Xue, T., S. R. Gadagkar, T. P. Albright, X. Yang, J. Li, C. Xia, J. Wu, and S. Yu. 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. 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…
de Oliveira, M. H. V., B. M. Torke, and T. E. Almeida. 2021. An inventory of the ferns and lycophytes of the Lower Tapajós River Basin in the Brazilian Amazon reveals collecting biases, sampling gaps, and previously undocumented diversity. Brittonia 73: 459–480. https://doi.org/10.1007/s12228-021-09668-7
Ferns and lycophytes are an excellent group for conservation and species distribution studies because they are closely related to environmental changes. In this study, we analyzed collection gaps, sampling biases, richness distribution, and the species conservation effectiveness of protected areas i…
Bontrager, M., T. Usui, J. A. Lee‐Yaw, D. N. Anstett, H. A. Branch, A. L. Hargreaves, C. D. Muir, and A. L. Angert. 2021. Adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion. Evolution 75: 1316–1333. 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…
Briscoe Runquist, R. D., T. A. Lake, and D. A. Moeller. 2021. Improving predictions of range expansion for invasive species using joint species distribution models and surrogate co‐occurring species. Journal of Biogeography 48: 1693–1705. https://doi.org/10.1111/jbi.14105
Aims: Species distribution models (SDMs) are often used to forecast potential distributions of important invasive or rare species. However, situations where models could be the most valuable ecologically or economically, such as for predicting invasion risk, often pose the greatest challenges to SDM…
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…
Yi, S., C.-P. Jun, K. Jo, H. Lee, M.-S. Kim, S. D. Lee, X. Cao, and J. Lim. 2020. Asynchronous multi-decadal time-scale series of biotic and abiotic responses to precipitation during the last 1300 years. Scientific Reports 10. https://doi.org/10.1038/s41598-020-74994-x

Chase, B. M., A. Boom, A. S. Carr, M. Chevalier, L. J. Quick, G. A. Verboom, and P. J. Reimer. 2019. Extreme hydroclimate response gradients within the western Cape Floristic region of South Africa since the Last Glacial Maximum. Quaternary Science Reviews 219: 297–307. https://doi.org/10.1016/j.quascirev.2019.07.006
The Cape Floristic Region (CFR) is one of the world's major biodiversity hotspots, and much work has gone into identifying the drivers of this diversity. Considered regionally in the context of Quaternary climate change, climate stability is generally accepted as being one of the major factors promo…
Chevalier, M., B. M. Chase, L. J. Quick, L. M. Dupont, and T. C. Johnson. 2020. Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology 49: 71–75. https://doi.org/10.1130/G47841.1
Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…
Hock, M., R. Hofmann, F. Essl, P. Pyšek, H. Bruelheide, and A. Erfmeier. 2020. Native distribution characteristics rather than functional traits explain preadaptation of invasive species to high‐UV‐B environments M. Carboni [ed.],. Diversity and Distributions 26: 1421–1438. https://doi.org/10.1111/ddi.13113
Aim: Alien species successfully colonize new ranges if they encounter favourable environmental conditions there and possess traits that match new challenges. Climate‐matching approaches comparing native and exotic ranges mostly consider temperature and precipitation niches of alien species, but have…
van Treuren, R., R. Hoekstra, R. Wehrens, and T. van Hintum. 2020. Effects of climate change on the distribution of crop wild relatives in the Netherlands in relation to conservation status and ecotope variation. Global Ecology and Conservation 23: e01054. https://doi.org/10.1016/j.gecco.2020.e01054
Crop wild relatives (CWR) are wild plant taxa that are genetically related to a cultivated species and are considered rich sources of useful traits for crop improvement. CWR are generally underrepresented in genebanks, while their survival in nature is not guaranteed. Inventories and risk analyses a…
