Hookeria acutifolia Hook. & Grev. was found on Kunashir Island (South Kuril Islands, East Asia). This is the northernmost locality of the species in Asia and the first record for Russia. A description and illustrations of the species based on the Russian specimen are provided. Details on its ecology…

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…

Predicting the potential distribution of invaders is informative for pre-emptive policy or management decisions and identifying suitable areas for establishment of new populations. Temporal projection of potential distributions is complicated by the magnitude and pace of changing climate, which coul…

De la Fuente, P., Gabriel y Galán, J. M., Molino, S., Sessa, E. B., & Quintanilla, L. G. (2020). Character expression, reproductive barriers, and origin of the rare fern hybrid Asplenium ×aran-tohanum (Aspleniaceae). Plant Systematics and Evolution, 306(2). doi:10.1007/s00606-020-01658-8 https://doi.org/10.1007/s00606-020-01658-8

Hybridization is a ubiquitous force in plant evolution. In ferns, hybrids are often easily recognized by their intermediate morphology and abortive spores and thus provide a good model for studying reproductive isolating barriers between species. Asplenium ×aran-tohanum is a rare fern hybrid, despit…

Léveillé-Bourret, É., Chen, B.-H., Garon-Labrecque, M.-È., Ford, B. A., & Starr, J. R. (2019). RAD sequencing resolves the phylogeny, taxonomy and biogeography of Trichophoreae despite a rapid recent radiation (Cyperaceae). Molecular Phylogenetics and Evolution, 106727. doi:10.1016/j.ympev.2019.106727 https://doi.org/10.1016/j.ympev.2019.106727

Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial …

Mienna, I. M., Speed, J. D. M., Bendiksby, M., Thornhill, A. H., Mishler, B. D., & Martin, M. D. (2019). Differential patterns of floristic phylogenetic diversity across a post‐glacial landscape. Journal of Biogeography. doi:10.1111/jbi.13789 https://doi.org/10.1111/jbi.13789

Aim: In this study, we explored spatial patterns of phylogenetic diversity (PD) and endemism in the flora of Norway and tested hypothesized post‐glacial environmental drivers of PD, including temperature, precipitation, edaphic factors and time since glacial retreat. Location: Norway. Taxon: Vascula…

Chardon, N. I., Pironon, S., Peterson, M. L., & Doak, D. F. (2019). Incorporating intraspecific variation into species distribution models improves distribution predictions, but cannot predict species traits for a wide‐spread plant species. Ecography. doi:10.1111/ecog.04630 https://doi.org/10.1111/ecog.04630

The most common approach to predicting how species ranges and ecological functions will shift with climate change is to construct correlative species distribution models (SDMs). These models use a species’ climatic distribution to determine currently suitable areas for the species and project its po…

Mezghani, N., Khoury, C. K., Carver, D., Achicanoy, H. A., Simon, P., Flores, F. M., & Spooner, D. (2019). Distributions and Conservation Status of Carrot Wild Relatives in Tunisia: A Case Study in the Western Mediterranean Basin. Crop Science, 0(0), 0. doi:10.2135/cropsci2019.05.0333 https://doi.org/10.2135/cropsci2019.05.0333

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant species, are sources of valuable genetic resources for crop improvement. Persisting gaps in knowledge of taxonomy, distributions, and characterization for traits of interest constrain their expanded use in plan…

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.…

Fletcher, T. L., Warden, L., Sinninghe Damsté, J. S., Brown, K. J., Rybczynski, N., Gosse, J. C., & Ballantyne, A. P. (2019). Evidence for fire in the Pliocene Arctic in response to amplified temperature. Climate of the Past, 15(3), 1063–1081. doi:10.5194/cp-15-1063-2019 https://doi.org/10.5194/cp-15-1063-2019

The mid-Pliocene is a valuable time interval for investigating equilibrium climate at current atmospheric CO2 concentrations because atmospheric CO2 concentrations are thought to have been comparable to the current day and yet the climate and distribution of ecosystems were quite different. One intr…
