Do climatically similar regions contain similar alien floras? A comparison between the mediterranean areas of central Chile and California

Abstract

Aim Taxonomic comparisons of alien floras across climatically similar regions have been proposed as a powerful approach for increasing our understanding of plant invasions across scales. However, detailed comparisons between the alien biotas of climatically similar regions are scarce. This study aims to compare the taxonomic patterns of alien species richness in mediterranean-type climate areas of central Chile and California, in order to better understand how climatically similar regions converge or diverge in terms of their alien flora.
