Male reproductive output, pollen in plants and sperm in animals has been shown to constitute a substantial cost for many organisms. In parthenogenetic hermaphrodites, selection is therefore expected to reduce the allocation of resources to male repro

Ecological differentiation is widely seen as an important factor enabling the stable coexistence of closely related plants of different ploidy levels. We studied ecological and genetic differentiation between co-occurring sexual diploid and apomictic

SUMMARY As a sequel to biotaxonomic studies in Belgium, about 110 random population samples of Rumex acetosella L. s.l. from a large part of France were studied. Representatives of this polyploid complex were of common occurrence everywhere except in

SUMMARY Cytological studies have demonstrated the occurrence of tetraploids (2n = 28) and hexaploids (2n = 42) of the Rumex acetosella complex in Belgium. Diploids have not been encountered. In both the tetraploid and the hexaploid races angiocarpous
