State of forest research in 2010s – a bibliographic study with special reference to Finland, Sweden and Austria
Using bibliometric methods, this report analysed the volumes of global forest research and research collaboration between researchers, institutes and countries during the period 2010–2019. The keywords used in the bibliometric search resulted in a good match with the publication lists of three major Finnish forest research organisations. The final corpus of “forest” publications consisted of 355,000 articles, proceeding papers, reviews, books, book chapters and letters listed in the Web of Science database. During 2010–2019, the volume of Finnish publications in forest sciences have increased and the share of internationally collaborative papers has also grown. However, the international position of Finnish and Nordic forest research is slowly declining, owing to the modest growth in publishing, compared to fast-growing countries like China and Russia. When comparing Finnish and Swedish research organisations, those from Sweden were more internationally oriented. In both countries, the five top institutes produced more than three quarters of their country’s respective publications. Analyses based on bibliometric data used in this study reveal the status regarding publication output and trends. These analyses can provide objective evidence that is needed when developing research strategies and policies as well as allocating funding resources
Predicting the risk of extinction from shared ecological characteristics
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.peerReviewe
