Howard, C. C., & Cellinese, N. (2020). Tunicate bulb size variation in monocots explained by temperature and phenology. Ecology and Evolution. doi:10.1002/ece3.5996 https://doi.org/10.1002/ece3.5996

Plant bulbs are modified shoot systems comprised of short internodes with apical bud(s) surrounded by layers of leaf bases. Bulb diameters can vary greatly, with overall bulb size playing a role in flower formation and resource allocation. Despite the importance of bulb size to the overall fitness o…

Oyedeji Amusa, M. O., Van Wyk, B.-E., & Oskolski, A. (2020). Wood anatomy of South African Meliaceae: evolutionary and ecological implications. Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boaa010 https://doi.org/10.1093/botlinnean/boaa010

Wood structure in seven South African species of Ekebergia, Nymania, Trichilia and Turraea (Meliaceae) was studied and compared with data for other genera of the subfamily Melioideae to elucidate phylogenetic relationships and pathways of trait evolution in this group and to clarify the ecological s…

Avila, C., Angulo-Preckler, C., Martín-Martín, R. P., Figuerola, B., Griffiths, H. J., & Waller, C. L. (2020). Invasive marine species discovered on non–native kelp rafts in the warmest Antarctic island. Scientific Reports, 10(1). doi:10.1038/s41598-020-58561-y https://doi.org/10.1038/s41598-020-58561-y

Antarctic shallow coastal marine communities were long thought to be isolated from their nearest neighbours by hundreds of kilometres of deep ocean and the Antarctic Circumpolar Current. The discovery of non–native kelp washed up on Antarctic beaches led us to question the permeability of these barr…

Teshera-Levye, J., Miles, B., Terwilliger, V., Lovelock, C. E., & Cavender-Bares, J. (2019). Drivers of habitat partitioning among three Quercus species along a hydrologic gradient. Tree Physiology. doi:10.1093/treephys/tpz112 https://doi.org/10.1093/treephys/tpz112

A critical process that allows multiple, similar species to coexist in an ecological community is their ability to partition local habitat gradients. The mechanisms that underlie this separation at local scales may include niche differences associated with their biogeographic history, differences in…

Kass, J. M., Anderson, R. P., Espinosa‐Lucas, A., Juárez‐Jaimes, V., Martínez‐Salas, E., Botello, F., … Sánchez‐Cordero, V. (2019). Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in Mexico. Ecography. doi:10.1111/ecog.04886 https://doi.org/10.1111/ecog.04886

Although long‐standing theory suggests that biotic variables are only relevant at local scales for explaining the patterns of species’ distributions, recent studies have demonstrated improvements to species distribution models (SDMs) by incorporating predictor variables informed by biotic interactio…

Stull, G., Tiffney, B. H., Manchester, S. R., Rio, C. D., & Wing, S. L. (2019). Endocarps of Pyrenacantha (Icacinaceae) from the early Oligocene of Egypt. International Journal of Plant Sciences. doi:10.1086/706854 https://doi.org/10.1086/706854

The fossil record of Pyrenacantha (Phytocreneae tribe, Icacinaceae) includes well-documented species from the Paleogene of North and South America but, to date, no fossils have been described from its present geographic range, the Old World tropics. We document endocarp remains from the early Oligoc…

Afonin, A. N., Fedorova, Y. A., & Li, Y. S. (2019). Characterization of the Occurrence and Abundance of the Common Ragweed (Ambrosia artemisiifolia L.) with Regard to Assessment of Its Expansion Potential in European Russia. Russian Journal of Biological Invasions, 10(3), 220–226. doi:10.1134/s2075111719030032 https://doi.org/10.1134/S2075111719030032

A field study of common ragweed (Ambrosia artemisiifolia L.) in European Russia provided information on the occurrence and abundance of the species and enabled a prediction of the possible boundaries of species naturalization. As a result, the understanding of the ecological limits of common ragweed…

Marconi, L., & Armengot, L. (2020). Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment, 287, 106664. doi:10.1016/j.agee.2019.106664 https://doi.org/10.1016/j.agee.2019.106664

In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…

[1]P. Talhinhas, “An annotated checklist of rust fungi (Pucciniales) occurring in Portugal,” Sydowia An International Journal of Mycology, vol. 71, pp. 65–84, Jun. 2019. https://doi.org/10.12905/0380.sydowia71-2019-0065

In this work we have retrieved and analysed data for 2319 occurrences of rust fungi from 246 Pucciniales taxa in Portugal based on 115 publications and our own surveys, totalizing 683 rust taxon-host taxon unique combinations. This list was updated according to current taxonomic framework and georef…

Han, T., Zheng, Q., Onstein, R. E., Rojas‐Andrés, B. M., Hauenschild, F., Muellner‐Riehl, A. N., & Xing, Y. (2019). Polyploidy promotes species diversification of Allium through ecological shifts. New Phytologist. doi:10.1111/nph.16098 https://doi.org/10.1111/nph.16098

Despite the role of polyploidy in multiple evolutionary processes, its impact on plant diversification remains controversial. An increased polyploid frequency may facilitate speciation through shifts in ecology, morphology, or both. Here we used Allium to evaluate (1) the relationship between intras…
