Future warming enhances rates of population increase of arthropod crop pests globally

Ecography, EarlyView.
Arthropod herbivores cause severe crop yield losses worldwide. Global warming is expected to shift their ranges, phenologies and performances, highlighting the need for improved forecasts of their potential expansion and impacts on food security. After decades of experimental research on thermal biology of arthropod crop pests, available data and tools

Performance of specialist and generalist herbivores feeding on cabbage cultivars is not explained by glucosinolate profiles [PDF]

, 2008
Plants display a wide range of chemical defences that may differ in effectiveness against generalist and specialist insect herbivores. Host plant-specific secondary chemicals such as glucosinolates (GS) in Brassicaceae typically reduce the performance of

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

Oikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Contrasting responses of an invasive plant to herbivory of native and introduced insects

Ecological Processes
Background Interactions between alien plants and insect herbivores in introduced ranges may determine their invasion success. However, few studies have investigated whether alien plants respond differently to native and introduced herbivores in their ...

Neighbouring tree effects on leaf herbivory: Insect specialisation matters more than host plant leaf traits

, 2023
Insect herbivory plays a critical role in the regulation of plant populations and community structures. Although the strength of insect herbivory varies with neighbouring tree diversity and identity, it is not clear to what extent insect guilds and leaf ...

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 ...

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 ...

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 ...

Insect eggs can enhance wound response in plants: a study system of tomato Solanum lycopersicum L. and Helicoverpa zea Boddie. [PDF]

PLoS ONE, 2012
Insect oviposition on plants frequently precedes herbivory. Accumulating evidence indicates that plants recognize insect oviposition and elicit direct or indirect defenses to reduce the pressure of future herbivory.
