Hock, M., R. Hofmann, F. Essl, P. Pyšek, H. Bruelheide, and A. Erfmeier. 2020. Native distribution characteristics rather than functional traits explain preadaptation of invasive species to high‐UV‐B environments M. Carboni [ed.],. Diversity and Distributions 26: 1421–1438. https://doi.org/10.1111/ddi.13113
Aim: Alien species successfully colonize new ranges if they encounter favourable environmental conditions there and possess traits that match new challenges. Climate‐matching approaches comparing native and exotic ranges mostly consider temperature and precipitation niches of alien species, but have…
Lindberg, C. L., H. M. Hanslin, M. Schubert, T. Marcussen, B. Trevaskis, J. C. Preston, and S. Fjellheim. 2020. Increased above‐ground resource allocation is a likely precursor for independent evolutionary origins of annuality in the Pooideae grass subfamily. New Phytologist 228: 318–329. 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., R. Hoekstra, R. Wehrens, and T. van Hintum. 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. 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…
Grünig, M., D. Mazzi, P. Calanca, D. N. Karger, and L. Pellissier. 2020. Crop and forest pest metawebs shift towards increased linkage and suitability overlap under climate change. Communications Biology 3. https://doi.org/10.1038/s42003-020-0962-9
Global changes pose both risks and opportunities to agriculture and forestry, and biological forecasts can inform future management strategies. Here, we investigate potential land-use opportunities arising from climate change for these sectors in Europe, and risks associated with the introduction an…
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 …
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) …
Li, M., J. He, Z. Zhao, R. Lyu, M. Yao, J. Cheng, and L. Xie. 2020. Predictive modelling of the distribution of Clematis sect. Fruticella s. str. under climate change reveals a range expansion during the Last Glacial Maximum. PeerJ 8: e8729. https://doi.org/10.7717/peerj.8729
Background The knowledge of distributional dynamics of living organisms is a prerequisite for protecting biodiversity and for the sustainable use of biotic resources. Clematis sect. Fruticella s. str. is a small group of shrubby, yellow-flowered species distributed mainly in arid and semi-arid areas…
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…
Smith, A. L., T. R. Hodkinson, J. Villellas, J. A. Catford, A. M. Csergő, S. P. Blomberg, E. E. Crone, et al. 2020. Global gene flow releases invasive plants from environmental constraints on genetic diversity. Proceedings of the National Academy of Sciences 117: 4218–4227. https://doi.org/10.1073/pnas.1915848117
When plants establish outside their native range, their ability to adapt to the new environment is influenced by both demography and dispersal. However, the relative importance of these two factors is poorly understood. To quantify the influence of demography and dispersal on patterns of genetic div…
Léveillé-Bourret, É., B.-H. Chen, M.-È. Garon-Labrecque, B. A. Ford, and J. R. Starr. 2020. RAD sequencing resolves the phylogeny, taxonomy and biogeography of Trichophoreae despite a recent rapid radiation (Cyperaceae). Molecular Phylogenetics and Evolution 145: 106727. https://doi.org/10.1016/j.ympev.2019.106727
Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial …
