Diplotriaena obtusa (Nematoda: Diplotriaenidae) from barn swallows (Hirundo rustica) and cliff swallows (Petrochelidon pyrrhonota) collected during mortality events in the Upper Midwest, USA Diplotriaena obtusa (Nematoda: Diplotriaenidae) from barn swallows (Hirundo rustica) and cliff swallows (Petrochelidon pyrrhonota) collected during mortality events in the Upper Midwest, USA
Several mortality events involving barn swallows (Hirundo rustica) and cliff swallows (Petrochelidon pyrrhonota) were reported in the Upper Midwestern states in 2017 and 2018. Barn swallow mortality followed unseasonal cold snaps, with the primary cause of death being emaciation with concurrent air sac nematodiasis. Lesions in cliff swallows were consistent with blunt force trauma from...

Confirmed cases of Ophidiomycosis in museum specimens from the USA as early as 1945, United States Confirmed cases of Ophidiomycosis in museum specimens from the USA as early as 1945, United States
Ophidiomycosis represents a conservation threat to wild snake populations. The disease was reported in North America early in the 21st century, but the history of ophidiomycosis has not been investigated. We examined museum specimens and confirmed cases of ophidiomycosis >50 years before the disease’s reported emergence.

Pathology of Lagovirus europaeus GI.2/RHDV2/b (rabbit hemorrhagic disease virus 2) in native North American lagomorphs Pathology of Lagovirus europaeus GI.2/RHDV2/b (rabbit hemorrhagic disease virus 2) in native North American lagomorphs
Rabbit hemorrhagic disease, a notifiable foreign animal disease in the US, was reported for the first time in wild native North American lagomorphs in April 2020 in the southwestern US. Affected species included the desert cottontail (Sylvilagus audubonii), mountain cottontail (Sylvilagus nuttallii), black-tailed jackrabbit (Lepus californicus), and antelope jackrabbit (Lepus alleni)...

Investigation of algal toxins in a multispecies seabird die-off in the Bering and Chukchi seas Investigation of algal toxins in a multispecies seabird die-off in the Bering and Chukchi seas
Between 2014 and 2017, widespread seabird mortality events were documented annually in the Bering and Chukchi seas, concurrent with dramatic reductions of sea ice, warmer than average ocean temperatures, and rapid shifts in marine ecosystems. Among other changes in the marine environment, harmful algal blooms (HABs) that produce the neurotoxins saxitoxin (STX) and domoic acid (DA) have...

Diagnostic and field data from the Eastern Migratory Whooping Crane Population Diagnostic and field data from the Eastern Migratory Whooping Crane Population
Detailed data collected from the field and generated during diagnostic evaluation of whooping crane carcasses from the Eastern Migratory Population.
Histopathology of zebra finches (Taeniopygia guttata) orally exposed to clothianidin (ver. 2.0, October 2019) Histopathology of zebra finches (Taeniopygia guttata) orally exposed to clothianidin (ver. 2.0, October 2019)
This dataset reports select histopathological changes in liver, kidney, gonad, spleen, brain, heart, skeletal muscle, lung, or adrenal gland of zebra finches exposed to 15mg/kg, 18mg/kg, 30mg/kg, 60mg/kg, 75mg/kg, 125mg/kg, or 250mg/kg clothianidin (CTD) (with controls) by gavage, in water, or on millet seed either as a single dose or for 7 days. The goal of the project is to develop a...
Histopathology of American kestrels (Falco sparverius) exposed to brodifacoum Histopathology of American kestrels (Falco sparverius) exposed to brodifacoum
This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels exposed to the second-generation anticoagulant rodenticide brodifacoum (BROD). The goal of the study was to determine the toxic range of brodifacoum by feeding birds a diet containing 0.3, 1.0, or 3.0 ug BROD/g wet weight. Birds were necropsied and examined...
Histopathology of American kestrels (Falco sparverius) sequentially exposed to first and second generation anticoagulant rodenticides Histopathology of American kestrels (Falco sparverius) sequentially exposed to first and second generation anticoagulant rodenticides
This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels sequentially exposed to first and second generation anticoagulant rodenticides (FGAR and SGAR). The goal of the study was to determine the toxicity of sequential exposure to anticoagulant rodenticides (ARs) by evaluating FGAR-FGAR exposure (7 day...
Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium
This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6...
Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed
These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in soil, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation and soil. Radioactivities...
