Data from: Pollen limitation in the endangered Chinese endemic species Sinocalycanthus chinensis
<p>Pollen limitation negatively impacts endangered and endemic plants with small fragmented populations, such as <i>S</i><i>inocalycanthus chinensis</i><i>, </i>an endangered plant endemic to China. In this study, we analyzed the pollen limitation of the <i>S. chinensis</i> Damingshan (DMS) population in 2006, 2009, and 2010, and crossed plants with mates separated by different distances, both within and between populations. The DMS population exhibited strong pollen limitation in fruit set, seed set, and seeds per fruit in 2006, 2009, and 2010. The average accumulated pollen limitation (for fruit set times seeds per fruit) was 0.510 ± 0.180. Progeny crossed with pollen from intermediate neighboring plants within the same population (separated by 30 – 50 m from pollen recipients) had the lowest fitness. No optimal outcrossing distance was found within the<i> </i>DMS population. Progeny from crosses with the SXW and DLS populations performed relatively better, while those from crosses with QLF and LXS populations performed worse. Compared with average reproductive success, outbreeding depression was found in progeny from crosses with the LXS and QLF populations. Reproductive success from pure self-pollination indicated <i>S. chinensis </i>is self-compatible. Geitonogamous selfing increased reproductive success. Based on geitonogamous selfing, the proportion of selfed offspring was relatively high. These results provide basic references for the conservation of this species.</p>

Data from: Reproductive isolation and the maintenance of species boundaries 1 in two serpentine endemic Jewelflowers
Speciation occurs when reproductive barriers substantially reduce gene flow between lineages. Understanding how specific barriers contribute to reproductive isolation offers insight into the initial forces driving divergence, and the evolutionary and ecological processes responsible for maintaining diversity. Here we quantified multiple pre- and post-pollination isolating barriers in a pair of closely related California Jewelflowers (Streptanthus, Brassicaceae) living in an area of sympatry. S. breweri and S. hesperidis are restricted to similar serpentine habitats, however populations are spatially isolated at fine-scales and rarely co-occur in intermixed stands. Several intrinsic postzygotic barriers were among the strongest we quantified, however postzygotic barriers currently contribute little to overall reproductive isolation due to the cumulative strength of earlier-acting extrinsic barriers, including spatial isolation, and flowering time and pollinator differences. Data from multiple years suggest that pre-pollination barriers may have different strengths depending on annual environmental conditions. Similarly, crossing data suggest that the strength of intrinsic isolation may vary between different population pairs. Estimates of total reproductive isolation in S. breweri - S. hesperidis are robust to uncertainty and variability in individual barrier strength estimates, demonstrating how multiple barriers can act redundantly to prevent gene flow between close relatives living in sympatry.
