Dispersal polymorphisms from natal phenotype-environment interactions have carry-over effects on lifetime reproductive success of a tropical parrot.

摘要: We examined how interactions between an individual's phenotype and its environment affect natal dispersal at multiple scales the effects on lifetime reproductive success using a 22-year study of green-rumped parrotlets (Forpus passerinus). Dispersal increased or decreased depending upon phenotype. Many phenotypic traits environmental conditions that influenced also dispersal, such as clutch size competition, this differed with scale. By examining phenotype-environment interactions, we observed both positive negative rainfall, habitat quality competition The behaviours juveniles typically resulted in higher success. Thus, individuals commonly exhibit ideal free behaviour results provide support for occurrence maintenance polymorphisms. This highlights long-term, carry-over environment, tactic
