The Gage Statistic (GageStats) Services were developed to provide gage characteristics and streamflow statistics to support the StreamStats application via RESTful principles. The StreamStats application uses GageStats Services to display the gages and related gage pages. These services provide U.S. Geological Survey developed and published gage characteristics such as drainage area or mean basin

Tools and metadata for the USGS Model Catalog.

The U.S. Geological Survey (USGS) developed an R package called dataRetrieval to help simplify the process of discovering and retrieving water quality sample data, streamflow, groundwater, and other data available from Federal hydrologic web services such as National Water Information Systems (NWIS), the EPA Water Quality Exchange (WQX) System, and the National Hydrologic Dataset via the Hydro-Ne

Quantitative fatty acid signature analysis (QFASA; Iverson et al. 2004) has become a common method of estimating diet composition, especially for marine mammals, but the performance of the method has received limited investigation. Bromaghin et al. (In press) used computer simulation to compare the bias of several QFASA estimators and developed recommendations regarding estimator selection. Simula

This software release contains one R script file that allows the user to download data and reproduce all of the figures and analyses associated with DiRenzo et al. In the R script, we provide a guide to understanding and validating complex models using data simulations. In an effort to facilitate the implementation of these methods, we provide a running example throughout DiRenzo et al. 2022 with

We developed a method to construct hierarchically nested and biologically relevant groupings of similar habitats associated with field surveys while considering structure/connectedness (movements between habitats). This approach can support mobile species using high fidelity sites where monitoring during surveys occurs, such as birthing grounds, breeding grounds, or stopovers/seasonal habitats for

The distance within which populations respond to features in a landscape (scale of effect) can indicate how disturbance and management may affect wildlife. Using annual counts of male greater sage-grouse (Centrocercus urophasianus) attending 584 leks in southwest Wyoming (2003-2019) and estimates of sagebrush (Artemisia spp.) cover from a remote sensing product (Rigge et al., 2021; Monroe et al.,

This version of ModelMuse fixes a serious bug in ModelMuse version 5.1.

The ReplicateChar package in R language provides functions for visualization and analysis of replicated charcoal counts within a discreet sedimentary horizon. The package consists of 1000+ lines of code and requires Windows OS for full functionality. It also integrates and automates the CharAnalysis.exe software (Higuera et.al) and allows for more efficient run times of high volumes of original an

ModelMuse version 5.1 updates version 5.0 by adding support for the groundwater transport process and time series files in MODFLOW 6.
