Phylogeography and morphometric variation in the Cinnamon Hummingbird complex: Amazilia rutila (Aves: Trochilidae). Avian Research, 12(1). doi:10.1186/s40657-021-00295-0 https://doi.org/10.1186/s40657-021-00295-0

Background The Mesoamerican dominion is a biogeographic area of great interest due to its complex topography and distinctive climatic history. This area has a large diversity of habitats, including tropical deciduous forests, which house a large number of endemic species. Here, we assess phylogeogra…

Contreras-Martínez, S., Rosas-Espinoza, V. C., Santiago-Pérez, A. L., Carlos-Gómez, J. A., Salas-Ruiz, A. N., & Cárdenas-Hernández, O. G. (2021). Southern distribution and evidence of migration in the Eared Quetzal (Euptilotis neoxenus) in west-central Jalisco, Mexico. The Wilson Journal of Ornithology, 132(4). doi:10.1676/1559-4491-132.4.991 https://doi.org/10.1676/1559-4491-132.4.991

The Eared Quetzal (Euptilotis neoxenus) is a Mexican endemic. It occurs from northwestern to west-central Mexico. It is considered threatened in Mexican environmental law. The lack of knowledge about its ecology and distribution during the nonbreeding season motivated our investigation. While invent…

Prieto-Torres, D. A., Nuñez Rosas, L. E., Remolina Figueroa, D., & Arizmendi, M. del C. (2021). Most Mexican hummingbirds lose under climate and land-use change: Long-term conservation implications. Perspectives in Ecology and Conservation. doi:10.1016/j.pecon.2021.07.001 https://doi.org/10.1016/j.pecon.2021.07.001

Hummingbirds are one of the most threatened bird groups in the world. However, the extent to which global climate change (GCC) and habitat loss compromise their conservation status remains unclear. Herein, we proposed to: (1) assess how predicted GCC impacts the distribution of non-migrant hummingbi…

Bemmels, J. B., Bramwell, A. C., Anderson, S. A. S., Luzuriaga‐Aveiga, V. E., Mikkelsen, E. K., & Weir, J. T. (2021). Geographic contact drives increased reproductive isolation in two cryptic Empidonax flycatchers. Molecular Ecology. doi:10.1111/mec.16105 https://doi.org/10.1111/mec.16105

Geographic contact between sister lineages often occurs near the final stages of speciation, but its role in speciation's completion remains debated. Reproductive isolation may be essentially complete prior to secondary contact. Alternatively, costly interactions between partially reproductively iso…

Vásquez-Aguilar, A. A., Ornelas, J. F., Rodríguez-Gómez, F., & Cristina MacSwiney G., M. (2021). Modeling Future Potential Distribution of Buff-Bellied Hummingbird (Amazilia yucatanensis) Under Climate Change: Species vs. Subspecies. Tropical Conservation Science, 25, 194008292110308. doi:10.1177/19400829211030834 https://doi.org/10.1177/19400829211030834

Global climate change is associated with changes in precipitation patterns and an increase in extreme weather events, which might shift the geographic distribution of species. Despite the importance of this topic, information is lacking for many species, particularly tropical birds. Here, we develop…

Miller, E. F., Green, R. E., Balmford, A., Maisano Delser, P., Beyer, R., Somveille, M., … Manica, A. (2021). Bayesian Skyline Plots disagree with range size changes based on Species Distribution Models for Holarctic birds. Molecular Ecology. doi:10.1111/mec.16032 https://doi.org/10.1111/mec.16032

During the Quaternary, large climate oscillations impacted the distribution and demography of species globally. Two approaches have played a major role in reconstructing changes through time: Bayesian Skyline Plots (BSPs), which reconstruct population fluctuations based on genetic data, and Species …

Soifer, L. G., Donovan, S. K., Brentjens, E. T., & Bratt, A. R. (2021). Piecing together cities to support bird diversity: Development and forest edge density affect bird richness in urban environments. Landscape and Urban Planning, 213, 104122. doi:10.1016/j.landurbplan.2021.104122 https://doi.org/10.1016/j.landurbplan.2021.104122

Urban areas are quickly expanding in the southeastern United States with varying effects on biodiversity. Maintaining bird richness in cities is essential for conserving ecosystem function. In this study, we determined the relative importance of landscape composition and configuration on urban avian…

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…

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…

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…
