Goldstein, E. B., Mullins, E. V., Moore, L. J., Biel, R. G., Brown, J. K., Hacker, S. D., … Zinnert, J. C. (2018). Literature-based latitudinal distribution and possible range shifts of two US east coast dune grass species (Uniola paniculata and Ammophila breviligulata). PeerJ, 6, e4932. doi:10.7717/peerj.4932 https://doi.org/10.7717/peerj.4932

Previous work on the US Atlantic coast has generally shown that coastal foredunes are dominated by two dune grass species, Ammophila breviligulata (American beachgrass) and Uniola paniculata (sea oats). From Virginia northward, A. breviligulata dominates, while U. paniculata is the dominant grass so…

Joffard, N., Massol, F., Grenié, M., Montgelard, C., & Schatz, B. (2018). Effect of pollination strategy, phylogeny and distribution on pollination niches of Euro‐Mediterranean orchids. Journal of Ecology, 107(1), 478–490. doi:10.1111/1365-2745.13013 https://doi.org/10.1111/1365-2745.13013

1.Pollination niches are important components of ecological niches and have played a major role in the diversification of Angiosperms. In this study, we focused on Euro‐Mediterranean orchids, which use diverse pollination strategies and interact with various functional groups of insects. In these or…

Petersen, K. B., & Burd, M. (2018). The adaptive value of heterospory: Evidence from Selaginella . Evolution, 72(5), 1080–1091. doi:10.1111/evo.13484 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., & Heron, J. (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. doi:10.3897/bdj.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…
