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…

Smith, A. L., Hodkinson, T. R., Villellas, J., Catford, J. A., Csergő, A. M., Blomberg, S. P., … Buckley, Y. M. (2020). Global gene flow releases invasive plants from environmental constraints on genetic diversity. Proceedings of the National Academy of Sciences, 117(8), 4218–4227. doi:10.1073/pnas.1915848117 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…

De Siracusa, P. C., Gadelha, L. M. R., & Ziviani, A. (2020). New perspectives on analysing data from biological collections based on social network analytics. Scientific Reports, 10(1). doi:10.1038/s41598-020-60134-y https://doi.org/10.1038/s41598-020-60134-y

Biological collections have been historically regarded as fundamental sources of scientific information on biodiversity. They are commonly associated with a variety of biases, which must be characterized and mitigated before data can be consumed. In this work, we are motivated by taxonomic and colle…

Howard, C. C., & Cellinese, N. (2020). Tunicate bulb size variation in monocots explained by temperature and phenology. Ecology and Evolution. doi:10.1002/ece3.5996 https://doi.org/10.1002/ece3.5996

Plant bulbs are modified shoot systems comprised of short internodes with apical bud(s) surrounded by layers of leaf bases. Bulb diameters can vary greatly, with overall bulb size playing a role in flower formation and resource allocation. Despite the importance of bulb size to the overall fitness o…

Carrasco, J., Price, V., Tulloch, V., & Mills, M. (2020). Selecting priority areas for the conservation of endemic trees species and their ecosystems in Madagascar considering both conservation value and vulnerability to human pressure. Biodiversity and Conservation. doi:10.1007/s10531-020-01947-1 https://doi.org/10.1007/s10531-020-01947-1

Madagascar is one of the most biodiverse countries in Africa, due to its level of endemism and species diversity. However, the pressure of human activities threatens the last patches of natural vegetation in the country and conservation decisions are undertaken with limited data availability. In thi…

Asase, A., Sainge, M. N., Radji, R. A., Ugbogu, O. A., & Peterson, A. T. (2020). A new model for efficient, need‐driven progress in generating primary biodiversity information resources. Applications in Plant Sciences, 8(1). doi:10.1002/aps3.11318 https://doi.org/10.1002/aps3.11318

Premise: The field of biodiversity informatics has developed rapidly in recent years, with broad availability of large‐scale information resources. However, online biodiversity information is biased spatially as a result of slow and uneven capture and digitization of existing data resources. The Wes…

Pirie, M. D., Kandziora, M., Nürk, N. M., Le Maitre, N. C., Mugrabi de Kuppler, A., Gehrke, B., … Bellstedt, D. U. (2019). Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica. BMC Evolutionary Biology, 19(1). doi:10.1186/s12862-019-1545-6 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…

Kass, J. M., Anderson, R. P., Espinosa‐Lucas, A., Juárez‐Jaimes, V., Martínez‐Salas, E., Botello, F., … Sánchez‐Cordero, V. (2019). Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in Mexico. Ecography. doi:10.1111/ecog.04886 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…

Cámara-Leret, R., Raes, N., Roehrdanz, P., De Fretes, Y., Heatubun, C. D., Roeble, L., … Hannah, L. (2019). Climate change threatens New Guinea’s biocultural heritage. Science Advances, 5(11), eaaz1455. doi:10.1126/sciadv.aaz1455 https://doi.org/10.1126/sciadv.aaz1455

New Guinea is the most biologically and linguistically diverse tropical island on Earth, yet the potential impacts of climate change on its biocultural heritage remain unknown. Analyzing 2353 endemic plant species distributions, we find that 63% of species are expected to have smaller geographic ran…

Stull, G., Tiffney, B. H., Manchester, S. R., Rio, C. D., & Wing, S. L. (2019). Endocarps of Pyrenacantha (Icacinaceae) from the early Oligocene of Egypt. International Journal of Plant Sciences. doi:10.1086/706854 https://doi.org/10.1086/706854

The fossil record of Pyrenacantha (Phytocreneae tribe, Icacinaceae) includes well-documented species from the Paleogene of North and South America but, to date, no fossils have been described from its present geographic range, the Old World tropics. We document endocarp remains from the early Oligoc…
