Table 2.
Trait loadings on the first two principal components (PC) of a principal component analysis (PCA) with ten resource-use related traits in 30 winter annual species (see Figure 1).
| PC 1 | PC 2 | |
|---|---|---|
| Eigenvalue | 3.71 | 2.39 |
| Explained variance [%] | 37.1 | 23.9 |
| LTD | −0.47 | 0.06 |
| LDMC | −0.45 | 0.09 |
| Rdia | 0.46 | 0.06 |
| Lthick | 0.36 | 0.35 |
| SRL | −0.33 | 0.02 |
| RTD | −0.30 | −0.04 |
| SLA | 0.13 | −0.49 |
| Nmass | 0.09 | −0.49 |
| Cmass | −0.04 | −0.33 |
| Amass | −0.03 | −0.53 |
The table shows the eigenvalues, the proportion of explained variance of both PCs, and the loadings of the traits. Traits were ordered according to their |loading| on PC 1. Trait loadings > |0.4| are marked in bold.
