Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

White-tailed deer and sharp-tailed grouse data used in constrained generalized additive models to enhance survival analyses and incorporate ecological theory White-tailed deer and sharp-tailed grouse data used in constrained generalized additive models to enhance survival analyses and incorporate ecological theory
Grouse: These data on sharp-tailed grouse survival times are provided for individuals wanting to run an age-period survival analysis. Entry and exit times are expressed in integer days from the start of the study. Entry age and exit age expressed in integer days are also included. Data are structured to implement survival analysis. White-tailed Deer: These data on white-tailed deer...
Code for Assimilating ecological theory with empiricism: Using constrained generalized additive models to enhance survival analyses Code for Assimilating ecological theory with empiricism: Using constrained generalized additive models to enhance survival analyses
Code will be submitted to the Dryad repository upon acceptance of the manuscript. These R code are used for simulations and case studies. Simulations include data for generating age-period survival data. We have provided code for each of the 10 models that were fit using NIMBLE, where each model has four R scripts including: 1) A script to execute and run all the additional R scripts for...
Code for Rapid prototyping for quantifying belief weights of competing hypotheses about emergent diseases Code for Rapid prototyping for quantifying belief weights of competing hypotheses about emergent diseases
Code submitted to Journal of Environmental Management and ScienceBase for running Bayesian hierarchical models on a dataset that was collected using expert elicitation of a panel of 15 experts on the etiology of stony coral tissue loss disease and its impacts on coral reefs. The code is for a rapid prototyping method for quantifying belief weights for competing hypotheses about the...
Great Lakes Restoration Initiative: Nutrient cycling in riverbed sediment in the Maumee River Basin, 2019 and 2021 Data (ver. 2.0, March 2024) Great Lakes Restoration Initiative: Nutrient cycling in riverbed sediment in the Maumee River Basin, 2019 and 2021 Data (ver. 2.0, March 2024)
The Maumee River transports huge loads of nitrogen (N) and phosphorus (P) to Lake Erie. The increased concentrations of N and P are causing eutrophication of the lake, creating hypoxic zones, and contributing to phytoplankton blooms. It is hypothesized that the P loads are a major contributor to harmful algal blooms that occur in the western basin of Lake Erie, particularly in summer...
The North American Breeding Bird Survey, Analysis Results 1966 - 2021 The North American Breeding Bird Survey, Analysis Results 1966 - 2021
This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross
Isotope data from Shimada 2018 research expedition Isotope data from Shimada 2018 research expedition
Stable isotope data of fauna, particulate organic matter, and rocks collected during the 2018 research cruise aboard the NOAA Ship Bell M. Shimada that examined benthic communities off the western U.S. coast.
