Comparison of four approaches for fitting curves to data representing the relationship between freezing damage and temperature in (A, C, E, G) A. caudatifolium and (B, D, F, H) A. campestre stem segments (plots for other species provided in Additional file 1). Curves fit to data on a per-genotype (red, blue, and green) and per-species (black curve) basis are fit in each case. Panels show curves fit following the approach of A, B Anderson et al. [12], C, D Flint et al.[7], and Lim et al. [13]. Approaches vary, as indicated, in their use of room-temperature (zeroing; CH) and deep freezing (maximum damage; EH) controls and reliance on general logistic (AF) vs. Gompertz (GH) curves
