Summary: This study provides detailed insights into copulatory behaviors and genetic analysis of male coalition-like formation in stump-tailed macaques. The findings suggest that male-male alliances can form regardless of the degree of kinship/relatedness and that males employing a coalition strategy have higher reproductive success compared to those using a single-male monopoly strategy.

Summary: This study aimed to analyze factors affecting somatic embryogenesis initiation in sugi and found that the plant genotype was the most influential factor. Factors such as initial explant, seed collection time, and culture conditions also played a role in the efficient induction of embryogenic cell lines (ECLs).

Summary: Pollen dispersal patterns and male reproductive success play crucial roles in seed orchard management. Pedigree reconstruction and paternity analysis are important for selecting potential superior paternal clones. This study examined the pollen dispersal pattern in an open-pollinated seed orchard and evaluated the performance of different paternal clones.

Summary: This study compared mating allocations in Nordic Red Dairy Cattle using genomic information, optimizing economic scores while considering genetic level, semen cost, and recessive genetic defects. High correlations were found between pedigree and genomic relationship measures. Linear programming efficiently maximized economic scores for all herds studied, suitable for mating software used by advisors and farmers.

Summary: The study found that post-mating behavior in insects, especially in Chrysomelidae beetles, plays a crucial role in reproductive success. The mating duration and fecundity of males and females have significant effects on reproductive performance, with males displaying mate-guarding behavior.

Summary: Many plants express their female and male sex roles at different times, which has important consequences for mating. Dichogamy can lead to mate limitation due to biased floral sex ratios, especially at the beginning and end of the flowering season. However, plants can adjust their allocations to female and male sex functions to compensate for lost mating opportunities under temporally variable mating environments caused by dichogamy.

Summary: Metabolomics, a method used to study complex biological processes, helps to deepen our understanding of the composition of insect ejaculates and how they are affected by endogenous and exogenous factors. By utilizing technological advances and large-scale data analysis, metabolomics not only reveals molecular interactions in insect ejaculates, but also provides powerful tools to decipher the identity and molecular interactions between males and females during and after mating.

Summary: Recent research has shown that sublethal doses of pesticides can negatively impact the reproduction and population growth of wild bees. A study on the horned mason bee Osmia cornuta found that sublethal doses of the commonly used fungicide Fenbuconazole affected the male's quality signals and mating success.

Summary: A study on wild Guinea baboons found that strongly bonded males support each other more frequently during conflicts, but this does not promote reproductive success. Males that spend less time socializing with other males are associated with more females and sire more offspring.

Summary: This study investigated adolescent and young adult male chimpanzees at Ngogo in Uganda, finding that socially immature adolescent males father offspring by mating with nulliparous females. Mating success was influenced by affiliative bonds and aggression, with male aggression towards females becoming more important as they aged, especially towards females with whom they shared affiliative bonds. These results parallel patterns of sexual coercion in humans, particularly within close affiliative relationships.

Summary: Male-biased operational sex ratios increase male-male competition and select for increased pre- and postcopulatory male success. In this study, we found that males evolved under male-biased sex ratios had higher mating success and courtship frequency compared to females evolved under female-biased sex ratios. Female mating status also influenced male mating success.

Summary: This study investigated the effects of boldness, aggressiveness, and exploration on the number of mating partners, mating events, and offspring surviving until adulthood in the Neotropical poison frog. The results showed that these behavioral traits had diverse and even opposite effects on different components of reproductive success in both males and females.

Summary: The study identified a takeout gene, named Bdtakeout2, highly expressed in the male accessory glands of Bactrocera dorsalis, playing a critical role in male mating behavior and fertility. Treatment with exogenous hormones and photoperiod exposure influenced the expression of Bdtakeout2, affecting male mating success and female fertility.

Summary: Experiments with Daphnia magna showed that male reproductive success decreased as the number of females per male decreased, while female mating and reproductive success decreased at highly female-biased sex ratios and equal sex ratios. Females experienced male limitation at sex ratios below one male to about 50 females, suggesting that mating competition and sexual selection may be present not only in males but also periodically in females.
