Description
Summary:Lumbriculus variegatus (Müller) is reported from Newfoundland and Labrador in asexual populations with occasional sexual individuals. The life history of a population inhabiting a temporary pool at Logy Bay is described. The season of maximum regeneration is shown to be the first 4 months of the year and the adaptive significance of this is discussed. The possibility that the regeneration season of the species may be only a period of reduced juvenile mortality is discussed.
