The Florida Museum of Natural History (FLMNH) currently houses nearly 580,000 specimen-lots of close to 3 million specimens of recent mollusks. It is one of the largest collections of its type in North America and, except for new donations, its collection data is entirely accessible online. The collection has grown rapidly since its founding in the early 20th century, especially in the past 50 years. While global in scope, the collection is especially strong in material from North and South America, the Caribbean, Madagascar, Pacific Ocean islands, and south Asia. Holdings have been greatly enriched by biodiversity surveys conducted by museum staff and research associates and by acquisition of relinquished institutional and private collections. Field collections often have linked voucher specimens, tissues, sequence data, and digital images. The FLMNH mollusk collection is an important resource for systematics, biogeography, biodiversity studies, and education.

Preserving and vouchering butterflies and moths for large-scale museum-based molecular research
Butterflies and moths (Lepidoptera) comprise significant portions of the world’s natural history collections, but a standardized tissue preservation protocol for molecular research is largely lacking. Lepidoptera have traditionally been spread on mounting boards to display wing patterns and colors, which are often important for species identification. Many molecular phylogenetic studies have used legs from pinned specimens as the primary source for DNA in order to preserve a morphological voucher, but the amount of available tissue is often limited. Preserving an entire specimen in a cryogenic freezer is ideal for DNA preservation, but without an easily accessible voucher it can make specimen identification, verification, and morphological work difficult. Here we present a procedure that creates accessible and easily visualized “wing vouchers” of individual Lepidoptera specimens, and preserves the remainder of the insect in a cryogenic freezer for molecular research. Wings are preserved in protective holders so that both dorsal and ventral patterns and colors can be easily viewed without further damage. Our wing vouchering system has been implemented at the University of Maryland (AToL Lep Collection) and the University of Florida (Florida Museum of Natural History, McGuire Center of Lepidoptera and Biodiversity), which are among two of the largest Lepidoptera molecular collections in the world.

null (Ed.)A voucher is a permanently preserved specimen that is maintained in an accessible collection. In genomics, vouchers serve as the physical evidence for the taxonomic identification of genome assemblies. Unfortunately, the vast majority of vertebrate genomes stored in the GenBank database do not refer to voucher specimens. Here, we urge researchers generating new genome assemblies to deposit voucher specimens in accessible, permanent research collections, and to link these vouchers to publications, public databases, and repositories. We also encourage scientists to deposit voucher specimens in order to recognize the work of local field biologists and promote a diverse and inclusive knowledge base, and we recommend best practices for voucher deposition to prevent taxonomic errors and ensure reproducibility and legality in genetic studies.more » « less

Introduction: Morphological abnormalities and their underlying causes are well documented and understood in humans and some domesticated animals but are less often reported within wild populations. This is likely because many abnormalities lead to the early death of individuals and typically are only encountered within large samples of specimens. Here, we report an adult female great fruit-eating bat Artibeus lituratus (Chiroptera, Phyllostomidae) collected from Paraguay with notable skull and post-cranial abnormalities. Methods: Specimens, including the atypical A. lituratus, were collected from eastern Paraguay and prepared as skin and skull museum voucher specimens and deposited in the Natural Science Research Laboratory of the Museum of Texas Tech University. Sequences of Cytochrome b (Cyt b) were generated and uploaded to BLAST to confirm species identification. We then quantitatively compared the atypical individual with 15 typical females collected from the same locality using 13 wing measurements and 13 skull measurements. Results: The Cyt b sequence of the atypical specimen was a 100 % match to A. lituratus. The atypical specimen was much smaller from the perspective of overall body size and wing morphology. The skull was also qualitatively different, much smaller and less robust than other female A. lituratus from this site. Mastoids and the sagittal crest were greatly reduced, and the frontal shield was absent in the atypical individual. Discussion and conclusions: We encourage reports of morphological abnormalities to be made as determining rates of abnormalities within populations may indicate their overall health. Key words: Morphological deformity; morphometrics; New World bats; skeletal deformity; skull morphology; wing morphology.more » « less

Scientific collections hold value in a wide range of fields, from conservation to species-restoration. However, many are unaware of collections’ direct contributions to scientific discovery. Collections are a key source of data, but may not be emphasized to emerging scientists as such. While institutions make collections more accessible, preserved specimens may be misunderstood as nothing more than static, dead creatures in cabinets. To combat this, I created a StoryMap on the history of specimen collections and how they have changed, with case-studies and interviews from the California Academy of Sciences that illuminate collections’ roles in modern conservation. StoryMaps are interactive multimedia pieces that present information in novel, highly engaging ways. This more-accessible medium allows for an easily digestible story encompassing 100 years of specimen-collection. Participants between the ages of 18-25 will answer questions before and after reading the StoryMap to gauge how perceptions of the value of scientific collections have changed. Ultimately, this project endeavors to leave young adults with a deeper appreciation for specimen collections and thus contribute to them centering specimens in future decision-making. Young adults are a key generation that is shaping the future of science. Thus, comprehending the value of specimen collections is paramount to ensuring collections are adequately supported in the future, and that research in species conservation continues. As technology rapidly advances, the value of specimen collections grows, and supporting their stewardship ensures access to historical data as new research questions emerge.more » « less

Natural history collections are important resources for research and conservation. Unfortunately, sometimes certain taxa can be hard to identify to the species level or can be misidentified, impacting how those specimens and their accompanying data are used for future research and conservation. African tree frogs (Family Arthroleptidae, Genus Leptopelis) are a group of big-eyed tree frogs found across Sub-Saharan Africa. While they have morphological differences that can help tell members of the genus apart, when in the field species can look similar to each other which gives rise to them being misidentified or unidentified in collections. In particular, Leptopelis exhibit extensive intraspecific variation in coloration and pattern that makes identification based solely on morphology challenging. The goal of this project is to use DNA barcoding of the 16s mtDNA gene and morphological characteristics to update the identification of “Leptopelis sp.” specimens that are part of the California Academy of Science’s Herpetology collection to the species level. By comparing the genetic and morphological data collected to identified reference specimens in the Academy’s collection we can confirm species identification and update the Academy’s database. Having the opportunity to identify species in natural history collections using both genetic and morphological analysis helps us better understand what species are found in an area, and can reveal new localities and range expansions of poorly known species. These data serve as an important baseline for monitoring how species are adapting to global change and enable future research on these poorly known, charismatic frogs.more » « less
