“…The ¢nding that the colour expression of a male during interaction correlates with his colour expression prior to interaction suggests that contest-independent costs of red coloration or inherent properties of the male limit colour expression. Red coloration is due to carotenoids (Brush & Reisman 1965;Matsuno & Katsuyama 1976;Czeczuga 1980;Wedekind et al 1998), which are essential for the immune system to function properly (e.g. Lozano 1994).…”

In many species, secondary sexual characteristics are used in both male^male competition and in attracting females. This suggests that social control of deception could contribute to the maintenance of honest sexual signalling. In the three-spined stickleback Gasterosteus aculeatus, male red breeding coloration plays a dual role in sexual selection by functioning as both a threat signal in male^male competition and as a cue for female choice. To investigate whether male competition determines the level of signalling, the expression of red coloration and courtship activity were recorded both before and after male interactions. The results show that male competition in£uences signal expression by increasing the di¡erence between males in signalling level. This in turn facilitates female choice and induces a preference for dominant males. Since a preference for dominant males may bene¢t females both directly and indirectly in this species with exclusively paternal care, male^male competition seems to increase the honesty of signalling and, thus, facilitates female choice in relation to male quality. This may increase the intensity of sexual selection and promote the evolution of breeding aggregations.

“…Crozier (1967) demonstrated that increasing proportions of the carotenoid astaxanthin were associated with increasing the intensity of red colouration in Sebastes species. Astaxanthin is the major nuptial pigment in all populations of G. aculeatus examined to date (Brush and Reisman 1965;Matsuno and Katsuyama 1976;Czeczuga 1980), so the suggestion that intermale variability in relative pigment concentrations may be reflected in intermale variability in nuptial colouration is not an unreasonable one. Since the effects of selection on the elaboration of the signal will be constrained by the mechanisms underlying signal production, knowledge of these mechanisms is of paramount importance.…”

“…Changes in both the absolute amount of pigment present and the relative concentrations of different pigments may be responsible for these observed hue shifts. Czeczuga (1980) outlined the pigment profile of a population of freshwater three-spined sticklebacks in Poland. Within this population, developmental changes in the males' integumentary pigments entailed both a minor alteration in the types of carotenoids present and a major shift in the relative propor- tions of the remaining pigments.…”

1989. Experimental investigations of the evolutionary significance of sexually dimorphic nuptial colouration in Gasterosteus aculeatus (L.): temporal changes in the structure of the male mosaic signal. Can. J. Zool. 67: 1767-1777. Although classically described as "red," the three-spined stickleback male's nuptial signal is a complex mosaic of at least three colours: blue eyes, black dorsal -lateral body, and red ventral -lateral body. Seven variables (intensity, hue, and distribution of red body colour; intensity and hue of blue eye colour; intensity and distribution of black body colour) were scored for 19 males across an entire breeding cycle. These variables interacted to produce four distinct male colour mosaic signals corresponding with the stage a male had reached in the breeding cycle. No single variable was sufficient for the delineation of all breeding stages: however, the distribution of red body colour reliably distinguished the courting male from nesting and parental males. Variability in signal intensity between courting males was greatest for the red component of the nuptial signal and both intra-and inter-male variability in the overall intensity of red was greatest during courtship. Based upon these results, future investigations of the role of intersexual selection in shaping the male nuptial signal in this species should offer females a choice between males differing in the intensity of red rather than the traditional "red" versus "nonred" dichotomy.

Experimental investigations of the evolutionary significance of sexually dimorphic nuptial colouration in Gasterosteus aculeatus (L.): temporal changes in the structure of the male mosaic signal. Can. J. Zool. 67 : 1767 -1777. Bien que la forme nuptiale du mile de 1 '~~i n o c h e a trois Cpines soit gknkralement qualifike de rouge D, sa coloration nuptiale est une mosalque complexe d'au moins trois teintes : yeux blues, portion dorsale -latCrale du corps noire et portion ventrale-latkrale du corps rouge. Sept variables (intensitk, teinte et rCpartition de la coloration rouge sur le corps; intensitk et teinte de la coloration bleue des yeux; intensitk et rkpartition de la coloration noire sur le corps) ont Ctk codkes chez 19poissons miles durant tout un cycle de reproduction. L'interaction de ces variables donne lieu quatre mosaiques distinctes chez les miles, correspondant chacune a un stade du cycle de la reproduction. Aucune des variables ne permet a elle seule de delimiter tous les stades de la reproduction; cependant, la rCpartition de la coloration rouge sur le corps permet de distinguer avec exactitude les miles courtisans des miles parentaux ou des miles en nidation. La variation dans l'intensitk du signal entre les miles courtisans se manfeste surtout dans le composante rouge du signal nuptial et la variabilitk de l'intensitk de la coloration rouge entre les miles, et entre deux pkriodes chez un m2me mile, est maximale durant la saison de la cour. Ces r6ultats nous portent a conclure qu'au cours d'C...

“…Perhaps the rate of fading of die red (which is due to carotenoids; Brush and Reisman, 1965;Czeczuga, 1980;Frischknecht, 1993;Matsuno and Katsuyama, 1976) is sufficiently long that die energetics of parental care (Sargent and Gross, 1986) are not strong enough to affect die red over a single breeding cycle. The unchanged maximum of red diroat color may point to die value of diis signal during die parental phase in attracting additional females and/or defending the territory and nest against intruders.…”

Female mate choice and male red coloration in a natural three-spined stickleback (Gasterosteus aculeatus) population

Under laboratory conditions, female three-spined sticklebacks (Gasterosteus aculeatus L.) show a mating preference for intensely red-colored males. We verified this female choice in the field by observing a freshwater stickleback population in its natural habitat. During the egg collection phase, individual courting males were localized with the aid of a dummy of a ripe female, caught and photographed under standardized conditions, and released. After males had stopped collecting eggs, we counted the number of eggs in the nests. The more intense a male's red breeding coloration, the more eggs he received. Simultaneous female choice experiments in the laboratory suggested that ripe females of this population preferred redder males. Breeding activities of the males in the field were clustered and seem to be synchronized within clusters. At one of the breeding sites, more intense red males were in better physical condition, but this was not the case at another site. Although several synchronized breeding cycles were observed, the majority of males seem to complete only one breeding cycle.
