spatial_nsm: Spatial estimates of soil-climate properties using a modified Newhall simulation model spatial_nsm: Spatial estimates of soil-climate properties using a modified Newhall simulation model
We developed a software framework to estimate high-resolution spatiotemporal soil moisture (monthly, annual, and seasonal) and temperature-moisture regimes. Our approach builds on the Newhall simulation model, allowing for the substitution of data and parameters, such as climate, snowmelt, soil properties, alternative potential evapotranspiration equations, and air-soil temperature...
Spatial modeling of two mosquito vectors of West Nile virus using integrated nested Laplace approximation Spatial modeling of two mosquito vectors of West Nile virus using integrated nested Laplace approximation
This software involves R script to fit models of abundance of mosquito vectors (' Script_for_ECS22-0193_9_13_2215.R') to landscape and environmental covariates using INLA and SPDE. The dataset used for this analysis were originally provided by the Pennsylvania Department of Environmental Protection (DEP) with a confidentiality agreement. The majority of the data used in this study...
StreamStats Channel Width Weighting Services StreamStats Channel Width Weighting Services
This software release contains Python functions for weighting multiple non-independent estimates of a variable. Weighting is determined by the standard error of prediction of each estimate and the correlation between the estimation methods. The methodology for weighting estimates from either two or three different methods is described in Chase and others (2020). A function is also...
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...
