Baumbach, L., D. L. Warren, R. Yousefpour, and M. Hanewinkel. 2021. Climate change may induce connectivity loss and mountaintop extinction in Central American forests. Communications Biology 4. https://doi.org/10.1038/s42003-021-02359-9

The tropical forests of Central America serve a pivotal role as biodiversity hotspots and provide ecosystem services securing human livelihood. However, climate change is expected to affect the species composition of forest ecosystems, lead to forest type transitions and trigger irrecoverable losses…

Miller, E. F., R. E. Green, A. Balmford, P. Maisano Delser, R. Beyer, M. Somveille, M. Leonardi, et al. 2021. Bayesian Skyline Plots disagree with range size changes based on Species Distribution Models for Holarctic birds. Molecular Ecology 30: 3993–4004. 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 …

Provost, K. L., E. A. Myers, and B. T. Smith. 2021. Community phylogeographic patterns reveal how a barrier filters and structures taxa in North American warm deserts. Journal of Biogeography 48: 1267–1283. 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…

Inman, R., J. Franklin, T. Esque, and K. Nussear. 2021. Comparing sample bias correction methods for species distribution modeling using virtual species. Ecosphere 12. 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…

Macedo-Santana, F., M. Flores-Tolentino, and R. Hernández-Guzmán. 2021. Diversity patterns of palms in Mexico using species distribution models. Écoscience 28: 137–147. https://doi.org/10.1080/11956860.2021.1888522

The family of palms (Arecaceae) comprises around 2,400 species distributed throughout the world, from which nearly 100 species have been reported to occur in Mexico. Given their importance and the lack of information about their distribution patterns in the country, we applied stacked species distri…

Azevedo, J. A. R., T. B. Guedes, C. de C. Nogueira, P. Passos, R. J. Sawaya, A. L. C. Prudente, F. E. Barbo, et al. 2019. Museums and cradles of diversity are geographically coincident for narrowly distributed Neotropical snakes. Ecography 43: 328–339. https://doi.org/10.1111/ecog.04815

Factors driving the spatial configuration of centres of endemism have long been a topic of broad interest and debate. Due to different eco‐evolutionary processes, these highly biodiverse areas may harbour different amounts of ancient and recently diverged organisms (paleo‐ and neo‐endemism, respecti…

Allstädt, F. J., A. Koutsodendris, E. Appel, W. Rösler, T. Reichgelt, S. Kaboth-Bahr, A. A. Prokopenko, and J. Pross. 2021. Late Pliocene to early Pleistocene climate dynamics in western North America based on a new pollen record from paleo-Lake Idaho. Palaeobiodiversity and Palaeoenvironments 101: 177–195. https://doi.org/10.1007/s12549-020-00460-1

Marked by the expansion of ice sheets in the high latitudes, the intensification of Northern Hemisphere glaciation across the Plio/Pleistocene transition at ~ 2.7 Ma represents a critical interval of late Neogene climate evolution. To date, the characteristics of climate change in North America duri…

Khosravifard, S., A. K. Skidmore, A. G. Toxopeus, and A. Niamir. 2020. Potential invasion range of raccoon in Iran under climate change. European Journal of Wildlife Research 66. https://doi.org/10.1007/s10344-020-01438-2

Growing global evidence demonstrates that not only the invasion of alien species has imposed serious threats to native biodiversity, but it also threatens health and economics. The raccoon (Procyon lotor), medium-sized mammal, native to North America, as a result of escapes or deliberate introductio…

Pérez-Arteaga, A., S. A. Mora-Sánchez, S. S. Zalapa, and S. Guerrero-Vázquez. 2020. Photographic Confirmation of Crested Guan (Penelope purpurascens) from a Relict Maple Forest in Western Mexico. Western North American Naturalist 80. https://doi.org/10.3398/064.080.0314

The Crested Guan (Penelope purpurascens) is globally decreasing and endangered in Mexico. Here we report new records (8 adults and 2 juveniles) from a protected relict maple forest (critically endangered Acer binzayedii) in Parque Estatal Bosque de Arce (PEBA), Talpa de Allende, Jalisco, Mexico. Our…

Ramírez‐Albores, J. E., D. A. Prieto‐Torres, A. Gordillo‐Martínez, L. E. Sánchez‐Ramos, and A. G. Navarro‐Sigüenza. 2020. Insights for protection of high species richness areas for the conservation of Mesoamerican endemic birds A. Hughes [ed.],. Diversity and Distributions 27: 18–33. https://doi.org/10.1111/ddi.13153

Aim: To assess the representativeness values of Mesoamerican endemic birds within the current network of protected areas (PAs) to determine high‐priority and complementary conservation areas to maximize the long‐term protection of species. Location: From central Mexico to southern Panama. Methods:…
