Institute, laboratory: Institute of Botany, Laboratory of Flora and Geobotany

Scientific Supervisor: dr. Zigmantas Gudžinskas

Study period: 2019-01-02 – 2022-12-31

Research theme: Comparative study on traits and ecological performance of alien and native Cornus species in the southern hemiboreal zone of Europe.

Short annotation (the aim, objectives)


• To evaluate and compare the biological traits of the Cornus sanguinea and C. alba and their subspecies, which determine the strategy of their distribution;

• To assess ecological characteristics of the study species and subspecies influencing occupation of the ecological niches and the role in communities;

• To investigate the spatial distribution and dynamics of species and subspecies according to the ecological gradient.
