Seth Adelsperger, Darren Ficklin, Scott Robeson, Margaret Ann Zimmer, John C. Hammond, Damon M. Hall, J.P. Gannon
2024, Environmental Research Letters (19)
Streamflow droughts are receiving increased attention worldwide due to their impact on the environment and economy. One region of concern is the Midwestern United States, whose agricultural productivity depends on subsurface pipes known as tile drains to improve trafficability and soil conditions for crop growth. Tile drains accomplish this by...

Dryland ecosystems cover 40% of our planet's land surface, support billions of people, and are responding rapidly to climate and land use change. These expansive systems also dominate core aspects of Earth's climate, storing and exchanging vast amounts of water, carbon, and energy with the atmosphere. Despite their indispensable ecosystem...
Modeling the effects of temperature and limiting nutrients on the competition of an invasive floating plant, Pontederia crassipes, with submersed vegetation in a shallow lake
Linhao Xu, Don DeAngelis
2024, Plants (13)
The potential for a non-native plant species to invade a new habitat depends on broadscale factors such as climate, local factors such as nutrient availability, and the biotic community of the habitat into which the plant species is introduced. We developed a spatially explicit model to assess the risk...

Chiqian Zhang, Kyle D. McIntosh, N. Sienkiewicz, Erin A. Stelzer, Jennifer L. Graham, Jingrang Lu
2024, Science of the Total Environment (954)
Phytoplankton overgrowth, which characterizes the eutrophication or trophic status of surface water bodies, threatens ecosystems and public health. Quantitative polymerase chain reaction (qPCR) is promising for assessing the abundance and community composition of phytoplankton. However, applications of qPCR to indicate eutrophication and trophic status, especially in lotic systems, have yet...
Evaluating a process-guided deep learning approach for predicting dissolved oxygen in streams
Jeffrey M Sadler, Lauren Elizabeth Koenig, Galen Gorski, Alice M. Carter, Robert O. Hall Jr.
2024, Hydrological Processes (38)
Dissolved oxygen (DO) is a critical water quality constituent that governs habitat suitability for aquatic biota, biogeochemical reactions and solubility of metals in streams. Recently introduced high-frequency sensors have increased our ability to measure DO, but we still lack the capacity to understand and predict DO concentrations at high spatial...

Ambient flow and transport in long-screened, sand-packed wells: Insights into cross contamination and wellbore flow
Philip Harte, Christopher Palumbo Ely, Nicholas F. Teague, Nicole C. Fenton, Anthony A. Brown
2024, Environmental Earth Sciences (83)
The presence of long-screened wells with a surrounding sand pack can have a major effect on the redistribution of contaminants in groundwater, particularly when the wells are set in low-hydraulic conductivity aquifers. Such redistribution, or cross contamination, can occur through vertical flow and advective transport or by in-well mixing via...
Quantifying aspect-dependent snowpack response to high-elevation wildfire in the southern Rocky Mountains
Wyatt Reis, Daniel McGrath, Kelly Elder, Stephanie Kampf, David M. Rey
2024, Water Resources Research (60)
Increasing wildfire frequency and severity in high-elevation seasonal snow zones presents a considerable water resource management challenge across the western United States (U.S.). Wildfires can affect snowpack accumulation and melt patterns, altering the quantity and timing of runoff. While prior research has shown that wildfire generally increases snow melt rates...

2024, Journal of Geophysical Research Biogeosciences (129)
The seasonal behavior of fluvial dissolved silica (DSi) concentrations, termed DSi regime, mediates the timing of DSi delivery to downstream waters and thus governs river biogeochemical function and aquatic community condition. Previous work identified five distinct DSi regimes across rivers spanning the Northern Hemisphere, with many rivers exhibiting multiple DSi regimes...

Nicole E. Adams, Jared Joseph Homola, Nicholas M. Sard, Lucas R. Nathan, Brian M. Roth, John D. Robinson, Kim T. Scribner
2024, Evolutionary Applications (17)
The establishment and spread of invasive species are directly related to intersexual interactions as dispersal and reproductive success are related to distribution, effective population size, and population growth. Accordingly, populations established by r-selected species are particularly difficult to suppress or eradicate. One such species, the red swamp crayfish (Procambarus clarkii)...

Reexamining the Honolulu Volcanics: Hawai‘i's classic case of rejuvenation volcanism
Michael O. Garcia, Marc D. Norman, Brian Jicha, Kendra J. Lynn, Peng Jiang
2024, Journal of Petrology (65)
Rejuvenated volcanism is a worldwide phenomenon occurring on many oceanic islands in all of the major ocean basins. This plume-related volcanism follows the main edifice-building stage after a hiatus of variable duration (e.g. 0.6–2 Myrs in Hawai'i). The Honolulu Volcanics (HV), the classic case of rejuvenated volcanism, involved monogenetic eruptions...
