| 1 | A tale of worldwide success:Behind the scenes of Carex(Cyperaceae)biogeography and diversification显示文摘The megadiverse genus Carex(c.2000 species,Cyperaceae)has a nearly cosmopolitan distribution,displaying an inverted latitudinal richness gradient with higher species diversity in cold-temperate areas of the Northern Hemisphere.Despite great expansion in our knowledge of the phylogenetic history of the genus and many molecular studies focusing on the biogeography of particular groups during the last few decades,a global analysis of Carex biogeography and diversification is still lacking.For this purpose,we built the hitherto most comprehensive Carex-dated phylogeny based on three markers(ETS-ITS-matK),using a previous phylogenomic Hyb-Seq framework,and a sampling of two-thirds of its species and all recognized sections.Ancestral area reconstaiction,biogeographic stochastic mapping,and diversification rate analyses were conducted to elucidate macroevolutionary biogeographic and diversification patterns.Our results reveal that Carex originated in the late Eocene in E Asia,where it probably remained until the synchronous diversification of its main subgeneric lineages during the late Oligocene.E Asia is supported as the cradle of Carex diversification,as well as a< | Santiago Martin-Bravo Pedro Jimenez-Mejias Tamara Villaverde Marcial Escudero Marlene Hahn Daniel Spalink Eric H.Roalson Andrew L.Hipp the Global Carex Group Carmen Benitez-Benitez Leo P.Bruederle Elisabeth Fitzek Bruce A.Ford Kerry A.Ford Mira Gamer Sebastian Gebauer Matthias H.Hoffmann Xiao-Feng Jin Isabel Larridon Etienne Ldveilld-Bourret Yi-Fei Lu Modesto Luceno Enrique Maguilla Jose Ignacio Marquez-Corro Monica Miguez Robert Naczi Anton A.Reznicek Julian R.Starr | 2019 | Journal of Systematics and Evolution2019，57，6： | 6 |
| 2 | Assessing the sensitivity of divergence time estimates to locus sampling, calibration points, and model priors in a RAD-seq phylogeny of Carex section Schoenoxiphium显示文摘Restriction site-associated DNA sequencing(RAD-seq)and related methods have become relatively common approaches to resolve species-level phylogeny.It is not clear,however,whether RAD-seq data matrices are well suited to relaxed clock inference of divergence times,given the size of the matrices and the abundance of missing data.We investigated the sensitivity of Bayesian relaxed clock estimates of divergence times to alternative analytical decisions on an empirical RAD-seq phylogenetic matrix.We explored the relative contribution of secondary calibration strategies,amount of missing data,and the data partition analyzed to overall variance in divergence times inferred using BEAST MCMC analyses of Carex section Schoenoxiphium(Cyperaceae)-a recent radiation for which we have nearly complete species sampling of RAD-seq data.The crown node for Schoenoxiphium was estimated to be 15.22(9.56-21.18)Ma using a single calibration point and low missing data,11.93(8.07-16.03)Ma using multiple calibration points and low missing data,and 8.34(5.41-11.22)using multiple calibrations but high missing data.We found that using matrices with more than half of the individuals with missing data inferred younger mean ages for all nodes.Moreover,we have found that our molecular clock estimates are sensitive to the positions of the calibration(s)in our phylogenetic tree(using matrices with low missing data),especially when only a single calibration was applied to estimate divergence times.These results argue for sensitivity analyses and caution in interpreting divergence time estimates from RAD-seq data. | Tamara Villaverde Enrique Maguilla Modesto Luceno Andrew L.Hipp | 2021 | Journal of Systematics and Evolution2021，59，4： | 3 |
