Zhang, N., Liao, Z., Wu, S., Nobis, M. P., Wang, J., & Wu, N. (2021). Impact of climate change on wheat security through an alternate host of stripe rust. Food and Energy Security. doi:10.1002/fes3.356 https://doi.org/10.1002/fes3.356

In the 21st century, stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is still the most devastating disease of wheat globally. Despite the critical roles of the alternate host plants, the Berberis species, in the sexual reproduction and spread of Pst, the climate change impacts on t…

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…

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…

Banerjee, A. K., Feng, H., Lin, Y., Hou, Z., Li, W., Shao, H., … Huang, Y. (2021). Phylogeographic pattern of a cryptoviviparous mangrove, Aegiceras corniculatum, in the Indo-West Pacific, provides insights for conservation actions. Planta, 255(1). doi:10.1007/s00425-021-03798-8 https://doi.org/10.1007/s00425-021-03798-8

Phylogeographic studies are used to understand the spatial distribution and evolution of genetic diversity, and have major conservation implications, especially for threatened taxa like the mangroves. This study aimed to assess the phylogeographic pattern of Aegiceras corniculatum, a cryptoviviparou…

Kolanowska, M. (2021). The future of a montane orchid species and the impact of climate change on the distribution of its pollinators and magnet species. Global Ecology and Conservation, 32, e01939. doi:10.1016/j.gecco.2021.e01939 https://doi.org/10.1016/j.gecco.2021.e01939

The aim of this study was to evaluate the impact of global warming on suitable niches of montane orchid, Traunsteinera globosa, using ecological niche modelling approach. Additionally, the effect of various climate change scenarios on future changes in the distribution and overlap of the orchid magn…

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…

Benhadi-Marín, J., Fereres, A., & Pereira, J. A. (2021). Potential areas of spread of Trioza erytreae over mainland Portugal and Spain. Journal of Pest Science. doi:10.1007/s10340-021-01440-w https://doi.org/10.1007/s10340-021-01440-w

Trioza erytreae is one natural psyllid vector of Candidatus liberibacter, the causal agent of the citrus greening disease (HLB). Since its introduction in 2014 into the Iberian Peninsula, T. erytreae was able to spread continuously toward southern coastal regions of Portugal and northern coastal reg…
