| Περίληψη: | Biological invasions are a significant environmental concern with dire economic consequences. Understanding the ecological mechanisms behind biological invasions remains a focus of conservation biology. Several hypotheses highlight distinct environmental characteristics as the primary factors affecting the establishment and spread of alien species. Here, we approached these hypotheses by examining the spatio-temporal relationship between alien bird species richness and the biotic and abiotic characteristics of three US states (New York, Pennsylvania and Massachusetts), each state has been surveyed for two time periods (twenty years apart). We calculated native species richness and functional and phylogenetic diversity metrics. Using climate and land cover datasets, we extracted mean temperature, precipitation and land cover types, richness and diversity for each atlas cell for the different time periods. We used GLS models to account for spatial autocorrelation. We generated one model using the taxonomic, functional and phylogenetic metrics as predictors, one using the climatic metrics as predictors and one using land cover metrics as predictors for alien species richness. We found that the biotic characteristics were more strongly correlated with alien species richness, whereas climate and land cover characteristics exhibited a considerably weaker correlation with alien species richness. Our results show that alien species richness is consistently higher in areas with high native species diversity (taxonomic, functional and phylogenetic). Climate and land cover characteristics’ weak correlations with alien species richness indicate that the abiotic characteristics play a less important role than previously assumed. |
