POPULATION BIOLOGY Correction for “Fast–slow continuum and reproductive strategies structure plant life-history variation worldwide,” by Roberto Salguero-Gómez, Owen R. Jones, Eelke Jongejans, Simon P. Blomberg, David J. Hodgson, Cyril Mbeau-Ache, Pieter A. Zuidema, Hans de Kroon, and Yvonne M. Buckley, which was first published December 22, 2015; 10.1073/pnas.1506215112 (Proc Natl Acad Sci USA 113:230–235).
The authors note that the symbols “greater than” and “lower than” of the survivorship curve type (H) in Table 1 appeared incorrectly. The corrected table appears below. This error does not affect the results or conclusions of the article.
Table 1.
Loadings of the life-history traits grouped by their relation to turnover, and strategies to longevity, growth, and reproduction onto the first two PCA axes
| Life-history trait | Symbol | Definition | PCA 1 | PCA 2 |
| Turnover | T | Number of years necessary for the individuals of a population to be fully replaced by new ones | 0.85 | 0.17 |
| Generation time | ||||
| Longevity | H | Shape of the age-specific survivorship curve lx as quantified by Keyfitz’ entropy (H). H <1, =1, >1 correspond to survivorship curves types I, II and III, respectively | 0.55 | 0.23 |
| Survivorship curve type | ||||
| Age at sexual maturity | Lα | Number of years that it takes an average individual in the population to become sexually reproductive | 0.71 | 0.29 |
| Growth | γ | Mean probability of transitioning to a larger/more developed stage in the life cycle of the species, weighted by the stable stage distribution (SSD) | −0.73 | −0.05 |
| Progressive growth | ||||
| Retrogressive growth | ρ | Mean probability of transitioning to a smaller/less developed stage in the life cycle of the species, SSD-weighted | 0.07 | −0.77 |
| Reproduction | Φ | Mean per-capita number of sexual recruits across stages in the life cycle of the species, SSD-weighted | −0.83 | 0.30 |
| Mean sexual reproduction | ||||
| Degree of iteroparity | S | Spread of reproduction throughout the lifespan of the individual as quantified by Demetrius’ entropy (S). High/low S values correspond to iteroparous/semelparous populations | −0.23 | 0.51 |
| Net reproductive rate | Ro | Mean number of recruits produced during the mean life expectancy of an individual in the population | 0.04 | 0.75 |
| Mature life expectancy | Lω | Number of years from the mean age at sexual maturity (Lα) until the mean life expectancy (ηe) of an individual in the population | 0.15 | 0.27 |
| Explained variation, % | 34.06 | 21.23 | ||
| Cumulative percentage of explained variation | 34.06 | 55.38 |
Loadings in bold indicate a high contribution (greater than ±0.50) of the life-history trait to the PCA axis.
