| 1 | Global dispersal and diversification of the genus Schoenus (Cyperaceae) from the Western Australian biodiversity hotspot显示文摘The predominantly austral genus Schoenus L.is the largest genus in tribe Schoeneae and one of the ten most species-rich Cyperaceae genera,with over 150 accepted species found mostly in Australia,New Zealand,southeast Asia,and southern Africa.Here,we use data based on two nuclear and three plastid DNA regions to present one of the most comprehensive phylogenetic reconstructions of a genus in Cyperaceae to date,covering over 70%of described species of Schoenus.After recent taxonomic realignments in the last 4 years have both added and removed species from the genus,we show that Schoenus is now monophyletic.In addition,our results indicate that Schoenus originated in Western Australia in the Paleocene and eventually dispersed to surrounding continents,but rarely back.The diversification rate of the genus appears to have slightly decreased over time,and there has not been an increase associated with the establishment of the Cape clade endemic to the sclerophyllous fynbos vegetation type,such as has been reported in other plant lineages endemic to the Cape region.These results will serve as a template to understanding the complex patterns of genome size evolution and to untangle drivers of diversification in this genus. | Tammy L.Elliott Ruan van Mazijk Russell L.Barrett Jeremy J.Bruhl Simon Joly Ngalirendwe Muthaphuli Karen L.Wilson A.Muthama Muasya | 2021 | Journal of Systematics and Evolution2021，59，4： | 2 |

| 4 | Population isolation shapes plant genetics, phenotype and germination in naturally patchy ecosystems显示文摘Aims Habitat connectivity is important in conservation since isolation can diminish the potential of a population for adaptation and increase its risk of extinction.However,conservation of naturally patchy ecosystems such as peatlands has mainly focused on preserving specific sites with exceptional characteristics,neglecting the poten-tial interconnectivity between patches.In order to better under-stand plant dynamics within a peatland network,we assessed the effect of population isolation on genetic distinctiveness,phenotypic variations and germination rates using the peatland-obligate white-fringed orchid(Platanthera blephariglottis).Methods Fifteen phenotypic traits were measured for 24 individuals per pop-ulation(20 distinct populations,Quebec,Canada)and germination rates of nearly 20000 seeds were assessed.Genetic distinctiveness was quantified for 26 populations using single nucleotide polymor-phism markers obtained via a pooled genotyping-by-sequencing approach.Geographic isolation was measured as the distance to the nearest population and as the number of populations occurring in concentric buffer zones(within a radius of 2,5 and 10 km)around the studied populations.Important Findings All phenotypic traits showed significant differences among popu-lations.Genetic results also indicated a pattern of isolation-by-distance,which suggests that seed and/or pollen exchange is restricted geographically.Finally,all phenotypic traits,as well as a reduced germination rate,were correlated with either geographic isolation or genetic distance.We conclude that geographic iso-lation likely restricts gene flow,which in turn may affect germi-nation.Consequently,it is imperative that conservation programs take into account the patchy nature of such ecosystems,rather than targeting a few specific sites with exceptional character for preservation. | Laurent De Vriendt Marc-AndréLemay Martine Jean Sébastien Renaut Stéphanie Pellerin Simon Joly François Belzile Monique Poulin | 2017 | Journal of Plant Ecology2017，10，4： | 0 |
