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…

Cardador, L., & Blackburn, T. M. (2020). A global assessment of human influence on niche shifts and risk predictions of bird invasions. Global Ecology and Biogeography. doi:10.1111/geb.13166 https://doi.org/10.1111/geb.13166

Aim: Estimating the strength of niche conservatism is key for predictions of invasion risk. Most studies consider only the climatic niche, but other factors, such as human disturbance, also shape niches. Whether occupation of human habitats in the alien range depends on the native tolerances of spec…

Pili, A. N., Tingley, R., Sy, E. Y., Diesmos, M. L. L., & Diesmos, A. C. (2020). Niche shifts and environmental non-equilibrium undermine the usefulness of ecological niche models for invasion risk assessments. Scientific Reports, 10(1). doi:10.1038/s41598-020-64568-2 https://doi.org/10.1038/s41598-020-64568-2

Niche shifts and environmental non-equilibrium in invading alien species undermine niche-based predictions of alien species’ potential distributions and, consequently, their usefulness for invasion risk assessments. Here, we compared the realized climatic niches of four alien amphibian species (Hyla…

Pappalardo, P., Morales‐Castilla, I., Park, A. W., Huang, S., Schmidt, J. P., & Stephens, P. R. (2019). Comparing methods for mapping global parasite diversity. Global Ecology and Biogeography. doi:10.1111/geb.13008 https://doi.org/10.1111/geb.13008

Aim: Parasites are a major component of global ecosystems, yet spatial variation in parasite diversity is poorly known, largely because their occurrence data are limited and thus difficult to interpret. Using a recently compiled database of parasite occurrences, we compare different models which we …

Weterings, R., Barbetti, M., & Buckley, H. L. (2019). Hypothesis: Do invasive house geckos exacerbate dengue fever epidemics? Biological Invasions. doi:10.1007/s10530-019-02066-x https://doi.org/10.1007/s10530-019-02066-x

Dengue fever is a mosquito-borne disease that has undergone a marked rise in incidence since the 1950s, throughout the world’s tropical regions. Here, we present a hypothesis that this rise in incidence may have been exacerbated by the invasion of house geckos, due to their role in the mosquito vect…

China’s Belt and Road Initiative (BRI) is an unprecedented global development program that involves nearly half of the world’s countries [1]. It not only will have economic and political influences, but also may generate multiple environmental challenges and is a focus of considerable academic and p…

Mothes, C. C., Stroud, J. T., Clements, S. L., & Searcy, C. A. (2019). Evaluating ecological niche model accuracy in predicting biotic invasions using South Florida’s exotic lizard community. Journal of Biogeography, 46(2), 432–441. doi:10.1111/jbi.13511 https://doi.org/10.1111/jbi.13511

Aim: Predicting environmentally suitable areas for non‐native species is an important step in managing biotic invasions, and ecological niche models are commonly used to accomplish this task. Depending on these models to enact appropriate management plans assumes their accuracy, but most niche model…

Faurby, S., & Araújo, M. B. (2018). Anthropogenic range contractions bias species climate change forecasts. Nature Climate Change, 8(3), 252–256. doi:10.1038/s41558-018-0089-x https://doi.org/10.1038/s41558-018-0089-x

Forecasts of species range shifts under climate change most often rely on ecological niche models, in which characterizations of climate suitability are highly contingent on the species range data used. If ranges are far from equilibrium under current environmental conditions, for instance owing to …
