Key factor analysis of a population of the partridge Perdix perdixL. in England reported
by Blank et al. (1967). In (A), generational change (K= -R) and individual sources of mortality are
expressed as k-values: (k= -log(survival)) for each of eight sequential causes is plotted for each year
of the study. In (B) and (C) k-values are regressed against generational change (total K). Redrawn
from Podoler and Rogers (1975).
