Summary of 2019 Environmental Toxicology and Chemistry articles: Data and Code Summary of 2019 Environmental Toxicology and Chemistry articles: Data and Code
Statistical inferences play a critical role in ecotoxicology. Historically, Null Hypothesis Significance Testing (NHST) has been the dominant method for inference in ecotoxicology. As a brief and informal definition of the NHST approach, researchers compare (or test) an experimental treatment or observation against a hypothesis of no relationship or effect (the null hypothesis) using the...
Anchored hybrid enrichment in Potamilus mussels Anchored hybrid enrichment in Potamilus mussels
Freshwater mussels are a species-rich group with biodiversity patterns shaped by life history strategies that include an obligate parasitic larval stage. Anchored hybrid enrichment (AHE) and ancestral character reconstruction (ACR) revealed convergence of life history strategies involving larval morphologies that reduce size to increase fecundity and require growth during encapsulation...
Wolf Hematology in the Superior National Forest, 1989-1993 Wolf Hematology in the Superior National Forest, 1989-1993
Hematology and body mass were studied in nine female and five male free-ranging wolves in the Superior National Forest handled 4-17 times during 1989-1993. The dataset includes the following data for each wolf studied: wolf identifier, dates caught, sex, age, body mass in kg, adjusted body mass in kg, and values of hemoglobin (Hb), red blood cells (RBC), mean corpuscular hemoglobin (MCH)
ORByT - Optical River Bathymetry Toolkit ORByT - Optical River Bathymetry Toolkit
The Optical River Bathymetry Toolkit, ORByT, is an application to facilitate mapping water depth in river channels from passive optical image data. ORByT provides an integrated workflow for image processing, depth retrieval, and export of results.
Nitrogen biogeochemistry in a boreal headwater stream network in Interior Alaska, 2008 to 2011 Nitrogen biogeochemistry in a boreal headwater stream network in Interior Alaska, 2008 to 2011
High latitude, boreal watersheds are nitrogen-limited ecosystems that export large amounts of organic carbon. Key controls on carbon cycling in these environments are the biogeochemical processes affecting the nitrogen cycle. This data release presents results of a 3-year field study from 2008-2011 to document the relation between seasonal and transport-associated changes in carbon and...
Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2018 Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2018
A potentiometric-surface map for spring 2018 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some...
