David, K. T., & Halanych, K. M. (2021). Spatial proximity between polyploids across South American frog genera. Journal of Biogeography. doi:10.1111/jbi.14067 https://doi.org/10.1111/jbi.14067

Aim: Polyploids have been theorized to occur more frequently in environments that are subjected to severe conditions or sudden disruptions. Here we test the expectation that polyploid taxa occur more frequently in extreme or disrupted environments than their diploid counterparts, whether due to inc…

Ellestad, P., Forest, F., Serpe, M., Novak, S. J., & Buerki, S. (2021). Harnessing large-scale biodiversity data to infer the current distribution of Vanilla planifolia (Orchidaceae). Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boab005 https://doi.org/10.1093/botlinnean/boab005

Although vanilla is one of the most popular flavours in the world, there is still uncertainty concerning the native distribution of the species that produces it, Vanilla planifolia. To circumscribe the native geographical extent of this economically important species more precisely, we propose a new…

Freitas-Oliveira, R., Hannibal, W., Lima-Ribeiro, M. S., & Terribile, L. C. (2021). Implications of climate change for the distribution of the water opossum (Chironectes minimus): habitat loss and conservation opportunities. Mammalian Biology. doi:10.1007/s42991-021-00105-6 https://doi.org/10.1007/s42991-021-00105-6

Climate change is expected to impact the geographic distribution of marsupial species in the near future and this impact is likely to be accentuated for the more specialist species. The water opossum (Chironectes minimus) is the only semiaquatic marsupial in the world and is considered naturally rar…

González-Saucedo, Z. Y., González-Bernal, A., & Martínez-Meyer, E. (2021). Identifying priority areas for landscape connectivity for three large carnivores in northwestern Mexico and southwestern United States. Landscape Ecology. doi:10.1007/s10980-020-01185-4 https://doi.org/10.1007/s10980-020-01185-4

Context: Large carnivores are crucial to ecosystem functioning, as they enhance the biodiversity of the native communities in which they live. However, most large carnivores are threatened with extinction resulting from human persecution, habitat encroachment, and the loss of habitat connectivity. …

Espinosa, C. C., Trigo, T. C., Tirelli, F. P., da Silva, L. G., Eizirik, E., Queirolo, D., … de Freitas, T. R. O. (2017). Geographic distribution modeling of the margay (Leopardus wiedii) and jaguarundi (Puma yagouaroundi): a comparative assessment. Journal of Mammalogy, 99(1), 252–262. doi:10.1093/jmammal/gyx152 https://doi.org/10.1093/jmammal/gyx152

The Neotropical region currently harbors 8 recognized species of small cats, including the margay (Leopardus wiedii) and jaguarundi (Puma yagouaroundi). These similar-sized species have broad geographic distributions and commonly occur in sympatry. We constructed species occurrence databases and use…

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…

Tan, K., Lu, T., & Ren, M.-X. (2020). Biogeography and evolution of Asian Gesneriaceae based on updated taxonomy. PhytoKeys, 157, 7–26. doi:10.3897/phytokeys.157.34032 https://doi.org/10.3897/phytokeys.157.34032

Based on an updated taxonomy of Gesneriaceae, the biogeography and evolution of the Asian Gesneriaceae are outlined and discussed. Most of the Asian Gesneriaceae belongs to Didymocarpoideae, except Titanotrichum was recently moved into Gesnerioideae. Most basal taxa of the Asian Gesneriaceae are fou…

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 …

Goodwin, Z. A., Muñoz-Rodríguez, P., Harris, D. J., Wells, T., Wood, J. R. I., Filer, D., & Scotland, R. W. (2020). How long does it take to discover a species? Systematics and Biodiversity, 1–10. doi:10.1080/14772000.2020.1751339 https://doi.org/10.1080/14772000.2020.1751339

The description of a new species is a key step in cataloguing the World’s flora. However, this is only a preliminary stage in a long process of understanding what that species represents. We investigated how long the species discovery process takes by focusing on three key stages: 1, the collection …

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…
