Table 1.
Results of linear regression analysis of study site mean dates of three phenophases on altitude Numbers in bold are significant (P <0.05). Altitudinal ranges show the maximum difference in elevation and the elevation of the lowest and highest site for each species and phenophase. BF, beginning of flowering; FF, full flowering; EF, end of flowering; #, no variation recorded in this variable for this event.
