Histopathology of bearded dragons (Pogona vitticeps) exposed to Nannizziopsis guarroi Histopathology of bearded dragons (Pogona vitticeps) exposed to Nannizziopsis guarroi
This work is part of a study demonstrating that the fungus Nannizziopsis guarroi is the cause of the disease known as yellow fungus disease in bearded dragons (Pogona vitticeps) by fulfilling Koch's postulates. In this study, bearded dragons were exposed to N. guarroi to assess gross and microscopic lesion development and the ability to re-culture the fungus from infected sites. At...
Data for food matrix reference materials for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotope-ratio measurements Data for food matrix reference materials for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotope-ratio measurements
An international project developed, quality-tested, and measured isotope-delta values of 10 new food matrix reference materials (RMs) for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotope-ratio measurements to support food authenticity testing and food provenance verification. These new RMs, USGS82 to USGS91, will enable users to normalize measurements of samples to isotope...

Data for Groundwater-Quality and Select Quality-Control Data for the Colorado Plateaus Principal Aquifer Data for Groundwater-Quality and Select Quality-Control Data for the Colorado Plateaus Principal Aquifer
Groundwater samples were collected from 60 public supply wells in the Colorado Plateaus principal aquifer. Water quality evaluations of groundwater for drinking water at public supply depths were made with the purpose of summarizing the current quality of source water (that is, untreated water) from public supply wells using two types of assessments; (1) status: an assessment that...
Estimated Use of Water by Subbasin (HUC8) in the Red River Basin, 2010 and 2015 Estimated Use of Water by Subbasin (HUC8) in the Red River Basin, 2010 and 2015
The Red River basin is one of several national "focus area studies" in the U.S. Geological Survey National Water Census. The objective of the National Water Census is to provide nationally-consistent base layers of well-documented data that account for water availability and use nationally. A focus area study (FAS) is a stakeholder-driven assessment of water availability in river basins...
Multibeam Bathymetry Data Collected in 2019 from Grand Bay and Point Aux Chenes Bay Alabama/Mississippi Multibeam Bathymetry Data Collected in 2019 from Grand Bay and Point Aux Chenes Bay Alabama/Mississippi
The U.S Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted an ellipsoidally referenced survey using a multibeam echosounder within Grand Bay and Point Aux Chenes Bay, Alabama/Mississippi May 7-10, 2019. The survey is a part of the Estuarine and Marsh Geology Research Project (EMRG) which focuses on evaluating the linkage between marsh shoreline...
