Linking dissolved organic matter composition to landscape properties in wetlands across the United States of America
Wetlands are integral to the global carbon cycle, serving as both a source and a sink for organic carbon. Their potential for carbon storage will likely change in the coming decades in response to higher temperatures and variable precipitation patterns. We characterized the dissolved organic carbon (DOC) and dissolved organic matter (DOM) composition from 12 different wetland sites across the USA
Lead poisoning of raptors: State of the science and cross-discipline mitigation options for a global problem
Lead poisoning is an important global conservation problem for many species of wildlife, especially raptors. Despite the increasing number of individual studies and regional reviews of lead poisoning of raptors, it has been over a decade since this information has been compiled into a comprehensive global review. Here, we summarize the state of knowledge of lead poisoning of raptors, we review dev
Abundance of Long-billed Curlews on military lands in the Columbia Basin
Long-billed Curlews (Numenius americanus) are declining throughout North America, and the loss of grassland breeding habitat is one of the primary threats to the species. Intermountain West, in particular, has been identified as the most important region in North America for breeding curlews. Nevertheless, the density and abundance of Long-billed Curlews in this region is not well understood. Land

Expanding Distribution of Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in 34 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 34 states and four provinces and in captive cervid facilities in 19 states and three provinces.
2022 Year in Review
This has been another outstanding year for the CRU Program, and I am pleased to provide you with our 2022 Year in Review report. Highlights of this past year include the creation of our 42nd unit at Michigan State University and the completion of hiring activities for 37 new unit scientists in 31 States. In this report, you will learn more about the spectacular accomplishments of our students...
Human-Related Compounds in Water Sources in the Grand Canyon Help Identify Water Flow Pathways and Highlight Potential Water Quality Changes
U.S. Geological Survey (USGS) scientists investigated the movement of human-generated chemicals, such as pharmaceuticals and per- and polyfluorinated substances (PFAS), in groundwater along the South Rim of the Grand Canyon. This research led to a better understanding of the movement of wastewater into groundwater, of complex underground flow patterns, and of chemicals present in springs near...
