Biogeographical determinants for total and endemic species richness in a continental archipelago

摘要: We examined the relationship between plant species richness and biogeographical variables (island area, island maximum elevation, distance from nearest inhabited island, mainland) using a data set comprising 201 islands of Aegean archipelago. found that endemic was strongly correlated to total richness. Single-island most then with an apparent small effect for smaller than 47 km2. Total area (with no effect), less elevation. Distance mainland or other displayed limited predictive value in our set. The slope geographical factors island/mainland) steeper Finally, different scales endemicity (single-island endemics, group endemics regional endemics) similar qualitative trends only differed quantitatively. Thus, we conclude act as drivers
