Scrivanti, L. R., & Anton, A. M. (2021). Impact of climate change on the Andean distribution of Poa scaberula (Poaceae). Flora, 278, 151805. doi:10.1016/j.flora.2021.151805 https://doi.org/10.1016/j.flora.2021.151805

Grasslands play an important ecological role and are the dominant landscape in the whole extent of the Andes and high elevation regions of South America. Climate change models indicate a strong impact on mountain systems. The climatic conditions of mountain systems are greatly influenced by topograp…

Hambuckers, A., de Harenne, S., Rocha Ledezma, E., Zúñiga Zeballos, L., & François, L. (2021). Predicting the Future Distribution of Ara rubrogenys, an Endemic Endangered Bird Species of the Andes, Taking into Account Trophic Interactions. Diversity, 13(2), 94. doi:10.3390/d13020094 https://doi.org/10.3390/d13020094

Species distribution models (SDMs) are commonly used with climate only to predict animal distribution changes. This approach however neglects the evolution of other components of the niche, like food resource availability. SDMs are also commonly used with plants. This also suffers limitations, notab…

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…

Quiroga, R. E., Premoli, A. C., & Fernández, R. J. (2020). Niche dynamics in amphitropical desert disjunct plants: Seeking for ecological and species‐specific influences. Global Ecology and Biogeography. doi:10.1111/geb.13215 https://doi.org/10.1111/geb.13215

Aim: Numerous studies have assessed whether species niches are conserved in geographically separated regions. However, most of them were performed on invasive species, with the limitation that such species have likely not yet reached their potential distribution in the invaded region. Here we test t…

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…

Zizka, A., Antunes Carvalho, F., Calvente, A., Rocio Baez-Lizarazo, M., Cabral, A., Coelho, J. F. R., … Antonelli, A. (2020). No one-size-fits-all solution to clean GBIF. PeerJ, 8, e9916. doi:10.7717/peerj.9916 https://doi.org/10.7717/peerj.9916

Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, th…

Mapaura, A., Canavan, K., Richardson, D. M., Clark, V. R., & Steenhuisen, S.-L. (2020). The invasive grass genus Nassella in South Africa: A synthesis. South African Journal of Botany, 135, 336–348. doi:10.1016/j.sajb.2020.08.031 https://doi.org/10.1016/j.sajb.2020.08.031

Three species of Nassella have naturalized in South Africa. Nassella trichotoma and N. tenuissima are declared weeds under category 1b of the National Environmental Management: Biodiversity Act (NEM:BA) and occur mainly in the montane grasslands of the Western and Eastern Cape provinces. Nassella ne…

Brightly, W. H., Hartley, S. E., Osborne, C. P., Simpson, K. J., & Strömberg, C. A. E. (2020). High silicon concentrations in grasses are linked to environmental conditions and not associated with C 4 photosynthesis. Global Change Biology. doi:10.1111/gcb.15343 https://doi.org/10.1111/gcb.15343

The uptake and deposition of silicon (Si) as silica phytoliths is common among land plants and is associated with a variety of functions. Among these, herbivore defense has received significant attention, particularly with regards to grasses and grasslands. Grasses are well known for their high sili…

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…

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…
