About the Laboratory
The National Wildlife Health Center (NWHC) provides the services of board-certified veterinary pathologists specializing in gross and microscopic assessment of animal tissues to help understand the impacts of contaminants on wildlife species. The NWHC also offers real-time reporting of wildlife mortality events and maintains an extensive database of...
Necropsy & Pathology
The Necropsy and Pathology capabilities are performed by diagnostic veterinary pathologists and necropsy technical staff whose principal role is to determine the cause of death for animals submitted to the USGS National Wildlife Health Center (NWHC). These scientists examine carcasses to verify species and condition, collect and process photographic and radiographic images, conduct detailed...
Elemental and radionuclide exposures and uptakes by small rodents, invertebrates, and vegetation at active and post-production uranium mines in the Grand Canyon watershed
The effects of breccia pipe uranium mining in the Grand Canyon watershed (Arizona) on ecological and cultural resources are largely unknown. We characterized the exposure of biota to uranium and co-occurring ore body elements during active ore production and at a site where ore production had recently concluded. Our results indicate that biota...
Cleveland, Danielle; Hinck, Jo Ellen; Lankton, Julia S. Brodifacoum toxicity in American Kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure
A seminal question in ecotoxicology is the extent to which contaminant exposure evokes prolonged effects on physiological function and fitness. A series of studies were undertaken with American kestrels ingesting environmentally realistic concentrations of the second-generation anticoagulant rodenticide (SGAR) brodifacoum (BROD). Kestrels fed BROD...
Rattner, Barnett A.; Volker, Steven F; Lankton, Julia S.; Bean, Thomas G.; Lazarus, Rebecca S.; Horak, Katherine E. Postmortem evaluation of reintroduced migratory whooping cranes (Grus americana) in eastern North America
Endangered whooping cranes (Grus americana) have been reintroduced into the eastern U.S. to speed recovery efforts. This study reviewed necropsy and diagnostic records of 125 crane carcasses recovered during the project’s first 15 years following release of 268 cranes. The proportions of causal classifications did not differ significantly from a...
Yaw, Taylor J.; Miller, Kimberli J.; Lankton, Julia S.; Hartup, Barry K. Wing abnormality in wild-hatched Whooping Crane (Grus americana) chick from the Louisiana nonmigratory population
We describe a wing abnormality present in a wild-hatched Whooping Crane (Grus americana) chick from the reintroduced Louisiana nonmigratory population. Despite its compromised flight ability, the chick fledged, reached independence, and lived until 13 months of age. Necropsy revealed a healed fracture near the left carpus likely resulting from...
Vasseur, Phillip L.; Zimorski, Sara E.; Szyszkoski, Eva K; LaCour, James M; Lankton, Julia S. Virally-vectored vaccine candidates against white-nose syndrome induce anti-fungal immune response in little brown bats (Myotis lucifugus)
White-nose syndrome (WNS) caused by the fungus, Pseudogymnoascus destructans (Pd) has killed millions of North American hibernating bats. Currently, methods to prevent the disease are limited. We conducted two trials to assess potential WNS vaccine candidates in wild-caught Myotis lucifugus. In a pilot study, we immunized bats with...

Scott; Lopera-Madrid, Jaime; Klein, Bruce; Osorio, Jorge E.; White, J. Paul Mortality due to Tyzzer's disease of muskrats in northern Ohio, USA
In 2017, we investigated a mortality event of muskrat (Ondatra zibethicus) in Northwest Ohio, USA, and determined the causes of death to be from Tyzzer's disease due to Clostridium piliforme and Klebsiella pneumoniae septicemia. The gross presentation resembled tularemia, which highlighted the importance of a complete...
Grear, Daniel A.; Lankton, Julia S.; Zaleski, Sara; Witt, Mark; Lorch, Jeffrey M. Assessment of chronic low‐dose elemental and radiological exposures of biota at the Kanab North uranium mine site in the Grand Canyon watershed
High‐grade U ore deposits are in various stages of exploitation across the Grand Canyon watershed, yet the effects of U mining on ecological and cultural resources are largely unknown. We characterized the concentrations of Al, As, Bi, Cd, Co, Cu, Fe, Pb, Hg, Mo, Ni, Se, Ag, Tl, Th, U, and Zn, gross alpha and beta activities, and U and Th...
Cleveland, Danielle; Hinck, Jo Ellen; Lankton, Julia S. Chiroptera
With over 1300 species identified, bats represent almost one quarter of the world’s mammals (Fenton and Simmons 2014), bats provide important environmental services such as insect pest suppression, seed dispersal, and pollination and inhabit a wide variety of ecological niches on all continents except Antarctica. Over 150 species are listed as...
Farina, Lisa L.; Lankton, Julia S. Green tree frog (Hyla cinerea) and ground squirrel (Xerospermophilus spilosoma) mortality attributed to inland brevetoxin transportation at Padre Island National Seashore, Texas, 2015
On 16 September 2015, a red tide (Karenia brevis) bloom impacted coastal areas of Padre Island National Seashore Park. Two days later and about 0.9 km inland, 30–40 adult green tree frogs (Hyla cinerea) were found dead after displaying tremors, weakness, labored breathing, and other signs of neurologic impairment. A rainstorm, accompanied by high...
Buttke, Danielle E.; Walker, Alicia; Huang, I-Shuo; Flewelling, Leanne; Lankton, Julia S.; Ballmann, Anne E.; Clapp, Travis; Lindsay, James; Zimba, Paul V. Natural infections with Pigeon Paramyxovirus-1: Pathologic changes in Eurasian collared-doves (Streptopelia decaocto) and rock pigeons (Columba livia) in the USA: Data
We reviewed pathological findings and to a lesser extent epidemiological data from 70 free-ranging columbiforms naturally infected with Pigeon paramyxovirus-1 (PPMV-1) from 25 different PPMV-1 mortality events in columbiforms in the USA. In a subset of 17 birds from 10 of the studied outbreaks, we carried out immunohistochemistry targeting PPMV-1...

Pigeon paramyxovirus serotype 1 (PPMV-1) is a globally distributed, virulent member of the avian paramyxovirus serotype 1 serogroup that causes mortality in columbiformes and poultry. Following introduction into the United States in the mid-1980s, PPMV-1 rapidly spread causing numerous mortality events in Eurasian collared-doves (Streptopelia...

The risks to wildlife and humans from uranium (U) mining in the Grand Canyon watershed are largely unknown. In addition to U, other co-occurring ore constituents contribute to risks to biological receptors depending on their toxicological profiles. This study characterizes the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (...
