Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

Journal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Nurses' Scope of Practice in Home‐Based Care: An Observational Study of Care Activities, Clinical Decision‐Making, and Contextual Modulators—The DECIDE Project

Journal of Clinical Nursing, EarlyView.
ABSTRACT Background and Aim Nurses' scope of practice is central to healthcare delivery. While scope of practice is well described conceptually, there is limited empirical research capturing how it is enacted in everyday clinical practice. This study aimed to describe scope of practice in home‐based care, focusing on care activities, clinical decision ...

Using a Master Narrative Framework to Examine Conversations About Race and Ethnicity

Journal of Personality, EarlyView.
ABSTRACT Objective Systemic racism, reinforced by color‐evasive ideology, shapes the ways that emerging adults process and discuss race/ethnicity. In this preregistered and mixed methods study, we used a master narrative framework to examine narratives about race/ethnicity among U.S. emerging adult friend‐pairs.
