Smith, A. L., Hodkinson, T. R., Villellas, J., Catford, J. A., Csergő, A. M., Blomberg, S. P., … Buckley, Y. M. (2020). Global gene flow releases invasive plants from environmental constraints on genetic diversity. Proceedings of the National Academy of Sciences, 117(8), 4218–4227. doi:10.1073/pnas.1915848117 https://doi.org/10.1073/pnas.1915848117

When plants establish outside their native range, their ability to adapt to the new environment is influenced by both demography and dispersal. However, the relative importance of these two factors is poorly understood. To quantify the influence of demography and dispersal on patterns of genetic div…

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…

Eckert, S., Hamad, A., Kilawe, C. J., Linders, T. E. W., Ng, W., Mbaabu, P. R., … Schaffner, U. (2020). Niche change analysis as a tool to inform management of two invasive species in Eastern Africa. Ecosphere, 11(2). doi:10.1002/ecs2.2987 https://doi.org/10.1002/ecs2.2987

Significant progress has been made in providing guidelines and recommendations for assessing the ecological niche, stage of invasion, and probability of invasive alien plant species (IAPS) potential distribution in space and time. We followed these recommendations by developing and comparing ordinat…

Teshera-Levye, J., Miles, B., Terwilliger, V., Lovelock, C. E., & Cavender-Bares, J. (2019). Drivers of habitat partitioning among three Quercus species along a hydrologic gradient. Tree Physiology. doi:10.1093/treephys/tpz112 https://doi.org/10.1093/treephys/tpz112

A critical process that allows multiple, similar species to coexist in an ecological community is their ability to partition local habitat gradients. The mechanisms that underlie this separation at local scales may include niche differences associated with their biogeographic history, differences in…

Zizka, A., Azevedo, J., Leme, E., Neves, B., Costa, A. F., Caceres, D., & Zizka, G. (2019). Biogeography and conservation status of the pineapple family (Bromeliaceae). Diversity and Distributions. doi:10.1111/ddi.13004 https://doi.org/10.1111/ddi.13004

Aim: To provide distribution information and preliminary conservation assessments for all species of the pineapple family (Bromeliaceae), one of the most diverse and ecologically important plant groups of the American tropics—a global biodiversity hotspot. Furthermore, we aim to analyse patterns of …

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…

Lebeda, A., Křístková, E., Kitner, M., Majeský, Ľ., Doležalová, I., Khoury, C. K., … Sosa, C. C. (2019). Research Gaps and Challenges in the Conservation and Use of North American Wild Lettuce Germplasm. Crop Science, 0(0), 0. doi:10.2135/cropsci2019.05.0350 https://doi.org/10.2135/cropsci2019.05.0350

The North American crop wild relatives (CWR) of lettuce (Lactuca L.) represent an underexplored pool of genetic diversity of potential value to breeding programs. The 10 species belong to three different groups: a native clade including at least six allotetraploid species [L. biennis (Moench) Fernal…

Afonin, A. N., Fedorova, Y. A., & Li, Y. S. (2019). Characterization of the Occurrence and Abundance of the Common Ragweed (Ambrosia artemisiifolia L.) with Regard to Assessment of Its Expansion Potential in European Russia. Russian Journal of Biological Invasions, 10(3), 220–226. doi:10.1134/s2075111719030032 https://doi.org/10.1134/S2075111719030032

A field study of common ragweed (Ambrosia artemisiifolia L.) in European Russia provided information on the occurrence and abundance of the species and enabled a prediction of the possible boundaries of species naturalization. As a result, the understanding of the ecological limits of common ragweed…

Mezghani, N., Khoury, C. K., Carver, D., Achicanoy, H. A., Simon, P., Flores, F. M., & Spooner, D. (2019). Distributions and Conservation Status of Carrot Wild Relatives in Tunisia: A Case Study in the Western Mediterranean Basin. Crop Science, 0(0), 0. doi:10.2135/cropsci2019.05.0333 https://doi.org/10.2135/cropsci2019.05.0333

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant species, are sources of valuable genetic resources for crop improvement. Persisting gaps in knowledge of taxonomy, distributions, and characterization for traits of interest constrain their expanded use in plan…

Marconi, L., & Armengot, L. (2020). Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment, 287, 106664. doi:10.1016/j.agee.2019.106664 https://doi.org/10.1016/j.agee.2019.106664

In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…
