Williamson, J. L., & Witt, C. C. (2021). Elevational niche-shift migration: Why the degree of elevational change matters for the ecology, evolution, and physiology of migratory birds. Ornithology, 138(2). doi:10.1093/ornithology/ukaa087 https://doi.org/10.1093/ornithology/ukaa087

Elevational migration can be defined as roundtrip seasonal movement that involves upward and downward shifts in elevation. These shifts incur physiological challenges that are proportional to the degree of elevational change. Larger shifts in elevation correspond to larger shifts in partial pressure…

Wieringa, J. G., Carstens, B. C., & Gibbs, H. L. (2021). Predicting migration routes for three species of migratory bats using species distribution models. PeerJ, 9, e11177. doi:10.7717/peerj.11177 https://doi.org/10.7717/peerj.11177

Understanding seasonal variation in the distribution and movement patterns of migratory species is essential to monitoring and conservation efforts. While there are many species of migratory bats in North America, little is known about their seasonal movements. In terms of conservation, this is impo…

Cruz, J. A., Prado, J. L., & Arroyo-Cabrales, J. (2021). The mutual ecogeographical range and paleoclimatic reconstruction during the Late Pleistocene-Holocene in the Pampas (Argentina) using meso and microvertebrate fossils. The Holocene, 095968362199465. doi:10.1177/0959683621994652 https://doi.org/10.1177/0959683621994652

The Pampas of Argentina is a large grassland ecosystem located in the oriental region southern of South America. As a study case, we present the results of the paleoclimatic analysis of the Tixi Cave site. This is a paleontological and archeological locality that shows a long chronologic sequence, w…

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…

Le Sage, E. H., Duncan, S. I., Seaborn, T., Cundiff, J., Rissler, L. J., & Crespi, E. J. (2021). Ecological adaptation drives wood frog population divergence in life history traits. Heredity. doi:10.1038/s41437-021-00409-w https://doi.org/10.1038/s41437-021-00409-w

Phenotypic variation among populations is thought to be generated from spatial heterogeneity in environments that exert selection pressures that overcome the effects of gene flow and genetic drift. Here, we tested for evidence of isolation by distance or by ecology (i.e., ecological adaptation) to g…

Andersen, D., Borzée, A., & Jang, Y. (2021). Predicting global climatic suitability for the four most invasive anuran species using ecological niche factor analysis. Global Ecology and Conservation, 25, e01433. doi:10.1016/j.gecco.2020.e01433 https://doi.org/10.1016/j.gecco.2020.e01433

Invasive species have a massive impact on their environment and predicting geographical zones at risk of invasion is paramount to the control of further invasions. Invasive anurans are particularly detrimental to native amphibian species, other vertebrates, and even aquaculture through competition, …

Clements, S. L., Powell, E. A., Mothes, C. C., & Searcy, C. A. (2020). Assessing the conservation risk of Sphaerodactylus notatus, the U.S. herpetofaunal species most vulnerable to sea level rise. Biodiversity and Conservation. doi:10.1007/s10531-020-02080-9 https://doi.org/10.1007/s10531-020-02080-9

While climate change and sea level rise threaten species across the globe, species in low-lying coastal regions, such as South Florida, are projected to face particularly severe threats. One such species is the Florida reef gecko (Sphaerodactylus notatus), the only gecko native to the eastern U.S., …

Ortiz, A. M. D., & Torres, J. N. V. (2020). Assessing the Impacts of Agriculture and Its Trade on Philippine Biodiversity. Land, 9(11), 403. doi:10.3390/land9110403 https://doi.org/10.3390/land9110403

Many Philippine species are at risk of extinction because of habitat loss and degradation driven by agricultural land use and land-use change. The Philippines is one of the world’s primary banana and pineapple producers. The input-intensive style of plantation agriculture for these typically exporte…

Seaborn, T., Goldberg, C. S., & Crespi, E. J. (2020). Drivers of distributions and niches of North American cold‐adapted amphibians: evaluating both climate and land use. Ecological Applications. doi:10.1002/eap.2236 https://doi.org/10.1002/eap.2236

Species distribution estimates are often used to understand the niche of a species; however, these are often based solely on climatic predictors. When the influences of biotic factors are ignored, erroneous inferences about range and niche may be made. We aimed to integrate climate data with a uniqu…

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…
