Evaluation of DNA yield from various tissue and sampling sources for use in single nucleotide polymorphism panels
R code to test for differences in DNA yield from of eight sample categories to gain insights into which provided adequate DNA to be used in ddRADseq or already developed SNP panels. We calculated mean, median and standard deviation with package psych using the describe() function. Additionally, we generated boxplots using package ggplot2 where the quantity for each tissue sample is categorized by
Application of the SEICarP Model to the Illinois River
This repository contains code to run the Spatially Explicit Invasive
Carp Population (SEICarP) model in the Illinois Rive.
The code uses the `SEICarP` R package.
The code for this project assumes the reader is familiar with R,
population modeling, and quantitative fisheries methods.
SEIcarP
SEIcarP is an R package (R Core Team 2021) implementing the
Spatially Explicit Invasive Carp (SEICarP; sometimes stylize as SEIcarP)
population model for the Illinois River.
This repository contains the SEIcarP model plus two additional
packages required for the main model package to run.
These are the SEIcarP Bighead Carp (BH) data (SEIcarPdataBHCP) and
the SEIcarP Silver Carp (SV) data (SEIcarPd
CoSMoS-COAST: The Coastal, One-line, Assimilated, Simulation Tool of the Coastal Storm Modeling System
A software release of CoSMoS-COAST: The Coastal, One-line, Assimilated, Simulation Tool of the Coastal Storm Modeling System. The software (coded in Matlab) encapsulates a long-term shoreline change model that combines longshore and cross-shore transport and assimilates historical shoreline observations.
The effects of wastewater reuse on smallmouth bass (Micropterus dolomieu) relative abundance in the Shenandoah River Watershed, USA
R code to evaluate the effects of wastewater reuse on smallmouth bass (Micropterus dolomieu) relative abundance in the Shenandoah River Watershed, USA
A hydrological modeling framework for lake water level drawdown management
This model was written in python3 which can simulate water level fluctuations under different drawdown operation rules. We submitted the manuscript about this model to the Journal of Environmental Management. The model file was saved in directory “models/WDLake”, and you can reproduce the results by running the jupyter notebooks in “notebooks/”.
Code for Multiple Population Viability Analysis of egg mass time series from the Foothill Yellow-legged Frogs (Rana boylii) in California
Code to fit a Multiple Population Viability Analysis (MPVA) to time series of Foothill yellow-legged frog (Rana boylii) egg mass counts.

Adaptive Topobathymetric Fusion Software Version 1.0
Software release for a topobathymetric DEM fusion approach. The operation, theory, and processes used in this software release can be used to fuse two topobathymetric digital elevation models (DEMs), creating seamless transitions around the two datasets' seamlines. This software heavily utilizes the arcpy python module, installation of ArcGIS Pro and a valid spatial analyst license is required.
Example application of MetaIPM to the Illinois River
This repository contains an example application of the `Meta-IPM` Python package (https://doi.org/10.5066/P9PW673G).
The specific application focuses on the Illinois River using existing public data.
Indiana mussel metabolomics data analysis
This repository contains code to cluster a sample of Mussels based up their metabolic levels via Non-Metric Multidimensional Scaling (NMDS) and distance based-Redundancy Analysis (db-RDA). Mussel sample is broken down and examined by catch location, sex, and species. The code for this project assumes the reader is familiar with R and clustering techniques.
Calculations of BioLake climate data
Climate data allow people to examine species distributions and possible distributions.
This script takes ERA5-Land climate estimates (https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5) for precipitation and lake temperature and processes them to create summary climate layers for use with biological organisms in lakes. This code could be modified to use a different subset of year
Interpolating missing water quality data
This repository contains analysis codes to interpolate missing data from the Upper Mississippi River LTRM dataset.
