Moore, M. P., Hersch, K., Sricharoen, C., Lee, S., Reice, C., Rice, P., … Fowler-Finn, K. D. (2021). Sex-specific ornament evolution is a consistent feature of climatic adaptation across space and time in dragonflies. Proceedings of the National Academy of Sciences, 118(28), e2101458118. doi:10.1073/pnas.2101458118 https://doi.org/10.1073/pnas.2101458118

Adaptation to different climates fuels the origins and maintenance of biodiversity. Detailing how organisms optimize fitness for their local climates is therefore an essential goal in biology. Although we increasingly understand how survival-related traits evolve as organisms adapt to climatic condi…

Hemberger, J., Crossley, M. S., & Gratton, C. (2021). Historical decrease in agricultural landscape diversity is associated with shifts in bumble bee species occurrence. Ecology Letters. doi:10.1111/ele.13786 https://doi.org/10.1111/ele.13786

Agricultural intensification is a key suspect among putative drivers of recent insect declines, but an explicit link between historical change in agricultural land cover and insect occurrence is lacking. Determining whether agriculture impacts beneficial insects (e.g. pollinators), is crucial to enh…

Tabor, J. A., & Koch, J. B. (2021). Ensemble Models Predict Invasive Bee Habitat Suitability Will Expand under Future Climate Scenarios in Hawai’i. Insects, 12(5), 443. doi:10.3390/insects12050443 https://doi.org/10.3390/insects12050443

Climate change is predicted to increase the risk of biological invasions by increasing the availability of climatically suitable regions for invasive species. Endemic species on oceanic islands are particularly sensitive to the impact of invasive species due to increased competition for shared resou…

Ji, Y. (2021). The geographical origin, refugia, and diversification of honey bees (Apis spp.) based on biogeography and niche modeling. Apidologie. doi:10.1007/s13592-020-00826-6 https://doi.org/10.1007/s13592-020-00826-6

An understanding of the origin and formation of biodiversity and distribution patterns can provide a theoretical foundation for biodiversity conservation. In this study, phylogeny and biogeography analyses based on mitochondrial genomes and niche modeling based on occurrence records were performed t…

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…

Li, X., Li, B., Wang, G., Zhan, X., & Holyoak, M. (2020). Deeply digging the interaction effect in multiple linear regressions using a fractional-power interaction term. MethodsX, 7, 101067. doi:10.1016/j.mex.2020.101067 https://doi.org/10.1016/j.mex.2020.101067

In multiple regression Y ~ β0 + β1X1 + β2X2 + β3X1 X2 + ɛ., the interaction term is quantified as the product of X1 and X2. We developed fractional-power interaction regression (FPIR), using βX1M X2N as the interaction term. The rationale of FPIR is that the slopes of Y-X1 regression along the X2 gr…

Medina, A. M., & Almeida-Neto, M. (2020). Grinnelian and Eltonian niche conservatism of the European honeybee (Apis mellifera) in its exotic distribution. Sociobiology, 67(2), 239. doi:10.13102/sociobiology.v67i2.4901 https://doi.org/10.13102/sociobiology.v67i2.4901

The understanding of how niche-related traits change during species invasion have prompted what is now known as the niche conservatism principle. Most studies that have tested the niche conservatism principle have focused on the extent to which the species’ climatic niches remain stable in their exo…

Liu, X., Blackburn, T. M., Song, T., Wang, X., Huang, C., & Li, Y. (2020). Animal invaders threaten protected areas worldwide. Nature Communications, 11(1). doi:10.1038/s41467-020-16719-2 https://doi.org/10.1038/s41467-020-16719-2

Protected areas are the cornerstone of biodiversity conservation. However, alien species invasion is an increasing threat to biodiversity, and the extent to which protected areas worldwide are resistant to incursions of alien species remains poorly understood. Here, we investigate establishment by 8…

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…

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…
