Supporting Information Table S2. Linear regression models examining the effects of time and locality on annual population growth rates (lnλ) in the long-term demography plots for two time periods. Locality x year interactions were not significant for any of the models.

For the first time period, data were available for only the five crater areas. Model for 1983-1987: n=25, R2=0.062; model for 1994-2010: n=87, R2=0.133. 2 Plots grouped into two elevational zones: low = the five cinder cone localities on crater floor (2260 to 2387 m), and high = the west rim locality (2908 m). Data for the high elevation locality available only for the second time period. Model for 1983-1987: n = 5, R2=0.038; model for 1994-2010: n=31, R2=0.31.
