Variation in tolerance to heterospecific pollen from a non-native congener depends on co-existence history of maternal and paternal source populations. [PDF]

open access: yesAm J Bot
Abstract Premise Plants in sympatric populations with congeners may have evolved tolerance to the negative effects of heterospecific pollen (HP) through selection on female or male reproductive traits. If so, then the degree of HP tolerance may vary depending on the co‐existence history of the maternal and paternal plant source populations.

Comparative Genomics and Phylogenetic Analyses of <i>Aquarius macrophyllus</i> and Related Genera in Alismataceae Based on Plastome Data. [PDF]

open access: yesEcol Evol
We sequenced the plastome of Aquarius macrophyllus and conducted a comparative analysis incorporating eight species from four related genera in Alismataceae. Phylogenetic analysis of Alismataceae elucidated that Alisma and Burnatia species were early diverged, followed by Hydrocleys and Limnocharis. The monophyly of Aquarius and its sister relationship

Growth-defense trade-offs promote habitat isolation between recently-diverged species. [PDF]

open access: yesEcol Evol
Growth–defense trade‐offs have long been implicated in tropical plant diversity, but how do these tradeoffs contribute to reproductive isolation? This study characterizes growth–defense trade‐offs between two recently diverged tropical plants and explore their role in maintaining strong habitat isolation.
