African fish mercury burden and isotopic composition from archived museum specimens African fish mercury burden and isotopic composition from archived museum specimens

Fish collected for taxonomic and systematic purposes are often preserved and then archived in museum collections. Preserved fish are commonly first fixed in a formalin solution and then transferred to ethanol for long-term storage. The wet preservation method can potentially introduce mercury (Hg) contamination or unintentionally extract Hg from tissue. An experiment was designed to test...

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.

Supplemental data and documentation of VS2DH seepage models: Incorporating temperature into seepage loss estimates for a large irrigation canal Supplemental data and documentation of VS2DH seepage models: Incorporating temperature into seepage loss estimates for a large irrigation canal

This USGS data release presents tabular data and a model archive used to estimate seepage rates at 19 locations on the Truckee Canal for the 2018 and 2019 irrigation seasons. This supplemental data release consists of two child items: (1) Model archive of two-dimensional variably saturated heat and flow models (VS2DH) used to examine seepage rates in the Truckee Canal at 19 transect...

Potomac River ADCP Bathymetric Survey, October 4-7, 2021 Potomac River ADCP Bathymetric Survey, October 4-7, 2021

Bathymetric LiDAR technology was used to collect riverbed elevation data along the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area during October 4-7, 2021. The study area consisted of four verification reaches on the Potomac River including: 1) Williamsport accessed through the...

Expert assessments of hypotheses concerning the etiological agent(s) of Stony Coral Tissue Loss Disease collected during a rapid prototyping project Expert assessments of hypotheses concerning the etiological agent(s) of Stony Coral Tissue Loss Disease collected during a rapid prototyping project

This dataset is from expert elicitation of a panel of 15 experts with knowledge of stony coral tissue loss disease (SCTLD) and its impacts on coral reefs. We gathered this group of 15 participants with diverse expertise who had previously studied SCTLD including at universities and various government agencies as microbiologists, pathologists, disease ecologists, population ecologists...

Hawaiian hoary bat population genetics 1988 to 2020 Hawaiian hoary bat population genetics 1988 to 2020

Genetic diversity levels, effective population size estimates, and population structure of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) were examined across the islands of Hawai‘i, Maui, O‘ahu, and Kaua‘i using eighteen nuclear microsatellite loci and one mitochondrial gene from 339 individuals collected between 1988 and 2020. The study extracted...
