Giliba, R. A., & Yengoh, G. T. (2020). Predicting Suitable Habitats of the African Cherry (Prunus africana) under Climate Change in Tanzania. Atmosphere, 11(9), 988. doi:10.3390/atmos11090988 https://doi.org/10.3390/atmos11090988

Prunus africana is a fast-growing, evergreen canopy tree with several medicinal, household, and agroforestry uses, as well as ecological value for over 22 countries in sub-Saharan Africa. This species is under immense pressure from human activity, compounding its vulnerability to the effects of clim…

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…

Fazlioglu, F., Wan, J. S. H., & Chen, L. (2020). Latitudinal shifts in mangrove species worldwide: evidence from historical occurrence records. Hydrobiologia. doi:10.1007/s10750-020-04403-x https://doi.org/10.1007/s10750-020-04403-x

Consequences of global climate change on mangrove habitats are ambiguous owing to multifaceted factors. In this study, we examined historical occurrences of ten common mangrove species and quantified the rate of latitudinal shift as a possible response to climate change. The Global Biodiversity Info…

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…

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…

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…

Frankiewicz, K. E., Chau, J. H., & Oskolski, A. A. (2020). Wood and bark of Buddleja: uniseriate phellem, and systematic and ecological patterns. IAWA Journal, 1–40. doi:10.1163/22941932-bja10020 https://doi.org/10.1163/22941932-bja10020

Wood anatomy of Buddleja is well-explored but not in many southern African members, which form a grade of species and small clades that form successive sister groups to the rest of the genus, and its bark structure has not been studied at all. We provide new descriptions of wood anatomy for twelve s…

Piepenbring, M., Maciá-Vicente, J. G., Codjia, J. E. I., Glatthorn, C., Kirk, P., Meswaet, Y., … Yorou, N. S. (2020). Mapping mycological ignorance – checklists and diversity patterns of fungi known for West Africa. IMA Fungus, 11(1). doi:10.1186/s43008-020-00034-y https://doi.org/10.1186/s43008-020-00034-y

Scientific information about biodiversity distribution is indispensable for nature conservation and sustainable management of natural resources. For several groups of animals and plants, such data are available, but for fungi, especially in tropical regions like West Africa, they are mostly missing.…
