Azevedo, J. A. R., Guedes, T. B., Nogueira, C. de C., Passos, P., Sawaya, R. J., Prudente, A. L. C., … Antonelli, A. (2019). Museums and cradles of diversity are geographically coincident for narrowly distributed Neotropical snakes. Ecography, 43(2), 328–339. doi:10.1111/ecog.04815 https://doi.org/10.1111/ecog.04815

Factors driving the spatial configuration of centres of endemism have long been a topic of broad interest and debate. Due to different eco‐evolutionary processes, these highly biodiverse areas may harbour different amounts of ancient and recently diverged organisms (paleo‐ and neo‐endemism, respecti…

Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, th…

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…

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…

Representation of Threatened Biodiversity in Protected Areas and Identification of Complementary Areas for Their Conservation: Plethodontid Salamanders in Mexico. Tropical Conservation Science, 12, 194008291983415. doi:10.1177/1940082919834156 https://doi.org/10.1177/1940082919834156

Protected areas (PAs) have been the most important conservation instrument worldwide and are reaching the coverage percentage suggested internationally (17%), but with the risk of not being ecologically representative, which is particularly concerning for threatened species. Using a database of reco…

The American tropics (the Neotropics) are the most species-rich realm on Earth, and for centuries, scientists have attempted to understand the origins and evolution of their biodiversity. It is now clear that different regions and taxonomic groups have responded differently to geological and climati…

Guedes, T. B., Sawaya, R. J., Zizka, A., Laffan, S., Faurby, S., Pyron, R. A., … Antonelli, A. (2017). Patterns, biases and prospects in the distribution and diversity of Neotropical snakes. Global Ecology and Biogeography, 27(1), 14–21. doi:10.1111/geb.12679 https://doi.org/10.1111/geb.12679

Motivation: We generated a novel database of Neotropical snakes (one of the world’s richest herpetofauna) combining the most comprehensive, manually compiled distribution dataset with publicly available data. We assess, for the first time, the diversity patterns for all Neotropical snakes as well as…
