Representation of surface-water flows using Gradient-Related Discharge in an Everglades Network Representation of surface-water flows using Gradient-Related Discharge in an Everglades Network
The Everglades Depth Estimation Network interpolates water-level gage data to produce daily water-level elevations for the Everglades in south Florida. These elevations were used to estimate flow vectors (gradients and directions) and volumetric flow rates using the Gradient-Related Discharge in an Everglades Network (GARDEN) application developed by the U.S. Geological Survey in...

Mammalian lures monitored with time-lapse cameras increase detection of pythons and other snakes Mammalian lures monitored with time-lapse cameras increase detection of pythons and other snakes
Background Enhancing detection of cryptic snakes is critical for the development of conservation and management strategies; yet, finding methods that provide adequate detection remains challenging. Issues with detecting snakes can be particularly problematic for some species, like the invasive Burmese python (Python bivittatus) in the Florida Everglades.Methods Using multiple survey...

Assessing the vertical accuracy of digital elevation models by quality level and land cover Assessing the vertical accuracy of digital elevation models by quality level and land cover
The vertical accuracy of elevation data in coastal environments is critical because small variations in elevation can affect an area’s exposure to waves, tides, and storm-related flooding. Elevation data contractors typically quantify the vertical accuracy of lidar-derived digital elevation models (DEMs) on a per-project basis to gauge whether the datasets meet quality and accuracy...

Projected sea-level rise and high tide flooding at De Soto National Memorial, Florida Projected sea-level rise and high tide flooding at De Soto National Memorial, Florida
Introduction National parks and preserves in the South Atlantic-Gulf Region contain valuable coastal habitats such as tidal wetlands and mangrove forests, as well as irreplaceable historic buildings and archeological sites located in low-lying areas. These natural and cultural resources are vulnerable to accelerated sea-level rise and escalating high tide flooding events. Through a...

Signatures of wave erosion in Titan’s coasts Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it is unclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theoretical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion, but the observational evidence of waves is indirect, and...

Demographics of a previously undocumented diamondback terrapin (Malaclemys terrapin) population Demographics of a previously undocumented diamondback terrapin (Malaclemys terrapin) population
Coastal habitats are some of the most imperiled due to climate change and anthropogenic activities. As such, it is important to understand population dynamics of the species that may play a role in regulating coastal systems. Diamondback terrapins in Northwest Florida have been understudied, which has resulted in a gap in our knowledge for this region. To help fill this gap, we conducted...

Spatial patterns as long transients in submersed-floating plant competition with biocontrol Spatial patterns as long transients in submersed-floating plant competition with biocontrol
A cellular automata model was developed and parameterized to test the effectiveness of application of biological control insects to water hyacinth (Pontederia crassipes), which is an invasive floating plant species in many parts of the world and outcompetes many submersed native aquatic species in southern Florida. In the model, P. crassipes was allowed to compete with Nuttall’s...

Climate driven trends in historical extreme low streamflows on four continents Climate driven trends in historical extreme low streamflows on four continents
Understanding temporal trends in low streamflows is important for water management and ecosystems. This work focuses on trends in the occurrence rate of extreme low-flow events (5- to 100-year return periods) for pooled groups of stations. We use data from 1,184 minimally altered catchments in Europe, North and South America, and Australia to discern historical climate-driven trends in...

Visualizing wading bird optimal foraging decisions with aggregation behaviors using individual-based modeling Visualizing wading bird optimal foraging decisions with aggregation behaviors using individual-based modeling
Foragers on patchy landscapes must efficiently balance time between searching for and consuming resources to meet their daily energetic requirements. Spatial aggregation foraging behaviors may improve foraging efficiency by sharing information on locations of resource hotspots. Wading birds are an example of patch foragers that form colonial aggregations during the breeding season to...

Evaluation of short-term mussel test for estimating toxicity Evaluation of short-term mussel test for estimating toxicity
Effect concentrations of ammonia, nickel, sodium chloride, and potassium chloride from short-term 7-day tests were compared to those from standard chronic 28-day toxicity tests with juvenile mussels (fatmucket, Lampsilis siliquoidea) to evaluate the sensitivities of the 7-day tests. The effect concentrations for nickel (59 µg Ni/L), chloride (316–519 mg Cl/L, a range from multiple tests)...

Artificial intelligence applied to big data reveals that lake invasions are predicted by human traffic and co-occurring invasions Artificial intelligence applied to big data reveals that lake invasions are predicted by human traffic and co-occurring invasions
Preventing the spread of aquatic invasive species is an important management action. Identifying the characteristics of lakes that are susceptible to invasion creates an opportunity for management groups to prioritize limited resources for high-risk areas. In this study, we leveraged big data from a popular fishing app and other publicly available sources of environmental and human-use...

National Aquatic Environmental DNA Strategy National Aquatic Environmental DNA Strategy
Aquatic life is the engine of ecosystems and economies. In environments ranging from freshwater through marine, this biodiversity underpins the health, culture, opportunities, and economic wellbeing of the Nation -- from local communities to the entire country. The ability to evaluate the status, trends, and future projections of nature is key to maintaining national prosperity, and this...
