Figures S1-S4 from Actuarial senescence in a long-lived orchid challenges our current understanding of ageing

Figure S1: Plots of the Kaplan-Meier estimators of the survivorship curves. Figure S2: Mortality and survivorship over age since first reproduction, and parameter values, of the second-best fitting mortality model (logistic including reproductive investment and no Makeham term). Figure S3: Mortality, survivorship and parameter values of the best-fitting mortality model that did not include reproductive investment (the third-best fitting model overall; logistic with a Makeham term). Figure S4: Predictions of senescence rates from the best-fitting Weibull model with reproductive investment accounted for, and predictions from the best-fitting logistic model excluding reproductive investment

The representation of terrestrial vertebrate species held in ISIS zoos.

<p>The upper panel summarizes the representation of species for each taxonomic class of terrestrial vertebrates while the four lower panels summarize representation at the taxonomic order level within each class. The length of each bar is proportional to the number of species held, and each bar is color-coded by class. The darker shaded region of each bar represents the number of species that fall into the three IUCN Red List threatened categories (Vulnerable, Endangered and Critically Endangered). The number of species in each category is indicated to the right of each bar, and the percentage of these that are threatened is given in parentheses.</p

Number of species assessed in the IUCN Red List and number of species held in ISIS zoos for each taxonomic class of terrestrial vertebrates.

*<p>The IUCN Red List refers to the categories of VU, EN and CR collectively as threatened species.</p>†<p>The reptile assessment by IUCN is not yet complete, so these results only refer to the species assessed in the IUCN Red List version 3.2 (2009).</p

Optimal radial distance between zoos in a metapopulation network for each taxonomic class of terrestrial vertebrates.

<p>Optimal radial distance between zoos, average probability of reaching the metapopulation size threshold within that radial distance, average number of zoos within radial distance and average number of zoos within radial distance that hold the threatened species. The optimal radial distance represents the distance needed to optimize the probability of reaching an average metapopulation size within the shortest possible distance between zoos (the metapopulation thresholds <i>m</i> are >50, >100 and >250 individuals). The column for “number of species in cluster” indicates the number of threatened species for which all ISIS zoos have at least <i>m</i> individuals.</p
