“…Only general male interest and gonopodial swings were repeatable. Sigmoid displays, sneaking attempts and gonopore nipping were not repeatable at all (Table c) because males responded to the change in their social environment (see Řežucha & Reichard ).…”

“…Light was provided by a 25‐W Sun Glo daylight spectrum bulb positioned above the aquarium. Females used in the experiment were collected from a virgin female aquarium and left with a group of 3 adult non‐experimental males from the stock aquarium for 1 d prior to the experimental trials to standardize their receptivity (Řežucha & Reichard ). During Courtship 2 trials (after exposure to social environment treatments), focal males were isolated from all conspecifics for 1.5 d prior to testing to standardize their mating effort.…”

“…). Male P. wingei are capable of modifying their reproductive behaviour according to their phenotypic traits, social environment and intensity of sexual selection (Řežucha & Reichard , ). It is not known whether there is any link between personality and AMB and, if so, whether personality traits and the use of AMB can be modulated.…”

Alternative mating behaviour, personality traits and morphological characters are predicted to be correlated. Bolder, larger and more colourful males are expected to preferentially court females, while shy, small and drab-coloured individuals are predicted to sneak copulations. We used males of Endler's guppy, Poecilia wingei, to test this association over a long temporal period (hence including ontogenetic changes) and under two social environments (male-biased and female-biased). We found that personality traits (exploration, boldness, activity) of P. wingei males were highly repeatable across long time spans, but they were not correlated (formed no behavioural syndrome). Male age and social environment had no effect on any personality trait, despite their effects on alternative mating behaviour. Young males with higher activity levels were more likely to attempt sneaking. In older fish, there was an association between orange coloration, courtship and boldness, but this was not observed in young males. Our results suggest that alternative mating behaviour is more flexible than personality traits and is independent of them. Non-colour-based morphological traits (gonopodium length, body length, caudal straps length, dorsal fin length) were not correlated with any particular mating behaviour.Ethology 122 (2016) 456-467

Implications of our findings extend to female-biased SSD, as we show that the physical predominance seen in large males does not reflect general directional selection in favour of large size; yet context-and frequencydependent benefits of large size still persist.…”

“…The most remarkable example is satellite behaviour, in which parasitic males do not perform courtship by themselves but instead intercept females courted by other males (e.g. guppy [10][11][12] and frog [13]). In this example, parasitic males exploit the investment by other males [2].…”

Social context-dependent modification of courtship behaviour in Drosophila prolongata

Induction of alternative mating tactics by surrounding conditions, such as the presence of conspecific males, is observed in many animal species. Satellite behaviour is a remarkable example in which parasitic males exploit the reproductive investment by other males. Despite the abundance of parasitic mating tactics, however, few examples are known in which males alter courtship behaviour as a counter tactic against parasitic rivals. The fruit fly Drosophila prolongata shows prominent sexual dimorphism in the forelegs. When courting females, males of D. prolongata perform 'leg vibration', in which a male vibrates the female's body with his enlarged forelegs. In this study, we found that leg vibration increased female receptivity, but it also raised a risk of interception of the female by rival males. Consequently, in the presence of rivals, males of D. prolongata shifted their courtship behaviour from leg vibration to 'rubbing', which was less vulnerable to interference by rival males. These results demonstrated that the males of D. prolongata adjust their courtship behaviour to circumvent the social context-dependent risk of leg vibration.
