Wood-inhabiting fungal responses to forest naturalness vary among morpho-groups
2021
The general negative impact of forestry on wood-inhabiting fungal diversity is well recognized, yet the effect of forest naturalness is poorly disentangled among different fungal groups inhabiting dead wood of different tree species. We studied the relationship between forest naturalness, log characteristics and diversity of different fungal morpho-groups inhabiting large decaying logs of similar quality in spruce dominated boreal forests. We sampled all non-lichenized fruitbodies from birch, spruce, pine and aspen in 12 semi-natural forest sites of varying level of naturalness. The overall fungal community composition was mostly determined by host tree species. However, when assessing the …
Stable carbon isotopic composition of peat columns, subsoil and vegetation on natural and forestry-drained boreal peatlands.
2018
We studied natural and forestry-drained peatlands to examine the effect of over 34 years lowered water table on the δ13C values of vegetation, bulk peat and subsoil. In the seven studied sites, δ13C in the basal peat layer was 1.1 and 1.2 ‰ lower than that of the middle-layer and surface layer, respectively. Furthermore, there was a positive correlation between the δ13C values of the basal and surface peat layers, possibly due to carbon (C) recycling within the peat column. In the same mire complex, natural fen peat δ13C values were lower than those of the nearby bog, possibly due to the dominance of vascular plants on fen and the generally larger share of recycled C in the fens than in the…

Elävät kuolleet : Aristoteles, Hobbes ja Fromm modernin zombikuvaston valossa
2019
Zombeja käsittelevät televisiosarjat ja sarjakuvat ovat viime vuosina saavuttaneet suurta suosiota. Esimerkiksi The Walking Dead -sarjan ensimmäinen jakso näytettiin samanaikaisesti 120 maassa, ja sarjaa on sittemmin katsonut tuotantokaudesta riippuen 5–15 miljoonaa katsojaa. Post-apokalyptinen maailma kiehtoo suurta yleisöä, koska dystooppiset tarinat peilaavat erilaisia käsityksiä ihmisten perusolemuksesta ja yhteiskunnan perustasta; sarjaa voi pitää filosofisena ajatuskokeena, jolla testataan, miten erilaiset näkemykset toimisivat luonnontilaan paluun jälkeen. Artikkelimme lähtökohta on, että zombikuvasto tarjoaa hedelmällisen tilaisuuden filosofiselle analyysille. Tarkastelemme yhteisku…
