Zhang, N., Liao, Z., Wu, S., Nobis, M. P., Wang, J., & Wu, N. (2021). Impact of climate change on wheat security through an alternate host of stripe rust. Food and Energy Security. doi:10.1002/fes3.356 https://doi.org/10.1002/fes3.356

In the 21st century, stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is still the most devastating disease of wheat globally. Despite the critical roles of the alternate host plants, the Berberis species, in the sexual reproduction and spread of Pst, the climate change impacts on t…

Cui, N., Chen, T., Liao, B., Xu, J., & Li, X. (2021). The biology of medicinal resource substitution in Salvia. Chinese Medicine, 16(1). doi:10.1186/s13020-021-00548-6 https://doi.org/10.1186/s13020-021-00548-6

Background The decrease of wild reserves and the sharp increase of market demand have led to resource substitution, but it is still not clear how to discover medicinal alternative resources. Here we reveal the biology of medicinal resource substitution in the case of Salvia. Methods A hypothesis was…

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 …

Jourdan, J., Riesch, R., & Cunze, S. (2021). Off to new shores: Climate niche expansion in invasive mosquitofish ( Gambusia spp.). Ecology and Evolution, 11(24), 18369–18400. doi:10.1002/ece3.8427 https://doi.org/10.1002/ece3.8427

Aim: Formerly introduced for their presumed value in controlling mosquito-borne diseases, the two mosquitofish Gambusia affinis and G. holbrooki (Poeciliidae) are now among the world's most widespread invasive alien species, negatively impacting aquatic ecosystems around the world. These inconspicuo…

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…

Roberts, J., & Florentine, S. (2021). A review of the biology, distribution patterns and management of the invasive species Amaranthus palmeri S. Watson (Palmer amaranth): Current and future management challenges. Weed Research. doi:10.1111/wre.12520 https://doi.org/10.1111/wre.12520

Amaranthus palmeri S. Watson (Palmer amaranth) is an invasive agricultural weed that has quickly risen from a state of relative obscurity to now being globally regarded as one of the most economically destructive and difficult to manage weed species. It is now found in more than 45 countries where i…

Wham, B. E., Rahman, S. R., Martinez‐Correa, M., & Hines, H. M. (2021). Mito‐nuclear discordance at a mimicry color transition zone in bumble bee Bombus melanopygus. Ecology and Evolution, 11(24), 18151–18168. doi:10.1002/ece3.8412 https://doi.org/10.1002/ece3.8412

As hybrid zones exhibit selective patterns of gene flow between otherwise distinct lineages, they can be especially valuable for informing processes of microevolution and speciation. The bumble bee, Bombus melanopygus, displays two distinct color forms generated by Müllerian mimicry: a northern “Roc…

The distribution and knowledge on the Mediterranean mantid Iris oratoria (Linnaeus, 1785) is here updated. Despite is beautiful appearance and presence in the social media, the scientific knowledge on its real distribution is poor and incomplete and this may affect its conservation at local scales. …

Lewthwaite, J. M. M., & Mooers, A. Ø. (2021). Geographical homogenization but little net change in the local richness of Canadian butterflies. Global Ecology and Biogeography. doi:10.1111/geb.13426 https://doi.org/10.1111/geb.13426

Aim: Recent studies have found that local-scale plots measured through time exhibit marked variation in the change in species richness. However, the overall effect often reveals no net change. Most studies to date have been agnostic about the identities of the species lost/gained and about the proce…

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…
