Ryan E. Brown, Christine M. Mayer, Corbin David Hilling, Song S. Qian, James Roberts
2024, Management of Biological Invasions (15) 519-534
Invasive grass carp Ctenopharyngodon idella spawning was confirmed in Lake Erie with the collection of fertilized eggs in the Sandusky River, Ohio in 2015. Managers responded with initiation of adult grass carp removal in 2017. Hydrodynamic modeling revealed a potential spawning location in downtown Fremont, Ohio (41.3455; −83.1110), which was...
Simulated ground-motion records for the seismic assessment of monumental masonry structures
Shaghayegh Karimzadeh, Marco F. Funari, Simon Szabó, S. M. Sajad Hussaini, Sanaz Rezaeian, Paulo B. Lourenço
2024, Conference Paper
Earthquakes are natural disasters that can cause widespread devastation and loss of life. Simulated ground-motion records can be useful in regions with limited seismic stations or a history of damaging but infrequent earthquakes. This is especially true in areas with a high concentration of heritage masonry structures, which are especially...
Seismic response comparison of a historical masonry church subject to real and simulated ground motions
S. M. Sajad Hussaini, Claudio Sebastiani, Monica Capasso, Valerio Sabbatini, Shaghayegh Karimzadeh, Sanaz Rezaeian, Silvia Santini, Paulo B. Lourenço
2024, Conference Paper
In recent years, advanced numerical models and high-performance computing have facilitated the utilization of ground motion time series in the assessment of the non-linear dynamic behavior of historic masonry structures. Since recorded accelerograms can be sparse for specific analysis conditions, stochastic ground motion simulations have become a viable alternative to...

2024, Geomorphology (466)
Sedimentary processes on Mars have contributed to a plethora of landforms, both ancient and modern. Many of these are aeolian- or fluvial-formed constructs that meet the morphologic criteria for dunes and ripples but are clearly lithified and part of the rock record. This study conducted a survey of Mars using...

Laura Buarque, Max Frenzel, Britta Bookhagen, Carolin Kresse, Michael Schmidt, Nedal T. Nassar, Elisa Alonso, Ensieh Shojaeddini, Dirk Sandmann
2024, Resources Policy (99)
Recently, there has been considerable recent controversy whether current and new lithium mines will be able to supply the rapidly growing needs of the electromobility transition. Mineral exploration projects are typically active for many years, and only some become operational mines. From exploration to production, the projects go through several...
Limited preservation of strike-slip surface displacement in the geomorphic record
Nadine G. Reitman, Yann Klinger, Richard W. Briggs, Ryan D. Gold
2024, Journal of Geophysical Research: Solid Earth (129)
Offset geomorphic markers are commonly used to interpret slip history of strike-slip faults and have played an important role in forming earthquake recurrence models. These data sets are typically analyzed using cumulative probability methods to interpret average amounts of slip in past earthquakes. However, interpretation of the geomorphic record to...

2024, Ecosphere (15)
Identifying how species respond to system drivers such as weather, climate, habitat, and resource availability is critical in understanding population change. In coastal areas, the transfer of nutrients across the marine and terrestrial interface increases complexity. Nesting populations of bald eagles (Haliaeetus leucocephalus) along the Pacific coast of North America,...

Semi-automated methods to develop a unified geographic information system dataset
Jason L. Shapiro, David I. Donato
2024, Techniques and Methods 11-C10
Geospatial data describing the topography, natural features, human-built features, and land uses of a particular area or region can come from independent data providers and, therefore, vary in format, data encoding, and geographic coverage. Because of the complexity of the processes and procedures required for unifying these heterogeneous data into...

Most random-encounter-model density estimates in camera-based predator-prey studies are unreliable
Sean M. Murphy, Benjamin S. Nolan, Felicia Chen, Kathleen Longshore, Matthew T. Simes, Gabrielle A. Berr, Todd Esque
2024, Animals (14)
Population estimates are often required for identifying relationships between predators and their prey and to inform conservation and management actions. The random encounter model (REM) estimates population density of wildlife lacking individually unique markings, based on photographs or videos from remote camera-traps. However, the REM has strict sampling and input...
Using crustal-scale refraction data of joint inversions of Rayleigh-wave dispersion curves and H/V spectral ratios for Atlantic Coastal Plain velocity structure, eastern U.S.
Thomas Pratt, Stefano Parolai, Valerio Poggi, Ilaria Dreossi
2024, Bulletin of the Seismological Society of America (115) 270-295
Shallow shear‐wave velocities (Vs) sometimes are estimated from joint inversions of horizontal‐to‐vertical (H/V) spectral ratios and surface‐wave dispersion curves derived from ambient noise or small active sources. Here, we evaluate carrying out these inversions using Rayleigh‐wave dispersion curves computed from crustal‐scale P‐wave seismic refraction data. We use data from...

2024, Scientific Data (11)
The Colorado River drains about 8% of the conterminous United States, provides water for 40 million people, and is one of the most overallocated rivers in the world. As the upper Colorado River Basin (UCOL) contributes an estimated 92% of the total basin natural streamflow, knowledge of the location and...
