Predicting climate change impacts on poikilotherms Predicting climate change impacts on poikilotherms
This software involves files to fit the physiologically-guided abundance (PGA) model ('fish_predictions_pga.R'), a naive model ('fish_predictions_naive.R'), and a PGA model using simulated data ('PGA_sim.R'). Each R file calls as associated .stan file that contains the model code that is executed by stan when running the R code ('fish_prediction.stan', 'fish_prediction_naive.stan', and...
High-throughput calculations of climatch scores High-throughput calculations of climatch scores
Matching climate envelopes allows people to examine how potential invasive species may match habitats. This repository contains code for using the climatchR package for high-throughput calculations of climatch scores for species using GBIF data. Climatch is based upon the climatch algorithm as implemented through the climatchR package.
Analysis code for Quantitative method development to determine feed consumption using a dye Analysis code for Quantitative method development to determine feed consumption using a dye
This repository contains code for the analysis of Wamboldt JJ, Nelson JE, Thomas LM, Steiner JN, Hebert JL, Erickson RA, Putnam JG. Quantitative method development to determine feed consumption using a dye. North American Journal of Aquaculture The purpose of the repository is to document what analysis was run for publication and is intended for an archive rather than a production or...
AMMonitor AMMonitor
AMMonitor is an open source R package dedicated to collecting, storing, and analyzing AMU information in a way that 1) is cost-effective, 2) can efficiently process and store information, and 3) can take advantage of the vast and growing community of R analytics.
LinkedBNs_4Habitat - Matlab files to link Bayesian networks to generate habitat predictions LinkedBNs_4Habitat - Matlab files to link Bayesian networks to generate habitat predictions
Matlab m-files that were used to generate performance tests and hindcasts for geomorphologic characteristics and piping plover habitat probabilities for Fire Island New York
NWTOPT NWTOPT
Hyperparameter optimization approaches were applied to improve performance and accuracy of groundwater flow models. Freely available new software, NWTOPT, is described that uses Tree of Parzen Estimators (TPE) and Random Search optimization algorithms to optimize MODFLOW-NWT’s solver settings. We ran 3500 trials on a steady-state and transient model. To quantify the performance of...
