Resource use of wood-inhabiting fungi in different boreal forest types
2017
Generalist species are usually widespread and abundant, and thrive in heterogeneous environments. Specialists, in turn, are generally more restricted in their range, and benefit from more stable conditions. Therefore, increasing human-induced disturbance can have more negative effects on specialist than generalist species. We assessed the specialization of 77 wood-inhabiting fungal species across seven boreal forest types and different substratum qualities. A significantly higher number of specialist species was associated with herb-rich forests and afforested fields than with managed coniferous forests and wood pastures, the number of specialists associated with natural coniferous forests …
The role of novel forest ecosystems in the conservation of wood-inhabiting fungi in boreal broadleaved forests
2016
The increasing human impact on the earth’s biosphere is inflicting changes at all spatial scales. As well as deterioration and fragmentation of natural biological systems, these changes also led to other, unprecedented effects and emergence of novel habitats. In boreal zone, intensive forest management has negatively impacted a multitude of deadwood-associated species. This is especially alarming given the important role wood-inhabiting fungi have in the natural decay processes. In the boreal zone, natural broad-leaved-dominated, herb-rich forests are threatened habitats which have high wood-inhabiting fungal species richness. Fungal diversity in other broadleaved forest habitat types is po…
Updates to Finnish aphyllophoroid funga (Basidiomycota):new species and range extensions
2018
Abstract The knowledge of Finnish aphyllophoroid funga has increased substantially in recent years. In this article we present six species new to Finland: Cristinia (cf.) rhenana Grosse-Brauckm., Hyphodontiella hauerslevii K.H. Larss. & Hjortstam, Leptosporomyces montanus (Jülich) Ginns & M.N.L Lefebvre, Osteina obducta (Berk.) Donk, Sebacina helvelloides (Schwein.) Burt, and Tulasnella brinkmannii sensu lato Bres. The finding of Osteina obducta is the first record in Northern Europe. The article also contributes new records of 56 nationally rare species (maximum ten previous records in Finland). Additionally, we list 110 regionally new species, found for the first time from a certa…

Ecology, environmental requirements and conservation of corticioid fungi occupying small diameter dead wood
2016
The increasing human impact upon the biosphere of earth is causing profound changes across all spatial scales. The ability to cope with human-induced disturbance varies among organisms; specialist species are more negatively affected than generalist species. Forests are among the most heavily affected ecosystems; especially the dead wood associated organisms are in peril. The earlier research has strongly focused on large diameter dead wood and associated species. The aim of this thesis was to investigate small diameter dead wood and collect systematic information about species richness and abundance as well as habitat and substrate preferences of associated corticioid fungi. Fungal data wa…
