Abstract：
Natural forests contain a large amount of deadwood, which is a key contributor to biodiversity,especially by providing dynamic habitats and resources for a huge variety of invertebrates. However, for managing forest biodiversity we need tobetter understand what drives the dynamics ofinvertebrate communities in deadwood. Wehypothesized that the invertebrate communities inlogs will converge from initial to middle decomposition stage among tree species and forest standsas the differentiating role of bark diminishes andxylem traits converge during decay. We investigated invertebrate communities in decomposinglogs of ten tree species over 4 years in the "treecemetery" LOGLIFE experiment in two contrasting forests in the Netherlands. The predominant faunalgroups studied were Annelida (earthworms), Isopoda (woodlice), Chilopoda (centipedes), Diplopoda (millipedes), Diptera (flies, midges) andColeoptera (beetles). We demonstrated that (1) treespecies, decay stages and incubation forests all hadeffects on the invertebrate communities; (2) community compositions of fauna in logs first werevery dissimilar and then became more similaramong tree species through the decay years; and(3) this converging pattern of faunal communitydynamics also manifested itself, both across andwithin given tree species, between two contrastingforests over decomposition time. Thus, invertebratecommunities generally converged during deadwood decay, which adds fundamental insights intothe role of interacting drivers of community succession. These findings also highlight that, bothwithin and among forests, more functionally different tree species and logs in different decaystages, will support relatively high biodiversity ofinvertebrate communities; these patterns may inform forest management strategies aimed at maximizing biodiversity.
