Water-budget accounting for tropical regions model (WATRMod) documentation
Delwyn S. Oki
2022, Open-File Report 2022-1013
Regional groundwater recharge commonly is estimated using a threshold-type water-budget approach in which groundwater recharge is assumed to occur when water in the plant-root zone exceeds the soil’s moisture storage capacity. A water budget of the plant-soil system accounts for water inputs (rainfall, fog interception, irrigation, septic-system leachate, and other...

Snake fungal disease (SFD; ophidiomycosis), caused by the pathogen Ophidiomyces ophiodiicola (Oo), has been documented in wild snakes in North America and Eurasia, and is considered an emerging disease in the eastern United States of America. However, a lack of historical disease data has made it challenging to determine whether Oo is a recent...
North Carolina and Landsat
U.S. Geological Survey
2022, Fact Sheet 2022-3038
North Carolina’s rich history and importance in the colonial days played a critical role in the Nation’s economic development. It was also the setting for events like the Wright Brothers’ famous first flight of a powered aircraft, called “Wright Flyer,” which took place in Kitty Hawk in 1903. Today, North...
Late Paleozoic flexural extension and overprinting shortening in the southern Ozark dome, Arkansas, USA: Evolving fault kinematics in the foreland of the Ouachita orogen
Mark R. Hudson, Kenzie J. Turner
2022, Tectonics (41)
Faults and folds on the southern flank of the Ozark dome in northern Arkansas, USA, record flexural extension in a foreland area followed by shortening in response to the late Paleozoic Ouachita orogeny. Map-scale structures and an analysis of fault-slip data collected systematically during geologic mapping demonstrate that most deformation...

2022, Management of Biological Invasions (13) 344-368
Environmental (e)DNA tools are sensitive and cost-effective for early detection of invasive species. However, the uncertainty associated with the interpretation of positive eDNA detections makes it challenging to determine appropriate natural resource management responses. Multiple sources of error can give rise to positive detections of eDNA in a sample when...
Overturning stereotypes: The fuzzy boundary between recreational and subsistence inland fisheries
Elizabeth A. Nyboer, Holly Susan Embke, Ashley Robertson, Robert Arlinghaus, Shannon D. Bower, Claudio Baigun, T. Douglas Beard Jr., Steve J. Cooke, Ian. G. Cowx, John D. Koehn, Roman Lyach, Marco Milardi, Warren M. Potts, Abigail Lynch
2022, Fish and Fisheries (23) 1282-1298
Inland recreational fisheries provide numerous socio- economic benefits to fishers, families and communities. Recreationally harvested fish are also frequently consumed and may provide affordable and sustainable but undervalued contributions to human nutrition. Quantifying the degree to which recreationally harvested fish contribute to food security and subsistence is impeded by lack...

2022, Research Note RMRS-RN-93
Wildfire affects many types of communities and is a particular concern for communities in the wildland urban interface (WUI), such as those of Teton County, Wyoming. The core intent of this project was to provide evidence to support the Teton Area Wildfire Protection Coalition (TAWPC) and affiliated organizations in their...
Evolving magma temperature and volatile contents over the 2008–2018 summit eruption of Kīlauea Volcano
Joshua Allen Crozier, Leif Karlstrom
2022, Science Advances (8)
Magma rheology and volatile contents exert primary and highly nonlinear controls on volcanic activity. Subtle changes in these magma properties can modulate eruption style and hazards, making in situ inference of their temporal evolution vital for volcano monitoring. Here, we study thousands of impulsive magma oscillations within the shallow conduit...
Luminescence sediment tracing reveals the complex dynamics of colluvial wedge formation
Harrison J. Gray, Christopher DuRoss, Sylvia Nicovich, Ryan D. Gold
2022, Science (8)
Paleoearthquake studies that inform seismic hazard rely on assumptions of sediment transport that remain largely untested. Here, we test a widespread conceptual model and a new numerical model on the formation of colluvial wedges, a key deposit used to constrain the timing of paleoearthquakes. We perform this test by applying...
Newly documented behavior of free-ranging Arctic wolf pups
L. David Mech
2022, Arctic (75) 272-276
Whereas much is known about the behavior and development of captive young wolf (Canis lupus) pups, less detail has been published about some aspects of free-ranging wolf pup behavior. This article synthesizes 42 observations of free-ranging Arctic wolf pups from ages 13 through 52 days made during 10 summers from...
Inversion of induced polarization-affected towed-transient electromagnetic data in a lateritic regolith geology: A case study from western Tanzania
Pradip Kumar Maurya, Denys Grombacher, John W. Lane, Johan Lind, Esben Auken
2022, Geophysics (87) B247-B254
For several decades, induced polarization (IP) effects on transient electromagnetic (TEM) responses have been observed. These effects can manifest as late-time negative transients or as rapidly decaying curves and are usually associated with highly polarizable bodies. If neglected, IP effects can lead to erroneous resistivity models. Recent work allows IP...

Modeling and estimating co-occurrence between the invasive Shiny Cowbird and its Puerto Rican hosts
Philip T. Patton, Krishna Pacifici, Jaime A. Collazo
2022, Biological Invasions (24) 2951-2960
Invasive species threaten island biodiversity globally. For example, the Shiny Cowbird (Molothrus bonariensis) parasitizes many of Puerto Rico’s endemic species, particularly in the open forests in the island’s southwest. Less is known, however, about cowbird parasitism in the agro-ecological highlands, which contain a patchwork of forests, shaded-coffee plantations, and coffee...

River Metabolism Estimation Tools (RiverMET) with demo in the Illinois River Basin
Jay Choi, Katherine Michelle Bernabe Quion, Ariel Reed, Judson Harvey
2022, ESSOAr
Ecosystem metabolism quantifies the rate of production, maintenance, and decay of organic matter in terrestrial and aquatic systems. It is a fundamental measure of energy flow associated with biomass production by photosynthesizing organisms and biomass oxidation by respiring plants, animals, algae, and bacteria (Bernhardt et al., 2022) . Ecosystem metabolism...
Hydrologic controls on peat permafrost and carbon processes: New insights from past and future modeling
Claire C. Treat, Miriam C. Jones, Jay R. Alder, Steve Frolking
2022, Frontiers in Environmental Science (10)
Soil carbon (C) in permafrost peatlands is vulnerable to decomposition with thaw under a warming climate. The amount and form of C loss likely depends on the site hydrology following permafrost thaw, but antecedent conditions during peat accumulation are also likely important. We test the role of differing...

2022, Limnology and Oceanography Letters (7) 321-331
Sea level rise (SLR) and saltwater intrusion are driving inland shifts in coastal ecosystems. Here, we make high-resolution (1 m) predictions of land conversion under future SLR scenarios in 81 watersheds surrounding Chesapeake Bay, United States, a hotspot for accelerated SLR and saltwater intrusion. We find that...
