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…

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…

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…

Whitman, M., Beaman, R. S., Repin, R., Kitayama, K., Aiba, S., & Russo, S. E. (2021). Edaphic specialization and vegetation zones define elevational range‐sizes for Mt Kinabalu regional flora. Ecography. doi:10.1111/ecog.05873 https://doi.org/10.1111/ecog.05873

Identifying physical and ecological boundaries that limit where species can occur is important for predicting how those species will respond to global change. The island of Borneo encompasses a wide range of habitats that support some of the highest richness on Earth, making it an ideal location for…

Chu, X., Gugger, P. F., Li, L., Zhao, J., & Li, Q. (2021). Responses of an endemic species ( Roscoea humeana ) in the Hengduan Mountains to climate change. Diversity and Distributions. doi:10.1111/ddi.13397 https://doi.org/10.1111/ddi.13397

Aim: Adaptation, migration and extinction of species is closely associated with climate changes and shape the distribution of biodiversity. The adaptive responses of species in the biodiversity hotspot, the Hengduan Mountains, to climate change remain poorly understood. Location: The Hengduan Mount…

Deanna, R., Wilf, P., & Gandolfo, M. A. (2020). New physaloid fruit‐fossil species from early Eocene South America. American Journal of Botany, 107(12), 1749–1762. doi:10.1002/ajb2.1565 https://doi.org/10.1002/ajb2.1565

Premise: Solanaceae is a scientifically and economically important angiosperm family with a minimal fossil record and an intriguing early evolutionary history. Here, we report a newly discovered fossil lantern fruit with a suite of features characteristic of Physalideae within Solanaceae. The fossil…

Joyce, E., Thiele, K., Slik, F., & Crayn, D. (2020). Checklist of the vascular flora of the Sunda-Sahul Convergence Zone. Biodiversity Data Journal, 8. doi:10.3897/bdj.8.e51094 https://doi.org/10.3897/bdj.8.e51094

Background The Sunda-Sahul Convergence Zone, defined here as the area comprising Australia, New Guinea, and Southeast Asia (Indonesia to Myanmar), straddles the Sunda and Sahul continental shelves and is one of the most biogeographically famous and important regions in the world. Floristically, it i…

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…

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…

Huang, H., Morley, R., Licht, A., Dupont-Nivet, G., Grímsson, F., Zetter, R., … Hoorn, C. (2020). Eocene palms from central Myanmar in a South-East Asian and global perspective: evidence from the palynological record. Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boaa038 https://doi.org/10.1093/botlinnean/boaa038

In the Palaeogene, pollen assemblages at low and mid latitudes are characterized by abundant palm and palm-like (PPL) taxa. Although these taxa have been widely reported, their occurrence in the Palaeogene of Myanmar remains poorly documented. Here we report on the morphology of PPL pollen along a m…
