Erin Peterson, Rex Thors, Danielle Frechette, Joseph D. Zydlewski
2023, Journal of Fisheries Management (43) 1052-1065
Objective Sea Lamprey Petromyzon marinus provide important ecological services within their native range, such as nutrient cycling, and can also act as a prey source for other species. Adult Sea Lamprey must access freshwater rivers to spawn, and because of this they are susceptible to changes in river connectivity. Human-made structures, such...

Merging machine learning and geostatistical approaches for spatial modeling of geoenergy resources
Gamze Erdogan Erten, Oktay Erten, C. Ozgen Karacan, Jeff Boisvert, Clayton V. Deutsch
2023, International Journal of Coal Geology (276)
Geostatistics is the most commonly used probabilistic approach for modeling earth systems, including quality parameters of various geoenergy resources. In geostatistics, estimates, either on a point or block support, are generated as a spatially-weighted average of surrounding samples. The optimal weights are determined through the stationary variogram model which accounts...
Analysis of high-resolution single channel seismic data for use in sediment resource evaluation, eastern Texas and western Louisiana Continental Shelf, Gulf of Mexico
James G. Flocks, Arnell S. Forde, Stephen T. Bosse
2023, Scientific Investigations Report 2023-5093
Shallow subsurface geologic data recorded as high-resolution seismic profiles are used to interpret the geology of coastal and marine systems. These data were originally recorded on paper rolls that are stored in geophysical archives. Data collection has since converted to entirely digital formats, yet the analog data are still useful...

Tanner Corless Smith, Tara B.B. Bishop, Michael C. Duniway, Miguel L. Villarreal, Anna C. Knight, Seth M. Munson, Eric K. Waller, Ryan Jensen, Richard A. Gill
2023, Biological Invasions (25) 3839-3859
Invasive annual grasses can promote ecosystem state changes and habitat loss in the American Southwest. Non-native annual grasses such as Bromus spp. and Schismus spp. have invaded the Mojave Desert and degraded habitat through increased fire occurrence, severity, and shifting plant community composition. Thus, it is important to identify and...

David C. Buesch, Bruce W. Bridenbecker
2023, Conference Paper, 2023 Desert Symposium Field Guide and Proceedings: Mines of the Mojave
Mining in the Marble Mountains of southeastern California was active in the earliest 1900s and gradually declined to very few active mines by 1959. Most mining consisted of hard-rock prospects and mines, with a few soft-rock prospects and one mine. The Marble Mountains are a 10 km by 30 km,...

2023, Journal of Heredity (114) 681-689
Rattlesnakes play important roles in their ecosystems by regulating prey populations, are involved in complex coevolutionary dynamics with their prey, and exhibit a variety of unusual adaptations, including maternal care, heat-sensing pit organs, hinged fangs, and medically-significant venoms. The western rattlesnake (Crotalus oreganus) is one of the widest ranging...

Leila Chapron, Ilsa B. Kuffner, Dustin W. Kemp, Ann M. Hulver, Elise Keister, Anastasios Stathakopoulos, Lucy Bartlett, Erin O. Lyons, Andrea G. Grottoli
2023, Communications Earth & Environment (4)
The iconic and threatened Caribbean coral, Acropora palmata, is an essential reef-ecosystem engineer. Understanding the processes underpinning this coral’s survival and growth is essential to restoring this foundational species. Here, we compared replicate A. palmata colonies transplanted along 350 km of Florida’s offshore coral reef to determine holobiont and/or environmental...

Wesley W. Boone, Christopher E. Moorman, Adam Terando, David J. Moscicki, Bret A. Collier, Michael J. Chamberlain, Krishna Pacifici
2023, Climate Change Ecology (6)
Climate change may induce mismatches between wildlife reproductive phenology and temporal occurrence of resources necessary for reproductive success. Verifying and elucidating the causal mechanisms behind potential mismatches requires large-scale, longer-duration data. We used eastern wild turkey (Meleagris gallopavo silvestris) nesting data...

2023, Landslides (20) 2421-2436
The steep, tectonically active terrain along the Central California (USA) coast is well known to produce deadly and destructive debris flows. However, the extent to which fire affects debris-flow susceptibility in this region is an open question. We documented the occurrence of postfire debris floods and flows following the landfall...

2023, Bulletin of the Seismological Society of America (113) 2377-2415
The 2020–2023 southwestern Puerto Rico seismic sequence, still ongoing in 2023, is remarkable for its multiple‐fault rupture complexity and elevated aftershock productivity. We applied an automatic workflow to continuous data from 43 seismic stations in Puerto Rico to build an enhanced earthquake catalog with ∼180,000 events for the 3+ yr...

Vicki S. Blazer, Mark A Matsche, Erin L. Pulster
2023, Diseases of Aquatic Organisms (154) 107-130
Macrophage aggregate (MA) abundance in fish is a useful general biomarker of contaminant exposures and environmental stress. Hepatic and splenic MAs were evaluated in semi-anadromous white perch Morone americana (Gmelin, 1789) from the urbanized Severn River (S) and the more rural Choptank River (C), Chesapeake Bay. Fish were collected from different...

Vicki S. Blazer, Mark A Matsche, Erin L. Pulster
2023, Diseases of Aquatic Organisms (154) 85-105
White perch Morone americana (Gmelin, 1789) from the Chesapeake Bay (USA) watershed have a high incidence of liver disease, including neoplasms of bile duct origin. Fish collected seasonally from spring 2019 to winter 2020 from the urban Severn River and the more rural Choptank River were evaluated for hepatic lesions. Biliary...

M.A. Baker, E.C. Ingram, D.L. Higginbotham, Brian J. Irwin, A.G. Fox
2023, Endangered Species Research (51) 203-214
The Atlantic sturgeon Acipenser oxyrinchus oxyrinchus was once of great commercial importance in many coastal rivers of the eastern USA. Over the 19th and 20th centuries, most historical stocks of Atlantic sturgeon were depleted by human activities. Estimating recruitment for the remaining populations is challenging due to sampling constraints, limited age...
Biotic and abiotic factors shaping bat activity in Maryland soybean fields
Lauren D. Maynard, W. Mark Ford, John D. Parker, Susan R. Whitehead
2023, Ecosphere (14)
Bats are important pest control agents in agriculture. Yet, the underlying fine-scale biotic and abiotic mechanisms that drive their foraging behaviors and responses to insect outbreaks are unclear. Herbivore-induced plant volatiles (HIPVs) can attract both invertebrate and vertebrate natural enemies that use the chemical plant cues to locate insect prey....
Cryptic tolerant fish species and their potential effect on index of biotic integrity (IBI) scores
Bryson G. Hilburn, Mary Freeman, Katelyn M. Lawson, Steven J. Rider, Carol E. Johnston
2023, Ecological Indicators (154)
Indices such as the Index of Biotic Integrity (IBI) are often used by management agencies to estimate the abstract property of stream health. These indices are usually predicated on the belief that certain fish species are tolerant to environmental perturbation while others are sensitive. Species are usually designated as either...
