De La Pascua, D. R., Smith‐Winterscheidt, C., Dowell, J. A., Goolsby, E. W., & Mason, C. M. (2020). Evolutionary trade‐offs in the chemical defense of floral and fruit tissues across genus Cornus. American Journal of Botany, 107(9), 1260–1273. doi:10.1002/ajb2.1540 https://doi.org/10.1002/ajb2.1540

Premise: Defense investment in plant reproductive structures is relatively understudied compared to the defense of vegetative organs. Here the evolution of chemical defenses in reproductive structures is examined in light of the optimal defense, apparency, and resource availability hypotheses within…

Myrans, H., Diaz, M. V., Khoury, C. K., Carver, D., Henry, R. J., & Gleadow, R. (2020). Modelled distributions and conservation priorities of wild sorghums ( Sorghum Moench). Diversity and Distributions, 26(12), 1727–1740. doi:10.1111/ddi.13166 https://doi.org/10.1111/ddi.13166

Aim: To fill knowledge gaps regarding the distributions, ecogeographic niches and conservation status of sorghum's wild relatives (Sorghum Moench). Location: The study covered the potential native ranges of wild Sorghum taxa worldwide, including Australia, New Guinea, Asia, Africa and Central Ameri…

Bitani, N., Ehlers Smith, D. A., Ehlers Smith, Y. C., & Downs, C. T. (2020). Functional traits vary among fleshy-fruited invasive plant species and their potential avian dispersers. Acta Oecologica, 108, 103651. doi:10.1016/j.actao.2020.103651 https://doi.org/10.1016/j.actao.2020.103651

Habitat fragmentation has a multitude of negative effects on biodiversity, including the facilitation of alien plant invasion. Of concern in South Africa is the spread of fleshy-fruited invasive plant species, which in many places are replacing indigenous vegetation in frequently disturbed and fragm…

Cross, A. T., Krueger, T. A., Gonella, P. M., Robinson, A. S., & Fleischmann, A. S. (2020). Conservation of carnivorous plants in the age of extinction. Global Ecology and Conservation, e01272. doi:10.1016/j.gecco.2020.e01272 https://doi.org/10.1016/j.gecco.2020.e01272

Carnivorous plants (CPs)—those possessing specific strategies to attract, capture and kill animal prey and obtain nutrition through the absorption of their biomass—are harbingers of anthropogenic degradation and destruction of ecosystems. CPs exhibit highly specialised and often very sensitive ecolo…

Kolanowska, M., Rewicz, A., & Baranow, P. (2020). Ecological niche modeling of the pantropical orchid Polystachya concreta (Orchidaceae) and its response to climate change. Scientific Reports, 10(1). doi:10.1038/s41598-020-71732-1 https://doi.org/10.1038/s41598-020-71732-1

Climate is the dominant control factor on the spatial distribution of organisms on a global scale and global warming is predicted to become a major cause of species extinctions. In our study ecological niche modeling (ENM) was used to estimate the effect of projected future climate changes on the pa…

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…

Lindelof, K., Lindo, J. A., Zhou, W., Ji, X., & Xiang, Q. (Jenny). (2020). Phylogenomics, biogeography, and evolution of the blue‐ or white‐fruited dogwoods ( Cornus ) ‐ insights into morphological and ecological niche divergence following intercontinental geographic isolation. Journal of Systematics and Evolution. doi:10.1111/jse.12676 https://doi.org/10.1111/jse.12676

The eastern Asian (EA)–eastern North American (ENA) floristic disjunction represents a major pattern of phytogeography of the Northern Hemisphere. Despite 20 years of studies dedicated to identification of taxa that display this disjunct pattern, its origin and evolution remain an open question, esp…

De Jesús Hernández-Hernández, M., Cruz, J. A., & Castañeda-Posadas, C. (2020). Paleoclimatic and vegetation reconstruction of the miocene southern Mexico using fossil flowers. Journal of South American Earth Sciences, 104, 102827. doi:10.1016/j.jsames.2020.102827 https://doi.org/10.1016/j.jsames.2020.102827

Concern about the course of the current environmental problems has raised interest in investigating the different scenarios that have taken place in our planet throughout time. To that end, different methodologies have been employed in order to determine the different variables that compose the envi…

Clark, M. D., Wonkka, C. L., Kreuter, U. P., & Rogers, W. E. (2020). Interactive effects of prescribed fire and livestock grazing on Seriphium plumosum in South African sour bushveld. African Journal of Range & Forage Science, 1–8. doi:10.2989/10220119.2020.1751287 https://doi.org/10.2989/10220119.2020.1751287

Documented increases in woody plant abundance worldwide can reduce land value and grazing capacity. Throughout many grasslands and savannas in South Africa, Seriphium plumosum, an encroaching woody plant, has been rapidly displacing desirable native species. Cost-effective management techniques are …
