Multivariate analysis of phyto-climatic patterns of the Croatian part of the eastern Adriatic coast

ABSTRACT

The present study analyses the climatic patterns of that part of the eastern Adriatic coast belonging to the Republic of Croatia and the narrow zone of the inlands. This area comprises a part of the Mediterranean phytogeographic region characterised by the Mediterranean climate type, and the transitional area towards the Eurosiberian phytogeographic region influenced by the continental climate type. The analysis was performed using multivariate numerical methods, cluster analysis following by the inertia analysis, and Principal Components Analysis with partitioning, considering the principal local climatic gradients in the data set. Six main climate classes were obtained. The results are biologically more interpretable than those obtained by using either numerical indices or the Walter climate diagram system. This suggests that multivariate numerical methods could be more efficient tools for detecting biologically significant climatic patterns on a small spatial scale.
