Sažetak
Due to the spread of invasive alien species (IAS), European (including Croatian) landscapes are changing, while certain mechanisms that promote realization of invasive potential, are still unknown. Plant traits underpin species’ tolerance to environmental stressors and disturbances as well as their contributions to ecosystem properties, so they can provide insights in functional diversity analyzes between invaded and (yet) not invaded areas. With this ambition, we set out to review publicly available data on plant traits for 77 invasive plant species in Croatia. In this research we focused on numerical plant trait variables that describe persistence, regeneration and dispersibility – key features of plant dynamics, by investigating one whole plant trait (canopy height), four leaf traits (leaf size and mass, SLA, LDMC) and nine seed traits (seed length, width, height, number, number per shoot and longevity, releasing height, buoyancy and terminal velocity). Firstly, we examined LEDA Traitbase – an open Europe-wide database that gathers several sources of knowledge, and identified 4 species (5.2 %) represented with all 14 examined traits, 19 species (24.7%) represented with 11 or more traits and 22 species (28, 6 %) represented with no traits. Measurements for canopy height, seed length and releasing height were contained for more than 50% of species with seed length being the most common. Least amount of information (measured for less than 30% of species) was available for seed buoyancy and terminal velocity, with buoyancy being represented for only 8 species. Our plan is to expand the search for 14 selected plant traits by collecting data from the TRY Plant Trait Database, after which we will be able to identify Croatian plant IAS whose traits are not available and have to be measured by ourselves, in order to complete the data set needed for further analyses (e.g. functional diversity). Authors will carry out all the tasks, gathering the information on previously available traits until vegetation season of 2022, when the measuring of missing traits is planned to begin.
