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.

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 ...

Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

Oikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

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.

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 ...

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 ...

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.

Integral projection models show exotic thistle is more limited than native thistle by ambient competition and herbivory

Ecosphere, 2015
Both competitors and natural enemies can limit plant population growth. However, demographic comparisons of the effects of these interactions on introduced versus co‐occurring, related native species are uncommon.
