However, we just beginning to understand adaptive significance of observed variation.

Animals are thought to gain significant fitness benefits from choosing high-quality or compatible mates. However, there is large within-species variation in how choosy individuals during mating. This may be because the costs and of being vary according an individual's state. To test this, I systematically searched for published data relating strength animal mate choice both sexes individual age, attractiveness, body size, physical condition, mating status, parasite load. performed a meta-analysis 108 studies 78 species quantify varies In line with predictions sexual selection theory, find that females significantly choosier when they have low load, thus supporting premise expression female dependent on choosy. was not influenced by status. Attractive males were than unattractive males, but male this dataset limited small sample overall correlation between state similar sexes. Nevertheless, explained only amount choice.

Organism condition plays an important role in sexual selection. Sexual ornaments and displays can be condition-dependent, reflecting either underlying genetic quality, experience of environmental stressors, or both. As such, the phenotypic expression such traits, resulting patterns mate choice acting on them, may shaped by intrinsic quality environment.

Many animals devote substantial time, energy and resources to assessing nonmating social partners. However, relatively little is known about how individual characteristics influence the process outcome of partner choice.

Here, we asked personality body size assessment, specific partners chosen, behaviour within groups group offspring production. We evaluated nonsocial traits (exploration, affiliation, aggression, investigation) mass 75 individually marked queens, then released them a large naturalistic enclosure where recorded nest founding on nests. At end season, collected nests measure reproductive output. Exploratory had stronger effect than other measures. More exploratory wasps sampled more partners, joined later spent fewer days members Less were likely become dominant aggressive after partnerships established.

Meta‐analytical evidence that males prefer virgin females DOI Creative Commons

Published: Nov. 21, 2023

Abstract Males are often predicted to prefer virgin over non‐virgin females because of the reduced risk sperm competition. Does this prediction hold across studies? Our systematic meta‐analysis 138 studies, mainly conducted in invertebrates, confirms that males generally females. However, preferred even species with last male precedence, suggesting competition alone does not drive preferences. Furthermore, our results suggest may reject mated when no alternative exists. Preference for virgins is unlikely influence female reproductive success since virginity cannot be selected for, but strong preference could swamp or reinforce selection on other traits. add growing evidence indiscriminate mating. given unexplained heterogeneity effect sizes, we urge caution assuming will and recommend considering natural context mating decisions.

In internally fertilizing species, an individual's mating history (whether they have previously participated in a successful interaction) can influence range of behaviours. For example, often leads to reduction how responsive individuals are future opportunities, especially for females. This fits the prediction sexual selection theory that unmated should be highly stimuli ensure mating. has led many researchers prefer use only females experiments, maximize likelihood will respond stimuli. However, other studies show contrasting results, and this effect not yet been quantified formally. There is also some evidence males species become less after means it unclear general behavioural change is, whether occurs both sexes, or differs across taxonomic groups. I present formal meta-analysis 41 38 animal (mostly arthropod) which confirmed female responsiveness opportunities significantly reduced found no consistent such males. may due greater potential compared females, meaning typically benefit from further matings while do not. collate suggesting most experiments probably exclusively consider male we design experiments.
