Horizon scanning of potential invasive alien plant species and their distribution in Norway under a changing climate (2025)
Journal Article
Ivison, K., Howard, C., Baldini, L., Essl, F., Pyšek, P., Dawson, W., & Speed, J. D. M. (online). Horizon scanning of potential invasive alien plant species and their distribution in Norway under a changing climate. Ecography, https://doi.org/10.1002/ecog.07604

Invasive alien plant species can cause considerable ecological, economic, and social impacts, and the number of impactful species will likely increase with globalisation and anthropogenic climate change. Preventing potentially invasive alien plant sp... Read More about Horizon scanning of potential invasive alien plant species and their distribution in Norway under a changing climate.

Invasive plants grow taller under experimental warming, but mediated effects of biotic interactions are species‐specific (2024)
Journal Article
Ivison, K., Vange, V., Speed, J. M., & Dawson, W. (online). Invasive plants grow taller under experimental warming, but mediated effects of biotic interactions are species‐specific. Oikos, Article e10932. https://doi.org/10.1111/oik.10932

Understanding the responses of non‐native plants to climate change while accounting for biotic interactions is key to predicting and mitigating future invasion risks. Non‐native invasive plants may benefit from or decline in the face of climate chang...

Non‐Native, Non‐Naturalised Plants Suffer Less Herbivory Than Native Plants Across European Botanical Gardens (2024)
Journal Article
Ivison, K., van Kleunen, M., Speed, J., Vange, V., Pujara, S., Boch, S., Enters, D., Groom, Q., Janovský, Z., Jeschke, J., Joshi, J., Kolb, A., Kollmann, J., Koubek, T., Lemke, T., Matthies, D., Raabová, J., Tielbörger, K., & Dawson, W. (online). Non‐Native, Non‐Naturalised Plants Suffer Less Herbivory Than Native Plants Across European Botanical Gardens. Diversity and Distributions, Article e13938. https://doi.org/10.1111/ddi.13938

Aim: The enemy release hypothesis states that the invasion success of non‐native species is partly due to their escape from natural enemies, e.g., herbivores. Large‐scale studies of herbivory using multiple species across multiple sites are needed to...

Testing enemy release of non‐native plants across time and space using herbarium specimens in Norway (2022)
Journal Article
Ivison, K., Speed, J. D., Prestø, T., & Dawson, W. (2023). Testing enemy release of non‐native plants across time and space using herbarium specimens in Norway. Journal of Ecology, 111(2), 300-313. https://doi.org/10.1111/1365-2745.13998

1. The enemy release hypothesis predicts that invasive plant success is in part due to the absence of natural enemies in the invaded range. However, few studies have assessed how enemy release may vary over time or space. 2. Norway has seen a large i...
