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…

Grattarola, F., González, A., Mai, P., Cappuccio, L., Fagúndez-Pachón, C., Rossi, F., … Pincheira-Donoso, D. (2020). Biodiversidata: A novel dataset for the vascular plant species diversity in Uruguay. Biodiversity Data Journal, 8. doi:10.3897/bdj.8.e56850 https://doi.org/10.3897/bdj.8.e56850

South America hosts some of the world’s most prominent biodiversity hotspots. Yet, Uruguay – a country where multiple major ecosystems converge – ranks amongst the countries with the lowest levels of available digital biodiversity data in the continent. Such prevalent data scarcity has significantly…

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…

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…

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…

Chevalier, M., Chase, B. M., Quick, L. J., Dupont, L. M., & Johnson, T. C. (2020). Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology. doi:10.1130/g47841.1 https://doi.org/10.1130/G47841.1

Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…

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…

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 …
