Scenario Analysis of Management Alternatives for Free-roaming Horse Populations (Version 1.0.0) Scenario Analysis of Management Alternatives for Free-roaming Horse Populations (Version 1.0.0)
PopEquus is a predictive modeling tool to support decisions related to the management of free-roaming horse populations. It permits the simulation and comparison of how management alternatives influence horse population size and metrics associated with management. This repository uses R scripts with predictive functions from the PopEquus model to simulate how management alternatives (e.g...
ADOM: A Data Orchestration Manager ADOM: A Data Orchestration Manager
A Data Orchestration Manager (ADOM) is a user interface designed to enforce data management goals by entwining and extending the open-source file management tool rclone. The rclone tool provides data movement and management functionality in and between supported end-user-defined endpoints, also known as remotes. ADOM takes rclone a step further by wrapping rclone functionality into USGS...
Modeling widespread declines in walleye recruitment following zebra mussel invasion in Minnesota lakes Modeling widespread declines in walleye recruitment following zebra mussel invasion in Minnesota lakes
Invasive zebra mussels (Dreissena polymorpha) alter lake ecosystems and can negatively affect first-year growth of walleye (Sander vitreus), potentially lowering walleye recruitment success. We quantified walleye recruitment responses to zebra mussel invasion in Minnesota lakes using data from 1,438 electrofishing surveys across 348 lakes collected between 1993 and 2019 to measure...
Accounting for spatio-temporal variation in catchability in joint species distribution models Accounting for spatio-temporal variation in catchability in joint species distribution models
1: Estimating relative abundance is critical for informing conservation and management efforts and for making inferences about the effects of environmental change on populations. Freshwater fisheries span large geographic regions, occupy diverse habitats, and consist of varying species assemblages. Monitoring schemes used to sample these diverse populations often result in populations...
Code for a hierarchical model of raven densities linked with sage-grouse nest survival to help guide management of subsidized avian predators, version 1.0 Code for a hierarchical model of raven densities linked with sage-grouse nest survival to help guide management of subsidized avian predators, version 1.0
This repository includes R code to conduct hierarchical density surface modeling of common raven (Corvus corax) point count data and hierarchical shared frailty modeling of Greater sage-grouse (Centrocercus urophasianus) nest fates. The model components are quantitatively linked, such that estimates of raven density from the hierarchical distance sampling component are spatially...
Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse
The Bi-State conservation planning tool provides a science-based approach for prioritizing pinyon (Pinus spp.) and juniper (Juniperus osteosperma, J. occidentalis), hereafter, 'conifer', removal to improve habitat for greater sage-grouse (Centrocercus urophasianus) in the Bi-State Distinct Population Segment (DPS, U.S. Fish and Wildlife Service 2010). Conifer negatively affects sage...
