Species specific and environment induced variation of δ13C and δ15N in alpine plants
Frontiers in Plant Science, 2015 Stable carbon and nitrogen isotope signals in plant tissues integrate plant-environment interactions over long periods. In this study, we hypothesized that humid alpine life conditions are narrowing the scope for significant deviations from common carbon,

Permafrost and Periglacial Processes, Volume 36, Issue 4, Page 787-802, October/December 2025.ABSTRACT Rising sea levels and changing marine dynamics are increasing the inundation of previously terrestrial permafrost, accelerating thaw and altering microbial carbon cycling. On the Arctic Coastal Plain of Alaska, permafrost features like drained lake basins (DLBs) and uplands (ULs), offer distinct redox conditions and formation histories that ...

The Linnaean revolution – A history of the Natural System
TAXON, Volume 74, Issue 5, Page 1011-1034, October 2025.Abstract A very brief history of the Natural System (NS) is presented, focusing on angiosperms. The account is divided into four parts. The first, “Setting the stage”, gives an outline of my understanding of evolutionary ontology and how this reflects on taxonomy.
