2023, Earth and Planetary Science Letters (616)
Large volume rhyolitic ignimbrite volcanism is a significant contributor to the evolving crust. The introduction of high-silica material into the upper crust, differentiation within the middle crust, and partial melting in the lower crust contributes to geochemical and isotopic evolution of the crust. Developing accurate models...

Assessing global elevation models for mapping the low elevation coastal zone
Dean B. Gesch
2023, Conference Paper, Geomorphometry 2023 proceedings
Elevation data are critical for assessments of coastal hazards, including sea-level rise (SLR), flooding, storm surge, tsunami impacts, and wave run-up. Previous research has demonstrated that the quality of data used in elevation-based hazard assessments must be well documented and applied properly to assess potential impacts. Global digital elevation models...
Neonicotinoid sunflower seed treatment, while not detected in pollen and nectar, still impacts wild bees and crop yield
Laura T. Ward, Michelle Hladik, Aidee Guzman, Ariana Bautista, Nicholas Mills
2023, Agrochemicals (2) 279-295
Neonicotinoid seed treatments are commonly used in agricultural production even though their benefit to crop yield and their impact on pollinators, particularly wild bees, remains unclear. Using an on-farm matched pair design in which half of each field was sown with thiamethoxam treated seed and half without, we assessed honey...
Combining field observations and high-resolution numerical modeling to demonstrate the effect of coral reef roughness on turbulence and its implications for reef restoration design
Benjamin K Norris, Curt Storlazzi, Andrew W. M. Pomeroy, Kurt J. Rosenberger, Joshua B. Logan, Olivia Cheriton
2023, Coastal Engineering (184)
Coral reefs are effective natural barriers that protect adjacent coastal communities from hazards such as erosion and storm-induced flooding. However, the degradation of coral reefs compromises their ability to protect against these hazards, making degraded reefs a target for restoration. There have been limited field and numerical modeling studies conducted...
Wave runup and inundation dynamics on a perched beach
Carly Portch, Michael Cuttler, Mark L. Buckley, Jeff Hansen, Ryan Lowe
2023, Geomorphology (435)
Sandy beaches perched over rocky shore platforms are common globally, yet their mixed sand and rocky morphology present challenges for quantifying and predicting wave runup and inundation. For typical linear beach profiles, simple relationships can be made between vertical runup and horizontal inundation based on beach slope. However, as topographic...

Daniel Mark Griffith, Kristin B. Byrd, Lee Anderegg, Elijah Allen, Demetrios Gatziolis, Dar A. Roberts, Rosie Yacoub, Ramakrishna Nemani
2023, Proceedings of the Natural Academy of Sciences (120)
Biogeographic history can set initial conditions for vegetation community assemblages that determine their climate responses at broad extents that land surface models attempt to forecast. Numerous studies have indicated that evolutionarily conserved biochemical, structural, and other functional attributes of plant species are captured in visible-to-short wavelength infrared, 400 to 2,500...

Helaine W. Markewich, Douglas A. Wysocki, G. Norman White, Joe B. Dixon
2023, Scientific Investigations Report 2023-5062
The age and source of the late Pleistocene Roxana Silt in the Mississippi Valley have been studied since the middle 1800s. Published age and paleoenvironmental data for the Roxana Silt in the Mississippi Valley show that deposition occurred from late marine isotope stage 5 (MIS5) through late marine isotope stage...
Horizontal integrity a prerequisite for vertical stability: Comparison of elevation change and the unvegetated-vegetated marsh ratio across southeastern USA coastal wetlands
Neil K. Ganju, Zafer Defne, Caroline Schwab, Michelle Moorman
2023, Estuaries and Coasts
Surface elevation tables (SETs) estimate the vertical resilience of coastal wetlands to sea-level rise (SLR) and other stressors but are limited in their spatial coverage. Conversely, spatially integrative metrics based on remote sensing provide comprehensive spatial coverage of horizontal processes but cannot track elevation trajectory at high resolution. Here, we...

Talesha Karish, Gary W. Roemer, David K. Delaney, Craig D. Reddell, James W. Cain III
2023, Journal of Wildlife Management (87)
Expansion of feral burro (Equus asinus) populations across the southwestern United States is causing human–wildlife conflicts including rangeland degradation, competition with livestock and native species, and burro–vehicle collisions. On the Fort Irwin National Training Center (NTC) in California, feral burros interfere with military training...
Geographic isolation reduces genetic diversity of a wide-ranging terrestrial vertebrate, Canis lupus
S.A. Frévol, D. R. MacNulty, M. C. Anderson, H. D. Cluff, L. David Mech, M. Musiani
2023, Ecosphere (14)
Genetic diversity is theorized to decrease in populations closer to a species' range edge, where habitat may be suboptimal. Generalist species capable of long-range dispersal may maintain sufficient gene flow to counteract this, though the presence of significant barriers to dispersal (e.g., large water...
Evidence for the importance of invasive Dreissena veligers as a novel prey item for larval fish in Lake Huron
Ellary C Marano, David Bunnell, Patricia Dieter, Karen M. Alofs
2023, Hydrobiologia (850) 3497-3615
The establishment of invasive dreissenid mussels Dreissena polymorpha and Dreissena rostriformis bugensis in the Laurentian Great Lakes has affected multiple aspects of the ecosystem. However, the effects of their larvae (veligers) on lower trophic levels are relatively unknown. Previous research has documented that some larval fishes consume veligers, but it...

2023, Quaternary Science Reviews (311)
The Great Dismal Swamp wetland, spanning >400 km2 along the Virginia and North Carolina border, was shaped by a complex combination of geomorphic, climatic, and anthropogenic forcings during the last 14,000 years.

Laura K. Shannon, Bianca Viggiano, Raul Bayoan Cal, Larry G. Mastin, Alexa R. Van Eaton, Stephen A. Solovitz
2023, Journal of Geophysical Research: Atmospheres (128)
Explosive eruptions expel volcanic gases and particles at high pressures and velocities. Within this multiphase fluid, small ash particles affect the flow dynamics, impacting mixing, entrainment, turbulence, and aggregation. To examine the role of turbulent particle behavior, we conducted an analogue experiment using a particle-laden jet. We...
