Fully stochasticized age-structured population-bioenergetics model ensemble for application to communities Fully stochasticized age-structured population-bioenergetics model ensemble for application to communities
his is an R program for simulating multiple fish populations using species-specific projection matrices, interaction matrices, and bioenergetics submodels with hierarchical stochasticity. This program was designed to model the pallid sturgeon (Scaphirhynchus albus) and associated fish species in the Lower Missouri River (Wildhaber et al. 2024), but it should be sufficiently general to...
pfdf 3.0.0 pfdf 3.0.0
This release adds the `data` package, which provides routines to download commonly used datasets from the internet. The release also provides pfdf tutorials as Jupyter Notebooks, improves array broadcasting in the `gartner2014` and `staley2017` modules, and introduces the `RasterMetadata` class (which manages raster metadata without loading data arrays to memory). Documentation: https:/...
DynRat DynRat
DynRat was developed by the USGS to develop dynamic rating models using a method called DYNPOUND, which accommodates compound and compact channel geometry to model hysteresis. The latest release can be downloaded from the releases section in the repository. Additions, bug fixes, changes, and links to releases can be viewed in the [/dynamic-rating/dynrat/-/blob/master/userguide/docs...
HIRBERT HIRBERT
This standalone software application provides a means of inferring water depth from passive optical remotely sensed data via a machine learning-based workflow: Hyperspectral Imaging of River Bathymetry using an Ensemble of Regression Trees, or HIRBERT for short. This approach could provide accurate depth estimates in clear-flowing, relatively shallow streams but is less likely to yield...
Grfin Tools—Software Package and Runtime Documentation for Users Grfin Tools—Software Package and Runtime Documentation for Users
Grfin Tools (an acronym of Growth + flow + inundation) is a set of software tools for portraying areas potentially impacted by runout from landslides or inundation from geophysical mass-flows (such as debris flows) with or without growth as they travel. Grfin Tools allows users to assess the effects of a wide range of factors that can influence mobility. The software also enables runout
Contact rates for identifying interactions of white-tailed deer in a chronic wasting disease management area Contact rates for identifying interactions of white-tailed deer in a chronic wasting disease management area
Examinations of contact rates among white-tailed deer (Odocoileus virginianus; hereafter, deer) are important to applied management objectives given their societal value and disease transmission potential. This R script was used to curate the original GPS collar and capture data from Pennsylvania DMA2 in preparation for contact rates analysis.
