Notes: For each elevation, mean seedfall in each year was calculated from two seed traps and the summary statistics here use those annual means. Autocorrelation coefficients (ACFs) and partial autocorrelation coefficients (PACF) were examined for lag intervals up to five years; there were no significant PACFs and ACFs were only significant at one elevation for a one year lag (* = P < 0.05, N = 30 years). Mean correlation coefficient among raw seed production time series at the nine elevations was r = 0.84, df = 28, P< 0.0001 but the pairwise correlation coefficient was dependent upon spatial distance (i.e., elevational distance): correlation r = 0.992 0.001 × elevational distance(m).
