Digitization TCN: oVert: Open Exploration of Vertebrate Diversity in 3D
The oVert (openVertebrate) Thematic Collection Network (TCN) will generate and serve high-resolution digital three-dimensional data for internal anatomy across vertebrate diversity. At a network of digitization centers across the US, we will CT-scan >20,000 fluid-preserved specimens representing >80% of the living genera of vertebrates. This will provide broad coverage for exploration and research on all major groups of vertebrates. We will also generate contrast-enhanced scans to reveal soft tissues and organs for a majority of the living vertebrate families. This collection of digital imagery and three-dimensional volumes will be open for exploration, download, and use to address questions related to the discovery of new species, documenting patterns of anatomical diversity and growth, and testing hypotheses of function and evolution. These new media will provide unprecedented global access to valuable specimens in US museum collections. Our network of leading US vertebrate collections will develop best practices and guidelines for high-throughput CT-scanning, including efficient workflows, preferred resolutions, and archival formats that optimize the variety of downstream applications. We will train museum specialists on the generation, curation, and distribution of 3D data, researchers in using 3D anatomical data, and high school and undergraduate students in the tools for creating 3D anatomical models. To drive the use of these digital specimens by K12 STEM educators, we will conduct teacher-driven workshops that generate freely available lesson plans focused on specific science standards that are based on digital and printed 3D models of specimens in US museum collections.
Data generated by oVert will serve as a catalyst for diverse research projects focused on understanding the vertebrate morphological diversity and dramatically increase the accessibility of specimens housed in US scientific collections. These anatomical phenotypes represent a common currency that facilitates integration across the fields of taxonomy, evolution, developmental biology, comparative physiology, functional anatomy, paleontology, and ecology. We will use x-ray computed tomography (CT) scanning to generate high-resolution digital anatomical data, represented as both 2D image stacks and 3D volumes and surfaces, which can be distributed globally through the on-line data portal MorphoSource. With these 3D digital specimens, US and international research communities will be able to (1) diagnose, describe, and infer patterns of relationships among both living and extinct vertebrates, (2) test hypotheses of morphological evolution such as patterns of disparity, modularity, and phenotype-environment correlations, (3) develop structure-function models for testing hypotheses about morphological adaptations related to, e.g., feeding and locomotion, and (4) explore relationships between brain and nervous system anatomy and both sensory and musculoskeletal function. We will upgrade the interface and functionality of MorphoSource, an on-line data depository for 3D data of biological specimens, improving its capacity to explore media, capture standardized metadata, ingest legacy data from previous and existing projects, supply media information to data aggregators including iDigBio, and engage educators and students. We will support training workshops both on-site at participating institutions and national society meetings of scientists and educators.
Proposed research uses of data generated through oVert project include: 1) diagnose, describe, and infer patterns of relationships among both living and extinct vertebrates 2) test hypotheses of morphological evolution such as patterns of disparity, modularity, and phenotype-environment correlations 3) develop structure-function models for testing hypotheses about morphological adaptations related to, e.g., feeding and locomotion 4) explore intraspecific phenotypic diversity related to spatial variation and ontogenetic transformations 5) explore relationships between brain and nervous system anatomy and both sensory and musculoskeletal function.

Digitization PEN: oMEGA - Online Metrology of Extant Giant Animals for the oVert TCN
This is a Partner to Existing Networks (PEN) award to the Idaho Museum of Natural History to partner with the Open Vertebrate (oVert) Thematic Collections Network (TCN). The oVert TCN is creating high-resolution three-dimensional (3D) data for internal anatomy across the diversity of vertebrate animals. Using computed tomography (CT) scanners at institutional collections across the US, more than 20,000 fluid-preserved specimens will be scanned and made available online for open public use. This PEN complements the oVert TCN program by including vertebrate animals too large to be preserved in fluid or scanned by conventional CT scanners. The oMEGA PEN will use portable surface scanners to provide high-resolution scans of skeletons of large vertebrate animals curated at Harvard, Berkeley, and California Academy of Sciences. The addition of large vertebrates, including whales and elephants, provides an important segment of the animal world to open access collections for researchers and educators. The process of creating this 3D resource will provide training for undergraduate students, and on-site workshops for collections staff. Skeletal models will support TCN activities in creating K-12 STEM lesson plans and 3D-printable resources for the classroom.
The digitized skeletons acquired in this PEN will help fill a major gap in the original TCN and support its research theme on the evolution of vertebrate morphological diversity. By virtue of their large size, vertebrates exceeding 250 kg define upper boundaries of size-dependent anatomical form and function, and therefore push the limits on development and physiology. These skeletal data will provide new opportunities to evaluate gigantism and the tendency of animal lineages toward ever-larger body size. Combined with the other oVert 3D specimens, the TCN's digital collection distributed through MorphoSource and iDigBio will inspire new research questions and provide the raw materials to test hypotheses in a broad range of biosciences.

Functional Quantitative Characters for Ecology and Evolution (FuncQEE)
An award is made to Chicago State University to join the oVert Thematic Collection Network (TCN) as a Partner to an Existing Network (PEN). Computed tomography (CT) scanning will be used to provide 3D data relating to structural diversity for ca. 1,700 specimens of rodents. Rodents are among the most common but also among the most diverse mammals on the planet. They are found in virtually every terrestrial ecosystem, with species ranging from guinea pigs, to prairie dogs, kangaroo rats, flying squirrels, capybaras, lemmings, house mice, and sewer rats. Across this diversity, their bodies vary considerably in size and shape as they adapted to distinct habitats (e.g., Arctic tundra, grasslands, temperate and tropical forests), locomotion (e.g. terrestrial, arboreal, swimming, burrowing habits), feeding preferences (e.g., insectivores, granivores, herbivores, or generalists), and more. Given these vast differences, this project will provide 3D digitized data making it possible to examine and quantify the characters found in this radiation of diversity throughout the rodent tree of life. Undergraduate students at an MSI (Chicago State University) will be trained in CT-scan image processing
The project will generate computed tomography (CT) scans as a basis for 3D modeling of structural diversity for 1,700 specimens of rodents. Sampling will focus on less common species. The 3D data will be available to researchers and educators via MorphoSource. These data will enable studies on functional quantitative characters for ecology and evolution (FuncQEE) as well as studies and lessons ranging from physiology to biomedical applications. The project will bring together scientists and educators from Chicago State University, University of Michigan, University of New Mexico, University of Florida, and Sandia National Laboratory. Master's degree candidates and undergraduate students will receive training, including an effort to provide opportunities for underrepresented, first generation, and/or low-income students in science careers in cutting edge visualization and analytical approaches.

The oUTCT PEN: Outwardly Mobilizing the UTCT Vertebrate Archive for Research and Training
The University of Texas High-Resolution X-ray CT Facility (UTCT) was established in 1997 to make HRXCT - a direct descendant of medical CT - available to researchers in the natural sciences. Through this award, oUTCT will partner with the oVert (openVertebrate) project to make nearly nine terabytes of existing high-resolution X-ray computed tomographic (HRXCT) data publicly accessible, and to train the next generation of students in best practices for these data. Scientists from around the world have brought their most important and precious natural history specimens to UTCT to image and measure their interior features nondestructively. This application of HRXCT technology has been tremendously successful, resulting in the proliferation of scanners at institutions across the country. Over the course of two years, oUTCT will upload HRXCT data for 90 UTCT clients to MorphoSource. About 3000 specimen scans, representing nearly 1,500 fossil and extant vertebrate species, will be made available so they can be easily discovered and downloaded by everyone from scientists to artists to K-12 educators. This mobilization will be accomplished by undergraduate students employed at UTCT, who will learn the basics of HRXCT data acquisition and visualization as well as basic bioinformatics.
The UTCT datasets, acquired in part via dozens of NSF grants and cited more than 18,000 times in academic publications, remain in high demand due to their broad scope, high data quality, and historical significance. This demand has been fueled in part by the public-facing Digital Library of Morphology (DigiMorph.org), an NSF-funded project online since 2002 and housed at UTCT, which serves HRXCT-derived animations for more than 1,000 biological and paleontological specimens. In the oUTCT project, UTCT and DigiMorph will partner with oVert and iDigBio, both at the University of Florida, and the MorphoSource data repository at Duke University to make this unparalleled collection of HRXCT datasets more readily discoverable and more easily repurposed. As part of the educational outreach for this project, oUTCT will also provide training to the oVert community, which spans nearly 20 universities and academic institutions, to maximize the scientific impact of that project. The UTCT will host two short courses per year, cosponsored by oVert and iDigBio, to train students and scientists associated with oVert and MorphoSource in the fundamentals of HRXCT data acquisition, visualization, analysis, and long-term management. These activities will expand the impact of the original oVert project and maximize the return on NSF?s investment in it, UTCT, DigiMorph, iDigBio, and MorphoSource.

CryptoVert - Digitizing small-bodied cryptobenthic fishes for the oVertTCN
The Open Vertebrate thematic collections network (oVert) aims to create a digital resource of computed tomography (CT) scans across the vertebrate Tree of Life. This digital database allows researchers to quickly and efficiently study morphological patterns across all vertebrate groups. One of the most apparent differences among vertebrates is their body size, with some species obtaining large body sizes, while others remain very small even as mature adults. This Partner to Existing Networks (PEN) award will link the Natural History Museum of Los Angeles County with oVert to create a digital repository of data focusing on some of the world?s smallest vertebrates: cryptobenthic fishes. Fishes represent approximately half of the total vertebrate diversity, yet many groups remain understudied. Cryptobenthic fishes, which are small marine fishes that live in a variety of habitats, are one of these understudied groups and their importance in marine ecosystems is only beginning to be understood. This project will complement oVert taxonomically by focusing on an understudied vertebrate group, and methodologically by developing best practices for scanning very small organisms for both bony and soft-tissue anatomy. In addition to their research utility, these scans will be an excellent educational resource that will be incorporated into public museum displays and K-12 classroom lesson plans. Furthermore, processing of CT scans will train undergraduate students in skills that are used in a variety of professional disciplines.
Studying very small organisms comes with inherent challenges, and previous attempts to describe the internal anatomy of small vertebrates was only possible using destructive approaches. This project will focus on 17 different fish families that comprise the majority of cryptobenthic fishes using traditional CT scans to document the skeletal system and contrast-enhanced CT scans to reveal soft-tissue anatomy such as muscle, nervous, and circulatory systems. Cryptobenthic fishes fill a variety of functional ecosystem roles, and the bony and soft-tissue scans associated with this project will create the raw data necessary for researchers to understand how these minute fishes have adapted in different ways to their environment without damaging valuable museum specimens. In combination with CT scans completed by oVert and oVert partners, the products of this project will also be useful for researchers to identify general trends in vertebrate anatomical evolution associated with body size and will be a valuable resource for the development of new questions and hypotheses in a variety of scientific disciplines. Data will be shared with and made available through iDigBio.org and MorphoSource.org.

GalapaGateway: Unlocking Model Evolutionary Systems for Research and Education
The California Academy of Sciences (CAS) is home to the largest and most complete collection of scientific research specimens from the Galápagos Islands, the majority of which can only be accessed by a small number of researchers able to visit the museum. GalapaGateway is a Partnership to Existing Networks (PEN) award that compliments the Open Vertebrate Thematic Collections Network (oVert TCN). This PEN will produce and disseminate high resolution three-dimensional (3D) imagery of approximately 1300 vertebrate specimens of reptiles, birds, and mammals from the Galápagos Islands, thereby increasing accessibility to these historical specimens. Resulting 3D scans will be available free of charge on multiple platforms, including iDigBio, MorphoSource, SketchFab, and a dedicated CAS portal that links scans to specimen data, fieldnotes, and images. Physical 3D models of selected specimens, such as giant tortoises and Darwin?s finches, will be printed for use in education and public outreach at the CAS and at the Charles Darwin Foundation in the Galápagos Islands.
While the oVert TCN aims to scan a single representative of each vertebrate genus, this PEN will image multiple specimens per species to capture within-species variation. Variation within species of Galapagos animals was central to Darwin?s theory of evolution by natural selection and continues to serve as a textbook example for explaining these foundational concepts to students and the general public. Through a combination of computed tomography (CT) and structured light surface scanning, the GalapaGateway project will create morphological data and 3D models of multiple series of closely related taxa from across the Galápagos Archipelago, allowing for in-depth analysis of vertebrate morphology, variation, adaptation, and speciation. 3D surface scanning will be used on specimens too large for traditional CT-scanning machines. Producing these scans of iconic historical specimens from the Galápagos will facilitate a wide variety of academic inquiries, including research into morphology and allometry, development, taxonomy, and adaptive ecology and evolution.

oBird: 3D Photogrammetry of Museum Specimens for Phenomics across the Avian Tree of Life
The oBird project (for ?outside of the bird?) will create 3D digital models for nearly all living bird species for research and education. Preserved specimens in museum research collections are a record of Earth?s biodiversity and provide a baseline for assessing past and future environmental changes, planetary health, and for understanding how biodiversity arose and proliferated. Major efforts over the last several decades have sought to make museum records digital to facilitate their access and inclusion in large-scale research projects. Computerized tomography (CT) scans are an increasingly common way to make digital specimens, especially when the insides of the specimen have also been preserved, as with whole fish preserved in jars. However, with birds, CT scans will miss the color and arrangement of feathers, features of great importance to researchers and also appreciated by the public. oBird will create 3D digital models using a process called photogrammetry. Photogrammetry uses hundreds of photographs from all angles of a specimen to create realistic, interactive 3D virtual models in full, natural color. The 3D models from oBird will be free to access on the internet, facilitating research on the origins of bird diversity, including novel colors and pigments. The 3D models will also be incorporated into public displays on biodiversity in the new Anderson Center for Environmental Sciences at Occidental College as well as lesson plans for K-12 education.
As a partner project to the Open Vertebrate Thematic Collections Network (OVert TCN), oBird will extend OVert into the world of 3D photogrammetry, an emerging method in collections digitization that preserves the external features of specimens as interactive, 3D models. The project will increase genus-level coverage of avian diversity compared to OVert from 60% to 90%. The 3D photogrammetry technique involves taking hundreds of 2D photos of a whole, dried bird specimen on a rotating stand followed by processing with a novel, automated computational pipeline that generates a 3D model with minimal manual oversight. oBird will prioritize imaging the same species as OVert to provide paired external and internal anatomy across species. The 3D models will be hosted on MorphoSource, an open-access platform for storing and archiving 3D data, extending access to large-scale phenomic data in furtherance of the OVert research theme: the evolution of vertebrate morphological diversity. By providing natural-color data for 3D specimens, oBird will thus bring more accurate and realistic color analysis to research on plumage evolution, especially in the comparative context of an existing bird tree of life. New questions that will be enabled include research into the origins and evolution of bird plumage color and morphological novelty in beak dimensions and wing shape, enabling comparative evolutionary study of these important ecomorphological traits. oBird will integrate with a strong undergraduate research program in a large bird natural history collection at a small liberal arts college, providing training in digital technology and effects, biodiversity informatics, and museum collections.

oMeso: Opening Mesoamerican Herpetofaunal Diversity to Whole Phenome Imaging
The oMeso project is a Partner to an Existing Network (PEN) award to the University of Colorado Museum of Natural History to join the openVertebrate (oVert) Thematic Content Network (TCN). oMeso expands upon oVert objectives by using 2D and 3D specimen imaging technologies to facilitate exploration of structural and functional diversity in Mesoamerican reptiles and amphibians. The unique ecology and geology of Mesoamerica has fostered the rapid evolution of multiple species adapted for a variety of habitats and life modes. Computed tomography (CT) scans of internal anatomy paired with high resolution photos of external traits will provide complimentary image datasets to create a novel resource for one of the world?s most hyperdiverse regions. Increased access to digital vouchers generated by oMeso will enable research spanning multiple disciplines, from evolutionary biology and ecology to biomechanics and conservation science. The project provides inclusive training opportunities for university students in curation, data dissemination, and cutting-edge museum technologies. Beyond its research value, the oMeso PEN aims to increase scientific literacy and public engagement around Mesoamerican herpetofaunal diversity through a year-long exhibit accompanied by a community lecture, K-12 programming, and open access lesson plans that incorporate project products.
oMeso will increase the taxonomic scope of the oVert TCN by adding 1100 species across 160 genera, additionally filling a phenotypic data gap in the digital biodiversity landscape pertaining to reptile and amphibian media. These data will broadly support analysis of the patterns and processes relating to evolution, adaptation, convergence, and comparative and functional morphology. Extensive regional sampling will drive investigations into ecomorphology along various environmental gradients, and targeting endemic species will uncover rare or cryptic phenotypes such as those belonging to narrowly distributed microhabitat specialists, endangered, threatened and extinct species, and miniaturized taxa found throughout Mesoamerica. oMeso will leverage existing oVert TCN workflows and digital infrastructure to optimize efficiency and standardize products. Roughly 10% of specimens will be prepared with contrast-enhancement to render soft tissue structures in scans. Resulting raw CT tomograms, 3D surface models, and photo-stacked images will be openly disseminated through MorphoSource and Arctos and integrate with iDigBio, linking project media to corresponding source specimen records and extended data products (e.g., genetic sequences, publications, symbionts). oMeso will bring together collaborators from the University of Colorado, the University of California, Berkeley, and the University of Florida, along with specimen contributions from seven museum institutions to develop this comprehensive and globally accessible whole phenome resource.
