Pollen flow and effects of population structure on selfing rates and female and male reproductive success in fragmented Magnolia stellata populations

Table 2 The intercept and parameters included in the best and other models (according to Akaike’s Information Criterion, AIC) explaining the female reproductive success and selfing rate of Magnolia stellata offspring

4	c, maternal genet size, local density (45 m), population size, neighboring population size	15799.9	33.8	c, local density (25 m)	301.7	2.2
5	c, local density (40 m), pulation size, neighboring population size	15805.4	39.3	c, maternal genet size, local density (30 m)	301.8	2.3

Abbreviations: ΔAIC, the difference in AIC between the model considered and the most parsimonious model; c, intercept. Numbers in the parentheses after local density are the radius used to calculate the local genet density.
