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…

Jurd, D., and M. Pole. 2017. Miocene “fin-winged” fruits and Pliocene drift fruits – the first record of Combretaceae (Terminalia) from New Zealand. Geobios 50: 423–429. https://doi.org/10.1016/j.geobios.2017.10.002

Two types of fossil Terminalia (Combretaceae) fruits are described from warmer periods in New Zealand’s past. One is represented by large ‘fin-winged’ fruit (samara) from the Early Miocene Manuherikia Group sediments of Bannockburn and the Nevis Valley. The form and size of the fruits are entirely u…

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…

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…
