Variability and repeatability of female mating preference in the guppy

Article Abstract:

Additive genetic variation for mating preferences on the basis of male color pattern is maintained, and there exists the opportunity for the further evolution of both bright male color patterns and female preferences for their trait. The study on the Trinidadian guppies, Poecilla reticulata revealed that the more brightly colored or the two similar sized males are preferred by substantial number of female guppies. There is a remarkable consistency in the selection of mates by individual females, though there is strong variation among the females for the brightly colored males.

Female mate choice under predation risk in the guppy

Article Abstract:

An experiment was conducted to observe the sexual behavior of female guppies under risk of predation. The first-generation, laboratory-reared offspring of wild guppies from the West Indies were used, and females were reared separately from males. Results were consistent with the general hypothesis that female mate choice in the guppy carries an increased risk of mortality due to predation, and female guppies are sensitive to this risk, exhibiting the appropriate behavior depending on the intensity of the predation under which they have grown.

A reply to Lombardi & Hurlbert

Article Abstract:

The errors in the data suggested by C.M. Lombardi and S.H. Hurlbert fail to obscure the most important result that bluegill sunfish are capable of using strategic behavior. The use of fewer degrees of freedom makes two biologically non-significant results statistically non-significant. Pseudoreplication is a pervasive problem and it is difficult to avoid it completely. Some basic statistical issues are discussed with reference to the critique of Lombardi and Hurlbert.
