Informing ASR treatment practices in a Florida aquifer through a human health risk approach
Anna Gitter, Kristina Mean, John T. Lisle
2023, International Journal of Enviornmental Research and Public Health (20)
Aquifer storage and recovery (ASR) can augment water supplies and hydrologic flows under varying climatic conditions. However, imposing drinking water regulations on ASR practices, including pre-treatment before injection into the aquifer, remains arguable. Microbial inactivation data—Escherichia coli, Pseudomonas aeruginosa, poliovirus type 1 and Cryptosporidium parvum—were used in a...
Evidence for fine-grained material at lunar red spots: Insights from thermal infrared and radar data sets
Benjamin Byron, Catherine Elder, Timothy Glotch, Paul O. Hayne, Lori M. Pigue, Joshua T. S. Cahill
2023, Planetary Science Journal (4)
Lunar red spots are small spectrally red features that have been proposed to be the result of non-mare volcanism. Studies have shown that a number of red spots are silicic, and are spectrally distinct from both highlands and mare compositions. In this work, we use data from LRO Diviner, Mini-RF,...
Doing the same thing over and over again and getting the same result: Assessing variance in wetland invertebrate assemblages
Sophie Reindl, Kyle McLean, Jamie M. Kneitel, Douglas A. Bell, Darold P. Batzer
2023, Wetlands (43)
Past efforts to explain variation of invertebrate assemblages in freshwater wetlands have been less productive than anticipated. To explore why efforts are disappointing, we assembled large invertebrate data sets from North Dakota prairie potholes, California rock pools, and Georgia Carolina bay wetlands that addressed spatial (among wetlands) and temporal (among...

Paul J. Rudershausen, Steven M. Lombardo, George R. Stilson, Matthew J. O'Donnell
2023, Marine Ecologly Progressive Series (719) 92
Organisms that rely on salt marsh habitat are an important trophic link, helping to maintain estuarine ecosystem productivity. We used GIS to quantify intertidal (assumed salt marsh) area from aerial photographs taken in 1939 and from software-supplied satellite imagery taken in 2021 for tidal creeks in North Carolina (USA)...

Avery Paxton, Tom Swannack, Candice Piercy, Safra Altman, Leanne Poussard, Brandon Puckett, Curt D. Storlazzi, T. Shay Viehman
2023, Environmental Evidence (12)
BackgroundShallow, tropical coral reefs face compounding threats from habitat degradation due to coastal development and pollution, impacts from storms and sea-level rise, and pulse disturbances like blast fishing, mining, dredging, and ship groundings that reduce coral reefs’ height and variability. One approach toward restoring coral reef structure from...
Leaf nitrogen affects photosynthesis and water use efficiency similarly in nitrogen-fixing and non-fixing trees
Thomas A. Bytnerowicz, Jennifer L. Funk, Duncan N. L. Menge, Steven S. Perakis, Amelia A. Wolf
2023, Journal of Ecology (111) 2457-2471
Nitrogen (N)-fixing trees are thought to break a basic rule of leaf economics: higher leaf N concentrations do not translate into higher rates of carbon assimilation. Understanding how leaf N affects photosynthesis and water use efficiency (WUE) in this ecologically important group is critical.We grew six N-fixing and four...

Richard J. Camp, Chauncey K. Asing, Paul C. Banko, Lainie Berry, Kevin W. Brinck, Chris Farmer, Ayesha Genz
2023, Wildlife Society Bulletin (47)
Effective species management and conservation benefit from knowledge of species distribution and status. Surveys to obtain that information often involve replicate sampling, which increases survey effort and costs. We simultaneously modeled species distribution, abundance and spatial correlation, and compared the uncertainty in replicate abundance estimates of the endangered palila (Loxioides...

Lisamarie Windham-Myers
Michael J. Kennish, Hans W. Paerl, Joseph Crosswell, editor(s)
2023, Book chapter, Climate change and estuaries
Blue carbon, a convenient term to encompass the climate mitigation value of coastal carbon dynamics, has received global policy attention and growing datasets to support management actions. Carbon stock assessments in mangroves, seagrass, and tidal marshes document significant carbon storage in soils. Models illustrate significant downward fluxes of carbon dioxide...

Samuel Pecoraro, Peter C. Esselman, Timothy P. O’Brien, Steve A. Farha, David Warner
2023, Journal of Great Lakes Research (49) 1204-1210
Acoustic seabed classification (ASC) is an important method for understanding landscape-level physical and biological patterns in the aquatic environment. Bottom habitats in the Laurentian Great Lakes are poorly mapped to date, and will require a variety of contributors and data sources to complete. We repurposed a long-term split-beam echosounder dataset...
