Davies, T. J., B. H. Daru, B. S. Bezeng, T. Charles-Dominique, G. P. Hempson, R. M. Kabongo, O. Maurin, et al. 2020. Savanna tree evolutionary ages inform the reconstruction of the paleoenvironment of our hominin ancestors. Scientific Reports 10. https://doi.org/10.1038/s41598-020-69378-0
Ideas on hominin evolution have long invoked the emergence from forests into open habitats as generating selection for traits such as bipedalism and dietary shifts. Though controversial, the savanna hypothesis continues to motivate research into the palaeo-environments of Africa. Reconstruction of t…
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 …
Ringelberg, J. J., N. E. Zimmermann, A. Weeks, M. Lavin, and C. E. Hughes. 2020. Biomes as evolutionary arenas: Convergence and conservatism in the trans‐continental succulent biome A. Moles [ed.],. Global Ecology and Biogeography 29: 1100–1113. https://doi.org/10.1111/geb.13089
Aim: Historically, biomes have been defined based on their structurally and functionally similar vegetation, but there is debate about whether these similarities are superficial, and about how biomes are defined and mapped. We propose that combined assessment of evolutionary convergence of plant fun…
Howard, C. C., and N. Cellinese. 2020. Tunicate bulb size variation in monocots explained by temperature and phenology. Ecology and Evolution 10: 2299–2309. https://doi.org/10.1002/ece3.5996
Plant bulbs are modified shoot systems comprised of short internodes with apical bud(s) surrounded by layers of leaf bases. Bulb diameters can vary greatly, with overall bulb size playing a role in flower formation and resource allocation. Despite the importance of bulb size to the overall fitness o…
Oyedeji Amusa, M. O., B.-E. Van Wyk, and A. Oskolski. 2020. Wood anatomy of South African Meliaceae: evolutionary and ecological implications. Botanical Journal of the Linnean Society 193: 165–179. https://doi.org/10.1093/botlinnean/boaa010
Wood structure in seven South African species of Ekebergia, Nymania, Trichilia and Turraea (Meliaceae) was studied and compared with data for other genera of the subfamily Melioideae to elucidate phylogenetic relationships and pathways of trait evolution in this group and to clarify the ecological s…
Pirie, M. D., M. Kandziora, N. M. Nürk, N. C. Le Maitre, A. Mugrabi de Kuppler, B. Gehrke, E. G. H. Oliver, and D. U. Bellstedt. 2019. Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica. BMC Evolutionary Biology 19. https://doi.org/10.1186/s12862-019-1545-6
Background: The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted interplay between geographical distance and ecological suitability of source and sink areas. Here, we test the influence of these factors on the dispersal history of the floweri…
Gamisch, A., and H. P. Comes. 2019. Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae). BMC Evolutionary Biology 19. https://doi.org/10.1186/s12862-019-1416-1
Background: Tropical rainforests (TRFs) harbour almost half of the world’s vascular plant species diversity while covering only about 6–7% of land. However, why species richness varies amongst the Earth’s major TRF regions remains poorly understood. Here we investigate the evolutionary processes sha…
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…
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…
