Angert et al. Desert Annuals Data

Phenotypic measurements of relative growth rate (RGR, measured based on change in leaf area per day) and water-use efficiency (as measured by carbon isotope discrimination, Delta, in ppm) for winter annual plants grown in a greenhouse common garden at Colorado State University. Note that Delta is negatively related to water-use efficiency. Design includes replicate individuals of up to 30 maternal families from each of 4-5 populations per each of 4 species. Species codes: STMI = Stylocline micropoides, PERE = Pectocarya recurvata, ERTE = Erodium texanum, ERLA = Eriophyllum lanosum. Population codes: TUMH = Tumamoc Hill, AZ; OPNM = Organ Pipe National Monument, AZ; SDNM = Sonoran Desert National Monument, AZ; SENT = Sentinel, AZ; RINC = Rincon Mountains, AZ; CALI = Californian populations (see manuscript for exact locations for each species). Climatic values for winter maximum temperature (Tmax_wt), winter minimum temperature (Tmin_wt), and winter precipitation (PPT_wt) were estimated based on latitude and longitude using the program ClimateWNA.
