1. The Santa Ana River in the Los Angeles region of California demonstrates common habitat degradation symptoms that are characteristic of the urban stream syndrome. These impacts have altered the Santa Ana River community structure, with few species as impacted as the native Santa Ana sucker (sucker; Pantosteus santaanae). 2. Consequently,...
Signatures of wave erosion in Titan’s coasts
Rose Elizabeth Palermo, Andrew D. Ashton, Jason M. Soderblom, Samuel P. D. Birch, Alexander G. Hayes, J. Taylor Perron
2024, Science Advances (10)
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it is unclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theoretical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion, but the observational evidence...

2024, Northwest Science (97) 134-145
In August 2020, the 3-m tall Pilchuck River Diversion Dam was removed from the Pilchuck River, allowing free fish passage to the upper third of the watershed for the first time in over a century. The narrow, 300-m long impoundment behind the dam was estimated to hold 4,000–7,500 m3 of sand...

Daniel J. Catizone, Travis M. Thomas, Christina Romagosa, Margaret Lamont
2024, Estuaries and Coasts
Coastal habitats are some of the most imperiled due to climate change and anthropogenic activities. As such, it is important to understand population dynamics of the species that may play a role in regulating coastal systems. Diamondback terrapins in Northwest Florida have been understudied, which has resulted in a gap...

Linhao Xu, Don DeAngelis
2024, Theoretical Ecology
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....
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...

Evaluation of short-term mussel test for estimating toxicity
Ning Wang, James L. Kunz, Chris D. Ivey, Danielle M. Cleveland, Jeffery Steevens
2024, Environmental Toxicology and Chemistry
Effect concentrations of ammonia, nickel, sodium chloride, and potassium chloride from short-term 7-day tests were compared to those from standard chronic 28-day toxicity tests with juvenile mussels (fatmucket, Lampsilis siliquoidea) to evaluate the sensitivities of the 7-day tests. The effect concentrations for nickel (59 µg Ni/L), chloride...
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...
Uncertainty in ground-motion-to-intensity conversions significantly affects earthquake early warning alert regions
Jessie Saunders, Annemarie S. Baltay, Sarah E. Minson, Maren Böse
2024, The Seismic Record (4) 121-130
We examine how the choice of ground‐motion‐to‐intensity conversion equations (GMICEs) in earthquake early warning (EEW) systems affects resulting alert regions. We find that existing GMICEs can underestimate observed shaking at short rupture distances or overestimate the extent of low‐intensity shaking. Updated GMICEs that...

Diel temperature signals track seasonal shifts in localized groundwater contributions to headwater streamflow generation at network scale
David Rey, Danielle K. Hare, Jennifer Burlingame Hoyle Fair, Martin 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...

The polar bear (Ursus maritimus) is a species particularly vulnerable to the effects of climate change. As the climate warms, polar bears will be forced to move to more suitable habitats which are likely to shrink, adapt to the new conditions, or decline in population size. However, the genomic diversity...
