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 Molecular evidence of anteroposterior patterning in the pentaradial body plan of echinoderms||The origin of the pentaradial body plan of echinoderms from a bilateral ancestor is one of the most enduring zoological puzzles. Since echinoderms are defined by morphological novelty, even the most basic axial comparisons with their bilaterian relatives are problematic. Here, we used conserved antero-posterior (AP) axial molecular markers to determine whether the highly derived adult body plan of echinoderms masks underlying patterning similarities with other deuterostomes. To revisit this classical question, we used RNA tomography and in situ hybridizations in the sea star Patiria miniata to investigate the expression of a suite of conserved transcription factors with well-established roles in the establishment of AP polarity in bilaterians. We find that the relative spatial expression of these markers in P. miniata ambulacral ectoderm shows similarity with other deuterostomes, with the midline of each ray representing the most anterior territory and the most lateral parts exhibiting a more posterior identity. Interestingly, there is no ectodermal territory in the sea star that expresses the characteristic bilaterian trunk genetic patterning program. This suggests that from the perspective of ectoderm patterning, echinoderms are mostly head-like animals, and prompts a reinterpretation of the events that led to the evolution of the highly derived body plan of echinoderms. Data deposited here comprises the mesh files from a CT-scan reconstruction of the main anatomical features (digestive tract, endoskeleton, water vascular system, main muscles, radial nerve cords) of a Patiria miniata young juveniles, about the same size than the individuals used for the RNA tomography.||Formery, Laurent||6||1|
|Display all details of Gynandromorphism in Heriades and Dianthidium||We report two new records of gynandromorph bees: in Heriades carinata Cresson 1864, the first reported record of a gynandromorph in the genus and the first of the species Dianthidium pudicum pudicum (Cresson, 1879) (Megachilidae) and include descriptions, images, and 3D scans of both specimens. This is the first reported record of a gynandromorph in the genus Heriades and the first of the species D. pudicum pudicum. We also provide images and a 3D scan of the first reported Dianthidium gynandromorph by Hicks (1926), D. curvatum sayi. Cockerell, 1907. We CT scanned each specimen, though these scans did not reveal any internal morphological structures.||Adrian Lee Carper||581||3|

|Display all details of 3D Freshwater Mussels of America||This is a library of photogrammetry scans of all American freshwater mussel species. Scanning for this project is funded by the U.S. Fish and Wildlife Service and is a collaboration between the Florida Museum of Natural History, Smithsonian National Museum of Natural History, Chesapeake Bay Foundation, and U.S. Fish and Wildlife Service. Freshwater mussels are severely imperiled and yet are poorly understood. One critical challenge for freshwater mussels is limited public attention. Hands-on resources represent a critical tool to improve public engagement, but are currently limited. This library of open-source 3-D models of United States mussel species will expand educational opportunities by providing open access to download 3D models for printed replicas to use for education and training. Printed mussels can be used for training and as education and outreach tools for the general public. For Threatened and Endangered species, which are uncommon and difficult to find or require permitting and paperwork to transport, these printed replicas are available to improve access. The realistic and life-like 3D prints from photogrammetry can provide opportunities for hands-on education that might not otherwise be available.||Randall, Zach||13||6|

|Display all details of Stauromatodon SMNS91427||The Middle Triassic was an important time in the evolutionary history of reptiles because it was during this time that many modern groups originated and initially diversified. In this context, the richly fossiliferous deposits of the Ladinian-age Erfurt Formation in southern Germany play an important role in elucidating reptilian diversity during this interval. Here we present an interesting record of a reptile with an unusual dentition. The material comprises a fragment of a left dentary. The teeth are tightly spaced and have chisel-shaped crowns, with the posterolingually extending apices abutting those of the successive teeth and forming a continuous cutting edge. Micro-computed tomography scanning of the jaw fragment revealed the teeth have expanded roots and sit on an open, shallow groove. The Meckelian canal is partially open lingually and a second canal for the inferior alveolar nerve and artery extends parallel to it. Although the preserved anatomical features of the material are insufficient for precise phylogenetic placement, the structure of the robust dentary and its teeth resembles those of some lepidosaurs and certain early Mesozoic marine diapsids. The distinctive morphology of the teeth, combined with the apparent lack of tooth wear, makes it difficult to assess their functional significance. It is interesting that extinct tetrapods with similar tooth morphologies come from strata representing freshwater and brackish water paleoenvironments, which may serve as an additional line of evidence for future functional- morphological assessments.||Sobral, Gabriela||1||1|
|Display all details of Integrative revision of the Lygodactylus gutturalis (Bocage, 1873) complex unveil an undescribed cryptic diversity and their evolutionary history||Lygodactylus is the most speciose gekkonid group in Africa, with several additional, candidate species already identified. However, in mainland Africa several groups remain only partially resolved, and there are several taxonomic inconsistencies. Lygodactylus gutturalis was described from Guinea-Bissau in the 1870s and since then, the species has been recorded from West to East Africa, widely distributed through different biomes and ecoregions. However, this taxon has never been studied in detail. In this work, we use an integrative approach, including molecular phylogenetic analysis, morphometrics, scale accounts, skull osteology and biogeography, to provide the first systematic revision of the L. gutturalis species complex. The L. gutturalis complex is a subgroup within the L. picturatus-group and includes nine well differentiated species. We elevate L. gutturalis dysmicus to full species status, recognize L. depressus as the sister species to L. gutturalis, describe five new species: and propose an additional candidate species that requires further research. Also, in order to shed light on some taxonomic inconsistencies between the L. gutturalis and the L. angularis groups, we take opportunity to revisit the L. angularis-group, within which we elevate L. angularis heeneni and L. angularis paurospilus to full species status. The L. gutturalis-subgroup diversified during the Late Miocene (5–15 mya), probably as a consequence of multiple vicariant events driven by the expansion of the African savannahs and the establishment of climatic refugia.||Javier Lobon-Rovira||110||105|
