Data from: Artificial selection reveals high genetic variation in phenology at the trailing edge of a species range

This data file includes flowering time, specific leaf area, leaf nitrogen content, relative growth rate, and carbon isotope ratio for each Mimulus cardinalis individual in experiment (see publication for further details). Column names are as follows: Generation: year in which artificial selection was performed; parental generation (2012); 1 generation of selection (2013); 2 generations of selection (2014) Region: range position from which populations originate; northern edge (N), latitudinal range centre (C), or southern edge (S) Population: location from which individuals were collected (see Fig. 1 and Table 1 in publication) Line: artificial selection line; early flowering (early); unselected (control); late flowering (late) Population.Line: selection line nested within population Par1: identity of parent 1 of each individual in 2013 and 2014 generations; used in calculations of weighted selection differentials Par2: identity of parent 2 of each individual in 2013 and 2014 generations; used in calculations of weighted selection differentials Family: full-sibling seed family Replicate: replicates of each full-sibling seed family; only relevant in 2013 and 2014 generations Family.Replicate: replicate nested within full-sibling seed family; only relevant in 2013 and 2014 generations FloweringTime: number of days from germination to first flower SLA: specific leaf area (mm2/mg); only measured in 2014 generation percent.N: percent leaf nitrogen content; only measured in 2014 generation on a subset of individuals RGR: relative growth rate in early seedling stem length (cm cm-1 day-1); only measured in 2014 generation delta.13C: carbon isotope ratio (δ13C); only measured in 2014 generation on a subset of individuals

This data file includes unique IDs for the Mimulus cardinalis individuals selected for early flowering, late flowering, and unselected control lines in the 2012 and 2013 generations. Column names are as follows: Generation: year in which artificial selection was performed; parental generation (2012); 1 generation of selection (2013); 2 generations of selection (2014) Region: range position from which populations originate; northern edge (N), latitudinal range centre (C), or southern edge (S) Population: location from which individuals were collected (see Fig. 1 and Table 1 in publication) Line: artificial selection line; early flowering (early); unselected (control); late flowering (late) Population.Line: selection line nested within population ID: full-sibling seed family (in the case of data from the 2012 generation) or replicate nested within full-sibling seed family (in the case of data from the 2013 generation) FloweringTime: number of days from germination to first flower

This data file includes flowering time, measured as number of days from germination to first flower, for each Mimulus cardinalis individual in artificial selection experiment based on a subset of individuals from the C1 population (see publication for further details). Column names are as follows: Generation: year in which artificial selection was performed; parental generation (2012); 1 generation of selection (2013); 2 generations of selection (2014) Line: artificial selection line; early flowering (early); unselected (control); late flowering (late) Family: full-sibling seed family Replicate: replicates of each full-sibling seed family; only relevant in 2013 and 2014 generations Family.Replicate: replicate nested within full-sibling seed family; only relevant in 2013 and 2014 generations FloweringTime: number of days from germination to first flower

This data file includes unique IDs for the Mimulus cardinalis individuals selected for early flowering, late flowering, and unselected control lines in the 2012 and 2013 generations. Data are derived from artificial selection experiment based on a subset of individuals from the C1 population (see publication for further details). Column names are as follows: Generation: year in which artificial selection was performed; parental generation (2012); 1 generation of selection (2013); 2 generations of selection (2014) Line: artificial selection line; early flowering (early); unselected (control); late flowering (late) ID: full-sibling seed family (in the case of data from the 2012 generation) or replicate nested within full-sibling seed family (in the case of data from the 2013 generation) FloweringTime: number of days from germination to first flower
