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…

Bontrager, M., Usui, T., Lee‐Yaw, J. A., Anstett, D. N., Branch, H. A., Hargreaves, A. L., … Angert, A. L. (2021). Adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion. Evolution. doi:10.1111/evo.14231 https://doi.org/10.1111/evo.14231

Every species experiences limits to its geographic distribution. Some evolutionary models predict that populations at range edges are less well‐adapted to their local environments due to drift, expansion load, or swamping gene flow from the range interior. Alternatively, populations near range edges…

Mazijk, R., Cramer, M. D., & Verboom, G. A. (2021). Environmental heterogeneity explains contrasting plant species richness between the South African Cape and southwestern Australia. Journal of Biogeography. doi:10.1111/jbi.14118 https://doi.org/10.1111/jbi.14118

Aim: Given the importance of environmental heterogeneity as a driver of species richness through its effects on species diversification and coexistence, we asked whether the dramatic difference in species richness per unit area between two similar Mediterranean‐type biodiversity hotspots is explaine…

Diao, Y., Wang, J., Yang, F., Wu, W., Zhou, J., & Wu, R. (2021). Identifying optimized on-the-ground priority areas for species conservation in a global biodiversity hotspot. Journal of Environmental Management, 290, 112630. doi:10.1016/j.jenvman.2021.112630 https://doi.org/10.1016/j.jenvman.2021.112630

Threatened species are inadequately represented within protected areas (PAs) across the globe. Species conservation planning may be improved by using public species-occurrence databases, but empirical evidence is limited of how that may be accomplished at local scales. We used the Three Parallel Riv…

Ruiz, D. P., Pujana, R. R., & Brea, M. (2021). Early Miocene paleoclimate in southern Patagonia inferred from fossil woods. Review of Palaeobotany and Palynology, 290, 104429. doi:10.1016/j.revpalbo.2021.104429 https://doi.org/10.1016/j.revpalbo.2021.104429

Patagonia has a rich record of fossil woods that are a unique data store of paleoclimatic information. We studied the wood flora recovered from the Río Leona Formation (early Miocene) of southern Patagonia near El Calafate and Río Turbio localities, Santa Cruz Province, Argentina. The fossil wood as…

Zhang, Y., Chen, J., & Sun, H. (2021). Alpine speciation and morphological innovations: revelations from a species-rich genus in the Northern Hemisphere. AoB PLANTS. doi:10.1093/aobpla/plab018 https://doi.org/10.1093/aobpla/plab018

Background and Aims A large number of studies have attempted to determine the mechanisms driving plant diversity and distribution on a global scale, but the diverse and endemic alpine herbs found in harsh environments, showing adaptive evolution, require more studies. Methods Here, we selected 466 s…

Dellinger, A. S., Pérez‐Barrales, R., Michelangeli, F. A., Penneys, D. S., Fernández‐Fernández, D. M., & Schönenberger, J. (2021). Low bee visitation rates explain pollinator shifts to vertebrates in tropical mountains. New Phytologist. doi:10.1111/nph.17390 https://doi.org/10.1111/nph.17390

Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central for the evolution and diversification of angiosperms, w…

Rock, B. M., & Daru, B. H. (2021). Impediments to Understanding Seagrasses’ Response to Global Change. Frontiers in Marine Science, 8. doi:10.3389/fmars.2021.608867 https://doi.org/10.3389/fmars.2021.608867

Uncertainties from sampling biases present challenges to ecologists and evolutionary biologists in understanding species sensitivity to anthropogenic climate change. Here, we synthesize possible impediments that can constrain research to assess present and future seagrass response from climate chang…

Bogotá‐Ángel, G., Huang, H., Jardine, P. E., Chazot, N., Salamanca, S., Banks, H., … Hoorn, C. (2021). Climate and geological change as drivers of Mauritiinae palm biogeography. Journal of Biogeography. doi:10.1111/jbi.14098 https://doi.org/10.1111/jbi.14098

Aim: Forest composition and distribution are determined by a myriad of factors, including climate. As models of tropical rain forest, palms are often used as indicator taxa, particularly the Mauritiinae. We question, what characterizes the Mauritiinae pollen in the global fossil record? And when did…

Tribble, C. M., Martínez‐Gómez, J., Howard, C. C., Males, J., Sosa, V., Sessa, E. B., … Specht, C. D. (2021). Get the shovel: morphological and evolutionary complexities of belowground organs in geophytes. American Journal of Botany. doi:10.1002/ajb2.1623 https://doi.org/10.1002/ajb2.1623

Herbaceous plants collectively known as geophytes, which regrow from belowground buds, are distributed around the globe and throughout the land plant tree of life. The geophytic habit is an evolutionarily and ecologically important growth form in plants, permitting novel life history strategies, ena…
