that it does not already inhabit. It is very improbable that evolutionary responses would be sufficient to prevent species extinctions in the case of that species losing its climate space entirely on a regional or global scale  . At the highest risk are the world's most cold-adapted species . Examples include the polar bear , 'sky-island' plants in the Tropics , mountain-top amphibians in Spain , mountain-top lichens in the Appalachians   and silverswords in Hawaii . However, there is potential for using evolutionary changes to enhance the adaptive capacity of target species, as is being done on the Great Barrier Reef by translocating symbionts and corals that have survived recent intense heat-induced bleaching events into areas that have had large die-off . Multiple studies have assessed when and how evolution might be able to help wild species adapt to climate change .
