Sažetak
The study reveals the connection between landscape structure and the composition of CSR types of invasive plants in different biogeographical regions in Croatia. Records on the localities of 57 invasive plants in three biogeographical regions (Alpine, Continental and Mediterranean) were used to analyse the occurrence of different CSR types with respect to the level of habitat heterogeneity in the regions. Data on the CSR types was available for the majority of species, whereas CSR types of 15 taxa were designated in this study. A total of 10 CSR functional types were found among the invasive flora of Croatia. The majority of invaders were CR-strategists, followed by C-strategists and R-strategists. The proportion of species exhibiting the CR strategy was highest in the Continental region, and the proportion of C-strategists was highest in the Alpine region. The Mediterranean region had the highest proportion of R-strategists (altogether a C-, CR- and R- gradient was visible across the regions). Additionally, the resulting values of landscape metrics revealed a landscape heterogeneity gradient between the regions, with the Mediterranean being the most and the Alpine the least heterogeneous region. Our results show that the proportions of CSR types reflect the amount of habitat heterogeneity at the landscape level (i.e., biogeographical regions), which is probably related to the intensity of human impact and associated disturbances.
