How does the current climate change affect the phenology and physiology of selected Central European flood-plain forest tree species?

Floodplain forests are biodiversity-rich ecosystems found in many parts of Central Europe near watercourses and are part-time flooded during the course of the year. Floodplain forests are currently facing changes in environment related to climate change, for example increasing temperature and drought, elevated CO2 levels and excessive flooding. Woody plants respond to these changes by shifting the spring phenological phases, increasingly earlier onset of bud break occurs among different tree. Furthermore, there are various physiological, anatomical and morphological adaptations to these changes, through which plants try to avoid their damage. The plant response to changing environment is influenced by many endogenous factors, such as the degree of tolerance to flooding, the type of wood structure, position of a species on the isohydry-anisohydry scale or plant age, in addition to external factors, to which an extent of stress factor effect and its duration belong. In the future, a further increases in the average temperature, the CO2 concentration in the atmosphere and above-average flooding are expected, therefore it is important to understand the complex reactions and adaptations of floodplain forest trees to these changes in order to manage effectively these ecosystems.
