Ma, D., He, Z., Bai, X., Wang, W., Zhao, P., Lin, P., & Zhou, H. (2022). Atriplex canescens, a valuable plant in soil rehabilitation and forage production. A review. Science of The Total Environment, 804, 150287. doi:10.1016/j.scitotenv.2021.150287 https://doi.org/10.1016/j.scitotenv.2021.150287

A. canescens (Pure) Nutt. is a halophytic forage shrub distributes in arid and semiarid regions, which has great use potential in disturbed lands for its strong adaptability and feeding value. At present, land degradation caused by salinization, desertification and heavy metal pollution is still exp…

De Oliveira, M. H. V., Torke, B. M., & Almeida, T. E. (2021). An inventory of the ferns and lycophytes of the Lower Tapajós River Basin in the Brazilian Amazon reveals collecting biases, sampling gaps, and previously undocumented diversity. Brittonia. doi:10.1007/s12228-021-09668-7 https://doi.org/10.1007/s12228-021-09668-7

Ferns and lycophytes are an excellent group for conservation and species distribution studies because they are closely related to environmental changes. In this study, we analyzed collection gaps, sampling biases, richness distribution, and the species conservation effectiveness of protected areas i…

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…

Roalson, E. H., & Roberts, W. R. (2016). Distinct Processes Drive Diversification in Different Clades of Gesneriaceae. Systematic Biology, 65(4), 662–684. doi:10.1093/sysbio/syw012 https://doi.org/10.1093/sysbio/syw012

Using a time-calibrated phylogenetic hypothesis including 768 Gesneriaceae species (out of ~~ 3300 species) and more than 29,000 aligned bases from 26 gene regions, we test Gesneriaceae for diversification rate shifts and the possible proximal drivers of these shifts: geographic distributions, growt…

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…

De Jesús Hernández-Hernández, M., Cruz, J. A., & Castañeda-Posadas, C. (2020). Paleoclimatic and vegetation reconstruction of the miocene southern Mexico using fossil flowers. 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…

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…

Goodwin, Z. A., Muñoz-Rodríguez, P., Harris, D. J., Wells, T., Wood, J. R. I., Filer, D., & Scotland, R. W. (2020). How long does it take to discover a species? Systematics and Biodiversity, 1–10. doi:10.1080/14772000.2020.1751339 https://doi.org/10.1080/14772000.2020.1751339

The description of a new species is a key step in cataloguing the World’s flora. However, this is only a preliminary stage in a long process of understanding what that species represents. We investigated how long the species discovery process takes by focusing on three key stages: 1, the collection …

Nevado, B., Wong, E. L. Y., Osborne, O. G., & Filatov, D. A. (2019). Adaptive Evolution Is Common in Rapid Evolutionary Radiations. Current Biology. doi:10.1016/j.cub.2019.07.059 https://doi.org/10.1016/j.cub.2019.07.059

One of the most long-standing and important mysteries in evolutionary biology is why biological diversity is so unevenly distributed across space and taxonomic lineages. Nowhere is this disparity more evident than in the multitude of rapid evolutionary radiations found on oceanic islands and mountai…
