Location: The study covered the potential native ranges of currently recognized wild Capsicum taxa, throughout the Americas. Methods: We modelled the po…

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…

Hawthorne, W. D., & Marshall, C. A. M. (2019). Rapid Botanic Survey, Bioquality and improving botanical inventory in the tropics by integrating across spatial scales. Gardens’ Bulletin Singapore, 71(suppl.2), 315–333. doi:10.26492/gbs71(suppl.2).2019-21 https://doi.org/10.26492/gbs71(suppl.2).2019-21

We review the Rapid Botanic Survey method (RBS), in the context of botanical recording to date. The concept of bioquality, a biodiversity value respecting global rarity, is summarised. Bioquality assessment involves the Star system for categorising species by global rarity; and a Genetic Heat Index …

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.…

Folk, R. A., Stubbs, R. L., Mort, M. E., Cellinese, N., Allen, J. M., Soltis, P. S., … Guralnick, R. P. (2019). Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences, 116(22), 10874–10882. doi:10.1073/pnas.1817999116 https://doi.org/10.1073/pnas.1817999116

Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. Such density-dependent models imply tight linkages between diversification and…

Ramos, R. S., Kumar, L., Shabani, F., & Picanço, M. C. (2019). Risk of spread of tomato yellow leaf curl virus (TYLCV) in tomato crops under various climate change scenarios. Agricultural Systems, 173, 524–535. doi:10.1016/j.agsy.2019.03.020 https://doi.org/10.1016/j.agsy.2019.03.020

Species distribution models (SDMs) are valuable for the information they provide to reduce the potential negative effects of climatic factors on agricultural production systems. Such information may be used to prevent the entry and spread of invasive species in new areas, as well as to monitor regio…

Gamisch, A., & Comes, H. P. (2019). Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae). BMC Evolutionary Biology, 19(1). doi:10.1186/s12862-019-1416-1 https://doi.org/10.1186/s12862-019-1416-1

Background: Tropical rainforests (TRFs) harbour almost half of the world’s vascular plant species diversity while covering only about 6–7% of land. However, why species richness varies amongst the Earth’s major TRF regions remains poorly understood. Here we investigate the evolutionary processes sha…

Panchen, Z. A., Doubt, J., Kharouba, H. M., & Johnston, M. O. (2019). Patterns and biases in an Arctic herbarium specimen collection: Implications for phenological research. Applications in Plant Sciences, 7(3), e01229. doi:10.1002/aps3.1229 https://doi.org/10.1002/aps3.1229

Premise of the Study: Herbarium specimens are increasingly used in phenological studies. However, natural history collections can have biases that influence the analysis of phenological events. Arctic environments, where remoteness and cold climate govern collection logistics, may give rise to uniqu…

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…

Garroutte, M., Huettmann, F., Webb, C. O., & Ickert-Bond, S. M. (2018). Biogeographic and anthropogenic correlates of Aleutian Islands plant diversity: A machine-learning approach. Journal of Systematics and Evolution, 56(5), 476–497. doi:10.1111/jse.12456 https://doi.org/10.1111/jse.12456

This is the first comprehensive analysis of vascular plant diversity patterns in the Aleutian Islands to identify and quantify the impact of Aleutian Island distance dispersal barriers, geographical, ecological and anthropogenic factors. Data from public Open Access databases, printed floristic acco…

Xie, S.-P., Zhang, S.-H., Chen, T.-Y., Zhang, X.-C., Zeng, X., & Yu, Y. (2018). Late Miocene occurrence of monogeneric family Oleandraceae from southwest China and its implications on evolution of eupolypods I. Review of Palaeobotany and Palynology, 256, 13–19. doi:10.1016/j.revpalbo.2018.05.002 https://doi.org/10.1016/j.revpalbo.2018.05.002

Yunnan in SW China is a world renowned hotspot for diverse species of vascular plants such as ferns. However, fossil records of the Cenozoic ferns there are insufficient to clarify their phylogeny and historical biogeography from a geological perspective. Among these derived ferns, the monogeneric f…

Sheffield, C., & Heron, J. (2018). A new western Canadian record of Epeoloides pilosulus (Cresson), with discussion of ecological associations, distribution and conservation status in Canada. Biodiversity Data Journal, 6, e22837. doi:10.3897/bdj.6.e22837 https://doi.org/10.3897/bdj.6.e22837

Background: Epeoloides pilosulus, one of the rarest bees in North America, is a cleptoparasite of Macropis bees which themselves are uncommon oligoleges of oil-producing Lysimachia flowers. Only two specimens of the cleptoparasite have been reported from Canada since the 1960s, both from Nova Scotia…
