Beaulieu, W. T., Panaccione, D. G., Quach, Q. N., Smoot, K. L., & Clay, K. (2021). Diversification of ergot alkaloids and heritable fungal symbionts in morning glories. Communications Biology, 4(1). doi:10.1038/s42003-021-02870-z https://doi.org/10.1038/s42003-021-02870-z

Heritable microorganisms play critical roles in life cycles of many macro-organisms but their prevalence and functional roles are unknown for most plants. Bioactive ergot alkaloids produced by heritable Periglandula fungi occur in some morning glories (Convolvulaceae), similar to ergot alkaloids in …

Vasconcelos, T., Boyko, J. D., & Beaulieu, J. M. (2021). Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. doi:10.1111/jbi.14292 https://doi.org/10.1111/jbi.14292

Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…

Alban, D. M., Biersma, E. M., Kadereit, J. W., & Dillenberger, M. S. (2021). Colonization of the Southern Hemisphere by Sagina and Colobanthus (Caryophyllaceae). Plant Systematics and Evolution, 308(1). doi:10.1007/s00606-021-01793-w https://doi.org/10.1007/s00606-021-01793-w

Colobanthus (23 species) and Sagina (30–33 species) together are sister to Facchinia. Whereas Facchinia is distributed in western Eurasia, Colobanthus is almost exclusively distributed in the Southern Hemisphere, and Sagina is distributed in both hemispheres with the highest species diversity in wes…

Scherbinski, J. J., Piaggio, A. J., & Bean, W. T. (2021). MIXED EVIDENCE FOR NICHE CONSERVATISM IN MOUNTAIN BEAVER (APLODONTIA RUFA) LINEAGES. Northwestern Naturalist, 102(3). doi:10.1898/1051-1733-102.3.196 https://doi.org/10.1898/1051-1733-102.3.196

Range shifts in response to past climatic changes have been documented in a variety of species and have often resulted in the isolation of relict populations. Understanding how these isolated populations develop local adaptations or maintain their historic climatic niche is crucial to creating effec…

Solovyeva, D., Bysykatova-Harmey, I., Vartanyan, S. L., Kondratyev, A., & Huettmann, F. (2021). Modeling Eastern Russian High Arctic Geese (Anser fabalis, A. albifrons) during moult and brood rearing in the “New Digital Arctic.” Scientific Reports, 11(1). doi:10.1038/s41598-021-01595-7 https://doi.org/10.1038/s41598-021-01595-7

Many polar species and habitats are now affected by man-made global climate change and underlying infrastructure. These anthropogenic forces have resulted in clear implications and many significant changes in the arctic, leading to the emergence of new climate, habitats and other issues including di…

Cardador, L., Abellán, P., & Blackburn, T. M. (2021). Incorporating phylogeographic information in alien bird distribution models increases geographic extent but not accuracy of predictions. Biological Invasions. doi:10.1007/s10530-021-02673-7 https://doi.org/10.1007/s10530-021-02673-7

Species distribution models (SDM) have been proposed as valuable first screening tools for predicting species responses to new environmental conditions. SDMs are usually conducted at the species level, assuming that species-environment relationships are a species-specific feature that do not evolve …

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…

López‐Delgado, J., & Meirmans, P. G. (2021). History or demography? Determining the drivers of genetic variation in North American plants. Molecular Ecology. doi:10.1111/mec.16230 https://doi.org/10.1111/mec.16230

Understanding the impact of historical and demographic processes on genetic variation is essential for devising conservation strategies and predicting responses to climate change. Recolonization after Pleistocene glaciations is expected to leave distinct genetic signatures, characterised by lower ge…

Onditi, K. O., Li, X., Song, W., Li, Q., Musila, S., Mathenge, J., … Jiang, X. (2021). The management effectiveness of protected areas in Kenya. Biodiversity and Conservation. doi:10.1007/s10531-021-02276-7 https://doi.org/10.1007/s10531-021-02276-7

Merely designating new and/or expanding existing protected areas (PAs) does not guarantee the protection of critical ecosystems and species. The management of PAs must be effective to sustain meaningful conservational outcomes. We inferred the management effectiveness of PAs in Kenya based on the re…
