英文摘要
The immunocompetence handicap hypothesis (ICHH) assumes that males with attractive sexual ornamentation are more handicapped than their less ornamented rivals because of the immunosuppressive androgens required for the production of secondary sexual characters. The predictions of ICHH were tested in freshwater fishes. The present results supported assumptions of ICHH [1) females prefer males with exaggerative sexual traits, 2) expressions of male sexual traits used in female choice are controlled by androgens, 3) androgens have immunosuppressive effects] in the pale chub Zacco platypus (Cyprinidae). This study suggests that ICHH is useful as a model of evolution of sexual dimorphisms in fishes.
