2024, Bulletin of Volcanology (86)
The unprecedented 2018 summit collapse at Kīlauea and subsequent 2020–2021 eruption within the newly deepened Halema‘uma‘u Crater provide an unparalleled opportunity to understand how collapse events impact a volcano’s shallow reservoir system and magmatic processes. Glass and olivine from tephra ejected by lava fountains and several...

The deep sea is the largest biome on earth, but one of the least studied despite its critical role in global carbon cycling and climate buffering. Deep-sea organisms largely rely on particulate organic matter from the surface ocean for energy –...
Predicting redox conditions in groundwater at a national scale using random forest classification
Anthony J. Tesoriero, Susan Wherry, Danielle Dupuy, Tyler D. Johnson
2024, Environmental Science and Technology (58) 5079-5092
Redox conditions in groundwater may markedly affect the fate and transport of nutrients, volatile organic compounds, and trace metals, with significant implications for human health. While many local assessments of redox conditions have been made, the spatial variability of redox reaction rates makes the determination of redox conditions at regional...

Melissa Moulton, Joseph B. Zambon, Zuo Xue, John C. Warner, Daoyang Bao, Dongxiao Yin, Zafer Defne, Ruoying He, Christie Hegermiller
2024, Journal of Geophysical Research: Oceans (129)
Extreme precipitation during Hurricane Florence, which made landfall in North Carolina in September 2018, led to breaches of hog waste lagoons, coal ash pits, and wastewater facilities. In the weeks following the storm, freshwater discharge carried pollutants, sediment, organic matter, and debris to the coastal ocean, contributing...
Temperature impacts on dengue incidence are nonlinear and mediated by climatic and socioeconomic factors: A meta-analysis

2024, PLOS Climate (3)
Temperature can influence mosquito-borne diseases like dengue. These effects are expected to vary geographically and over time in both magnitude and direction and may interact with other environmental variables, making it difficult to anticipate changes in response to climate change. Here, we investigate global variation in...

Evaluating the context dependency of large river nursery habitats for fishes in the lower Red River catchment
Paul Q. Ramsey, John Dattilo, Dennis DeVries, Shannon K. Brewer
2024, River Research and Applications (40) 761-779
Both fine- and coarse-scale physicochemical conditions affect the quantity and quality of nursery habitats within riverine ecosystems. Nursery habitats in large, braided, and sandbed streams such as the lower Red River of Oklahoma, Texas, and Arkansas are not well described and likely vary among species. Identification of nursery habitats is...

For...
Unravelling spatial heterogeneity of inundation pattern domains for 2D analysis of fluvial landscapes and drainage networks
Pierfranco Costabile, Carmelina Costanzo, Margherita Lombardo, Ethan J. Shavers, Larry Stanislawski
2024, Journal of Hydrology (632)
Fluvial landscape analysis is an essential part of geomorphology, hydrology, ecology, and cartography. It is traditionally focused on the transition between hillslopes and channel domain, in which the network drainage is represented by static flow lines. However, the natural fluctuations of the processes occurring in the watershed induce lateral and...

Alexi Lainis, Roseanna M. Neupauer, Joshua C. Koch, Michael Gooseff
2024, Hydrological Processes (38)
Aufeis (also known as icings) are large sheet-like masses of layered ice that form in river channels in arctic environments in the winter as groundwater discharges to the land surface and subsequently freezes. Aufeis are important sources of water for Arctic river ecosystems, bolstering late...

Eric Swain, James E. Landmeyer, Michael A. Singletary , Shannon E. Provenzano
2024, Hydrology (11)
Past waste-disposal activities at Naval Air Station Whiting Field (NASWF) have led to elevated concentrations of contaminants in the underlying sand and gravel aquifer. Contaminants include two of the most commonly detected chemicals in groundwater in many countries (benzene and trichloroethylene (TCE)) and the “forever chemicals” per- and poly-fluoroalkyl...
Characterization of change in tree cover state and condition over the conterminous United States
Francis K Dwomoh, Roger F. Auch
2024, Forests (15)
Variability in the effects of disturbances and extreme climate events can lead to changes in tree cover over time, including partial or complete loss, with diverse ecological consequences. It is therefore critical to identify in space and time the change processes that lead to tree cover change. Studies of...

Southern fox squirrel and eastern gray squirrel interactions in a fire-maintained ecosystem
M.H. Guill, J.L. De La Cruz, M. Puckett, S.D. Klopfer, B. Martin, W. Mark Ford
2024, Journal of the Southeastern Association of Fish and Wildlife Agencies (11) 215-222
Southern fox squirrels (Sciurus niger niger) have been declining due to habitat fragmentation, cover type conversion, and fire suppression in the Southeast. A decrease in growing season burns has led to hardwood encroachment and forest mesophication that benefit the competing eastern gray squirrels (S. carolinensis). In the southern Coastal Plain...
Seasonal activity patterns of northern long-eared bats on the coastal Mid-Atlantic
Jesse L. De La Cruz, Nicholas J. Kalen, Elaine L. Barr, Emily D. Thorne, Alexander Silvis, Richard J. Reynolds, W. Mark Ford
2024, Journal of the Southeastern Association of Fish and Wildlife Agencies (11) 185-195
Conservation of bats declining from white-nose syndrome (WNS) impacts requires an understanding of both temporal and landscape-level habitat relationships. Traditionally, much of the research on bat ecology has focused on behavior of summer maternity colonies within species’ distribution cores, including that of the endangered northern long-eared bat (Myotis septentrionalis). To...

2024, Report
Coastal wetlands exist in the narrow fringe between uplands and open water and consequently, are uniquely vulnerable to the impacts of sea level rise (SLR). Predictive models suggest that in the coming decades sea level rise will lead to substantial losses of coastal wetland habitat in North Carolina. Empirical measurements...
