Stone, B. W., & Wolfe, A. D. (2021). Phylogeographic analysis of shrubby beardtongues reveals range expansions during the Last Glacial Maximum and implicates the Klamath Mountains as a hotspot for hybridization. Molecular Ecology. doi:10.1111/mec.15992 https://doi.org/10.1111/mec.15992

Quaternary glacial cycles often altered species' geographic distributions, which in turn altered the geographic structure of species' genetic diversity. In many cases, glacial expansion forced species in temperate climates to contract their ranges and reside in small pockets of suitable habitat (ref…

Kriticos, D. J., Ireland, K. B., Morin, L., Kumaran, N., Rafter, M. A., Ota, N., & Raghu, S. (2021). Integrating ecoclimatic niche modelling methods into classical biological control programmes. Biological Control, 160, 104667. doi:10.1016/j.biocontrol.2021.104667 https://doi.org/10.1016/j.biocontrol.2021.104667

Much of the success of a classical biological control programme hinges on identifying effective candidate agents, and once approved for release deploying them in the range invaded by the target organism at site-specific times of the year when they have the best chance of establishing. While suitable…

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…

Hermsen, E. J. (2021). Review of the fossil record of Passiflora, with a description of new seeds from the Pliocene Gray Fossil Site, Tennessee, U.S.A. International Journal of Plant Sciences. doi:10.1086/714282 https://doi.org/10.1086/714282

Premise of the research. Passifloroideae (over 700 species), which include the large genus Passiflora (over 550 species), are distributed pantropically today. The fossil record of the group is, nevertheless, small and poorly understood. In this study, I provide a critical review of the fossil record…

Saldaña‐López, A., Vilà, M., Lloret, F., Manuel Herrera, J., & González‐Moreno, P. (2021). Assembly of species’ climatic niches of coastal communities does not shift after invasion. Journal of Vegetation Science, 32(2). doi:10.1111/jvs.12989 https://doi.org/10.1111/jvs.12989

Question: Do invasions by invasive plant species with contrasting trait profiles (Arctotheca calendula, Carpobrotus spp., Conyza bonariensis, and Opuntia dillenii) change the climatic niche of coastal plant communities? Location: Atlantic coastal habitats in Huelva (Spain). Methods: We identifi…

Mertens, A., Swennen, R., Rønsted, N., Vandelook, F., Panis, B., Sachter‐Smith, G., … Janssens, S. B. (2021). Conservation status assessment of banana crop wild relatives using species distribution modelling. Diversity and Distributions. doi:10.1111/ddi.13233 https://doi.org/10.1111/ddi.13233

Aim: Crop wild relatives (CWR) are an essential source of genetic material for the improvement of certain traits in related crop species. Despite their importance, increasing public, scientific and political support, large gaps exist in the amount of genetic material collected and conserved of many…

Akin-Fajiye, M., & Akomolafe, G. F. (2021). Disturbance is an important predictor of the distribution of Lantana camara and Chromolaena odorata in Africa. Vegetos. doi:10.1007/s42535-020-00179-6 https://doi.org/10.1007/s42535-020-00179-6

Most studies of invasion have used climatic variables without considering the importance of disturbance on the distribution of the species. In this study, MAXENT was used to model how disturbance, in addition to climatic factors, can affect the invasion of two of the most problematic plant invaders …

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…

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…
