Survival rate of the larval stage is an important driver of fish recruitment. To understand mechanisms regulating larval survival it is important to understand the relative importance of abiotic and biotic factors that shape larval spatial distributions. We studied larval Coregonus distributions in surface waters (surface to 1 m) by repeatedly sampling study...
Metal release from manganese nodules in anoxic seawater and implications for deep-sea mining dewatering operations
Yang Xiang, Janelle M. Steffen, Phoebe J. Lam, Amy Gartman, Kira Mizell, Jessica N. Fitzsimmons
2024, ACS ES&T Water (4) 2957-2967
The potential mining of deep-sea polymetallic nodules has been gaining increasing attention due to their enrichment in metals essential for a low-carbon future. To date, there have been few scientific studies concerning the geochemical consequences of dewatered mining waste discharge into the pelagic water column, which...
Detection of periodic peaks in Karenia brevis concentration consistent with the time-delay logistic equation
Bruce E. Kurtz, James E. Landmeyer, James K. Culter
2024, Science of the Total Environment (946)
The logistic equation models single-species population growth with a sigmoid curve that begins as exponential and ends with an asymptotic approach to a final population determined by natural system carrying capacity. But the population of a natural system often does not stabilize as it approaches carrying capacity. Instead, it...
Boulders modulate hillslope-channel coupling in the northern Alaska Range
Adrian Bender, Richard O. Lease
2024, Geology (52) 695-699
Active orogens balance tectonic rock uplift with erosion, commonly via river incision coupled to landslide denudation of “threshold” hillslopes, but sediment’s role in this feedback is unclear. We report fluvial geometry, and sediment size, prevalence, and mobility across two ≤600-m-tall gneissic northern Alaska...

Tucker R. Burch, Joel P. Stokdyk, Aaron D. Firnstahl, Sarah Opelt, Rachel M. Cook, Joe Heffron, Amanda Brown, Claire E. Hruby, Mark A. Borchardt
2024, Environmental Science & Technology Water (4) 2789-2802
Fecal contamination of surface water can cause acute gastrointestinal illness (AGI) among recreators. AGI risk varies among human, livestock, and wildlife fecal sources, but the prevalence of individual sources is unknown for most recreational sites. We estimated AGI risk for six sites near Des Moines, Iowa,...
Satellite telemetry reveals high-use internesting areas and international foraging extent for loggerhead turtles tagged in southeast Florida, USA
Glenn D. Goodwin, Kristen Hart, Abby C. Evans, Derek A. Burkholder
2024, Endangered Species Research (54) 245-259
Developing conservation strategies for highly migratory marine species relies on understanding their spatial distributions. Nesting populations of female loggerhead (Caretta caretta) turtles typically travel from widely dispersed foraging areas and make use of common internesting areas between nesting events. Protection of these areas is essential to the conservation of...

Suresh A. Sethi, Alex L. Koeberle, Anna J. Poulton, Daniel W. Linden, Duane R. Diefenbach, Frances E. Buderman, Mary Jo Casalena, Kenneth Duren
2024, Scientific Reports (14)
Advances in tagging technologies are expanding opportunities to estimate survival of fish and wildlife populations. Yet, capture and handling effects could impact survival outcomes and bias inference about natural mortality processes. We developed a multistage time-to-event model that can partition the survival process into sequential phases that reflect the tagged...

Jonathan Daily, Michael H. Darin, Donna L. Whitney, M. Cosca, Christian Teyssier, Nuretdin Kaymakci, Tuna Eken, Mary R. Reid, Susan L. Beck
2024, GSA Today (34) 4-12
The East Anatolian Fault Zone (EAFZ) is a plate-bounding strike-slip fault capable of hosting large earthquakes, as demonstrated by the extremely damaging February 2023 Mw 7.8 and Mw 7.7 mainshocks of the Kahramanmaraş earthquake sequence. Deformation related to this boundary, part of the Anatolia-Arabia-Africa (A3) Triple Junction, is diffuse, as was shown...
Kit foxes demonstrate adaptive compromise characteristics under intraguild predation pressure by coyotes in the Great Basin desert
Nadine A. Pershyn, Eric M Gese, Erica Francis Stuber, Bryan M. Kluever
2024, Scientific Reports (14)
Coyotes (Canis latrans) are believed to contribute to declining kit fox (Vulpes macrotis) numbers in the Great Basin desert through intraguild predation. Intraguild prey have been shown to exhibit adaptive compromise, whereby an animal increases selection for risky, but food-rich areas during times of food stress (i.e. winter). We evaluated...

Kyle R. Anderson, Mengyang Gu
2024, JGR Machine Learning and Computation (1)
Elastic continuum mechanical models are widely used to compute deformations due to pressure changes in buried cavities, such as magma reservoirs. In general, analytical models are fast but can be inaccurate as they do not correctly satisfy boundary conditions for many geometries, while numerical models are slow and may require...
