Pang, S. E. H., De Alban, J. D. T., & Webb, E. L. (2021). Effects of climate change and land cover on the distributions of a critical tree family in the Philippines. Scientific Reports, 11(1). doi:10.1038/s41598-020-79491-9 https://doi.org/10.1038/s41598-020-79491-9

Southeast Asian forests are dominated by the tree family Dipterocarpaceae, whose abundance and diversity are key to maintaining the structure and function of tropical forests. Like most biodiversity, dipterocarps are threatened by deforestation and climate change, so it is crucial to understand the …

Allstädt, F. J., Koutsodendris, A., Appel, E., Rösler, W., Reichgelt, T., Kaboth-Bahr, S., … Pross, J. (2021). Late Pliocene to early Pleistocene climate dynamics in western North America based on a new pollen record from paleo-Lake Idaho. Palaeobiodiversity and Palaeoenvironments. doi:10.1007/s12549-020-00460-1 https://doi.org/10.1007/s12549-020-00460-1

Marked by the expansion of ice sheets in the high latitudes, the intensification of Northern Hemisphere glaciation across the Plio/Pleistocene transition at ~ 2.7 Ma represents a critical interval of late Neogene climate evolution. To date, the characteristics of climate change in North America duri…

Ortiz, A. M. D., & Torres, J. N. V. (2020). Assessing the Impacts of Agriculture and Its Trade on Philippine Biodiversity. Land, 9(11), 403. doi:10.3390/land9110403 https://doi.org/10.3390/land9110403

Many Philippine species are at risk of extinction because of habitat loss and degradation driven by agricultural land use and land-use change. The Philippines is one of the world’s primary banana and pineapple producers. The input-intensive style of plantation agriculture for these typically exporte…

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…

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…

Bellot, S., Bayton, R. P., Couvreur, T. L. P., Dodsworth, S., Eiserhardt, W. L., Guignard, M. S., … Baker, W. J. (2020). On the origin of giant seeds: the macroevolution of the double coconut ( Lodoicea maldivica ) and its relatives (Borasseae, Arecaceae). New Phytologist. doi:10.1111/nph.16750 https://doi.org/10.1111/nph.16750

Seed size shapes plant evolution and ecosystems, and may be driven by plant size and architecture, dispersers, habitat and insularity. How these factors influence the evolution of giant seeds is unclear, as are the rate of evolution and the biogeographical consequences of giant seeds. We generated D…

De Lima, V. V. F., Scariot, A., & Sevilha, A. C. (2020). Predicting the distribution of Syagrus coronata palm: challenges for the conservation of an important resource in northeastern Brazil. Flora, 151607. doi:10.1016/j.flora.2020.151607 https://doi.org/10.1016/j.flora.2020.151607

The palm Syagrus coronata plays an important ecological role in the caatinga ecosystems and is a source of income and livelihood for rural communities in semiarid northeastern Brazil. Despite its ecological and socioeconomic importance, little is known about the environmental factors determining its…

Rivera, D., Abellán, J., Palazón, J. A., Obón, C., Alcaraz, F., Carreño, E., … Johnson, D. (2020). Modelling ancient areas for date palms (Phoenix species: Arecaceae): Bayesian analysis of biological and cultural evidence. Botanical Journal of the Linnean Society, 193(2), 228–262. doi:10.1093/botlinnean/boaa011 https://doi.org/10.1093/botlinnean/boaa011

Our aim in this study is to build a model for the expansion of date palms (Phoenix spp., Arecaceae) that can be linked to domestication processes. Palaeontological and archaeobotanical evidence concerning date palm is extremely diversified around the Mediterranean Basin and in West Asia, mainly cons…
