Abstract Understanding spatial variation of species composition at different scales is essential for efficient conservation planning. Here, we investigate ecological uniqueness patterns freshwater macrophyte assemblages continental extents. We explored the similarities and differences in between Europe North America relation to richness environmental variables using presence–absence data 50 × km grid cells. To describe assemblages, used an index called ‘local contribution beta diversity’ (LCBD). First, linear regression evaluate relationship richness. Second, was modelled generalized additive modelling (GAM). Third, boosted tree (BRT) analysis performed with same compare BRT results from GAM. The revealed relatively similar both continents. overall negative but showed form degree America. main driver continents mean annual temperature, further effects associated precipitation, elevation range, alkalinity proportion freshwaters a cell. Synthesis . Our that may be negatively correlated large extents, likely depend on profile area. significant influence climate suggests changes land use shape unique assemblages. Thus, strategies should consider protection measures, especially northern areas as they are expected face many future. Identifying high important implementation biodiversity practices.
