Characterization of the polyphenolic composition of purple loosestrife (Lythrum salicaria).
Phenolic compounds of purple loosestrife (Lythrum salicaria L.) were analysed by the use of liquid chromatography-mass spectrometry (LC/MS) equipped with atmospheric pressure chemical ionisation (APCI) and electrospray ionisation (ESI). The presence of vitexin and orientin as well as their isomers, isovitexin and isoorientin, were confirmed using ion trap multiple stage LC/MS3 analysis. Several...
متن کاملEvidence of hybridization between Lythrum salicaria (purple loosestrife) and L. alatum (winged loosestrife) in North America.
BACKGROUND AND AIMS Although Lythrum salicaria (purple loosestrife) was introduced to North America from Europe in the early 1800s, it did not become invasive until the 1930s. Whether hybridization with L. alatum (winged loosestrife) could have played a role in its ultimate spread was tested. METHODS Six diagnostic morphological traits (flower number per axil, leaf placement, calyx pubescence...
متن کاملThe Impact of Exotic Purple Loosestrife (Lythrum salicaria) on Wetland Bird Abundances
—The exotic invasive wetland plant purple loosestrife (Lythrum salicaria) is often considered to have negative impacts on native plant and animal species, but this is debated. Clarifying its influence would provide insight into appropriate management actions following invasion. We investigated the influence of L. salicaria cover and density on abundances of wetland bird species that are associa...
متن کاملVegetation-index Models Predict Areas Vulnerable to Purple Loosestrife (lythrum Salicaria) Invasion in Kansas
Purple loosestrife (Lythrum salicaria) constitutes an invasive species detrimental to wetland habitats in North America. To estimate areas vulnerable to it in Kansas, we modeled the potential geographic distribution of the species by using current records in the state, remotely sensed vegetationindex data from the Moderate Resolution Imaging Spectrometer (MODIS), and the Genetic Algorithm for R...
متن کاملRe-establishment of clinal variation in flowering time among introduced populations of purple loosestrife (Lythrum salicaria, Lythraceae).
Range expansion during biological invasion requires that invaders adapt to geographical variation in climate, which should yield latitudinal clines in reproductive phenology. We investigated geographic variation in life history among 25 introduced populations of Lythrum salicaria, a widespread European invader of North American wetlands. We detected a strong latitudinal cline in initiation of f...
