IMHO, this study generates many interesting questions, particularly, questions related to signalling theory and sexual selection. For example, given that ejaculates have distinct and differential (?) odors, are these cues empolyed by females as indicators and/or as post-ejaculation markers? How are the olfactory cues embedded in ejaculates employed for assortative or dis-assortative mating by females? Has ejaculate odor been ritualized for signalling or display? How does ejaculate odor co-vary with other male traits and/or with female traits and/or with environmental traits? These and scores of additional questions (----->hypotheses) would arise from assessing (variations in) ejaculate odor relative to material in Maynard Smith & Harper 2003 OUP and Westneat & Fox 2010 OUP (n.b. Sections IV & V).
Free-living songbirds show increased stress hormone levels when nesting under white street lights. But different light spectra may have different physiological effects as this study finds, suggesting that using street lights with specific colour spectra may mitigate effects of light pollution on wildlife
