Life-history evolution in Anodonta piscinalis (Mollusca, Pelecypoda)

Abstract
The correlations between certain life-history parameters (reproductive effort, reproductive life-span, age of first reproduction, general growth index, variation in juvenile survival, availability of resources) were studied in 13 populations of the mussel Anodonta piscinalis in south-western Finland in 1975 and 1976 Reproductive life-span correlated positively (r s=0,823, Pr s=-0.841, Pr s=-0.676, Pr s=-0.633, Pr and K-selection.
