Biotic threats for 23 major non-native tree species in Europe
(Peer reviewed; Journal article, 2021-08-06)For non-native tree species with an origin outside of Europe a detailed compilation of enemy species including the severity of their attack is lacking up to now. We collected information on native and non-native species ... -
Infection biology as the basis of integrated control of apple canker (Neonectria ditissima) in Northern Europe
(Peer reviewed; Journal article, 2021-01-25)Background: European canker, caused by Neonectria ditissima, is a disease of worldwide importance in apple production, yet knowledge about it is limited, highly regional and sometimes contradictory. This is an obstacle to ... -
Bioactive peptides from microalgae: Focus on anti-cancer and immunomodulating activity
(Peer reviewed; Journal article, 2021-06-03)In addition to the rapidly expanding field of using microalgae for food and feed, microalgae represent a tremendous potential for new bioactive compounds with health-promoting effects. One field where new therapeutics is ... -
