How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Purpose Measuring continuous root growth with less time- and resource-intensive methods is challenging for plant ecologists. We propose an approach where photos of fine root growth were taken with smartphones and analyzed by the deep learning method-based program RootPainter. Methods Picea abies saplings were grown in transparent boxes in growth c...
Global climate change scenarios predict an increase in air temperature, precipitation, and air humidity for northern latitudes. Elevated air humidity may significantly reduce the water flux through forest canopies and affect interactions between water and nutrient uptake. However, we have limited understanding of how altered transpiration would aff...
Global climate change scenarios predict increasing air temperature, enhanced precipitation and relative air humidity, mainly for Northern latitudes. We investigated the effects of elevated air relative humidity and different inorganic nitrogen sources (NO3-, NH4+) on above- and belowground traits in different tree species, with particular emphasize...
A growing body of evidence suggests that water uptake of plants depends on available N forms. The objective of this study was to investigate tree water flux at different levels of relative humidity (RH) of air, soil N source (ammonium, nitrate), and N contents. Aspen saplings demonstrated lower (p<0.05) night-time and daytime sap flux densities (F)...
Rising atmospheric temperature, precipitation and therefore the increase of air humidity will have a significant influence in plants’ growth and functioning in the near future. In the unique Free Air Humidity Manipulation experiment in Estonia, silver birch (Betula pendula Roth.) trees have shown to have a clear effect growing in elevated air humid...
Recent studies suggest that water and nitrogen uptake might be tightly interrelated processes. It has remained to be unclear whether and to what extent the interaction between water and nitrogen uptake is related to active membrane transport and how it depends on plant preference for inorganic nitrogen forms - nitrate and ammonium. This study aims...
The predicted increase of precipitation and therefore also air humidity (RH) in northen latitudes would have an influence on trees’ growth and functioning. Retardation of tree growth was found under elevated RH at free air humidity manipulation (FAHM) experiment. Air humidy can affect trees growth mainly through reduced transpiration: either direct...
The predicted increase of atmospheric temperatures, precipitation and therefore also air humidity in northern latitudes will have a significant influence in plants’ growth and functioning. Accessing different primary data is most valuable to put up modes for future to increase forests’ management manners and contribution to carbon sinks. There has...
