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. …

Gomes, S. I. F., P. M. van Bodegom, V. S. F. T. Merckx, and N. A. Soudzilovskaia. 2019. Global distribution patterns of mycoheterotrophy G. Jordan [ed.],. Global Ecology and Biogeography 28: 1133–1145. https://doi.org/10.1111/geb.12920

Aim: Mycoheterotrophy is a mode of life where plants cheat the mycorrhizal symbiosis, receiving carbon via their fungal partners. Despite being widespread, mycoheterotrophic plants are locally rare, hampering the understanding of their global environmental drivers. Here, we explore global environmen…

Gamisch, A., and H. P. Comes. 2019. Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae). BMC Evolutionary Biology 19. https://doi.org/10.1186/s12862-019-1416-1

Background: Tropical rainforests (TRFs) harbour almost half of the world’s vascular plant species diversity while covering only about 6–7% of land. However, why species richness varies amongst the Earth’s major TRF regions remains poorly understood. Here we investigate the evolutionary processes sha…

Margaroni, S., K. B. Petersen, R. Gleadow, and M. Burd. 2019. The role of spore size in the global pattern of co‐occurrence among Selaginella species. Journal of Biogeography 46: 807–815. 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., M. Kessler, O. Conrad, P. Weigelt, H. Kreft, C. König, and N. E. Zimmermann. 2019. Why tree lines are lower on islands—Climatic and biogeographic effects hold the answer J. Grytnes [ed.],. Global Ecology and Biogeography 28: 839–850. 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…

Chevalier, M. 2019. Enabling possibilities to quantify past climate from fossil assemblages at a global scale. Global and Planetary Change 175: 27–35. https://doi.org/10.1016/j.gloplacha.2019.01.016

The field of quantitative palaeoclimatology has made significant progress in the past decades. However, this progress has been spatially heterogeneous and strong discrepancies – both in terms of quality and density – exist between Europe and North America and the rest of the world. The need to balan…

Xie, S.-P., S.-H. Zhang, T.-Y. Chen, X.-C. Zhang, X. Zeng, and Y. Yu. 2018. Late Miocene occurrence of monogeneric family Oleandraceae from southwest China and its implications on evolution of eupolypods I. Review of Palaeobotany and Palynology 256: 13–19. https://doi.org/10.1016/j.revpalbo.2018.05.002

Yunnan in SW China is a world renowned hotspot for diverse species of vascular plants such as ferns. However, fossil records of the Cenozoic ferns there are insufficient to clarify their phylogeny and historical biogeography from a geological perspective. Among these derived ferns, the monogeneric f…

Petersen, K. B., and M. Burd. 2018. The adaptive value of heterospory: Evidence from Selaginella. Evolution 72: 1080–1091. https://doi.org/10.1111/evo.13484

Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. We used the geographic distributions of 114 species of the heterosporous lycophyte Selaginella to explore the functional ecology of microspore and megaspore size, traits that would be corre…

Caudullo, G., E. Welk, and J. San-Miguel-Ayanz. 2017. Chorological maps for the main European woody species. Data in Brief 12: 662–666. https://doi.org/10.1016/j.dib.2017.05.007

A novel chorological data compilation for the main European tree and shrub species is presented. This dataset was produced by combining numerous and heterogeneous data collected from 20th century atlas monographs providing complete species distribution maps, and from more recent national to regional…
