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…

Magri, D., Parra, I., Di Rita, F., Ni, J., Shichi, K., & Worth, J. R. P. (2020). Linking worldwide past and present conifer vulnerability. Quaternary Science Reviews, 250, 106640. doi:10.1016/j.quascirev.2020.106640 https://doi.org/10.1016/j.quascirev.2020.106640

Inventories of species recently extinct or threatened with extinction may be found in global databases. However, despite the large number of published fossil based-studies, specific databases on the vulnerability of species in the past are not available. We compiled a worldwide database of published…

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…

Rozefelds, A. C., Stull, G., Hayes, P., & Greenwood, D. R. (2020). The fossil record of Icacinaceae in Australia supports long-standing Palaeo-Antarctic rainforest connections in southern high latitudes. Historical Biology, 1–11. doi:10.1080/08912963.2020.1832089 https://doi.org/10.1080/08912963.2020.1832089

Fossil fruits of Icacinaceae are recorded from two Cenozoic sites in Australia, at Launceston in northern Tasmania and the Poole Creek palaeochannel in northern South Australia, representing the first report of fossil Icacinaceae from Australia. The Launceston material includes two endocarps with br…

Lv, Z., Liu, F., Zhang, Y., Tu, Y., Chen, P., & Peng, L. (2020). Ecologically adaptable Populus simonii is specific for recalcitrance‐reduced lignocellulose and largely‐enhanced enzymatic saccharification among woody plants. GCB Bioenergy. doi:10.1111/gcbb.12764 https://doi.org/10.1111/gcbb.12764

Woody plants provide enormous biomass resource convertible for biofuels and bioproducts, but they are of typical lignified secondary cell walls with strong recalcitrance against biomass degradation. It thus becomes critical to find out the desirable woody plant enabled for efficient biomass enzymati…

Larridon, I., Galán Díaz, J., Bauters, K., & Escudero, M. (2020). What drives diversification in a pantropical plant lineage with extraordinary capacity for long‐distance dispersal and colonization? Journal of Biogeography. doi:10.1111/jbi.13982 https://doi.org/10.1111/jbi.13982

Aim: Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesti…

Chevalier, M., Chase, B. M., Quick, L. J., Dupont, L. M., & Johnson, T. C. (2020). Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology. doi:10.1130/g47841.1 https://doi.org/10.1130/G47841.1

Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…

Tan, K., Lu, T., & Ren, M.-X. (2020). Biogeography and evolution of Asian Gesneriaceae based on updated taxonomy. PhytoKeys, 157, 7–26. doi:10.3897/phytokeys.157.34032 https://doi.org/10.3897/phytokeys.157.34032

Based on an updated taxonomy of Gesneriaceae, the biogeography and evolution of the Asian Gesneriaceae are outlined and discussed. Most of the Asian Gesneriaceae belongs to Didymocarpoideae, except Titanotrichum was recently moved into Gesnerioideae. Most basal taxa of the Asian Gesneriaceae are fou…

Zhernova, D. A., Nilova, M. V., & Oskolski, A. A. (2020). Comparative wood anatomy of Astropanax and Neocussonia, an Afro-Malagasy lineage of Araliaceae. Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boaa067 https://doi.org/10.1093/botlinnean/boaa067

Astropanax and Neocussonia are two recently resurrected genera of Araliaceae that had long been considered as an Afro-Malagasy lineage of Schefflera. The wood structure of 11 Neocussonia spp. and eight Astropanax spp. has been studied. Neocussonia shows a higher average length of vessel elements (13…
