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…

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…

Sheffield, C., and J. Heron. 2018. A new western Canadian record of Epeoloides pilosulus (Cresson), with discussion of ecological associations, distribution and conservation status in Canada. Biodiversity Data Journal 6: e22837. https://doi.org/10.3897/bdj.6.e22837

Background: Epeoloides pilosulus, one of the rarest bees in North America, is a cleptoparasite of Macropis bees which themselves are uncommon oligoleges of oil-producing Lysimachia flowers. Only two specimens of the cleptoparasite have been reported from Canada since the 1960s, both from Nova Scotia…

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…

Ashraf, U., A. T. Peterson, M. N. Chaudhry, I. Ashraf, Z. Saqib, S. Rashid Ahmad, and H. Ali. 2017. Ecological niche model comparison under different climate scenarios: a case study ofOleaspp. in Asia. Ecosphere 8: e01825. https://doi.org/10.1002/ECS2.1825

Ecological niche modeling (and the related species distribution modeling) has been used as a tool with which to assess potential impacts of climate change processes on geographic distributions of species. However, the factors introducing variation into niche modeling outcomes are not well understood…

Groom, Q. J., I. Hoste, and S. Janssens. 2017. Observación confirmada de <em>Oxalis dillenii</em> en España. Collectanea Botanica 36: 004. https://doi.org/10.3989/collectbot.2017.v36.004

A confirmed observation of Oxalis dillenii in Spain.— We confirm the presence of Oxalis dillenii Jacq. in the Catalonian province Lleida (Catalonia, Spain). Identification was confirmed morphologically and through DNA barcode sequencing. A map of the distribution of O. dillenii is supplied, as are n…

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…

• All plant species in the region were Star rated (categories of global rarity) • A species distribution database was assembled for tropical African plants • A reliable minimum estimate of global irreplaceability was mapped across the region • The results allow global conservation values to be trans…
