**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 v1.2.0 can be used to extract and analyze data from the NABat Monitoring Program through the GQL API. This software is written as a wrapper around the NABat GQL API. Updates to this package include the ability for users to query, analyze, and generate reports for multiple NABat projects simultaneously, the addition of...

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').

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...

This repository contains data and code supporting the Gilbert et. al manuscript entitled, "Reproductive habitat mismatch influences chytrid infection dynamics in a tropical amphibian community". The objective of the paper is to identify the influence of life history, rainfall, and habitat on chytrid infection dynamics in a frog community in Brazil’s Atlantic Forest. The code (see...

This project compared methods for estimating large scale patterns of animal resource selection and species distribution to demonstrate the benefits of marginalized space-time point process models.

This standalone software application provides an integrated set of tools for inferring river discharge Q from remotely sensed data based on critical flow theory, a method introduced by Legleiter et al. (2025). This approach can yield accurate streamflow estimates in rivers with well-defined standing wave trains, referred to as undular hydraulic jumps (UHJ's). Once an image with clearly...

SURF is an algorithm to generate 3D fault models. This algorithm utilizes open-source, well known and documented packages, to generate fault models that require very few user input parameters.

Land managers seek to understand whether treatments they implement effectively achieve their goals to support, or at least not negatively impact, species of concern. This power analysis identifies minimum data collection needs to estimate treatment impacts when baseline species community information is lacking, and when there is significant risk of violating the species exchangeability...
