“…Distinguishing between the influence of males' fighting experiences and mating choice of females is a complex task. While some studies suggest that previous fighting experience may impact males' motivation to court females [17,[27][28][29], some others show that these are some males' phenotypic traits perceived by females that explain differences in reproductive success after fights [23,41]. In another context, such as eavesdropping situation, female can assess dominance status of males by having watched their aggressive interactions.…”

In animals, the access to vital resources often relies on individuals’ behavioural personality, strength, motivation, past experiences and dominance status. Dominant individuals would be more territorial, providing them with a better access to food resources and mate. The so-called winner and loser effects induce individuals’ behavioural changes after experiencing a victory or a defeat, and lead to an individual persistent state influencing the outcome of subsequent fights. However, whether and how development of winner and loser effects affect individuals’ fitness is controversial. The aim of this study is to evaluate how individuals’ fitness can be influenced by previous fighting experience in Drosophila melanogaster. In this study, we assess various behavioural performances as indicators for dominant and subordinate fitness. Our results show that subordinates are less territorial than dominants although their locomotor abilities are not affected. We also demonstrate that in a non-competitive context, experiencing a defeat reduces males’ motivation to court females but not the reproductive success while in a competitive context, it negatively affects males’ reproductive success. However, we found no impact upon either males’ ability to distinguish potential mates nor on females’ choice of a specific mating partner. Overall, these results indicate that previous defeats reduce reproductive success, a commonly used estimate of individual fitness.

“…Winner and loser effects are found in a wide range of species including humans [ 13 ], mammals [ 14 ], fish [ 15 ], birds [ 16 ], crustaceans [ 17 ], arthropods [ 18 ] and in fruit flies [ 11 ], and may durably impact animals’ behaviour. Contests may influence behaviour in various ways according to the sex and the species.…”

“…Past investment in mating effort by males can convey beneficial information about attractiveness or competitiveness and the likelihood of sperm competition. For example, the outcome of male–male contests can create “winner-loser” effects, whereby past winners adjust their behavior and have higher subsequent reproductive success ( Trannoy et al 2016 ; Filice and Dukas 2019 ; Kola et al 2021 ; review: Hsu et al 2006 ). In field crickets and wolf spiders, prior exposure to male courtship enhances female choosiness ( Hebets and Vink 2007 ; Atwell and Wagner Jr 2014 ) and alters how much effort males put into mating ( Clark et al 2012 , 2015 ; Gray and Simmons 2013 ).…”

Past reproductive effort allows males to assess their ability to acquire mates, but it also consumes resources that can reduce their future competitive ability. Few studies have examined how a male’s reproductive history affects his subsequent mate choice; and, to date, no study has determined the relative contribution of past mating behavior and past ejaculate production because these two forms of investment are naturally highly correlated. Here, we disentangled the relative effects of past mating behavior and past ejaculate production in mosquitofish (Gambusia holbrooki) by experimentally preventing some males from ejaculating when trying to mate. We assessed the effect of mating behavior on mate choice by comparing males that had previously been with or without access to females and male rivals for 8 and 16 weeks; and assessed the effect of ejaculation on mate choice by comparing males that either could or could not ejaculate when they had access to females for 16 weeks. Reproductive treatment did not affect male attractiveness, but it did affect male mate choice. Somewhat surprisingly, in 5 of the 6 treatment-age at testing combinations, males preferred a female in the vicinity of a male rival over a solitary female. This preference was marginally stronger for males that had previously engaged in mating behavior but was unaffected by past ejaculate production. We discuss the potential benefits to males of associating with another male when seeking mates. This is the first study to quantify the relative influence of pre- and post-copulatory reproductive investment on male mate choice.
