Zizka, A., Antunes Carvalho, F., Calvente, A., Rocio Baez-Lizarazo, M., Cabral, A., Coelho, J. F. R., … Antonelli, A. (2020). No one-size-fits-all solution to clean GBIF. PeerJ, 8, e9916. doi:10.7717/peerj.9916 https://doi.org/10.7717/peerj.9916

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…

Deb, J. C., Forbes, G., & MacLean, D. A. (2020). Modelling the spatial distribution of selected North American woodland mammals under future climate scenarios. Mammal Review. doi:10.1111/mam.12210 https://doi.org/10.1111/mam.12210

North America has a diverse array of mammalian species. Model projections indicate significant variations in future climate conditions of North America, and the habitats of woodland mammals of this continent may be particularly sensitive to changes in climate.We report on the potential spatial distr…

Aguiar, L. M. S., Pereira, M. J. R., Zortéa, M., & Machado, R. B. (2020). Where are the bats? An environmental complementarity analysis in a megadiverse country. Diversity and Distributions. doi:10.1111/ddi.13137 https://doi.org/10.1111/ddi.13137

Aim: Field surveys are necessary to overcome Wallacean shortfalls. The task is even more important when human pressure on tropical—megadiverse—ecosystems is considered. However, due to financial constraints, spatial and temporal prioritization is required. Here, we used the concept of environmental …

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…

Romero‐Muñoz, A., Benítez‐López, A., Zurell, D., Baumann, M., Camino, M., Decarre, J., … Kuemmerle, T. (2020). Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco. Ecography. doi:10.1111/ecog.05053 https://doi.org/10.1111/ecog.05053

Habitat destruction and overexploitation are the main threats to biodiversity and where they co‐occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of these threats is lacking, including where they overlap and how they change over…

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…

Escalante, T., Varela-Anaya, A. M., Noguera-Urbano, E. A., Elguea-Manrique, L. M., Ochoa-Ochoa, L. M., Gutiérrez-Velázquez, A. L., … Rodríguez-Soto, C. (2020). Evaluation of five taxa as surrogates for conservation prioritization in the Transmexican Volcanic Belt, Mexico. Journal for Nature Conservation, 125800. doi:10.1016/j.jnc.2020.125800 https://doi.org/10.1016/j.jnc.2020.125800

Many biotic groups have been proposed as biodiversity surrogates; however, using different taxa could provide complementary information for choosing conservation priorities. There are two general ways to evaluate the performance of surrogates: (1) using cross-taxon congruency as an a priori test, be…

This study has developed a GIS framework that uses spatial environmental and climate data to better understand areas on Earth that share the most environmental similarities to Mars. The purpose of developing this framework is to determine which vegetation is most likely to survive in closed bioregen…

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…
