Potential thiamine deficiency of phytoplankton across a productivity gradient and seasons in Ohio lakes Potential thiamine deficiency of phytoplankton across a productivity gradient and seasons in Ohio lakes
Although nitrogen and phosphorus deficiency of algal blooms have been the focus of substantial attention, organic nutrients can limit algal growth in aquatic systems. Growing evidence indicates thiamine (vitamin B1) can influence the community of primary producers in marine systems, but comparatively little is known about the effect of thiamine on freshwater algal productivity.We...

Causal networks to inform decisions for ecological restoration Causal networks to inform decisions for ecological restoration
The release of contaminants into the environment can occur from anthropogenic activities, such as oil extraction and transportation, mining, and industrial processes. Remediation associated with reducing contaminant concentrations, and restoration that improves animals and supporting habitat, are often needed to restore ecosystems to their pre-release, baseline condition. We demonstrated...

Assessing the topographic distribution of legacy soil phosphorus in agricultural fields of the Delmarva Peninsula, Mid-Atlantic Coastal Plain, USA Assessing the topographic distribution of legacy soil phosphorus in agricultural fields of the Delmarva Peninsula, Mid-Atlantic Coastal Plain, USA
Phosphorus (P) management remains a challenge in agricultural watersheds. The Choptank River Conservation Effects Assessment Project watershed, located in Maryland and Delaware and draining to the Chesapeake Bay, contains legacy soil P from historical dairy and poultry manure applications. These practices elevated soil P beyond crop needs, contributing to persistent P export to aquatic...

Estimating flood discharges at selected annual exceedance probabilities for unregulated, rural streams in Vermont, 2023 Estimating flood discharges at selected annual exceedance probabilities for unregulated, rural streams in Vermont, 2023
This report provides estimates of flood discharge at selected annual exceedance probabilities (AEPs) for streamgages in and adjacent to Vermont and equations for estimating flood discharges at AEPs of 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent (recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-years, respectively) for ungaged, unregulated, rural streams in Vermont with...

Tetrabromobisphenol S (TBBPS) causes non-negligible and multigenerational reproductive toxicity in zebrafish Tetrabromobisphenol S (TBBPS) causes non-negligible and multigenerational reproductive toxicity in zebrafish
Tetrabromobisphenol S (TBBPS) is one of the most extensively used brominated flame retardants detected in the environment. Despite its widespread presence, the effects of persistent environmental exposure to TBBPS on the reproductive system remain unclear, raising significant health concerns. Here, using the zebrafish (Danio rerio) model, we identified significant intergenerational...

Predictors of mercury and pesticide fluxes by emerging adult aquatic insects from prairie pothole wetlands Predictors of mercury and pesticide fluxes by emerging adult aquatic insects from prairie pothole wetlands
Aquatic and terrestrial food webs are linked by movements of aquatic insects during their development from larvae to adults. Contaminants can affect these linkages by reducing insect survival and increasing tissue contaminant concentrations through adult metamorphosis, thus changing contaminant flux from water to land. Most anthropogenically influenced freshwater ecosystems are exposed...

How high? Identifying elevation thresholds to guide coastal marsh restoration How high? Identifying elevation thresholds to guide coastal marsh restoration
Introduction Coastal marshes are highly valuable ecosystems facing threats from rising sea levels and intensifying storm events. To elevate marsh surfaces and prevent loss of ecosystem services, the beneficial use of dredged material (BUDM) is increasingly being implemented across the United States. Objectives The objective of this study was to aid decision-makers and restoration...

Predator effects on the survival of juvenile invasive carp in simulated backwater habitats Predator effects on the survival of juvenile invasive carp in simulated backwater habitats
Numerous control methods are in use and under development to manage invasive carps in the United States. Commercial harvest, electric deterrents, and chemical toxicants, among other methods, are most efficient at targeting larger individuals. Research on methods to control recruitment of juvenile invasive carps has been limited. Our primary objective was to assess the vulnerability of...

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species...

Modeling the influence of upper and lower shoreface dynamics on barrier island evolution Modeling the influence of upper and lower shoreface dynamics on barrier island evolution
Barrier island resilience to climate impacts depends on sediment redistribution between the subaqueous shoreface and subaerial barrier during sea-level rise and storms. However, autogenic interactions between the upper and lower shoreface and their influence on the subaerial barrier are poorly characterized. Here, we explore the influences of various shoreface components on barrier...

Understanding abundances and behaviors of shorebirds in coastal Louisiana Understanding abundances and behaviors of shorebirds in coastal Louisiana
Barrier islands provide resources and ecological services that are integral to economic and environmental interests, such as protection of coastal infrastructure and provision of wildlife habitat. Over time, barrier islands may become eroded and experience land loss, which can require management actions to restore island integrity. Barrier island restoration can create or modify habitats...

Variation in soil organic carbon across a latitudinal chronosequence of mangrove poleward expansion Variation in soil organic carbon across a latitudinal chronosequence of mangrove poleward expansion
The critical carbon sink provided by coastal wetlands, known as blue carbon, can be affected by multiple aspects of climate change. One important example is warming-induced mangrove poleward expansion, which is shifting dominant plant cover across tropical–temperate transitional zones and altering ecosystem structure and function. We examined how mangrove expansion affects soil organic...
