Fitness consequences of redundant cues of competition in male Drosophila melanogaster

摘要: Phenotypic plasticity can allow animals to adapt their behavior, such as mating effort, social and sexual environment. However, this relies on the individual receiving accurate reliable cues of environmental conditions. This be achieved via receipt multimodal cues, which may provide redundancy robustness. Male Drosophila melanogaster detect presence rivals combinations any two or more redundant cue components (sound, smell, touch) respond by extending subsequent duration, is associated with higher reproductive success. Although alternative rival have previously been found elicit equivalent increases in duration offspring production, securing success under sperm competition has not tested. Here, we explicitly test exposing male D. examine both absence competition. The results supported previous findings terms behavioral responses. there was no evidence benefits accrued response rivals. lack identifiable fitness longer these conditions, competition, contrasted some results, but could explained (a) damage sustained from aggressive interactions leading reduced ability increase ejaculate investment, (b) features environment, female status, that obscured mating, (c) decoupling investment benefits.
