Light response of beech and fir in the Carpathian and Dinaric Mountains

Popis výsledku v původním jazyce

Global change mitigations based on environmental variables such as temperature and water availability lack the integration of current environmental responses. Physiological limits should be assessed to obtain a basic and updated representation of a species&apos; fundamental niche. Detailed ecophysiological studies on the light response of trees have been performed during three consecutive growing seasons along the latitudinal gradients of Dinarides and the Carpathians. In uneven-aged beech fir managed and old growth forests, all located above 800 m a.s.l., quantum yield () were measured for beech and fir in three predefined light intensity categories according to the indirect site factor (ISF%) obtained by the analysis of hemispherical photographs. The measurements were carried out under fixed environmental conditions and compared with the last 50-year average period from the CRU TS 4.01 dataset. The highest  for beech were observed in the central part of the Dinaric Mountains and in the southwesternmost and northwesternmost part of the Carpathians for both beech and fir, while they were highest for fir in the Dinarides in the northwesternmost part of the study area. The -value of beech decreased in both complexes with increasing mean annual temperature and was highest in the open landscape. For fir in the Carpathians,  decreased with increasing mean annual temperature, while in the Dinarides it increased with higher temperature and showed a more scattered response compared to the Carpathians. Ecophysiological responses of beech and fir were consistent to long-term radial growth observations observed on same locations. Results may serve as a basis for the future response of two tree species in terms of competitiveness, existence, and forest managementpraxis.
