Wan, J.-Z., and C.-J. Wang. 2018. Expansion risk of invasive plants in regions of high plant diversity: A global assessment using 36 species. Ecological Informatics 46: 8–18. https://doi.org/10.1016/j.ecoinf.2018.04.004

Invasive plant species (IPS) have a high potential for expanding within biodiversity hotspots and threatening global plant diversity. Hence, it is urgent to assess the expansion risk of IPS in regions of high plant diversity and their potentially negative effects throughout the world. We used the wo…

Lyam, P. T., J. Duque-Lazo, W. Durka, F. Hauenschild, J. Schnitzler, I. Michalak, O. T. Ogundipe, and A. N. Muellner-Riehl. 2018. Genetic diversity and distribution of Senegalia senegal (L.) Britton under climate change scenarios in West Africa T.-Y. Chiang [ed.],. PLOS ONE 13: e0194726. https://doi.org/10.1371/journal.pone.0194726

Climate change is predicted to impact species’ genetic diversity and distribution. We used Senegalia senegal (L.) Britton, an economically important species distributed in the Sudano-Sahelian savannah belt of West Africa, to investigate the impact of climate change on intraspecific genetic diversity…

Petersen, K. B., and M. Burd. 2018. The adaptive value of heterospory: Evidence from Selaginella. Evolution 72: 1080–1091. https://doi.org/10.1111/evo.13484

Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. We used the geographic distributions of 114 species of the heterosporous lycophyte Selaginella to explore the functional ecology of microspore and megaspore size, traits that would be corre…

Reichgelt, T., C. K. West, and D. R. Greenwood. 2018. The relation between global palm distribution and climate. Scientific Reports 8. https://doi.org/10.1038/s41598-018-23147-2

Fossil palms provide qualitative evidence of (sub-) tropical conditions and frost-free winters in the geological past, including modern cold climate regions (e.g., boreal, or polar climates). The freeze intolerance of palms varies across different organs and life stages, with seedlings in particular…

Caudullo, G., E. Welk, and J. San-Miguel-Ayanz. 2017. Chorological maps for the main European woody species. Data in Brief 12: 662–666. https://doi.org/10.1016/j.dib.2017.05.007

A novel chorological data compilation for the main European tree and shrub species is presented. This dataset was produced by combining numerous and heterogeneous data collected from 20th century atlas monographs providing complete species distribution maps, and from more recent national to regional…

Grossenbacher, D. L., Y. Brandvain, J. R. Auld, M. Burd, P. Cheptou, J. K. Conner, A. G. Grant, et al. 2017. Self‐compatibility is over‐represented on islands. New Phytologist 215: 469–478. https://doi.org/10.1111/nph.14534

Because establishing a new population often depends critically on finding mates, individuals capable of uniparental reproduction may have a colonization advantage. Accordingly, there should be an over-representation of colonizing species in which individuals can reproduce without a mate, particularl…

Antonelli, A., H. Hettling, F. L. Condamine, K. Vos, R. H. Nilsson, M. J. Sanderson, H. Sauquet, et al. 2016. Toward a Self-Updating Platform for Estimating Rates of Speciation and Migration, Ages, and Relationships of Taxa. Systematic Biology: syw066. https://doi.org/10.1093/sysbio/syw066

Rapidly growing biological data –including molecular sequences and fossils– hold an unprecedented potential to reveal how evolutionary processes generate and maintain biodiversity. However, researchers often have to develop their own idiosyncratic workflows to integrate and analyse these data for re…
