Summary: This study successfully transformed the coral symbiont Breviolum minutum and developed a method for genetic manipulation. The method allows for specific protein expression in dinoflagellate cells and efficient selection of transformed cells, providing new tools to further understand dinoflagellate biology and key aspects of dinoflagellate-coral symbiosis.

Summary: Wolbachia has a protective effect on viral infection in a natural population of Drosophila, with individuals infected with Wolbachia being less likely to be infected by viruses. This antiviral effect is specific to certain viruses and contributes to the ecological success of Wolbachia.

Summary: This study used point-transect distance sampling surveys to estimate the distribution and abundance of the endangered palila species. A density surface model (DSM) was employed to simultaneously model the species' distribution, abundance, and spatial correlation. The results provide valuable information for species conservation, survey protocols improvement, and management.

Summary: This study presents an analytical framework based on recent developments in structural equation modeling to address research questions focusing on intraindividual or intragroup variability. The framework allows for extensions to accommodate complex research scenarios by parameterizing variability as a latent variable, simultaneously considering other observed and/or latent variables. The proposed methods are demonstrated through empirical examples and their syntax is provided for applied researchers.

Summary: The study found that after 100 generations of adaptation to a new laboratory environment, the variance of gene expression in Drosophila simulans males was significantly reduced in 125 and 97 genes, suggesting that the drastic loss in environmental complexity may have triggered selection for reduced variance. This observation could have important implications for studies of adaptation processes in natural and experimental populations.

Summary: Taylor's law states that the variance of population density is a power function of its mean. The exponent determines the convergence or divergence of the density distribution over time. East Asia, the Pacific, and South Asia have an exponent of 2, indicating a stable distribution. Sub-Saharan Africa has an exponent greater than 2 due to ongoing demographic transition and intense urbanization. Other regions have an exponent lower than 2, indicating completed demographic transition and rural exodus.

Summary: A retrospective review of patients undergoing abdominal wall herniorrhaphy at a tertiary care center from 2013 through 2019 revealed socioeconomic variations between different surgical approaches. Job growth, insurance type, and educational attainment were found to influence the choice of operative approach, contributing to existing disparities in hernia surgery. Surgeons should work towards addressing these inequalities and ensuring equal access to surgical care.

Summary: This review examines population genetic studies of scleractinian corals in the past decade, analyzing the techniques and molecular markers used. The study found that population genetics studies on coral reefs were mainly published in journals such as Coral Reefs and Molecular Ecology, with microsatellites being the most commonly used molecular markers. The Caribbean, Australian Barrier Reef, and South Kuroshio in Japan had the most population genetic data available, while information on the Coral Triangle was limited. The review highlights the need for more genetic data in key locations for coral conservation.

Summary: By applying scaling theory and fast-slow dynamical systems theory, the study found that evolution and plasticity can drive phenotypic change at rates comparable to changes in population densities, regardless of the mode of adaptation.

Summary: This study examines the (co)evolution of host-associated microbiomes and finds that microbial and host fitness tend to trade-off rather than generating conflict. The results highlight the importance of quantifying microbial relative fitness for understanding microbiome evolution and improving host fitness.

Summary: This paper proposes a data-driven multivariate statistical learning approach for studying multidimensional population health, considering the influence of various factors such as health behaviors, clinical care, socioeconomic factors, physical environment, and demographics. The results show that this approach outperforms traditional linear regression and random forest in modeling and predicting population health outcomes. The proposed framework can be used as a decision support tool for accurately assessing and predicting multivariate population health.

Summary: Residential income segregation is a spatial manifestation of social inequality that affects resource access, explored through multilevel multigroup modeling to uncover patterns across multiple scales. Findings show significant variations in segregation levels for different income classes at different scales, with higher-income families less segregated in city centers and middle-income families more segregated in service areas.
