“…In forest traps, 83% of all beetle species were caught before July (Burner et al, 2022), indicating that the flight period of most forest beetles is indeed early in the season. For fungus‐visiting beetles, this seasonal pattern could also be related to the spore production of F. pinicola , which is largest in spring (Norros et al, 2023; Nuss, 1986). True flies, slugs and centipedes exhibited seasonal variation as well, but appeared later in the season, indicating that they are less dependent of sporulation rates.…”

“…invertebrates seemed to correlate with the fungal sporulation period, that is, in spring and at night (Norros et al, 2023;Nuss, 1986), these visitors could potentially be dispersing the spores of F. pinicola.

“…Thus, understanding how invertebrates use this fungal resource may have large implications on the fungal community itself. Spore production, which varies throughout the day and season (Haard & Kramer, 1970;Norros et al, 2023;Nuss, 1986), competition and predation might determine the realised niches of invertebrates visiting fungal fruit bodies.…”

“…Many invertebrates, especially beetles, visit the fruit body surface at night in spring (Hågvar, 1999;Krasutskii, 2007), that is, when spore production is highest (Norros et al, 2023). A recent study showed how these beetles could serve as vectors for dispersing F. pinicola spores (Lunde et al, 2023), but more research is needed on their visitation patterns to understand the importance of this interaction.…”

“…The rove beetle Gyrophaena boleti is a specialist fungivore, developing inside individual pores of the F. pinicola fruit body as a larva, while the adults can be seen on the surface in large clusters during spring and early summer (Hågvar, 2018; Staniec et al, 2016). Many invertebrates, especially beetles, visit the fruit body surface at night in spring (Hågvar, 1999; Krasutskii, 2007), that is, when spore production is highest (Norros et al, 2023).

Fungi and invertebrates comprise a major part of biodiversity in dead wood ecosystems and invertebrates depend on fungi to utilise the dead wood resource. Many invertebrates also visit the long‐lived fruit bodies of wood‐decay fungi to feed on spores, the hymenium or other invertebrates. However, as traditional sampling methods are labour‐intensive, we know little of these interactions. In this study, we use time‐lapse cameras to monitor invertebrates visiting the hymenium of a common wood‐decay fungus, Fomitopsis pinicola, and explain their activity in terms of temporal variation, temperature and presence of Gyrophaena boleti, a highly abundant fungivorous beetle living primarily in fruit bodies of F. pinicola. The most common invertebrates on F. pinicola fruit bodies were Coleoptera, Araneae, Diptera, Gastropoda and Chilopoda. The invertebrate activity exhibited strong temporal variation with higher abundance during night and, for Coleoptera, earlier in the season. We discuss how this might correlate with the sporulation period of F. pinicola. The presence of G. boleti had a positive impact on the predatory Lordithon lunulatus and Ipidia binotata, and a negative impact on the fungivorous Thymalus limbatus and Peltis ferruginea. Chilopoda and L. lunulatus were ephemeral visitors, while the fungivorous Coleoptera and Araneae stayed the longest. We estimated the invertebrates' visitation frequency and duration, which would be time‐consuming to obtain with traditional methods. We offer improvements to our method and urge future research on invertebrate–fungus interactions to quantify invertebrate visits to fungal fruit bodies.

Exposure to the indoor airborne microbiome is closely related to the air that individuals breathe. However, the floor dust-borne microbiome is commonly used as a proxy for indoor airborne microbiome, and the spatial distribution of indoor airborne microbiome is less well understood. This study aimed to characterize indoor airborne microorganisms at varying heights and compare them with those in floor dust. An assembly of three horizontally and three vertically positioned Petri dishes coated with mineral oil was applied for passive air sampling continuously at three heights without interruption. The airborne microbiomes at the three different heights showed slight stratification and differed significantly from those found in the floor dust. Based on the apportionment results from the fast expectation−maximization algorithm (FEAST), shoe sole dust contributed approximately 4% to indoor airborne bacteria and 14% to airborne fungi, a contribution that is comparable to that from the floor dust-borne microbiome. The results indicated that floor dust may not be a reliable proxy for indoor airborne microbiome. Moreover, the study highlights the need for height-resolved studies of indoor airborne microbiomes among humans in different activity modes and life states. Additionally, shoe sole-dust-associated microorganisms could potentially be a source to "re-wild" the indoor microbiota.

Fungi are among the most diverse and ecologically important kingdoms in life. However, the distributional ranges of fungi remain largely unknown as do the ecological mechanisms that shape their distributions1,2. To provide an integrated view of the spatial and seasonal dynamics of fungi, we implemented a globally distributed standardized aerial sampling of fungal spores3. The vast majority of operational taxonomic units were detected within only one climatic zone, and the spatiotemporal patterns of species richness and community composition were mostly explained by annual mean air temperature. Tropical regions hosted the highest fungal diversity except for lichenized, ericoid mycorrhizal and ectomycorrhizal fungi, which reached their peak diversity in temperate regions. The sensitivity in climatic responses was associated with phylogenetic relatedness, suggesting that large-scale distributions of some fungal groups are partially constrained by their ancestral niche. There was a strong phylogenetic signal in seasonal sensitivity, suggesting that some groups of fungi have retained their ancestral trait of sporulating for only a short period. Overall, our results show that the hyperdiverse kingdom of fungi follows globally highly predictable spatial and temporal dynamics, with seasonality in both species richness and community composition increasing with latitude. Our study reports patterns resembling those described for other major groups of organisms, thus making a major contribution to the long-standing debate on whether organisms with a microbial lifestyle follow the global biodiversity paradigms known for macroorganisms4,5.
