FEMALE MATE PREFERENCE IS FOR MALE TOTAL LENGTH, NOT TAIL LENGTH IN FERAL GUPPIES
Exaggerated male traits can evolve either directly by female choice of males with those traits or indirectly by female preferences for related traits. In this study, we tested whether female choiceExpand

Larval nutritional environment determines adult size in Japanese horned beetles Allomyrina dichotoma
The effects of larval nutrition and parental size on offspring horn (male) and body size (male and female) were examined in the Japanese horned beetle Allomyrina dichotoma L. (Coleoptera:Expand

Horn Length Is the Determining Factor in the Outcomes of Escalated Fights Among Male Japanese Horned Beetles, Allomyrina dichotoma L. (Coleoptera: Scarabaeidae)
Male horn length in some horned beetles shows a sigmoidal relationship with body size. This has often been considered as the reflection of alternative reproductive tactics of males based on bodyExpand

Reversed sex-change in the protogynous reef fish Labroides dimidiatus
Protogynous hermaphroditism, or female-to-male sex change, is known for many reef fishes including wrasses (family Labridae) in which large males monopolize mating. When the dominant male disappearsExpand

Heritability of male secondary sexual traits in feral guppies in Japan
Abstract Secondary sexual traits of male guppies show remarkable geographic variation, and male guppies can flexibly change the conspicuousness of their sexual traits within a few generations whenExpand

Heritability of the algal-foraging ability: an indirect benefit of female mate preference for males' carotenoid-based coloration in the guppy, Poecilia reticulata
Several sexual selection theories assume certain benefits of female mate preference. The direct benefit, i.e., the direct contribution from males to their offspring and females, has been well testedExpand

Female mate preference based on male orange spot patterns in the feral guppy Poecilia reticulata in Japan
It is known that females prefer males with larger and/or brighter orange spots in many populations of the guppy Poecilia reticulata. However, female preference for male orange spots varies amongExpand
