Grfin Tools—Software Package and Runtime Documentation for Users Grfin Tools—Software Package and Runtime Documentation for Users
Grfin Tools (an acronym of Growth + flow + inundation) is a set of software tools for portraying areas potentially impacted by runout from landslides or inundation from geophysical mass-flows (such as debris flows) with or without growth as they travel. Grfin Tools allows users to assess the effects of a wide range of factors that can influence mobility. The software also enables runout
Contact rates for identifying interactions of white-tailed deer in a chronic wasting disease management area Contact rates for identifying interactions of white-tailed deer in a chronic wasting disease management area
Examinations of contact rates among white-tailed deer (Odocoileus virginianus; hereafter, deer) are important to applied management objectives given their societal value and disease transmission potential. This R script was used to curate the original GPS collar and capture data from Pennsylvania DMA2 in preparation for contact rates analysis.
Barry Arm landslide complex tsunami modeling scenarios, version 1.0.0 Barry Arm landslide complex tsunami modeling scenarios, version 1.0.0
This repository contains the code needed to reproduce computations presented in Barnhart and others (under review). This readme contains instructions for reproducing results and a list of the git hashes for each source repository used. Computation for this manuscript was done on the U.S. Geological Survey Denali High Performance Computer (Falgout and others, 2024). Barnhart, K.R., George...
Nonstationary demographic state-space models: R and JAGS code Nonstationary demographic state-space models: R and JAGS code
This repository contains R and JAGS code for fitting nonstationary demographic state-space models (NDSSM) to count-valued abundance data. Models use reduced dynamics but explicitly characterize growth rate distributions, including changepoints and/or volatility clustering for the timing and impacts of environmental stressors. Species fecundity is used to truncate growth rate...
cgsim: An R package for simulating conservation relevant outcomes for management actions, (version 1.0.2) cgsim: An R package for simulating conservation relevant outcomes for management actions, (version 1.0.2)
Wildlife conservation and management increasingly considers genetic information to plan, understand, and evaluate implemented population interventions. These actions commonly include conservation translocation and population reductions through removals. Change in genetic variation in response to management actions can be unintuitive due to the influence of multiple interacting drivers of...
The Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 The Precipitation Runoff Modeling System (PRMS) version 5.2.1.1
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow can be assessed with computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter, physical process-based modeling system developed to evaluate the response of...
