Linking landscape structure, floral resource distribution, pollen use and movement distances of a generalist predator

open access: yesJournal of Applied Ecology, Volume 61, Issue 11, Page 2798-2808, November 2024.
Our findings suggest that the spatial distribution of flowering wild plants can inform movement patterns of lacewings and other flower‐visiting insects in agricultural landscapes. In addition, the location of floral resources in the landscape is important for its capacity to sustain natural enemies. Given the strong reliance of lacewings on pollen from

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

open access: yesJournal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.

Predicted impact, establishment and distribution of Heikertingerella sp. (Coleoptera, Chrysomelidae), recently released for the biological control of Tecoma stans in South Africa Impacto, establecimiento y distribución previstos de Heikertingerella sp. (Coleoptera, Chrysomelidae), liberado recientemente para el control biológico de Tecoma stans en Sudáfrica

open access: yesAgricultural and Forest Entomology, Volume 26, Issue 3, Page 410-420, August 2024.
Abstract Biological control practitioners are required to demonstrate that candidate agents are not only safe for release, but will establish widely in their new range with a significant impact on the target weed. We conducted this study in quarantine to provide insight into the impact and distribution of the root‐feeding flea beetle Heikertingerella ...

Achieving conservation and restoration outcomes through ecologically beneficial aquaculture

open access: yesConservation Biology, Volume 38, Issue 1, February 2024.
Abstract A range of conservation and restoration tools are needed to safeguard the structure and function of aquatic ecosystems. Aquaculture, the culturing of aquatic organisms, often contributes to the numerous stressors that aquatic ecosystems face, yet some aquaculture activities can also deliver ecological benefits.
