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…

Rozefelds, A. C., Stull, G., Hayes, P., & Greenwood, D. R. (2020). The fossil record of Icacinaceae in Australia supports long-standing Palaeo-Antarctic rainforest connections in southern high latitudes. Historical Biology, 1–11. doi:10.1080/08912963.2020.1832089 https://doi.org/10.1080/08912963.2020.1832089

Fossil fruits of Icacinaceae are recorded from two Cenozoic sites in Australia, at Launceston in northern Tasmania and the Poole Creek palaeochannel in northern South Australia, representing the first report of fossil Icacinaceae from Australia. The Launceston material includes two endocarps with br…

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…

Antibiotic resistance and viral diseases are rising around the world and are becoming major threats to global health, food security, and development. One measure that has been suggested to mitigate this crisis is the development of new antibiotics. Here, we provide a comprehensive evaluation of the …

JARAMILLO-VIVANCO, T. S., & BALSLEV, H. (2020). <p><strong>Revision of <em>Otoba</em> (Myristicaceae)</strong></p>. Phytotaxa, 441(2), 143–175. doi:10.11646/phytotaxa.441.2.3 https://doi.org/10.11646/phytotaxa.441.2.3

Otoba is one of six American genera of Myristicaceae and recognized by having three stamens with almost fused to free filaments, globose arillate seeds and absence of bracteoles in the male flower. Species of Otoba are distinguished by a suite of characters, mainly pubescence of the ovary and anther…

Molecular Phylogenetics and Evolution, 148, 106815. doi:10.1016/j.ympev.2020.106815 https://doi.org/10.1016/j.ympev.2020.106815

Species of plants with different life history strategies may differ in their seed dispersal mechanisms, impacting their distribution and diversification patterns. Shorter or longer distance dispersal is favored by different dispersal modes, facilitating (or constraining) population isolation, which …

Stropp, J., Umbelino, B., Correia, R. A., Campos-Silva, J. V., Ladle, R. J., & Malhado, A. C. M. (2020). The ghosts of forests past and future: deforestation and botanical sampling in the Brazilian Amazon. Ecography. doi:10.1111/ecog.05026 https://doi.org/10.1111/ecog.05026

The remarkable biodiversity of the Brazilian Amazon is poorly documented and threatened by deforestation. When undocumented areas become deforested, in addition to losing the fauna and flora, we lose the opportunity to know which unique species had occupied a habitat. Here we quantify such knowledge…

Ritter, C. D., Faurby, S., Bennett, D. J., Naka, L. N., ter Steege, H., Zizka, A., … Antonelli, A. (2019). The pitfalls of biodiversity proxies: Differences in richness patterns of birds, trees and understudied diversity across Amazonia. Scientific Reports, 9(1). doi:10.1038/s41598-019-55490-3 https://doi.org/10.1038/s41598-019-55490-3

Most knowledge on biodiversity derives from the study of charismatic macro-organisms, such as birds and trees. However, the diversity of micro-organisms constitutes the majority of all life forms on Earth. Here, we ask if the patterns of richness inferred for macro-organisms are similar for micro-or…

Muñoz Mazón, M., Klanderud, K., Finegan, B., Veintimilla, D., Bermeo, D., Murrieta, E., … Sheil, D. (2019). Disturbance and the elevation ranges of woody plant species in the mountains of Costa Rica. Ecology and Evolution. doi:10.1002/ece3.5870 https://doi.org/10.1002/ece3.5870

Aim: To understand how disturbance—here defined as a transient reduction in competition—can shape plant distributions along elevation gradients. Theory suggests that disturbance may increase elevation ranges, especially at the lower range limits, through reduced competitive exclusion. Nevertheless, …

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…
