Tidal wetland soil carbon accumulation rates for coastal California Tidal wetland soil carbon accumulation rates for coastal California
Carbon stock and carbon accumulation rate data are vital to multiple aspects of tidal wetland conservation and restoration policy. In California, USA tidal soil data are rare outside of the San Francisco Bay and Sacramento Delta regions, despite the differing conditions experienced by the outer coastline. Here we provide carbon stocks and decadal-to-centennial-scale carbon accumulation...

Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska) Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska)
Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide-generated seismic and infrasound (low-frequency atmospheric sound) waves can be remotely detected in near real-time. This information can significantly...

Genomic selection for low salinity tolerance in the eastern oyster Crassostrea virginica in Louisiana and Chesapeake Bay populations Genomic selection for low salinity tolerance in the eastern oyster Crassostrea virginica in Louisiana and Chesapeake Bay populations
The use of genomic selection (GS) to improve traits of interest in aquaculture species is growing with the availability of genomic resources for those species. The eastern oyster, Crassostrea virginica, is a major aquaculture product and keystone species along the U.S. mid-Atlantic and Gulf coasts. Populations and production of C. virginica are threatened by several environmental...

Development of a SWAT+ model to improve conservation practice efficacy for protecting stream health in karst pasturelands Development of a SWAT+ model to improve conservation practice efficacy for protecting stream health in karst pasturelands
Placing appropriate conservation practices in critical source areas of pollutants can benefit stream health in karst environments susceptible to agricultural pollution. Watershed models, such as the Soil and Water Assessment Tool+ (SWAT+), can optimize both practice selection and placement across the landscape, but to our knowledge no studies have tested this model in karst pasturelands...

Population trends of dabbling ducks wintering in the alluvial valleys of Arkansas and Mississippi Population trends of dabbling ducks wintering in the alluvial valleys of Arkansas and Mississippi
Population abundances, distributions, and compositions across a diversity of taxa are changing, partly as a consequence of human-induced global modifications. Although linking population fluctuations to anthropogenic-induced alterations can be challenging, it is increasingly clear that long-term monitoring is critical to understanding changing populations. For waterfowl, concerns over...

A synthesis of plant mass mortality events in coastal ecosystems A synthesis of plant mass mortality events in coastal ecosystems
Around the world, mass mortality events are disrupting the ecological and economic stability of shorelines. To better understand mechanisms of mass mortality in coastal ecosystems, we provide a global synthesis of over 250 reports of plant mass mortality events in six coastal ecosystems: coastal freshwater forests, tidal freshwater marshes, salt marshes, mangrove forests, seagrass...

Decadal shifts in groundwater age detected by environmental tracers across California, USA Decadal shifts in groundwater age detected by environmental tracers across California, USA
Groundwater age offers important insight into recharge, storage, and contamination risk. Although models predict age changes can be driven by pumping and climate variability, direct observational evidence remains limited. Here, we analyzed paired environmental tracer suites (tritium, carbon-14, and tritiogenic helium-3) collected a decade apart from 268 wells across California to assess...

The collective application of shorebird tracking data to conservation The collective application of shorebird tracking data to conservation
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence-based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the...

Effects of mountain lion predation on reducing feral horse population growth rates: Panacea or pipedream? Effects of mountain lion predation on reducing feral horse population growth rates: Panacea or pipedream?
A goal of applied ecology is to evaluate how demographic rates contribute to population growth and how demography might be manipulated to achieve management objectives. In western North America, many feral horse (Equus caballus) populations occupying public lands are protected by federal law and managed for site-specific numerical targets. However, feral horses can exhibit population...

Sources and streambed storage of soft sediment and sediment-bound phosphorus in an agricultural Great Lakes tributary Sources and streambed storage of soft sediment and sediment-bound phosphorus in an agricultural Great Lakes tributary
The East River, an agricultural tributary to the Lower Fox River and Lake Michigan in Wisconsin, USA, has excessive phosphorus (P) and suspended-sediment loads that contribute to downstream eutrophication and habitat-related impairments. Spatial variations and connectivity in the sources and streambed storage of soft, fine-grained (silt and clay) sediment and related sediment-bound P...

Quantitative microbial risk assessment with microbial source tracking for enteric pathogens in southwest Wisconsin private wells Quantitative microbial risk assessment with microbial source tracking for enteric pathogens in southwest Wisconsin private wells
Private wells supply drinking water for many households, and their contamination by fecal microbes presents a risk of acute gastrointestinal illness (AGI). Risk is thought to vary by contaminating fecal source, but specific associations with fecal source are unknown for most private wells in the United States. This study characterizes AGI risk in Grant, Iowa, and Lafayette counties in...

Net CO2 emissions from dry inland waters persist in the presence of vegetation Net CO2 emissions from dry inland waters persist in the presence of vegetation
Many inland waters are shrinking due to shifts in climate and water diversion for human uses. As they dry out, their exposed sediments emit large amounts of carbon dioxide (CO2) to the atmosphere. However, current global estimates of CO2 emissions from dry inland waters are derived exclusively from bare sediment dark-chamber measurements that do not account for the colonization of...
