Ramirez‐Villegas, J., Khoury, C. K., Achicanoy, H. A., Mendez, A. C., Diaz, M. V., Sosa, C. C., … Guarino, L. (2020). A gap analysis modelling framework to prioritize collecting for ex situ conservation of crop landraces. Diversity and Distributions. doi:10.1111/ddi.13046 https://doi.org/10.1111/ddi.13046

Aim: The conservation and effective use of crop genetic diversity are crucial to overcome challenges related to human nutrition and agricultural sustainability. Farmers’ traditional varieties (“landraces”) are major sources of genetic variation. The degree of representation of crop landrace diversit…

De Siracusa, P. C., Gadelha, L. M. R., & Ziviani, A. (2020). New perspectives on analysing data from biological collections based on social network analytics. Scientific Reports, 10(1). doi:10.1038/s41598-020-60134-y https://doi.org/10.1038/s41598-020-60134-y

Biological collections have been historically regarded as fundamental sources of scientific information on biodiversity. They are commonly associated with a variety of biases, which must be characterized and mitigated before data can be consumed. In this work, we are motivated by taxonomic and colle…

Carrasco, J., Price, V., Tulloch, V., & Mills, M. (2020). Selecting priority areas for the conservation of endemic trees species and their ecosystems in Madagascar considering both conservation value and vulnerability to human pressure. Biodiversity and Conservation. doi:10.1007/s10531-020-01947-1 https://doi.org/10.1007/s10531-020-01947-1

Madagascar is one of the most biodiverse countries in Africa, due to its level of endemism and species diversity. However, the pressure of human activities threatens the last patches of natural vegetation in the country and conservation decisions are undertaken with limited data availability. In thi…

Asase, A., Sainge, M. N., Radji, R. A., Ugbogu, O. A., & Peterson, A. T. (2020). A new model for efficient, need‐driven progress in generating primary biodiversity information resources. Applications in Plant Sciences, 8(1). doi:10.1002/aps3.11318 https://doi.org/10.1002/aps3.11318

Premise: The field of biodiversity informatics has developed rapidly in recent years, with broad availability of large‐scale information resources. However, online biodiversity information is biased spatially as a result of slow and uneven capture and digitization of existing data resources. The Wes…

Léveillé-Bourret, É., Chen, B.-H., Garon-Labrecque, M.-È., Ford, B. A., & Starr, J. R. (2019). RAD sequencing resolves the phylogeny, taxonomy and biogeography of Trichophoreae despite a rapid recent radiation (Cyperaceae). Molecular Phylogenetics and Evolution, 106727. doi:10.1016/j.ympev.2019.106727 https://doi.org/10.1016/j.ympev.2019.106727

Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial …

Mienna, I. M., Speed, J. D. M., Bendiksby, M., Thornhill, A. H., Mishler, B. D., & Martin, M. D. (2019). Differential patterns of floristic phylogenetic diversity across a post‐glacial landscape. Journal of Biogeography. doi:10.1111/jbi.13789 https://doi.org/10.1111/jbi.13789

Aim: In this study, we explored spatial patterns of phylogenetic diversity (PD) and endemism in the flora of Norway and tested hypothesized post‐glacial environmental drivers of PD, including temperature, precipitation, edaphic factors and time since glacial retreat. Location: Norway. Taxon: Vascula…

Khoury, C. K., Carver, D., Kates, H. R., Achicanoy, H. A., Zonneveld, M., Thomas, E., … Greene, S. L. (2019). Distributions, conservation status, and abiotic stress tolerance potential of wild cucurbits ( Cucurbita L.). PLANTS, PEOPLE, PLANET. doi:10.1002/ppp3.10085 https://doi.org/10.1002/ppp3.10085

Crop wild relatives—wild species closely related to cultivated plants—are valuable genetic resources for crop improvement, but gaps in knowledge constrain their conservation and limit their further use. We develop new information on the distributions, potential breeding value, and conservation statu…

Kass, J. M., Anderson, R. P., Espinosa‐Lucas, A., Juárez‐Jaimes, V., Martínez‐Salas, E., Botello, F., … Sánchez‐Cordero, V. (2019). Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in Mexico. Ecography. doi:10.1111/ecog.04886 https://doi.org/10.1111/ecog.04886

Although long‐standing theory suggests that biotic variables are only relevant at local scales for explaining the patterns of species’ distributions, recent studies have demonstrated improvements to species distribution models (SDMs) by incorporating predictor variables informed by biotic interactio…

Berg, C. S., Brown, J. L., & Weber, J. J. (2019). An examination of climate‐driven flowering‐time shifts at large spatial scales over 153 years in a common weedy annual. American Journal of Botany. doi:10.1002/ajb2.1381 https://doi.org/10.1002/ajb2.1381

Premise: Understanding species’ responses to climate change is a critical challenge facing biologists today. Though many species are widespread, few studies of climate‐driven shifts in flowering time have examined large continuous spatial scales for individual species. And even fewer studies have ex…

Rodríguez-Merino, A., Fernández-Zamudio, R., García-Murillo, P., & Muñoz, J. (2019). Climatic Niche Shift during Azolla filiculoides Invasion and Its Potential Distribution under Future Scenarios. Plants, 8(10), 424. doi:10.3390/plants8100424 https://doi.org/10.3390/plants8100424

In order to prevent future biological invasions, it is crucial to know non-native species distributions. We evaluated the potential global distribution of Azolla filiculoides, a free-floating macrophyte native to the Americas by using species distribution models and niche equivalency tests to analyz…
