Linhao Xu, Don DeAngelis
2024, Theoretical Ecology (17) 185-202
A cellular automata model was developed and parameterized to test the effectiveness of application of biological control insects to water hyacinth (Pontederia crassipes), which is an invasive floating plant species in many parts of the world and outcompetes many submersed native aquatic species in southern Florida....

Understanding temporal trends in low streamflows is important for water management and ecosystems. This work focuses on trends in the occurrence rate of extreme low-flow events (5- to 100-year return periods) for pooled groups of stations. We use data from 1,184 minimally altered catchments in Europe, North and South America,...
Visualizing wading bird optimal foraging decisions with aggregation behaviors using individual-based modeling
Simeon Yurek, Donald L. DeAngelis, Hyo Won Lee, Stephen Tennenbaum
2024, Ecological Modelling (493)
Foragers on patchy landscapes must efficiently balance time between searching for and consuming resources to meet their daily energetic requirements. Spatial aggregation foraging behaviors may improve foraging efficiency by sharing information on locations of resource hotspots. Wading birds are an example of patch foragers that form colonial aggregations during the...

Mackenzie K. Marti, Thomas M. Over
2024, Scientific Investigations Report 2023-5064-B
This report characterizes changes in peak streamflow in Illinois and the relation of these changes to climatic variability, and provides a foundation for future studies that can address nonstationarity in peak-flow frequency analysis in Illinois. Records of annual peak and daily streamflow at streamgages and gridded monthly climatic data (observed...
Catchment coevolution and the geomorphic origins of variable source area hydrology
David G Litwin, Gregory E. Tucker, Katherine R. Barnhart, Ciaran Harman
2024, Water Resources Research (60)
Features of landscape morphology—including slope, curvature, and drainage dissection—are important controls on runoff generation in upland landscapes. Over long timescales, runoff plays an essential role in shaping these same features through surface erosion. This feedback between erosion and runoff generation suggests that modeling long-term landscape evolution together...
Did steam boost the height and growth rate of the giant Hunga eruption plume?
Larry G. Mastin, Alexa R. Van Eaton, Shane Cronin
2024, Bulletin of Volcanology (86)
The eruption of Hunga volcano on 15 January 2022 produced a higher plume and faster-growing umbrella cloud than has ever been previously recorded. The plume height exceeded 58 km, and the umbrella grew to 450 km in diameter within 50 min. Assuming an umbrella thickness of...

2024, Conservation Genetics (25) 1021-1033
Understanding genetic structure and diversity among remnant populations of rare species can inform conservation and recovery actions. We used a population genetic framework to spatially delineate gene pools and estimate gene flow and effective population sizes for the endangered California Freshwater Shrimp Syncaris pacifica. Tissues of 101...
Diel temperature signals track seasonal shifts in localized groundwater contributions to headwater streamflow generation at network scale
David M. Rey, Danielle K. Hare, Jennifer H. Fair, Martin A. Briggs
2024, Journal of Hydrology (639)
Groundwater contributions to streamflow sustain aquatic ecosystem resilience; streams without significant groundwater inputs often have well-coupled air and water temperatures that degrade cold-water habitat during warm low flow periods. Widespread uncertainty in stream-groundwater connectivity across space and time has created disparate...
Artificial intelligence applied to big data reveals that lake invasions are predicted by human traffic and co-occurring invasions
Jessica L. Weir, Wesley Daniel, Kieran Hyder, Christian Skov, Paul A. Venturelli
2024, Biological Invasions (26) 3163-3178
Preventing the spread of aquatic invasive species is an important management action. Identifying the characteristics of lakes that are susceptible to invasion creates an opportunity for management groups to prioritize limited resources for high-risk areas. In this study, we leveraged big data from a popular fishing app and other publicly...
Reproducing age variability in grass carp egg samples from the lower Sandusky River, Ohio, USA, using an egg-drift model
David Soong, P. Ryan Jackson, Patrick M. Kocovsky, Lori Morrison, Tatiana Garcia, Santiago Santacruz, Cindy Chen, Zhenduo Zhu, Holly Susan Embke
2024, Journal of Great Lakes Research (50)
Invasive grass carp (Ctenopharyngodon idella) are currently reproducing in several tributaries to Lake Erie and threatening the Great Lakes ecosystem and fisheries. Grass carp are pelagic river spawners whose fertilized eggs drift downstream from the spawning site, developing as they drift. Variability in spawning time and location together with nonuniform...
Responses of marginal and intrinsic water-use efficiency to changing aridity using FLUXNET observations
Koong Yi, Kimberly A. Novick, Quan Zhang, Lixin Wang, Taehee Hwang, Xi Yang, Kanishka Mallick, Martin Beland, Gabriel B. Senay, Dennis Baldocchi
2024, Journal of Geophysical Research Biogeosciences (129)
According to classic stomatal optimization theory, plant stomata are regulated to maximize carbon assimilation for a given water loss. A key component of stomatal optimization models is marginal water-use efficiency (mWUE), the ratio of the change of transpiration to the change in carbon assimilation. Although the mWUE is often assumed...

2024, Restoration Ecology (32)
Conservation translocations may be a useful tool for the restoration of declining freshwater invertebrates, but they are poorly represented in the literature. We conducted a before-after/control-impact (BACI) experiment to test the efficacy of conservation translocation for re-establishing abundant populations of the amphipod Gammarus lacustris, a...

2024, Weather and Climate Extremes (45)
Drought is one of the key drivers of food insecurity in Afghanistan, which is among the most food insecure countries in the world. In this study, we build on previous research and seek to answer the central question: “What is the influence of El Niño-Southern Oscillation (ENSO) on drought outlooks and agricultural...

Roy E. Petrakis, Laura M. Norman, Miguel L. Villarreal, Gabriel B. Senay, MacKenzie Friedrichs, Florance Cassassuce, Florent Gomis, Pamela L. Nagler
2024, Remote Sensing (16)
Estimates of actual evapotranspiration (ETa) are valuable for effective monitoring and management of water resources. In areas that lack ground-based monitoring networks, remote sensing allows for accurate and consistent estimates of ETa across a broad scale—though each algorithm has limitations (i.e., ground-based validation, temporal consistency, spatial resolution). We developed an...

2024, Scientific Investigations Report 2024-5034
The groundwater below the Red Hill Bulk Fuel Storage Facility (the facility) in Oʻahu, Hawaiʻi, contains fuel compounds from past spills. This study used carbon-14 analyses to distinguish fuel-derived carbon from background carbon, along with other biodegradation indicators, to address two goals: (1) determine the extent and migration direction of...
Potential hazards of polycyclic aromatic hydrocarbons in Great Lakes tributaries using water column and porewater passive samplers and sediment wquilibrium partitioning
Austin K. Baldwin, Steven R. Corsi, David A. Alvarez, David L. Villeneuve, Gerald T. Ankley, Brett R. Blackwell, Marc A. Mills, Peter L. Lenaker, Michelle A. Nott
2024, Environmental Toxicology and Chemistry (43) 1509-1523
The potential for polycyclic aromatic hydrocarbon (PAH)-related effects in benthic organisms is commonly estimated from organic carbon-normalized sediment concentrations based on equilibrium partitioning (EqP). Although this approach is useful for screening purposes, it may overestimate PAH bioavailability by orders of magnitude in some sediments, leading to inflated exposure estimates and...

2024, The Holocene (34) 1167-1180
Middle and Late Holocene sediments have not been extensively sampled in Lake Tanganyika, and much remains unknown about the response of the Rift Valley’s largest lake to major environmental shifts during the Holocene, including the termination of the African Humid Period (AHP). Here, we present an integrated study (sedimentology, mineralogy,...
