In many species individuals may adopt one of several different reproductive behaviours, especially in the male sex. [ pdf , 262 KB] Sato T., Hirose M., Taborsky M. & Kimura S.

Head of DivisionProf. The competition for suitable shells is fierce and the ability to transport shells depends on the size of the male. PDF File, Cambridge University Press The different tactics can be largely genetically set and maintained through frequency dependent selection, or depend on the phenotypic condition of the male. Some males may invest in primary access to females through the defence of resources, for example, whereas others circumvent this investment by either parasitising the investment of other males or by forced copulations.

Reproductive behavior is governed by sensitive periods of development during which testicular hormones serve as a type of ‘experience’ that masculinizes and defeminizes the brain and peripheral tissues (Phoenix et al., 1959; reviewed in Ward and Ward, 1985). Sensory ecology and cognition in social decisions Ecol. In the latter case, the fitness of the two tactics may differ with less fit individuals adopting the “best of a bad job”.
