Direct and indirect root defences of milkweed (Asclepias syriaca): trophic cascades, trade‐offs and novel methods for studying subterranean herbivory
Summary 1. Entomopathogenic nematodes can function as indirect defence for plants that are attacked by root herbivores. By releasing volatile organic compounds (VOCs), plants signal the presence of… Expand
Natural selection on and predicted responses of ecophysiological traits of swamp milkweed (Asclepias incarnata)
Summary 1 Given the rapid and reversible impact of the environment on plant ecophysiological traits, it has been speculated that such traits may have low heritabilities, high phenotypic… Expand
Cardenolides, induced responses, and interactions between above- and belowground herbivores of milkweed (Asclepias spp.).
Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above- and belowground plant defenses been considered simultaneously. Milkweeds in the… Expand
Above-ground herbivory by red milkweed beetles facilitates above- and below-ground conspecific insects and reduces fruit production in common milkweed
Summary Initial herbivory and induced plant responses can influence subsequent above- and below-ground herbivore attack. When two life stages of the same herbivore damage different plant parts… Expand
Specific impacts of two root herbivores and soil nutrients on plant performance and insect–insect interactions
Soil-dwelling insects commonly co-occur and feed simultaneously on belowground plant parts, yet patterns of damage and consequences for plant and insect performance remain poorly characterized. We… Expand
