This software fits models using iNaturalist data to compare the effectiveness of various strategies for improving model performance.

A collection of Jupyter notebooks that provide an end-to-end workflow for assessing montane meadow ecosystems using remote sensing data. The analysis integrates lidar-derived digital elevation models (DEMs), aerial multi-spectral imagery (NAIP), Sentinel-2 multispectral data, NOAA climgrid data, and global surface water data (JRC) to quantify stream characteristics, vegetation structure...

This software product displays estimated nesting dates for grassland-nesting birds in the midcontinental region of North America.

This repository contains scripts used to generate daily probabilistic tephra-fall maps. It was developed for Mount Spurr, but input files and scripts can be modified for other volcanoes as necessary.

The Surrogate Analysis and Index Developer (SAID) 2.0 tool is a Python port of the Matlab application SAID 1.1. It was developed by the USGS to assist in creating linear regression models that relate constituent and surrogate parameters. SAID provides visual and quantitative diagnostics to the user. The tool also optionally processes acoustic parameters to be used as explanatory...

GSFLOW is a coupled Groundwater and Surface-Water Flow model based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS; Markstrom and others, 2015) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW- 2005, Harbaugh, 2005; MODFLOW-NWT, Niswonger and others, 2011). In addition to the basic PRMS and MODFLOW simulation methods...

MODFLOW-NWT is a Newton formulation for MODFLOW-2005. MODFLOW-NWT is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation. MODFLOW-NWT must be used with the Upstream-Weighting (UPW) Package for calculating intercell conductances in a different manner than is done in the Block-Centered Flow...

This code provides a simple quantitative demonstration of an imagined land acquisition problem. Conservation results (i.e., benefit or reward) is evaluated under three competing decision models and varying degrees of ecological non-stationarity. The decision models reflect a spectrum of accommodating time-dependence into decision making: an optimal, fully time-dependent Markov Decision...

The vast majority of qPCR practitioners rely on either manual interpretation of fluorescence curves or automated interpretation using manufacturers default software and settings associated with the thermal cyclers used to generate the data. This practice has three major vulnerabilities: 1. Manufacturers use proprietary algorithms that obscure transparency and impede validation. 2...

This software release contains Program R script files where each script file completes a different step of the analysis of movement tracking data to assess daily activity budgets, foraging habitat use, and foraging success of Hudsonian Whimbrel (Numenius hudsonicus) while on migratory stopover in South Carolina, USA.
