Weak integration allows novel fin shapes and spurs locomotor diversity in reef fishes.

In complex functional systems composed of many traits, selection for specialized function can induce trait evolution by acting directly on individual components within the system, or indirectly through networks of trait integration. However, strong integration can also hinder diversification into regions of trait space that are not aligned with axes of covariation among traits. As a result, non-independence among traits may limit capacity for functional expansion.

Complexity and weak integration promote the diversity of reef fish oral jaws.

Major trade-offs often manifest as axes of diversity in organismal functional systems. Overarching trade-offs may result in high trait integration and restrict the trajectory of diversification to be along a single axis. Here, we explore the diversification of the feeding mechanism in coral reef fishes to establish the role of trade-offs and complexity in a spectacular ecological radiation.

Replicated Functional Evolution in Cichlid Adaptive Radiations.

AbstractAdaptive radiations highlight the mechanisms by which species and traits diversify and the extent to which these patterns are predictable. We used 1,110 high-speed videos of suction feeding to study functional and morphological diversification in 300 cichlid species from three African Great Lake radiations of varying ages (Victoria, Malawi, and Tanganyika) and an older, spatially dispersed continental radiation in the Neotropics. Among African radiations, standing diversity was reflective of time.

Effects of glucagon-like peptide-1 receptor agonists on upper endoscopy in diabetic and nondiabetic patients.

Background And Aims: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) promote weight loss by suppressing appetite, enhancing satiety, regulating glucose metabolism, and delaying gastric motility. We sought to determine whether GLP-1 RA use could affect medical procedures such as EGD.

Methods: We conducted a retrospective study of 35,183 patients who underwent EGD between 2019 and 2023, 922 of whom were using a GLP-1 RAs.

Promoting Health Equity Through the Power of Place, Perspective, and Partnership.

The 10 articles in the Preventing Chronic Disease (PCD) special collection on health equity highlight that a commitment to self-reflection, cultural humility, and lifelong learning are foundations of health equity science and that the field is interdependent with the perspectives and context of communities.Three themes - place, perspective, and partnership - emerged from the PCD special collection. The articles embody the principles outlined in the Healthy People definition of health equity and CDC's CORE Health Equity Science and Intervention Strategy.
