Wise 2010;Dechene and Buddle 2010;Janssen et al 2011;Ulyshen et al 2011), lichens (Humphrey et al 2002) and bryophytes (Andersson and Hytteborn 1991;Humphrey et al 2002). Bacteria are among the first organisms to colonise dead wood and metabolise especially the easily degradable and accessible substrates (Schmidt 2006;De Boer and Van der Wal 2008).…”

Dead wood provides a huge terrestrial carbon stock and a habitat to wide-ranging organisms during its decay. Our brief review highlights that, in order to understand environmental change impacts on these functions, we need to quantify the contributions of different interacting biotic and abiotic drivers to wood decomposition. LOG-LIFE is a new long-term 'common-garden' experiment to disentangle the effects of species' wood traits and siterelated environmental drivers on wood decomposition dynamics and its associated diversity of microbial and invertebrate communities. This experiment is firmly rooted in pioneering experiments under the directorship of Terry Callaghan at Abisko Research Station, Sweden. LOGLIFE features two contrasting forest sites in the Netherlands, each hosting a similar set of coarse logs and branches of 10 tree species. LOGLIFE welcomes other researchers to test further questions concerning coarse wood decay that will also help to optimise forest management in view of carbon sequestration and biodiversity conservation.

“…A well-known example is the comparison of fungal species richness and community composition in natural and managed forests. The differences in fungal assemblages are mostly explained by the differences in the dead wood profile of the forests (Penttilä et al 2004, Hottola et al 2009, Abrego & Salcedo 2013. However, the dead wood profile does not seem to be the only determining factor explaining the differences in fungal communities among different forest types.…”

Resource use of wood-inhabiting fungi in different boreal forest types

Generalist species are usually widespread and abundant, and thrive in heterogeneous environments.Specialists, in turn, are generally more restricted in their range, and benefit from more stable conditions. Therefore, increasing human-induced disturbance can have more negative effects on specialist than generalist species. We assessed the specialization of 77 wood-inhabiting fungal species across seven boreal forest types and different substratum qualities. A significantly higher number of specialist species was associated with herb-rich forests and afforested fields than with managed coniferous forests and wood pastures, the number of specialists associated with natural coniferous forests being intermediate. Also, forest type specialists were indicated to be specialists for their substratum tree species as well, but specialization in substratum diameter was not connected with other kinds of specialization. Species with restricted resource or habitat preferences can less readily respond to environmental change, and therefore are more vulnerable to extinction.
