Code for Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River Code for Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River
The program computes eight metrics reflective of lake and stream connectivity including duration, timing, recurrence, continuance, disconnectedness, dry season, wet season, and seasonality.
Code for Idiosyncratic spatial scaling of biodiversity–disease relationships Code for Idiosyncratic spatial scaling of biodiversity–disease relationships
This repository contains data and code supporting the Gilbert et. al manuscript entitled, "Idiosyncratic spatial scaling of biodiversity–disease relationships". The objective of the paper is to evaluate how estimated relationships between Lyme disease risk and host biodiversity change when host biodiversity is quantified at different spatial scales. Data come from the National Ecological...
Precipitation Runoff Modeling System (PRMS) Precipitation Runoff Modeling System (PRMS)
The Precipitation-Runoff Modeling System is a deterministic, distributed-parameter, physical process based modeling system developed to evaluate the response of various combinations of climate and land use on streamflow and general watershed hydrology.
Pan-Amphibia Bd distribution: software release Pan-Amphibia Bd distribution: software release
This software release contains the code necessary to reconstruct analyses, tables, and figures presented in "Pan-Amphibia distribution of the fungal parasite Batrachochytrium dendrobatidis varies with species and temperature." These analyses compile temperature and precipitation data with Bd data for a cross-sectional amphibian swabbing survey performed 2014-2017, perform spatial data...
Analysis of monthly water supply for the United States for water years 2010-2020 using modeled states and fluxes Analysis of monthly water supply for the United States for water years 2010-2020 using modeled states and fluxes
This pipeline analyzes estimates of streamflow, evapotranspiration, soil moisture, and snow water equivalent among other hydrologic states and fluxes from two national hydrologic models: the National Hydrologic Model application of the Precipitation-Runoff Modeling System (NHM-PRMS) and the Weather Research and Forecasting hydrologic modeling system (WRF-Hydro). Both of these models are...
Visualizations of water quality across the conterminous United States using SPARROW 2012 simulated nutrient load estimates Visualizations of water quality across the conterminous United States using SPARROW 2012 simulated nutrient load estimates
This pipeline uses the data from the 2012 regional Sparrow models (see **Input datasets** below) to produce four types of outputs: 1. Maps of SPARROW-estimated total nitrogen, total phosphorus, and total suspended-sediment yields and concentrations across the conterminous United States (CONUS); 2. Bar plots showing the amount of total nitrogen, total phosphorus, and suspended sediment...
Climate-driven declines in fish abundance workflow and analysis Climate-driven declines in fish abundance workflow and analysis
This repository provides the necessary R and stan scripts to fit a joint species, spatially dependent physiologically guided abundance (jsPGA) model (Custer et al. 2024) to fishes from over 11,000 Midwestern US lakes in an effort to predict the effects of climate change on their abundance, distributions, and extirpation probabilities.
Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America
The Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America is an effort to map the breeding locations of coastal breeding waterbirds in the northern Gulf of America from 2010-2022. The Atlas was developed to provide stakeholders in the region with a means to readily access the location and status (both recent and current) of sites used for breeding activities by a wide...
Code for Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks Code for Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks
The Missouri Stream Conservation and Connectivity Prioritization Tool can be used to identify the number and nature of barriers to fish movement between stream reaches. This data can be used to target stream reaches for protection, conservation, and reestablishing connectivity within and between existing conservation networks. The tool allows users to select a subset of stream reaches...
Socioeconomic effects of bison and elk management alternatives on National Elk Refuge Socioeconomic effects of bison and elk management alternatives on National Elk Refuge
The purpose of this software is to develop predictions about future changes in the social and economic benefits provided by bison and elk and their management on the National Elk Refuge. The effects are estimated as a function of changing wildlife populations under different management alternatives. For additional detail on the methodology and case study, please refer to: McEachran, M.C...
