Summary: The study suggests that androgens regulate investment in current and future reproduction, but the exact mechanisms are still unclear. Red coloration shows a quadratic relationship with life characteristics, while blue iris color has a negative correlation with survival, indicating the biological significance of different colors.

Summary: This study aimed to fill the knowledge gap between external exposure and effect dynamics by determining the impact of BPA on immune response and constructing a PBTK-TD model. The results showed a high induction of immunomarkers by BPA and different temporal dynamics. Therefore, a thorough characterization of biomarker response is important for further Environmental Biomonitoring.

Summary: The study established immune reference ranges for field studies of three-spined stickleback based on laboratory data and one reference station. These reference ranges were compared to data from uncontaminated and contaminated sites to improve site variability evaluation and provide better discrimination of sites, with lysosomal presence and phagocytosis capacity in autumn identified as potentially relevant immunomarkers for contaminated site identification.

Summary: Maternal effect senescence refers to a decline in offspring viability with maternal age, and its mechanisms in animals remain largely unknown. In this study, the researchers tested this phenomenon in stickleback fish and explored its molecular mechanisms. They found that old females transferred fewer mRNA transcripts of DNA repair genes to their eggs compared to young females, suggesting a reduced capacity of eggs to detect and repair DNA damages. However, maternal age did not influence egg mtDNA density. The offspring of old mothers showed higher rates of hatching, morphological deformity, and post-hatching mortality, indicating the negative impact of maternal effect senescence.

Summary: This study investigated sex-biased mRNA and small non-coding RNA (sncRNA) expression patterns in the brain, adipose tissues, and gonads of the three-spined stickleback. Tissue-specific expression comprising both mRNA and sncRNA between sexes was demonstrated, emphasizing the importance of mRNA-miRNA interactions as well as new presumed genes not yet identified to have gender-specific roles.

Summary: This study investigates the levels of genomic parallelism and the factors predicting parallelism in adaptive radiations of three-spined stickleback. The findings suggest that quantitative variation in phenotypes and environments can predict genomic parallelism, and similar environments are a better predictor of genome-wide parallelism than similar phenotypes. Overall, the study highlights the importance of major phenotypic and environmental factors in shaping common patterns of genomic divergence.

Summary: This study used morphological metrics to investigate differences in sensory systems of three-spined stickleback, revealing variations in the relative size of sensory organs and correlations among sensory systems in fish from different environments. Even populations within the same habitat type showed differences in the direction and magnitude of sensory system correlations.

Summary: Environmental metabolomics aims to comprehensively analyze the metabolites in organisms to reveal biochemical pathways influenced by stressors and potential biomarkers. This study introduces a methodology for untargeted metabolomics in the three-spined stickleback, evaluating differences and complementarities among brain, gills, liver, and whole fish matrices.

Summary: Differences between sexes in trait fitness optima can contribute to genetic diversity through balancing selection, but detecting such conflicts is challenging. Recent studies have found that duplications on sexual chromosomes can create misleading signals of intralocus sexual conflicts. In this study, we investigated intralocus sexual conflicts in three-spined sticklebacks and found only two regions that showed potential conflicts and signals of balancing selection. These results suggest that most intralocus sexual conflicts are transient and do not drive long-term balancing selection.

Summary: Due to the structural similarities of bisphenol substitutes, adverse effects on reproduction are observed in various organisms. The mode of action of these substitutes remains unclear, therefore it is necessary to explore their toxicokinetics. An experiment was conducted on sticklebacks to understand the impact of BPA, BPS, and BPF on immune responses and biomarkers of metabolic detoxification and oxidative stress. The study found that BPS affects oxidative stress and phagocytic activity in a similar way to BPA, despite having different toxicokinetics.

Summary: The study found that the rapid increase in three-spined stickleback population in the central Baltic Sea has reshaped food webs, increased algal blooms, and threatened coastal biodiversity. Different plate armor phenotypes of stickleback showed niche differentiation based on environmental factors, predator and prey abundances, nutrients, and benthic production. The distribution of plate phenotypes suggests that a lower predation regime promotes stickleback with less armor, potentially impacting food web dynamics and the persistence of stickleback in the Baltic Sea.

Summary: The study utilized three-spined sticklebacks as indicator organisms and a multi-biomarker approach to assess water quality in the Meuse basin in Europe. Results showed minimal effects of WWTP effluents on physiological parameters, but multivariate analysis successfully distinguished different study sites.

Summary: This study investigated the thermal tolerance and phenotypic plasticity of three-spined sticklebacks from different thermal histories in response to heat waves. The results showed that the sticklebacks exhibited significant phenotypic plasticity in thermal tolerance, with heat waves increasing their upper thermal tolerance. The individual plasticity to respond to heat waves was negatively correlated with initial thermal tolerance. However, there were no differences in thermal tolerance or plastic responses between sticklebacks from nuclear power plant habitats and control areas, despite low levels of genome-wide divergence.
