Bontrager, M., Usui, T., Lee‐Yaw, J. A., Anstett, D. N., Branch, H. A., Hargreaves, A. L., … Angert, A. L. (2021). Adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion. Evolution. doi:10.1111/evo.14231 https://doi.org/10.1111/evo.14231

Every species experiences limits to its geographic distribution. Some evolutionary models predict that populations at range edges are less well‐adapted to their local environments due to drift, expansion load, or swamping gene flow from the range interior. Alternatively, populations near range edges…

Orr, M. C., Hughes, A. C., Chesters, D., Pickering, J., Zhu, C.-D., & Ascher, J. S. (2020). Global Patterns and Drivers of Bee Distribution. Current Biology. doi:10.1016/j.cub.2020.10.053 https://doi.org/10.1016/j.cub.2020.10.053

Insects are the focus of many recent studies suggesting population declines, but even invaluable pollination service providers such as bees lack a modern distributional synthesis. Here, we combine a uniquely comprehensive checklist of bee species distributions and >5,800,000 public bee occurrence re…

Grünig, M., Calanca, P., Mazzi, D., & Pellissier, L. (2020). Inflection point in climatic suitability of insect pest species in Europe suggests non‐linear responses to climate change. Global Change Biology. doi:10.1111/gcb.15313 https://doi.org/10.1111/gcb.15313

Climate change and globalization affect the suitable conditions for agricultural crops and insect pests, threatening future food security. It remains unknown whether shifts in species’ climatic suitability will be linear or rather non‐linear, with crop exposure to pests suddenly increasing when a cr…

Daniel, J., Horrocks, J., & Umphrey, G. J. (2019). Efficient Modelling of Presence-Only Species Data via Local Background Sampling. Journal of Agricultural, Biological and Environmental Statistics. doi:10.1007/s13253-019-00380-4 https://doi.org/10.1007/s13253-019-00380-4

In species distribution modelling, records of species presence are often modelled as a realization of a spatial point process whose intensity is a function of environmental covariates. One way to fit a spatial point process model is to apply logistic regression to an artificial case–control sample c…

Ezray, B. D., Wham, D. C., Hill, C. E., & Hines, H. M. (2019). Unsupervised machine learning reveals mimicry complexes in bumblebees occur along a perceptual continuum. Proceedings of the Royal Society B: Biological Sciences, 286(1910), 20191501. doi:10.1098/rspb.2019.1501 https://doi.org/10.1098/rspb.2019.1501

Müllerian mimicry theory states that frequency-dependent selection should favour geographical convergence of harmful species onto a shared colour pattern. As such, mimetic patterns are commonly circumscribed into discrete mimicry complexes, each containing a predominant phenotype. Outside a few exam…

Müller, A., Prosi, R., Praz, C., & Richter, H. (2019). Nesting in bark – the peculiar life history of the rare boreoalpine osmiine bee Osmia (Melanosmia) nigriventris (Hymenoptera, Megachilidae). Alpine Entomology, 3, 105–119. doi:10.3897/alpento.3.34409 https://doi.org/10.3897/alpento.3.34409

Osmia (Melanosmia) nigriventris (Zetterstedt) is a predominantly boreoalpine megachilid bee species, whose biology is poorly known due to its pronounced rarity all over Central Europe. The discovery of 19 nests in the Grisons and Valais (Switzerland) allowed for the investigation of its nesting biol…

Looney, C., Strange, J. P., Freeman, M., & Jennings, D. (2019). The expanding Pacific Northwest range of Bombus impatiens Cresson and its establishment in Washington State. Biological Invasions. doi:10.1007/s10530-019-01970-6 https://doi.org/10.1007/s10530-019-01970-6

Bombus impatiens, the common eastern bumble bee, is the first bumble bee established outside of its native range in North America. Native to the eastern portion of the continent, the species was imported to British Columbia in the early 2000s for greenhouse pollination and subsequently became establ…

Wan, J.-Z., Wang, C.-J., & Yu, F.-H. (2019). Large-scale environmental niche variation between clonal and non-clonal plant species: Roles of clonal growth organs and ecoregions. Science of The Total Environment, 652, 1071–1076. doi:10.1016/j.scitotenv.2018.10.280 https://doi.org/10.1016/j.scitotenv.2018.10.280

Clonal plant species can produce genetically identical and potentially independent offspring, and dominate a variety of habitats. The divergent evolutionary mechanisms between clonal and non-clonal plants are interesting areas of ecological research. A number of studies have shown that the environme…
