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…

Jin, W.-T., Gernandt, D. S., Wehenkel, C., Xia, X.-M., Wei, X.-X., & Wang, X.-Q. (2021). Phylogenomic and ecological analyses reveal the spatiotemporal evolution of global pines. Proceedings of the National Academy of Sciences, 118(20), e2022302118. doi:10.1073/pnas.2022302118 https://doi.org/10.1073/pnas.2022302118

How coniferous forests evolved in the Northern Hemisphere remains largely unknown. Unlike most groups of organisms that generally follow a latitudinal diversity gradient, most conifer species in the Northern Hemisphere are distributed in mountainous areas at middle latitudes. It is of great interest…

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…

DeLaMater, D. S., Couture, J. J., Puzey, J. R., & Dalgleish, H. J. (2021). Range‐wide variations in common milkweed traits and their effect on monarch larvae. American Journal of Botany, 108(3), 388–401. doi:10.1002/ajb2.1630 https://doi.org/10.1002/ajb2.1630

Premise: Leaf economic spectrum (LES) theory has historically been employed to inform vegetation models of ecosystem processes, but largely neglects intraspecific variation and biotic interactions. We attempt to integrate across environment–plant trait–herbivore interactions within a species at a ra…

Briscoe Runquist, R. D., Lake, T. A., & Moeller, D. A. (2021). Improving predictions of range expansion for invasive species using joint species distribution models and surrogate co‐occurring species. Journal of Biogeography. doi:10.1111/jbi.14105 https://doi.org/10.1111/jbi.14105

Aims: Species distribution models (SDMs) are often used to forecast potential distributions of important invasive or rare species. However, situations where models could be the most valuable ecologically or economically, such as for predicting invasion risk, often pose the greatest challenges to SDM…

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…

Follak, S., Bakacsy, L., Essl, F., Hochfellner, L., Lapin, K., Schwarz, M., … Wołkowycki, D. (2021). Monograph of invasive plants in Europe N°6: Asclepias syriaca L. Botany Letters, 1–30. doi:10.1080/23818107.2021.1886984 https://doi.org/10.1080/23818107.2021.1886984

This work synthesizes all aspects of Asclepias syriaca L. (Apocynaceae) including the taxonomy, distribution, history of introduction and spread, ecology, biology, uses and benefits, impacts on biodiversity and agriculture, legislation, and management. Asclepias syriaca is a perennial broad-leaved s…

Géron, C., Lembrechts, J. J., Borgelt, J., Lenoir, J., Hamdi, R., Mahy, G., … Monty, A. (2021). Urban alien plants in temperate oceanic regions of Europe originate from warmer native ranges. Biological Invasions. doi:10.1007/s10530-021-02469-9 https://doi.org/10.1007/s10530-021-02469-9

When colonizing new areas, alien plant species success can depend strongly on local environmental conditions. Microclimatic barriers might be the reason why some alien plant species thrive in urban areas, while others prefer rural environments. We tested the hypothesis that the climate in the native…

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…
