Under global change, populations have four possible responses: ‘migrate, acclimate, adapt or die’ (Gienapp et al. 2008 Climate change and evolution: disentangling environmental and genetic response. Mol. Ecol. 17, 167–178. (doi:10.1111/j.1365-294X.2007.03413.x)). The challenge is to predict how much migration, acclimatization or adaptation populations are capable of. We have previously shown that populations from more variable environments are more plastic (Schaum et al. 2013 Variation in plastic responses of a globally distributed picoplankton species to ocean acidification. Nature 3, 298–230. (doi:10.1038/nclimate1774)), and here we use experimental evolution with a marine microbe to learn that plastic responses predict the extent of adaptation in the face of elevated partial pressure of CO2 (pCO2). Specifically, plastic populations evolve more, and plastic responses in traits other than growth can predict changes in growth in a marine microbe. The relationship between plasticity and evolution is strongest ... : Data for Figure 1Description: columns in csv file contain data as follows: ecotype - lineage of Ostreococccus. Initial plasticity - plasticity as measured at t0. Response - fitness response as measured at t400. for calculation see main manuscript and SI. whichresp - indicates whether response was measured in ancestral or selection environment. sdini and sdresp are standard deviations for plasticity at t0 and fitness response at t400 respectively. Here, they are pooled for 3 biological and 3 technical replicates. clade - clade A,B,C,D based on ITS sequences. year and culturing for year of isolation and culturing method at the Roscoff culture collection respectively. wherefrom: sampling depth as factor. Pst0 and growtht0 - are photosynthesis and growth rates at t0 (foldchange PS and foldchangegrowth are foldchanges thereof). Figure legend: (a–d) Lineages with higher ancestral plasticity evolve more. Direct and correlated responses to selection plotted as a function of plasticity in oxygen evolution rates ...
