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., weather) variab
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 translocatio
Code to Analyze Occupancy Data for Dixie Valley Toads, Anaxyrus williamsi in Churchill County, Nevada from 2018 to 2021
-R code to create and fit dynamic occupancy models to Dixie Valley Toad survey data in JAGS and produce useful summaries of model results. This script will perform the Gibbs Variable Selection (GVS) using the initial set of environmental covariates, and then fit the "final" model using only important environmental covariates. The dynamic occupancy model is adapted from the model published by Duart
Science-based Management of Ravens Tool (SMaRT)
The Science-based Management of Ravens Tool (SMaRT) supports a science-based adaptive management framework that incorporates recent quantitative analyses and mapping products for addressing areas with elevated common raven (Corvus corax) numbers and minimizing potential adverse impacts to sensitive species, agricultural damage, and human safety (Dettenmaier et al. 2021). This is a web-based applic

"growth_analysis.R"
-An R script to fit the von Bertalanffy growth model to growth data
from San Francisco gartersnakes. The von Bertalanffy growth model is fit using JAGS software (Plummer 2003), and is based on the model presented in Armstrong and Brooks (2013).
"survival_analysis.R"
-An R script to fit the robust-design Cormack-Jolly-Seber model to capture-mark-recapture data from

Mojave Seed Menus: a new spatial tool for restoration software release v1.0
Mojave Seed Menus is a spatial decision-support tool designed to
help land managers create suitable seed mixes for restoration sites,
such as a burned area or other mapped spatial feature. The application
provides coverage for the Mojave Desert ecoregion.
Seed menus are based on a combination of habitat suitability models for
50 priority restoration plant species. Species are selected based on
