Taxonomic similarity does not predict necessary sample size for ex situ conservation: a comparison among five genera
<p>Effectively conserving biodiversity with limited resources requires scientifically informed and efficient strategies. Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. We investigated this question for 11 taxa across five genera. In this first study analyzing and optimizing ex situ genetic diversity across multiple genera, we found that the percentage of extant genetic diversity currently conserved varies among taxa, from 40 to 95%. Most taxa are well below genetic conservation targets. Resampling datasets showed that ideal collection sizes vary widely even within a genus: one taxon typically required at least 50% more individuals than another (though Quercus was an exception). Still, across taxa, the minimum collection size to achieve genetic conservation goals is within one order of magnitude. Current collections are also suboptimal: they could remain the same size yet capture twice the genetic diversity with improved sampling design. We term this deficiency the "genetic conservation gap." Lastly, we show that minimum collection sizes are influenced by collection priorities regarding the genetic diversity target. In summary, current collections are insufficient (not reaching targets) and suboptimal (not efficiently designed), and we show how improvements can be made.</p>
Data for: Shifts in plant-invertebrate interactions between wild and ex-situ conservation populations of a critically endangered tree
<p>Ex-situ conservation is an effective approach to prevent the extinction of endangered species. Biotic interactions (eg herbivory and pollination) are critical to ex-situ conservation success, including plant establishment, survival, and reproduction. However, shifts in biotic interactions between wild and ex-situ populations are still poorly understood. We compared herbivory and pollination characteristics between the only wild population (WP) and three ex-situ populations (LP, local population, nearby WP; NP, north population, ca. 850 km; and SP, south population, ca. 750 km) of a critically endangered tree species (<em>Sinojackia huangmeiensis</em>) to explore the latitudinal changes in plant-invertebrate interactions. Larvae of the Limacodidae family were the dominant herbivores in WP, LP, and NP, while the only herbivore observed in SP was a snail. Compared to WP, the leaf herbivory rate was unchanged in LP but decreased in NP and SP. Leaf defense traits (total phenols, tannins, leaf thickness, and leaf dry matter content) increased or remained unchanged in the three ex-situ populations. A pollinator (<em>Apis cerana</em>) of <em>S. huangmeiensis</em> was present in the four populations. NP and SP lacked some pollinators that were found in both WP and LP, but they shared one pollinator that was not observed in WP and LP. The pollinator visiting frequency increased in SP, while it did not change significantly in LP and NP. Synthesis and applications: Our results suggested that both herbivory and pollination of <em>S. huangmeiensis</em> changed in ex-situ populations, with complete or partial changes in herbivores, leaf herbivory rate, pollinators, pollinator visiting frequency, and fruit set in the two distant ex-situ populations. This work provides a unique empirical study of shifts in both antagonistic and mutualistic biotic interactions between wild and ex-situ populations. We emphasized that it is essential to integrate herbivore and pollinator management in future ex-situ conservation of plant species.</p>
