Freshwater fish biodiversity and distribution in the Northeastern United States Freshwater fish biodiversity and distribution in the Northeastern United States
This software contains 3 separate R Markdown files and 1 R script file that comprise an analysis to 1. collate freshwater fish survey data from within the northeastern United States, 2. develop separate models to predict the probability of occurrence and the proportional abundance of 53 freshwater fish species, and 3. combine model results by fish species traits and habitat...
R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations
Brook trout are a recreationally important fish species that need cold water for survival. The objective of this study was to quantify within- and among-population variability in HSP47 and CIRBP expression in four wild populations of brook trout (Salvelinus fontinalis) to quantify seasonal changes in gene expression. The code release contains a R script for the analysis of brook trout...

Aftershock Forecaster is a GUI program that runs on the desktop and is used to compute ETAS-based aftershock forecasts.
R script to simulate point-count data and estimate population trend under various scenarios of changing phenology R script to simulate point-count data and estimate population trend under various scenarios of changing phenology
The script in this code repository simulates point-count data under an example scenario, sets up model input, and runs an N-mixture model with two components of detection (availability and perceptibility) to estimate the population trend. This simulation and analysis were developed to evaluate the consequences of changing spring phenology for estimating population trend of breeding bird
Code to estimate effects of rice growing on growth and survival of giant gartersnakes, Thamnophis gigas Code to estimate effects of rice growing on growth and survival of giant gartersnakes, Thamnophis gigas
