Chevalier, M., Chase, B. M., Quick, L. J., Dupont, L. M., & Johnson, T. C. (2020). Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology. doi:10.1130/g47841.1 https://doi.org/10.1130/G47841.1

Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…

Lindberg, C. L., Hanslin, H. M., Schubert, M., Marcussen, T., Trevaskis, B., Preston, J. C., & Fjellheim, S. (2020). Increased above ground resource allocation is a likely precursor for independent evolutionary origins of annuality in the Pooideae grass subfamily. New Phytologist. doi:10.1111/nph.16666 https://doi.org/10.1111/nph.16666

Semelparous annual plants flower a single time during their one‐year life cycle, investing much of their energy into rapid reproduction. In contrast, iteroparous perennial plants flower multiple times over several years, and partition their resources between reproduction and persistence. To which ex…

Van Treuren, R., Hoekstra, R., Wehrens, R., & van Hintum, T. (2020). Effects of climate change on the distribution of crop wild relatives in the Netherlands in relation to conservation status and ecotope variation. Global Ecology and Conservation, 23, e01054. doi:10.1016/j.gecco.2020.e01054 https://doi.org/10.1016/j.gecco.2020.e01054

Crop wild relatives (CWR) are wild plant taxa that are genetically related to a cultivated species and are considered rich sources of useful traits for crop improvement. CWR are generally underrepresented in genebanks, while their survival in nature is not guaranteed. Inventories and risk analyses a…

Goodwin, Z. A., Muñoz-Rodríguez, P., Harris, D. J., Wells, T., Wood, J. R. I., Filer, D., & Scotland, R. W. (2020). How long does it take to discover a species? Systematics and Biodiversity, 1–10. doi:10.1080/14772000.2020.1751339 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 …

Carrasco, J., Price, V., Tulloch, V., & Mills, M. (2020). Selecting priority areas for the conservation of endemic trees species and their ecosystems in Madagascar considering both conservation value and vulnerability to human pressure. Biodiversity and Conservation. doi:10.1007/s10531-020-01947-1 https://doi.org/10.1007/s10531-020-01947-1

Madagascar is one of the most biodiverse countries in Africa, due to its level of endemism and species diversity. However, the pressure of human activities threatens the last patches of natural vegetation in the country and conservation decisions are undertaken with limited data availability. In thi…

Khoury, C. K., Carver, D., Barchenger, D. W., Barboza, G. E., Zonneveld, M., Jarret, R., … Greene, S. L. (2019). Modelled distributions and conservation status of the wild relatives of chile peppers ( Capsicum L.). Diversity and Distributions. doi:10.1111/ddi.13008 https://doi.org/10.1111/ddi.13008

Aim: To fill critical knowledge gaps with regard to the distributions and conservation status of the wild relatives of chile peppers (Capsicum L.). Location: The study covered the potential native ranges of currently recognized wild Capsicum taxa, throughout the Americas. Methods: We modelled the po…

Hawthorne, W. D., & Marshall, C. A. M. (2019). Rapid Botanic Survey, Bioquality and improving botanical inventory in the tropics by integrating across spatial scales. Gardens’ Bulletin Singapore, 71(suppl.2), 315–333. doi:10.26492/gbs71(suppl.2).2019-21 https://doi.org/10.26492/gbs71(suppl.2).2019-21

We review the Rapid Botanic Survey method (RBS), in the context of botanical recording to date. The concept of bioquality, a biodiversity value respecting global rarity, is summarised. Bioquality assessment involves the Star system for categorising species by global rarity; and a Genetic Heat Index …

Henareh Khalyani, A., Gould, W. A., Falkowski, M. J., Muscarella, R., Uriarte, M., & Yousef, F. (2019). Climate change increases potential plant species richness on Puerto Rican uplands. Climatic Change. doi:10.1007/s10584-019-02491-w https://doi.org/10.1007/s10584-019-02491-w

Modeling climate change effects on species and communities is critical especially in isolated islands. We analyzed the potential effects of climate change on 200 plant species in Puerto Rico under two emission scenarios and in four periods over the twenty-first century. Our approach was based on ens…

Margaroni, S., Petersen, K. B., Gleadow, R., & Burd, M. (2019). The role of spore size in the global pattern of co-occurrence among Selaginella species. Journal of Biogeography. doi:10.1111/jbi.13532 https://doi.org/10.1111/jbi.13532

Aim: Separation of regeneration niches may promote coexistence among closely related plant species, but there is little evidence that regeneration traits affect species ranges at broad geographical scales. We address patterns of co‐occurrence within the genus Selaginella, an ancient lineage of free‐…
