Brightly, W. H., S. E. Hartley, C. P. Osborne, K. J. Simpson, and C. A. E. Strömberg. 2020. High silicon concentrations in grasses are linked to environmental conditions and not associated with C 4 photosynthesis. Global Change Biology 26: 7128–7143. https://doi.org/10.1111/gcb.15343

The uptake and deposition of silicon (Si) as silica phytoliths is common among land plants and is associated with a variety of functions. Among these, herbivore defense has received significant attention, particularly with regards to grasses and grasslands. Grasses are well known for their high sili…

Chevalier, M., B. M. Chase, L. J. Quick, L. M. Dupont, and T. C. Johnson. 2020. Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology 49: 71–75. 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…

Albuquerque, F., M. Á. Macías-Rodríguez, A. Búrquez, and H. Rowe. 2020. Toward an understanding of broad-scale patterns of the habitat suitability of fountain grass (Cenchrus setaceus (Forssk.) Morrone, Poaceae). Plant Ecology 221: 1029–1043. https://doi.org/10.1007/s11258-020-01060-x

Understanding the factors contributing to the introduction and spread of invasive species is crucial to help develop management strategies to control and eradicate them in sensitive areas. Our goals were to investigate (1) the association between habitat suitability of fountain grass (Cenchrus setac…

Li, K., J. Wang, L. Qiao, R. Zheng, Y. Ma, Y. Chen, X. Hou, et al. 2020. Diversity of Reproductive Phenology Among Subtropical Grasses Is Constrained by Evolution and Climatic Niche. Frontiers in Ecology and Evolution 8. https://doi.org/10.3389/fevo.2020.00181

Reproductive phenology is sensitive to climatic changes and is associated with species functional types, distribution ranges, and their corresponding climatic niches. Phylogenetic niche conservatism in reproductive phenology also constrains its diversity and the distribution of species. Therefore, w…

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…

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) …

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…

Kass, J. M., R. P. Anderson, A. Espinosa‐Lucas, V. Juárez‐Jaimes, E. Martínez‐Salas, F. Botello, G. Tavera, et al. 2019. Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in Mexico. Ecography 43: 341–352. https://doi.org/10.1111/ecog.04886

Although long‐standing theory suggests that biotic variables are only relevant at local scales for explaining the patterns of species’ distributions, recent studies have demonstrated improvements to species distribution models (SDMs) by incorporating predictor variables informed by biotic interactio…
