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…

Provost, K. L., Myers, E. A., & Smith, B. T. (2021). Community phylogeographic patterns reveal how a barrier filters and structures taxa in North American warm deserts. Journal of Biogeography. doi:10.1111/jbi.14115 https://doi.org/10.1111/jbi.14115

Aim: The study of biogeographic barriers is instrumental in understanding the evolution and distribution of taxa. With the increasing availability of empirical datasets, emergent patterns can be inferred from communities by synthesizing how barriers filter and structure populations across species. W…

Williamson, J. L., & Baumann, M. J. (2021). Evidence of Brood Parasitism and Quantification of Rangewide Overlap between the Olive Warbler and Brown-headed Cowbird. Western Birds, 52(1), 68–75. doi:10.21199/wb52.1.5 https://doi.org/10.21199/wb52.1.5

Brood parasitism is a fascinating natural history phenomenon that provides a window into the coevolution of antagonistic interactions. Many ecological and evolutionary aspects of brood parasitism remain unknown, and new hosts of brood parasites are still being discovered. We document the second inst…

Inman, R., Franklin, J., Esque, T., & Nussear, K. (2021). Comparing sample bias correction methods for species distribution modeling using virtual species. Ecosphere, 12(3). doi:10.1002/ecs2.3422 https://doi.org/10.1002/ecs2.3422

A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates. This assumption is rarely met when SDM practition…

Saldaña‐López, A., Vilà, M., Lloret, F., Manuel Herrera, J., & González‐Moreno, P. (2021). Assembly of species’ climatic niches of coastal communities does not shift after invasion. Journal of Vegetation Science, 32(2). doi:10.1111/jvs.12989 https://doi.org/10.1111/jvs.12989

Question: Do invasions by invasive plant species with contrasting trait profiles (Arctotheca calendula, Carpobrotus spp., Conyza bonariensis, and Opuntia dillenii) change the climatic niche of coastal plant communities? Location: Atlantic coastal habitats in Huelva (Spain). Methods: We identifi…

Hambuckers, A., de Harenne, S., Rocha Ledezma, E., Zúñiga Zeballos, L., & François, L. (2021). Predicting the Future Distribution of Ara rubrogenys, an Endemic Endangered Bird Species of the Andes, Taking into Account Trophic Interactions. Diversity, 13(2), 94. doi:10.3390/d13020094 https://doi.org/10.3390/d13020094

Species distribution models (SDMs) are commonly used with climate only to predict animal distribution changes. This approach however neglects the evolution of other components of the niche, like food resource availability. SDMs are also commonly used with plants. This also suffers limitations, notab…

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…
