Data and Tools

The integrated, interdisciplinary science branches of the USGS National Wildlife Health Center (NWHC) develop various data and tools to help understand the dynamics of diseases on wildlife populations. Below are scientific data, data portals, and tools available from the NWHC.

Experimental infection of Tadarida brasiliensis with the fungus that causes white-nose syndrome: hibernation data

This dataset includes skin temperatures of twelve Tadarida brasiliensis held in environmental chambers maintained at 7.7 (SD 0.9) °C and 91.8 (SD 0.8) % relative humidity to induce and support hibernation for up to 3 months. Bats were randomly assigned to infected and control groups at the start of the experiment and infected with conidia of Pseudogymnoascus destructans or a sham t

Sylvatic plague vaccine field trials flea data

These data were collected as part of a field trial to test the efficacy of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available sites at each location. At least 1 week and no more than 2 months post-baiting each year, local collaborators captured, marked and sampled prairie dogs for a minimum of 3 trap days. Both...

Impact of the oral Sylvatic Plague Vaccine on Non-target Small Rodents: Data

In 2013, a large blinded, paired placebo-controlled field trial for the prairie dog oral sylvatic plague vaccine started in the Western US. On 17 paired plots, vaccine and placebo plots, small rodents were trapped annually for 3-5 consecutive nights (when weather allowed). Up on capture, we documented the trap numbers and the processed animals. We noted standard biological informati

Occurrence of Chlamydia sp in apparently healthy birds associated with a mortality event caused by chlamydiosis: Data

These data sets are is a compilation of bird and environmental samples obtained from 6 sites in Maricopa County, Arizona on the dates shown. Sites were only visited and sampled if they had Rosy-cheeked lovebirds coming to bird feeders at the location and with the permission of the property owner. Two swab samples were obtained from each captured bird and 3 swab samples were collected from the...

Corallimorph Invasion Palmyra: Data

In 2007, a phase shift from corals to corallimorpharians (CM) was documented at Palmyra Atoll, Line Islands, centered around a shipwreck. Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency o

Northern Sea Otter Aging Criteria: data

Measurement of skull ossification patterns is a standard method for aging various mammalian species and has been used to age Russian, Californian, and Alaskan sea otter populations. Cementum annuli counts have also been verified as an accurate aging method for the Alaskan sea otter population. In this study, cementum annuli count results and skull ossification patterns were compared as me...

West Nile virus susceptibility of American singer canaries: Data

Three datasets are included: 1) survival of domesticated canaries and American crows following sub-cutaneous challenges ranging from 101 – 105 plaque forming units of West Nile virus. 2) Arbitrary units of WNV detected by RT-PCR or plaque forming units of WNV cultured in vero cells in 4 separate studies. Culture results are indicated for each day post WNV challenge. 3) Weight (m

Weighted Surveillance for Detection of Chronic Wasting Disease

This application provides an easy-to-use interface for conducting weighted surveillance for chronic wasting disease (CWD) in white-tailed deer populations. The first tool called 'Design' is used for planning weighted surveillance activities. The second tool called 'Estimation' is for use after sampling for CWD detection has occurred and no positive cases were found.
