Iannella, M., D’Alessandro, P., De Simone, W., & Biondi, M. (2021). Habitat Specificity, Host Plants and Areas of Endemism for the Genera-Group Blepharida s.l. in the Afrotropical Region (Coleoptera, Chrysomelidae, Galerucinae, Alticini). Insects, 12(4), 299. doi:10.3390/insects12040299 https://doi.org/10.3390/insects12040299

The genus Calotheca Heyden (Chrysomelidae) is mainly distributed in the eastern and southern parts of sub-Saharan Africa, with some extensions northward, while Blepharidina Bechyné occurs in the intertropical zone of Africa, with two subgenera, Blepharidina s. str. and Blepharidina(Afroblepharida) B…

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…

Iqbal, I., Shabbir, A., Shabbir, K., Barkworth, M., Bareen, F., & Khan, S. (2020). Evolvulus nummularius (L.) L. (Convolvulaceae): a new alien plant record for Pakistan. BioInvasions Records, 9(4), 702–711. doi:10.3391/bir.2020.9.4.04 https://doi.org/10.3391/bir.2020.9.4.04

Evolvulus nummularius (L.) L., a member of the Convolvulaceae, is native to Mexico and South America but nowadays grows around the world in many tropical and subtropical regions. Its presence in Pakistan, where it has become naturalized, is reported here for the first time. It was first discovered i…

Magri, D., Parra, I., Di Rita, F., Ni, J., Shichi, K., & Worth, J. R. P. (2020). Linking worldwide past and present conifer vulnerability. Quaternary Science Reviews, 250, 106640. doi:10.1016/j.quascirev.2020.106640 https://doi.org/10.1016/j.quascirev.2020.106640

Inventories of species recently extinct or threatened with extinction may be found in global databases. However, despite the large number of published fossil based-studies, specific databases on the vulnerability of species in the past are not available. We compiled a worldwide database of published…

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…

Davies, T. J., Daru, B. H., Bezeng, B. S., Charles-Dominique, T., Hempson, G. P., Kabongo, R. M., … Bond, W. J. (2020). Savanna tree evolutionary ages inform the reconstruction of the paleoenvironment of our hominin ancestors. Scientific Reports, 10(1). doi:10.1038/s41598-020-69378-0 https://doi.org/10.1038/s41598-020-69378-0

Ideas on hominin evolution have long invoked the emergence from forests into open habitats as generating selection for traits such as bipedalism and dietary shifts. Though controversial, the savanna hypothesis continues to motivate research into the palaeo-environments of Africa. Reconstruction of t…

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 …

Peyre, G., Lenoir, J., Karger, D. N., Gomez, M., Gonzalez, A., Broennimann, O., & Guisan, A. (2020). The fate of páramo plant assemblages in the sky islands of the northern Andes. Journal of Vegetation Science. doi:10.1111/jvs.12898 https://doi.org/10.1111/jvs.12898

Aims: Assessing climate change impacts on biodiversity is a main scientific challenge, especially in the tropics, therefore, we predicted the future of plant species and communities on the unique páramo sky islands. We implemented the Spatially Explicit Species Assemblage Modelling framework, by i) …

Ringelberg, J. J., Zimmermann, N. E., Weeks, A., Lavin, M., & Hughes, C. E. (2020). Biomes as evolutionary arenas: Convergence and conservatism in the trans‐continental succulent biome. Global Ecology and Biogeography. doi:10.1111/geb.13089 https://doi.org/10.1111/geb.13089

Aim: Historically, biomes have been defined based on their structurally and functionally similar vegetation, but there is debate about whether these similarities are superficial, and about how biomes are defined and mapped. We propose that combined assessment of evolutionary convergence of plant fun…
