“…This predominance of Coleoptera is reported to occur in northern Europe (Thunes et al, 2000;Komonen, 2001Komonen, , 2003a, North-east China (Komonen et al, 2003), the United Kingdom (Paviour-Smith, 1960) and Canada (Pielou & Verma, 1968). This pattern might be a general one for bracket fungi, irrespective of the longevity of the sporocarps (e.g.…”

Abstract.A study of the insect community inhabiting the wood-decaying bracket fungus, Cryptoporus volvatus was used to test two hypotheses proposed to account for the competitive coexistence of species in insect communities in patchy environments, niche partitioning and spatial mechanisms. A total of 8990 individuals belonging to 17 insect species emerged from 438 sporocarps (patches) collected from the field. Insect species richness increased and then declined with increase in the total insect biomass reared from a sporocarp, suggesting the potential importance of interspecific competition. Successional niche partitioning explained the spatial distribution of the four specialist species. The aggregation model of coexistence satisfactorily explained the stable coexistence of the species. The specialist species displayed higher population persistence than the generalists. Simulation studies suggest that restricted movements of adults could override patch-level larval aggregation. The effect of such restricted movements on stabilizing coexistence in fungus-insect communities has not been previously appreciated. These findings suggest that spatial mechanisms play a crucial role in the competitive coexistence of the species in the mycophagous insect communities inhabiting bracket fungi.

“…Diptera have a short larval period and dominate in the short lived agaric fungi (Kimura, 1976;Hackman & Meinander, 1979;Lacy, 1984;Yamashita & Hijii, 2003), and Coleoptera a long larval period and dominate long lived polypores (Aphyllophorales; Pielou & Verma, 1968;Hågvar, 1999, Jonsell et al, 2001. In mycophagous drosophilids, the longevity of their fungal host's fruiting body is similar to that of their larval period (Toda & Kimura, 1997).…”

Abstract. We hypothesize that differences in fungal taxonomic groups may exert a direct influence on the composition of mycophagous insect communities, and that the relative importance of taxonomy compared to other fungal traits may change as the mushrooms decay. We conducted a 3-year field survey and analyzed the species composition of mycophagous insect communities using partial canonical correspondence analysis (partial CCA). We collected 2457 mushrooms belonging to 27 genera, and 4616 insects belonging to 16 families emerged from 439 of the mushrooms. For the whole insect community, fungal genera explained 10-19% of the total variance in the family composition of the insect communities of mushrooms at different developmental stages. Only the fungal genus Collybia significantly affected the community composition almost irrespective of developmental stage. In the drosophilid community, which consisted of 844 individuals from 9 species, fungal genera explained 19-34% of the total variance. Some fungal genera, such as Amanita and Collybia, affected the drosophilid community, but not at all developmental stages. The number of fungal genera that significantly affected the insect community composition did not differ among fungal stages both in the whole insect community and in the drosophilid community. Thus, our former hypothesis was supported by the present analysis, whereas the latter was not. However, the percentages of variance explained by fungal genera were rather small. This suggests that the importance of fungal genera is likely to be less significant than that of other selection pressures in determining the species composition of mycophagous insect communities.

“…These mites crawl through rotting sludge, fi lter-feeding on bacteria, yeasts and very fi ne particulate organic matter (Walter and Kaplan 1990 ). In boreal to cool temperate forests, the acarofauna in long-lived bracket fungi is often dominated by oribatid mites (Pielou and Verma 1968 ;Matthewman and Pielou 1971 ;O'Connell and Bolger 1997 ). Annual and perennial bracket fungi have a much more diverse fauna of oribatid mites than that of the more ephemeral agaric and bolete fungi.…”

“…In temperate forests, the Mesostigmata assemblages on bracket fungi are composed of species in about a dozen genera (Pielou and Verma 1968 ;Matthewman and Pielou 1971 ;Lindquist 1975Lindquist , 1995OConnor 1984 ;O'Connell and Bolger 1997 ;Gwiazdowicz and Lakomy 2002 ). In more tropical realms, a diversity of unusual forms can be found (Moraza and Lindquist 2011 ).…”
