Understanding the ultimate causes of population declines and
extinction is vital in our quest to stop the currently rampant
biodiversity loss. Comparison of ecological characteristics between
threatened and nonthreatened species may reveal these ultimate
causes. Here, we report an analysis of ecological characteristics of
23 threatened and 72 nonthreatened butterfly species. Our analysis reveals that threatened butterflies are characterized by narrow
niche breadth, restricted resource distribution, poor dispersal ability, and short flight period. Based on the characteristics, we
constructed an ecological extinction risk rank and predicted which
of the currently nonthreatened species are at the highest risk of
extinction. Our analysis reveals that two species currently classified
as nonthreatened are, in fact, at high risk of extinction, and that the
status of a further five species should be reconsidered.

Verifying the predicted risk of extinction based on ecological characteristics
Komonen, Atte; Kotiaho, Janne S. (John Wiley & Sons, 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 ... -
Semi-natural habitats in the European boreal region : Caught in the socio-ecological extinction vortex?
Herzon, Irina; Raatikainen, Kaisa J.; Helm, Aveliina; Rūsiņa, Solvita; Wehn, Sølvi; Eriksson, Ove (Springer Science and Business Media LLC, 2022)We propose to consider semi-natural habitats—hotspots for biodiversity—being caught in a socio-ecological extinction vortex, similar to the phenomenon described for species threatened with extinction. These habitats are ... -
Lakeshore areas of conservation interest : Characteristics of nursery areas of the threatened lake‐dwelling grayling, Thymallus thymallus
Lehtonen, Topi K.; Hirvonen, Esa; Kolari, Irma; Ropponen, Janne; Nyholm, Kristiina; Keskinen, Tapio; Vehanen, Teppo (John Wiley & Sons, 2024)Research-based knowledge is essential for effective conservation and restoration of threatened aquatic species and habitats. Here, our aim was to gather this knowledge on the lake-dwelling grayling (Thymallus thymallus), ... -
Polypore communities and their substrate characteristics in Atlantic forest fragments in southeast Brazil
Komonen, Atte; Kokkonen, Miia; Araujo, Lucimar S.; Halme, Panu; Lopes-Andrade, Cristiano (Mongabay.com, 2018)Anthropogenic environmental changes have resulted in biodiversity crisis. Although tropical rainforests are one of the global biodiversity hotspots, their biodiversity is still poorly known. Especially fungi are poorly ... -
