Summary: This paper examines the decision of retailers to introduce store brands and the competition between store brands and national brands. The findings suggest that retailers are more likely to launch store brands when the demand for those brands is low. Contrary to previous studies, our research shows that intense competition does not necessarily lead to the introduction of store brands. Both retailers have incentives to introduce store brands despite lower profits. Manufacturers are advised to maintain fair trade terms and may consider increasing the wholesale prices of national brands when a retailer launches a store brand.

Summary: Despite the long history of sexual selection theory, little is known about the drivers and mechanisms of female sexual selection. Through studying redfronted lemurs, researchers found that female lemurs target close female kin for eviction, suggesting a balanced interplay between sexual selection and kin selection in female competition.

Summary: The success of cancer treatment has improved the survival rate, but there are adverse consequences in female reproductive system due to chemotherapy. Ovarian tissue is sensitive to chemotherapeutic drugs-induced toxicity. Commonly used drugs like doxorubicin, cyclophosphamide, cisplatin and paclitaxel can cause ovarian damage and decline fertility potential in females. Understanding the different toxicity mechanisms will be helpful for developing therapeutic interventions for preserving declining female fertility among cancer survivors.

Summary: The presence of social cues of reproductive competition can promote plasticity in reproductive traits and strategies, which can also potentially be transmitted across generations through maternal effects. This study examined the effects of exposure to different densities of intermale competition cues during egg formation on the reproductive strategies of male crickets. The results showed that males whose mothers were exposed to a high density of males invested less in calling for mates but courted more intensively when they had access to a mate. However, sperm production was not affected by the maternal exposure, suggesting a weaker maternal influence on offspring traits under postcopulatory sexual selection.

Summary: This review discusses the bidirectional communication between the female reproductive tract (FRT) and remote/versatile organs in the body. The framework of the FRT-organ axes, including various axes such as the vagina-gut axis and uterus-brain axis, is comprehensively discussed. Each axis is not only involved in gynecological diseases, but also diseases occurring outside the FRT. The investigation of the FRT-organ axes provides a multi-centric approach to understand the homeostatic mechanism of women's bodies and may lead to new therapeutic approaches for women's health.

Summary: Female reproductive fluids (FRFs) play crucial roles in reproductive functions, but their interactions with sperm under different environmental conditions are not well understood. This study investigated the effects of ejaculate age and FRF on sperm traits in a mussel species and found that FRF altered the effects of ejaculate age on sperm motility, with longer-lived sperm exhibiting stronger responses to FRF. There was also significant variation among males in the relationship between sperm motility and ejaculate age, which was only observed in the presence of FRF. These findings highlight the importance of considering female reproductive physiology in understanding sperm phenotypic plasticity.

Summary: Growing evidence suggests that non-gametic components released by males and females can impact sperm competition outcomes. Female reproductive fluid has been shown to influence ejaculates of different males and bias fertilization towards specific partners. This study investigates the role of female reproductive fluid in rebalancing ejaculate competition, favoring territorial males and allowing females to regain control over the fertilization process.

Summary: This study investigated the relative age effect (RAE) in Luxembourg's football industry. The findings showed that RAE was absent in all age groups except for U7, but significant RAEs were observed in top-level and national teams. This contrasts with the results from large football nations and suggests that open selection systems may limit the prevalence of RAE in football. Additionally, the study found that the performance dependence of RAE is not limited to high-level football, but also occurs at an amateur level.

Summary: Through studying seven long-term continuous primate populations, we found that age has a significant impact on female reproductive performance and offspring survival in most species. This includes longer inter-birth intervals, reduced number of completed interbirth intervals, and lower survival rates among offspring born to older mothers. Maternal age also affects the age at which daughters first reproduce, particularly in species with female-biased dispersal.

Summary: The female reproductive tract in vertebrates has evolved considerable diversification, with the development of Mullerian duct playing a key role. While the formation of the Mullerian duct is a conserved process, genetic regulatory divergence has led to diversity in duct structure. Developmental plasticity in Hox gene code and wnt signaling may underlie the morphological variation of the uterus in mammals and evolution of the vagina, contributing to the diversity of female reproductive tracts seen today in vertebrates.

Summary: Individual participation in patrols varies based on several factors, rather than conforming to expectations from collective action theory. Sighting frequency, age, and hunting participation were the best predictors of patrol participation. Current and former alpha males did not participate at a higher rate than males that never achieved alpha status. These findings suggest that individual participation in group territorial behavior is influenced by multiple factors.

Summary: Populations on the edge of a species' distribution may be fragmented and geographically isolated, leading to lack of genetic exchanges and compromising adaptive potential. A study on chimpanzees in western Tanzania revealed two isolated populations, but with evidence of high gene flow within each cluster. The presence of barriers to gene flow, such as rivers and bare habitats, was confirmed by landscape genetic analyses. Advances in sequencing technologies and landscape genetics approaches can inform conservation efforts of endangered species.

Summary: To address the debate about human exceptionalism, this study examined the reproductive inequality of humans and their position among other mammalian species. The findings show that while humans exhibit lower reproductive skew among males and smaller sex differences compared to other mammals, they still fall within the mammalian range. The study also found that polygynous human populations have higher female reproductive skew compared to nonhuman mammals. These patterns of skew can be attributed to factors such as the prevalence of monogamy, limited degree of polygyny in human societies, and the importance of unequally held rival resources for women's fitness.

Summary: Personality traits in many taxa relate to fitness, but few studies have tested trade-off models in long-lived species. Using behavioral and genetic data from male chimpanzees, we found that Dominance and Conscientiousness traits were consistently associated with rank and reproductive success across the life course. These findings suggest that the trade-off model may not hold in long-lived species and highlight the validity of personality ratings in studying animal behavior.
