Local adaptation in island populations of Plectritis congesta that differ in historic exposure to ungulate browsers

Spatial variation in the occurrence of browsing ungulates can drive local adaptation in plant traits but also lead to trade‐offs among traits potentially enhancing competitive ability versus resistance or tolerance to browsing. Plectritis congesta populations co‐occurring on islands with and without ungulates offer striking examples of population‐level variation in traits, such as plant height and fruit morphology, which may also affect fitness....
