Negative frequency-dependent selection in female color polymorphism of a damselfly.
TL;DR: This work investigates NFDS in wild populations of the dimorphic damselfly Ischnura senegalensis, in which females occur as andromorphs and gynomorphs, and test fitness responses to morph frequencies, built a simple population genetic model, and compare the observed and predicted morph‐frequency dynamics.
Journal ArticleDOI
Female reproductive success is affected by selective male harassment in the damselfly Ischnura senegalensis
Yuma Takahashi,Mamoru Watanabe +1 more
TL;DR: It is found that males harassed more gynomorphs than andromorphs throughout their daily foraging and oviposition activity period, suggesting that male harassment decreased their reproductive success.
Journal ArticleDOI
Mating Advantage of Multiple Male Ornaments in the Barn Swallow Hirundo Rustica Gutturalis
TL;DR: There was sexual dimorphism in throat coloration and in the size of the white spots in the tail in a population of Barn Swallows Hirundo rustica gutturalis in Japan, indicating a mating advantage for these males.
Journal ArticleDOI
Female mate choice based on territory quality in barn swallows
TL;DR: It is inferred that female swallows choose their mates based, in part, on territory quality, because males with better territories paired with females earlier, and hence bred earlier, than those with inferior territories.
Journal ArticleDOI
Male mate choice based on ontogenetic colour changes of females in the damselfly Ischnura senegalensis
Yuma Takahashi,Mamoru Watanabe +1 more
TL;DR: Female body colour is an important cue for males in discriminating between sexual maturation stages and Learned mate discrimination depending on copulation experience might help males to detect potential mates effectively and avoid sexually unreceptive immature female.
