Olive ridley necropsy data for Salmonella study

Salmonella spp. are frequently shed by wildlife including turtles, but S. enterica subsp. enterica serovar Typhimurium or lesions associated with Salmonella are rare in turtles. Between 1996 and 2016, we necropsied 127 apparently healthy pelagic olive ridley turtles (Lepidochelys olivacea) that died from drowning bycatch in fisheries and 44 live or freshly dead stranded turtles from the west...

Predicted Shorelines for High Flows on the Colorado River Application

This application highlights modeled flows of the Colorado River for a discharge of 41,000 cubic feet per second (cfs) that is approximate to recent (2012 - 2018) and future anticipated water releases associated with a High Flow Experiments conducted from Glen Canyon Dam near Page, Arizona.  These data are to help visualize the water levels during High Flow Events in relation to other map...

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 insect-eating 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 one of four vaccine treatments or PBS as a control and...

Plague positive mouse fleas on mice prior to plague outbreaks in black-tailed and white-tailed prairie dogs

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) and high elevation Utah plots where plague was active were more frequently trapped in 2014 and 2015. In the dataset the...

DATA RELEASE - Predictive maps of 2D and 3D surface soil properties and associated uncertainty for the Upper Colorado River Basin, USA

Raster datasets are maps of soil surface properties that were used in analyzing different approaches for digital soil mapping. They include maps of soil pH, electrical conductivity, soil organic matter, and soil summed fine and very fine sand contents that were created using 2D and 3D modeling strategies. For each property a map was created using 2D and 3D approaches to compare the mapped...

LEAN-Corrected San Francisco Bay Digital Elevation Model, 2018

Lidar-derived digital elevation models often contain a vertical bias due to vegetation. In areas with tidal influence the amount of bias can be ecologically significant, for example, by decreasing the expected inundation frequency. We generated a corrected digital elevation mode (DEM) for tidal marsh areas around San Francisco Bay using the Lidar Elevation Adjustment with NDVI (LEAN) technique...
