Summary: In many animal species, males exhibit different alternative reproductive tactics (ARTs) in obtaining fertilisations, but there is little evidence that ARTs differ substantially in investment into sperm and ejaculates across species. The incongruence between theoretical predictions and empirical results could be explained by the failure of theoretical models to account for differences in overall resource levels between males exhibiting different ARTs, as well as the inaccurate measurement of sperm or ejaculate traits in reflecting overall post-mating investment or affecting fertilisation success.

Summary: This study compared the sperm performance between breeding-coloured males and parasitic sneaker-morph males in sand gobies. The results showed a clear difference in testes gene expression, but only modest differences in sperm performance between the two male morphs. These findings suggest that increased sperm performance as an adaptation to sperm competition is not a primary target of evolution in this species.

Summary: Several predictions of sperm competition theory lack empirical support, potentially due to neglecting how the social environment influences mating dynamics. Understanding these dynamics is crucial for sexual selection and theory predictability. We examined Symphodus ocellatus and found that male social role, interactions, and social environment influenced mating timing. Cooperation with nesting males gave satellites shorter sneak-spawning delays than sneakers, and increased nest activity reduced delays for sneakers but not satellites. Current sperm competition models overlook these dynamics, leading to unsupported predictions. Our study provides insights into the mechanisms underlying variation in spawning timing and potential mismatches between theory and empirical results.

Summary: This study investigated kin structure and its impact on alternative reproductive tactics in mites. Contrary to expectations, fighters were more common in full-sibling groups with higher body weights. This could be due to fighters being more common at low densities in this species, or it may indicate more intense competition among males with relatives.

Summary: The study found that exotic prey fishes with high thiaminase levels can cause thiamine deficiency and reduced fitness in salmonids. Differences in sensitivity to low thiamine availability among Atlantic salmon populations may affect their performance, but the response to low-thiamine diet did not differ significantly among the tested populations.

Summary: By investigating the impact of different biological factors on sperm quality and reproductive success, it was found that sperm quality of early parr from captivity was poorer when subjected to cryopreservation, resulting in reduced reproductive success. Therefore, it is recommended that only the semen of anadromous males should be cryopreserved.

Summary: When there are many competitors but few females available, male spiders change their mating tactics by producing more but lower quality food gifts. This allows them to secure matings while saving energy. The adult sex ratio can affect the intensity of sexual selection, and under intense competition, males may increase their investment in behaviors to outcompete rivals. However, in environments where males are more common, mating opportunities are rare, so males may reduce costly courtship and adopt alternative reproductive tactics.

Summary: Animal societies often evolve due to limited natal dispersal and kin clustering, but some species form cooperative groups with low kin structure. This study investigates the causes and consequences of dispersal decisions in male cooperatively breeding superb starlings, showing that an individual's tactic is related to the prenatal environment its parents experience. Mixed-kin societies are stabilized by climate-driven oscillating selection despite potential social conflict.

Summary: Sexually antagonistic selection has a significant role in the evolution of sex chromosomes. In the shell-brooding cichlid fish, a sexually antagonistic trait, body size, is linked to a 2.4-Mb sex-linked region with candidate genes for body size and sex determination. This study provides evidence supporting the hypothesis that sexually antagonistic traits are linked to young sex chromosomes.

Summary: This review discusses the chemical quality markers of Atlantic salmon, including lipids and pigmentation. These markers are influenced by diet and other important factors. Various analysis methods are used to monitor these quality parameters, with some considered industry standard. However, recent advances in spectroscopic techniques offer faster and non-invasive alternatives with great potential in fisheries science.

Summary: Based on the data collected on mating behavior and spatial behavior of 31 male Alpine chamois individuals during five rutting seasons, this study found that these individuals did not change their mating tactics during the study period, and there were different spatial behavior patterns among territorial males. Territorial males had more mating opportunities than nonterritorial ones, while there were no differences in age, body mass, and frequency of intrasexual aggressive interactions between males adopting different mating tactics.

Summary: In socially monogamous species, females can potentially blackmail their social mates by using their within-pair offspring as 'hostages' to ensure continued care despite paternity loss. However, existing theoretical models fail to explain cases where cuckolded males continue to provide extensive care, due to assumptions about male detection accuracy and parental effort reduction. Further empirical tests are needed to validate theoretical predictions in species with alternative reproductive tactics.

Summary: Intense male competition for access to females often leads to the evolution of alternative reproductive tactics (ARTs). Parental effects play a critical role in ART expression when the parental environment predicts the offspring environment. In this study, researchers investigated maternal effects on male ARTs in two-spotted spider mites and found that mothers produce proportionally more sons under female-biased operational sex ratio (OSR), resulting in increased guarding behavior by sneaker sons. These findings suggest that spider mite mothers adjust their sons' mating behavior based on the predicted level of male competition in the next generation.

Summary: This study investigates the correlation between sex allocation and reproductive behavior in hermaphroditic flatworms. The study finds that hypodermic insemination leads to a more female-biased sex allocation and is associated with selfing or biparental inbreeding. Additionally, a trade-off between male and female reproduction is observed, as well as a correlation between morphological indicators and sex allocation.

Summary: The study found that the abundance of CD99 molecules on the surfaces of LOY cells was lower compared to cells without LOY in six types of leukocytes, while the abundance of CD proteins encoded by genes on autosomal chromosomes was not affected by LOY. These results reveal the impact of LOY on immune-related cellular properties, providing insights into the association between LOY and disease vulnerability in men.

Summary: This study calculated a polygenic risk score (PRS) for LOY using 156 germline variants associated with LOY risk, and evaluated its predictive performance in a large independent population of older men. The results suggest that the PRS for LOY could be a useful tool for risk prediction and targeted intervention for common diseases in men.

Summary: This study finds that hematopoietic mosaic loss of Y chromosome (mLOY) is associated with increased risk of mortality and age-related diseases in men. The animal experiment results show that male mice reconstituted with bone marrow cells lacking the Y chromosome display increased mortality and age-related profibrotic pathologies including reduced cardiac function. Further research reveals that cardiac macrophages lacking the Y chromosome exhibit polarization toward a more fibrotic phenotype, and treatment with a specific antibody can alleviate cardiac dysfunction. A prospective study also reveals that mLOY in blood is associated with an increased risk for cardiovascular disease and heart failure-associated mortality.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
