A synthesis of freshwater forested wetland soil organic carbon storage
Yadav Sapkota, Jacob F. Berkowitz, Camille Stagg, Ryan R. Busby
2025, Frontiers in Forests and Global Change (8)
Freshwater forested wetlands account for ~76% (918 M ha) of the total global wetland extent. However, freshwater forested wetlands are difficult to distinguish from upland forest due to canopy coverage, the abundance of wetland-nonwetland mosaics, seasonal hydropatterns, and fewer readily observable connections to large surface water bodies relative to marshes and other...
Estimating indicators of cyanobacterial harmful algal blooms in New York State
Philip Savoy, Rebecca Michelle Gorney, Jennifer L. Graham
2025, Ecological Indicators (173)
Cyanobacteria harmful algal blooms (cyanoHABs) are a global concern for aquatic ecosystem and human health. Limited funding for monitoring programs and inconsistent determination of cyanoHAB occurrence present challenges for identifying commonly effective variables for characterizing cyanoHABs and the development of generalized models. We compiled a combination of water quality measurements,...
Neural network-based temporal ensembling of water depth estimates derived from SuperDove Images
Milad Niroumand-Jadidi, Carl J. Legleiter, Francesca Bovolo
2025, Remote Sensing (17)
CubeSats provide a wealth of high-frequency observations at a meter-scale spatial resolution. However, most current methods of inferring water depth from satellite data consider only a single image. This approach is sensitive to the radiometric quality of the data acquired at that particular instant in time, which could be degraded...
Uncertainty quantification of geophysical and hydrologic parameters estimated from borehole nuclear magnetic resonance data
Burke J. Minsley, Stephanie N. Phillips, Stephanie R. James
2025, JGR Machine Learning and Computation (2)
Borehole nuclear magnetic resonance (bNMR) data are typically used to infer in situ hydrologic properties. Partial water content as a function of pore size is estimated by fitting the measured NMR response to a multi-exponential T2 distribution, and the sum of estimated T2 amplitudes equals the total volumetric water content. From these estimated parameters,...

Linking tidal-creek sediment fluxes to vertical sediment accretion in a restored salt marsh
Daniel J. Nowacki, Jessica R. Lacy, SeanPaul La Selle
2025, Earth Surface Processes and Landforms (50)
Despite growing interest and investment in salt-marsh restoration, relatively few marshes subjected to restoration efforts have been systematically monitored to assess physical restoration trajectory or success. In south San Francisco Bay, CA, USA, where 83% of wetlands were lost via human manipulation, the largest wetland restoration effort on the U.S....

2025, Journal of Aquatic Animal Health (37) 21-33
ObjectiveThe Blue Catfish Ictalurus furcatus is commonly raised in warmwater aquaculture in the United States to produce Channel Catfish I. punctatus × Blue Catfish hybrids. It is also a prominent aquatic invasive species of concern in the mid-Atlantic region of the United States. Here, Yersina ruckeri was isolated from moribund Blue Catfish...
Nanometer-scale relationships between sedimentary organic matter molecular composition, fluorescence, cathodoluminescence, and reflectance: The importance of oxygen content at low thermal maturities
Aaron M. Jubb, Paul C. Hackley, Ryan J. McAleer, Jing Qu
2025, Organic Geochemistry (204)
Molecular characterization of sedimentary organic matter (SOM), termed macerals, is a common goal when seeking to understand petroleum generation as well as other geologic processes in deep time. However, unambiguous measurement of discrete macerals is challenging due to the small size of organic particles in sedimentary rocks, the proximity of...
Streamflow response to glacier mass loss varies with basin precipitation across Alaska
Janet H. Curran, Brianna Rick, Jeremy S. Littell, Louis C. Sass
2025, Water Resources Research (61)
Diminishing glaciers affect streamflow, and given the extent of glaciers in Alaska and adjacent Canada, continued glacier mass loss is likely to have profound effects on ecosystems sensitive to runoff. The effects of glacier mass loss on streamflow are likely to vary across the wide ranges of basin size, glacier...
Optimizing control of a freshwater invader in time and space
Jessica O. Diallo, Sarah J. Converse, Matthew Chmiel, Andy Stites, Julian D. Olden
2025, Ecological Applications (35)
The global spread of invasive species in aquatic ecosystems has prompted population control efforts to mitigate negative impacts on native species and ecosystem functions. Removal programs that optimally allocate removal effort across space and time offer promise for improving invader suppression or eradication, especially given the limited resources available to...
Multiyear crop residue cover mapping using narrow-band vs. broad-band shortwave infrared satellite imagery
Brian T. Lamb, W. Dean Hively, Jyoti Jennewein, Alison Thieme, Alexander M. Soroka, Leticia Santos, Daniela Jones, Steven Mirsky
2025, Soil and Tillage Research (251)
Crop residue serves an important role in agricultural systems as high levels of fractional crop residue cover (fR) can reduce erosion, preserve soil moisture, and build soil organic carbon. However, the ability to accurately quantify fR at scale has been limited. In this study we produced annual maps of fR for farmland in Maryland,...

Melia G. Nafus, Levi Gray, Page E. Klug, Gordon H. Rodda, Scott Michael Goetz
2025, Wildlife Research (52)
ContextAnimals may adjust their behavior in predictable ways to balance tradeoffs between resource acquisition and survival or fecundity. Microhabitat selection based on individual traits or environmental conditions is one measure of risk–reward tradeoffs by individuals.AimsWe used data from observational and manipulative studies to investigate whether an...
Fossil diatoms in Arctic marine surface sediments
Christof Pearce, Beth Elaine Caissie, Alice Carter-Champion, Audrey Limoges, Tiia Luostarinen, Gavin L. Simpson, Kaarina Weckstrom
2025, Newsletter
Diatoms are one of the main constituents of marine phytoplankton in the Arctic, and thanks to their siliceous skeletons, diatom fossils are relatively well preserved in sediments. Due to their species-specific sensitivity to different ocean conditions, their abundance and assemblages in sediments are routinely used by paleoceanographers to reconstruct the...
Balancing monitoring and management in the adaptive management of an invasive species
Brielle K. Thompson, Julien Olden, Sarah J. Converse
2025, Ecology and Evolution (15)
Efficient allocation of managers' limited resources is necessary to effectively control invasive species, but determining how to allocate effort between monitoring and management over space and time remains a challenge. In an adaptive management context, monitoring data are key for gaining knowledge and iteratively improving management, but monitoring costs money....
Uncertainty reduction for subaerial landslide-tsunami hazards
Katherine R. Barnhart, David L. George, Andrew L. Collins, Lauren N. Schaefer, Dennis M. Staley
2025, Journal of Geophysical Research: Earth Surface (130)
Subaerial rock slopes may generate a tsunami by rapidly moving into the water. Large uncertainty in landslide characteristics propagates into large uncertainty in tsunami hazard, making hazard assessment more difficult for land and emergency managers. Once a potentially tsunamigenic landslide is identified, it may not be clear which landslide characteristics...
Evaluating the applicability of the generalized power-law rating curve model: With applications to paired discharge-stage data from Iceland, Sweden, and the United States
Rafael Daniel Vias, Birgir Hrafnkelsson, Timothy O. Hodson, Sölvi Rögnvaldsson, Axel Örn Jansson, Sigurdur M. Gardarsson
2025, Journal of Hydrology (651)
Hydrologic research and operations make extensive use of streamflow time series. In most applications, these time series are estimated from rating curves, which relate flow to some easy-to-measure surrogate, typically stage. The conventional stage-discharge rating takes the form of a segmented power law, with one segment for each hydrologic control...

2025, Herpetologica (81) 141-151
Translocated herpetofauna can exhibit irregular space use and movement patterns when compared with resident conspecifics. In Florida, USA, Gopher Tortoises (Gopherus polyphemus) are translocated throughout the state to mitigate habitat loss due to development. The postrelease space use of translocated Gopher Tortoises within soft-release pens can affect population dynamics and...
