Bryophytes are a dominant vegetation component of the boreal forest, but little is known about their associated fungal communities, including seasonal variation within them.•Seasonal variation in the fungal biomass and composition of fungal communities associated with three widespread boreal bryophytes was investigated using HPLC assays of ergosterol and amplicon pyrosequencing of the internal transcribed spacer 2 (ITS2) region of rDNA.•The bryophyte phyllosphere community was dominated by Ascomycota. Fungal biomass did not decline appreciably in winter (P = 0.272). Significant host-specific patterns in seasonal variation of biomass were detected (P = 0.003). Although seasonal effects were not the primary factors structuring community composition, collection date significantly explained (P = 0.001) variation not attributed to locality, host, and tissue. Community homogenization and a reduction in turnover occurred with the onset of frost events and subzero air and soil temperatures. Fluctuations in the relative abundance of particular fungal groups seem to reflect the nature of their association with mosses, although conclusions are drawn with caution because of potential methodological bias.•The moss-associated fungal community is dynamic, exhibiting seasonal turnover in composition and relative abundance of different fungal groups, and significant fungal biomass is present year-round, suggesting a winter-active fungal community.

Abstract
Tourism is acknowledged to be an important business sector in rural areas. This paper argues that second-home owners constitute an important market segment for businesses that offer nature-based tourism activities. Previous research has shown that a number of factors influence tourist behaviour. This study examined how motivation and demographic variables affect second-home owners’ intention to purchase three different types of activity products: learning, adventure, and hunting products.We found substantial variations in the purchase intentions for these products among second-home owners. These intentions were influenced by push and pull motivations, age, income and educational level. Secondhome owners with a high intention of purchasing nature-based tourism activity products tend to be young, high-income, and socially oriented risk takers. Businesses offering nature-based tourism activity products should use a combination of demographic and psychographic variables when they segment the second-home market.
