Project Summary

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.

Current Research

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.

PENs

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.
