title: Data from: Priority effects of early successional insects influence late successional fungi in dead wood

description: Community assembly is an integral process in all ecosystems, producing
 patterns of species distributions, biodiversity, and ecosystem
 functioning. Environmental filters and colonization history govern the
 assembly process, but their relative importance varies depending on the
 study system. Dead wood decomposition is a slow process, allowing
 decomposer communities to develop within a slowly changing substrate for
 decades. Despite this, there are few long-term studies of priority effects
 from colonization history in this ecosystem. In this study, we investigate
 the importance of insects in early succession of dead wood on the fungal
 community present one decade later. Sixty aspen trees were killed in two
 study landscapes, each tree producing one aspen high stump and log.
 Insects were sampled with flight interception traps during the first 4
 years after tree death, and fungal fruiting bodies were registered in year
 twelve. We found positive priority effects of two fungivorous beetles, the
 sap beetle Glischrochilus quadripunctatus and the round fungus beetle
 Agathidium nigripenne, on the Artist's bracket (Ganoderma applanatum)
 and a positive priority effect of wood-boring beetles on the ascomycete
 Yellow fairy cup (Bisporella citrina). The Aspen bracket (Phellinus
 tremulae) did not respond to insects in early succession of the dead wood.
 Our results suggest that early successional insects can have significant,
 long-lasting effects on the late successional fungal community in dead
 wood. Also, the effect can be specific, with one fungus species depending
 on one or a few fungivorous beetle species. This has implications for
 decomposition and biodiversity in dead wood, as loss of early colonizing
 beetles may also affect the successional pathways they seem to initiate.
description: GLM data for Jacobsen et
 al Priority effects of early successional insects influence late
 successional fungi in dead woodThe Fungi data sheet
 includes, divided by site, presence-absence data from 2013 for the species
 of fungi analysed in the article (G.applanatum13, P.tremulae13 and
 B.citrina13), presence-absence data for the fungi registered in 2005
 (S.paradoxa05, T.betulina05, C.unicolor05, T.hirsuta05, P.tremulae05),
 number of sampled individuals during 2002-2005 of wood-boring beetles with
 preference for deciduous wood in total (Wood-borers) and divided by family
 (wCerambycidae, wCurculionidae and wPtinidae), of fungivores with a
 preference for deciduous wood divided by family (fCiidae, fErotylidae,
 fEndomychidae, fLatridiidae, fLeiodidae, fPtinidae, fStaphylinidae and
 fNitidulidae), of the single species tested for the article (A.nigripenne,
 A.humeralis, G.quadripunctatus, G.hortensis) and average percent (0-1)
 remaining bark on the aspen high stump and log in 2005 (Site_bark).
 Additionally, site ID, x and y coordinates, habitat type (Open/Closed) and
 study landscape (Losby/LV) of each site is recorded. The Bark data sheet
 includes percent bark (0-1) remaining at each highstump and log at each
 site in 2005, presence-absence data of B.citrina in 2013 for each
 highstump and log at each site, dead wood object (snag=high stump/log),
 site ID, x and y coordinates, habitat type (Open/Closed) and study
 landscape (Losby/LV).
