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…

Pirie, M. D., Kandziora, M., Nürk, N. M., Le Maitre, N. C., Mugrabi de Kuppler, A., Gehrke, B., … Bellstedt, D. U. (2019). Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica. BMC Evolutionary Biology, 19(1). doi:10.1186/s12862-019-1545-6 https://doi.org/10.1186/s12862-019-1545-6

Background: The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted interplay between geographical distance and ecological suitability of source and sink areas. Here, we test the influence of these factors on the dispersal history of the floweri…

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…

Gomes, S. I. F., van Bodegom, P. M., Merckx, V. S. F. T., & Soudzilovskaia, N. A. (2019). Global distribution patterns of mycoheterotrophy. Global Ecology and Biogeography. doi:10.1111/geb.12920 https://doi.org/10.1111/geb.12920

Aim: Mycoheterotrophy is a mode of life where plants cheat the mycorrhizal symbiosis, receiving carbon via their fungal partners. Despite being widespread, mycoheterotrophic plants are locally rare, hampering the understanding of their global environmental drivers. Here, we explore global environmen…

Wan, J.-Z., Zhang, Z.-X., & Wang, C.-J. (2019). Effects of ecoregional vulnerability on habitat suitability of invasive alien plants: an assessment using 13 species on a global scale. Environmental Earth Sciences, 78(5). doi:10.1007/s12665-019-8186-3 https://doi.org/10.1007/s12665-019-8186-3

The development of new hypotheses can promote the explanation of mechanisms on plant invasion across different scales. We tested the hypothesis that ecoregional vulnerability can affect habitat suitability of invasive alien plants (IAPs) in non-native ranges. We used 13 IAPs, distributed around the …

Karger, D. N., Kessler, M., Conrad, O., Weigelt, P., Kreft, H., König, C., & Zimmermann, N. E. (2019). Why tree lines are lower on islands-Climatic and biogeographic effects hold the answer. Global Ecology and Biogeography. doi:10.1111/geb.12897 https://doi.org/10.1111/geb.12897

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…

Sheppard, C. S., & Schurr, F. M. (2018). Biotic resistance or introduction bias? Immigrant plant performance decreases with residence times over millennia. Global Ecology and Biogeography. doi:10.1111/geb.12844 https://doi.org/10.1111/geb.12844

Aim: Invasions are dynamic processes. Invasive spread causes the geographical range size of alien species to increase with residence time. However, with time native competitors and antagonists can adapt to invaders. This build‐up of biotic resistance may eventually limit the invader’s performance an…

Wan, J.-Z., Zhang, Z.-X., & Wang, C.-J. (2018). Identifying potential distributions of 10 invasive alien trees: implications for conservation management of protected areas. Environmental Monitoring and Assessment, 190(12). doi:10.1007/s10661-018-7104-6 https://doi.org/10.1007/s10661-018-7104-6

Tree invasion has the potential to negatively affect biodiversity and ecosystems, with invasive alien trees (IATs) expanding widely in protected areas (PAs) across different habitats. Thus, the effectiveness of PAs might be reduced. Investigation of the distributions of IAT is urgently required to i…
