Insights into the evolution of the young Lake Ohrid ecosystem and vegetation succession from a southern European refugium during the Early Pleistocene (2019)
Journal Article

© 2019 Mediterranean mid-altitude sites are critical for the survival of plant species allowing for elevational vegetation shifts in response to high-amplitude climate variability. Pollen records from the southern Balkans have underlined the importan...

Cover crops affect the partial nitrogen balance in a maize-forage cropping system (2019)
Journal Article

Part of the nitrogen (N) fertilizer applied to crops is lost to the environment, contributing to global warming, eutrophication, and groundwater contamination. However, low N supply stimulates soil organic N turnover and carbon (C) loss, since the so... Read More about Cover crops affect the partial nitrogen balance in a maize-forage cropping system.

Developmental roles of AUX1/LAX auxin influx carriers in plants (2019)
Journal Article

Plant hormone auxin regulates several aspects of plant growth and development. Auxin is predominantly synthesized in the shoot apex and developing leaf primordia and from there it is transported to the target tissues e.g. roots. Auxin transport is po...
