Mate choice in the face of costly competition (2003, background): “Assortative mating by traits indicating quality has been documented in several bird species (Filliater and Breitwisch, 1997; Regosin and Pruett-Jones, 2001; Rintamäki et al., 1998; Roulin, 1999; Roulin et al., 2001) and has been predicted by other models ( Johnstone, 1997; Johnstone et al.”
Corticosterone mediates the condition-dependent component of melanin-based coloration (2008, unknown): “The size of black spots covaries positively with humoral immunocompetence (Roulin et al. 2000), parasite resistance (Roulin et al. 2001a), developmental homeostasis (Roulin et al. 2003), calcium bone concentration (Roulin et al. 2006), age at maturity and survival prospects (Roulin & Altwegg 2007).”
Female‐ and male‐specific signals of quality in the barn owl (2001, methodology): “An experiment where clutches were swapped between nests demonstrated that plumage spottiness of genetic, but not foster mother, predicts low parasite fecundity (Roulin et al., 2001).”
Male preference for female foot colour in the socially monogamous blue-footed booby, Sula nebouxii (2005, unknown): “Female ornaments may indicate reproductive or genetic quality, and hence be preferred by choosy males (Jones & Montgomerie 1992; Johnsen et al. 1996; Potti & Merino 1996; Linville et al. 1998; Roulin et al. 2000, 2001; Domb & Pagel 2001; Velando et al. 2001; but see Hill 1993; Tella et al. 1997).”
Testosterone and melanin-based black plumage coloration: a comparative study (2008, background): “…any effect of nutrition or endoparasitism on melanization (Hill and Brawner 1998; McGraw and Hill 2000; McGraw et al. 2002; Poston et al. 2005), whereas resistance to ectoparasites was shown to be related to melanin-based coloration in some species (Roulin et al. 2001; Fitze and Richner 2002).”
Differential effects of a parasite on ornamental structures based on melanins and carotenoids (2002, background): “Thus, in both male and female great tits, the size of the breast stripe is a potential signal to conspecifics for individual parasite load and/or resistance against this ectoparasite, as had been suggested in barn owls for another melanin-based trait (Roulin et al., 2001).”
