Females that experience threat are better teachers.
Superb fairy-wren (Malurus cyaneus) females use an incubation call to teach their embryos a vocal password to solicit parental feeding care after hatching. We previously showed that high call rate by the female was correlated with high call similarity in fairy-wren chicks, but not in cuckoo chicks, and that parent birds more often fed chicks with high call similarity. Hosts should be selected t...
متن کاملReed bunting females increase fitness through extra-pair mating with genetically dissimilar males.
Females of many socially monogamous species accept or even actively seek copulations outside the social pair bond. As females cannot increase the number of offspring with promiscuous behaviour, the question arises why they engage in extra-pair mating. We used microsatellite data to determine paternity, heterozygosity and genetic relatedness in the reed bunting (Emberiza schoeniclus), a species ...

متن کاملEvolution: When Females are Brighter than Males
Females are usually considered to be more choosy than males when seeking a mating partner, resulting in the evolution of attractive males. When males are the limiting resource for receptive females, however, the females may become brightly coloured.
متن کاملEvolution: Good Males Are Bad Females
Manipulation of Drosophila melanogaster genomes allows large numbers of genes to be transmitted solely through males, thereby allowing selection to optimize flies for male function alone. It seems biasing phenotypes toward the male optima has serious fitness costs for females.
