A resurrection study reveals limited evolution of phenology in response to recent climate change across the geographic range of the scarlet monkeyflower
Abstract Premise of the study As global climate change alters drought regimes, rapid evolution of traits that facilitate adaptation to drought can rescue populations in decline. The evolution of phenological advancement can allow plant populations to escape drought, but evolutionary responses in phe...
