Agroecological farming promotes yield and biodiversity but may require subsidy to be profitable

open access: yesJournal of Applied Ecology, EarlyView.
These results highlight that while evidence for the role of ecosystem services in supporting crop yield can be found, overcoming economic constraints within conventional farming systems is likely to be a key barrier to widespread uptake. Agri‐environmental subsidy payments can offset these costs, but only for moderate interventions.

Control of the woolly apple aphid (Erisoma lanigerum Hausm.) by releasing earwigs (Forficula auricularia L.) and support oil applications - an interim report of first year results [PDF]

open access: yes, 2008
The woolly apple aphid (Erisoma lanigerum Hausm.) has been recognised for some years as a serious pest in organic fruit growing where they may cause severe economic damage due to a lack of control strategies.

Atomic-phase interference devices based on ring-shaped Bose-Einstein condensates: Two ring case

open access: yes, 2002
We theoretically investigate the ground-state properties and quantum dynamics of a pair of adjacent ring-shaped Bose-Einstein condensates that are coupled via tunneling.

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species

open access: yesPlant Species Biology, EarlyView.
We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

An integrative strategy used by the aphid Uroleucon formosanum to counter host sesquiterpene lactone defense: Insights from combined genomic and transcriptomic analysis

open access: yesInsect Science, EarlyView.
We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)

The influence of age on reproductive performance of the predatory ladybird beetle, Propylea dissecta

open access: yesJournal of Insect Science, 2004
The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1-30 days) after a single mating stimulus.
