De Deus Vidal, J., le Roux, P. C., Johnson, S. D., te Beest, M., & Clark, V. R. (2021). Beyond the Tree-Line: The C3-C4 “Grass-Line” Can Track Global Change in the World’s Grassy Mountain Systems. Frontiers in Ecology and Evolution, 9. doi:10.3389/fevo.2021.760118 https://doi.org/10.3389/fevo.2021.760118

von Humboldt’s tree-line concept has dominated mountain ecology for almost two hundred years, and is considered a key indicator for monitoring change in biome boundaries and biodiversity shifts under climate change. Even though the concept of life zones and elevation gradients are a globally observe…

Lim, J. Y., Huang, H., Farnsworth, A., Lunt, D. J., Baker, W. J., Morley, R. J., … Jordan, G. (2021). The Cenozoic history of palms: Global diversification, biogeography and the decline of megathermal forests. Global Ecology and Biogeography. doi:10.1111/geb.13436 https://doi.org/10.1111/geb.13436

Aim: Megathermal rain forests and mangroves are much smaller in extent today than in the early Cenozoic, primarily owing to global cooling and drying trends since the Eocene–Oligocene transition (c. 34 Ma). The general reduction of these biomes is hypothesized to shape the diversity and biogeographi…

Beaulieu, W. T., Panaccione, D. G., Quach, Q. N., Smoot, K. L., & Clay, K. (2021). Diversification of ergot alkaloids and heritable fungal symbionts in morning glories. Communications Biology, 4(1). doi:10.1038/s42003-021-02870-z https://doi.org/10.1038/s42003-021-02870-z

Heritable microorganisms play critical roles in life cycles of many macro-organisms but their prevalence and functional roles are unknown for most plants. Bioactive ergot alkaloids produced by heritable Periglandula fungi occur in some morning glories (Convolvulaceae), similar to ergot alkaloids in …

Vasconcelos, T., Boyko, J. D., & Beaulieu, J. M. (2021). Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. doi:10.1111/jbi.14292 https://doi.org/10.1111/jbi.14292

Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…

Roberts, J., & Florentine, S. (2021). A review of the biology, distribution patterns and management of the invasive species Amaranthus palmeri S. Watson (Palmer amaranth): Current and future management challenges. Weed Research. doi:10.1111/wre.12520 https://doi.org/10.1111/wre.12520

Amaranthus palmeri S. Watson (Palmer amaranth) is an invasive agricultural weed that has quickly risen from a state of relative obscurity to now being globally regarded as one of the most economically destructive and difficult to manage weed species. It is now found in more than 45 countries where i…

Alban, D. M., Biersma, E. M., Kadereit, J. W., & Dillenberger, M. S. (2021). Colonization of the Southern Hemisphere by Sagina and Colobanthus (Caryophyllaceae). Plant Systematics and Evolution, 308(1). doi:10.1007/s00606-021-01793-w https://doi.org/10.1007/s00606-021-01793-w

Colobanthus (23 species) and Sagina (30–33 species) together are sister to Facchinia. Whereas Facchinia is distributed in western Eurasia, Colobanthus is almost exclusively distributed in the Southern Hemisphere, and Sagina is distributed in both hemispheres with the highest species diversity in wes…

Moshobane, M. C., Mudereri, B. T., Mukundamago, M., & Chitata, T. (2022). Predicting future distribution patterns of Jatropha gossypiifolia L. in South Africa in response to climate change. South African Journal of Botany, 146, 417–425. doi:10.1016/j.sajb.2021.11.031 https://doi.org/10.1016/j.sajb.2021.11.031

Invasive alien species such as Bellyache bush (Jatropha gossypiifolia L.) pose immense threats to global food security, biodiversity, ecosystem integrity and provision of ecosystem services. The Bellyache bush has generally been naturalised in Africa but poses vast management challenges in the Afric…

Cahen, D., Rickenback, J., & Utteridge, T. M. A. (2021). A revision of Ziziphus (Rhamnaceae) in Borneo. Kew Bulletin. doi:10.1007/s12225-021-09970-3 https://doi.org/10.1007/s12225-021-09970-3

The genus Ziziphus (Rhamnaceae) is revised for Borneo. 13 species are recognised using morphological evidence, including three new endemic species: Ziziphus cuspidata, Z. domatiata and Z. puberula. Borneo is therefore the island with the greatest known diversity of Ziziphus species. The area surroun…

Xue, T., Gadagkar, S. R., Albright, T. P., Yang, X., Li, J., Xia, C., … Yu, S. (2021). Prioritizing conservation of biodiversity in an alpine region: Distribution pattern and conservation status of seed plants in the Qinghai-Tibetan Plateau. Global Ecology and Conservation, 32, e01885. doi:10.1016/j.gecco.2021.e01885 https://doi.org/10.1016/j.gecco.2021.e01885

The Qinghai-Tibetan Plateau (QTP) harbors abundant and diverse plant life owing to its high habitat heterogeneity. However, the distribution pattern of biodiversity hotspots and their conservation status remain unclear. Based on 148,283 high-resolution occurrence coordinates of 13,450 seed plants, w…

López‐Delgado, J., & Meirmans, P. G. (2021). History or demography? Determining the drivers of genetic variation in North American plants. Molecular Ecology. doi:10.1111/mec.16230 https://doi.org/10.1111/mec.16230

Understanding the impact of historical and demographic processes on genetic variation is essential for devising conservation strategies and predicting responses to climate change. Recolonization after Pleistocene glaciations is expected to leave distinct genetic signatures, characterised by lower ge…
