This is the repository for an R Shiny App that allows users to create sea ice records for the Bering and Chukchi seas from diatom data. Users will upload a data set of diatom percentages and the app will return predictions of spring (March, April, May, June_ sea ice concentrations based on a generalized additive model of surface sediment assemblages in the Bering and Chukchi Seas. Please...

This software release contains the code for modeling and analysis of bat fatality data at a sample of wind energy facilities in the Upper Midwest United States. The model estimates total bat fatalities at each turbine across multiple wind energy facilities, years, and species of bats based on post-construction monitoring data with imperfect detection.

This repository contains the code for modeling and analysis of bat fatality data at a sample of wind turbine facilities across the United States. The software is written in R and includes hierarchical Bayesian n-mixture models implemented in JAGS to predict bat fatalities across wind facilities retrospectively from 2001-2024 and under future potential wind development build-out scenarios...

Observation of wild turkey (Meleagris gallopavo) are collected by many state wildlife agencies to monitor reproduction. This code demonstrates how to use generalized linear models to account for when and where data are collected, as well as how to combine data from multiple states to estimate parameters when data may be missing in some years. In addition, the code shows how to test for a...

**OptimTFE** is a spatial decision-support tool designed to help conservation practitioners identify priority recovery areas for species/taxonomic groups based on known location data, habitat suitability values, and other relevant data inputs. The optimTFE tool was developed to improve transparency, flexibility, and expert engagement throughout the spatial conservation prioritization...

Software release of 2023 Alaska NSHM input files for use with nshmp-haz.

The North American Bat Monitoring Program: R Data Connection Package can be used to extract and upload data to the NABat Monitoring Program through the GQL API. This software is written as a wrapper around the NABat GQL API. Documentation for the database and API can be found at https://sciencebase.usgs.gov/. This code includes the ability to reformat NABat data, upload NABat data...

This software release contains the code necessary to run the chronic wasting disease (CWD) and elk population models used to support the U.S. Fish and Wildlife Service decision on whether to continue to continue supplemental feeding of elk on the National Elk Refuge (NER). The models allow for five different management alternatives: continued feeding, reduced feeding, increased hunting...

This repository includes R code to run nest, brood, and adult hierarchical logistic exposure models, used for analyzing survival responses of Greater sage-grouse (Centrocercus urophasianus) to a suite of environmental covariates, with emphasis on precipitation and/or drought effects. An example population state-space model (the top model according to WAIC; see manuscript results and...

This software release contains the code necessary to produce the elk habitat selection models used to support the U.S. Fish and Wildlife Service (FWS) feeding decisions for the National Elk Refuge. This update provides additional analyses pertaining to an additional management scenario considered by FWS ('Alternative D').

Model space-time data with Gaussian processes. Geostat makes it easy to implement Gaussian Process (GP) models with complex covariance functions and has built-in capabilities for geoscience problems.

This software release contains a generalized workflow to setup particle tracking analyses to assess groundwater travel times at the Navy-Northrop-Grumman site, in Nassau County, New York. This approach uses the posterior "texture model" inset model described by Fienen and others (2024) and made available in Corson-Dosch and others (2023) that simulates groundwater flow in the sole-source...
