  1. 1. The relative effect of gained extra-pair paternity versus ensured within-pair paternity on male fitness in collared flycatchers, Ficedula albicollis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Lan Ma; [2022]
    Keywords : ;

    Abstract : Variation in a male ability to gain extra-pair paternity and maintain within-pair paternity are important sources of variation in male fitness in socially monogamous species and thus become the resource of sexual selection on male secondary sexual traits.
