Plant breeding systems can vary widely among populations, yet few studies have investigated abiotic factors contributing to variation across a broad geographic range. Here we investigate variation in reproductive traits of Triodanis perfoliata (Campanulaceae), a species that exhibits dimorphic cleis…

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…

Zhou, W., X. Ji, S. Obata, A. Pais, Y. Dong, R. Peet, and Q.-Y. (Jenny) Xiang. 2018. Resolving relationships and phylogeographic history of the Nyssa sylvatica complex using data from RAD-seq and species distribution modeling. Molecular Phylogenetics and Evolution 126: 1–16. https://doi.org/10.1016/j.ympev.2018.04.001

Nyssa sylvatica complex consists of several woody taxa occurring in eastern North America. These taxa were recognized as two or three species including three or four varieties by different authors. Due to high morphological similarities and complexity of morphological variation, classification and d…
