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...

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...

Spatial distribution and relative biomass of bigheaded carps in Lake Balaton, Hungary estimated from an environmental DNA survey Spatial distribution and relative biomass of bigheaded carps in Lake Balaton, Hungary estimated from an environmental DNA survey
Silver carp (Hypophthalmichthys nobilis), bighead carp (H. molitrix) and their hybrids, collectively known as bigheaded carps, have been introduced to Lake Balaton, Hungary. The current stock sizes are difficult to assess. We investigated environmental DNA (eDNA) techniques targeted for bigheaded carps, assessed the spatial distribution of eDNA in Lake Balaton, compared eDNA...

Satellite assessment of winter cover crop and conservation tillage outcomes to support adaptive management in working landscapes Satellite assessment of winter cover crop and conservation tillage outcomes to support adaptive management in working landscapes
The use of winter cover crops and conservation tillage are agricultural practices promoted to reduce nutrient and sediment loss from cropland, improve soil health, increase infiltration, and support farm nutrient cycling and ecosystem services. However, environmental performance of these practices is variable in the working farm landscape. The Lower Chesapeake Bay research project within...

Do bighorn sheep use desert tortoise burrow spoil piles as mineral licks in southern California? Do bighorn sheep use desert tortoise burrow spoil piles as mineral licks in southern California?
In a previous study, bighorn sheep (Ovis canadensis) were periodically photographed by trail cameras when they visited desert tortoise (Gopherus agassizii) burrows in the San Bernardino Mountains near Palm Springs, California, USA. The authors suggested that bighorn sheep may utilize the excavated spoil material from burrows as a mineral lick. To test that supposition, we collected soil...

Tracing invasion routes of Cuban treefrogs into Louisiana using mitochondrial DNA Tracing invasion routes of Cuban treefrogs into Louisiana using mitochondrial DNA
Understanding the origin and spread of invasive species is critical for predicting when and where new introductions will establish, and impact native species. However, due to the complexity of contributing factors such as multiple introductions, dispersal method, genetic admixture in founding populations, and variable propagule pressure, genetic patterns observed in invasive species may...

Variation in detection distance of Eastern Black Rail (Laterallus jamaicensis jamaicensis) vocalizations by autonomous recording units Variation in detection distance of Eastern Black Rail (Laterallus jamaicensis jamaicensis) vocalizations by autonomous recording units
Autonomous recording units (ARUs) are an emerging technology that allows for passive monitoring of soniferous animals and soundscapes. Over the past decade, ARUs have become a popular tool for monitoring birds for their potential to reduce the labor and costs of traditional in-person sampling procedures. However, uncertainty surrounding factors affecting detection of avian taxa using...

Initial responses of songbird communities to forest reclamation on legacy surface mines Initial responses of songbird communities to forest reclamation on legacy surface mines
Surface coal mining and subsequent reclamation efforts in the Appalachian Mountains, USA, transform the ecological characteristics of natural landscapes. The Forestry Reclamation Approach (FRA) is a mine reclamation method that emphasizes best management practices in forestry. FRA practices have demonstrated success in establishing native forests and accelerating natural succession on...

Grass carp (Ctenopharyngodon idella) movement states and backwater use can inform removal efforts Grass carp (Ctenopharyngodon idella) movement states and backwater use can inform removal efforts
Expansion of grass carp (Ctenopharyngodon idella) within the Laurentian Great Lakes poses significant ecological and economic risks. Suppression efforts to remove grass carp have increased to curtail population growth, but capture efficiency remains low. One management challenge is the lack of understanding how this invasive species is using its novel habitats in the Great Lakes. This...
