Chemically intensive crop production depletes wildlife food resources, hinders animal development, health, survival, and reproduction, and it suppresses wildlife immune systems, facilitating emergence of infectious diseases with excessive mortality rates. Gut microbiota is crucial for wildlife’s response to environmental stressors. Its composition and functionality are sensitive to diet changes and environmental pollution associated with modern crop production. In the study entitled Exposure to crop production alters cecal prokaryotic microbiota, inflates virulome and resistome in wild prairie grouse we use shotgun metagenomics to demonstrate that exposure to modern crop production detrimentally affects cecal...

Decades of poor reproductive success and young-of-the-year recruitment, in addition to adult mortality, has led to a decline in the smallmouth bass (SMB) population in subwatersheds of the Potomac River. Previous studies have identified numerous biologic and environmental stressors associated with negative effects on SMB health. To better understand the impact of these stressors, the current study was conducted from 2013-2019 to identify temporal changes associated with SMB reproductive health. Grab surface water samples were collected and analyzed for over 300 organic contaminants, including pesticides, phytoestrogens, pharmaceuticals, hormones and total estrogenicity (E2Eq). Adult SMB were collected and sampled...

The data were gathered as part of a long-term, seasonal assessment of estrogenicity in selected locations within Pennsylvania from 2012-2017. Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen. A total of 193 grab water samples were collected during this time of which 41% had EEQ above the limit of detection. The maximum estrogen equivalents (EEQ) measured was 5.44 ng EEQ/ L, while the median concentration was 0.44 ng/L. POCIS samplers were deployed at a number of sites to determine time-weighted estrogenicity between 2014 and 2017. A total of 150...

Histopathological assessments of young-of-the-year smallmouth bass (YOY SMB) in the Susquehanna River drainage identified a high prevalence of the myxozoan Myxobolus inornatus. This myxozoan infects the connective tissue of the muscle below the skin but is sometimes observed in the esophagus and buccal cavity. In some instances, shallow infections cause breaks in the skin which could increase the chance of opportunistic bacterial infections. Several microbial pathogens including Flavobacterium columnare, Aeromonas spp. and largemouth bass virus (LMBV) have also been cultured from clinically diseased YOY. A multiplex fluorescence in situ hybridization (FISH) assay was developed to determine potential co-localization...

In the fall of 2005, dead and dying great blue herons (Ardea herodias) exhibiting emaciation, lethargy, inability to fly and a hard abdomen (steatitis confirmed at necropsy) were observed at Poplar Island and nearby Coaches Island (Rattner et al. 2006). Birds were hand captured at or near impoundments (cells) and ponds that contained large algal blooms, and because of poor prognosis were euthanized. Seemingly healthy great blue herons were subsequently collected at Blackwater National Wildlife Refuge. Blood and fecal samples were collected, and submitted to Antech Diagnostics (Lake Success, New York) for Avian/Exotic Combined Blood Count, Comprehensive Avian Chemistries, Fecal Cultures and Vitamin E analysis. Liver...

In 2016, smallmouth bass were collected from three sites in the Lake Erie drainage in Erie County, Pennsylvania and an out-of-basin site in the Allegheny River drainage in order to assess reproductive health and identify endocrine disruption responses. Pieces of liver and gonad were taken in Z-Fix and RNALater for histology and transcript abundance analysis. A landscape analysis was conducted for the immediate and upstream catchments with 2016 land cover data. Correlations between biological variables and transcripts were made in addition to differences between sites. The results showed that males had biological variables that correlated with transcripts associated with endocrine disruption and a high rate of testicular...

A number of brominated flame retardants (BFRs) have been reported to interfere with the thyroid signaling pathway and cause oxidative stress in birds, yet the underlying shifts in gene expression associated with these effects remain poorly understood. In this study, we measured hepatic transcriptional responses of 31 genes in American kestrel hatchlings following in ovo exposure to one of three high-volume alternative BFRs: 1,2-bis(2,4,6-tribromophenoxy) ethane (BTPBE), bis(2-ethylhexyl)-2,3,4,5-tetrabromophthalate (TBPH), or 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EHTBB). Hatchling kestrels exhibited shifts in the expression of genes related to oxidative stress (CYP, GSTA, SOD, GPx), thyroid hormone metabolism...

Data described herein was collected by USGS personnel and the project funded by USGS and the National Park Service (Catoctin Mountain Park) through a FY14 NRPP project involving both agencies and developed to detect the presence and prevalence of ranavirus and chytrid pathogens among amphibians of Catoctin Mountain Park (CATO). Supplemental molecular analyses were performed on behalf of LSC by the molecular biology laboratory at Hagerstown Community College whereby students performed the molecular diagnostic testing and provided the raw data to LSC for analysis. There is no data sharing agreement specifying ownership, but the data was presented to the NPS CATO staff to help guide their management decision-making...

Data described herein was collected by USGS personnel and the project funded by USGS. Northern snakehead specimens were collected from the Potomac River and its tributaries by regional natural resource management agencies in the course of their field investigations working with this priority invasive aquatic species. Specimens were provided to USGS for the purpose of conducting health related assessments of northern snakehead in the region, with approximately 90 specimens evaluated grossly and histologically for the presence of lesions and abnormalities. Data presented here was collected seasonally (spring through fall) in 2006 and from 2015 to 2017. Data for each specimen includes date and location of collection,...

The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and breeding and wintering grounds creates conditions to potentially infect millions of birds annually. The mallard is the most abundant of all duck species and migratory across much of its range. Here we characterized enteric viral pathogens from the cecum of 16 captive raised mallards (Anas platyrhynchos) from Wisconsin, USA using...

There is an increasing emphasis on effects-based monitoring to document responses associated with exposure to complex mixtures of chemicals, climate change, pathogens, parasites and other environmental stressors in fish populations. For decades aquatic monitoring programs have included the collection of tissues preserved for microscopic pathology. Consequently, formalin-fixed, paraffin-embedded (FFPE) tissue can be an important reservoir of nucleic acids as technologies emerge that utilize molecular endpoints. Despite the cross-linking effects of formalin, its impact on nucleic acid quality and concentration, amplification, and sequencing are not well described. While fresh-frozen tissue is optimal for working with...
