Coexistence of three specialist aphids on common milkweed, Asclepias syriaca.
Coexistence of host-specific herbivores on plants is believed to be governed by interspecific interactions, but few empirical studies have systematically unraveled these dynamics. We investigated the role of several factors in promoting coexistence among the aphids Aphis nerii, Aphis asclepiadis, and Myzocallis asclepiadis that all specialize on common milkweed (Asclepias syriaca). Competitive ...
متن کاملIsolation and characterization of microsatellite loci in the common milkweed, Asclepias syriaca (Apocynaceae).
PREMISE OF THE STUDY Microsatellite primers were developed for the common milkweed, Asclepias syriaca L., to assist in genet identification and the analysis of spatial genetic structure. METHODS AND RESULTS Using an enrichment cloning protocol, eight microsatellite loci were isolated and characterized in a Michigan population of A. syriaca. The primers amplified di- and trinucleotide repeats ...
متن کاملGrowth–defense tradeoffs for two major anti-herbivore traits of the common milkweed Asclepias syriaca
Costs of plant defense are a key assumption in evolutionary ecology, yet their detection has remained challenging. Here we introduce a novel method for quantifying plant growth using the common milkweed Asclepias syriaca and repeated non-destructive size measurements to experimentally test for costs of defensive traits. We estimated mechanistic components of plant growth (relative growth rate, ...
متن کاملSpecificity of induced plant responses to specialist herbivores of the common milkweed Asclepias syriaca
Induced plant responses to herbivory appear to be universal, yet the degree to which they are specific to sets of herbivores is poorly understood. The generalist/specialist hypothesis predicts that generalist herbivores are more often negatively affected by host plant defenses, wheras specialists may be either unaffected by or attracted to these same ‘‘plant defenses’’. Therefore, specialists s...
متن کاملVariation in Ozone Sensitivity Within Indian Hemp and Common Milkweed Selections from the Midwest
Sixteen selections of Apocynum cannabinum (Indian Hemp) and nine of Asclepias syriaca (Common Milkweed) from midwestern USA were exposed to 40 or 80 ppb ozone under controlled conditions within greenhouse continuously stirred tank reactor (CSTR) chambers to evaluate their relative ozone sensitivity. The incidence and severity of ozone-induced symptoms on both species were directly related to oz...
