PWFDF Data Specification PWFDF Data Specification
This is a permanent record of all current and former versions of the PWFDF data specification. The spec describes: the organization of assessments on ScienceBase, ScienceBase metadata unique to the collection, and the files, data, and metadata contained within individual assessments.
A decision support tool for assessing current and future occupancy trends for boreal toads in the Southern Rocky Mountains A decision support tool for assessing current and future occupancy trends for boreal toads in the Southern Rocky Mountains
This is repository contains all publicly-released code and data supporting the Southern Rocky Mountains boreal toad decision support tool, which was developed as a part of a North Central Climate Adaptation Science Center-funded project entitled “A framework for guiding management decisions for amphibians in an uncertain future”, by Dr. Amanda M. Kissel (USGS), Dr. Erin Muths (USGS), Mae...
R code for the workflow and analysis of spatio-temporal analysis of smallmouth bass (Micropterus dolomieu) growth in Pennsylvania Rivers R code for the workflow and analysis of spatio-temporal analysis of smallmouth bass (Micropterus dolomieu) growth in Pennsylvania Rivers
Using a 36-year dataset of smallmouth bass length-at-age, we assess the effect of population density, average critical period temperature, and average spring flow rate on early life growth rate. We also looked at how a disease outbreak in 2004 impacted early life growth rates in reaches with and without the disease. The code in this release provides the R scripts to perform this analysis...
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...
