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.

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.</p> <span> <h3>Graphical abstract</h3> <p>The routinary check for health status and performance can provoke distress in cattle.

This anti-predator defense mechanism has been observed across a wide range of animal taxa and is considered adaptive. However, long durations of death feigning can decrease opportunities for feeding and reproduction, and therefore is a fitness cost as compared to environments without predators. Because death feigning is thought to be affected by the balance between survival and other fitness costs, selection pressure may drive individuals who are capable of plastic changes in the intensity of death feigning. Pheromones, which are important semiochemicals that affect foraging and reproductive success, may be one of the factors influencing the intensity of death-feigning behavior. In this study, we investigated the effect of an aggregation pheromone on the death-feigning behavior of the red flour beetle Tribolium castaneum . We found that beetles exposed to the pheromone showed a significantly shorter duration of death feigning than beetles that were not exposed to the pheromone. Therefore, our results suggest that an aggregation pheromone can plasticly alter the death-feigning behavior in T. castaneum .","PeriodicalId":54837,"journal":{"name":"Journal of Ethology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135734890","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}
