Summary: Size-selective mortality can have evolutionary effects on both life-history and individual behavioral and physiological traits. This study used selection lines of zebrafish to investigate the impact of size-selective mortality on shoal cohesion and the turnover of dopamine and serotonin in the brain. The results showed that shoal cohesion remained consistent throughout ontogeny, indicating the presence of collective personality traits. The study also found asymmetrical responses to size-selective mortality in terms of both behavioral and physiological changes.

Summary: The social context, including group size and identity, affects animals' response to evolutionary traps. In this study, larger group size was associated with faster recovery after predator cues, faster feeding on known foods, and greater likelihood of trying novel foods. The results highlight the importance of social factors in shaping individual behavior and the severity of evolutionary traps.

Summary: Social insects have provided important insights into the evolution of collective behavior. However, the mechanisms underlying the transition from solitary life to superorganismal living in insects remain unclear. The authors propose using molecular data to understand the processes involved in this transition and assess if it occurred incrementally or in a step-wise manner.

Summary: Metabolic changes play a crucial role in tumor growth and also occur during the physiological growth of tissues. Tumors and tissue repair share similar molecular, cellular, and tissue mechanisms, which are integrated within a Systems Biology framework. The polygenic component of complex traits is largely unknown, including in the context of cancer.

Summary: Populations can adapt to new selection pressures through changes in genes of large effect or genes of small effect. This study investigates the polygenic adaptation of Atlantic cod to intense fishing pressure, and shows that populations on both sides of the Atlantic exhibit similar changes in allele frequencies across the genome. This research sheds light on the modes of adaptation in wild populations and the potential for evolutionary rescue.

Summary: This study conducted a multigeneration harvest selection experiment using zebrafish as a model species to investigate the effects of size-selective harvesting on shoaling behavior. The results showed that size-selective harvesting influenced the cohesion of shoals, with small-harvested lines forming more cohesive shoals and large-harvested lines forming less cohesive shoals.

Summary: Selective harvesting in fisheries can evolutionarily alter the life history and behavior of exploited fish populations. Our study on zebrafish showed that size-selective harvesting led to slower associative learning but faster decision-making in the large-harvested line. These results suggest that size-selective fishing can affect the cognitive abilities of exploited fish stocks, potentially impacting resource acquisition and survival.

Summary: Social networks can shape the species composition of the gut microbiome by influencing the ecology of gut bacteria. In an experimental evolution study in mice, it was found that there is a transmission rate of 7% (& PLUSMN;3% 2SE) of E. coli cells per day between hosts living in the same household. The results also showed that hosts with similar diets and habits are expected to have similar microbiome species compositions and evolutionary dynamics.

Summary: Gender inequality in access to leadership positions is evident in human societies, despite lacking evidence that women leaders consistently perform worse than men. Females exercise influence in collective decision-making within small-scale human societies, and female leadership is prevalent in certain contexts in non-human mammalian societies. Differences in competition for political leadership in mixed-gender groups between females and males are influenced by sexual selection and socioecological variation, with cultural norms and institutions playing a role particularly in human societies. The interplay of these factors contributes to the emergence of female leaders within and across species, highlighting the need for further study of underappreciated forms of female leadership.

Summary: In the current Anthropocene epoch, human activities are driving new climatic trajectories, leading to hotter conditions and a range of impacts on the biosphere. Organisms may respond to these changes with acclimation, adaptation, relocation, or extinction, as new abiotic gradients are established. Temperature changes may lead to extirpations, extinctions, and range shifts, but can also prompt phenotypic or behavioral plasticity as species adapt to new conditions. Recent genomic research suggests that some species can evolve rapidly in response to environmental change, offering insights into how temperature might accelerate evolution in the Anthropocene.

Summary: In this study, draft metabolic models were constructed for 332 yeast species, and the evolutionary trend of metabolism among these species was investigated. The results showed a high level of conservatism in yeast metabolic evolution. Additionally, it was found that the evolutionary distance and genotype to some extent determine model similarity, but not trait similarity.

Summary: Our study found that juvenile orange-fin anemonefish residing in bleached anemones experienced a decrease in their standard metabolic rate over time, leading to reduced growth compared to fish from healthy anemones. Despite spending more time foraging in the water column, fish from bleached anemones were less active and had a negative correlation between space use and survival after 4 weeks, highlighting the long-lasting impacts of short-term thermal anomalies on marine animals.

Summary: Interest in measuring metabolic rates is rapidly increasing, particularly in aquatic animal metabolism research. Utilizing intermittent-flow respirometry as a research tool allows for repeated estimation of metabolic rates over time and under various conditions. However, there is a lack of published guidelines for reporting methodological details when using this technique, highlighting the need for standardization in reporting methods.

Summary: The study suggests that individuals with higher metabolic rates may be more social, but not necessarily prefer larger groups; however, the impact on group size choice is weak. Furthermore, variations in food availability and predation risk could further alter the effects of metabolism on group size choice.

Summary: There are strong signals that changing environmental conditions have led to increased migration costs for Atlantic salmon, potentially trapping them in maladaptive long-distance sea migration. If high migration costs persist, population size is likely to decline. However, there is evidence of evolutionary rescue responses in some populations.

Summary: Studies have found that organisms' ability to adapt to climate change does not necessarily lead to changes in their temperature preferences. Research shows that fish living in warm environments have similar temperature preferences to those living in cold environments. Thus, preferred temperature may not be a reliable indicator of a species' adaptive potential to a new temperature environment.

Summary: The effects of global warming on marine ecosystems are expected to increase, leading to changes in the spatial distributions of species, particularly in marine ectotherms like fish. Temperature is a key factor influencing these distributional responses. However, there is a lack of comprehensive synthesis on the ecological factors and methodological factors affecting fish distributions in response to climate change. This study analyzes published studies on range shift responses to global warming in various marine taxa, finding that temperature is a significant driver and factors such as latitude and depth influence the responses.

Summary: Smoking is associated with increased risk of respiratory infections due to alteration of smokers' microbiota. However, the study found that the ecological stability properties of smokers' microbiota are not different from those of nonsmokers, suggesting that the increased risk of respiratory infections in smokers may be more related to changes in the immune system rather than ecological changes in the microbial communities.
