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...
PopEquus: A Predictive Modeling Tool to Support Management Decisions for Free-roaming Horse Populations, Version 1.0.1 PopEquus: A Predictive Modeling Tool to Support Management Decisions for Free-roaming Horse Populations, Version 1.0.1
PopEquus is a website application that can be used to understand trade-offs and inform decisions in free-roaming horse (Equus caballus) population management. The application (https://rconnect.usgs.gov/popequus/) contains a predictive population modeling tool that can be used to simulate how different management actions drive changes in horse population size, while measuring management...
rsgis v1.0 rsgis v1.0
rsgis: A package to facilitate greater sage-grouse management in the western US The rsgis package centralizes several publicly available geospatial datasets that are essential to mapping and modeling for Greater sage-grouse (Centrocercus urophasianus) management applications, including important habitat and breeding areas for sage-grouse and political/regional boundaries. To cite the...
raventools v1.0 raventools v1.0
raventools: A package to facilitate raven management in the western U.S. The raventools package centralizes several publicly available geospatial datasets that are essential to mapping and modeling for common raven (Corvus corax) management applications, including raven occurrence and density data, sensitive species distribution data, raven subsidy data, and Greater sage-grouse...
Code to analyze multi-state, multi-scale dynamic occupancy models for amphibians in Yosemite National Park Code to analyze multi-state, multi-scale dynamic occupancy models for amphibians in Yosemite National Park
The purpose of this study was to evaluate how extreme variation in precipitation in the Sierra Nevada of California, USA, in the early 21st Century affected adult occupancy and the probability of reproduction of amphibians. The study used a 15-year data set to relate site characteristics to initial probability of occurrence of adults, and additional site-specific and dynamic (e.g...
Code to analyze survival data for Giant gatersnakes, Thamnophis gigas in Sacramento County, California from 2018 to 2021 Code to analyze survival data for Giant gatersnakes, Thamnophis gigas in Sacramento County, California from 2018 to 2021
The purpose of this study was to estimate the survival of giant gartersnakes (Thamnophis gigas) prior to and following translocation, as well as to evaluate the use of captive rearing as a conservation tool for giant gartersnakes. We used Kaplan-Meier and Cox Proportional Hazards models to estimate survival rates and estimate the effects of group identity (marsh donor, rice donor, and...
