Cruz, J. A., Alarcón-D, I., Figueroa-Castro, D. M., & Castañeda-Posadas, C. (2020). Fossil pigmy rattlesnake inside the mandible of an American mastodon and use of fossil reptiles for the paleoclimatic reconstruction of a Pleistocene locality in Puebla, Mexico. Quaternary International. doi:10.1016/j.quaint.2020.10.058 https://doi.org/10.1016/j.quaint.2020.10.058

Records of Pleistocene reptiles are relatively well known in different countries. However, reptile fossil records of Pleistocene from Latin America are scarce and limited to presence data associated with records of megafauna remains. Taphonomic studies in Pleistocene reptiles are focused on finding …

Benavides, L. R., Pinto-da-Rocha, R., & Giribet, G. (2020). The phylogeny and evolution of the flashiest of the armored harvestmen (Arachnida: Opiliones). Systematic Biology. doi:10.1093/sysbio/syaa080 https://doi.org/10.1093/sysbio/syaa080

Gonyleptoidea, largely restricted to the Neotropics, constitutes the most diverse superfamily of Opiliones and includes the largest and flashiest representatives of this arachnid order. However, the relationships among its main lineages (families and superfamilies) and the timing of their origin are…

Cooper, N., Bond, A. L., Davis, J. L., Portela Miguez, R., Tomsett, L., & Helgen, K. M. (2019). Sex biases in bird and mammal natural history collections. Proceedings of the Royal Society B: Biological Sciences, 286(1913), 20192025. doi:10.1098/rspb.2019.2025 https://doi.org/10.1098/rspb.2019.2025

Natural history specimens are widely used across ecology, evolutionary biology and conservation. Although biological sex may influence all of these areas, it is often overlooked in large-scale studies using museum specimens. If collections are biased towards one sex, studies may not be representativ…

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…

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…

Scharff, N., Coddington, J. A., Blackledge, T. A., Agnarsson, I., Framenau, V. W., Szűts, T., … Dimitrov, D. (2019). Phylogeny of the orb‐weaving spider family Araneidae (Araneae: Araneoidea). Cladistics. doi:10.1111/cla.12382 https://doi.org/10.1111/cla.12382

We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S, COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 outgroups and 133 araneid ingroups representing the subfamilies Zygiellinae Simon, 1929, Nephilinae Simon, 1894, and the typ…

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…

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…

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…

Guevara, L., & Sánchez-Cordero, V. (2018). New records of a critically endangered shrew from Mexican cloud forests (Soricidae, Cryptotis nelsoni) and prospects for future field research. Biodiversity Data Journal, 6. doi:10.3897/bdj.6.e26667 https://doi.org/10.3897/BDJ.6.e26667

The Nelson´s small-eared shrew, Cryptotisnelsoni (Merriam, 1895), is a critically endangered species, endemic to cloud forests in Los Tuxtlas, a mountain range along the Gulf of Mexico coast. This species is only known from the type locality and its surroundings. Here we present new records that ext…
