Within and Among Patch Variability in Patterns of Insect Herbivory Across a Fragmented Forest Landscape.

PLoS ONE, 2016
Fragmentation changes the spatial patterns of landscapes in ways that can alter the flow of materials and species; however, our understanding of the consequences of this fragmentation and flow alteration for ecosystem processes and ecosystem services ...

Herbivory by a Phloem-feeding insect inhibits floral volatile production. [PDF]

PLoS ONE, 2012
There is extensive knowledge on the effects of insect herbivory on volatile emission from vegetative tissue, but little is known about its impact on floral volatiles.

Theories of care help explain a peri‐urban tree diversity paradox

People and Nature, EarlyView.
Abstract Since diversity is often a management objective for peri‐urban tree communities on public land, one might expect to find greater diversity there than on private land, where such objectives are less common. However, this expectation rests on an assumption that people control diversity towards objectives, overlooking the role of relationships ...

Hyperspectral imaging to characterize plant–plant communication in response to insect herbivory

Plant Methods, 2018
Background In studies of plant stress signaling, a major challenge is the lack of non-invasive methods to detect physiological plant responses and to characterize plant–plant communication over time and space.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Impact of insect herbivory on plant stress volatile emissions from trees: A synthesis of quantitative measurements and recommendations for future research

Atmospheric Environment: X, 2020
Plants, and particularly trees, are the largest source of atmospheric volatile organic compounds globally. Insect herbivory alters plant volatile emission rates and the types of compounds that are emitted.

Transport engineering as a strategy to realize rapeseed's potential as a protein‐rich food

Pest Management Science, EarlyView.
The heavily pesticide‐dependent rapeseed is an under‐utilized protein source for food owing to anti‐nutritional glucosinolates. Transport engineering technology may reduce glucosinolates in seeds while increasing defense in vegetative parts. Abstract Rapeseed is the world's second‐largest oilseed crop, and the low‐value press cake that remains after ...

Genetic Diversity Increases Insect Herbivory on Oak Saplings

PLoS ONE, 2012
A growing body of evidence from community genetics studies suggests that ecosystem functions supported by plant species richness can also be provided by genetic diversity within plant species. This is not yet true for the diversity-resistance relationship as it is still unclear whether damage by insect herbivores responds to genetic diversity in host ...

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

Pest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

Invasive plants reduce functional feeding diversity and trophic interactions of insect herbivores on a remote tropical island.

PLoS ONE
Invasive plants are a driver of global insect decline, yet their impacts on trophic interactions in insular tropical island ecosystems remain poorly understood.
