Media are grouped by projects created by users. Projects tend to contain media tied together by a theme. A project might represent the dataset for a single peer-reviewed paper, the results of a collections digitization project, or data for a digital lesson plan.
Projects can be used to share media ownership and access between project members, and projects can also be used to publish assortments of media and specimens for access and discovery by the public. If you want to share media ownership and access with multiple users across multiple projects, consider creating a user team. Projects can be managed by teams, and users with access to that team also gain access to any projects managed by that team.

|Display all details of The relative contributions of multiarticular snake muscles to movement in different planes||Tingle, J.L., D.J. Jurestovsky, and H.C. Astley. 2030. The relative contributions of multiarticular snake muscles to movement in different planes. Journal of Morphology. Muscles spanning multiple joints play important functional roles in a wide range of systems across tetrapods; however, their fundamental mechanics are poorly understood, particularly the consequences of anatomical position on mechanical advantage. Snakes provide an excellent study system for advancing this topic. They rely on the axial muscles for many activities, including striking, constriction, defensive displays, and locomotion. Moreover, those muscles span from one or a few vertebrae to over 30, and anatomy varies among muscles and among species. We characterized the anatomy of major epaxial muscles in a size series of corn snakes (Pantherophis guttatus) using diceCT scans, and then took several approaches to calculating contributions of each muscle to force and motion generated during body bending, starting from a highly simplistic model and moving to increasingly complex and realistic models. Only the most realistic model yielded equations that included the consequence of muscle span on torque-displacement trade-offs, as well as resolving ambiguities that arose from simpler models. Next, we used an ANCOVA to test whether muscle cross-sectional areas or lever arms (total magnitude or pitch/yaw/roll components) were significantly related to snake mass, longitudinal body region (anterior, middle, posterior), and/or muscle group (semispinalis-spinalis, multifidus, longissimus dorsi, iliocostalis, levator costae). Finally, we examined whether vertebral length, muscle cross-sectional areas, and lever arms scaled with geometric similarity (isometry) or allometrically. Our results contribute to knowledge of snake muscles specifically and multiarticular muscle systems generally, providing a foundation for future comparisons across species and bioinspired multiarticular systems.||18||6|

|Display all details of Micro-CT scan of a female Polistes exclamans paper wasp head (Hymenoptera: Vespidae: Polistinae)||This micro-CT image sequence captures structural and neuroanatomical features of the Polistes exclamans female head and brain. The data will be useful for comparative studies of Hymenoptera head and brain morphology. Furthermore the neuroanatomy of Polistes exclamans, in particular the antennal lobe, can be integrated with genomic resources now publicly available for this species to inform odorant receptor gene annotation.||1||1|

|Display all details of CT data for The origin of blinking in both mudskippers and tetrapods is linked to life on land||The project contains three CT scans that were described in the paper entitled, "The origin of blinking in both mudskippers and tetrapods is linked to life on land," by Aiello et al, which was published in PNAS 2023. Scans are of the heads of two mudskipper species (Periophthalmus barbarus and Periophthalmodon septemradiatus) and the round goby (Neogobius melanostomus). All specimens were soft-tissue contrast stained with phosphomolybdic acid, as described in the methods section of the paper||Thomas A. Stewart||3||3|
