The influence of shallow subsurface properties on particle motion in acoustic-seismic coupling The influence of shallow subsurface properties on particle motion in acoustic-seismic coupling
Atmospheric acoustic waves transmit energy into the solid Earth through air-to-ground coupling. These waves are recorded by seismic sensors and provide insight into both atmospheric phenomena and subsurface properties. Interpreting these signals is often challenging because they are modulated by subsurface structure and the incidence angle of the acoustic wave. This study examines...

Continuous and high-resolution longitudinal profiles of the water surface and riverbed elevation for 282 miles of the Colorado River from Lees Ferry to Pearce Ferry, Arizona, 2021 Continuous and high-resolution longitudinal profiles of the water surface and riverbed elevation for 282 miles of the Colorado River from Lees Ferry to Pearce Ferry, Arizona, 2021
Longitudinal profiles of water surface and riverbed elevations capture key geomorphic characteristics that can be affected by water infrastructure and natural processes. Continuous water surface profiles of the Colorado River in Grand Canyon, a river influenced by two of the largest dams in the United States, have been measured infrequently. The water surface profile was first measured...

From start to stop: Simple methods for mapping susceptibility to landslide runout and debris-flow inundation From start to stop: Simple methods for mapping susceptibility to landslide runout and debris-flow inundation
Landslide runout and debris-flow inundation can disrupt areas well beyond their initial sources, causing widespread damage and extensive fatalities. Understanding where they start and how far they might travel is essential in many locations worldwide. However, most landslide susceptibility maps focus on initiation areas and fail to incorporate runout areas. Furthermore, hazards vary...

Streamflow and surface-water presence data availability across the conterminous United States: A review for headwater systems Streamflow and surface-water presence data availability across the conterminous United States: A review for headwater systems
Water is essential for life on Earth, supporting ecosystems, human health, and economic activities. Hydrology relies on observational data, and this paper discusses regional and national datasets for the conterminous United States (CONUS) publicly available as of 2023, focusing on headwaters, defined as first- and second-order streams at 1:24000 scale. It identifies 72 primary and...

Understanding co-invading species’ ecological strategies and interactions with causal inference and simple dynamic models: Bighead (Hypophthalmichthys nobilis) and Silver carp (H. molitrix) in the Illinois River, USA Understanding co-invading species’ ecological strategies and interactions with causal inference and simple dynamic models: Bighead (Hypophthalmichthys nobilis) and Silver carp (H. molitrix) in the Illinois River, USA
Species interactions among multiple invasive species can present hidden challenges for management and eradication efforts. Bighead and Silver carp (Hypophthalmichthys nobilis and H. molitrix, respectively) are closely related species that have co-invaded the Mississippi River and many of its tributaries, including the Illinois River. We used a combination of causal inference and dynamic...

An overview of the NASA Adaptation and Response in Drylands field experiment scoping study An overview of the NASA Adaptation and Response in Drylands field experiment scoping study
Drylands cover 41% of Earth’s land surface, support 36% of the global population, and contribute 60% of global food production. Despite these ecosystems’ importance and high vulnerability to droughts and heatwaves, drylands remain some of the most understudied systems on Earth. Monitoring drylands is challenging due to their complex ecosystem structure of visible soil mixed with diverse...

Bait baskets reduce trap disturbance and rebaiting for invasive Argentine black and white tegus (Salvator merianae) in the Greater Everglades Ecosystem, USA Bait baskets reduce trap disturbance and rebaiting for invasive Argentine black and white tegus (Salvator merianae) in the Greater Everglades Ecosystem, USA
Effective invasive species management can be informed by strategies that maximize removal while minimizing costs. In the southeastern United States, metal-mesh bait baskets are routinely used to protect chicken egg lures in traps targeting invasive Argentine black and white tegu lizards (Salvator merianae). These bait baskets are designed to reduce bait loss and nontarget species...

Expansion trends and impacts of Phragmites australis on the Louisiana Gulf Coast Expansion trends and impacts of Phragmites australis on the Louisiana Gulf Coast
Invasive plant species pose substantial threats to ecosystem integrity by disrupting ecosystem processes, reducing biodiversity, and complicating restoration and management efforts. Non-native lineages of Phragmites australis are invasive in wetlands across parts of North America, causing declines in the diversity of native wetland plants and disrupting biogeochemical cycles. Despite...

Recent spread of introduced swamp eels (Percomorpha, Synbranchiformes, Synbranchidae) in Central Florida, USA, including first documented collections of cuchia, Ophichthys cuchia (Hamilton, 1822), in Florida Recent spread of introduced swamp eels (Percomorpha, Synbranchiformes, Synbranchidae) in Central Florida, USA, including first documented collections of cuchia, Ophichthys cuchia (Hamilton, 1822), in Florida
Swamp eels (Percomorpha, Synbranchiformes, Synbranchidae) were discovered in Florida in the 1990s and were considered established in the Greater Miami and Greater Tampa regions as early as 1997. We report detection of established populations of Sunda swamp eel, Monopterus javanensis Lacepède, 1800 and cuchia, Ophichthys cuchia (Hamilton, 1822) across multiple Orlando area watersheds in...

Growth and erosion of volcanic islands since 1963 analyzed by multi-sensor satellite data and historical records Growth and erosion of volcanic islands since 1963 analyzed by multi-sensor satellite data and historical records
Most volcanic activity is taking place in the oceans. Depending on water depth, eruption recurrence times and volumes, a new island can form. The power of erosional forces, the type of erupted material and the efficiency of secondary processes determine the island’s lifetime. Since the famous eruption of Surtsey (Iceland) in 1963, at least another 23 volcanic islands have appeared. Some...

Extreme droughts shrink suitable habitats and reduce fitness for large mammals in the American West Extreme droughts shrink suitable habitats and reduce fitness for large mammals in the American West
Droughts are intensifying across the biosphere, yet the consequences of this phenomenon for wildlife habitat suitability and fitness are poorly studied. We analyzed 12 years of GPS telemetry data for three large mammal species—herbivorous mule deer (N = 2854), omnivorous black bears (N = 103), and carnivorous cougars (N = 105)—to evaluate the effects of drought on each species’ habitat...

Restoring dryland water cycles for precipitation feedback and climate stability; a review Restoring dryland water cycles for precipitation feedback and climate stability; a review
Drylands across the globe are experiencing intensifying water scarcity, land degradation, and hydroclimatic extremes. This review integrates evidence from multidecadal field studies, hydrologic monitoring, geomorphic and ecological assessments, remote sensing, and land–atmosphere science to evaluate how restoration influences key components of the terrestrial water cycle. Low-tech...
