R code for calculating imperilment of freshwater fish with a Bayesian belief network R code for calculating imperilment of freshwater fish with a Bayesian belief network

This R script is reproduces a Bayesian belief network built within the propriety software program, Netica. The R- and Netica-based belief networks were used in Dunn and Schumann et al. (in press), which presents an approach for calculating imperilment of freshwater fishes.

Microsatellite genotypes and metadata for white-tailed deer samples from the Mid-Atlantic region of USA Microsatellite genotypes and metadata for white-tailed deer samples from the Mid-Atlantic region of USA

Dataset containing information for white-tailed deer samples from Ohio, Pennsylvania, Maryland, Virginia and New York, genotyped for 11 microsatellites markers. Marker OvirQ should not be used as it presents alleles inconsistent with reported pattern, with some alleles separated by only 1 base pair and inconsistent between runs. Projected coordinates representing sampling location are in...

Population Viability Model for Spot-tailed earless lizard Population Viability Model for Spot-tailed earless lizard

Code for simulating Spot-tailed earless lizard populations under habitat loss and road mortality threats in central Texas

Predicting fish responses to climate change using a joint species, spatially dependent physiologically guided abundance model Predicting fish responses to climate change using a joint species, spatially dependent physiologically guided abundance model

Predicting the effects of warming temperatures on the abundance and distribution of organisms under future climate scenarios often requires extrapolating species-environment correlations to thermal conditions not currently experienced by a species or to temperatures that exceed the range of observed data. For poikilotherms, incorporating species’ thermal physiology to inform...

Population genetic structure of white-tailed deer using microsatellites i the Mid-Atalntic region Population genetic structure of white-tailed deer using microsatellites i the Mid-Atalntic region

Results of 11 microsatellites for white-tailed deer collected in Maryland, New York, Ohio, Pennsylvania, and Virginia from 2014 to 2022 for genetic analysis. In this project we assessed genetic structure using different analyses, and evaluated the performance of assignment tests to correctly match deer to origin (defined as genetic cluster, state or physiographic province). This...

Chronic Wasting Disease Surveillance Optimization Software Version 2 Chronic Wasting Disease Surveillance Optimization Software Version 2

The Chronic Wasting Disease Surveillance Optimization Software Version 2 computes sampling recommendations to detect chronic wasting disease (CWD) in white-tailed deer (Odocoileus virginianus). Driven by a combinatorial optimization algorithm, the software maximizes the return-on-investment to the wildlife agency while keeping the overall surveillance program within budget. The software...

Optimal harvest of a theoretical population under system change Optimal harvest of a theoretical population under system change

This code solves optimal harvest policies under different scenarios of system change, represented as changes in demographic parameters over time. This document contains code to solve policies using backwards iteration stochastic dynamic programming, project populations forward to simulate the policies, and generate figures.

Code for: Small enzootic survival costs mask the potential for long-term population size suppression Code for: Small enzootic survival costs mask the potential for long-term population size suppression

This repository contains all of the scripts to reproduce the analyses, figures, and tables associated with the manuscript Glorioso et al. in review. The scripts are organized into folders, and the folders are numbered in the order in which they should be executed. Briefly, there are six folders that do the following: (1) format the data, (2) fit the model, (3) run the population...

whitetailedSIRS: A package to project SARS-CoV-2 outbreak dynamics in white-tailed deer whitetailedSIRS: A package to project SARS-CoV-2 outbreak dynamics in white-tailed deer

This software release contains several R scripts that generate epidemic projections of SARS-CoV-2 in white tailed deer populations using a Susceptible-Infected-Recovered-Susceptible (SIRS) modeling framework. We provide a workflow of vignettes used in Rosenblatt et al. In Prep and Cook et al. In Prep. Users are able to specify transmission parameters for human-deer and deer-deer...

Hunter and prey linked population models Hunter and prey linked population models

Herein we present a simulation model to predict future prey and hunter populations in a stochastic population simulation model. In the simulation script the two populations (prey and hunters) are linked through feed back functions, where the hunters can affect the prey abundance through harvest rate and harvest success functions, and the prey affects hunter population retention and...

Change-point models for identifying single behavioral transitions in wild animals Change-point models for identifying single behavioral transitions in wild animals

We present two change-point models for identifying singular changes in movement behavior: a location-based change-point model (LCPM) and a movement metric-based change-point model (MMCPM). This software includes R scripts to: 1) run both the LCPM and MMCPM on telemetry data in a Bayesian hierarchical framework using NIMBLE (mmcpm.R and lcpm.R), 2) generate realistic movement behavior...

Input for Habitat Risk Software Input for Habitat Risk Software

Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy that was first detected in captive cervids in Colorado, United States (US) in 1967, but has since spread into free-ranging white-tailed deer (Odocoileus virginianus) populations across the US and Canada. In some areas, the disease is considered endemic in wild deer populations, and governmental wildlife agencies...
