Tropical cyclones and the organization of mangrove forests: A review Tropical cyclones and the organization of mangrove forests: A review
Background Many mangrove ecosystems are periodically exposed to high velocity winds and surge from tropical cyclones and often recover with time and continue to provide numerous societal benefits in the wake of storm events. Scope This review focuses on the drivers and disturbance mechanisms (visible and functional) that tropical cyclones of various intensities have on mangrove ecosystem

Catalog of microscopic organisms of the Everglades, part 2—The desmids of the Arthur R. Marshall Loxahatchee National Wildlife Refuge Catalog of microscopic organisms of the Everglades, part 2—The desmids of the Arthur R. Marshall Loxahatchee National Wildlife Refuge
The Arthur R. Marshall Loxahatchee National Wildlife Refuge (refuge), Boynton Beach, Florida, contains approximately 147,000 acres southeast of Lake Okeechobee. Water quality in the interior portion of the refuge is strongly influenced by rainfall, resulting in slightly acidic waters with low dissolved ions. Desmids, a unique, ornate group of green algae loosely associated with submerged...

Changes in event‐based streamflow magnitude and timing after suburban development with infiltration‐based stormwater management Changes in event‐based streamflow magnitude and timing after suburban development with infiltration‐based stormwater management
Green stormwater infrastructure implementation in urban watersheds has outpaced our understanding of practice effectiveness on streamflow response to precipitation events. Long‐term monitoring of experimental urban watersheds in Clarksburg, Maryland, USA, provided an opportunity to examine changes in event‐based streamflow metrics in two treatment watersheds that transitioned from...

Predicting functional responses in agro-ecosystems from animal movement data to improve management of invasive pests Predicting functional responses in agro-ecosystems from animal movement data to improve management of invasive pests
Functional responses describe how changing resource availability affects consumer resource use, thus providing a mechanistic approach to prediction of the invasibility and potential damage of invasive alien species (IAS). However, functional responses can be context dependent, varying with resource characteristics and availability, consumer attributes, and environmental variables...

Influence of land use and hydrologic variability on seasonal dissolved organic carbon and nitrate export: Insights from a multi-year regional analysis for the northeastern USA Influence of land use and hydrologic variability on seasonal dissolved organic carbon and nitrate export: Insights from a multi-year regional analysis for the northeastern USA
Land use/land cover (LULC) change has significant impacts on nutrient loading to aquatic systems and has been linked to deteriorating water quality globally. While many relationships between LULC and nutrient loading have been identified, characterization of the interaction between LULC, climate (specifically variable hydrologic forcing) and solute export across seasonal and interannual...

Withdrawal and consumption of water by thermoelectric power plants in the United States, 2015 Withdrawal and consumption of water by thermoelectric power plants in the United States, 2015
The U.S. Geological Survey has developed models to estimate thermoelectric water use based on linked heat and water budgets. The models produced plant-level withdrawal and consumption estimates using consistent methods for 1,122 water-using, utility-scale thermoelectric power plants in the United States for 2015. Total estimated withdrawal for 2015 was about 103 billion gallons per day...

Groundwater/surface-water interactions along Ellerbe Creek in Durham, North Carolina, 2016–18 Groundwater/surface-water interactions along Ellerbe Creek in Durham, North Carolina, 2016–18
An assessment of groundwater/surface-water interactions along Ellerbe Creek, a major tributary to upper Falls Lake in Durham County, North Carolina, was conducted from July 2016 to March 2018 to determine if groundwater is a likely source of elevated nitrate input to the stream. Groundwater/surface-water interactions were characterized by synoptic streamflow measurements, groundwater...

Standardizing a non-lethal method for characterizing the reproductive status and larval development of freshwater mussels (Bivalvia: Unionoida) Standardizing a non-lethal method for characterizing the reproductive status and larval development of freshwater mussels (Bivalvia: Unionoida)
Actively monitoring the timing, development, and reproductive patterns of endangered species is critical when managing for population recovery. Freshwater mussels are among the most imperiled organisms in the world, but information about early larval (glochidial) development and brooding periods is still lacking for many species. Previous studies have focused on the complex life history...

Reaffirmed occurrence of two vulnerable caddisfly species of conservation concern Reaffirmed occurrence of two vulnerable caddisfly species of conservation concern
Maramec Spring is home to two Ozark endemic caddisfly Species of Conservation Concern (SOCC). The Missouri Glyphospsyche Caddisfly, Glyphospsyche missouri, (Critically Imperiled; State Rank-S1; Global Rank-G1) is known from Maramec Spring and the receiving spring branch and nowhere else in the world. Similarly, the Artesian Agapetus Caddisfly, Agapetus artesus, (Vulnerable; State Rank-S3...

Prediction and inference of flow-duration curves using multi-output neural networks Prediction and inference of flow-duration curves using multi-output neural networks
We develop multi-output neural network models (MNNs) to predict flow-duration curves (FDCs) in 9,203 ungaged locations in the Southeastern United States for six decades between 1950-2009. The model architecture contains multiple response variables in the output layer that correspond to individual quantiles along the FDC. During training, predictions are made for each quantile, and a...

Applying the ecology of aquatic–terrestrial linkages to freshwater and riparian management Applying the ecology of aquatic–terrestrial linkages to freshwater and riparian management
Global stressors such as climate change, invasive species, urbanization, agricultural practices, and pollution can alter aquatic resource subsidies to terrestrial consumers. The effects of these stressors on timing, quality, and quantity of aquatic subsidies, such as adult aquatic insects, to birds, herpetofauna, and mammals, have large implications for wildlife management (Baxter et al...

Coastal Salinity Index along the southeastern Atlantic coast and the Gulf of Mexico, 1983 to 2018 Coastal Salinity Index along the southeastern Atlantic coast and the Gulf of Mexico, 1983 to 2018
Coastal droughts have a different dynamic than upland droughts, which are typically characterized by agricultural, hydrologic, meteorological, and (or) socioeconomic effects. Drought uniquely affects coastal ecosystems because of changes in the salinity conditions of estuarine creeks and rivers. The location of the freshwater-saltwater interface in surface-water bodies is an important...
