Drivers of intraspecific differentiation of the alpine cold tolerant herb Notopterygium oviforme: the roles of isolation by distance and ecological factors
<p>Determining the driver mechanisms of phenotypic and genetic divergence of species have long been the central topic in evolutionary biology. However, the relative roles of isolation by distance (IBD) and environment factors in contributing to species divergence is largely undetermined in perennial herbs in East Asia. In this study, we collected population genetic samples of a cold-tolerant perennial herb <i>Notopterygium oviforme</i> in central China. We integrated the population transcriptomes, whole chloroplast genomes, genotyping-by-sequencing, microsatellite markers and ecological environment factors to determine the relative contributions of geography, climatic and soil factors on genetic, chemical and phenotypic trait divergence. The clearly genetic distinction was identified between the west Qinling (WQ) and east Qinling Mountains (EQ) geographical groups within<i> N. oviforme</i>. Interestingly, the two groups have existed the obviously niche conservatism, which might have caused the similarity of most leaf functional traits. Multiple matrix regression with randomization analysis showed that the spatial pattern of intraspecific divergence mainly resulted from effect of IBD, not isolation by environment. Meanwhile, transcriptomic expression divergence and some ecological factors have played the key roles in differentiation of intraspecific lineage. Approximate Bayesian Computation showed that both lineages have experienced the historically population expansion, and the recent range contraction. Molecular dating suggested that the intraspecific divergence was closely associated with the dramatically uplifts of the Qinling Mountains in East Asia. These results demonstrated that the geography, geological and environmental factors together shaped the cryptic intraspecific diversification and population dynamics shifts of<i> </i>perennial cold tolerant herb.</p>

Data from: Differential niche modification by males and females of a dioecious herb: extending the Jack Sprat effect
Males and females of dioecious plants often differ in morphological, physiological, and life-history traits, probably as a result of their different requirements for reproduction. Here, we show that the growth and reproductive effort of individuals of the dioecious herb Mercurialis annua depended on whether males or females had been growing in the soil previously. This suggests that males and females of M. annua differentially modify the soil in which they are growing. Our study indicates that sexual dimorphism in dioecious plants can give rise to increased environmental heterogeneity as a consequence of sex-specific niche modification.
Simultaneous selection on vegetative and reproductive phenology in a perennial herb
<p>The timing of different life history events are often correlated, and selection might only rarely be exerted independently on the timing of a single event. In plants, phenotypic selection has often been shown to favour earlier flowering. However, little is known about to what extent this selection acts directly vs. indirectly via vegetative phenology, and if selection on the two traits is correlational. We estimated direct, indirect and correlational phenotypic selection on vegetative and reproductive phenology over three years for flowering individuals of the perennial herb <em>Lathyrus vernus</em>. Direct selection favoured earlier flowering and shorter timespans between leaf-out and flowering in all years. However, early flowering was associated with early leaf-out, and the direction of selection on leaf-out day varied among years. As a result, selection on leaf-out weakened selection for early flowering in one of the study years. We found no evidence of correlational selection. Our results highlight the importance of including temporally correlated traits when exploring selection on the phenology of seasonal events.</p>
