The evolutionary journey of primates is complex, as lineages disperse between continents and adapt to new ecosystems. The fossil collection at the Duke Lemur Center (DLC) is well positioned to tell this story using primate specimens from the Paleogene of North America and Africa, and the Neogene of Africa, South America, and Madagascar. Founded in 1977, the collection was primarily only accessible – and interpretable – to specialized researchers. Visitors and students unfamiliar with fragmentary fossils and obscure taxonomy faced the daunting task of keeping track of the primate journey while following staff through cabinets and drawers. This contrasted with significant education and outreach efforts at the DLC’s main campus, where noninvasive research on the colony of over 200 living lemurs was accessible to the public through tours, interpretive exhibits, and classroom outreach. Our goal was to work together with the DLC education team to fabricate an exhibit that helped visitors access our Big Idea: Humans and Lemurs Share an Evolutionary History That Spans the Globe. The exhibit space is relatively small and the taxa and time periods are unfamiliar to most visitors. We designed color-coding and symbols that are consistent throughout the exhibit and collection spaces to create a layered experience for visitors. A visit can focus on primate adaptations, ecological niches, plate tectonics, or the geological timescale – all science curriculum goals for different grade levels in North Carolina. The exhibit is also physically layered, with modern primate diversity at eye-level accompanied by infographics that summarize the anatomical distinctions between major clades. Displayed below modern specimens are fossil specimens, demonstrating how fossils are used to understand modern biodiversity and vice versa. This structure is disrupted in the Madagascar section, where subfossil lemur taxa are displayed alongside osteological specimens, emphasizing the recent extinction of Malagasy megafauna. This reinforces the DLC’s larger mission to understand and conserve remaining biodiversity. Exhibit materials were designed with the explicit goal of making them available for collaboration with international partners. The team trained volunteer docents to help visitors access the space, and the exhibit opened to visitors in May 2023. Visitors can provide feedback through a standardized form so we can evaluate exhibit materials and revise them in response to engagement.

Activating the Paleontological Research Potential of Life History Data in Living Collections: A Case Study at the Duke Lemur Center
Interpretations of extinct vertebrate anatomy, behavior, and life history are built upon comparative anatomy data from neontological collections. Ideally, these interpretations are informed by metadata collected while the organism was alive such as diet, mass throughout life, social relationships, and reproductive history. Unfortunately, these data are not available for many specimens as natural history collections have focused on wild-caught individuals for which mass at collection, sex, and collection locality are typically the only associated data. In contrast, extensive life-history data are collected from organisms in sustained human care, but transferring these data from zoos to natural history collections is not standardized or prioritized. The Duke Lemur Center (DLC) has been designing a database that allows researchers access to morphological and life-history data derived from animals that were part of the living research colony. The DLC is home to over 200 lemurs representing 16 different species. The colony has access to open air, multi-acre habitats. For over 50 years the AZA-accredited DLC has been a platform for non-invasive research on strepsirrhine primates and the DLC Museum is the repository for DLC specimens and fossils related to the evolution of primates. The colony’s breeding records, veterinary care, husbandry data, locomotor behaviors, and diets are recorded by researchers and staff. However, these data are disaggregated, making it difficult to explore. The DLC Data Team started by generating microCT scans of the osteology and frozen cadaver collection to make morphological data available on MorphoSource. Preserved specimens were rehoused and inventoried. Now we are using DLC-developed REDCap database management tools to network scans with life-history records, building a database that researchers can use to explore questions such as individual variation in tooth wear, osteological signatures of different pathologies, and individual biomechanical performance. The REDCap database is also used to store fossil metadata like field notes and specimen preparation records. Our goal is to make these database tools available to other living colonies and natural history collections, so life-history data can be shared and standardized across institutions. This effort – in collaboration with the ZooMu network – will ultimately make life histories accessible to researchers – including paleontologists exploring the fossil record.

Abstract Natural history collections are repositories of biodiversity specimens that provide critical infrastructure for studies of mammals. Over the past 3 decades, digitization of collections has opened up the temporal and spatial properties of specimens, stimulating new data sharing, use, and training across the biodiversity sciences. These digital records are the cornerstones of an “extended specimen network,” in which the diverse data derived from specimens become digital, linked, and openly accessible for science and policy. However, still missing from most digital occurrences of mammals are their morphological, reproductive, and life-history traits. Unlocking this information will advance mammalogy, establish richer faunal baselines in an era of rapid environmental change, and contextualize other types of specimen-derived information toward new knowledge and discovery. Here, we present the Ranges Digitization Network (Ranges), a community effort to digitize specimen-level traits from all terrestrial mammals of western North America, append them to digital records, publish them openly in community repositories, and make them interoperable with complimentary data streams. Ranges is a consortium of 23 institutions with an initial focus on non-marine mammal species (both native and introduced) occurring in western Canada, the western United States, and Mexico. The project will establish trait data standards and informatics workflows that can be extended to other regions, taxa, and traits. Reconnecting mammalogists, museum professionals, and researchers for a new era of collections digitization will catalyze advances in mammalogy and create a community-curated trait resource for training and engagement with global conservation initiatives.more » « less

A comprehensive overview of volunteer-driven public programs focused on activities to enhance natural history collections (NHCs) is provided. The initiative revolves around the WeDigBio events and the Collections Club at the Field Museum, aiming to deepen the public’s connection with scientific collections, enhance participatory science, and improve data associated with natural history specimens. The implementation and journey of these programs are outlined, including surveys conducted from 2015 through 2021 to gauge participant motivation, satisfaction, and the impact of these events on public engagement with NHCs. Results show trends in on-site and virtual volunteer participation over the years, especially during the peak period of the COVID-19 pandemic. The majority of participants expressed high satisfaction, indicating a willingness to continue participating in similar activities. The surveys revealed a shift towards more altruistic motivations for participation over time, with increased emphasis on supporting the Field Museum and contributing to the scientific community. The success of participatory science events demonstrates the potential of volunteer-driven programs to contribute meaningfully to the preservation, digitisation, and understanding of biodiversity collections, ultimately transforming spectators into stewards of natural history. From 2015 to present participants celebrate a significant milestone, with over a thousand community scientists contributing to the inventorying, collection care, curation, databasing, or transcription of 286,071 specimens, objects or records. We also discuss accuracy and quality control as well as a checklist and recommendations for similar activities.more » « less

Adam, N.; Neuhold, E.; Furuta, R. (Ed.)Metadata is a key data source for researchers seeking to apply machine learning (ML) to the vast collections of digitized biological specimens that can be found online. Unfortunately, the associated metadata is often sparse and, at times, erroneous. This paper extends previous research conducted with the Illinois Natural History Survey (INHS) collection (7244 specimen images) that uses computational approaches to analyze image quality, and then automatically generates 22 metadata properties representing the image quality and morphological features of the specimens. In the research reported here, we demonstrate the extension of our initial work to University of the Wisconsin Zoological Museum (UWZM) collection (4155 specimen images). Further, we enhance our computational methods in four ways: (1) augmenting the training set, (2) applying contrast enhancement, (3) upscaling small objects, and (4) refining our processing logic. Together these new methods improved our overall error rates from 4.6 to 1.1%. These enhancements also allowed us to compute an additional set of 17 image-based metadata properties. The new metadata properties provide supplemental features and information that may also be used to analyze and classify the fish specimens. Examples of these new features include convex area, eccentricity, perimeter, skew, etc. The newly refined process further outperforms humans in terms of time and labor cost, as well as accuracy, providing a novel solution for leveraging digitized specimens with ML. This research demonstrates the ability of computational methods to enhance the digital library services associated with the tens of thousands of digitized specimens stored in open-access repositories world-wide by generating accurate and valuable metadata for those repositories.more » « less
