Bontrager, M., Usui, T., Lee‐Yaw, J. A., Anstett, D. N., Branch, H. A., Hargreaves, A. L., … Angert, A. L. (2021). Adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion. Evolution. doi:10.1111/evo.14231 https://doi.org/10.1111/evo.14231

Every species experiences limits to its geographic distribution. Some evolutionary models predict that populations at range edges are less well‐adapted to their local environments due to drift, expansion load, or swamping gene flow from the range interior. Alternatively, populations near range edges…

Mazijk, R., Cramer, M. D., & Verboom, G. A. (2021). Environmental heterogeneity explains contrasting plant species richness between the South African Cape and southwestern Australia. Journal of Biogeography. doi:10.1111/jbi.14118 https://doi.org/10.1111/jbi.14118

Aim: Given the importance of environmental heterogeneity as a driver of species richness through its effects on species diversification and coexistence, we asked whether the dramatic difference in species richness per unit area between two similar Mediterranean‐type biodiversity hotspots is explaine…

Banerjee, A. K., Wu, H., Guo, W., Ng, W. L., Li, W., Ma, Y., … Huang, Y. (2021). Deciphering the global phylogeography of a coastal shrub ( Scaevola taccada ) reveals the influence of multiple forces on contemporary population structure. Journal of Systematics and Evolution. doi:10.1111/jse.12746 https://doi.org/10.1111/jse.12746

The phylogeography of coastal plant species is heavily influenced by past sea‐level fluctuations, dispersal barriers, and life‐history traits, such as long‐distance dispersal ability of the propagules. Unlike the widely studied mangroves, phylogeographic patterns have remained mostly obscure for oth…

Allstädt, F. J., Koutsodendris, A., Appel, E., Rösler, W., Reichgelt, T., Kaboth-Bahr, S., … Pross, J. (2021). Late Pliocene to early Pleistocene climate dynamics in western North America based on a new pollen record from paleo-Lake Idaho. Palaeobiodiversity and Palaeoenvironments. doi:10.1007/s12549-020-00460-1 https://doi.org/10.1007/s12549-020-00460-1

Marked by the expansion of ice sheets in the high latitudes, the intensification of Northern Hemisphere glaciation across the Plio/Pleistocene transition at ~ 2.7 Ma represents a critical interval of late Neogene climate evolution. To date, the characteristics of climate change in North America duri…

Brendel, M. R., Schurr, F. M., & Sheppard, C. S. (2020). Inter‐ and intraspecific selection in alien plants: How population growth, functional traits and climate responses change with residence time. Global Ecology and Biogeography. doi:10.1111/geb.13228 https://doi.org/10.1111/geb.13228

Aim: When alien species are introduced to new ranges, climate or trait mismatches may initially constrain their population growth. However, inter‐ and intraspecific selection in the new environment should cause population growth rates to increase with residence time. Using a species‐for‐time approac…

Deanna, R., Wilf, P., & Gandolfo, M. A. (2020). New physaloid fruit‐fossil species from early Eocene South America. American Journal of Botany, 107(12), 1749–1762. doi:10.1002/ajb2.1565 https://doi.org/10.1002/ajb2.1565

Premise: Solanaceae is a scientifically and economically important angiosperm family with a minimal fossil record and an intriguing early evolutionary history. Here, we report a newly discovered fossil lantern fruit with a suite of features characteristic of Physalideae within Solanaceae. The fossil…

Iqbal, I., Shabbir, A., Shabbir, K., Barkworth, M., Bareen, F., & Khan, S. (2020). Evolvulus nummularius (L.) L. (Convolvulaceae): a new alien plant record for Pakistan. BioInvasions Records, 9(4), 702–711. doi:10.3391/bir.2020.9.4.04 https://doi.org/10.3391/bir.2020.9.4.04

Evolvulus nummularius (L.) L., a member of the Convolvulaceae, is native to Mexico and South America but nowadays grows around the world in many tropical and subtropical regions. Its presence in Pakistan, where it has become naturalized, is reported here for the first time. It was first discovered i…

Del Rio, C., Huang, J., Liu, P., Deng, W., Spicer, T. E. V., Wu, F., … Su, T. (2020). New Eocene fossil fruits and leaves of Menispermaceae from the central Tibetan Plateau and their biogeographic implications. Journal of Systematics and Evolution. doi:10.1111/jse.12701 https://doi.org/10.1111/jse.12701

Menispermaceae are a pantropical and temperate family with an extensive fossil record during the Paleogene, especially in North America and Europe, but with much less evidence from Asia. The latest fossil evidence indicates a succession of tropical to sub‐tropical flora on the central Tibetan Platea…

Yi, S., Jun, C.-P., Jo, K., Lee, H., Kim, M.-S., Lee, S. D., … Lim, J. (2020). Asynchronous multi-decadal time-scale series of biotic and abiotic responses to precipitation during the last 1300 years. Scientific Reports, 10(1). doi:10.1038/s41598-020-74994-x https://doi.org/10.1038/s41598-020-74994-x
