WHISPers stands for Wildlife Health Information Sharing Partnership - event reporting system. It is a web-based repository for sharing basic information about historic and ongoing wildlife mortality (death) and morbidity (illness) events. The system possesses a searchable archive of wildlife mortality and morbidity event data that is available to the public. The information is opportunistically collected and does not reflect all the mortality events that occur in North America.
The review provides an overview of the features of the North Sea and the Baltic Sea in their European geographical and socio-political context. To reach sustainability in the wider sense the common society has to meet the 7 tenets - that management actions have to be environmentally sustainable, economically viable, technologically feasible, socially desirable (or at least tolerable), legally permissible, administratively achievable and politically expedient. Each of these are explained and discussed using examples from the two seas including pollution control, physical resource exploitation (such as aggregates, habitat loss, renewable energy and oil and gas), and biological resources exploitation (fisheries and...

The diagnosis of bacterial disease in freshwater unionid mussels has been hindered by a lack of baseline information regarding the microbial communities associated with these animals. In this study, we cultured and identified bacteria from the hemolymph of stable mussel populations from the upper Mississippi River basin and compared results to mussel populations associated with a mortality event in the Clinch River, VA and TN. Several bacterial genera were consistently identified across mussel species and locations, appearing to be part of the natural bacterial flora. One noteworthy isolate was identified from the Clinch River. Yokenella regensbergei was found with relatively high prevalence during the mortality...

These data are associated with an article published in Global Ecology and Conservation (https://doi.org/10.1016/j.gecco.2020.e01173) that describes climate's cascading effects on disease, predation, and hatching sucess in the Yosemite toad (Anaxyrus canorus). The Yosemite toad currently is federally listed as threatened under the U.S. Endanered Species Act based upon reported population declines and vulnerability to climate and other global-change factors. The species occurs only in California’s central Sierra Nevada at medium to sub-alpine elevations. Lands throughout its range largely are protected from development, but climate and other global-change factors potentially can limit populations.

From 2003-2018, USGS researchers and collaborators conducted mark-recapture studies of the boreal toad at the Lost Trail National Wildlife Refuge in northwestern Montana, USA. The datasets included here contain information on individual toad capture history, body size, and disease status. These data were collected annually over the 16-year period at up to 11 breeding sites per year on the refuge. We include datasets for (1) male toad captures over time, (2) female toad captures over time, (3) male disease status (tested - positive or negative, or not tested in a given year), (4) all toad length and weight data over time, and (5) male toad size and body condition over time.

Native and introduced forest birds were captured and then released across the Hawaiian Islands to acquire a blood sample for obtaining DNA and test for exposure to avian malaria (Plasmodium relictum). A total of 2,945 samples were collected and analyzed for avian malaria prevalence from 39 species captured at 66 sites from Kauai, Oahu, Molokai, Maui, and Hawaii islands.
Land use was quantified within a 4-km radius around 36 apiaries in North Dakota, South Dakota, and Minnesota over two years, 2015-16 and 2016-17. The area (hectares) of Ag (corn, soy, small grains), Grass (pasture, grassland, fallow land, wildflowers, shrub land, and hay land), Wetlands (herbaceous and woody), and Bee crops (alfalfa, canola, sunflower) were quantified around each apiary in each year. Within each apiary, the average change in frames of adult bees among all colonies from June to September was calculated. Additionally, the average September Varroa mite infestation rate, the average adult population size during almond pollination, the count of colonies exhibiting queen events in September, and the count...
Of the 3 major factors (habitat loss, poisoning, and disease) that limit abundance of prairie dogs today, sylvatic plague caused by Yersinia pestis is the I factor that is beyond human control. Plague epizootics frequently kill > 99% of prairie dogs in infected colonies. Although epizootics of sylvatic plague occur throughout most of the range of prairie dogs in the United States and are well described, long-term maintenance of plague in enzootic rodent species is not well documented or understood. We review dynamics of plague in white-tailed (Cynomys leucurus), Gunnison's (C gunnisoni), and black-tailed (C ludovicianus) prairie dogs, and their rodent and flea associates. We use epidemiologic concepts to support...

ABSTRACT: The fungal pathogen Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, a disease implicated in amphibian declines on 5 continents. Polymerase chain reaction (PCR) primer sets exist with which amphibians can be tested for this disease, and advances in sampling techniques allow non-invasive testing of animals. We developed filtering and PCR based quantitative methods by modifying existing PCR assays to detect Bd DNA in water and sediments, without the need for testing amphibians; we tested the methods at 4 field sites. The SYBR based assay using Boyle primers (SYBR/Boyle assay) and the Taqman based assay using Wood primers performed similarly with samples generated in the laboratory (Bd spiked...

Current density of invasive species, insects, and disease within KM grid cell reporting units for the San Luis Valley - Taos Plateau Study Area. Attribute IID_C_CAT1 is valued along a scale of low current density (1) to high current density (4). This dataset is the result of a fuzzy model that integrates currently known and potential occurrences of invasive speices and forest insect pests and diseases. Data from a variety of sources were included, including LANDFIRE Existing Vegetation Types, LANDFIRE Succession Classes, SWReGAP Landcover Types, SLV weed management polygons, and U.S. Forest Service Forest Health survey areas.

This is part of a 3-tiered dataset consisting ofIDS_shapes: footprint polygon featuresIDS_attrib: attribute descriptions of polygonsIDS_rollup: lookup information for features that are summarized as a group (rollup)This dataset is a compilation of forest insect, disease and abiotic damage mapped by aerial detection surveys on forested areas in the United States. At this time, the National Aerial Survey Data Standards require only mortality and defoliation data be collected and reported. However, many cooperators collect data on other types of damage and therefore, the national database has been designed to accommodate these data. Low-level flights, typically 1,000 to 2,000 feet above ground level, are used to map...

Species loss can result in the subsequent loss of affiliate species. Though largely ignored to date, these coextinctions can pose threats to human health by altering the composition, quantity and distribution of zoonotic parasites. We simulated host extinctions from more than 1300 host–parasite associations for 29 North American carnivores to investigate changes in parasite composition and species richness. We also explored the geography of zoonotic parasite richness under three carnivore composition scenarios and examined corresponding levels of human exposure. We found that changes in parasite assemblages differed among parasite groups. Because viruses tend to be generalists, the proportion of parasites that are...
