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…
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 …
Klages, J. P., U. Salzmann, T. Bickert, C.-D. Hillenbrand, K. Gohl, G. Kuhn, et al. 2020. Temperate rainforests near the South Pole during peak Cretaceous warmth. Nature 580: 81–86. 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., 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…
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…
Marconi, L., and L. Armengot. 2020. Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment 287: 106664. https://doi.org/10.1016/j.agee.2019.106664
In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…
Nevado, B., E. L. Y. Wong, O. G. Osborne, and D. A. Filatov. 2019. Adaptive Evolution Is Common in Rapid Evolutionary Radiations. Current Biology 29: 3081-3086.e5. https://doi.org/10.1016/j.cub.2019.07.059
One of the most long-standing and important mysteries in evolutionary biology is why biological diversity is so unevenly distributed across space and taxonomic lineages. Nowhere is this disparity more evident than in the multitude of rapid evolutionary radiations found on oceanic islands and mountai…
Fletcher, T. L., L. Warden, J. S. Sinninghe Damsté, K. J. Brown, N. Rybczynski, J. C. Gosse, and A. P. Ballantyne. 2019. Evidence for fire in the Pliocene Arctic in response to amplified temperature. Climate of the Past 15: 1063–1081. https://doi.org/10.5194/cp-15-1063-2019
The mid-Pliocene is a valuable time interval for investigating equilibrium climate at current atmospheric CO2 concentrations because atmospheric CO2 concentrations are thought to have been comparable to the current day and yet the climate and distribution of ecosystems were quite different. One intr…
Schubert, M., T. Marcussen, A. S. Meseguer, and S. Fjellheim. 2019. The grass subfamily Pooideae: Cretaceous–Palaeocene origin and climate‐driven Cenozoic diversification G. Jordan [ed.],. Global Ecology and Biogeography. https://doi.org/10.1111/geb.12923
Aim: Frost is among the most dramatic stresses a plant can experience, and complex physiological adaptations are needed to endure long periods of sub‐zero temperatures. Owing to the need to evolve these complex adaptations, transitioning from tropical to temperate climates is regarded as difficult. …
Schubert, M., L. Grønvold, S. R. Sandve, T. R. Hvidsten, and S. Fjellheim. 2019. Evolution of Cold Acclimation and Its Role in Niche Transition in the Temperate Grass Subfamily Pooideae. Plant Physiology 180: 404–419. https://doi.org/10.1104/pp.18.01448
The grass subfamily Pooideae dominates the grass floras in cold temperate regions, and has evolved complex physiological adaptations to cope with extreme environmental conditions like frost, winter and seasonality. One such adaptation is cold acclimation, wherein plants increase their frost toleranc…
