Nipplewort, Lapsana communis, is an annual weed of the Asteraceae native to Europe and western Asia, first detected in northeastern and Pacific northwestern regions of North America in the 19th century. It appears to have been introduced as a contaminant of imported garden material and seeds, but may also have been deliberately…

Lack of pre-dispersal seed predators in introduced Asteraceae in New Zealand
TLDR
Possible reasons for the low colonization level of the introduced Asteraceae by native insects in New Zealand are the relatively recent introduction of the plants, their phylogenetic distance from the native flora, and the specialised nature of the bud-infesting habit of the insects.
THE BIOLOGY OF LETTUCE ROOT APHID
TLDR
Alternative secondary hosts are not reservoirs for lettuce-infesting alatae, as the sexuparae begin appearing on lettuce from about the last week in August, and all winged alienicolae are sex uparae and fly back to poplar.
A cytological study of the Compositae (excluding Hieracium and Taraxacum) of the British Isles
TLDR
The results of transplant experiments with Solidago virgaurea are discussed and the occurrence of dwarf, genetically main­ tained ecotypes in Aster tripolium L., Leucanthemum vulgare Lam.
A survey of weeds of oilseed rape in central southern England
Summary Weeds in a total of 450 fields of winter oilseed rape in nine areas of central southern England were surveyed, just prior to harvest during summer 1985, to identify those that had survived
Is early flowering in myrmecochorous plants an adaptation for ant dispersal
TLDR
Despite differences in seed size, plants with ant-dispersed seeds show highly synchronous flowering, suggesting that strict myrmecochores in the study area may have adapted their phenologies to the seasonal availability of dispersers.
Seed survival and periodicity of seedling emergence in twelve weedy species of Compositae
TLDR
The numbers of seedlings were greatest in the first year and thereafter decreased approximately exponentially from year to year, except for C. segetum and A. cotula, in which there was evidence of innate dormancy imposed by the seed coat.
Host-associated populations in the lettuce root aphid, Pemphigus bursarius (L.)
TLDR
Evidence was found for a distinct, cyclically parthenogenetic population that exploited Lactuca sativa as its secondary host, and populations associated with Matricaria inodora appeared to be largely composed of obligate parthenogens or may even have been another species of Pemphigus.
Specificity of Bremia lactucae from Lactuca sativa
The Distribution of Dicotyledonous Arable Weeds in Relation to Distance from the Field Edge
TLDR
Numbers of dicotyledonous weed seedlings and seeds in the seed-bank were determined at 10 distances from the crop edge and Viola arvensis was the only species whose numbers increased.
