Table 4 Inbreeding depression for survival (IDsurv) and DBH (IDgrowth) of the selfed progeny of E. globulus and E. ovata and comparison with other studies on E. globulus. Given is the trial location in Tasmania, Australia, estimates of IDgrowth and IDsurv, design of the experiment, and the native race of origin of the maternal trees. Experimental designs indicated as ‘plot’ corresponds to the planting of selfs and outcrosses in separate plots within a replicate thus avoiding competition between them, whereas “mixed” experimental designs correspond to the planting of self and outcrossed progeny intermixed in the same plot and thus selfs are competing with outcrosses

From: Inbreeding depression and differential maladaptation shape the fitness trajectory of two co-occurring Eucalyptus species
