Background and Aims A large number of studies have attempted to determine the mechanisms driving plant diversity and distribution on a global scale, but the diverse and endemic alpine herbs found in harsh environments, showing adaptive evolution, require more studies. Methods Here, we selected 466 s…

Saldaña‐López, A., Vilà, M., Lloret, F., Manuel Herrera, J., & González‐Moreno, P. (2021). Assembly of species’ climatic niches of coastal communities does not shift after invasion. Journal of Vegetation Science, 32(2). doi:10.1111/jvs.12989 https://doi.org/10.1111/jvs.12989

Question: Do invasions by invasive plant species with contrasting trait profiles (Arctotheca calendula, Carpobrotus spp., Conyza bonariensis, and Opuntia dillenii) change the climatic niche of coastal plant communities? Location: Atlantic coastal habitats in Huelva (Spain). Methods: We identifi…

Brendel, M. R., Schurr, F. M., & Sheppard, C. S. (2020). Inter‐ and intraspecific selection in alien plants: How population growth, functional traits and climate responses change with residence time. Global Ecology and Biogeography. doi:10.1111/geb.13228 https://doi.org/10.1111/geb.13228

Aim: When alien species are introduced to new ranges, climate or trait mismatches may initially constrain their population growth. However, inter‐ and intraspecific selection in the new environment should cause population growth rates to increase with residence time. Using a species‐for‐time approac…

Büchi, L., Cordeau, S., Hull, R., & Rodenburg, J. (2020). Vulpia myuros , an increasing threat for agriculture. Weed Research. doi:10.1111/wre.12456 https://doi.org/10.1111/wre.12456

Vulpia myuros is an annual grass species of Mediterranean origin, which has achieved a global distribution. It is a fast‐growing species, with high colonisation and competitive abilities. This species is considered an invasive weed in most countries where it has been introduced, with highly negative…

Aim: Species distribution models (SDMs) are widely used to forecast potential range expansion of invasive species. However, invasive species occurrence datasets often have spatial biases that may violate key SDM assumptions. In this study, we examined alternative methods of spatial bias correction 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 …

Klages, J. P., Salzmann, U., Bickert, T., Hillenbrand, C.-D., Gohl, K., … Dziadek, R. (2020). Temperate rainforests near the South Pole during peak Cretaceous warmth. Nature, 580(7801), 81–86. doi:10.1038/s41586-020-2148-5 https://doi.org/10.1038/s41586-020-2148-5

The mid-Cretaceous period was one of the warmest intervals of the past 140 million years1,2,3,4,5, driven by atmospheric carbon dioxide levels of around 1,000 parts per million by volume6. In the near absence of proximal geological records from south of the Antarctic Circle, it is disputed whether p…

Ringelberg, J. J., Zimmermann, N. E., Weeks, A., Lavin, M., & Hughes, C. E. (2020). Biomes as evolutionary arenas: Convergence and conservatism in the trans‐continental succulent biome. Global Ecology and Biogeography. doi:10.1111/geb.13089 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…

Han, T., Zheng, Q., Onstein, R. E., Rojas‐Andrés, B. M., Hauenschild, F., Muellner‐Riehl, A. N., & Xing, Y. (2019). Polyploidy promotes species diversification of Allium through ecological shifts. New Phytologist. doi:10.1111/nph.16098 https://doi.org/10.1111/nph.16098

Despite the role of polyploidy in multiple evolutionary processes, its impact on plant diversification remains controversial. An increased polyploid frequency may facilitate speciation through shifts in ecology, morphology, or both. Here we used Allium to evaluate (1) the relationship between intras…

Duffy, K. J., & Jacquemyn, H. (2018). Climate change increases ecogeographical isolation between closely related plants. Journal of Ecology, 107(1), 167–177. doi:10.1111/1365-2745.13032 https://doi.org/10.1111/1365-2745.13032

1.Ecogeographic isolation is a fundamental prezygotic barrier to reproduction and a step toward diversification in flowering plants. However, whether ecogeographic isolation acts as a reproductive barrier between species and thus as a mechanism for species divergence is unclear and is expected to ch…
