ECOLOGY Correction for “Shifts in flowering phenology reshape a subalpine plant community,” by Paul J. CaraDonna, Amy M. Iler, and David W. Inouye, which was first published March 17, 2014; 10.1073/pnas.1323073111 (Proc Natl Acad Sci USA 111:4916–4921).
The authors note that Fig. 3 appeared incorrectly. The corrected figure and its legend appear below.
Fig. 3.
Community-level change in interaction potential over 39 y. Each cell represents the proportional change in interaction potential, or coflowering overlap, between species pairs over the 39-y study period (1974–2012). Coflowering was calculated annually as the total number of flowers of every species pair that overlap in time, divided by the total number of flowers of the focal species (see main text for an example). To represent change in coflowering visually for all species, we multiplied each rate of change by 39 y; thus, a proportional change of 0.25 indicates a 25% increase in overlap of a focal species with an interacting species over the course of our study period. Proportional changes in overlap values are binned (e.g., 0.25 = 0.01–0.25). Colored cells indicate significant changes in interaction potential through time (P ≤ 0.05), gray cells indicate no change, and white cells indicate cases in which species pairs did not coflower in any years of the study. Species are ordered by mean first flowering date (as in Fig. 2).
