Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2414-2428, September 2025.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.

Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities

open access: yesGlobal Change Biology, Volume 31, Issue 3, March 2025.
Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.

Bornean tropical forests recovering from logging at risk of regeneration failure

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
The study investigates the impact of active restoration, such as enrichment planting, on the regeneration of logged forests in North Borneo. It found that while such interventions increase initial seedling production in logged forests, this is followed by higher seedling mortality and species diversity or evenness are not enhanced compared to natural ...
