Schubert, M., Marcussen, T., Meseguer, A. S., & Fjellheim, S. (2019). The grass subfamily Pooideae: Cretaceous–Palaeocene origin and climate‐driven Cenozoic diversification. Global Ecology and Biogeography. doi:10.1111/geb.12923 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. …

Folk, R. A., Stubbs, R. L., Mort, M. E., Cellinese, N., Allen, J. M., Soltis, P. S., … Guralnick, R. P. (2019). Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences, 116(22), 10874–10882. doi:10.1073/pnas.1817999116 https://doi.org/10.1073/pnas.1817999116

Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. Such density-dependent models imply tight linkages between diversification and…

Karger, D. N., Kessler, M., Conrad, O., Weigelt, P., Kreft, H., König, C., & Zimmermann, N. E. (2019). Why tree lines are lower on islands-Climatic and biogeographic effects hold the answer. Global Ecology and Biogeography. doi:10.1111/geb.12897 https://doi.org/10.1111/geb.12897

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…

Liu, X., Blackburn, T. M., Song, T., Li, X., Huang, C., & Li, Y. (2019). Risks of Biological Invasion on the Belt and Road. Current Biology, 29(3), 499–505.e4. doi:10.1016/j.cub.2018.12.036 https://doi.org/10.1016/j.cub.2018.12.036

China’s Belt and Road Initiative (BRI) is an unprecedented global development program that involves nearly half of the world’s countries [1]. It not only will have economic and political influences, but also may generate multiple environmental challenges and is a focus of considerable academic and p…

Sullivan, J., Smith, M. L., Espíndola, A., Ruffley, M., Rankin, A., Tank, D., & Carstens, B. (2019). Integrating life history traits into predictive phylogeography. Molecular Ecology. doi:10.1111/mec.15029 https://doi.org/10.1111/mec.15029

Predictive phylogeography seeks to aggregate genetic, environmental and taxonomic data from multiple species in order to make predictions about unsampled taxa using machine‐learning techniques such as Random Forests. To date, organismal trait data have infrequently been incorporated into predictive …

Ansaldi, B. H., Franks, S. J., & Weber, J. J. (2018). The influence of environmental factors on breeding system allocation at large spatial scales. AoB PLANTS, 10(6). doi:10.1093/aobpla/ply069 https://doi.org/10.1093/aobpla/ply069

Plant breeding systems can vary widely among populations, yet few studies have investigated abiotic factors contributing to variation across a broad geographic range. Here we investigate variation in reproductive traits of Triodanis perfoliata (Campanulaceae), a species that exhibits dimorphic cleis…

Wan, J.-Z., Wang, C.-J., & Yu, F.-H. (2019). Large-scale environmental niche variation between clonal and non-clonal plant species: Roles of clonal growth organs and ecoregions. Science of The Total Environment, 652, 1071–1076. doi:10.1016/j.scitotenv.2018.10.280 https://doi.org/10.1016/j.scitotenv.2018.10.280

Clonal plant species can produce genetically identical and potentially independent offspring, and dominate a variety of habitats. The divergent evolutionary mechanisms between clonal and non-clonal plants are interesting areas of ecological research. A number of studies have shown that the environme…

Garroutte, M., Huettmann, F., Webb, C. O., & Ickert-Bond, S. M. (2018). Biogeographic and anthropogenic correlates of Aleutian Islands plant diversity: A machine-learning approach. Journal of Systematics and Evolution, 56(5), 476–497. doi:10.1111/jse.12456 https://doi.org/10.1111/jse.12456

This is the first comprehensive analysis of vascular plant diversity patterns in the Aleutian Islands to identify and quantify the impact of Aleutian Island distance dispersal barriers, geographical, ecological and anthropogenic factors. Data from public Open Access databases, printed floristic acco…

Inman, R., Franklin, J., Esque, T., & Nussear, K. (2018). Spatial sampling bias in the Neotoma paleoecological archives affects species paleo-distribution models. Quaternary Science Reviews, 198, 115–125. doi:10.1016/j.quascirev.2018.08.015 https://doi.org/10.1016/j.quascirev.2018.08.015

The ability to infer paleo-distributions with limited knowledge of absence makes species distribution modeling (SDM) a useful tool for exploring paleobiogeographic questions. Spatial sampling bias is a known issue when modeling extant species. Here we quantify the spatial sampling bias in a North Am…

John, G. P., Henry, C., & Sack, L. (2018). Leaf rehydration capacity: Associations with other indices of drought tolerance and environment. Plant, Cell & Environment, 41(11), 2638–2653. doi:10.1111/pce.13390 https://doi.org/10.1111/pce.13390

Clarifying the mechanisms of leaf and whole plant drought responses is critical to predict the impacts of ongoing climate change. The loss of rehydration capacity has been used for decades as a metric of leaf dehydration tolerance but has not been compared with other aspects of drought tolerance. We…
