Overlap in substrate utilisation and spatial exclusion in some microfungi which act as early cellulose colonisers in a Mediterranean environment

摘要: Abstract A trapping system was set up to isolate culturable cellulolytic fungi at the soil-leaf litter interface in an area of Mediterranean maquis located southern Italy. Seven taxa were isolated and cultured represent pioneers primordial phase cellulose colonisation. The functional diversity fungal isolates analysed using a phenotype microarray technique generate profile their traits. extent overlap substrate utilisation by various species subsequently determined. Some that acted as key decomposers are considered globally distributed air-borne contaminants. Most during experiment also well known for competitive abilities. Our study showed early stage colonisation few with potential overall metabolic function able establish themselves. prevailed onset did not co-occur field sites. sort “founder effect” could be hypothesised microfungi when colonising sterile cellulose. This would suggest scale (i.e. spatial component) exerts strong influence on causative mechanisms link genetic specific ecosystem functions.
