Paranannizziopsis spp. associated with skin lesions in wild snakes in North America and development of a real-time PCR assay for rapid detection of the fungus in clinical samples Paranannizziopsis spp. associated with skin lesions in wild snakes in North America and development of a real-time PCR assay for rapid detection of the fungus in clinical samples
The emergence of ophidiomycosis (or snake fungal disease) in snakes has prompted increased awareness of the potential impacts of fungal infections on wild reptile populations. Yet, aside from Ophidiomyces ophidiicola, little is known about other mycoses affecting wild reptiles. The closely related genus Paranannizziopsis has been associated with dermatomycosis in snakes and tuataras in...
Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021 Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021
We compiled time series of egg mass counts (an index of adult female abundance) from Rana boylii populations in 36 focal streams and fit a Multiple Population Viability Analysis (MPVA) model to quantify how streamflow metrics, stream temperature, and surrounding land cover affect population growth. In addition, data on streamflow, stream temperature, and surrounding land cover for each...
Seasonal movements of mule deer and pronghorn in Wyoming, 2014-2021 Seasonal movements of mule deer and pronghorn in Wyoming, 2014-2021
USGS scientists evaluated the utility of hidden Markov movement models to characterize seasonal movements of mule deer (Odecoileus hemionus) and pronghorn (Antilocapra americana) that were tracked with GPS collars in Wyoming, USA, during 2014-2021. Data include step lengths and turning angles for individual animals at daily time-steps throughout the tracking period. Models demonstrated...
Example application of MetaIPM to the Illinois River Example application of MetaIPM to the Illinois River
This repository contains an example application of the `Meta-IPM` Python package (https://doi.org/10.5066/P9PW673G). The specific application focuses on the Illinois River using existing public data.
Indiana mussel metabolomics data analysis Indiana mussel metabolomics data analysis
This repository contains code to cluster a sample of Mussels based up their metabolic levels via Non-Metric Multidimensional Scaling (NMDS) and distance based-Redundancy Analysis (db-RDA). Mussel sample is broken down and examined by catch location, sex, and species. The code for this project assumes the reader is familiar with R and clustering techniques.
Characterization of occurrence and abundance of targeted metabolites in unionid mussels from three streams Characterization of occurrence and abundance of targeted metabolites in unionid mussels from three streams
The data consists of targeted metabolite analysis (using quadrupole time-of-flight mass spectroscopy;UHPLC-QTOF-MS) of hemolymph from two freshwater mussel species (Lampsilis cardium and L. siliquoidea) from three streams in Indiana. Concentrations of metabolites were modeled by species, stream and sex to determine the influence of each parameter.
