Code to examine habitat selection and survival of greater sage-grouse in Nevada and northeastern California Code to examine habitat selection and survival of greater sage-grouse in Nevada and northeastern California
This repository centralizes R code used to examine habitat selection and survival of greater sage-grouse (Centrocercus urophasianus) during multiple seasons and life stages, utilizing data collected from a wide range of study sites in Nevada and California, USA. The R script "selection_model.R" provides code for a GLMM framework with regularization within a Bayesian modeling environment...
NHM-Assist NHM-Assist
NHM-Assist is a collection of python workflows presented in Jupyter notebooks for evaluating, running and interpreting National Hydrologic Model (NHM) domains using pywatershed. NHM-Assist allows users to: evaluate hydrofabric element connections such as hydrologic response unit connections to streamflow segments, segment routing order, and gage placement accuracy; display NHM domain...
NPS Stream Navigability Model NPS Stream Navigability Model
This code release fits a Bayesian logistic regression model to predict the probability that stream segments flowing through National Park lands in Alaska are considered navigable, based on slope (drop in elevation / segment length) and Strahler stream order, an ordinal metric with values ranging from 1-6. The model uses existing navigability determinations for a subset of stream segments...
Software for computations for compositional data analysis Software for computations for compositional data analysis
There exist at least two R packages for analysis of compositional data (Templ and others, 2023; van den Boogaart, 2024). Both packages have many functions for various types of analysis. Nonetheless, a package that performs just the computations for compositional data is needed for at least two reasons: First, such a basic package can be incorporated into other packages that perform...
Synthetic Checkpoint Generation Software Synthetic Checkpoint Generation Software
This software automatically generates synthetic elevation checkpoints suitable for assessing the vertical error on remotely-sensed topographic data such as Digital Elevation Models (DEMs), Digital Surface Models (DSMs), and point clouds. The software ingests a user-provided timeseries of DEMs, a road polyline dataset, and an impervious surface classification in order to place synthetic...
Shortnose Sturgeon Abundance Model Shortnose Sturgeon Abundance Model
R Code to run shortnose sturgeon population estimates for Higgs et al. 2025 The purpose of this software is to estimate the abundance of overwintering shortnose sturgeon using acoustic telemetry and side-scan sonar data. The code is based on work conducted on the Hudson River, New York, but could be readily adapted to other applications with a similar study design.
