Goodwin, Z. A., P. Muñoz-Rodríguez, D. J. Harris, T. Wells, J. R. I. Wood, D. Filer, and R. W. Scotland. 2020. How long does it take to discover a species? Systematics and Biodiversity 18: 784–793. https://doi.org/10.1080/14772000.2020.1751339

The description of a new species is a key step in cataloguing the World’s flora. However, this is only a preliminary stage in a long process of understanding what that species represents. We investigated how long the species discovery process takes by focusing on three key stages: 1, the collection …

Dyderski, M. K., D. Chmura, Ł. Dylewski, P. Horodecki, A. M. Jagodziński, M. Pietras, P. Robakowski, and B. Woziwoda. 2020. Biological Flora of the British Isles: Quercus rubra. Journal of Ecology 108: 1199–1225. https://doi.org/10.1111/1365-2745.13375

This account presents information on all aspects of the biology of Quercus rubra L. (Red Oak, Northern Red Oak; syn. Q. borealis, Q. maxima) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological …

Peyre, G., J. Lenoir, D. N. Karger, M. Gomez, A. Gonzalez, O. Broennimann, and A. Guisan. 2020. The fate of páramo plant assemblages in the sky islands of the northern Andes B. Jiménez‐Alfaro [ed.],. Journal of Vegetation Science 31: 967–980. https://doi.org/10.1111/jvs.12898

Aims: Assessing climate change impacts on biodiversity is a main scientific challenge, especially in the tropics, therefore, we predicted the future of plant species and communities on the unique páramo sky islands. We implemented the Spatially Explicit Species Assemblage Modelling framework, by i) …

Kovalchuk, I., M. Pellino, P. Rigault, R. van Velzen, J. Ebersbach, J. R. Ashnest, M. Mau, et al. 2020. The Genomics ofCannabisand Its Close Relatives. Annual Review of Plant Biology 71: 713–739. https://doi.org/10.1146/annurev-arplant-081519-040203

Cannabis sativa L. is an important yet controversial plant with a long history of recreational, medicinal, industrial, and agricultural use, and together with its sister genus Humulus, it represents a group of plants with a myriad of academic, agricultural, pharmaceutical, industrial, and social int…

Berg, C. S., J. L. Brown, and J. J. Weber. 2019. An examination of climate‐driven flowering‐time shifts at large spatial scales over 153 years in a common weedy annual. American Journal of Botany 106: 1435–1443. https://doi.org/10.1002/ajb2.1381

Premise: Understanding species’ responses to climate change is a critical challenge facing biologists today. Though many species are widespread, few studies of climate‐driven shifts in flowering time have examined large continuous spatial scales for individual species. And even fewer studies have ex…

Karger, D. N., M. Kessler, O. Conrad, P. Weigelt, H. Kreft, C. König, and N. E. Zimmermann. 2019. Why tree lines are lower on islands—Climatic and biogeographic effects hold the answer J. Grytnes [ed.],. Global Ecology and Biogeography 28: 839–850. https://doi.org/10.1111/geb.12897

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…

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…
