Parthenogenetic and Bisexual Populations of Ephemerella Notata Eat. in Poland

  • Adam Głazaczow


The sex ratio (males: females) of final instar nymphs of Ephemerella notata varies from 0.12: 1.00 to 0.92: 1.00 in isolated populations of the Pomeranian Lake District in Poland. These data support the view that facultative parthenogenesis occurs in this species. The incidence of parthenogenesis was inversely related to population density. Parthenogenetic populations were less variable in size (determined by a principal component analysis of a total body-size index) and more synchronous in their development.
