The Measurement of Sexual Selection Using Bateman's Principles: An Experimental Test in the Sex-Role-Reversed Pipefish Syngnathus typhle.
Angus J. Bateman's classic study of sexual selection in Drosophila melanogaster has had a major influence on the development of sexual selection theory. In some ways, Bateman's study has served a catalytic role by stimulating debate on sex roles, sexual conflict and other topics in sexual selection. However, there is still considerable disagreement regarding whether or not "Bateman's principles...
متن کاملMate quality influences multiple maternity in the sex-role-reversed pipefish Syngnathus typhle
In the pipefish Syngnathus typhle, pregnant males provide all parental care. Females are able to produce more eggs than males can brood, and consequently females compete more intensely for mates than do males, a phenomenon defined as sex-role reversal. As the genetic mating system influences the operation of sexual selection, we investigate variation in one phenotypic component of mate quality,...
متن کاملSexual selection on female ornaments in the sex-role-reversed Gulf pipefish (Syngnathus scovelli).
Understanding how selection acts on traits individually and in combination is an important step in deciphering the mechanisms driving evolutionary change, but for most species, and especially those in which sexual selection acts more strongly on females than on males, we have no estimates of selection coefficients pertaining to the multivariate sexually selected phenotype. Here, we use a labora...
متن کاملClustered microsatellite mutations in the pipefish Syngnathus typhle.
Clustered mutations are copies of a mutant allele that enter a population's gene pool together due to replication from a premeiotic germline mutation and distribution to multiple successful gametes of an individual. Although the phenomenon has been studied in Drosophila and noted in a few other species, the topic has received scant attention despite claims of being of major importance to popula...
متن کاملSex Recognition via Chemical Cues in the Sex-Role-Reversed Gulf Pipefish (Syngnathus scovelli)
Mate choice is often based on multivariate suites of traits perceived in more than one sensory modality (Partan & Marler 2005). A variety of scenarios have recently been proposed to address how these complex sets of traits evolve (Candolin 2003; Hebets & Papaj 2005) and interact to elicit receiver responses (Rowe 1999; Partan & Marler 2005; Chenoweth & Blows 2006). Sex-role-reversed systems pro...
