De La Pascua, D. R., Smith‐Winterscheidt, C., Dowell, J. A., Goolsby, E. W., & Mason, C. M. (2020). Evolutionary trade‐offs in the chemical defense of floral and fruit tissues across genus Cornus. American Journal of Botany, 107(9), 1260–1273. doi:10.1002/ajb2.1540 https://doi.org/10.1002/ajb2.1540

Premise: Defense investment in plant reproductive structures is relatively understudied compared to the defense of vegetative organs. Here the evolution of chemical defenses in reproductive structures is examined in light of the optimal defense, apparency, and resource availability hypotheses within…

Tan, K., Lu, T., & Ren, M.-X. (2020). Biogeography and evolution of Asian Gesneriaceae based on updated taxonomy. PhytoKeys, 157, 7–26. doi:10.3897/phytokeys.157.34032 https://doi.org/10.3897/phytokeys.157.34032

Based on an updated taxonomy of Gesneriaceae, the biogeography and evolution of the Asian Gesneriaceae are outlined and discussed. Most of the Asian Gesneriaceae belongs to Didymocarpoideae, except Titanotrichum was recently moved into Gesnerioideae. Most basal taxa of the Asian Gesneriaceae are fou…

O’Connell, E., & Savage, J. (2020). Extended leaf phenology has limited benefits for invasive species growing at northern latitudes. Biological Invasions. doi:10.1007/s10530-020-02301-w https://doi.org/10.1007/s10530-020-02301-w

Many understory woody invasive plants in North America leaf out earlier or retain leaves later than their native associates. This extended leaf phenology is thought to grant invasive species an advantage over native species because spring and fall are crucial times for light access and carbon acquis…

Folk, R. A., Stubbs, R. L., Mort, M. E., Cellinese, N., Allen, J. M., Soltis, P. S., … Guralnick, R. P. (2019). Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences, 116(22), 10874–10882. doi:10.1073/pnas.1817999116 https://doi.org/10.1073/pnas.1817999116

Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. Such density-dependent models imply tight linkages between diversification and…

Wan, J.-Z., Zhang, Z.-X., & Wang, C.-J. (2019). Effects of ecoregional vulnerability on habitat suitability of invasive alien plants: an assessment using 13 species on a global scale. Environmental Earth Sciences, 78(5). doi:10.1007/s12665-019-8186-3 https://doi.org/10.1007/s12665-019-8186-3

The development of new hypotheses can promote the explanation of mechanisms on plant invasion across different scales. We tested the hypothesis that ecoregional vulnerability can affect habitat suitability of invasive alien plants (IAPs) in non-native ranges. We used 13 IAPs, distributed around the …

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…
