O’Connell, E., & Savage, J. (2020). Extended leaf phenology has limited benefits for invasive species growing at northern latitudes. Biological Invasions. doi:10.1007/s10530-020-02301-w https://doi.org/10.1007/s10530-020-02301-w

Many understory woody invasive plants in North America leaf out earlier or retain leaves later than their native associates. This extended leaf phenology is thought to grant invasive species an advantage over native species because spring and fall are crucial times for light access and carbon acquis…

Adhikari, S., Burke, I. C., & Eigenbrode, S. D. (2020). Mayweed chamomile ( Anthemis cotula L.) biology and management—A review of an emerging global invader. Weed Research. doi:10.1111/wre.12426 https://doi.org/10.1111/wre.12426

The globally invasive weed, mayweed chamomile (Anthemis cotula L.) is an annual, bushy, ill‐scented herb, originating in Eurasia. It is aggressively weedy in croplands, field‐side ditches, wet areas and along roadsides, especially in slightly acidic, nitrogen‐rich, clay‐loam soils. In addition to in…

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…

Grünig, M., Mazzi, D., Calanca, P., Karger, D. N., & Pellissier, L. (2020). Crop and forest pest metawebs shift towards increased linkage and suitability overlap under climate change. Communications Biology, 3(1). doi:10.1038/s42003-020-0962-9 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., 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 …

Reginato, M., Vasconcelos, T. N. C., Kriebel, R., & Simões, A. O. (2020). Is dispersal mode a driver of diversification and geographical distribution in the tropical plant family Melastomataceae? Molecular Phylogenetics and Evolution, 148, 106815. doi:10.1016/j.ympev.2020.106815 https://doi.org/10.1016/j.ympev.2020.106815

Species of plants with different life history strategies may differ in their seed dispersal mechanisms, impacting their distribution and diversification patterns. Shorter or longer distance dispersal is favored by different dispersal modes, facilitating (or constraining) population isolation, which …

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…

Li, M., He, J., Zhao, Z., Lyu, R., Yao, M., Cheng, J., & Xie, L. (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. doi:10.7717/peerj.8729 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., 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…

Gougherty, A. V., Chhatre, V. E., Keller, S. R., & Fitzpatrick, M. C. (2020). Contemporary range position predicts the range‐wide pattern of genetic diversity in balsam poplar ( Populus balsamifera L.). Journal of Biogeography. doi:10.1111/jbi.13811 https://doi.org/10.1111/jbi.13811

Aim: Patterns of genetic diversity within species’ ranges can reveal important insights into effects of past climate on species’ biogeography and current population dynamics. While numerous biogeographic hypotheses have been proposed to explain patterns of genetic diversity within species’ ranges, f…
