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 …

Extinction risk indices for measuring and promoting planetary well-being

2024

The concept of planetary well-being, which stresses the persistence of lineages in ecosystems, is intimately linked to species extinction risk. Avoiding extinctions is a moral issue, as wiping out the outcomes of eons of evolutionary history and their future potential is clearly unconscionable. The concept of planetary well-being is also systemic: It is understood that species, as integral parts of ecosystems, are vital for the well-being of all systems on Earth. Yet, despite international agreements to protect biodiversity, global biodiversity loss and ecosystem degradation has continued unimpeded over the past decades. We review the role of goals and targets in the UN Convention on Biolog…

Wood-decaying fungi in old-growth boreal forest fragments: extinctions and colonizations over 20 years

2021

According to ecology theory, isolated habitat fragments cannot maintain populations of specialized species. Yet, empirical evidence based on monitoring of the same fragments over time is still limited. We studied the colonization–extinction dynamics of eight wood-decaying fungal species in 16 old-growth forest fragments (<14 ha) over a 20-year period (1997–2017). We observed 19 extinctions and 5 colonizations; yet, the distribution of extinctions and colonizations did not differ from the one expected by chance for any of the species. Twenty-six percent of the extinctions took place in two natural fragments amid large forest–peatland complexes. (Romell) Bourdot and Galzin decreased …

Being Itself and the Being of Beings : Reading Aristotle’s Critique of Parmenides (Physics 1.3) after Metaphysics

2018

The essay studies Aristotle’s critique of Parmenides (Physics 1.3) in the light of the Heideggerian account of Platonic-Aristotelian metaphysics as an approach to being (Sein) in terms of beings (das Seiende). Aristotle’s critique focuses on the presuppositions of the Parmenidean thesis of the unity of being. It is argued that a close study of the presuppositions of Aristotle’s own critique reveals an important difference between the Aristotelian metaphysical framework and the Parmenidean “protometaphysical” approach. The Parmenides fragments indicate being as such in the sense of the pure, undifferentiated “is there” (τὸ ἐόν)—as the intelligible accessibility of meaningful reality to think…

Hans-Georg Gadamerin (1900–2002), Jacques Derridan (1930–2004), Paul Ricœurin (1913–2005), Philippe Lacoue-Labarthen (1940–2007) ja Bernard Stieglerin (1952–2020) jälkeen Nancy oli viimeisiä suuria nimiä, jotka kannattelivat ja välittivät tiettyä filosofista ajatuskaarta. nonPeerReviewed

Verifying the predicted risk of extinction based on ecological characteristics

2021

Red List status of species should reflect species extinction risk. Because data are limited and species response has a time lag, species may be threatened by extinction even if they are not Red‐Listed. The ability to predict species risk of extinction from ecological characteristics holds promises for proactively targeting conservation measures to species at high risk. In 2005, the risk of extinction from ecological characteristics was predicted for 81 species of Finnish butterflies. Now, after 15 years and two additional national Red List assessments, these predictions are verified. Species with a higher risk of extinction according to the original ecological extinction risk rank (EERR) ha…
