wren: water-quality regression tools wren: water-quality regression tools

An R shiny application to organize and streamline the process of regression model development using time series data. An interactive browser interface allows users to evaluate potential variables, compare models, and output summary documents compiling descriptive graphs and statistics for archival purposes. The application allows for the processing of left-censored response variables...

AMMonitor: Remote monitoring of biodiversity in an adaptive framework. Version 2.0.0 AMMonitor: Remote monitoring of biodiversity in an adaptive framework. Version 2.0.0

Amid climate change and rapidly shifting land uses, effective methods for monitoring natural resources are critical to support scientifically-informed resource management decisions. The practice of using Autonomous Monitoring Units (AMUs) to monitor wildlife species has grown immensely in the past decade, with monitoring projects across species from birds, to bats, amphibians, insects...

A Long Short Term Memory model for predicting daily lake ice cover changes in the Northern Hemisphere A Long Short Term Memory model for predicting daily lake ice cover changes in the Northern Hemisphere

This software release includes the python scripts and jupyter notebooks of collecting remote-sensed lake ice cover data, training & validating a lake ice model and visualizing the model output.

A ‘How-to’ Guide for Estimating Animal Diel Activity Using Hierarchical Models A ‘How-to’ Guide for Estimating Animal Diel Activity Using Hierarchical Models

We provide R Markdown files that are built by Bookdown to create a tutorial (HTML) that contains step-by-step examples on how to use trigonometric and cyclic cubic spline hierarchical models to analyze animal diel activity patterns from time-stamped data.

Agisoft Metashape Alignment Helper Version 1.0 Agisoft Metashape Alignment Helper Version 1.0

The Alignment Helper is a GUI tool designed to be embedded in the Agisoft Metashape application. The Alignment Helper was written in support of a diver-based structure-from-motion data processing workflow and was built to facilitate proper alignment of Metashape models with the local grid coordinate system.

Alligator snapping turtle population simulation model developed in support of the Species Status Assessment Alligator snapping turtle population simulation model developed in support of the Species Status Assessment

This software release contains six R scripts that comprise a population viability analysis for the alligator snapping turtle (Macrochelys temminckii). To predict numbers of M. temminckii in the future, we constructed a female-only, stage-structured matrix projection model. We incorporated multiple types of uncertainty into the simulation model, including parametric uncertainty and...

AMMonitor: Remote monitoring of biodiversity in an adaptive framework. Version 2.1 AMMonitor: Remote monitoring of biodiversity in an adaptive framework. Version 2.1

Amid climate change and rapidly shifting land uses, effective methods for monitoring wildlife are critical to support scientifically-informed resource management decisions. As such, monitoring is motivated by ecological hypotheses or natural resource management objectives. The practice of using Autonomous Monitoring Units (AMUs) such as trail cameras or audio recorders to monitor...

Analysis of data for Effects of formaldehyde (Parasite-S) on biofilter nitrification from a cold- and a warm freshwater RAS Analysis of data for Effects of formaldehyde (Parasite-S) on biofilter nitrification from a cold- and a warm freshwater RAS

This repository contains the code used to analyzed the water quality from a formalin study. We examined how formalin affected the total nitrogen and nitrite nitrogen in water that was passed through a biofilter.

Analysis of occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA Analysis of occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA

These data were collected to test whether presence-absence surveys can aid in the identification of nesting sites for the Marbled Murrelet (Brachyramphus marmoratus), a threatened seabird that nests in older-aged forests along the Pacific Coast. The code presented here utilizes four data tables (csv documents) which are formatted according to tidy data principles. Those files are also...

Aquaculture and Irrigation Water Use Model 2.0 Software Aquaculture and Irrigation Water Use Model 2.0 Software

The Mississippi Alluvial Plain (MAP) is one of the most productive agricultural regions in the US and extracts more than 11 km3/year for irrigation activities. The heavy drivers of groundwater use are aquaculture and crops, which include rice, cotton, corn, and soybeans (Wilson, 2021). Consequently, groundwater-level declines in the MAP region (Clark and others, 2011) pose a substantial...

ARCHI: Automated Regional Correlation Analysis for Hydrologic Record Imputation, v1.0.0 ARCHI: Automated Regional Correlation Analysis for Hydrologic Record Imputation, v1.0.0

Welcome to Automated Regional Correlation Analysis for Hydrologic Record Imputation (ARCHI). ARCHI provides a workflow and interactive platform for regional-scale hydrologic record imputation. ARCHI allows users to aggregate, visualize, and impute records with irregular monitoring frequency at annual, seasonal, monthly, weekly, and daily timesteps. Missing data at “target” sites are...
