Table 1.
Source population locality information and summary temperature data for each site. Temperature data were collected within populations at each site between 2010 and 2013 (Chambers and Emery 2016). Temperature treatments used in the experiment spanned the range of average temperatures experienced by natural populations in the field as well as higher temperatures that are expected by 2100 under climate change projections.
