Stropp, J., Umbelino, B., Correia, R. A., Campos-Silva, J. V., Ladle, R. J., & Malhado, A. C. M. (2020). The ghosts of forests past and future: deforestation and botanical sampling in the Brazilian Amazon. Ecography. doi:10.1111/ecog.05026 https://doi.org/10.1111/ecog.05026

The remarkable biodiversity of the Brazilian Amazon is poorly documented and threatened by deforestation. When undocumented areas become deforested, in addition to losing the fauna and flora, we lose the opportunity to know which unique species had occupied a habitat. Here we quantify such knowledge…

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…

Ruiz-Sanchez, E., Munguía-Lino, G., Vargas-Amado, G., & Rodríguez, A. (2019). Diversity, endemism and conservation status of native Mexican woody bamboos (Poaceae: Bambusoideae: Bambuseae). Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boz062 https://doi.org/10.1093/botlinnean/boz062

Native Mexican woody bamboos (Poaceae: Bambusoideae: Bambuseae) are classified in subtribes Arthrostylidiinae, Chusqueinae and Guaduinae. They grow from sea level up to 3200 m along the main mountain ranges and occupy different vegetation types. The aims of this study were to: identify the areas wit…

Rodríguez-Merino, A., Fernández-Zamudio, R., García-Murillo, P., & Muñoz, J. (2019). Climatic Niche Shift during Azolla filiculoides Invasion and Its Potential Distribution under Future Scenarios. Plants, 8(10), 424. doi:10.3390/plants8100424 https://doi.org/10.3390/plants8100424

In order to prevent future biological invasions, it is crucial to know non-native species distributions. We evaluated the potential global distribution of Azolla filiculoides, a free-floating macrophyte native to the Americas by using species distribution models and niche equivalency tests to analyz…

Marconi, L., & Armengot, L. (2020). Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment, 287, 106664. doi:10.1016/j.agee.2019.106664 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.…

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. …

Margaroni, S., Petersen, K. B., Gleadow, R., & Burd, M. (2019). The role of spore size in the global pattern of co-occurrence among Selaginella species. Journal of Biogeography. doi:10.1111/jbi.13532 https://doi.org/10.1111/jbi.13532

Aim: Separation of regeneration niches may promote coexistence among closely related plant species, but there is little evidence that regeneration traits affect species ranges at broad geographical scales. We address patterns of co‐occurrence within the genus Selaginella, an ancient lineage of free‐…

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…

Peterson, A. T., Asase, A., Canhos, D., de Souza, S., & Wieczorek, J. (2018). Data Leakage and Loss in Biodiversity Informatics. Biodiversity Data Journal, 6. doi:10.3897/bdj.6.e26826 https://doi.org/10.3897/bdj.6.e26826

The field of biodiversity informatics is in a massive, “grow-out” phase of creating and enabling large-scale biodiversity data resources. Because perhaps 90% of existing biodiversity data nonetheless remains unavailable for science and policy applications, the question arises as to how these existin…

Crespo-Mendes, N., Laurent, A., & Hauschild, M. Z. (2018). Effect factors of terrestrial acidification in Brazil for use in Life Cycle Impact Assessment. The International Journal of Life Cycle Assessment. doi:10.1007/s11367-018-1560-7 https://doi.org/10.1007/s11367-018-1560-7

Purpose:In Life Cycle Impact Assessment, atmospheric fate factors, soil exposure factors, and effect factors are combined to characterize potential impacts of acidifying substances in terrestrial environments. Due to the low availability of global data sets, effect factors (EFs) have been reported a…
