An island view of endemic rarity—Environmental drivers and consequences for nature conservation

Aim Rarity—an important measure for conservation biogeography—can vary over many orders of magnitude. However, it is unclear which regional‐scale abiotic conditions drive processes affecting rarity of endemic species on islands. To support conservation efforts, we (1) assess the main abiotic drivers of endemic rarity, (2) determine how well existing protected areas ( PA s) coincide with hotspots of endemic rarity and (3) introduce and evaluate a...
