In fluctuating environments, the fittest genotype can change between generations, and mating with “unsuitable” males will result in reproductive failure due to their genetic or environmental factors. If females cannot discriminate the quality of mates, monandrous mating with “unsuitable” male may lead to reproductive failure. Bet-hedging polyandry hypothesis suggests that polyandry can spread such risks over multiple males and some empirical studies support this hypothesis. However, no studies have considered the effect of female condition on mating acceptance. Because polyandry accumulates the costs of mating, only high conditioned females could accept multiple mating. In this study, females were assigned to monandry (M), two mating polyandry (2P), or three mating polyandry (3P) treatments. All females were mated with three males. For females assigned to the M treatment, for the second and third matings, we removed spermatophores immediately after transfer. For 2P females, the final spermatophore was removed immediately after transfer. Geometric mean fitness across (pseudo) generations as a long-term fitness index (calculated from the egg fertilization rate and egg hatching rate) significantly increased with the number of undisturbed mates. Therefore, the bet-hedging polyandry hypothesis is again supported after adjusting for the female condition.","PeriodicalId":54837,"journal":{"name":"Journal of Ethology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138690388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In extensively bred domestic species, animals are not always used to human handling, and thus also mandatory health checks can alter group dynamics. Here, we investigated possible fluctuations in social behaviors according to the presence and distance from the health check in a group of young Maremmana heifers and steers in semi-extensive conditions. We found that aggression did not change in relation to the health check. On the contrary, the time individuals spent playing and affiliating with each other drastically reduced in the day after the routinary check (Post 1, 0–24 h) if compared to days far from the event (Control): after that, it reached the highest level in the following day (Post 2, 24–48 h). This rebound effect might allow animals to compensate for the previous lack of social interactions and to restore social homeostasis. The findings suggest that social interactions in Maremmana cattle are informative about their internal states. Additionally, social play and allogrooming appear to function as coping strategies for these cattle. <h3>Graphical abstract</h3> The routinary check for health status and performance can provoke distress in cattle. Social play and affiliation drastically reduced the day after the check (Post 1, 0–24 h). In the Post 2 (24–48 h), these social activities had a rebound effect. Aggression did not change in relation to the presence of the health check. On the whole, these findings suggest that social play and allogrooming could be effective coping strategies after handling procedures. <img alt=\"\" src=\"https://static-content.springer.com/image/MediaObjects/10164_2023_801_Figa_HTML.png\"/> ","PeriodicalId":54837,"journal":{"name":"Journal of Ethology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138690452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sexual selection for flight performance may also shape wing design via female preferences for superior performance of flight display. The black-headed bunting Emberiza melanocephala is a polygynous species that is sexually dimorphic in both plumage colour and size. Males perform Towering song-flight, which is a physically demanding display performed only in the presence of receptive females, potentially affecting male mating success. Towering flight features could in turn be influenced by wing morphology. Thus, we studied male wingtip shape in relation to the frequency of Towering song-flights and consequently in relation to the mating success of black-headed bunting males. We found that male mating success was not related to the frequency of song-flights even though it was predicted by male wingtip shape, perhaps suggesting that the quality of Towering flights, in terms of height, steepness or duration of flight, rather than the quantity, influences male mating success.","PeriodicalId":54837,"journal":{"name":"Journal of Ethology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138507429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
