Lindberg, C. L., Hanslin, H. M., Schubert, M., Marcussen, T., Trevaskis, B., Preston, J. C., & Fjellheim, S. (2020). Increased above ground resource allocation is a likely precursor for independent evolutionary origins of annuality in the Pooideae grass subfamily. New Phytologist. doi:10.1111/nph.16666 https://doi.org/10.1111/nph.16666

Semelparous annual plants flower a single time during their one‐year life cycle, investing much of their energy into rapid reproduction. In contrast, iteroparous perennial plants flower multiple times over several years, and partition their resources between reproduction and persistence. To which ex…

Arfianti, T., & Costello, M. (2020). Global biogeography of marine amphipod crustaceans: latitude, regionalization, and beta diversity. Marine Ecology Progress Series, 638, 83–94. doi:10.3354/meps13272 https://doi.org/10.3354/meps13272

Studying the biogeography of amphipod crustaceans is of interest because they play an important role at lower trophic levels in ecosystems. Because they lack a planktonic larval stage, it has been hypothesized that marine benthic amphipod crustaceans may have short dispersal distances, high endemici…

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…

Folk, R. A., Stubbs, R. L., Mort, M. E., Cellinese, N., Allen, J. M., Soltis, P. S., … Guralnick, R. P. (2019). Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences, 116(22), 10874–10882. doi:10.1073/pnas.1817999116 https://doi.org/10.1073/pnas.1817999116

Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. Such density-dependent models imply tight linkages between diversification and…
