Description
Summary:Funding Information: First author acknowledges the mobility grant from Kempe Foundation (Kempestiftelserna) for funding the project “Fingerprinting of Microbial Communities on Contaminated Wooden Surfaces for Further Identification and Differentiation of Fungal Species and Strains” at Lulea University of Technology in Skellefteå, Sweden. Part of this work was conducted during the project WoodLCC, which is supported under the umbrella of ERA-NET Cofund ForestValue by the Ministry of Education, Science and Sport (MIZS) – Slovenia. The authors gratefully acknowledge the European Commission for funding the InnoRenew project (Grant Agreement #739574) under the Horizon2020 Widespread-Teaming program, the Republic of Slovenia (investment funding from the Republic of Slovenia and the European Union's European Regional Development Fund). This research was co-funded by the European Union (ERC, ARCHI-SKIN, #101044468). Views and opinions expressed are however those of the author(s) only and do not necessarily reflect those of the European Union or the European Research Council. Neither the European Union nor the granting authority can be held responsible for them. Natural weathering test at two different European climatic zones were conducted to investigate simultaneously both, the fungal colonisation and weathering process of Scots pine wood (Pinus sylvestris L.). The hypothesis was that the wood performing differently in various climate conditions might affect fungal infestation. The colour changes, wettability, and glossiness were measured as indicators of weathering progress of wood together with an assessment of fungal diversity. Different intensities in weathering, occupancy, and colonisation of fungi on wooden surface were detected. A higher number of fungal species was found on wood exposed to the warm temperate climates compared to subarctic or boreal climates. The dominant fungal species in both locations were from the genera Cladosporium and Aureobasidium. Peer reviewed
