Inferring pathogen presence when sample misclassification and partial observation occur Inferring pathogen presence when sample misclassification and partial observation occur

This software contains four separate R scripts and one Matlab script that comprise an analysis to estimate the posterior probability of pathogen presence when sample misclassification and partial observations occur. We develop a Bayesian hierarchal framework that accommodates false negative, false positive, and uncertain detections and apply this framework to a case study of the fungal...

inlcolor---Color palettes for the U.S. Geological Survey Idaho National Laboratory Project Office inlcolor---Color palettes for the U.S. Geological Survey Idaho National Laboratory Project Office

The R package inlcolor provides access to a variety color schemes. Used to support packages and scripts written by researchers at the United States Geological Survey (USGS) Idaho National Laboratory Project Office (INLPO). Key features of this package are (1) a simple and consistent API, (2) support for qualitative, diverging, and sequential color schemes, (3) support for combining color...

Integrated Software for Imagers and Spectrometers Integrated Software for Imagers and Spectrometers

A software library and set of tools to support ingestion, processing, and analysis of planetary science data. Version 8.0.2

Interpolating missing water quality data Interpolating missing water quality data

This repository contains analysis codes to interpolate missing data from the Upper Mississippi River LTRM dataset.

Joint Ecosystem Modeling (JEM) Restoration Runs R Library Joint Ecosystem Modeling (JEM) Restoration Runs R Library

restoration_runs is a library of R-language scripts used to summarize/post-process output of Joint Ecosystem Modeling (JEM; https://jem.gov/) models used in Everglades restoration planning for projects such as the Lake Okeechobee System Operating Manual (LOSOM) and the Western Everglades Restoration Project (WERP). The scripts summarize model output and create graphs and maps for each...

Modeling widespread declines in walleye recruitment following zebra mussel invasion in Minnesota lakes Modeling widespread declines in walleye recruitment following zebra mussel invasion in Minnesota lakes

Invasive zebra mussels (Dreissena polymorpha) alter lake ecosystems and can negatively affect first-year growth of walleye (Sander vitreus), potentially lowering walleye recruitment success. We quantified walleye recruitment responses to zebra mussel invasion in Minnesota lakes using data from 1,438 electrofishing surveys across 348 lakes collected between 1993 and 2019 to measure...

NO3GWT version 1.0.0 NO3GWT version 1.0.0

A groundwater Nitrate Decision Support Tool (GW-NDST) for wells in Wisconsin was developed to assist resource managers with assessing how legacy and possible future nitrate leaching rates, combined with groundwater lag times and potential denitrification, influence nitrate concentrations in wells (Juckem et al. 2024). The GW-NDST was reviewed and approved by the journal via this official...

Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS) Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS)

The Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS) model is a framework to simulate the erosion of a closed-basin coastline through time by fetch-dependent erosion or uniform erosion. The model is written in MATLAB and the MATLAB Image Processing Toolbox and a MEX compiler are required.

occupancyTuts: A package for learning occupancy modeling with RPresence occupancyTuts: A package for learning occupancy modeling with RPresence

Understanding how species are distributed in both space and time is a central question in ecology. Seemingly simple questions such as “How many individuals live in a particular patch?”, “Is a patch occupied by a target species?”, “How many species are there?”, and “what factors shape these pattern?” are questions routinely asked by ecologists. The tutorials in occupancyTuts will...

Optimal harvest of a theoretical population under system change Optimal harvest of a theoretical population under system change

This code solves optimal harvest policies under different scenarios of system change, represented as changes in demographic parameters over time. This document contains code to solve policies using backwards iteration stochastic dynamic programming, project populations forward to simulate the policies, and generate figures.

Per- and Polyfluoroalkyl Substances (PFAS) in U.S. Tapwater: Comparison of Public-Supply and Underserved Private-Well Exposures and Associated Health Implications Per- and Polyfluoroalkyl Substances (PFAS) in U.S. Tapwater: Comparison of Public-Supply and Underserved Private-Well Exposures and Associated Health Implications

This software involves files to fit the statistical models described in Smalling et al. Specifically, there are R scripts and associated stan model files (when appropriate) for comparing PFAS concentrations among public-supply and private-wells and as a function of geospatial predictor variables. There is also an R script for modeling the number of PFAS chemicals detected among water...
