Naturalization of garden plants as a result of interplay of species traits, propagule pressure and residence time

Name:	Naturalization of garden plants as a result of interplay of species traits, propagule pressure and residence time
Researchers:	Pergl Jan (researcher)
Provider:	Grantová agentura Akademie věd CR
Number:	GAP504/11/1028
Realization from:	2011
Realization to:	2015
Summary:	The proposed project will address, by using ornamental species, the effect of determinants of successful naturalization, i.e. what is the role of species biological traits, propagule pressure and residence time. The pool of species studies will include species that do not escape from cultivation, hence using information on failed introductions which is rarely considered in current studies. The project will be based on collated primary data (i) from floristic inventory of plants cultivated in gardens in the Czech Republic, which will provide measure of propagule pressure, and (ii) on species biological traits. This approach will allow to test whether invasions of garden plants are largely determined by species traits or stochastic factors. The project will evaluate existing weed risk assessment schemes for predicting probability of invasion by particular species, and test risks associated with cultivation of species that may become problematic in the future.
