Reduction of large vessel traffic improves water quality and alters fish habitat-use throughout a large river
Rivers are increasingly used as superhighways for the continental-scale transportation of freight goods, but the ecological impact of large vessel traffic on river ecosystems is difficult to study. Recently, the temporary maintenance closure of lock and dam systems on the Illinois Waterway (USA) brought commercial vessel traffic to a halt along the river's length, offering a rare opportunity to st
Side-scan sonar as a tool for measuring fish populations: Current state of the science and future directions
Side-scan sonar (SSS) is a powerful tool that can be used to address many key questions in fisheries science. In principle, SSS uses dual transducers to transmit a narrow-beam, wide-angle acoustic signal as the survey vessel transits an area. The intensity of reflected sound is recorded to generate an image mosaic comprised of benthic substrates and targets in the water column, including organisms
A reproducible manuscript workflow with a Quarto template
Scientists and resource managers increasingly use Markdown-based tools to create reproducible reports and manuscripts. These workflows allow people to use standardized methods that are more reproducible, efficient, and transparent than other standard office tools. We present a Quarto template and demonstrate how this template may be used for a journal, the Journal of Fish and Wildlife Management,

Estimating Methylmercury Injury to Birds—“The Bird Mercury Tool”
U.S. Geological Survey (USGS) scientists have developed a tool that can be used by practitioners to help interpret injury to birds caused by methylmercury contamination. This tool was developed from a comprehensive review of 168 studies and summarizing data on the effects of methylmercury on birds.
U.S. Geological Survey Science Opportunities Related to the Nationally Relevant Study of Harmful Algal Blooms and Algal Toxins
In 2024, the U.S. Geological Survey (USGS) released a strategic vision document identifying harmful algal bloom (HAB) and algal toxin science gaps, while prioritizing research relevant to the mission, expertise, and capabilities of the USGS. The intention is for USGS and stakeholders to use this document as a starting point for planning, prioritizing, and designing future HAB and algal toxin...
Seabirds and Forage Fish Ecology
Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species; from loons and seaducks that nest inland, to petrels and puffins that breed on islands off shore. All these birds depend on the sea to provide a wide variety of food types— from clams, crabs and urchins nearshore— to krill, forage fish, and squid offshore. The...
