Ruiz, D. P., Pujana, R. R., & Brea, M. (2021). Early Miocene paleoclimate in southern Patagonia inferred from fossil woods. Review of Palaeobotany and Palynology, 290, 104429. doi:10.1016/j.revpalbo.2021.104429 https://doi.org/10.1016/j.revpalbo.2021.104429

Patagonia has a rich record of fossil woods that are a unique data store of paleoclimatic information. We studied the wood flora recovered from the Río Leona Formation (early Miocene) of southern Patagonia near El Calafate and Río Turbio localities, Santa Cruz Province, Argentina. The fossil wood as…

Rock, B. M., & Daru, B. H. (2021). Impediments to Understanding Seagrasses’ Response to Global Change. Frontiers in Marine Science, 8. doi:10.3389/fmars.2021.608867 https://doi.org/10.3389/fmars.2021.608867

Uncertainties from sampling biases present challenges to ecologists and evolutionary biologists in understanding species sensitivity to anthropogenic climate change. Here, we synthesize possible impediments that can constrain research to assess present and future seagrass response from climate chang…

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…

Hambuckers, A., de Harenne, S., Rocha Ledezma, E., Zúñiga Zeballos, L., & François, L. (2021). Predicting the Future Distribution of Ara rubrogenys, an Endemic Endangered Bird Species of the Andes, Taking into Account Trophic Interactions. Diversity, 13(2), 94. doi:10.3390/d13020094 https://doi.org/10.3390/d13020094

Species distribution models (SDMs) are commonly used with climate only to predict animal distribution changes. This approach however neglects the evolution of other components of the niche, like food resource availability. SDMs are also commonly used with plants. This also suffers limitations, notab…

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…

Shaw, E. C., Fowler, R., Ohadi, S., Bayly, M. J., Barrett, R. A., Tibbits, J., … Cousens, R. D. (2020). Explaining the worldwide distributions of two highly mobile species: Cakile edentula and Cakile maritima. Journal of Biogeography. doi:10.1111/jbi.14024 https://doi.org/10.1111/jbi.14024

Aim: If we are able to determine the geographic origin of an invasion, as well as its known area of introduction, we can better appreciate the innate environmental tolerance of a species and the strength of selection for adaptation that colonizing populations have undergone. It also enables us to ma…

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…

Ebersbach, J., Tkach, N., Röser, M., & Favre, A. (2020). The Role of Hybridisation in the Making of the Species-Rich Arctic-Alpine Genus Saxifraga (Saxifragaceae). Diversity, 12(11), 440. doi:10.3390/d12110440 https://doi.org/10.3390/d12110440

Evolutionary processes fuelling rapid species diversification are not yet fully understood, although their major contribution to overall patterns of plant biodiversity is well established. Hybridisation is among the least understood of these processes, despite its multifaceted role in speciation pro…

Zanatta, F., Engler, R., Collart, F., Broennimann, O., Mateo, R. G., Papp, B., … Vanderpoorten, A. (2020). Bryophytes are predicted to lag behind future climate change despite their high dispersal capacities. Nature Communications, 11(1). doi:10.1038/s41467-020-19410-8 https://doi.org/10.1038/s41467-020-19410-8

The extent to which species can balance out the loss of suitable habitats due to climate warming by shifting their ranges is an area of controversy. Here, we assess whether highly efficient wind-dispersed organisms like bryophytes can keep-up with projected shifts in their areas of suitable climate.…
