Xue, T., Gadagkar, S. R., Albright, T. P., Yang, X., Li, J., Xia, C., … Yu, S. (2021). Prioritizing conservation of biodiversity in an alpine region: Distribution pattern and conservation status of seed plants in the Qinghai-Tibetan Plateau. Global Ecology and Conservation, 32, e01885. doi:10.1016/j.gecco.2021.e01885 https://doi.org/10.1016/j.gecco.2021.e01885

The Qinghai-Tibetan Plateau (QTP) harbors abundant and diverse plant life owing to its high habitat heterogeneity. However, the distribution pattern of biodiversity hotspots and their conservation status remain unclear. Based on 148,283 high-resolution occurrence coordinates of 13,450 seed plants, w…

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…

Ethier, J. P., Fayard, A., Soroye, P., Choi, D., Mazerolle, M. J., & Trudeau, V. L. (2021). Life history traits and reproductive ecology of North American chorus frogs of the genus Pseudacris (Hylidae). Frontiers in Zoology, 18(1). doi:10.1186/s12983-021-00425-w https://doi.org/10.1186/s12983-021-00425-w

Amphibian biodiversity is declining globally, with over 40% of species being considered threatened to become extinct. Crucial to the success of conservation initiatives are a comprehensive understanding of life history and reproductive ecology of target species. Here we provide an overview of the Ps…

Baumbach, L., Warren, D. L., Yousefpour, R., & Hanewinkel, M. (2021). Climate change may induce connectivity loss and mountaintop extinction in Central American forests. Communications Biology, 4(1). doi:10.1038/s42003-021-02359-9 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., 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 …

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…

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…

Macedo-Santana, F., Flores-Tolentino, M., & Hernández-Guzmán, R. (2021). Diversity patterns of palms in Mexico using species distribution models. Écoscience, 1–11. doi:10.1080/11956860.2021.1888522 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., Guedes, T. B., Nogueira, C. de C., Passos, P., Sawaya, R. J., Prudente, A. L. C., … Antonelli, A. (2019). Museums and cradles of diversity are geographically coincident for narrowly distributed Neotropical snakes. Ecography, 43(2), 328–339. doi:10.1111/ecog.04815 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., Koutsodendris, A., Appel, E., Rösler, W., Reichgelt, T., Kaboth-Bahr, S., … Pross, J. (2021). Late Pliocene to early Pleistocene climate dynamics in western North America based on a new pollen record from paleo-Lake Idaho.

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…
