Executive Summary
The Northern Great Plains Inventory and Monitoring Network includes thirteen park units located in five northern Great Plains states across six ecoregions. Two park units, Jewel Cave National Monument (JECA) and Wind Cave National Park (WICA), protect significant cave resources. These two caves are among the longest caves in the world and have an assortment of underground water resources ranging from drip sites to cave lakes. Subsurface water quantity and quality in the caves is a concern due to groundwater depletion and groundwater contamination from pesticides (aboveground applications), hydrocarbons (vehicle use and related activities), and wastewater effluent (sewage …

Redescription Of Anaschisma (Temnospondyli: Metoposauridae) From The Late Triassic Of Wyoming And The Phylogeny Of The Metoposauridae, Bryan M. Gee, William G. Parker, Adam D. Marsh
United States National Park Service: Publications
Metoposaurids are non-marine temnospondyls that are among the most common constituents of Late Triassic deposits, but despite their abundance, the evolutionary relationships of the group are poorly resolved and have not been fully addressed with modern phylogenetic methods. The genus Anaschisma is one of a number of poorly resolved metoposaurid taxa and was erected to describe two species from the Popo Agie Formation (Carnian) in Wyoming: Anaschisma browni and Anaschisma brachygnatha. Since being named, the genus has been repeatedly synonymized and separated with other taxa in the context of broader revisions of the Metoposauridae. At present, Anaschisma is considered …

Using Redundant Primer Sets To Detect Multiple Native Alaskan Fish Species From Environmental Dna, Damian Menning, Trey Simmons, Sandra Talbot
Using Redundant Primer Sets To Detect Multiple Native Alaskan Fish Species From Environmental Dna, Damian Menning, Trey Simmons, Sandra Talbot
United States National Park Service: Publications
Accurate and timely data regarding freshwater fish communities is important for informed decision-making by local, state, tribal, and federal land and resource managers; however, conducting traditional gear-based fish surveys can be an expensive and time-consuming process, particularly in remote areas, like those that characterize much of Alaska. To help address this challenge, we developed and tested five multi-species environmental DNA (eDNA) primer sets for the simultaneous detection of up to 37 target fish species in a single sample. Using these primer sets can reduce the cost and time needed to perform future studies of fish communities. Our results comparing multiple …

Morphological And Histological Description Of Small Metoposaurids From Petrified Forest National Park, Az, Usa And The Taxonomy Of Apachesaurus, Bryan M. Gee, William G. Parker
Morphological And Histological Description Of Small Metoposaurids From Petrified Forest National Park, Az, Usa And The Taxonomy Of Apachesaurus, Bryan M. Gee, William G. Parker
United States National Park Service: Publications
Metoposaurids are Late Triassic temnospondyls that are abundant components of freshwater deposi- tional settings. Although metoposaurids are represented by hundreds of specimens in collections around the world, the vast majority pertain to large-bodied, relatively mature individuals, and as a result, the early stages of ontogeny are still poorly characterised. Small-bodied metoposaurids from North America have traditionally been assigned to Apachesaurus gregorii, interpreted as a diminutive taxon, but this interpretation has not been rigorously tested. Here we provide a morphological description of two new small-bodied metoposaurid specimens from Petrified Forest National Park, AZ, USA. Both provide various anatomical details that improve …

Testing Methods To Mitigate Caribbean Yellow-Band Disease On Orbicella Faveolata, Carly J. Randall, Elizabeth M. Whitcher, Tessa Code, Clayton Pollock, Ian Lundgren, Zandy Hillis-Starr, Erinn M. Muller
United States National Park Service: Publications
Outbreaks of coral diseases continue to reduce global coral populations. In the Caribbean, yellow band is a severe and wide-spread disease that commonly affects corals of the Orbicella spp. complex, significantly impeding coral reproduction, and hindering the natural recovery of Orbicella spp. populations. Caribbean yellow-band disease (CYBD) lesions may be severe, and often result in the complete loss of coral tissue. The slow spread of CYBD, however, provides an opportunity to test methods to mitigate the disease. Here we report the results of in situ experiments, conducted within Buck Island Reef National Monument in St. Croix, USVI, to test the …
Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms
Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms
United States National Park Service: Publications
Abstract
Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …

Acoustic Surveys Of Bats At Northern Great Plains Parks And Preliminary Results From 2014-16, Daniel S. Licht
United States National Park Service: Publications
Executive Summary
From 2014-16, the Northern Great Plains Inventory & Monitoring Network (Network)—in collaboration with the Midwest Regional Biologist—used acoustic methods to monitor bat populations at 12 Network parks. Six parks were monitored using the nascent North American Bat Monitoring Program (NABat) framework. Six other parks did not meet a priori criteria for inclusion in NABat so they were monitored using similar methods, but a non-systematic sampling frame.
Fifty-five NABat stations were established along with 62 non-NABat stations. Stations were typically monitored for 4-7 nights each year using equipment that records the echolocation calls of bats. Fourteen mobile survey routes …

An Exploratory Examination Of Perceptions Of Impacts To A Coastal Destination: Tourists Versus Locals, Eric Frauman
An Exploratory Examination Of Perceptions Of Impacts To A Coastal Destination: Tourists Versus Locals, Eric Frauman
Journal of Tourism Insights
Do tourists believe they positively or negatively impact the destinations they visit, particularly those that rely on coastal nature and heritage-based environments to attract visitors? How do tourist’s perceptions compare to residents, and what additional insight might this information provide for destination management organizations (e.g., Convention and Visitors Bureau’s) and local government officials? Furthermore, how do residents perceive their own impacts to the communities they live in? As such, this exploratory study, unlike previous studies, compared tourists and residents perceived impacts to a coastal destination. Statistically significant mean differences were found across the social, economic, and environmental condition impact items …

Bat Community Composition And Monitoring For White-Nose Syndrome At First State National Historical Park, Delaware And Pennsylvania, Juliet Nagel, J. Edward Gates
United States National Park Service: Publications
Abstract
In recent years, bats have faced increasingly deadly threats on multiple fronts. Cave-dwelling bats have been decimated by the emergence of a disease, white-nose syndrome (WNS), caused by a fungal pathogen, Pseudogymnoascus destructans; and tree bats are dying in large numbers at wind power facilities. First State National Historical Park (FRST) is a new national park unit located in northern Delaware and Pennsylvania. Prior to this study, little information was available on bat species and their activity and distribution within FRST. To fill this knowledge gap, we conducted an inventory of bat species present at FRST. We used …

Virgil In Virginia: Eighteenth-Century Pastoralism And The Novus Ordo Seclorum, Alley Jordan
Theses
This work examines classical reception in early America. Specifically, it addresses the role of classical ideas on pastoralism in the thought of one of America’s founders, Thomas Jefferson. Jefferson is best known for his role in the forming of United States government, but he was also influential on developing the idea of “America.” As such, his political theory on agrarian republicanism has strong ties to how the classical poets, such as Virgil and Theocritus, likewise thought about the relationship between land and government.
